Abstract
Objective: To explore the molecular mechanism of circDDX17 regulating the proliferation and apoptosis of non-small cell lung cancer cells by targeting the miR-223-3p/RIP3 molecular axis. Methods: The expression levels of circDDX17, miR-223-3p, and RIP3 in human normal lung epithelial cell lines BEAS-2B and non-small cell lung cancer cells H1299, A549, and H446 were detected by reverse transcription-quantitative real-time polymerase chain reaction (RT-qPCR). The plasmids of pcDNA, pcDNA-circDDX17, anti-miR-con, anti-miR-223-3p, pcDNA-circDDX17 and miR-con, pcDNA-circDDX17 and miR-223-3p mimics were transfected into H1299 cells. 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H tetrazolium bromide (MTT) assay was used to detect the cell proliferation. Flow cytometry was used to detect the cell cycle and cell apoptosis. Plate cloning experiment was used to detect cell proliferation ability. The dual luciferase report experiment was applied to verify the targeting relationship between miR-223-3p with circDDX17 and RIP3. Western blot was used to detect the protein expression of cyclinD1, CDK2, cleaved caspase-3 and Bax. Results: The expression levels of circDDX17 and RIP3 mRNA in H1299, A549, and H446 cells were significantly reduced (P<0.05), the expression level of miR-223-3p mRNA was significantly increased (P<0.05) compared with BEAS-2B. The cell viability [(69.46±4.68)%], the number of cell clones (83.49±7.86), the proportion of cells in S phase [(22.52±1.41) %], the protein expression levels of cyclinD1 and CDK2 in PCDNa-CircDDX17 group were lower than those in pcDNA group [(97.54±7.72)%, 205.03±13.37, (28.69±1.49)%, respectively, P<0.05], while the percentage of G0/G1 phase cells [(64.45±3.56)%], apoptosis rate [(18.36±1.63)%], the protein expression levels of cleaved caspase-3 and Bax in pcDNA-circDDX17 group were higher than those of pcDNA group [(51.33±2.76) % and (5.21±0.54) %, respectively, P<0.05]. The viability [(72.64±5.44)%], the number of cell clones (78.16±8.23), the proportion of S-stage cells [(21.34±1.59) %], the protein expression levels of CyclinD1 and CDK2 in anti-miR-223-3p group were lower than those in anti-miR-con group [(103.47±6.25)%, 169.32±14.53, (28.43±1.26)%, respectively, P<0.05]. Percentage of G0/G1 phase cells [(62.86±3.28)%], apoptosis rate [(14.64±1.67)%], the protein expression levels of cleaved caspase-3 and Bax in the anti-miR-223-3p group were higher than those of anti-miR-con group [(51.33±2.71)% and (4.83±0.39)%, respectively, P<0.05]. MiR-223-3p has complementary sites with circDDX17 or RIP3. The viability [(135.45±9.28)%], the number of cell clones (174.64±10.68), the proportion of S-phase cells [(26.39±2.25)%], the protein expression levels of cyclinD1 and CDK2 in pcDNA-circDDX17+miR-223-3p group were higher than those in pcDNA-circDDX17+miR-con group [(101.56±6.68)%, 107.65±7.62, (21.64±1.72)%, P<0.05]. Percentage of G0/G1 phase cells [(56.64±2.76)%], apoptosis rate [(8.34±0.76)%], the protein expression levels of cleaved caspase-3 and Bax in pcDNA-circDDX17+miR-223-3p group were lower than those of pcDNA-circDDX17+miR-con group [(64.03±3.48)% and (15.21±1.18)%, respectively, P<0.05]. Conclusion: circDDX17 could inhibit the proliferation and induce apoptosis of non-small cell lung cancer cells via targeting the miR-223-3p / RIP3 molecular axis.

Abstract
Compensating for the intrinsic attosecond chirp (atto-chirp) of wideband high-order harmonics in the water window region is a significant challenge, in order to obtain isolated attosecond pulses (IAPs) with a width of tens of attoseconds (as). Here, we propose to realize the generation of IAP with duration as short as 20 as, central energy of 365 eV, and bandwidth exceeding 150 eV from chirp-free high harmonics generated by a four-color driving laser, without the necessity for atto-chirp compensation with natural materials. Unlike any other gating methods that an IAP arises from only one electron ionization event, we take advantage of the interference between harmonic radiation produced by multiple ionizing events. We further demonstrate that such chirp-free short IAP survives after taking account of macroscopic propagation effects. Given that the synthesized multicolor laser field can also effectively increase the harmonic flux, this work provides a practical way for experiments to generate the broad bandwidth chirp-free IAPs in the water window region.

Abstract
Resina Draconis is a traditional Chinese medicine, with the in-depth research, its medicinal value in anti-tumor has been revealed. Loureirin A is extracted from Resina Draconis, however, research on the anti-tumor efficacy of Loureirin A is rare. Herein, we investigated the function of Loureirin A in melanoma. Our research demonstrated that Loureirin A inhibited the proliferation of and caused G0/G1 cell cycle arrest in melanoma cells in a concentration-dependent manner. Further study showed that the melanin content and tyrosinase activity was enhanced after Loureirin A treatment, demonstrated that Loureirin A promoted melanoma cell differentiation, which was accompanied with the reduce of WNT signaling pathway. Meanwhile, we found that Loureirin A suppressed the migration and invasion of melanoma cells through the protein kinase B (AKT)/mammalian target of rapamycin (mTOR) signaling pathway. Taken together, this study demonstrated for the first time the anti-tumor effects of Loureirin A in melanoma cells, which provided a novel therapeutic strategy against melanoma.

Abstract
Objective: To examine the safety and effectiveness of thin struct bare stents for the treatment of spontaneous isolated dissection of the superior mesenteric artery (SIDSMA). Methods: The data of 32 patients admitted to First Hospital of Jiaxing (20 cases) and Jinling Hospital (12 cases) with SIDSMA from January 2016 to January 2021 were retrospectively analyzed. There were 27 males and 5 females, aging (54.8±9.4) years (range: 36 to 75 years). All patients were treated with thin struct bare stents. Controllable spring coils were used to fulfill the false lumen in 2 cases. Symptoms, vascular remodeling pattern at the SIDSMA lesion, and patency of the stents were observed during follow-up. Results: The surgical success rate was 100%. According to the length of the lesions and stents, the number of stents implanted was 1 in 17 cases, 2 in 11 cases and 3 in 4 cases. The angiography showed that blood flow in the stent was smooth and that the false lumen disappeared or weakened. The numerical rating scale for abdominal pain decreased from 6.1±1.5 (range: 4 to 10) preoperatively to 1.0 (1.0) (range: 0 to 3) 1 hour postoperatively (W=528, P<0.01). The compression rate of the true lumen of the superior mesenteric artery decreased from (92.3±6.7)% (range: 25% to 94%) preoperatively to 0.8 (1.2)% (range: 0 to 3.2%) 1 month postoperatively (W=528, P<0.01). The primary patency rate of CT angiography at 1 month postoperatively was 100%. The vascular remodeling rate was (92.3±6.7)% (range: 80% to 100%). All patients were followed for (46.3±17.0) months (range: 24 to 76 months). The cumulative patency rates in 1, 2 and 5 years were all 100%. Conclusion: The use of thin struct bare stents for SIDSMA is safety and efficacy.

Abstract
Objective: To analyze the incidence and risk factors of ventricular septal defect (VSD) in Qingdao. Methods: A prospective cohort study design was used to include pregnant women who underwent prenatal screening in Qingdao between August 2018 and June 2020 (the whole population coverage). VSD was diagnosed according to the pulse oxygen saturation and heart auscultation, and the final diagnosis was made according to the echocardiography of VSD positive newborns within postnatal day 7. Results: The study included 115 238 live births, among which 388 were diagnosed as VSD, with an incidence of 3.37‰. The results of multivariate logistic regression analysis showed that mother with postgraduate level (OR=1.61, 95%CI: 1.00-2.58, P=0.049) (compared with junior high school and below), preterm birth history (OR=2.90, 95%CI: 1.47-5.70, P=0.002), and pregnancy history of congenital heart disease (OR=5.98, 95%CI: 2.63-14.73, P<0.001) were risk factors for VSD. Compared with female infants, the overall risk of VSD in male infants was relatively low (OR=0.74, 95%CI: 0.60-0.91, P=0.005). Conclusions: The incidence of VSD in Qingdao is 3.37‰. The risk factors of VSD include higher maternal education level, pregnancy history of congenital heart disease and preterm birth history. Moreover, the overall risk of VSD in male infants is low.

