Abstract
Objective: To explore the relationship between gut microbiota and its metabolite dysregulation and postoperative cognitive dysfunction in elderly male C57BL/6J mice after laparotomy exploration. Methods: A total of 48 specific pathogen-free (SPF) male C57BL/6J mice, aged 16-17 months, were divided into two groups by random number table method: control group (n=24) and operation group (n=24). Mice in the operation group were induced with 1.4% isoflurane for 15 minutes, followed by a 10 minutes exploratory laparotomy anesthetized with 1.4% isoflurane and 100% oxygen, and anesthesia continued for 2 hours after surgery. Mice in control group were put in 100% oxygen for 2 hours. Feces and venous blood samples of both groups were collected 48 hours after surgery. Changes in the abundance and diversity of intestinal bacteria in the feces were detected by 16S rDNA gene sequencing. Functional changes of fecal metabolic profiles were detected by liquid chromatography tandem mass spectrometry (LC/MS) metabolomics and differential metabolite functions were analyzed. The serum level of interleukin (IL)-6, IL-1β and tumor necrosis factor-α (TNF-α) were detected by Enzyme-linked immunosorbent assay (ELISA). The cognitive function of the mice was detected by Morris water maze test 3 days after operation. Results: The postoperative escape latency of mice in control group and operation group was (22.0±4.9) and (35.0±5.1) s, and the target quadrant residence time was (26.0±3.7) and (16.0±2.9) s, respectively. Compared with the control group, the postoperative escape latency of mice in the operation group was prolonged (P=0.035), and the residence time in the target quadrant was reduced (P=0.006). The difference of intestinal flora between the two groups was comparable. The expression levels of Escherichia coli, shigella and clostridium in the operation group were up-regulated, while the expression levels of rumen bacteria and butyricobacteria were down-regulated. Fecal metabolic profiles of mice in control group and operation group were obtained by LC/MS, and 14 and 21 different metabolites were screened in positive and negative ion modes, respectively. The different metabolites in positive ion mode were glutamic acid, 2-indoleic acid, kynuuric acid and glyceraldehyde. The negative ion pattern differential metabolites are methionine, aspartic acid, L-threonine, tyrosyl-threonine and 5-hydroxyindole-3-acetic acid. The identified differential metabolite pathways are mainly involved in amino acid, fatty acid and tryptophan metabolism and nucleotide synthesis. There were no significant differences in serum levels of IL-1β, IL-6 and TNF-α between the two groups (all P>0.05). Conclusion: The dysregulated changes of gut microbiota and its metabolites are correlated with the occurrence of postoperative cognitive dysfunction in elderly male C57BL/6J mice. Anesthesia and surgery alter the structure of mice intestinal bacteria on the level of abundance, and change the metabolic balance and feces metabolomic phenotype.

Abstract
Objective: To investigate the effect of deep neuromuscular blockade (DNMB) combined with low pneumoperitoneum pressure anesthesia strategy on postoperative pain in patients undergoing laparoscopic colorectal surgery. Methods: This study was a randomized controlled trial. One hundred and twenty patients who underwent laparoscopic colorectal surgery at Cancer Hospital of Chinese Academy of Medical Sciences from December 1, 2022 to May 31, 2023 were selected and randomly divided into two groups by random number table method. Moderate neuromuscular blockade [train of four stimulations count (TOFC)=1-2] was maintained in patients of the control group (group C, n=60) and pneumoperitoneum pressure level was set at 15 mmHg(1 mmHg=0.133 kPa). DNMB [post-tonic stimulation count (PTC)=1-2] was maintained in patients of the DNMB combined with low pneumoperitoneum pressuregroup (group D, n=60) and pneumoperitoneum pressure level was set at 10 mmHg. The primary measurement was incidence of moderate to severe pain at 1 h after surgery. The secondary measurements the included incidence of moderate to severe pain at 1, 2, 3, 5 d and 3 months after surgery, the incidence of rescue analgesic drug use, the doses of sufentanil in analgesic pumps, surgical rating scale (SRS) score, the incidence of postoperative residual neuromuscular block, postoperative recovery [evaluated with length of post anesthesia care unit (PACU) stay, time of first exhaust and defecation after surgery and length of hospital stay] and postoperative inflammation conditions [evaluated with serum concentration of interleukin (IL)-1β and IL-6 at 1 d and 3 d after surgery]. Results: The incidence of moderate to severe pain in group D 1 h after surgery was 13.3% (8/60), lower than 30.0% (18/60) of group C (P<0.05). The incidence of rescue analgesia in group D at 1 h and 1 d after surgery were 13.3% (8/60) and 4.2% (5/120), respectively, lower than 30.0% (18/60) and 12.5% (15/120) of group C (both P<0.05). The IL-1β level in group D was (4.1±1.8)ng/L at 1 d after surgery, which was lower than (4.9±2.6) ng/L of group C (P=0.048). The IL-6 level in group D was (2.0±0.7)ng/L at 3 d after surgery, which was lower than (2.4±1.1) ng/L of group C (P=0.018). There was no significant difference in the doses of sufentanil in analgesic pumps, intraoperative SRS score, incidence of neuromuscular block residue, time spent in PACU, time of first exhaust and defecation after surgery, incidence of nausea and vomiting, and length of hospitalization between the two groups (all P>0.05). Conclusion: DNMB combined with low pneumoperitoneum pressure anesthesia strategy alleviates the early-stage pain in patients after laparoscopic colorectal surgery.

Abstract
Spin-dependent transport in ferromagnet/organic-ferromagnet/ferromagnet junctions is investigated theoretically under different alignment of magnetization orientations. The results demonstrate a significant current rectification at low bias voltages, and the rectifying direction relies on the relative magnetization orientation in each component. The orbital analysis demonstrates two underlying mechanisms for the rectification, the slight structural asymmetry of the molecule from spin radicals and distinct spin match between conducting electrons and the magnetic molecule upon the reversal of bias. The latter is responsible for the strong low-bias rectification and relies on the magnetization alignment. The effects of parameter strength, temperature and size on the rectification are discussed. This work explores a new route to achieve high-performance molecular rectifiers operating at low bias with controlled rectifying direction.

Abstract
The intertwining between spin, charge, and lattice degrees of freedom can give rise to unusual macroscopic quantum states, including high-temperature superconductivity and quantum anomalous Hall effects. Recently, a charge density wave (CDW) has been observed in the kagome antiferromagnet FeGe, indicative of possible intertwining physics. An outstanding question is that whether magnetic correlation is fundamental for the spontaneous spatial symmetry breaking orders. Here, utilizing elastic and high-resolution inelastic x-ray scattering, we observe a c-axis superlattice vector that coexists with the 2[Formula: see text]2[Formula: see text]1 CDW vectors in the kagome plane. Most interestingly, between the magnetic and CDW transition temperatures, the phonon dynamical structure factor shows a giant phonon-energy hardening and a substantial phonon linewidth broadening near the c-axis wavevectors, both signaling the spin-phonon coupling. By first principles and model calculations, we show that both the static spin polarization and dynamic spin excitations intertwine with the phonon to drive the spatial symmetry breaking in FeGe.

