Abstract
Objectives: This study aims to explore the clinical significance of lateral pelvic sentinel lymph node biopsy (SLNB) using indocyanine green (ICG) fluorescence navigation in laparoscopic lateral pelvic lymph node dissection (LLND) and evaluate the accuracy and feasibility of this technique to predict the status of lateral pelvic lymph nodes (LPLNs). Methods: The clinical and pathological characteristics, surgical outcomes, lymph node findings and perioperative complications of 16 rectal cancer patients who underwent SLNB using ICG fluorescence navigation in laparoscopic LLND in the Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College during April 2017 and October 2022 were retrospectively collected and analyzed. The patients did not receive preoperative neoadjuvant radiotherapy and presented with LPLNs but without LPLN enlargement (MRI showed the maximum short axes of the LPLNs were ≥5 mm and <10 mm at first visit). Results: All 16 patients were successfully performed SLNB using ICG fluorescence navigation in laparoscopic LLND. Three patients underwent bilateral LLND and 13 patients underwent unilateral LLND. The lateral pelvic sentinel lymph nodes (SLNs) were clearly fluorescent before dissection in 14 patients and the detection rate of SLNs for these patients was 87.5%. Lateral pelvic SLN metastasis was diagnosed in 2 patients and negative results were found in 12 patients by frozen pathological examinations. Among the 14 patients in whom lateral pelvic SLNs were detected, the dissected lateral pelvic non-SLNs were all negative. All dissected LPLNs were negative in two patients without fluorescent lateral pelvic SLNs. The specificity, sensitivity, negative predictive value, and accuracy was 85.7%, 100%, 100%, and 100%, respectively. Conclusions: This study indicates that lateral pelvic SLNB using ICG fluorescence navigation shows promise as a safe and feasible procedure with good accuracy. This technique may replace preventive LLND for locally advanced lower rectal cancer.

Abstract
The study aimed to evaluate whether an intra-aortic balloon pump (IABP) could improve the prognosis of patients with cardiogenic shock (CS) of Stage C (Classic), Stage D (Deteriorating), and Stage E (Extremis) based on Society for Cardiovascular Angiography and Interventions (SCAI) classification. The hospital information database was searched, and the patients who met the diagnostic criteria of CS were included and treated following the same protocol. The association between IABP and the survival of patients at 1 month and 6 months were analyzed separately in SCAI stage C of CS, and stages D and E of CS. The multiple logistic regression models were used to separately evaluate whether IABP was independently associated with increased survival in stage C of CS, and stages D and E of CS. A total of 141 patients with stage C of CS and 267 patients with stages D and E of CS were included. In stage C of CS, IABP was significantly associated with improved survival of patients at 1 month [adjusted OR (95%CI)=0.372 (0.171-0.809), P=0.013] and survival at 6 months [adjusted OR (95%CI)=0.401 (0.190-0.850), P=0.017]. However, when percutaneous coronary intervention or coronary artery bypass grafting (PCI/CABG) was introduced as an adjusted factor, there was a significant association between survival rates and PCI/CABG rather than IABP. In stages D and E of CS, IABP was significantly associated with an improved survival at 1 month [adjusted OR (95%CI)=0.053 (0.012-0.236), P=0.001]. Therefore, IABP could assist patients with stage C of CS in the perioperative period of PCI/CABG and improve survival rates, and IABP might prolong short-term prognosis of patients with stages D and E of CS.

Abstract
Background Parkinson's disease (PD) is a heterogeneous movement disorder with patients manifesting with either tremor-dominant (TD) or postural instability and gait disturbance (PIGD) motor subtypes. Small nerve fiber damage occurs in patients with PD and may predict motor progression, but it is not known whether it differs between patients with different motor subtypes. Objective The aim of this study was to explore whether there was an association between the extent of corneal nerve loss and different motor subtypes. Methods Patients with PD classified as TD, PIGD, or mixed subtype underwent detailed clinical and neurological evaluation and corneal confocal microscopy (CCM). Corneal nerve fiber density (CNFD), corneal nerve branch density (CNBD), and corneal nerve fiber length (CNFL) were compared between groups, and the association between corneal nerve fiber loss and motor subtypes was investigated. Results Of the 73 patients studied, 29 (40%) had TD, 34 (46%) had PIGD, and 10 (14%) had a mixed subtype. CNFD (no./mm2, 24.09 ± 4.58 versus 28.66 ± 4.27; p < 0.001), CNBD (no./mm2, 28.22 ± 11.11 versus 37.37 ± 12.76; p = 0.015), and CNFL (mm/mm2, 13.11 ± 2.79 versus 16.17 ± 2.37; p < 0.001) were significantly lower in the PIGD group compared with the TD group. Multivariate logistic regression showed that higher CNFD (OR = 1.265, p = 0.019) and CNFL (OR = 1.7060, p = 0.003) were significantly associated with the TD motor subtype. The receiver operating characteristic (ROC) analysis demonstrated that combined corneal nerve metrics showed excellent discrimination between TD and PIGD, with an area under the curve (AUC) of 0.832. Conclusion Greater corneal nerve loss occurs in patients with PIGD compared with TD, and patients with a higher CNFD or CNFL were more likely to have the TD subtype. CCM may have clinical utility in differentiating different motor subtypes in PD.