Abstract
Hepatocellular carcinoma (HCC) is a malignant tumor with a high rate of recurrence and a poor prognosis. Here, we investigated the effect and the potential antitumor mechanism of Gamabufotalin (CS-6) against HCC. Our results show that CS-6 strikingly reduced cell viability, inhibited colony formation, and promoted apoptosis in Hep3B and Huh7 cells. In vivo, CS-6 inhibited HCC xenograft tumor growth with no toxicity to normal tissues. Mechanistically, we found that CS-6 could induce cytoprotective autophagy through the mTOR-ULK1 signaling pathway through downregulation of p62 and upregulation of LC3 II/LC3 I. Meanwhile, CS-6 activated caspase-3 and PARP mediated apoptosis, and the caspase inhibitor Z-VAD-FMK blocked the CS-6-induced cell death in HCC cells. Moreover, autophagy and apoptosis were found to have antagonistic effects in Hep3B and Huh7 cells. Both the autophagy inhibitor chloroquine (CQ) and the mTOR activator MHY1485 blocked autophagy and further enhanced CS-6-induced apoptosis. Taken together, we demonstrated for the first time that CS-6 promotes apoptosis and cytoprotective autophagy through the mTOR signaling pathway in HCC, which proposes a novel strategy for HCC therapy.

Abstract
We theoretically present the waveform controls of terahertz (THz) radiations generated from homogeneous and rippled plasma within inhomogeneous external electrostatic field. The Particle-in-cell (PIC) simulations is implemented to demonstrate generation and controllability of three types of THz pulses: single frequency THz pulse in homogeneous plasma, broadband THz pulse and dual frequency THz pulse in rippled plasma. The single frequency THz pulse can be tuned via shifting the knob of electron density of homogeneous plasma. Waveform of broadband THz pulse can be regulated into an envelope-like shape by varying amplitude of electron density of rippled plasma. The two center frequencies' interval of dual frequency THz pulse can be controlled by wave numbers of density distribution of rippled plasma. This work provides a potential means to generate the dual frequency THz pulses with two harmonic frequencies (ω+Ωω, Ω=2) or incommensurate frequencies (ω+Ωω, Ω=1.7,1.8, 2.2…).

Abstract
Sanggenon C is a flavonoid extracted from the root bark of white mulberry, which is a traditional Chinese medicine with anti-inflammatory, antioxidative, and antitumor pharmacological effects. In this study, sanggenon C was found to inhibit human gastric cancer (GC) cell proliferation and colony formation, induce GC cell cycle arrest in the G0-G1 phase, and promote GC cell apoptosis. Moreover, sanggenon C was found to decrease the level of mitochondrial membrane potential in GC cells and inhibit mitochondrial fission. Mechanistically, RNA sequencing, bioinformatics analysis, and a series of functional analyses confirmed that sanggenon C inhibited mitochondrial fission to induce apoptosis by blocking the extracellular regulated protein kinases (ERK) signaling pathway, and constitutive activation of ERK significantly abrogated these effects. Finally, sanggenon C was found to suppress the growth of tumor xenografts in nude mice without obvious side effects to the vital organs of animals. This study reveals that sanggenon C could be a novel therapeutic strategy for GC treatment.

Abstract
The two-color strong-field mixing in gas medium is a widely used approach to generate bright broadband terahertz (THz) radiation. Here, we present a new, to the best of our knowledge, and counterintuitive method to promote THz performance in the two-color scheme. Beyond our knowledge that the maximum THz generation occurs with two-color foci overlapped, we found that, when the foci of two-color beams are noticeably separated along the propagation axis resulting in cascading plasmas, the THz conversion efficiency is surged by one order of magnitude and the bandwidth is stretched by more than two times, achieving 10-3 conversion efficiency and >100 THz bandwidth under the condition of 800/400 nm, ∼35 fs driving lasers. With the help of the pulse propagation equation and photocurrent model, the observations can be partially understood by the compromise between THz generation and absorption due to the spatial redistribution of laser energy in cascading plasmas. The present method can be extended to a mid-infrared driving laser, and new records of THz peak power and conversion efficiency are expected.

Abstract
BACKGROUND Upper limb venous thrombosis (ULVT) is rarer than lower-extremity deep venous thrombosis, and is related to Paget-Schroetter syndrome, central venous catheterization, and malignancy. There are few reports of pulmonary embolism (PE) from upper-extremity vein thrombosis due to surgery. Herein, we report two cases of PE that originated from upper limb venous thrombosis on the surgical side in two patients undergoing modified radical mastectomy for breast cancer. These cases challenge the traditional theory that PE originate only from the lower extremities.
CASE SUMMARY We describe two female patients, aged 68 and 65 years, respectively, who had undergone modified radical mastectomy for breast cancer. They did not have a central venous catheter and did not undergo preoperative neoadjuvant chemotherapy. They were transferred to the intensive care unit due to symptomatic PE on the first day after surgery. Colour Doppler ultrasound identified fresh thrombosis in their upper limb veins, which was the presumed source of the PE. They all received anticoagulation therapy, and one of them experienced bleeding that required discontinuation of the drug. Ultimately, they were discharged in stable condition.
CONCLUSION ULVT as a source of PE after breast cancer surgery cannot be ignored.

Abstract
Terahertz (THz) radiations from graphene are expected to provide a powerful light source for their wide applications. However, their conversion efficiencies are limited with either long-duration or few-cycle single-color laser pulses. Here, we theoretically demonstrate that THz waves can be efficiently generated from monolayer graphene by using a long-duration two-color laser pulse at normal incidence. Our simulated results show that low-frequency THz emissions are sensitive to the phase difference between two colors, the laser intensity, and the fundamental wavelength. Their dependence on these parameters can be very well reproduced by asymmetry parameters accounting for electron populations of conduction and valence bands. On the contrary, a newly defined σ parameter including the Landau-Zener tunneling probability cannot precisely predict such dependence. Furthermore, the waveform of THz electric field driven by two-color laser pulses exhibits the typical feature of a half-cycle pulse.

Abstract
Objective: To investigate the clinical features of pediatric ulcerative colitis (UC) and analyze the risk factors of disease relapse. Methods: The clinical data of 79 children with UC diagnosed in Beijing Children's Hospital, Capital Medical University from January 2016 to February 2021 were retrospectively analyzed. They were divided into early relapse group and non-early relapse group according to the clinical relapse within 12 months after diagnosis. T-test, rank sum test, χ2 test or Fisher's exact test were used to compare the variables between the 2 groups, including the clinical features, laboratory examination results and treatments. The Logistic regression was used to analyze the risk factors of early relapse. The cumulative relapse rate during follow-up was calculated by Kaplan-Meier method. Results: Among the 79 UC children, 46 were males and 33 were females, and the age of onset was 10.6 (6.4, 12.7) years. The children were mainly characterized by extensive disease (E3) and pancolitis (E4) (51/79, 65%), moderate to severe activity (48/79, 61%) and moderate to severe inflammation of colonic mucosa (71/79, 90%). Thirty-eight (48%) patients had atypical phenotype and 17 (22%) had extraintestinal manifestations. The follow-up period was 43.9 (22.8, 61.3) months, and of the 41 patients rechecked with colonoscopy, 7 (17%) had disease progression. According to Kaplan-Meier analysis, the cumulative relapse rate of the 79 cases at 3 months, 6 months, 1 year and 2 years after diagnosis were 27% (21/79), 47% (37/79), 57% (45/79) and 73% (53/73), respectively. There were 45 children (57%) in early relapse group and 34 (43%) in non-early relapse group. In early relapse group, hemoglobin and mucosal healing rate were both significantly lower (105 (87, 122) vs. 120 (104, 131) g/L, 28% (7/25) vs. 7/9, Z=-2.38, χ²=4.87, both P<0.05). The rate of steroid-dependent, E3 and step-up therapy during the induction period were all significantly higher than those in non-early relapse group (11/19 vs. 1/12, 24% (11/45) vs. 6% (2/34), 29% (13/45) vs. 6% (2/34), χ²=5.67, 4.85, 6.66, all P<0.05). Multivariate Logistic regression analysis showed that extraintestinal manifestations (OR=4.33, 95%CI 1.05-17.83), E3 (OR=8.27, 95%CI 1.47-46.46) and step-up therapy during the induction period (OR=5.58, 95%CI 1.01-30.77) were independent risk factors for early relapse. Conclusions: Pediatric UC is usually extensive and severe, with atypical phenotype, a high rate of relapse and a risk of disease progression. Extraintestinal manifestations, E3 and step-up therapy during the induction period are independent risk factors for early relapse.

Abstract
We theoretically investigate the atomic-orbital-resolved vortex-shaped photoelectron momentum distributions (PMDs) and ionization probabilities by solving the two-dimensional time-dependent Schrödinger equation (2D-TDSE) of neon in a pair of delayed counter-rotating circularly polarized attosecond pulses. We found that the number of spiral arms in vortex patterns is twice the number of absorbed photons when the initial state is the ψm=±1 state, which satisfy a change from c2n+2 to c2n (n is the number of absorbed photons) rotational symmetry of the vortices if the 2p state is replaced by 2p+ or 2p- states. For two- and three-photon ionization, the magnetic quantum number dependence of ionization probabilities is quite weak. Interestingly, single-photon ionization is preferred when the electron and laser field corotate and ionization probabilities of 2p- is much larger than that of 2p+ if the proper time delay and wavelength are used. The relative ratio of ionization probabilities between 2p- and 2p+ is insensitive to laser peak intensity, which can be controlled by changing the wavelength, time delay, relative phase and amplitude ratio of two attosecond pulses.