Abstract
Objective: To investigate the clinicopathological features, diagnosis and differential diagnosis of breast myofibroblastoma. Methods: The clinicopathological data and prognostic information of 15 patients with breast myofibroblastoma diagnosed at the Department of Pathology of the First Affiliated Hospital of Zhengzhou University, Zhengzhou, China from 2014 to 2022 were collected. Their clinical characteristics, histological subtypes, immunophenotypes and molecular characteristics were analyzed. Results: There were 12 female and 3 male patients, ranging in age from 18 to 78 years, with a median and average age of 52 years. There were 6 cases in the left breast and 9 cases in the right breast, including 12 cases in outer upper quadrant, 2 cases in inner upper quadrant and 1 case in outer lower quadrant. Most of the cases showed a well-defined nodule grossly, including pushing growth under the microscope in 13 cases, being completely separated from the surrounding breast tissue in 1 case, and infiltrating growth in 1 case. Among them, 12 cases were classic subtype and composed of occasional spindle cells with varying intervals of collagen fiber bundles; eight cases had a small amount of fat; one case had focal cartilage differentiation; one case was epithelioid subtype, in which epithelioid tumor cells were scattered in single filing or small clusters; one case was schwannoma-like subtype, and the tumor cells were arranged in a significant palisade shape, resembling schwannoma, and one case was invasive leiomyoma-like subtype, in which the tumor cells had eosinophilic cytoplasm and were arranged in bundles, and infiltrating into the surrounding mammary lobules like leiomyoma. Immunohistochemical studies showed that the tumor cells expressed desmin (14/15) and CD34 (14/15), as well as ER (15/15) and PR (15/15). Three cases with histologic subtypes of epithelioid subtype, schwannoma-like subtype and infiltrating leiomyoma-like subtype showed RB1 negative immunohistochemistry. Then FISH was performed to detect RB1/13q14 gene deletion, and identified RB1 gene deletion in all three cases. Fifteen cases were followed up for 2-100 months, and no recurrence was noted. Conclusions: Myofibroblastoma is a rare benign mesenchymal tumor of the breast. In addition to the classic type, there are many histological variants, among which the epithelioid subtype is easily confused with invasive lobular carcinoma. The schwannoma-like subtype is similar to schwannoma, while the invasive subtype is easily misdiagnosed as fibromatosis-like or spindle cell metaplastic carcinoma. Therefore, it is important to recognize the various histological subtypes and clinicopathological features of the tumor for making correct pathological diagnosis and rational clinical treatment.

Abstract
Objective: To analyze the risk factors of polymyositis/dermatomyositis (PM/DM) complicated with malignant tumor and to construct clinical prediction model. Methods: A total of 427 PM/DM patients, who were admitted to Rheumatism Immunity Branch, the Second Affiliated Hospital, Air Force Medical University from January 1, 2015 to January 1, 2021, were enrolled in the study, including 129 males and 298 females. The mean age was (51.4±12.2) years. The patients were divided into control group (without malignant tumor, n=379) and case group (with malignant tumor, n=48) according to whether they were complicated with malignant tumors. In the two groups, 70% of the patients' clinical data were randomly selected as the training set data, and the remaining 30% were used as the validation set data. The clinical parameters were retrospectively collected, and risk factors of PM/DM complicated with malignant tumor were analyzed by binary logistic regression. R software was used to construct a clinical prediction model for malignant tumors in PM/DM patients using training set data. Validation set data were used to assess the feasibility of the model. The area under the receiver operating characteristic (ROC) curve (AUC), calibration curve and decision curve analysis (DCA) were used to evaluate the predictive ability, accuracy and clinical applicability of the nomogram model. Results: The age of the control group was (50.4±11.8) years, and males accounted for 26.9%(102/379); the age of the case group was (59.1±12.7) years, and the proportion of males was 56.3% (27/48). The proportion of male, age, the positive rate of anti-transcription mediator 1-γ (TIF1-γ) antibody, glucocorticoid therapy resistance, and levels of creatine kinase (CK), carbohydrate antigen 125(CA125) and carbohydrate antigen 199 (CA199) were all higher in the case group than those in control group, while incidence of interstitial lung disease (ILD), arthralgia, Raynaud's phenomenon, serum albumin (ALB) level and lymphocyte (LYM) count were all lower than those in control group (all P<0.05). Binary logistic regression analysis showed that male (OR=2.931, 95%CI: 1.356-6.335), glucocorticoid therapy resistance (OR=5.261, 95%CI: 2.212-12.513), older age (OR=1.056, 95%CI: 1.022-1.091), elevated CA125 (OR=8.327, 95%CI: 2.448-28.319) and positive anti-TIF1-γ antibody (OR=7.529, 95%CI: 2.436-23.270) were risk factors of malignancy in PM/DM patients (all P<0.05); and complicated with ILD (OR=0.261, 95%CI: 0.099-0.689), complicated with arthralgia (OR=0.238,95%CI:0.073-0.779), elevated LYM count (OR=0.267, 95%CI: 0.103-0.691) were protective factors of malignancy in PM/DM patients (all P<0.05). The AUC of ROC curve predicting malignancy in PM/DM patients with the training concentrated prediction model was 0.887 (95%CI: 0.852-0.922), with a sensitivity of 77.9% and a specificity of 86.3%; it was 0.925 (95%CI: 0.890-0.960), 86.5% and 88.0% in the validated centralized prediction model, respectively. The correction curves of the training set and the validation set indicated that the predictive model had good calibration ability. Both the DCA curves of the training set and the validation set showed that the proposed predictive model had good clinical applicability. Conclusions: Older age, male, glucocorticoid therapy resistance, not complicated with ILD and arthralgia, elevated CA125, positive anti-TIF1-γ antibody, decreased LYM count are risk factors for malignancy in PM/DM patients, and the established nomogram model shows good predictive ability.

Abstract
CDC25B belongs to the CDC25 family, and it plays an important part in regulating the activity of CDK/CyclinA. Studies have shown that CDC25B is closely related to cancer development. When CYS473 on CDC25B is mutated into ASP, the affinity between CDC25B and CDK2/CyclinA weakens, and their dissociation speed is greatly improved. However, the mechanism by which the CDC25BC473D mutant weakens its binding to CDK2/CyclinA is unclear. In order to study the effect of CDC25BC473D mutants on CDK2/CyclinA substrates, we constructed and verified the rationality of the CDC25BWT:CDK2/CyclinA system and CDC25BC473D:CDK2/CyclinA system and conducted molecular dynamics (MD) simulation analysis. In the post-analysis, the fluctuations of residues ARG488-SER499, LYS541-TRP550 on CDC25B and residues ASP206-ASP210 on CDK2 were massive in the mutant CDC25BC473D:CDK2/CyclinA system. And the interactions between residue ARG492 and residue GLU208, residue ARG544 and residue GLU42, residue ARG544 and TRP550 were weakened in the mutant CDC25BC473D:CDK2/CyclinA system. The results showed that when CYS473 on CDC25B was mutated into ASP473, the mutant CDC25BC473D:CDK2/CyclinA system was less stable than the wild-type CDC25BWT:CDK2/CyclinA system. Finally, active site CYS473 of CDC25B was speculated to be the key residue, which had great effects on the binding between CDC25BCYS473 and CDK2 in the CDC25BC473D:CDK2/CyclinA system. Consequently, overall analyses appeared in this study ultimately provided a useful understanding of the weak interactions between CDC25BCYS473D and CDK2/CyclinA.Communicated by Ramaswamy H. Sarma.