Abstract
Autonomic dysregulation in Parkinson’s disease (PD) can precede motor deficits and is associated with reduced quality of life, disease progression, and increased mortality. Objective markers of autonomic involvement in PD are limited. Corneal confocal microscopy (CCM) is a rapid ophthalmic technique that can quantify small nerve damage in a range of peripheral and autonomic neuropathies. Here we investigated whether CCM can be used to assess autonomic symptoms in PD. Based on the scale for outcomes in Parkinson’s disease for autonomic symptoms (SCOPA-AUT), patients with PD were classified into those without autonomic symptoms (AutD-N), with single (AutD-S), and multiple (AutD-M) domain autonomic dysfunction. Corneal nerve fiber pathology was quantified using CCM, and the relationship with autonomic symptoms was explored. The study enrolled 71 PD patients and 30 control subjects. Corneal nerve fiber density (CNFD), corneal nerve branch density (CNBD), corneal nerve fiber length (CNFL), and CNBD/CNFD ratio were lower in PD patients with autonomic symptoms compared to those without autonomic symptoms. Autonomic symptoms correlated positively with CNFD (r = −0.350, p = 0.004), and were not related to Levodopa equivalent daily dose (r = 0.042, p = 0.733) after adjusting for age, disease severity, disease duration or cognitive function. CCM parameters had high sensitivity and specificity in distinguishing patients with PD with and without autonomic symptoms. PD patients with autonomic symptoms have corneal nerve loss, and CCM could serve as an objective ophthalmic imaging technique to identify patients with PD and autonomic symptoms.

Abstract
The Mn-based superconductor is rare owing to the strong magnetic pair-breaking effect. Here we report on the discovery of pressure-induced superconductivity in KMn_{6}Bi_{5}, which becomes the first ternary Mn-based superconductor. At ambient pressure, the quasi-one-dimensional KMn_{6}Bi_{5} is an antiferromagnetic metal with T_{N}≈75 K. By measuring resistance and ac magnetic susceptibility under hydrostatic pressures up to 14.2 GPa in a cubic anvil cell apparatus, we find that its antiferromagnetic transition can be suppressed completely at a critical pressure of P_{c}≈13 GPa, around which bulk superconductivity emerges and displays a superconducting dome with the maximal T_{c}^{onset}=9.3 K achieved at about 14 GPa. The close proximity of superconductivity to a magnetic instability in the temperature-pressure phase diagram of KMn_{6}Bi_{5} and an unusually large μ_{0}H_{c2}(0) exceeding the Pauli paramagnetic limit suggests an unconventional magnetism-mediated paring mechanism. In contrast to the binary MnP, the flexibility of the crystal structure and chemical compositions in the ternary AMn_{6}Bi_{5} (A=alkali metal) can open a new avenue for finding more Mn-based superconductors.

Abstract
Objective: Systematically summarize the research progress of clinical trials of gastric cancer oncology drugs and the overview of marketed drugs in China from 2012 to 2021, providing data and decision-making evidence for relevant departments. Methods: Based on the registration database of the drug clinical trial registration and information disclosure platform of Food and Drug Administration of China and the data query system of domestic and imported drugs, the information on gastric cancer drug clinical trials, investigational drugs and marketed drugs from January 1, 2012 to December 31, 2021 was analyzed, and the differences between Chinese and foreign enterprises in terms of trial scope, trial phase, treatment lines and drug type, effect and mechanism studies were compared. Results: A total of 114 drug clinical trials related to gastric tumor were registered in China from 2012 to 2021, accounting for 3.7% (114/3 041) of all anticancer drug clinical trials in the same period, the registration number showed a significant growth rate after 2016 and reached its peak with 32 trials in 2020. Among them, 85 (74.6%, 85/114) trials were initiated by Chinese pharmaceutical enterprise. Compared with foreign pharmaceutical enterprise, Chinese pharmaceutical enterprise had higher rates of phase I trials (35.3% vs 6.9%, P=0.001), but the rate of international multicenter trials (11.9% vs 67.9%, P<0.001) was relatively low. There were 76 different drugs involved in relevant clinical trials, of which 65 (85.5%) were targeted drugs. For targeted drugs, HER2 is the most common one (14 types), followed by PD-1 and multi-target VEGER. In the past ten years, 3 of 4 marketed drugs for gastric cancer treatment were domestic and included in the national medical insurance directory. Conclusions: From 2012 to 2021, China has made some progress in drug research and development for gastric carcinoma. However, compared with the serious disease burden, it is still insufficient. Targeted strengthening of research and development of investment in many aspects of gastric cancer drugs, such as new target discovery, matured target excavating, combination drug development and early line therapy promotion, is the key work in the future, especially for domestic companies.