Abstract
Objective: Due to its various anatomical variations and numerous branches, the gastrocolic vein trunk (Henle trunk) is the most common site to develop bleeding and other complications in laparoscopic right hemicolectomy for colon cancer. This study aims to investigate the role of ileocolic vein (ICV) joining with Henle trunk, a rare anatomical variation. Methods: A rare case whose ICV was newly found to involve in the formation of Henle trunk during laparoscopic resection of right hemicolon cancer was reported as right gastroepiploic vein+ right colic vein+superior right colic vein+ICV. This anatomical variation was confirmed by multi-slice spiral CT coronal two-dimensional reconstruction of right hemicolon angiography. The literatures about ICV participating in formation of Henle trunk were systematically searched from PubMed, The Cochran Library, CNKI net and Wanfang database, and the occurrence probability and composition of its anatomical variation were analyzed. Results: This was a 47-year-old female patient who underwent laparoscopic right hemicolectomy. When the vessels were dissected during operation, it was found that ICV did not accompany the ileocolic artery, but directly flowed into Henle trunk. Two-dimensional reconstructed CT images of right hemicolon vessels showed that the composition of Henle trunk was rarely varied, which was composed of right gastroepiploic vein, right colonic vein, superior right colonic vein and ICV. Five literatures were enrolled from literature retrieval. A total of 12 cases with ICV participating in the construction of Henle trunk were reported, with a probability of 0.27%-6.31% and 6 forms of the formation of Henle trunk. In this case, Henle trunk was made up of right gastroepiploic vein, right colonic vein, upper right colonic vein and ICV, which was reported for the first time. Conclusions: ICV involving in Henle trunk is a rare vascular variation, and this type of variation should be fully recognized. Careful dissection during operation is necessary to prevent intraoperative bleeding caused by improper operation.

Abstract
The concept of total mesorectal resection provides a quality control standard that can be followed for radical resection of rectal cancer, but some anatomical problems are still controversial. Compared with traditional open surgery, laparoscopic radical rectal surgery has better surgical vision, better neurological protection, better operating space. However, if the surgeon has insufficient understanding of the anatomy, collateral damage may occur, such as uncontrollable bleeding during the operation, postoperative urination and defecation dysfunction and so on. Based on the interpretation of the researches at home and abroad, combined with the clinical experience, we elucidate some associated issues, including anatomic variation of inferior mesenteric vessels, the controversy of inferior mesenteric artery ligation plane, the controversy of lymph node dissection in No. 253, the anatomical variation of middle rectal artery, and the anatomical controversy of lateral lymph node dissection in rectal cancer, in order to provide better cognitive process for the clinical front-line surgeons.

Abstract
BACKGROUND Pancreaticopleural fistula (PPF) is a rare disease, especially in children. Conservative treatment and surgery are traditional therapies, but surgery is invasive. The emergence of endoscopic retrograde cholangiopancreatography (ERCP) has provided a new noninvasive treatment for PPF and may become the first choice for children with PPF.
AIM To explore the treatment response to ERCP for PPF in children.
METHODS Seven children with PPF were hospitalized in the Gastroenterology Department of Beijing Children’s Hospital from December 2007 to May 2019. Data on these seven patients’ clinical characteristics, diagnosis, treatments, and outcomes were analyzed, and their treatment responses following surgery and ERCP were compared. The correlation between the length of hospital stay and conservative treatment was analyzed. Peer-reviewed articles written in English and Chinese published from January 2009 to December 2019 were obtained from various open data sources and reviewed.
RESULTS The seven patients comprised three boys and four girls with a mean age of 6.57 ± 3.26 years. The main symptoms were chest tightness and pain (n = 4), intermittent fever (n = 3), dyspnea (n = 3), and abdominal pain (n = 1), and all patients had bloody pleural effusion. All seven patients were diagnosed with PPF by magnetic resonance cholangiopancreatography, and all were initially treated conservatively for a mean of 34.67 ± 22.03 d with a poor response. Among five patients who underwent ERCP, one required surgery because of intubation failure; thus, the success rate of ERCP was 80%. Two patients were successfully treated with surgery (100%). The postoperative hospital stay of the two patients treated by surgery was 20 and 30 d, respectively (mean of 25 d), and that of the four patients treated by ERCP ranged from 12 to 30 d (mean of 19.25 ± 8.85 d). The recovery time after ERCP was short [time to oral feeding, 4-6 d (mean, 5.33 ± 1.15 d); duration of closed thoracic drainage, 2-22 d (mean, 13.3 d)]. Analysis of previous cases of PPF published worldwide during the past decade showed that the treatment success rate of ERCP is not lower than that of surgery. There was no significant difference in the postoperative hospital stay between surgery (16 ± 10.95 d) and ERCP (18.7 ± 6.88 d, P > 0.05). A positive linear correlation was found between the overall hospital stay and ERCP intervention time (R2 = 0.9992).
CONCLUSION ERCP is recommended as the first-choice treatment for PPF in children. ERCP should be performed as early as possible if conditions permit.

Abstract
We propose a scheme to achieve the photonic and the phononic state transfers via the topological protected edge channel based on a one-dimensional small optomechanical lattice. We find that the optomechanical lattice can be mapped into a Su-Schrieffer-Heeger model after eliminating the counter rotating wave terms. By dint of the edge channel of the Su-Schrieffer-Heeger model, we show that the quantum state transfer between the photonic left and the right edge states can be achieved with a high fidelity. Especially, our scheme can also achieve another phononic state transfer based on the same channel via controlling the next-nearest-neighboring interactions between the cavity fields; this is different from the previous investigations achieving only one kind of quantum state transfer. Our scheme provides a novel, to the best of our knowledge, path to switch two different kinds of quantum state transfers in a controllable way.

Abstract
Flexible photodetector shows great potential applications in intelligent wearable devices, health monitoring, and biological sensing. In this work, single crystal β-tellurium nanowires were grown on flexible muscovite by molecular beam epitaxy, constructing high-density ordered nanomesh structure. The prepared photodetectors based on tellurium nanomesh exhibit excellent mechanical flexibility, fast response in a broad range from ultraviolet to near-infrared, and good photosensitivity. We found that the flexible photodetectors with Shottky contact drastically suppressed dark current, while the response speed was lowered in comparison to the devices with ohmic contact, as holes would take a long time to tunnel through the Shottky barrier between metal and p-type Te. Moreover, the photoresponse of flexible Shottky photodetectors can be modulated by piezoelectricity of tellurium, and pronounced photocurrent increase after bending many times. Under external stress, polarization charges could tune Shottky barrier height of the metal/tellurium, resulting in variation of photocurrent. This research not only explores the broadband photoresponse and piezoelectric effect of tellurium nanomesh, but also promotes the integration and development of broadband flexible optoelectronic devices.

Abstract
Objective: To investigate the clinical characteristics of invasive Haemophilus influenzae (HI) infection in children. Methods: The clinical manifestations, laboratory examinations and treatment outcomes of 84 children with HI infection confirmed by bacterial culture in 7 tertiary children's hospitals from 2014 to 2018 were analyzed retrospectively. Results: Among the 84 cases, 50 were males. The age was 1.54 years (ranged from 5 days to 13 years).Twenty cases (24%) had underlying diseases and 48 cases (57%) had not received antibiotics before collecting specimens. Eighty-two cases (98%) had fever and 75 cases (89%) had clear infection foci, among which 31 cases (37%) had meningitis and 27 cases (32%) had pneumonia. Blood culture was positive in 62 cases (74%), cerebrospinal fluid culture was positive in 10 cases (12%), blood culture and cerebrospinal fluid culture were both positive in 11 cases (13%). Antibiotics susceptibility test showed that 27% (22/82) of all HI strains produced β-lactamases and 48% (37/77) strains were resistant to ampicillin. The drug resistance rates to cefuroxime, ampicillin-sulbactam, trimethoprim-sulfamethoxazole and azithromycin were 25% (20/80) , 20% (9/45) , 71% (44/62) and 19%(11/58), respectively. All strains were sensitive to meropenem, levofloxacin and ceftriaxone. After sensitive antibiotic therapy, 83% (70/84) of all patients were cured and improved, the mortality rate and loss of follow-up rate were 13% (11/84) and 4% (3/84) respectively. Conclusions: Meningitis and pneumonia are common presentation of invasive HI infections in children. Mortality in HI meningitis children is high and the third generation of cephalosporins, such as ceftriaxone can be used as the first choice for the treatment of invasive HI infection.

