ObjectiveTo explore the syndrome elements and evolving patterns of patients with hepatitis B virus-related acute on chronic liver failure （HBV-ACLF） at different stages. MethodsClinical information of 1,058 hospitalized HBV-ACLF patients， including 618 in the early stage， 355 in the middle stage， and 85 in the late stage， were collected from 18 clinical centers across 12 regions nationwide from January 1， 2012 to February 28， 2015. The “Hepatitis B-related Chronic and Acute Liver Failure Chinese Medicine Clinical Questionnaire” were designed to investigate the basic information of the patients， like the four diagnostic information （including symptoms， tongue， pulse） of traditional Chinese medicine （TCM）， and to count the frequency of the appearance of the four diagnostic information. Factor analysis and cluster analysis were employed to determine and statistically analyze the syndrome elements and patterns of HBV-ACLF patients at different stages. ResultsThere were 76 four diagnostic information from 1058 HBV-ACLF patients， and 53 four diagnostic information with a frequency of occurrence ≥ 5% were used as factor analysis entries， including 36 symptom information， 12 tongue information， and 5 pulse information. Four types of TCM patterns were identified in HBV-ACLF， which were liver-gallbladder damp-heat pattern， qi deficiency and blood stasis pattern， liver-kidney yin deficiency pattern， and spleen-kidney yang-deficiency pattern. In the early stage， heat （39.4%， 359/912） and dampness （27.5%， 251/912） were most common， and the pattern of the disease was dominated by liver-gallbladder damp-heat pattern （74.6%， 461/618）； in the middle stage， dampness （30.2%， 187/619） and blood stasis （20.7%， 128/619） were most common， and the patterns of the disease were dominated by liver-gallbladder damp-heat pattern （53.2%， 189/355）， and qi deficiency and blood stasis pattern （27.6%， 98/355）； and in the late stage， the pattern of the disease was dominated by qi deficiency （26.3%， 40/152） and yin deficiency （20.4%， 31/152）， and the patterns were dominated by qi deficiency and blood stasis pattern （36.5%， 31/85）， and liver-gallbladder damp-heat pattern （25.9%， 22/85）. ConclusionThere are significant differences in the distribution of syndrome elements and patterns at different stages of HBV-ACLF， presenting an overall trend of evolving patterns as "from excess to deficiency， transforming from excess to deficiency"， which is damp-heat → blood stasis → qi-blood yin-yang deficiency.