Abstract
Objective: To analyze the thyroid condition and influencing factors of radiation workers, and to provide scientific basis for radiation protection management. Methods: In April 2020, 4308 radiation workers from October 1, 2017 to September 30, 2019 were collected for occupational health examination in Hangzhou Occupational Disease Prevention and Treatment Hospital, the data included basic information, Thyroid hormone level and thyroid color doppler ultrasound results. The thyroid status of radiation workers in different subgroups was compared. The influencing factors of Thyroid nodule were analyzed by multiple logistic regression. Results: 616 radiation workers had abnormal thyroid gland (14.3%, 616/4308) . The main manifestations of thyroid gland abnormality were abnormal Thyroid nodule (5.1%, 220/4308) and abnormal TSH level (7.1%, 308/4308) . Compared with the male radiation workers, the abnormal rate of Thyroid nodule, T3 and Tsh in female radiation workers was higher (P<0.05) , and the abnormal rate of Thyroid nodule, T3 and T4 increased with the increase of working age (P<0.05) . Radiation Workers in non-rated medical institutions and private medical institutions had the highest detection rate of Thyroid nodule (P<0.05) , and there was no significant difference in thyroid abnormalities among Workers (P<0.05) . By multiple logistic regression analysis, Sex (female) , age and institution type (private) were all independent risk factors for Thyroid nodule (95% CI: 1.548~2.763、1.002~1.030, P<0.05) . Conclusion: Ionizing radiation can cause thyroid damage in radiation workers, so we should pay more attention to the radiation protection management of female, high age, private and district medical organizations, so as to protect the health of radiation workers.

Abstract
Cognitive impairment in Parkinson’s disease (PD) adversely influences quality of life. There is currently no available biomarker to predict cognitive decline in PD. Corneal confocal microscopy (CCM) has been used as a non-invasive tool for quantifying small nerve damage in PD. The present study investigated whether corneal nerve measures were associated with cognitive function in PD. Patients with PD were classified into those with normal cognitive function (PD-CN), mild cognitive impairment (PD-MCI), and dementia (PDD). Corneal nerve fiber density (CNFD), corneal nerve branch density (CNBD), and corneal nerve fiber length (CNFL) were quantified with CCM and compared with a control group. Sixty-five PD patients and thirty controls were studied. CNFD was decreased and CNBD was increased in PD patients compared to controls (P < 0.05). CNBD and CNBD/CNFD ratio was higher in PD-CN compared to controls. CNFD was positively correlated with the Montreal cognitive assessment (MoCA) score (r = 0.683, P < 0.001), but negatively associated with unified Parkinson disease rating scale (UPDRS)-part III (r = −0.481, P < 0.001) and total UPDRS scores (r = −0.401, P = 0.001) in PD patients. There was no correlation between CNFD and Levodopa equivalent daily dose (LEDD) (r = 0.176, P = 0.161). CNFD, CNBD, CNFL, and CNBD/CNFD ratio was lower with increasing Hoehn and Yahr stage. PD patients show evidence of corneal nerve loss compared with controls and corneal nerve parameters are associated with the severity of cognitive and motor dysfunction in PD. CCM could serve as an objective in vivo ophthalmic imaging technique to assess neurodegeneration in PD.

Abstract
The vacuum ultraviolet (VUV) radiation is generated in the strong-field-ionized CO molecules through 2+1 resonance excitation with two-color femtosecond laser pulses. When scanning the relative delay between two pump pulses, the rotational-resolved VUV radiations show periodic oscillations lasting as long as 500 ps. Fourier analysis reveals that these oscillations correspond to rotational beat frequencies of the A2Πi state of CO+, which is the result of multi-channel interference during the resonant excitation process. High resolution of Fourier transform spectra up to 0.067cm-1 allows us to obtain the fine energy levels of the A2Πi state. The theoretical calculation is in good agreement with the experimental observation. This work reveals the rotational coherence of the ionic excited state and shows the prospect of rotational coherence spectroscopy in measuring fine structures of molecular ions.