Abstract
OBJECTIVE To analyse the clinical and imaging data of patients with renal cell carcinoma (RCC) with inferior vena cava tumor thrombus (IVCTT), and to assess the diagnostic efficacy of ultrasound, enhanced computed tomography (CT) and enhanced magnetic resonance imaging (MRI) in the diagnosis of RCC with IVCTT combined with bland thrombus was assessed. METHODS We retrospectively analyzed the clinical and imaging data of 56 RCC patients with IVCTT who underwent radical nephrectomy and IVC thrombectomy between January 2014 and July 2018 in Department of Urology, Peking University Third Hospital. All the patients underwent US, enhanced CT and enhanced MRI preoperatively, and all the cases were confirmed with RCC with IVCTT by histological evaluation. RESULTS The criteria of RCC with IVCTT combined with bland thrombus was confirmed by intraoperative observation and postoperative pathology. The 56 patients were divided into bland thrombus group (n=18) and non bland thrombus group (n=38). Compared the two groups, it was found that the length of IVCTT was longer [(10.50 ± 5.55) cm vs.(6.66 ± 3.73) cm, P=0.014]; the ratio of diameter of IVCTT to maximum coronal diameter of IVC was closer to 1 [1.0 (0.7, 1.0) vs. 0.9 (0.2, 1.0), P=0.004]; the proportion of lower limb edema was higher [66.7(12/8)% vs.5.3%(2/36), P=0.005];the proportion of segmental resection or interrupt of IVC was higher [66.7%(12/18) vs.15.8%(6/38), P<0.001], with statistical significance. Compared with the three imaging methods of US, enhanced CT and MRI, the highest sensitivity was MRI (77.8%), the highest specificity was enhanced MRI and enhanced CT (97.4%), the highest accuracy was enhanced CT and enhanced MRI (83.9%), the highest positive predictive value was enhanced CT (90.9%) and the highest negative predictive value was enhanced MRI (89.2%). CONCLUSION For the patients that RCC with IVCTT combined with bland thrombus, the length of IVCTT is longer, and the ratio of the diameter of IVCTT to the maximum corona diameter of IVC is closer to 1, and more likely to cause lower limb edema. Preoperative comprehensive evaluation of multiple images is needed to improve the accuracy of diagnosis.

Abstract
OBJECTIVE To summarize the experience of diagnosis and operation related to massive adrenal area tumor with venous tumor thrombus in clinic. METHODS From October 2017 to March 2019, a total of 8 cases of massive adrenal area tumor (>7 cm) with venous tumor thrombus were admitted at Peking University Third Hospital including 5 males and 3 females with mean age 50.6 years (31-62 years). There were 6 cases on the right side and 2 cases on the left side. The first symptoms included abdominal discomfort, hypertension, Cushing syndrome and abnormal menstruation; special past history included cirrhosis and lung cancer. Computed tomography (CT) and routine endocrine hormone tests were examined. Preoperative imaging confirmed 5 cases masses with tumor thrombus in inferior vena cava (IVC) and 1 case with tumor thrombus in left renal vein. Two cases presented with tumor thrombus in central adrenal vein were found intraoperatively. Open adrenalectomy and thrombectomy were performed in 4 cases of right side complicated with high tumor thrombus of inferior vena cava. Laparoscopic adrenalectomy and thrombectomy were performed in 3 cases, including 2 cases on the right and 1 case on the left. The case with tumor thrombus in left renal vein gave up operation. The patients were followed up with outpatient and telephone. RESULTS The mean size of the tumor was 8.9 cm (7-11 cm), the mean operative time was 319 min (120-510 min), while the estimated blood loss was 629 mL (50-1 200 mL). Intraoperative blood transfusion was required in 2 cases and 1 case encountered wound infection. The pathological types included pheochromocytoma, adrenocortical carcinoma, adrenal metastases of haptic carcinoma, and leiomyosarcoma. The case with left lung carcinoma who underwent left pneumonectomy one month before was highly suspected adrenal metastases of lung carcinoma. Tumor thrombus of pheochromocytoma was combined with blood thrombus. Capsule of adrenocortical carcinoma was fragile in adrenocortical carcinoma. Abundant blood supply existed in adrenal metastases. The leiomyosarcoma had unabundant blood supply and invaded IVC to form tumors thrombus. The mean follow-up time was 8.4 months (1-15 months). One case with adrenocortical carcinoma died after 1 year in the follow-up. CONCLUSION We present the rare cases of different pathological types of massive adrenal tumors with tumor thrombus extending into the IVC extension or other vein. Preoperative diagnosis needs comprehensive evaluation and perfect preoperative preparation. Surgery is difficult and varied. Open approach as well as retroperitoneal laparoscopic approach is feasible.

Abstract
OBJECTIVE To investigate the impact of preoperative diagnostic ureteroscopy and biopsy (UB) on radical nephroureterectomy (RNU) and the prognosis of upper tract urothelial carcinoma (UTUC). METHODS The clinical data of UTUC patients receiving RNU between Jan. 2007 and Dec. 2016 were retrospectively collected. The median follow up time was 40 months. The operation time and blood loss of RNU were compared between UB group and non-UB group. Subgroup analyses were conducted according to the time interval between UB and RNU, and surgery methods of lower ureter. The linear regression model was used to adjust for other common factors that impacted operation time. RESULTS A total of 163 UTUC patients were included in the final analysis. For the lower ureter, open ureterectomies were performed in 91 patients (55.9%), while retroperitoneal laparoscopic ureterectomies were performed in 72 patients (44.1%). A total of 110 (67.5%) patients received preoperative UB. Compared with non-UB group, the average operation time of UB group was significantly longer [(252.5±79.8) min vs. (221.3±79.8) min, P=0.019], but no difference of blood loss was found (median, 50 mL vs. 50 mL, P=0.143). In subgroup analysis, the average operation time of RNU was significantly prolonged when RNU was performed after 1 week of UB (P=0.023). Meanwhile, the median blood loss of RNU increased significantly when it was done after 2 weeks of UB compared with non-UB group (100 mL vs. 50 mL, P=0.012). UB was also significantly prolonged the operation time of RNU in retroperitoneal laparoscopic ureterectomy group (P=0.012). In multivariable analysis, UB (P=0.049), ≥pT3 (P=0.039), pN+ (P=0.018) and ureterectomy method (P=0.005) were independent risk factors of prolonged operation time. The 3-year cancer specific survival (CSS) rate was 87.2% in our cohort. UB had no significant impact on cancer specific survival (P=0.435). CONCLUSION UB was an independent risk factor of prolonged RNU time, but did not significantly influence cancer specific survival of upper tract urothelial carcinoma patients.

Abstract
OBJECTIVE Larotaxel is a new chemical structure drug, which has not been marketed worldwide. Accordingly, the standard identification and quantification methods for larotaxel remain unclear. The spectrometric analyses were performed for verifying weight molecular formula, molecular weight and chemical structure of larotaxel. Besides, a quantification method was developed for measuring larotaxel in the liposomes. METHODS The molecular formula, molecular weight and chemical structure of larotaxel were studied by using mass spectrometry (MS), infra-red (IR), nuclear magnetic resonance (NMR) and ultraviolet-visible (UV-vis) spectrometric techniques. The absorption wavelength of larotaxel was investigated by UV-vis spectrophotometry full-wavelength scanning. Besides, a quantification method was developed by high performance liquid chromatography (HPLC), and then validated by measuring the encapsulation efficacy of larotaxel liposomes. RESULTS The four spectral characteristics of larotaxel were revealed and the corresponding standard spectra were defined. It was confirmed that larotaxel had the structure of tricyclic diterpenoids, with the molecular formula of C45H53NO14, the molecular weight of 831.900 1, and the maximum absorption wavelength of 230 nm. The quantitative method of larotaxel was established by using HPLC with a reversed phase C18 column (5 μm, 250 mm×4.6 mm), a mobile phase of acetonitrile-water (75:25, volume/volume), and a detection wavelength of 230 nm. The validation study exhibited that the established HPLC method was stable, and had a high recovery and precision in the quantitative measurement of larotaxel in liposomes. In addition, a new kind of larotaxel liposomes was also successfully prepared. The particle size of the liposomes was about 105 nm, with an even size distribution. And the encapsulation efficiency of larotaxel in the liposomes was above 80%. CONCLUSION The present study offers reference standard spectra of larotaxel, including MS, IR, NMR, and UV-vis, and confirms the molecular formula, molecular weight and chemical structure of larotaxel. Besides, the study develops a rapid HPLC method for quality control of larotaxel liposomes.