Objective To explore clinical outcomes and bone resection of interlaminar fenestration decompression and u-nilateral biportal endoscopic(UBE)technique in treating lumbar disc herniation(LDH).Methods A retrospective study was performed on 105 patients with single-level LDH treated from December 2019 to December 2021.Fifty-four patients in UBE group,including 32 males and 22 females,aged from 18 to 50 years old with an average of(38.7±9.3)years old,were treated with UBE,29 patients withL4.5and 25 patients with L5S1.There were 51 patients in small fenestration group,including 27 males and 24 females,aged from 18 to 50 years old with an average of(39.9±10.0)years old,were treated with small fenestra-tion,25 patients with L4.5 and 26 patients with L5S1.Perioperative indexes,such as operation time,postoperative time of getting out of bed and hospital stay were observed and compared between two groups.Visual analogue scale(VAS)and Oswestry dis-ability index(ODI)were compared between two groups before operation and 1,3,6 and 12 months after operation,respective-ly;and modified MacNab evaluation criteria was used to evaluate clinical efficacy.Amount of bone resection and retention rate of inferior articular process laminoid complex were compared between two groups.Results All 105 patients were successfully completed operation.Both of two groups were followed up from 6 to 12 months with an average of(10.69±2.49)months.Oper-ation time,postoperative time of getting out of bed and hospital stay were(58.20±5.54)min,(2.40±0.57)dand(3.80±0.61)d in UBE group,and(62.90±7.14)min,(4.40±0.64)d and(4.40±0.64)d in small fenestrum group,respectively;and had sta-tistically difference between two groups(P＜0.05).Postoperative VAS of low back and leg pain and ODI in both groups were significantly lower than those before surgery(P＜0.05).VAS of lumbar pain in UBE group(1.37±0.49)score was lower than that of small fenestration group(2.45±0.64)score,and had statistically difference(t=9.745,P＜0.05).Postoperative ODI in UBE group at 1 and 3 months were(28.54±3.31)％and(22.87±3.23)％,respectively,which were lower than those in small fenestra group(36.31±9.08)％and(29.90±8.36)％,and the difference was statistically significant(P＜0.05).There were no significant difference in VAS and ODI between two groups at other time points(P＞0.05).According to the modified MacNab evaluation criteria at the latest follow-up,49 patients got excellent result,3 good,and 2 fair in UBE group.In small fenestration group,35 patients got excellent,12 good,and 4 fair.In UBE group,amount of bone resection on L4,5 segment was(0.45±0.08)cm3 and(0.31±0.08)cm3 on the segment of L5S1.In small fenestration group,amount of bone resection on L4.5 segment was(0.57±0.07)cm3 and(0.49±0.04)cm3 on the segment of L5S1,and amount of bone resection of lower articular process laminar complex on the same segment in UBE group was less than that in small fenestration group(P＜0.05).In UBE group,retention rate of laminoid complex on L4,5 segment was(0.73±0.04)and L5S1 segment was(0.83±0.03),whileL4,5segment was(0.68± 0.06)and L5S1 segment was(0.74±0.04)in small fenestration group,the lower articular process laminar complex retention rate in UBE group was higher than that in small fenestration group(P＜0.05).Conclusion Both unilateral double-channel endoscopy and small fenestration of laminae could achieve good clinical results in treating LDH,but UBE has advantages of less trauma,higher eficiency,faster postoperative recovery and less damage to bone structure.

Mongolian medicine external treatment,which called five kinds of treatment in ancient time,is a kind of exter-nal treatment including fire moxibustion,poultice,soaking and other therapies.The therapy was gradually developed and per-fected in the course of Mongolian people's long-term struggle against diseases,which has characteristics of small trauma and suitable for long-term application.In this paper,the research progress of external treatment of orthopedic diseases in Mongolian medicine in recent years was summarized,and it was concluded that external treatment of orthopedic diseases in Mongolian medicine had distinct characteristics and accurate efficacy.However,there are still deficiencies in the standardization of clini-cal operation and the study of the mechanism of therapeutic action,which need further research and improvement.