Abstract
We studied the electronic Raman spectra of (Li_{1-x}Fe_{x})OHFeSe as a function of light polarization and temperature. In the B_{1g} spectra alone we observe the redistribution of spectral weight expected for a superconductor and two well-resolved peaks below T_{c}. The nearly resolution-limited peak at 110 cm^{-1} (13.6 meV) is identified as a collective mode. The peak at 190 cm^{-1} (23.6 meV) is presumably another collective mode since the line is symmetric and its energy is significantly below the gap energy observed by single-particle spectroscopies. Given the experimental band structure of (Li_{1-x}Fe_{x})OHFeSe, the most plausible explanations include conventional spin-fluctuation pairing between the electron bands and the incipient hole band and pairing between the hybridized electron bands. The absence of gap features in A_{1g} and B_{2g} symmetry favors the second case. Thus, in spite of various differences between the pnictides and chalcogenides, this Letter demonstrates the proximity of pairing states and the importance of band structure effects in the Fe-based compounds.

Abstract
Objective: To investigate the clinical efficacy of superficial temporal artery -middle cerebral artery combined with encephalo-duro-arterio-myo-synangiosis (STA-MCA+EDAMS) and encephalo-duro-arterio-myo-synangiosis (EDAMS) in the treatment of adult moyamoya disease. Methods: The clinical data of 47 adult patients with moyamoya disease who received vascular reconstruction in the Department of Neurosurgery of Taizhou Hospital of Zhejiang Province from January 2014 to January 2018 were retrospectively analyzed. Among them, 21 patients received EDAMS alone (EDAMS group, 14 patients with hemorrhagic moyamoya disease, 7 patients with ischemic moyamoya disease), 26 patients received STA-MCA combined with EDAMS (STA-MCA+EDAMS group, 17 patients with hemorrhagic moyamoya disease, 9 patients with ischemic moyamoya disease). Cerebral hemodynamics at 1 day before surgery and 3 and 6 months after surgery were compared. The clinical efficacy and postoperative complications of the two methods were compared at 3 and 6 months postoperatively in hemorrhagic and ischemic types. Results: For hemorrhagic moyamoya disease, the remission rate (94.1%) at 6 months after surgery in the STA-MCA + EDAMS group was higher than that in the EDAMS group (57.1%), and the difference was statistically significant (P<0.05). The CBF and CBV in the STA-MCA+EDAMS group were higher than those in the EDAMS group at 3 and 6 months after operation, and the MTT and TPP were lower than those in the EDAMS group, but there was no significant difference between the two groups (all P>0.05). For hemorrhagic moyamoya disease and ischemic moyamoya disease, the total incidence of postoperative complications of the two surgical methods was different, but the difference was not statistically significant (both P>0.05). Conclusion: Superficial temporal artery -middle cerebral artery combined with encephalo-duro- arterio-myo-synangiosis (STA-MCA+EDAMS) and encephalo-duro-arterio-myo-synangiosis (EDAMS) can significantly improve neurological function and cerebral hemodynamics in adult moyamoya disease patients with high safety.

Abstract
Objective: To evaluate the efficacy and safety of DCV-based DAAs therapy for chronic HCV infected Chinese patients. Methods: An open-label, non-randomized, prospective study was designed. Fifty-two patients with chronic HCV infection were enrolled. Among them, there was one patient after liver transplantation, 2 patients after kidney transplantation, 3 patients with hepatocellular carcinoma, and 4 patients with HBV infection. Thirteen cases with chronic hepatitis C (one compensated cirrhosis) who were negative for resistance-related variants [NS5A RAS (-)] of gene 1b and NS5A were treated with daclatasvir (DCV) + asunaprevir (ASV) for 24 weeks. Twenty-five cases of CHC (six compensated cirrhosis) with GT 1b, 2a, 3a, 3b, 6a were treated with DCV + SOF ± RBV for 24 weeks. 8 cases with decompensated cirrhosis of gene 1b and NS5A RAS(-) were given DCV + SOF + RBV regimen for 12 weeks. Six cases with decompensated cirrhosis, of gene 2a, 1b, 2a, 3a, 3b, were given DCV + SOF + RBV regimen for 24 weeks. HCV RNA, blood routine test, liver and kidney function, and upper abdominal ultrasound/MRI were measured at baseline, 4 weeks of treatment, end of treatment, and 12 weeks of follow-up. The incidence of adverse events and laboratory abnormalities during treatment were recorded. A t-test was used to compare the measurement data between two groups, and analysis of variance was used to compare the measurement data between multiple groups. Results: Sixteen patients (100%) achieved SVR12 after treatment, with 0% recurrence rate. Rapid virological response (RVR) of the four treatment regimens were 76.92%, 54.17%, 87.50%, and 83.33%, respectively, and 32 patients achieved 100% virological response after the completion of treatment. The incidence of adverse events of chronic hepatitis C with cirrhosis and decompensated cirrhosis was 62.5% and 64.29%, respectively. The most common adverse event was fatigue in CHC (25.00%), and elevated indirect bilirubin in decompensated cirrhosis (42.86%). No serious adverse drug events, deaths or adverse reactions occurred. Conclusion: DCV-based DAAs regimen is promising option for the treatment of HCV genotypes, compensated cirrhosis, decompensated cirrhosis, hepatocellular carcinoma, and HCV infection after liver/kidney transplantation in china. Above all, it has high SVR12 with good tolerability and safety profile.