Abstract
Objective: To summarize the clinical data including manifestations, diagnosis, treatment and prognosis of eosinophilic gastroenteritis (EGE) in children. Methods: A retrospective analysis was performed in 71 patients with pathologically proven EGE at Beijing Children's Hospital Affiliated to Capital Medical University from January 2008 to January 2017. Their clinical manifestations, laboratory and imaging examinations, endoscopic findings, histopathological examinations, and treatment were collected and analyzed. Results: Among 71 EGE cases, 47 (66%) cases were male and 24 (34%) cases were female, and the median age was 9.2 (0.2-16.5) years old. The main clinical manifestations included abdominal pain (76%, 54/71), vomiting (68%, 48/71), anorexia (54%, 38/71), weight loss (38%, 27/71), and diarrhea (37%, 26/71). There were 27 cases (38%) with a history of allergic diseases or family history. The median absolute value of eosinophil in peripheral blood of the 71 patients was 0.4 (0-36.8)×10(9)/L, and 27 cases (38%) showed an increase in eosinophil counts. Serum IgE was measured in 52 patients (104.3 (3.4- 3 000.0)×10(3) U/L), and 30 patients (58%) showed an increase in serum IgE. A large number of eosinophils ((41.0±8.5)/HP) were found in 3 patients' ascites. The endoscopic examination of upper gastrointestinal tract revealed hyperemic edema in 62 cases (87%), plaque in 44 cases (62%), erosion in 17 cases (24%) and ulceration in 16 cases (23%). Histopathologically, in 8 cases (11%) the disease involved both stomach and duodeneum, in 21 cases (30%) involved stomach only, and in 37 cases (52%) involved duodeneum only. In addition, in 6 cases (8%) the disease involved esophagus and in 10 cases (14%) involved colorectum. Microscopically, eosinophil counts averaged 67/HP, 33/HP, 40/HP and 38/HP in esophageal, gastric, duodenal and colorectal mucosa respectively. A total of 34 cases were treated with glucocorticoid, and all these patients had alleviation of symptoms, which occurred within 14.9 days on average, but EGE recurred in 11 cases (32%). Conclusions: The clinical symptoms and endoscopic findings of EGE are diverse and nonspecific. Histopathological examination of gastrointestinal mucosa is particularly important for the diagnosis. Glucocorticoid treatment is effective, but the patients with EGE are prone to relapse.

Abstract
OBJECTIVE To investigate the safety and feasibility of laparoscopic treatment for renal carcinoma with Mayo 0-2 level venous thrombosis. METHODS From January 2015 to February 2018, 58 renal carcinoma cases with venous thrombus underwent laparoscopic radical nephrectomy with inferior vena cava thrombectomy in Department of Urology, Peking University Third Hospital, of which, 51 cases were male, and 7 female, aged 29-82 years. According to the Mayo grade classification, 20 cases were level 0, 20 cases were level 1, and 18 cases were level 2, with left side being 22 cases, and right side 36 cases. The patients except for those complicated with hemorrhagic diseases, cardiac and pulmonary insufficiency, or those who could not tolerate anesthesia and surgical contraindications, underwent the operation after comprehensive examinations. RESULTS The 58 cases of renal tumor with venous tumor emboli were successfully completed with the surgeries, including 50 cases of totally laparoscopic surgery, 8 cases of laparoscopy surgery from convert to open (among the patients who were converted to open surgery, 7 were complicated with grade 2 tumor thrombus and 1 with grade 1 tumor thrombus). The main reasons for converting to open surgery were huge tumors (the largest of which was about 16 cm in diameter), severe adhesion and difficulty of separation. For different patients, different surgical methods and procedures were adopted according to the tumor direction and the different grade of tumor thrombus. Radical nephrectomy combined with vena cava tumor thrombus removal was performed in 55 cases and segmental resection of vena cava in 3 cases. The operation time was 132-557 min, and blood loss was 20-3 000 mL. Post-operative pathological types: 51 cases were clear cell carcinoma, 5 cases were type 2 of papillary carcinoma, 1 case was squamous cell carcinoma, and 1 case was chromophobe cell tumor. In the study, 47 cases were followed up for 1-36 months, and 4 cases died (the survival time was 5-15 months, with an average of 10.2 months). CONCLUSION Laparoscopic radical nephrectomy with inferior vena cava thrombectomy is a reasonable choice for renal tumor with Mayo 0-2 level venous thrombosis. For different tumor directions and different grades of tumor thrombus, an appropriate operation plan can give the maxim benefit to the patients with skillful surgeons.

Abstract
OBJECTIVE To investigate the safety and perioperative experience of the segmental resection of the vena cava. METHODS From May 2015 to July 2017, 92 renal tumor patients with venous tumor thrombus were treated in Peking University Third Hospital, of whom 17 underwent nephrectomy with resection of the invaded vena cava for renal tumor with tumor thrombus invading vena cava. The preoperative features included that 15 patients were male and 2 female, the mean age was (59.2±12.9) years (31-84 years), 6 cases were left sided and 11 right sided, and the mean diameter of the renal tumor was (9.1±3.7) cm (3-14.5 cm). RESULTS In this group of 17 cases, 5 patients underwent resection of the vena cava via laparoscopy (including 2 open conversions), and 12 via open procedures (including 2 cardiopulmonary bypasses). The mean operation time was (430.4±120.7) min (284-694 min) and the mean intraoperative blood loss was (2 918.8±2 608.2) mL (300-10 000 mL). The vena cava from the bottom to the top was transected. The median length of the tumor thrombus in the vena cava was 10 cm (3-21 cm). Postoperative complications were found in 11 patients, including grade I in 1 case, grade II in 7 cases, grade IV in 2 cases and grade V in 1 case according to the Clavien system. The median postoperative creatinine was 116 μmol/L (79-645 μmol/L) with 2 patients needing dialysis. The postoperative pathology revealed that renal clear cell carcinoma in 10 cases, papillary carcinoma in 5 cases, urothelial carcinoma in 1 case and fusiform cell sarcoma in 1 case. During the median follow-up of 8 (1-28) months, 1 patient died during perioperative period, 1 patient died from multiple metastasis in 9 months postoperatively, 3 patients found distant metastasis and 2 cases remained lower extremity edema after operation. CONCLUSION The segmental resection of the vena cava may be a good choice for non-metastatic renal tumors with tumor thrombus invading vena cava. The short term follow-up results revealed a satisfactory safety and feasibility.

Abstract
Objective:To study the method and feasibility in reconstruction of platysma myocutaneous flap of defects caused by hypopharyngeal cancer resection. Method:Twelve cases underwent reconstruction with the platysma myocutaneous flap of hypopharyngeal soft defect were investigated. All cases received 2 times preoperative induction chemotherapy followed by hypopharyngeal cancer resection with laryngeal function preservation and the neck lymph node dissection. Platysma myocutaneous flap was used to repair the hypopharyngeal soft tissue defect. Result:All the flaps survived. Three weeks after surgery, all patients can eat without pharyngeal fistula and dysphagia, but pharyngeal foreign body sensation. Three cases of cough after surgery, improved after training. After postoperative radiotherapy, flap survived without secondary necrosis. Laryngeal function of all cases was retained, and only one case with cannula maintained. Conclusion:Preoperative induction program can effectively reduce the lesion. The placenta myocutaneous flap has rich blood supply, strong anti-infectivity. It is an effective method to repair the hypopharyngeal tissue defect with the placenta myocutaneous flap.

Abstract
Objective: To analyze the clinical manifestations, diagnosis, treatment and prognosis of intestinal lymphangiectasia (IL) in children in order to improve the skills of diagnosis and treatment of IL. Method: Clinical manifestations, laboratory findings, gastroscopic findings, histopathological examinations and lymphatic radionuclide imaging assessments were analyzed retrospectively among 47 IL patients who were hospitalized in the Gastroenterology Department of Beijing Children's Hospital Affiliated to Capital Medical University from June 2007 to December 2015. All patients were followed up by telephone. According to the various causes, the patients were divided into the primary intestinal lymphangiectasia (PIL) group and secondary IL group, and their clinical manifestations were compared by t test, Rank sum test or Chi-square test. Result: In 47 IL patients, there were 38 children (81%) younger than 3 years old. There were 43 PIL patients (91%) and 4 secondary IL patients (9%). Between PIL and secondary IL, there were statistical differences in serum albumin (t=-3.950, P<0.005) , globulin(t=-2.850, P=0.007), age of onset(U=27.000, P=0.024), age at diagnosis(U=29.000, P=0.030) and course of disease(U=26.500, P=0.023), whereas there were no statistical differences in lymphocyte count, IgG, lymphatic radionuclide imaging, histopathology and gender(all P>0.05). Edema (44 cases, 94%), diarrhea (42 cases, 89%), accompanied with infection (35 cases, 74%) and ascites (30 cases, 64%) were the main clinical manifestations. In 47 IL patients, 45 patients were done gastroscopy and histopathological examinations, and there were 31 patients' histopathological examinations(69%) were positive. Forty patients were done lymphatic radionuclide imaging, and there was evidence of protein losing from gut via lymphatic radionuclide imaging in 39 patients(98%). Among 47 patients, 35 patients (74%) were followed up, 32 patients had good prognosis, 2 patient failed to show evidence of improvement, 1 patient died and no patient experienced a relapse till the end of the follow-up. In 35 patients, 28 patients were treated with medium chain triglycerides (MCT) dietary therapy, 26 patients showed improvement in symptoms, and 2 patients had no improvement. Among 35 patients with follow-up, there were 6 patients received surgical treatment, and their symptoms were improved. Conclusion: PIL are the majority of IL in children younger than 3 years old. The main clinical manifestations are edema, diarrhea, accompanied with infection and ascites. For the patients without the evidence of lymphangiectasia from duodenum histopathological examination, further consideration of lymphatic radionuclide imaging, clinical manifestations, and laboratory studies are needed to make a final diagnosis. MCT dietary therapy is the cornerstone of IL medical management.