Abstract
Hyperalgesia is an occult complication during the treatment of cancer pain, not only related to opioids, but also pertaining to the tumor itself and cancer therapeutic drugs. Yet it is often ignored by clinicians. Patients with cancer pain who were treated with opioids often have sensory abnormalities presented with reduced pain threshold and increased sensitivity to nociceptive stimuli. This phenomenon is clinically called opioid-induced hyperalgesia (OIH). However, due to the complexity of pathogenesis and the lack of clinical diagnostic criteria, the pain management of cancer patients is still facing great challenges. Therefore, this article focuses on the clinical diagnosis, pathogenesis, prevention and treatment of hyperalgesia related to cancer pain treatment, in order to provide a basis for optimal use of opioids in the future.

Abstract
Objective: To assess whether myocardial fibrosis affects the protective efficiency of ischemic preconditioning (IPC) against myocardial ischemia/reperfusion injury (MIRI) in type 2 diabetic rats. Methods: Type 2 diabetic rat model was established. Fifty-four normal and 54 diabetic spragus-dawley (SD) rats were equally divided into 6 groups (n=18) using the random number table method: (1) Control group (C group); (2) Ischemia reperfusion injury (IRI) control group (IRI group); (3) IPC group; (4) Diabetic control group (DC group); (5) Diabetic IRI group (DIRI group); (6) Diabetic IPC group (DIPC group). After the reperfusion, blood samples were obtained for measuring serum concentrations of creatine kinase-MB (CK-MB) and cardiac troponin I (cTnI) using enzyme-linked immunosorbent assay (ELISA). The myocardial infarction size (IS) was assessed by double staining method with Evan's blue and Triphenyl tetrazolium chloride (TTC), and the myocardial collagen volume fraction (CVF) and perivascular collagen area (PVCA) were assessed by Masson staining. Results: A stable and effective rat model with long-term diabetes was established in the current study. Compared with the normal rat groups, the CVF and PVCA significantly increased (all P<0.05) in the diabetic rat groups. The levels of CK-MB, cTnI and IS in the IPC group were (6.6±0.8) ng/ml, (0.5±0.1) ng/ml and (25.1±4.7) %, which showed significant decrease compared with (12.3±1.1) ng/ml, (1.2±0.3) ng/ml and (52.3±8.1) % in IRI group (all P<0.05). Among the diabetic rat groups, the CK-MB and cTnI levels in DIPC group were (11.5±0.9) and (1.1±0.1) ng/ml, apparently lower than the levels of (16.6±2.2) and (1.4±0.3) ng/ml in the DIRI group (both P<0.05). Compared with the IPC group, the IS, CK-MB and cTnI levels significantly increased in the DIPC group (all P<0.05). Conclusion: Myocardial fibrosis exists in rats with long-term type 2 diabetes, which weakens the protective effect of IPC on diabetes MIRI.

Abstract
Cell division cycle 25B (CDC25B) was responsible for regulating the various stages of cell division in the cell cycle. R492L was one of the common types of CDC25B mutants. Researches showed that compared to CDC25BWT, CDC25BR492L mutant had a ∼100-fold reduction in the rate constant for forming phosphatase intermediate (k2). However, the molecular basis of how the CDC25BR492L mutant influenced the process of binding between CDC25B and CDK2/CyclinA was not yet known. Therefore, the optimizations of three-dimensional structure of the CDC25BWT-CDK2/CyclinA system and the CDC25BR492L-CDK2/CyclinA system were constructed by ZDOCK and RDOCK, and five methods were employed to verify the reasonability of the docking structure. Then the molecular dynamics simulations on the two systems were performed to explore the reason why CDC25BR492L mutant caused the weak interactions between CDC25BR492L and CDK2/CyclinA, respectively. The remote docking site (Arg488-Tyr497) and the second active site (Lys538-Arg544) of CDC25B were observed to have high fluctuations in the CDC25BR492L-CDK2/CyclinA system with post-analysis, where the high fluctuation of these two regions resulted in weak interactions between CD25B and CDK2. In addition, Asp38-Glu42 and Asp206-Asp210 of CDK2 showed the slightly descending fluctuation, and CDK2 revealed an enhanced the self-interaction, which made CDK2 keep a relatively stable state in the CDC25BR492L-CDK2/CyclinA system. Finally, Leu492 of CDC25B was speculated to be the key residue, which had great effects on the binding between CDC25BR492L and CDK2 in the CDC25BR492L-CDK2/CyclinA system. Consequently, overall analyses appeared in this study ultimately offered a helpful understanding of the weak interactions between CDC25BR492L and CDK2.

Abstract
Objective: To explore the method and plausibility of using free rectus abdominis flap (FRAF) to reconstruct the major and complex defects in the craniofacial regions after ablation of advanced sinonasal carcinoma. Methods: From 2007 to 2018 at No. 980 Hospital of Joint Logistic Supportive Force of People's Liberation Army of China, 13 patients with advanced carcinoma of nasal cavity and paranasal sinuses, including 11 males and 2 females, aged from 33 to 67 years, were treated with FRAF to repair the invasion of skull base, face and orbit. Based on adequate and meticulous preoperative evaluations on patients and tumors, complete resection of tumor bulks was performed. According to the sites, characters and extents of the defects, FRAF was introduced in different ways into reconstruction of major and complex defects in the craniofacial regions after resection of advanced sinonasal carcinomas, restoring the structure and contour of the craniofacial region. Results: Complete resection of tumors was achieved in all cases. For repairing the major and complex defects resulted from tumor ablation, FRAF graft was conducted in 13 patients with advanced sinonasal carcinomas. The recipient vessels were facial artery and vein in 9 cases, superficial temporal artery and vein in 4 cases. Vascular bridging with the external jugular vein was carried out in 2 cases who underwent submandibular neck dissections, in which facial artery and vein were used as recipient vessels. Free fibular flap was used along with FRAF in a case undergone bilateral maxillectomy. Pedicled galea capitis and periosteal flap were applied simultaneously in 3 cases with dura defects at the skullbase resulted from tumor resection. All flaps used in 13 cases survived uneventfully without major complications, with successful repair of defects, reconstruction of structures and restoration of contour of craniofacial regions. Conclusion: With adequate evaluation of resectability of tumors as well as nature and extent of defects after tumor removal, FRAF transplantation is an ideal method and strategy of choice for reconstructing the major and complex defects in craniofacial regions resulted from tumor ablation of advanced sinonasal carcinomas.