Abstract
The lack of high-performance tactile sensors, especially for pressure/force, is a huge obstacle for the widespread application of intelligent robots. Current pressure sensors are often operated in the high range of pressure and normal direction, showing a little ability in the low range of pressure and three-axis direction simultaneously. Herein, a highly sensitive flexible tactile sensor with three-axis force sensing capacity is presented by combining microstructured polydimethylsiloxane (PDMS) arrays and a reduced graphene oxide (rGO) film. The deformation of microstructured rGO/PDMS results in a change in the contact area between the rGO film and electrode, leading to a high sensitivity of -1.71 kPa-1 in the low range pressure of 0-225 Pa with a fast response time of 6 ms at a large feature size of 100 μm. To realize three-axis sensing, a sensing unit was built up, which was composed of the adjacent four parts of patterns and electrodes underneath a bump. A mechanical model of the exerted spatial force was established to calculate each axis force component via the deformation of the rGO/PDMS pattern. The experimental results show that the current difference between the adjacent two parts has a strong relationship with the applied force. As a proof of concept, we have demonstrated a 3 × 3 array sensor for arbitrary force sensing. Our tactile sensor would be used in transmitting information from a gentle spatial force and would exhibit broad applications as e-skin in integrated robots.

Abstract
Objective: To evaluate the population immunity to measles and explore the factors associated with measles susceptibility in Yunnan residents aged ≥20 years. Methods: 2 689 residents aged ≥20 years were selected by multistage stratified systematic randomized sampling in 252 villages of 42 counties in Yunnan Province between June and September in 2015. Each subject was surveyed by the same questionnaire, including general information, measles contained vaccine history, measles history, and 5 ml blood sample of each subject was collected. Serum IgG antibodies against measles virus were measured by ELISA. Positive was defined as the antibody concentration ≥250 mU/ml, and negative as <250 mU/ml. Non-conditional logistic regression model was used analyze the factors associated with measles susceptibility in adults. Results: Among 2 689 subjects, 1 214 were males (45.15%), and the overall positive rate of measles IgG antibody was 89.77%. Compared with subjects from the region where economic development was low, subjects from the region where economic development was moderate were likely to be susceptible to measles virus (OR=1.81, 95%CI: 1.33-2.47). Four age groups had higher risk of being susceptible to measles virus (compared with ≥40 years: 20-24 years old, OR=2.04, 95%CI: 1.26-3.31; 25-29 years old, OR=3.72, 95%CI: 2.37-5.86; 30-34 years old, OR=1.94, 95%CI: 1.22-3.09; 35-39 years old, OR=1.81, 95%CI: 1.07-3.05). Conclusion: Our results suggest that the serological susceptibility in adults (20-39 years), especially adults from the regions where the economic development was moderate, should be concerned. The additional vaccination strategy targeting young adults is important for reducing the risk of measles infection.

Abstract
A novel disease characterized by small brown-black spots (1 to 2 mm in diameter) on tender tea leaves (Camellia sinensis) has been observed in many regions of Hubei Province, China, which severely affects the yield and quality of tea. Tea leaf samples with typical symptoms were collected from three major tea-cultivation regions of Hubei, and were subjected to pathogen isolation for etiological analysis. As a result, 34 Pestalotiopsis isolates were obtained from 20 samples, and they were identified as Pestalotiopsis theae (14 isolates), P. camelliae (12), and P. clavispora (8), determined by morphologies and phylogenetic analysis based on internal transcribed spacer, and partial β-tubulin and translation elongation factor 1-alpha genes. Pathogenicity tests on detached tea leaves showed that no matter what mycelial discs or conidium suspensions were used, inoculation of the Pestalotiopsis fungi could result in small brown-black spots (1 to 2 mm in diameter) on wounded leaves, similar to those observed in the field in the sizes and colors. It also revealed that only P. theae had pathogenicity on unwounded tea leaves, and P. theae and P. clavispora showed significantly higher virulence than P. camelliae. Inoculation test with conidium suspension on intact tea leaves in the field further confirmed that P. theae as the pathogen of brown-black spots. Reisolation of the pathogens from diseased leaves confirmed that the symptom was caused by the inoculation of Pestalotiopsis fungi. The P. theae isolates responsible for brown-black spots were also compared with those for tea gray blight disease in growth rate, pathogenicity, and molecular characteristics in parallel. To our knowledge, this is the first report that the Pestalotiopsis fungi cause brown-black spot disease on tender tea leaves. The results provide important implications for the prevention and management of this economically important disease.