Abstract
Objective: To determine the effects of different computed high b-value on diffusion weighted imaging (DWI) scores in Prostate Imaging Reporting and Data System version 2 (PI-RADS v2) of prostate cancer in peripheral zone. Methods: A retrospective study of 104 cases of prostate cancer in peripheral zone was conducted, all of the patients were histopathologically confirmed by transrectal ultrasound guided saturation biopsy or radical prostatectomy in Tongji Hospital of Tongji University from January 2012 to December 2015.All MRI imaging examinations were performed by using a 3.0T Siemens Verio MRI scanner.The imaging protocol consisted of high-resolution axial and sagittal T(2) weighted imaging (T(2)WI), axial acquired diffusion weighted imaging (aDWI) with b=0, 50, 1 000 s/mm(2) and dynamic contrast-enhanced (DCE) scans.Computed diffusion weighted imaging (cDWI) images with b=1 000, 1 400, 2 000 s/mm(2) were processed by Matlab.These three groups of cDWI images were analyzed according to the PI-RADS v2 criteria, and signal intensity of ratio (SIR) of lesions were analyzed by independent t test and one-way ANOVA in each group. Results: The numbers of cases with a DWI score of 2 and 5 were similar among three groups.Nine cases (33.3%) in all 27 cases with a DWI score of 3 on b=1 000 s/mm(2) upgraded to score 4 when b-value rose to 1 400 and 2 000 s/mm(2).The ratios of SIR of lesions in cases upgraded from DWI score 3 to 4 to those unchanged cases on b=1 400 and 2 000 s/mm(2) were 1.86±0.21 to 1.61±0.27 and 2.18±0.26 to 1.75±0.30, respectively (t=2.486, t=3.671, both P<0.05). In these 9 cases who upgraded to DWI score 4, SIRs of the lesion were significantly different between groups when b=1 000, 1 400 and 2 000 s/mm(2) (F=10.907, 33.768, 8.043, all P<0.05), and their SIRs increased with the rising of b-value. Conclusions: The computed high b-value (b≥1 400 s/mm(2)) mainly affects cases with a DWI score of 3, but DWI scores would not change neither in b=1 400 s/mm(2) nor in 2 000 s/mm(2) cases. For DWI score in PI-RADS v2 of prostate cancer in peripheral zone, b=1 400 s/mm(2) is probably of more scoring value than b=1 000 or 2 000 s/mm(2).

Abstract
OBJECTIVE To evaluate the effectiveness and safety of radical nephrectomy and inferior vena cava thrombectomy in the treatment of patients with Mayo III tumor thrombus, and to introduce our experience and surgical technique. METHODS The clinical data of 8 patients with Mayo III tumor thrombus from October 2014 to September 2016 were analyzed retrospectively. Of the 8 patients, 3 were male and 5 were female. The average age was (50.8±18.7) years (18 to 77 years). The average body mass index (BMI) was (22.7±4.4) kg/m2 (15.2 to 30.8 kg/m2). Imaging suggested the right renal tumor in all the 8 cases. The average tumor size was (7.9±2.5) cm. Open radical nephrectomy and inferior vena cava thrombectomy was conducted in 5 cases and laparoscopic surgery in 3 cases, and 1 case was converted to open surgery. RESULTS All the 8 surgeries were completed successfully with no death case. The average surgery time was (370.3±101.6) min, ranging from 272-567 min. The average vena cava blocked time was (41.0±12.1) min, ranging from 17-55 min. The blood loss volume was (1 181.3±915.7) mL, ranging from 200-3 000 mL. During the operation, 5 cases were infused with suspended red blood cells, the amount of blood transfusion was 800-2 000 mL. 3 cases were infused of plasma with 400-1 000 mL. The average hospital stay was 9-23 d, with an average of (14.1±4.0) d. In the 8 patients, 4 cases underwent inferior vena cava wall resection because of invasion by tumor thrombus. Preoperative serum creatinine was 60-101 μmol/L, with an average of (76.4±15.3) μmol/L. Serum creatinine 1 week after the operation was 74-127 μmol/L, with an average of (100.8±21.1) μmol/L. Pathological diagnosis showed 6 cases of clear cell carcinoma, 1 case of papillary carcinoma type II, and 1 case of Ewing's sarcoma. Among the 8 patients, early postoperative complications occurred in 5 cases. Postoperative complications were graded as level II, according to the Clavien classifications. The 8 cases were followed up for 2 to 24 months with an average of 11.3 months. There was 1 patient who suffered from lung metastasis. CONCLUSION Our initial clinical results show that radical nephrectomy and inferior vena cava thrombectomy is safe and effective for patients with Mayo III tumor thrombus. The wide extension of grade III vein tumor thrombus leads to the difficulty of operation technique. Sufficient preoperative preparation, rich operative experience and skills can improve the safety of operation.

Abstract
OBJECTIVE Testicular mixed germ cell tumor is mixed with embryonal carcinoma, choriocarcinoma, yolk sac tumor, teratoma, seminoma and other two or more components of the testicular tumor, the clinical is relatively rare and high degree of malignancy, this article will summarize its clinical features and optimize its treatment. METHODS A retrospective analysis of the clinical data of 22 patients with testicular tumor mixed germ cell in Peking University Third Hospital from May 1994 to November 2016 was conducted using a combination of statistical analysis and discussion of the relevant literature. RESULTS The mean age of the 22 patients was (30.8±10.4) years and the rate of cryptorchidism was 13.6%. The maximum diameter of the tumor was (5.1±2.7 ) cm. The pathological results suggested that 12 cases (54.5%) contained two different germ cell tumor components, 7 cases (31.8%) contained 3 different tumor components, 2 cases (9.2%) contained 4 different tumor components, and 1 case (4.5%) contained 5 different tumor components. Tumor constituent analysis included yolk sac tumors(16 cases, 72.7%), mature teratoma (7 cases, 31.8%), immature teratoma (5 cases, 22.7%), embryonal carcinoma (17 cases, 77.3%) , choriocarcinoma (4 cases, 18.1%) and seminoma (6 cases, 27.3%). American Joint Committee of Cancer tumor staging indicated 19 cases of stage I a tumor, 2 cases of stage IIa tumor and 1 case of stage IIIa tumor. The mean values of human chorionic gonadotropin, alpha-fetoprotein and lactate dehydrogenase were 414.50 MIU/mL, 242.95 μg/L, 196.95 U/L (preoperative) and 17.20 MIU /mL, 90.20 μg/L, 183.70 U/L (postoperative within a year), and the comparison of the P values between the preoperative and the postoperative within a year were 0.079, 0.043 and 0.624. Fourteen patients underwent retroperitoneal lymph nodes dissection. Most patients lived with long-term survival (94.4%) after operation. CONCLUSION Comprehensive treatment of radical orchiectomy with retroperitoneal lymphadenectomy combined with necessary radiotherapy or chemotherapy might help to control the tumor and achieve long-term survival for most patients with testicular mixed germ cell tumor.

ETHNOPHARMACOLOGY RELEVANCE Ginsenoside Rb1, a 20 (S)-protopanaxadiol, is a major active ingredient of Panax ginseng C.A. Meyer, which as the King of Chinese herbs, has been wildly used for the treatment of central nervous system diseases. Previous studies have shown that 20 (S)-protopanaxadiol possesses a novel antidepressant-like effect in the treatment of depression, whereas ginsenoside Rb1 in depression has been rarely reported. AIM OF THE REVIEW The present study was to investigate the antidepressant-like effect of ginsenoside Rb1 and its relevant mechanisms. MATERIALS AND METHODS The whole experiment was divided into two parts: one part we examined the antidepressant-like effect of ginsenoside Rb1 with open-field test (OFT), tail suspension test (TST), forced swim test (FST), 5-HTP induced head-twitch and reserpine response in mice, another part we used chronic unpredicted mild stress (CUMS) model to further explore the antidepressant-like effect of ginsenoside Rb1 with caffeine, fluoxetine and p-Chlorophenylalanine (PCPA) in rats. Furthermore, the levels of monoamine neurotransmitters of NE, 5-HT, DA and their metabolites 5-HIAA, DOPAC, HVA were all measured by ELISA kits after the CUMS protocol. RESULTS Our data indicated that 7 days treatment with ginsenoside Rb1 (4, 8, 10mg/kg, p.o.) significantly decreased immobility time in the FST and TST in mice, and played important roles in mice which were induced by 5-HTP (200mg/kg, i.p.) and reserpine (4mg/kg, i.p.). On the basis of CUMS model, 21 days treatment with ginsenoside Rb1 not only had effective interactions with caffeine (5mg/kg, i.p.), fluoxetine (1mg/kg, i.p.) and PCPA (100mg/kg, i.p.), but also significantly up-regulated the 5-HT, 5-HIAA, NE and DA levels in CUMS rats' brain, whereas HVA and DOPAC had no significant difference. Moreover, there was no alteration in spontaneous locomotion in any experimental group. CONCLUSIONS These results suggest that ginsenoside Rb1 exhibits significant antidepressant-like effect in behavioral tests, chronic animal model and drug interactions, its mechanisms mainly mediated by central neurotransmitters of serotonergic, noradrenergic and dopaminergic systems.