Abstract
To investigate whether the laboratory specimens preserved in Beijing Hospital Biobank during a specific period had been contaminated by SARS-Cov-2 through a cross-sectional study, and to establish a retrospective biobank safety screening system. Laboratory specimens were collected from the Department of Respiratory and Critical Care Medicine and the Fever Clinic of Beijing Hospital from November 1, 2019 to January 22, 2020, nucleic acid and serological antibody testing were performed for SARS-CoV-2 in these specimens (including 79 serum, 20 urine, 42 feces and 21 bronchoalveolar lavage fluid specimens). The safety of the stored samples during this period was defined by negative and positive results. Both the nucleic acid test and serological antibody test showed negative for SARS-CoV-2, indicating that these specimens were safely stored in the biobank. High-risk specimens collected in our hospital during the early stage of the COVID-19 outbreak are free of SARS-CoV-2, and a safety screening strategy for the clinical biobank is established to ensure the biosafety of these samples.

Abstract
Objectives: To examine the prognosis factors of recurrence of esophageal carcinoma within 6 months after neoadjuvant therapy followd by surgery. Methods: The clinical data of 187 patients with esophageal squamous cell carcinoma who underwent neoadjuvant therapy followed by curative esophagectomy between January 2018 and April 2020 at Department of Thoracic Surgery, Shanghai Chest Hospital were analyzed retrospectively. There were 160 males and 27 females, aging (63.0±7.1) years (range:43 to 76 years). The t test, χ2 test and rank-sum test were used for univariate analysis of the prognosis factors for recurrence within 6 months postoperative, while the Logistic regression was used for multivariate analysis. Results: There were 30 patients (16.0%) developed recurrence within 6 months after operation, including local recurrence in 1 case, regional recurrence in 11 cases, hematogenous recurrence in 13 cases, and combined recurrence in 5 cases. Univariate analysis suggested that there was a significant difference in T staging of tumor before neoadjuvant therapy (cT), tumor regression grade, circumferential resection margin, pathological T stage (ypT) and pathological N stage (ypN) between the recurrence patients and non-recurrence patients (all P<0.05). Logistic regression analysis suggested that the cT3-4 (OR=2.701, 95%CI: 1.161 to 6.329, P=0.021) and ypN(+)(OR=1.654, 95%CI: 1.045 to 2.591, P=0.032) were the independent prognosis factors for recurrence within 6 months. Conclusion: The combination of neoadjuvant therapy and surgery is not effective in reducing early postoperative recurrence in patients who have invaded the epineurium before treatment, and still have positive lymph nodes after neoadjuvant therapy.

Abstract
Objective: To investigate the effects of duodenal ligation on gastroesophageal reflux and bleomycin-induced pulmonary fibrosis in rats. Methods: Wistar rats were randomized into the control (Ctrl) group, bleomycin (BLM) group, duodenal ligation (GER) group and duodenal ligation plus bleomycin treatment (BLM+GER) group. At day 0 (d0), duodenum ligation was performed in the GER and the BLM+GER group through an open-abdomen surgery at 1.0 cm below the pylorus by about 30% of the circumference. Meanwhile, sham operation was performed in the Ctrl and the BLM group with similar procedures to the above without ligation of the duodenum. At day 14, bleomycin solution (5 mg/kg, for the BLM and BLM+GER groups) or saline (for the Ctrl and GER groups) was intratracheally instilled. Rats were sacrificed at d28 or at d42. HE, Masson's trichrome or TUNEL staining was performed on lung sections of the groups. The levels of hyrdoxyproline (HYP) or malondialdehyde (MDA) were measured respectively by alkaline hydrolysis or thiobarbituric acid colorimetry. The levels of pepsin and cytokines in bronchoalveolar lavage fluid (BALF) samples were assessed by ELISA. Western blot or RT-PCR was used to quantify relative lung expression of proteins or mRNA, respectively. Results: Lungs of the GER group rats were presented with mild inflammatory cell infiltration. Alveolitis and lung fibrosis was prominent in the BLM group but even more severe in the BLM+GER group. Of the Ctrl, GER, BLM and BLM+GER group, the average numbers of apoptotic cells per each magnified field (×200) on d28 lung sections was (5.6±3.0), (6.4±5.3), (15.4±5.3) and (18.4±9.1), respectively (P=0.008); the proportion (%) of blue-stained area under Masson's trichrome at d42 was (21.5±2.8), (23.4±2.5), (34.0±5.8) and (41.3±2.9) (P<0.05); the HYP contents (mg/L) at d42 of each group was (0.77±0.01), (1.26±0.01), (2.02±0.01) and (2.39±0.01) (P<0.01); the BALF levels of MDA (μmol/L) at d42 were (0.51±0.09), (0.87±0.12), (1.40±0.31) and (1.71±0.12) (P<0.001), and differences of these three indices at d42 reached statistical significance when comparing the Ctrl or GER group with the BLM or BLM+GER group (all P<0.05). The levels of pepsin, pH, interleukin (IL)-1β, transforming growth factor (TGF)-β1 and HYP at d28 and d42 were statistically different between the GER group and the Ctrl group (all P<0.05). As compared with the BLM group, the values of TGF-β1, HYP, p-Smad3, vimentin, p-ERK1/2 and cleaved caspase-3 at d28 and d42 were different in the BLM+GER group (all P<0.05). At both d28 and d42, the BALF levels of pepsin and pH were statistically different between the BLM and the Ctrl group, or between the BLM+GER group and the GER group (all P<0.05). Conclusions: Gastroesophageal reflux is induced through duodenal ligation, which activates proinflammatory and profibrotic signals in the lungs and significantly aggravates bleomycin-induced lung injury and fibrosis. In addition, pulmonary fibrosis may induce or worsen the extent of reflux.

Abstract
PURPOSE To evaluate the changes in ocular biomechanical properties in active moderate-to-severe Graves' orbitopathy (GO) after intravenous glucocorticoids (IVGCs), and to clarify correlations between clinical findings and ocular biomechanical properties. METHODS A prospective study. A total of 20 consecutive GO patients and 20 age- and sex-matched healthy control subjects were included. GO was diagnosed on the basis of the recommendation by the European Group on Graves' Orbitopathy (EUGOGO), and disease activity was assessed by the clinical activity score (CAS). Patients were assigned to receive once weekly IVGCs (0.5 g, then 0.25 g, 6 weeks each). All participants received a full ophthalmic examination and biomechanical evaluation was performed with dynamic Scheimpflug analyzer (Corvis ST) at baseline and 12th weeks after therapy. RESULTS The biomechanically corrected intraocular pressure (bIOP) in GO patients was significantly higher than that in healthy subjects. In contrast, the whole eye movement (WEM) in GO patients was significantly lower than in healthy subjects after adjusting for bIOP. The CAS, NOSPECS score, and exophthalmos were significantly positively correlated with the bIOP and negatively correlated with the WEM after adjusting for bIOP, CCT and age. The WEM significantly increased, whereas bIOP significantly decreased after IVGCs (P < 0.001, P = 0.001 respectively). The overall response rate at the 12th week was 85% (17 of 20). CONCLUSIONS The changes of ocular biomechanical properties measured by Corvis ST were an objective indicator of inflammatory activity and severity of GO. Combining CAS and ocular biomechanical properties could better evaluate the therapeutic outcome of active moderate-to-severe GO.