Abstract
RATIONALE Parkinsonism can be secondary to many internal diseases, in some certain conditions, it seems that the clinical manifestations of parkinsonism presenting reversible. We report a case of patient with parkinsonism secondary to pseudohypoparathyroidism, who improved markedly after the supplement of serum calcium. PATIENT CONCERNS AND DIAGNOSES A 52-year-old woman with acute parkinsonism was diagnosed as pseudohypoparathyroidism after the conducting of brain computed tomography, laboratory examinations, and gene detection. The son of the patient was also examined and was diagnosed as pseudohypoparathyroidism, who had ever complained of the history of epilepsy. The clinical manifestations of parkinsonism of the patient was reevaluated after the supplement of serum calcium according to the diagnosis. INTERVENTIONS AND OUTCOMES The brain computed tomography revealed the basal ganglia calcification of the patient, accompanying by serum hypocalcemia and hyperphosphatemia. Loss of function mutation also confirmed the diagnosis. Five days after the therapy targeting at correction of serum hypocalcemia, the patient improved greatly in dyskinesia. LESSONS This study reported a patient presenting as acute reversible parkinsonism, who was finally diagnosed as pseudohypoparathyroidism. It indicated us that secondary parkinsonism should be carefully differentiated for its dramatic treatment effect. And the family history of seizures might be an indicator for the consideration of pseudohypoparathyroidism.

Abstract
OBJECTIVE To compare and analyze the clinical effects of arthroscopic therapy and drug therapy in treating anterior cruciate ligament (ACL) rupture with secondary osteoarthritis (OA). PATIENTS AND METHODS A total of 68 patients that were diagnosed as ACL rupture with secondary OA in our hospital from February 2014 to February 2015 were enrolled in our study. All of the patients were randomly divided into control group (n = 30) and observation group (n = 38) according to the order of admission. The patients in the control group were given analgesic, anti-inflammatory drugs + functional rehabilitation training whereas the patients in the observation group were given ACL reconstruction + OA debridement and functional rehabilitation training under arthroscopy. RESULTS The success rate of the observation group was 92.1%. After 3-month follow-up, the clinical total effective rate of the observation group was significantly higher than that of the control group, the prevalence of complications in the observation group was significantly lower than in the control group, and differences were statistically significant (p < 0.05). Lysholm scale scoring of observation group was significantly higher than of the control group, modified McGill pain scale score was significantly lower than that of the control group, and differences were statistically significant (p < 0.05). Quadriceps muscle peak torque, average power, and the optimal single work at 60°/s, 120°/s, and 180°/s were significantly higher than those of the control group, and differences were statistically significant (p < 0.05). CONCLUSIONS Arthroscopic operative therapy was safe and effective for the treatment of ACL with secondary OA. Compared with drug therapy, it can significantly improve the movement function of the knee joint, so it was worthy of clinical application.

Abstract
Primary small cell carcinoma of the vagina is extremely rare; no standard treatment has been established despite it being highly aggressive. Here, the authors report on a 43-year-old patient who had a mass on the clitoris and no uterine or bilateral adnexal involvement. Vaginal wall biopsy revealed malignant small cell carcinoma. The carcinoma was composed of epithelial cells with round, hyperchromatic nuclei containing few distinct nucleoli, and scanty cytoplasm. Chest computerized axial tomography and pathological bronchoscopy revealed bilateral pulmonary metastases. She received radiotherapy combined with six cycles of chemotherapy (paclitaxel plus cisplatin), and achieved complete response, with complete suppression of the mass and lung metastases. There was no sign of tumor recurrence or distant metastases after 21 months of follow-up.

Abstract
In this work, we develop novel mesoporous silica composite nanoparticles (hm-SiO2(AlC4Pc)@Pd) for the co-delivery of photosensitizer (PS) tetra-substituted carboxyl aluminum phthalocyanine (AlC4Pc) and small Pd nanosheets as a potential dual carrier system to combine photodynamic therapy (PDT) with photothermal therapy (PTT). In the nanocomposite, PS AlC4Pc was covalently conjugated to a mesoporous silica network, and small Pd nanosheets were coated onto the surface of mesoporous silica by both coordination and electrostatic interaction. Since small Pd nanosheets and AlC4Pc display matched maximum absorptions in the 600-800 nm near-infrared (NIR) region, the fabricated hm-SiO2(AlC4Pc)@Pd nanocomposites can generate both singlet oxygen and heat upon 660 nm single continuous wavelength (CW) laser irradiation. In vitro results indicated that the cell-killing efficacy by simultaneous PDT/PTT treatment using hm-SiO2(AlC4Pc)@Pd was higher than PDT or PTT treatment alone after exposure to a 660 nm CW-NIR laser.