Abstract
The objective of this study was to assess whether vitamin D (VD) treatment alters the overall all-cause and cardiovascular mortalities in a chronic kidney disease (CKD) population. We systematically searched PubMed, EMBASE, Web of Science, and Cochrane Central Register of Controlled Trials without language restriction, until the publication date of 22 February 2016. All related literatures that compared VD treatment with non-VD treatment and reported the mortality of patients with CKD (including those undergoing dialysis) were identified. Pooled risk ratios (RR) and 95% confidence intervals (CI) were calculated by using the random- and fixed-effects models. Randomised controlled trials (RCTs) that used the intention-to-treat principle and observational studies (OSs) were analysed separately. For this study, 38 studies involving 223 429 patients (17 RCTs, n=1819 and 21 OSs, n=221610) were included. In the OSs, VD treatment was significantly associated with reductions in both all-cause and cardiovascular mortalities; however, such significant association was not found in the RCTs. The existing RCTs do not provide sufficient or precise evidence that VD supplementation affects the mortality of patients with CKD, although subsets of patients that could potentially benefit from VD treatment can be identified by using the existing data from the RCTs. Nevertheless, large-size RCTs are needed in the future to assess any potential differences in survival prospectively.

Abstract
Objective: To increase the recognition of pancreatic cystic fibrosis (PCF) in children and facilitate diagnosing and treatment of this rare entity. Method: This is a retrospective analysis of children who presented to Beijing Children's Hospital affiliated to Capital Medical University from January 2010 to December 2015. We describe their clinical features, laboratory testing and management. Result: Eleven children were diagnosed with PCF by genetic testing or sweat chloride test during these 5 years, including 4 boys and 7 girls. Their age ranged from 0.5-14.3 (mean 9.0±3.9) years. Family history was positive in 3 children. Significant clinical findings on presentation were: malnutrition 6, including 2 cases of mild, moderate and severe malnutrition each; diarrhea 4 (yellow mushy or watery stool with frequency ranging from 2-5 times a day), including 1 case of acute diarrhea and 3 of chronic diarrhea, 3 of them had steatorrhea; abdominal pain 3. All of them had pancreatic lesions shown by abdominal ultrasound. Blood tests showed 6 cases had elevated serum amylase and lipase. The main treatment was pancreatic replacement therapy and nutritional support. Conclusion: PCF is rare in children. Malnutrition, diarrhea and abdominal pain are the main clinical manifestations. Treatment is mostly pancreatic enzymes replacement and supportive care.

Abstract
OBJECTIVE To explore the ratio of lymphocyte subsets in peripheral blood of patients with aplastic anemia (AA) and patients with hypoplastic myelodysplastic syndrome (hypo-MDS) patients and to evaluate their significance. METHODS The clinical data of 181 cases of AA and 111 cases of hypo-MDS from January 2008 to December 2014 were collected from Blood Diseases Hospital of Chinese academy of medical sciences, and then the differences of lymphocyte subsets and its effect in 2 groups were analyzed. RESULTS CD4+/CD8+ ratio, proportion of CD3+ cells and its subsets CD3+CD4+/CD3+CD8+ cells in hypo-MDS group were not significant different from AA group (P>0.05). the proportion of CD3-CD16/CD56+ NK cells and CD3+CD57+T-LGL cells in hypo-MDS group was significantly higher than that in AA group (P<0.05, P<0.01), but CD19+ B lymphocyte percentage in hypo-MDS patients was lower than that in AA patients (P<0.05). After dividing group according to CD4+/CD8+ ratio, the ratios of CD3+ CD16/CD56+ NK cells and CD3+/CD57+ T-LGL cells were higher only in normal CD4+/CD8+ ratio group of hypo-MDS patients than those in AA patients, while the ratio of B lymphocytes was significant different in inverted CD4+/CD8+ ratio group between hypo-MDS and AA patients. The CD19+ B lymphocyte ratio in hypo-MDS patients was significantly lower than that in AA patients (P<0.05). As well, the levels of erythrocytes and platelets in peripheral blood between hypo-MDS and AA patients only in normal CD4+/CD8+ ratio group were significantly different, while the significant difference of WBC count and reticulocyte ratio were observed in high CD4+/CD8+ ratio and non-inverted CD4+/CD8+ ratio groups, respectively; the significant difference of bone marrow blast ratio and muture monocyte ratio was found in high CD4+/CD8+ ratio group. CONCLUSION The changes of lymphocyte subsets can be used as an reference indicator for differential diagnosis of hypo-MDS and AA. The comparative analysis of patients with these 2 kinds of diseases after dividing into subgroups according to ratio of CD4+/CD8+ cells is beneficial to differentiat diagnosis.

Abstract
Ascorbic acid (AsA), also known as ascorbate or vitamin C, is a natural organic compound in green plants that has antioxidant properties, and is an essential nutrient for humans. The tea plant, Camellia sinensis (L.) O. Kuntze, is an important global economic crop. Here, the expression profiles of genes related to AsA biosynthesis and recycling were analyzed in tea plants in response to temperature stress. Eighteen genes involved in AsA biosynthesis and recycling pathways were identified based on the transcriptome database. The expression levels of CsPGI1 in two varieties of tea plants ('Yingshuang' and 'Huangjinya') increased, peaked at 4 h, and then decreased in response to cold stress. In 'Yingshuang', the genes involved in AsA biosynthesis pathway rapidly responded to heat stress and substantially increased their expression levels at 1 h. The expression levels of CsMDHAR, CsDHAR1, and CsDHAR2 increased sharply at 1 h in response to heat stress in 'Yingshuang'. In contrast, the expression levels of CsMDHAR, CsDHAR1, and CsDHAR2 in 'Huangjinya' gradually increased during heat treatment from 1 to 24 h. The expression trends of two DHAR isoforms differed in 'Huangjinya' during cold stress. The expression patterns of AsA-related genes differed in the different tea plant varieties and depended on temperature. The genes involved in AsA biosynthesis and recycling pathways were induced by heat and cold stress. Our study provides useful data with which to improve the resistance of tea plants to cold and heat stress.

Abstract
OBJECTIVE To describe a feasible surgical technique for patients with renal cell carcinoma associated with a supradiaphragmatic tumor thrombus that avoids cardiopulmonary bypass procedure. METHODS We retrospectively analyzed 2 cases with right kidney tumor and tumor thrombus above the diaphragm treated in April and August, 2015. The two patients were both female, aged 73 and 67 years. The tumor sizes of right kidneys were 7.0 cm×6.3 cm×5.7 cm and 8.7 cm×7.0 cm×5.2 cm, and the tumor thrombuses were 1.3 cm and 1.8 cm above the diaphragm. The second patient had synchronous metastasis in right adrenal gland , and the tumor thrombus arose from the adrenal vein but not the renal vein. Intraoperative transesophageal echocardiography (TEE) was used to assess real-time mobility of the thrombus. A modified chevron incision was used, the right kidney was mobilized laterally and posteriorly, and the renal artery was identified, ligated, and divided. The infradiaphragmatic inferior vena cava (IVC) was exposed and isolated by mobilizing the liver off the diaphragm or to the left (piggyback liver mobilization, case 2). The central diaphragm tendon was dissected or incised in the midline until the supradiaphragmatic intrapericardial IVC was identified and gently pulled beneath the diaphragm and into the abdomen. The tumor thrombus was then "milked" downward out of the intrapericardial IVC under the guidance of TEE. The distal and proximal IVC to the tumor thrombus, porta hepatis, and left renal vein were clamped. Tumor thrombus was removed from the IVC. The IVC was sutured and vascular clamps were placed below the major hepatic veins. Pringle's maneuver was then released and hepatic blood drainage was permitted during closure of the remaining IVC. Related literature was reviewed. RESULTS Complete resection was successful through the transabdominal approach without CBP in both patients. Estimated blood loss was 1 500 mL and 2 000 mL, and 1 200 mL and 800 mL of blood were transfused. The postoperative courses were uneventful. Both patients subsequently underwent tyrosine-kinase inhibitor therapy. Both patients were alive without tumor recurrence or new metastasis during the follow-up of 6 months and 9 months. CONCLUSION In selected cases, renal cell carcinoma extending into the IVC above the diaphragm can be resected without sternotomy, CBP or DHCA.