Abstract
Objective: To explore the clinical phenotypic characteristics of coal worker's pneumoconiosis for guiding the individualized treatment of various types of patients with coal worker's pneumoconiosis. Methods: Collect clinical data of 121 cases of coal worker's pneumoconiosis in different stages, and select 16 clinical variables (age, smoking index, years of underground dust exposure, stages of pneumoconiosis, types of work, family history, main symptoms, secondary symptoms, CAT score, imaging manifestations, FVC%, FEV(1)/FVC, FEV(1)%, DLCO%, respiratory failure complications, pulmonary heart disease complications) . Principal Component Factor Analysis (PCA) was used to analyze 16 clinical variables of 121 patients with coal worker's pneumoconiosis. Extracted 2 principal components and 8 related variables from 16 clinical variables, then coal worker's pneumoconiosis patients were divided into three types according to CCC values. Variance analysis or χ(2) test were used to analyze the characteristics of these three types of clinical data, then summarized the clinical phenotype composition ratio and clinical data characteristics. Results: The patients with coal worker's pneumoconiosis were initially divided into three types, including 73 cases (60.3%) in type 1, 18 cases (14.9%) in type 2 and 30 cases (24.8%) in type 3. Patients in type 1 are mainly middle-aged, with little damage to lung function and mild clinical symptoms, the imaging manifestations of type 1 patients are mainly diffuse nodules, and the stages of pneumoconiosis are mostly one-stage and second-stage. Patients in type 2 are mainly in middle-aged and elderly patients.the main pulmonary impairment is diffuse function decline. The clinical symptoms are severe and the imaging manifestations are complex. The stages of pneumoconiosis are one, second and third stages. Patients in type 3 are mainly middle-aged and elderly patients, with more pulmonary function impairment (decreased ventilation and diffusion) , severe clinical symptoms, complex imaging manifestations (micro nodules, emphysema, mass shadow, fibrosis) , and those pneumoconiosis stages are mainly in the second and third stages. Conclusion: According to the clinical characteristics, the patients with coal worker's pneumoconiosis were divided into 3 types by cluster analysis method, the treatment plan has certain guiding value in clinical work according to different classifications.

Abstract
PTPN11 (coding the gene of SHP2), a classic non-receptor protein tyrosine phosphatase, is implicated in multiple cell signaling pathway. Abnormal activation of SHP2 has been shown to contribute to a variety of human diseases, including Juvenile myelomonocytic leukemia (JMML), Noonan syndrome and tumors. Thus, the SHP2 inhibitors have important therapeutic value. Here, based on the compound PubChem CID 8,478,960 (IC50 = 45.01 μM), a series of thiophene [2,3-d] pyrimidine derivatives (IC50 = 0.4-37.87 μM) were discovered as novel and efficient inhibitors of SHP2 through powerful "core hopping" and CDOCKER technology. Furthermore, the SHP2-PTP phosphatase activity assay indicated that Comp#5 (IC50 = 0.4 μM) was the most active SHP2 inhibitor. Subsequently, the effects of Comp#5 on the structure and function of SHP2 were investigated through molecular dynamics (MD) simulation and post-kinetic analysis. The result indicated that Comp#5 enhanced the interaction of residues THR357, ARG362, LYS366, PRO424, CYS459, SER460, ALA461, ILE463, ARG465, THR507 and GLN510 with the surrounding residues, improving the stability of the catalytic active region and the entrance of catalytic active region. In particular, the Comp#5 conjugated with residue ARG362, elevating the efficient and selectivity of SHP2 protein. The study here may pave the way for discovering the novel SHP2 inhibitors for suffering cancer patients.

Abstract
When wars, major disasters, or epidemics of the infectious diseases occur, existing medical facilities are usually unable to implement timely and effective treatment for patients, or the reception capacity is difficult to meet the surge in demand for health care. The makeshift emergency hospitals are built for patient reception, treatment and even isolation for infectious disease control. The makeshift hospitals have developed and improved in modern times, including mobile field hospitals, field tent hospitals and navy hospital ships equipped with advanced equipment and commonly used for military purposes, or temporary hospitals built in large public buildings and newly built hospitals in support of disaster relief and humanitarian operation. Makeshift hospitals have played an important role in response to many disasters and epidemics globally. This paper briefly summarizes the history, types, and applications of makeshift hospitals in disasters and epidemic responses.

Abstract
Surface magnetism and its correlation with the electronic structure are critical to understanding the topological surface state in the intrinsic magnetic topological insulator MnBi_{2}Te_{4}. Here, using static and time resolved angle-resolved photoemission spectroscopy (ARPES), we find a significant ARPES intensity change together with a gap opening on a Rashba-like conduction band. Comparison with a model simulation strongly indicates that the surface magnetism on cleaved MnBi_{2}Te_{4} is the same as its bulk state. The inability of surface ferromagnetism to open a gap in the topological surface state uncovers the novel complexity of MnBi_{2}Te_{4} that may be responsible for the low quantum anomalous Hall temperature of exfoliated MnBi_{2}Te_{4}.

Abstract
Coronavirus disease 2019 (COVID-19) can cause great damage to the elderly patients and lead to high mortality. The clinical presentations and auxiliary examinations of the elderly patients with COVID-19 are atypical, due to the physiological ageing deterioration and basal pathological state. The treatment strategy for the elderly patients has its own characteristics and treatment protocol should be considered accordingly. To improve the diagnosis, treatment, and prevention of COVID-19 in the elderly, the Expert Committee of Geriatric Respiratory and Critical Care Medicine, China Society of Geriatrics established the "Expert consensus for the diagnosis, treatment, and prevention of Coronavirus disease 2019 in the elderly" . We focused on the clinical characteristics and key points for better treatment and prevention of COVID-19 in the elderly. (1) For diagnosis, atypical clinical presentation of COVID-19 in the elderly should be emphasized, which may be complicated by underlying disease. (2) For treatment, strategy of multiple disciplinary team (mainly the respiratory and critical care medicine) should be adopted and multiple systemic functions should be considered. (3) For prevention, health care model about integrated management of acute and chronic diseases, in and out of hospital should be applied.

Abstract
Objective: To study the clinicopathological characteristics, diagnosis and differential diagnosis of bronchiolar adenoma (BA). Methods: Fifteen cases of BA were collected from the First Affiliated Hospital of Nanjing Medical University, from January 2016 to October 2019. The clinical data, imaging examination, morphology, immunostaining and molecular changes were retrospectively analyzed. Results: There were 3 males, 12 females, most of the patients were female, mainly in middle-aged to elderly (51-77 years). Three had smoking history. The patients usually had no clinical symptoms. Imaging findings were ground-glass and/or lobulated nodules. Grossly, the tumors were gray-whitish, taupe solid or focally microcystic nodules with distinct boundary but no capsule. The maximum diameter was 0.4-2.5 cm (mean 1.0 cm). Histologically, there were glandular, papillary, or flat patterns that were composed of basal cells, mucous cells, ciliated cells and type Ⅱ pneumocytes, some of which showed basal cell proliferation and squamous cell metaplasia. However, there were some cases with few or even without mucous and/or ciliated cells. Immunostaining highlighted the continuous basal cell layer (positive for p63, p40 and cytokeratin 5/6), which was the most important diagnostic evidence. Genetic tests did not show mutation in BRAF or EGFR genes. All patients were followed up for 1-41 months, and they were without recurrence or metastasis. Conclusions: BA is a benign neoplasm that develops in the peripheral lung with good prognosis. Definite diagnosis is very crucial for surgical treatment, especially in frozen consultation. Immunohistochemistry will be helpful if necessary.