Objective:To evaluate the efficacy and safety of vedolizumab (VDZ) in the treatment of active ulcerative colitis (UC).Methods:From November 1, 2020 to October 30, 2022, at the Department of Gastroenterology, the Sixth Affiliated Hospital of Sun Yat-sen University, 81 UC patients who received VDZ treatment and completed a 14-week follow-up were retrospectively selected. The clinical data of patients, including age, disease duration, disease activity of UC were collected. The VDZ efficacy evaluation included primary and secondary efficacy indicators. The primary efficacy indicator was the clinical remission rate after 14 weeks of VDZ treatment, and the secondary efficacy indicators included the clinical response rate, steroids-free remission rate, endoscopic remission rate after 14 weeks of treatment as well as the clinical response rate, clinical remission rate, steroids-free remission rate, secondary loss of response rate after 52 weeks of treatment. The adverse reactions during the treatment were recored. Taking clinical remission after 14 weeks of treatment as the dependent variable, univariate analysis was performed to identify the risk factors affecting clinical remission of VDZ. Binary logistic regression analysis was used for multivariate analysis to determine the independent risk factors of VDZ-included clinical remission. Chi-square test and Wilcoxon signed-rank test were used for statistical analysis.Results:Among the 81 UC patients, the age was 40.0 years old (29.0 years old, 53.5 years old) and the disease duration was 42.5 months (22.5 months, 94.7 months). The proportion of patients with mild active UC was 21.0% (17/81), the proportion of patients with moderate active UC was 64.2% (52/81), and the proportion of patients with severe active UC was 14.8% (12/81). After 14 weeks of treatment, the total Mayo score decreased from baseline level of 7.0 (6.0, 9.0) to 1.0 (0.0, 3.0), and the difference was statistically significant ( Z=-6.87, P<0.001). The clinical response rate was 84.0% (68/81) and the clinical remission rate was 69.1% (56/81) after 14 weeks of treatment. Of the 17 patients treated with combination of corticosteroid therapy, 10 achieved steroid-free remission, and the endoscopic remission rate was 34.8% (23/66). Of the 43 patients followed up to 52 weeks, the total Mayo score of UC patients decreased from baseline level of 7.0 (6.0, 9.0) to 0.0 (0.0, 1.0) after 52 weeks of treatment, and the difference was statistically significant ( Z=-3.25, P<0.001). The clinical response rate was 69.8% (30/43), and the clinical remission rate was 65.1% (28/43). Of the 13 patients treated with combination of corticosteroid therapy, 10 patients achieved steroid-free remission. The secondary loss of response rate was 15.2%(5/33) .The result of the univariate analysis showed that previous use of glucocorticoids was a risk factor of clinical remission after 14 weeks of VDZ treatment ( χ2=5.88, P=0.015). The result of multivariate logistic regression analysis showed that previous use of glucocorticoids was an independent risk factor of clinical remission after 14 weeks of VDZ treatment ( OR=3.429, 95% confidence interval 1.235 to 9.517, P=0.014). During the follow-up period, 12.3% (10/81) of patients developed Clostridium difficile infections, except for 1 case stopped VDZ treatment because the clinical response was not reached, remaining 9 cases continued VDZ treatment after received anti- Clostridium difficile treatment. Conclusion:VDZ has good clinical efficacy and safety in the treatment of Chinese UC patients, and patients with no history of glucocorticoid use may be more likely to achieve clinical remission after 14 weeks of treatment.

PURPOSE: High explosives are used to produce blast waves to study their biological effects. The lungs are considered as the critical target organ in blast-effect studies. The degree of lung hemorrhaging is related to both the explosive power and the increased lung weight. We studied the characteristics of the biological effects from an air explosion of a thermobaric bomb in a high-altitude environment and the lethality and lung injury severity of goats in different orientations and distances. METHODS: Goats were placed at 2.5, 3, 4, and 5 m from the explosion center and exposed them to an air blast at an altitude of 4700-meter. A group of them standing oriented to the right side and the other group seated facing the explosion center vertically. The lung injuries were quantified according to the percentage of surface area contused, and using the pathologic severity scale of lung blast injury (PSSLBI) to score the 4 injury categories (slight, moderate, serious and severe) as 1, 2, 3, and 4, respectively. The lung coefficient (lung weight [g]/body weight [kg]) was the indicator of pulmonary edema and was related to lung injury severity. Blast overpressure data were collected using blast test devices placed at matching locations to represent loadings to goats. All statistical analyses were performed using SPSS, version 26.0, statistical software (SPSS, Inc., Chicago, IL, USA). RESULTS: In total, 127 goats were involved in this study. Right-side-standing goats had a significantly higher mortality rate than those seated vertical-facing (p < 0.05). At the 2.5 m distance, the goat mortality was nearly 100%, whereas at 5 m, all the goats survived. Lung injuries of the right-side-standing goats were 1 - 2 grades more serious than those of seated goats at the same distances, the scores of PSSLBI were significantly higher than the seated vertical-facing goats (p < 0.05). The lung coefficient of the right-side-standing goats were significantly higher than those of seated vertical-facing (p < 0.05). Mortality, PSSLBI, and the lung coefficient results indicated that the right-side-standing goats experienced severer injuries than the seated vertical-facing goats, and the injuries were lessened as the distance increased. The blast overpressure was consistent with these results. CONCLUSION The main killing factors of the thermobaric bomb in the high-altitude environment were blast overpressure, blast wind propulsions and burn. The orientation and distances of the goats significantly affected the blast injury severity. These results may provide a research basis for diagnosing, treating and protecting against injuries from thermobaric explosions.