Abstract
Hyalomma asiaticum tick, an important ectozoic parasite causes tickle, pain, anemia, weight loss, and paralysis in its hosts, which include humans, cattle, sheep, horses, camels, and hares. The 4D8 gene can be a potential vaccine candidate antigen for H. asiaticum. In the present study, we cloned and expressed the 4D8 gene of H. asiaticum from Xinjiang Province. Primers were designed according to the H. asiaticum tick 4D8 gene sequence available in GenBank. The gene was amplified by reverse transcription-polymerase chain reaction and the fragments were subcloned into the prokaryotic expression vector pET30a and the recombinant vector pET30a-4D8 was constructed. The expressed recombinant protein was purified and its biological activity was investigated by western blot. Results revealed that the recombinant protein was a biologically active fusion protein with a molecular weight of 20 kDa. The purified 4D8 protein would provide a strong foundation for further studies on this protein.

Abstract
AIM To explore the correlation between the expression level of vascular endothelial growth factor (VEGF) in non-small-cell lung cancer (NSCLC) tissue and quantitative parameters of spectral computed tomography (CT) imaging. MATERIALS AND METHODS Forty-eight patients with NSCLC underwent a spectral CT imaging protocol before surgical tumour resection. The repetition of iodine concentration, water concentration, and CT values at 40 keV in the region of interest were measured. The slopes of spectral attenuation curves (λHU) in the region were also calculated. The level of VEGF expression in the tumour tissue was measured using an immunohistochemical method (MaxVision method). The quantitative parameters of spectral CT imaging were compared among different levels of VEGF expression using one-way analysis of variance (ANOVA) and least significant difference (SLD) test. The correlation between VEGF expression and spectral CT imaging was estimated through Spearman's rank correlation analysis. RESULTS There were significant differences in iodine concentrations, λHU, and CT values at 40 KeV in NSCLC between the groups showing negative and moderately positive expression of VEGF (p=0.001, 0.000, and 0.001, respectively) as well as between those showing mildly and moderately positive expression of VEGF (p=0.047, 0.005, and 0.002, respectively). In addition, all of the iodine concentrations, λHU values, and CT values at 40 KeV displayed a significant and positive correlation with the level of VEGF expression (r=0.413, 0.458, and 0.393, respectively, p<0.05). CONCLUSIONS Quantitative parameters of spectral CT imaging may be helpful for evaluating the status of angiogenesis in NSCLC.

Abstract
OBJECTIVE To study the effect of sub-anesthetic doses of isoflurane and propofol on the postoperative cognitive function of rats with mild cognitive impairment (MCI) following orthopedic operation. METHODS Male sprague-dawley rats (n=100) were randomly divided into sham group and model group.Bilateral carotid artery was separated with no bilateral narrowing in the sham operation group while bilateral carotid artery was occluded in model group.After 30 days, Morris Water Maze test were used to select MCI rats. The proportion of the value that average escape latency in model group minused average escape latency in sham group less than 20% was marked as MCI rats. After 36 days, the rats with mild cognitive impairment were randomly divided into 4 groups (n=18). Iso group: Isoflurane (1.9%) 3 h, combination group: propofol (20 mg·kg(-1)·h(-1))+ isoflurane (1%) 3 h. Inhibitor with these two groups were respectively used the selective KCC2 inhibitor-DIOA 30 μg 15 min before anesthesia. Then rats received an open tibial fracture on the hind paw with an intramedullary fixation. The rats in sham group were only sutured skin incision. At the day 7 postoperatively, the Y maze test were used to test the change of cognition, nissl staining was used to observe the neurons apoptosis. Immunofluorescence was adopted to observe the neurons expressing GAD67/KCC2 and Western blot were applied to observe the protein level of KCC2 in hippocampus. RESULTS The rate of time spent in novel arm, the number of surviving neurons, the number of neurons expressing GAD67/KCC2 and protein expression levels of KCC2 in hippocampus in combination group were (52.94±2.04)%, (176.81±13.07), (196.72±8.02), (80.67±3.46)% respectively. The indexes in sham group were (53.44±2.45)%, (183.79±10.88), (207.45±13.17), (81.42±3.59)%, respectively. There was no significant difference compared with the sham group (all P>0.05). However these indexes in above two groups were higher than that in Iso group( (36.10±1.57)%, (97.21±8.23), (158.94±13.47), (43.22±4.91)%, all P<0.05). The indexes in inhibitor with Iso groups, combination group was lower compared with groups without inhibitor respectively (all P<0.05). CONCLUSION Compared with isoflurane, sub-anesthetic doses of isoflurane and propofol has no significant effect on postoperative cognition in rats with MCI, and its mechanism is to maintain KCC2 expression in hippocampus.

Abstract
The triangle sail mussel, Hyriopsis cumingii, is the most important freshwater pearl mussel in China. However, the mechanisms underlying its chitin-mediated shell and nacre formation remain largely unknown. Here, we characterized a chitin synthase (CS) gene (HcCS1) in H. cumingii, and analyzed its possible physiological function. The complete ORF sequence of HcCS1 contained 6903 bp, encoding a 2300-amino acid protein (theoretical molecular mass = 264 kDa; isoelectric point = 6.22), and no putative signal peptide was predicted. A myosin motor head domain, a CS domain, and 12 transmembrane domains were found. The predicted spatial structures of the myosin head and CS domains were similar to the electron microscopic structure of the heavy meromyosin subfragment of chicken smooth muscle myosin and the crystal structure of bacterial cellulose synthase, respectively. This structural similarity indicates that the functions of these two domains might be conserved. Quantitative reverse transcription PCR results showed that HcCS1 was present in all detected tissues, with the highest expression levels detected in the mantle. The HcCS1 transcripts in the mantle were upregulated following shell damage from 12 to 24 h post-damage, and they peaked (approximately 1.5-fold increase) at 12 h after shell damage. These findings suggest that HcCS1 was involved in shell regeneration, and that it might participate in shell and nacre formation in this species via chitin synthesis. HcCS1 might also dynamically regulate chitin deposition during the process of shell and nacre formation with the help of its conserved myosin head domain.

Abstract
The basic-region/leucine-zipper (bZIP) family is one of the major transcription factor (TF) families associated with responses to abiotic stresses. Many members of group A in this family have been extensively examined and are reported to perform significant functions in ABA signaling as well as in responses to abiotic stresses. In this study, 10 bZIP factors in carrot were classified into group A based on their DNA-binding domains. The cis-acting regulatory elements and folding states of these 10 factors were analyzed. Evolutionary analysis of the group A members suggested their importance during the course of evolution in plants. In addition, cis-acting elements and the folding state of proteins were important for DNA binding and could affect gene expression. Quantitative RT-PCR was conducted to investigate the stress response of 10 genes encoding the group A factors. Six genes showed responses to abiotic stresses, while four genes showed other special phenomenon. The current analysis on group A bZIP family TFs in carrot is the first to investigate the TFs of Apiaceae via genome analysis. These results provide new information for future studies on carrot.

Abstract
We observed the effect of hydrogen-rich medium on lipopolysaccharide (LPS)-induced human umbilical vein endothelial cells (HUVECs), hyaline leukocyte conglutination, and permeability of the endothelium. Endotheliocytes were inoculated on 6-well plates and randomly divided into 4 groups: control, H2, LPS, LPS+H2, H2, and LPS+H2 in saturated hydrogen-rich medium. We applied Wright's stain-ing to observe conglutination of hyaline leukocytes and HUVECs, flow cytometry to determine the content of vascular cell adhesion protein 1 (VCAM-1) and intercellular adhesion molecule 1 (ICAM-1), enzyme-linked immunosorbent assay to measure the E-selectin concentration in the cell liquor, the transendothelial electrical resistance (TEER) to test the permeability of endothelial cells, and Western blot and immunofluorescence to test the expression and distribution of vascular endothelial (VE)-cadherin. Compared with control cells, there was an increase in endothelium-hyaline leukocyte conglutination, a reduction in VCAM-1, ICAM-1, and E-selectin, and the TEER value increased obviously. Compared with LPS, there was an obvious reduction in the conglutination of LPS+H2 cells, a reduction in VCAM-1, ICAM-1, and E-selectin levels, and a reduction in the TEER-resistance value, while the expression of VE-cadherin increased. Fluorescence results showed that, compared with control cells, the VE-cadherin in LPS cells was in-complete at the cell joints. Compared with LPS cells, the VE-cadherin in LPS+H2 cells was even and complete at the cell joints. Liquid rich in hydrogen could reduce LPS-induced production of adhesion molecules and endothelium-hyaline leukocyte conglutination, and influence the expression and distribution of VE-cadherin to regulate the permeability of the endothelium.