Abstract
Objectives: To summarize the clinical and genetic characteristics of the patients with isolated methylmalonic acidemia and investigate the strategies for the diagnosis, treatment and prevention. Methods: Three hundred and fourteen patients (180 males, 134 females) with isolated methylmalonic acidemia were ascertained from 26 provinces or cities across the mainland of China during January 1998 to March 2020. Genetic analysis was performed by Sanger sequencing, gene panel sequencing, whole exome sequencing, multiplex ligation-dependent probe amplification or quantitative PCR. According to the age of onset, the patients were divided to early-onset group (≤12 months of age) and the late-onset group (>12 months of age). They were treated by cobalamin, L-carnitine and (or) special diet and symptomatic treatment. Statistical analysis was done using Chi-square test. Results: Fifty-eight of 314 (18.5%) patients were detected by Newborn screening using liquid chromatography tandem mass spectrometry. Five cases (1.6%) had a postmortem diagnosis. Two hundred and fifty-one patients (79.9%) were clinically diagnosed with an age of onset ranged from 3 hours after birth to 18 years. One hundred and fifty-nine patients (71.0%) belonged to early-onset groups, 65 patients (29.0%) belonged to the late-onset group. The most common symptoms were metabolic crises, psychomotor retardation, epilepsy, anemia and multiple organ damage. Metabolic acidosis and anemia were more common in early-onset patients than that in late-onset patients (20.8%(33/159) vs. 9.2% (6/65), 34.6% (55/159) vs. 16.9% (11/165), χ(2)=4.261, 6.930, P=0.039, 0.008). Genetic tests were performed for 236 patients (75.2%), 96.2%(227/236) had molecular confirmation. One hundred and twenty-seven variants were identified in seven genes (MMUT, MMAA, MMAB, MMADHC, SUCLG1, SUCLA2, and MCEE), of which 49 were novel. The mut type, caused by the deficiency of methylmalonyl-CoA mutase, was the most common (n=211, 93%) cause of this condition. c.729_730insTT, c.1106G>A and c.914T>C were the three most frequent mutations in MMUT gene. The frequency of c.914T>C in early-onset patients was significantly higher than that in late-onset patients (8.3% (18/216) vs. 1.6% (1/64), χ(2)=3.859, P=0.037). Metabolic crisis was more frequent in mut type than the other types (72.6% (114/157) vs. 3/13, χ(2)=13.729, P=0.001),developmental delay and hypotonia were less frequent in mut type (38.2% (60/157) vs. 9/13, 25.5% (40/157) vs. 8/13, χ(2)=4.789, 7.705, P=0.030, 0.006). Of the 58 patients identified by newborn screening, 44 patients (75.9%) who were treated from asymptomatic phase developed normally whereas 14 patients (24.1%) who received treatment after developing symptoms exhibited varying degrees of psychomotor retardation. Conclusions: The characteristics of phenotypes and genotypes among Chinese patients with isolated methylmalonic acidemia were analyzed. Expanded the mutation spectrum of the associated genes. Because of the complex clinical manifestations and severe early onset of isolated methylmalonic acidemia, Newborn screening is crucial for early diagnosis and improvement of prognosis. MMUT gene is recommended for carrier screening as an effort to move the test earlier as a part of the primary prevention of birth defects.

Abstract
When wars, major disasters, or epidemics of the infectious diseases occur, existing medical facilities are usually unable to implement timely and effective treatment for patients, or the reception capacity is difficult to meet the surge in demand for health care. The makeshift emergency hospitals are built for patient reception, treatment, and even isolation for infectious disease control. The makeshift hospitals have developed and improved in modern times, including mobile field hospitals, field tent hospitals, and navy hospital ships equipped with advanced equipment and commonly used for military purposes or in support of disaster relief and humanitarian operation, and temporary hospitals built in large public buildings, and newly built hospitals. Makeshift hospitals have played an important role in response to many disasters and epidemics globally. This paper briefly summarizes the history, types, and applications of makeshift hospitals in disaster and epidemic response.

Abstract
Objective: To investigate the clinical effects of first generation epithelial growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) compared with platinum-based chemotherapy as first-line therapy in advanced lung adenocarcinoma patients with uncommon EGFR mutations. Methods: Clinical data of 4 276 patients diagnosed as advanced lung adenocarcinoma (ⅢB/Ⅳ) underwent EGFR gene detection at the Affiliated Cancer Hospital of Zhengzhou University from January 2012 to February 2018 were collected and 99 cases with uncommon EGFR mutations were selected. The clinical pathological features, treatment outcomes, treatment options and prognosis after first-line treatment of the 99 cases were analysed and compared with other patients with common EGFR mutations. Results: The objective response rates of patients with uncommon EGFR mutations receiving EGFR-TKIs or platinum-based chemotherapy were 33.0% and 27.1%, respectively. The disease control rates were 76.5% and 87.5%, respectively. The progression-free survival (PFS) of patients treated with EGFR-TKIs was 7.2 months, significantly superior than 4.9 months of patients receiving chemotherapy (P=0.009). The overall survival of patients treated with EGFR-TKIs was 14.3 months, significantly worse than 20.7 months of patients receiving chemotherapy (P=0.034). Multivariate analysis showed that distant metastases (P=0.001) and smoking history (P=0.013) were independent prognostic factors for OS of lung adenocarcinoma patients with EGFR uncommon mutations. Conclusions: Compared with chemotherapy, the usage of first generation of EGFR-TKIs as first-line therapy can improve the short-term efficacy of advanced lung adenocarcinoma patients with EGFR uncommon mutations. However, platinum-based chemotherapy shows a longer overall survival.

Abstract
Objective To evaluate the effect of 56 ancestry informative single nucleotide polymorphism (aiSNP) genetic markers in the ForenSeqTM DNA Signature Prep Kit on ancestry inference. Methods A total of 85 samples from five populations including Hebei Han population, Inner Mongolia autonomous region Mongolian population, Tibet autonomous region Tibetan population, Xinjiang Uygur autonomous region Uygur population and Nigerian population were collected. The library was constructed with the ForenSeqTM DNA Signature Prep Kit and sequencing was performed based on the MiSeq FGx Forensic Genomics System. Using universal analysis software (UAS) of ForenSeqTM, principal component analysis (PCA), Structure and likelihood ratio method was used on the genotyping data of 56 aiSNP markers, respectively, and the genetic relationships between populations and inference of the origin of ancestors were analyzed. Results Among the five populations tested, the four ethnic populations in China (Hebei Han population, Inner Mongolia autonomous region Mongolian population, Tibet autonomous region Tibetan population and Xinjiang Uygur autonomous region Uygur population) could be significantly distinguished from Nigerian population. Xinjiang Uygur autonomous region Uygur individuals were shown as having mixed origins of ancestors and could be distinguished from the other three Chinese populations. However, the other three populations in China (Hebei Han population, Inner Mongolia autonomous region Mongolian population and Tibet autonomous region Tibetan population) could not be effectively distinguished by the system. Conclusion The 56 aiSNP markers in the ForenSeqTM DNA Signature Prep Kit can make accurate ancestry inference from the intercontinental level, but it is not yet able to distinguish between Chinese subpopulations.