Abstract
We examined the association of the interleukin-28B (IL-28B) gene rs12979860 T/C polymorphism with development of hepatitis virus-related hepatocellular carcinoma (HCC) and liver cirrhosis (LC). Two investigators independently searched the PubMed, Elsevier, EMBASE, Web of Science, Wiley Online Library, and Chinese National Knowledge Infrastructure data bases. Pooled odds ratios (ORs) and 95% confidence intervals (95%CIs) for rs12979860 and HCC/LC were calculated in a fixed-effect model (the Mantel-Haenszel method) and a random-effect model (the DerSimonian and Laird method) when appropriate. This meta-analysis included 7 eligible studies, with 1152 HCC and/or LC cases and 1326 controls. Overall, the rs12979860 T/C polymorphism was significantly associated with risk of hepatitis virus-related HCC and LC development (TT vs CC+CT, pooled OR = 1.597, 95%CI = 1.254-2.036). When they were grouped by type of hepatitis virus, similar results were found for hepatitis C virus-related groups (TT vs CC+CT, pooled OR = 1.732, 95%CI = 1.343-2.235, P value < 0.0001). In the overall analysis, the IL-28B rs12979860 T/C polymorphism was identified as a genetic risk factor for hepatitis virus-related HCC and LC development. A significant increase in the frequency of the T/T genotype was detected from chronic hepatitis to HCC and LC.

Abstract
Islet transplantation is the most important approach for treating type I diabetes (T1DM), but the early islet apoptosis limits the therapeutic efficacy. SOCS1 (suppressor of cytokine signaling 1), not only has an effect on cytokine signaling pathway, it is also involved in the regulation of signal transduction pathway in cell apoptosis. The aim of this study was to investigate the effect of overexpression of suppressor of cytokine signaling 1 (SOCS1) in islet grafts. In this paper, the Ad5F35-SOCS1 infected islets were constructed, meanwhile the diabetic mice were established and the xenogenic islet transplantation was performed. After islet transplantation, the blood glucose levels of islet recipients were monitored and the kidney samples were harvested to perform the histological and apoptosis assay. The results showed that the blood glucose was restored in most of the diabetic mice after Ad5F35-SOCS1 infected islets transplantation, and normoglycaemia was maintained for a long time. Furthermore, histological analysis indicated that the infected grafts with overexpression of SOCS1 showed strong insulin secretion function and decreased apoptosis in the early post-transplant period. These results demonstrate that SOCS1 could be the underlying target molecule in islet therapy which has great clinical and practical significance.

Abstract
Objective To describe clinical features of patients with multiple sclerosis (MS) in Shanghai, China. Methods Prevalent patients with MS were identified and investigated by a network of physicians in 11 districts of Shanghai during the period from 1 September 2004 to 31 August 2005. Admission registries of each hospital in the study area were checked systematically for patients with a diagnosis of MS, neuromyelitis optica or other demyelinating disorders. All patients with collected information were evaluated by four senior neurologists according to the McDonald criteria. Results There were 249 (146 female and 103 male) patients with a confirmed MS diagnosis, at a female-to-male ratio of 1.4. The mean age at onset of MS was 37.4 years for the 249 patients with MS and, on the prevalence day, 42.7 years. The most frequent location of clinical MS lesions in the central nervous system was the spinal cord (61%), followed by the cerebrum (55%) and optic nerves (41%). Nearly all (96%) of the patients with MS had been examined by magnetic resonance imaging, and 226 (94%) patients of those examined were suggestive of MS. No family history of MS was found in any of the patients. Most (86%) of the patients had no or mild disability on the prevalence day (31 December 2004). Almost all (96%) patients with MS had been treated with corticosteroids. Conclusion Clinical features of patients with MS are described based on the information from the largest case series reported among Chinese. Comparisons and discussions are made with findings from the other populations.

Abstract
Two or eight zinc triphenyl porphyrins were conjugated with Zn-phthalocyanine or H2-phthalocyanine to form ZnPc-(ZnTPP)2, ZnPc-(ZnTPP)8, H2Pc-(ZnTPP)2 and H2Pc-(ZnTPP)8. Energy transfers from the porphyrin moiety to phthalocyanine part were quantitatively studied with the modality of fluorescence resonance energy transfer (FRET). By measuring the fluorescence increment from the phthalocyanine moiety and the decrease from porphyrin part under selective excitation at the B band of the porphyrin part in those conjugated compounds and their equimolar mixture of compositions, energy transfer efficiencies were estimated to be 90% for H2Pc-(ZnTPP)8 and ZnPc-(ZnTPP)8, and 60%, 30% for ZnPc-(ZnTPP)2 and H2Pc-(ZnTPP)2, respectively.