Abstract
OBJECTIVE To explore the hemodynamic changes in standing-up test of children and adolescents with postural tachycardia syndrome (POTS) and to compare hemodynamic parameters of POTS patients with decreased cardiac index (CI) and those with not-decreased CI. METHODS A retrospective study was conducted to show the trends of CI, total peripheral vascular resistance index (TPVRI), heart rate and blood pressure in standing-up test of 26 POTS patients and 12 healthy controls, and to compare them between the two groups. The POTS patients were divided into two groups based on CI decreasing or not in standing-up test, namely decreased CI group (14 cases) and not-decreased CI group (12 cases). The trends of the above mentioned hemodynamic parameters in standing-up test were observed and compared between decreased CI group and not-decreased CI group. RESULTS In standing-up test for all the POTS patients, CI (F=6.936, P=0.001) and systolic blood pressure (F=6.049, P<0.001) both decreased significantly, and heart rate increased obviously (F=113.926, P<0.001). However, TPVRI (F=2.031, P=0.138) and diastolic blood pressure (F=2.018, P=0.113) had no significant changes. For healthy controls, CI (F=3.646, P=0.016), heart rate (F=43.970, P<0.001), systolic blood pressure (F=4.043, P=0.020) and diastolic blood pressure (F=8.627, P<0.001) all increased significantly in standing-up test. TPVRI (F=1.688, P=0.190) did not change obviously. The changing trends of CI (F=6.221, P=0.001), heart rate (F=6.203, P<0.001) and systolic blood pressure (F=7.946, P<0.001) over time were significantly different between the patients and healthy controls, however, no difference was found in TPVRI and diastolic blood pressure (P > 0.05). Among the POTS patients, CI was significantly different between decreased CI group and not-decreased CI group (F=14.723, P<0.001). Systolic blood pressure of the former decreased obviously (F=8.010, P<0.001), but it did not change obviously in the latter (F=0.612, P=0.639). Furthermore, none of the changes of TPVRI, heart rate and diastolic blood pressure in standing-up test were significantly different between the two groups (P > 0.05). Age was an independent factor for decreased CI patients (P=0.013, OR=2.233; 95% CI, 1.183 to 4.216). CONCLUSION POTS patients experience vital hemodynamic changes in standing-up test, part of them suffering from decreased CI, but others from not-decreased CI. Age is an independent factor for patients suffering from decreased CI.

Abstract
Abstract Objective To evaluate the effectiveness of single nucleotide polymorphism (SNP) genoty-ping in combination with identity by state (IBS) strategy in full sibling testing. Methods Thirty-five blood samples were collected from a four-generation family. Ninety autosomal SNPs were genotyped using Precision ID Identity Panel. The distribution of IBS scores for full siblings and other relationships were calculated and compared. The relationships were determined using Fisher discriminant function and threshold method, respectively. Results Based on family members and previous research, 44, 30, 111, 71 and 1 000 pairs of full siblings (FS), grandparent-grandchild (GG), uncle/aunt-nephew/niece (UN), first cousins (FC) and unrelated individuals (UI) were obtained, respectively. The average IBS scores were 148, 130, 132, 124 and 120, respectively. Except for the GG and UN pairs, the distribution differences among the other relationships had statistical significance (P<0.05). The false rates of Fisher discriminant function to determine relationships were 1.3%, 22.3%, 17.0% and 38.7% for FS, GG, UN and FC, respectively. Based on the simulation data, the thresholds t1=128 and t2=141 were recommended to determine full sibling relationships (the false rate ≤0.05%). Conclusion The 90 SNP genetic markers included in the Precision ID Identity Panel meet the testing requirements for full sibling relationships. The threshold method based on IBS has a relatively lower false rate and is more flexible.

Abstract
Abstract Objective To compare the differences of cardiotoxicity of alcohol extract from root, stem and leaf of Chloranthus serratus in the rats, and discuss preliminarily its mechanism of toxicity. Methods Rats were randomly divided into four groups: blank, root alcohol, stem alcohol and leaf alcohol, with 8 in each group. After 14 days of continuous intragastric administration, the body mass change curves were drawn. The cardiac coefficient was calculated. The contents of creatine kinase (CK), creatine kinase isoenzyme (CK-MB), lactate dehydrogenase (LDH) and α-hydroxybutyrate dehydrogenase (α-HBDH) as well as the content changes of oxidative stress indexes - total superoxide dismutase (T-SOD) and malondialdehyde (MDA) in the serum of rats were detected. The cardiac pathomorphology changes in the rats were observed. The expression of intercellular adhesion molecule (ICAM-1) and heme oxygenase (HO-1) in myocardial tissue was detected. Results Body mass growth rate: stem alcohol group was the smallest, followed by leaf alcohol group. The difference of cardiac coefficient of every group had no statistical significance (P>0.05). The myocardial tissues of stem alcohol group suffered the most serious damage, followed by the leaf alcohol group. The contents of CK, CK-MB, LDH and α-HBDH in stem alcohol group increased (P<0.05). The increase of MDA content and decrease of T-SOD content in stem alcohol group had statistical significance compared with the blank group and root alcohol group, while the leaf alcohol group only had statistical significance in the decrease of T-SOD content compared with the blank group (P<0.05). The positive expression of ICAM-1 enhanced and the expression of HO-1 protein decreased in every group after the intervention of different extracts. The change trend was stem alcohol > leaf alcohol > root alcohol group. Conclusion The alcohol extract from the stem has the highest cardiotoxicity, followed by the leaf extract, and its mechanism of toxicity may be related to oxidative stress.

Abstract
Objective: To observe the incidence and severity of retinopathy of prematurity (ROP) in extremely low birth weight (ELBW) infants by strictly controlling the risk factors of ROP, such as oxygen inhalation after birth, to explore the related factors of ROP in ELBW infants. Methods: This was a cross-sectional study. 166 ELBW infants underwent neonatal screening were enrolled in this study, whose birth weight was less than 1 000 g. There were 79 males and 87 females infants, whose average gestational age was (27.99±1.73)weeks, and average birth weight was (904.45±80.23)g. According to the final screening results, the ELBW infants were grouped as follows: (1)ROP group and non-ROP group; (2)severe ROP group and mild or no ROP group. Risk factors included gestational age, birth weight, test-tube infants, fetuses number, complications during pregnancy, delivery mode and Apgar scores in 1 to 10 minutes, weight and weight gain proportion at 1-6 weeks after birth, postnatal feeding mode, history of oxygen inhalation, anemia and blood transfusion, and other systemic diseases were recorded. And their correlation with severe ROP was analyzed by SPSS 20.0 statistical software. Results: Ninty-four (56.63%) ELBW infants developed ROP, 16 (9.64%) were severe ROP and 14(8.43%) received treatment. Average birth weight between ROP group (911.95±72.80)g and non-ROP group (894.67±88.58)g had no difference(t=1.379, P=0.170). Average gestational age between ROP group (27.49±1.53) weeks and non-ROP group (28.64±1.76) weeks had significant difference(t=-4.491,P<0.001).And pregnancy-induced hypertension during pregnancy (χ(2)=4.479, P=0.034), Apgar score in 5 minutes (t=-2.760, P=0.006) and 10 minutes (t=-2.099, P=0.043), pneumonia (χ(2)=6.233, P=0.013), neonatal pneumonia (χ(2)=18.026, P<0.001) had significant difference between ROP group and non-ROP group. There was no effect on weight (F=0.009,P=0.753) or weight gain proportion (F=2.394,P=0.124) at 1-6 weeks after birth in ELBW infants with or without ROP. Average birth weight between severe ROP group(875.63±74.85)g and mild or no ROP group(907.53±80.41)g had no difference(t=-1.518, P=0.131).Average gestational age between severe ROP group(26.88±1.31)weeks and mild or no ROP group (28.11±1.73)weeks had significant difference(t=-2.766,P=0.006).And only fundus hemorrhage (χ(2)=4.507,P=0.034) had significant difference between severe ROP group and mild or no ROP group. There was no effect on weight (F=2.683,P=0.103) or weight gain proportion (F=0.431,P=0.513) at 1-6 weeks after birth in ELBW infants with or without ROP. Logistic regression analysis revealed that only gestational age was correlated to the incidence (β=-0.437,P<0.001) and severity (β=-0.616,P=0.007) of ROP significantly. Conclusion: By strictly controlling the risk factors of ROP, such as oxygen inhalation after birth, the severe rate of ROP in ELBW infants is low. However, gestational age is still the inevitable independent high risk factor for the incidence of ROP in ELBW infants. (Chin J Ophthalmol, 2019, 55:280-288).

Abstract
Objective: To establish comprehensive laboratory reference intervals for Chinese children. Methods: This was a cross-sectional multicenter study. From June 2013 to December 2014, eligible healthy children aged from 6-month to 17-year were enrolled from 20 medical centers with informed consent. They were assessed by physical examination, questionnaire survey and abdominal ultrasound for eligibility. Fasting blood samples were collected and delivered to central laboratory. Measurements of 15 clinical laboratory parameters were performed, including estradiol (E2), testosterone(T), luteinizing hormone(LH), follicle-stimulating hormone(FSH), alanine transaminase(ALT), serum creatinine(Scr), cystatin C, immunoglobulin A(IgA), immunoglobulin G(IgG), immunoglobulin M(IgM), complement (C3, C4), alkaline phosphatase(ALP), uric acid(UA) and creatine kinase(CK). Reference intervals were established according to central 95% confidence intervals for reference population, stratified by age and sex. Results: In total, 2 259 children were enrolled. Finally, 1 648 children were eligible for this study, including 830 boys and 818 girls, at a mean age of 7.4 years. Age- and sex- specific reference intervals have been established for the parameters. Reference intervals of sex hormones increased gradually with age. Concentrations of ALT, cystatin C, ALP and CK were higher in children under 2 years old. Serum levels of sex hormones, creatinine, immunoglobin, CK, ALP and urea increased rapidly in adolescence, with significant sex difference. In addition, reference intervals were variable depending on assay methods. Concentrations of ALT detected by reagents with pyridoxal 5'-phosphate(PLP) were higher than those detected by reagents without PLP. Compared with enzymatic method, Jaffe assay always got higher results of serum creatinine, especially in children younger than 9 years old. Conclusion: This study established age- and sex- specific reference intervals, for 15 clinical laboratory parameters based on defined healthy children.

Abstract
Objective: To describe the prevalence of preterm birth (PB), low birth weight (LBW), and small for gestational age (SGA) among HIV-infected pregnant women and to identify associated risk factors in Hunan province. Methods: This study appeared a retrospective one on HIV-infected pregnant women retrieved from Information System of Prevention of Mother-to-child Transmission of HIV management in Hunan province, between January 2011 and December 2017. Information regarding demographic characteristics, pregnancy, antiretroviral therapy (ART), husbands/partners' relevant situation and pregnancy outcomes, among these HIV-infected pregnant women were collected and analyzed. The incidence rates on PB, LBW and SGA were calculated. Multivariate logistic regression was used to analyze the associated risk factors. Results: A total of 780 HIV-infected pregnant women were enrolled. The prevalence rates on PB, LBW and SGA in HIV- infected pregnant women appeared as 7.9% (62/780), 9.9% (77/780) and 21.3% (166/780), respectively. Results from the multivariate logistic regression analysis showed that factors as pregnancy related diseases as moderate/severe anemia, hypertensive, initial time of ART <14 gestational weeks (compared to those women without ART during pregnancy) and husbands/partners' age >35 years old (compared to husbands/partners' age 26-30 years old) etc., were associated with an increased risk of PB with adjusted OR as 4.59 (95%CI: 1.51-13.95), 4.90 (95%CI: 1.56-15.46), 2.40 (95%CI: 1.26- 4.56) and 2.29 (95%CI: 1.21-4.36). For LBW, pregnancy moderate/severe anemia, pregnancy HBV infection and initial time of ART <14 gestational weeks were associated with an increased risk of LBW, with adjusted OR as 3.28 (95%CI: 1.13-9.54), 4.37 (95%CI: 1.42-13.44) and 2.68 (95%CI: 1.51-4.76), respectively. For SGA, pregnancy HBV infection and initial time of ART <14 gestational weeks were risk factors for SGA, with adjusted OR as 4.41 (95%CI: 1.43-13.63) and 2.67 (95%CI: 1.51-4.73), respectively. Conclusion: Preterm birth, LBW and SGA were common adverse pregnancy outcomes for HIV-infected pregnant women and were associated with factors as pregnancy complications, ART and husbands/partners' age.

Abstract
To explore the functional phenotype of liver macrophages in patients with autoimmune hepatitis (AIH). Compared with patients with nonalcoholic fatty liver disease (NAFLD) and chronic hepatitis B (CHB), the absolute CD(68)(+) cell count in patients with AIH was significantly higher (all P<0.05). It was positively correlated with ALT and IgG levels (the correlation coefficients 0.600 and 0.700, P=0.285 and 0.188 respectively). Additionally, compared with patients with NAFLD, the absolute iNOS positive cell count in patients with AIH and CHB were significantly higher (all P<0.05). The expression of TNFα, iNOS and IL-1β in patients with AIH and CHB were significantly higher than in patients with NAFLD (all P<0.05). Interestingly, compared with patients with AIH and CHB, the absolute CD(206)(+) cell count in patients with NAFLD were significantly higher (all P<0.05). CD(206) expression in patients with NAFLD was higher than patients with AIH and CHB, but with no statistical significance. M1 type macrophages over-expressed and played a major role in the inflammatory reaction and liver injury in patients with AIH.