Abstract
High resolution angle-resolved photoemission spectroscopy data along the (0,0)-(pi,pi) nodal direction with significantly improved statistics reveal fine structure in the electron self-energy of the underdoped (La2-xSrx)CuO4 samples in the normal state. Fine structure at energies of (40-46) meV and (58-63) meV, and possible fine structure at energies of (23-29) meV and (75-85) meV, have been identified. These observations indicate that, in (La2-xSrx)CuO4, more than one bosonic modes are involved in the coupling with electrons.

Abstract
A simple and sensitive electrochemical immunosensor with impedance labelless detection and novel data processing method was investigated. One-step copolymerization was used to electrochemically deposit an antibody impregnated polypyrrole film on a glassy carbon electrode surface for the immunosensor. Impedance measurements provided a labelless or reporterless method to detect antibody (Ab)-antigen (Ag) interactions. Dimensionless analysis was employed to successfully process the measured impedance data. Since the method derived unit impedance change to eliminate or reduce the variation of the bulk electronic properties of Ab/polypyrrole films, the signal to noise ratio (S/N) was significantly improved for high sensitivity and specificity. Nonspecific binding effect was studied by array electrode chips and was found out that the polypyrrole electrode without antibody attachment had much stronger nonspecific binding effect than the Ab/polypyrrole electrode; incubation followed by thoroughly washing significantly reduced the nonspecific interference. 10 pg/ml detection limit and superior specificity were achieved by the method, demonstrating a highly sensitive labelless immunosensor in comparison with the detection limit of ng -microgram/ml for the reported polypyrrole based immunosensors. The electrochemical immunosensors presented in this paper, due to its simplicity, low cost, high sensitivity and superior specificity, could be an invaluable tool for clinical diagnostics and could have potential applications in drug discovery, environmental and food analysis.

Abstract
High resolution angle-resolved photoemission measurements on an underdoped (La(2-x)Srx)CuO4 system show that, at energies below 70 meV, the quasiparticle peak is well defined around the (pi/2,pi/2) nodal region and disappears rather abruptly when the momentum is changed from the nodal point to the (pi,0) antinodal point along the underlying "Fermi surface." It indicates that there is an extra low energy scattering mechanism acting upon the antinodal quasiparticles. We propose that this mechanism is the scattering of quasiparticles across the nearly parallel segments of the Fermi surface near the antinodes.

Abstract
The kinetic energy distribution of D+ ions resulting from the interaction of a femtosecond laser pulse with D2 molecules is calculated based on the rescattering model. From analyzing the molecular dynamics, it is shown that the recollision time between the ionized electron and the D+2 ion can be read from the D+ kinetic energy peaks to attosecond accuracy. We further suggest that a more precise reading of the clock can be achieved by using shorter fs laser pulses (about 15 fs).

Abstract
The electrical transport properties of epitaxial superconducting Bi(2+y)Sr(2-x-y)La(x)CuO(6+delta) thin films have been studied in magnetic fields. Using a modified Coulomb-gas scaling law, we can fit all the magnetic field dependent low resistance data with a universal scaling curve, which allows us to determine a relation between the activation energy of the thermally activated flux flow resistance and the characteristic temperature scaling parameters.

Abstract
An incommensurate modulation has been observed in a Cu-rich La2CuO4.003 crystal. It is shown that the modulation results from a periodically distributed holes lying on the CuO2 planes, and that the hole modulation may be regarded to be a kind of valence modulation. It is shown that appreciable valence modulation contrast may be generated by the mechanisms of hole scattering alone when the period of the modulation is of the order of 2 nm.

Abstract
By measuring the superconducting diamagnetic moments for an underdoped and an overdoped La2-xSrxCuO4 single crystal with equal quality and roughly equal transition temperatures, it is found that the underdoped sample has only one transition which corresponds to H(c2), but the overdoped sample has two transitions with the higher one at H(c2). Further investigation reveals the same upper-critical field H(c2) for both samples although the overall charge densities are very different, indicating the possibility of a very direct and detailed equivalence of the superconducting condensation process in the two doping limits. The second transition for the overdoped sample can be understood as the bulk coupling between the superconducting clusters produced by macroscopic phase separation.

Abstract
Crebanine (Cre) iv 5 mg/kg could convert BaCl2-induced arrhythmia into sinus rhythm in rats, and could significantly increase the tolerant dose of aconitine to produce ventricular fibrillation (VF) and cardiac arrest (CA) in rats. The drug could also decrease the incidence of VF and CA by CaCl2 in rats and by chloroform in mice, but had no protective effects on ouabain-induced arrhythmias in guinea pigs.