Objective:To assess the efficacy and safety of the combination therapy of camrelizumab, apatinib, nab-paclitaxel, and S-1 for patients with locally unresectable advanced gastric cancer.Methods:From September 1, 2019 to August 1, 2021, in Beijing Friendship Hospital Affiliated to Capital Medical University, 17 patients with advanced gastric cancer were enrolled in this prospective, single-arm study. All the enrolled patients received camrelizumab, nab-paclitaxel, apatinib and S-1 combination therapy (in each 21 days cycle, camrelizumab 200 mg intravenously, D1; nab-paclitaxel 240 mg/m 2 intravenously, D2; apatinib 500 mg orally, once a day, D1-D21; S-1 40-60 mg twice a day, D1-D14). Patients who have been evaluated by multidisciplinary team to be eligible for radical surgery should stop treatment for at least 2 weeks. Patients were discontinued from the study when disease progression or unbearable toxicity, or withdrew consent. We analyzed the conversion rate, objective response rate (ORR), disease control rate (DCR), overall survival (OS) and safety.Statistical data were show by numbers and persentages(%), and comparisons between subgroups were assessed by Fisher′s exact probability method. Patients survival was analyzed using Kaplan-Meier curves and compared between groups using Log-rank. Results:At the data of cutoff (December 15, 2021), the median follow-up duration was 19.6 months. Eight of 17 patients underwent gastrectomy, and all of them were R0 resection (47.1%, 95% CI: 0.262-0.690). ORR was 47.1%, DCR was 82.4%, the median overall survival was 23.63 months. Grade 3 and 4 adverse events occurred in 3 patients (17.6%), including neutropenia, thrombocytopenia, anemia and upper gastrointestinal hemorrhage. There were no serious treatment-related adverse events or treatment-related deaths. Conclusion:In this trial, the combination of camrelizumab, apatinib, nab-paclitaxel and S-1 as the conversion therapy showed significant anti-tumor activity and manageable adverse events, providing a new option for locally unresectable advanced gastric cancer.

OBJECTIVES: To study the value of heparin-binding protein (HBP) in the diagnosis of severe infection in children. METHODS: This study was a prospective observational study. The medical data of children who were admitted to the pediatric intensive care unit due to infection from January 2019 to January 2020 were collected. According to the diagnostic criteria for severe sepsis and sepsis, the children were divided into a severe sepsis group with 49 children, a sepsis group with 82 children, and a non-severe infection group with 33 children. The three groups were compared in terms of related biomarkers such as plasma HBP, serum C-reactive protein, serum procalcitonin, and platelet count. The receiver operating characteristic (ROC) curve was plotted to investigate the value of plasma HBP level in the diagnosis of severe infection (including severe sepsis and sepsis). RESULTS: The severe sepsis and sepsis groups had a significantly higher plasma HBP level on admission than the non-severe infection group (P<0.05). Compared with the sepsis and non-severe groups, the severe sepsis group had significantly higher serum levels of C-reactive protein and procalcitonin and a significantly lower platelet count (P<0.05). Plasma HBP level had an area under the ROC curve of 0.590 in determining severe infection, with a sensitivity of 38.0% and a specificity of 82.4% (P<0.05). CONCLUSIONS There is an increase in plasma HBP level in children with severe infection, and plasma HBP level has a lower sensitivity but a higher specificity in the diagnosis of severe infection and can thus be used as one of the markers for the judgment of severe infection in children.

To evaluate the data obtained from the external quality assurance program initiated by Chinese Rheumatism Data Center (CRDC-QAP) for autoantibodies detection in 2021, so as to assess the consensus and differences in cross-laboratory testing to autoantibodies in China. This is a retrospective study. After collecting data from the first half year (from May 15th to July 10th) and the second half year (from August 15th to November 19th) of CRDC-QAP program for autoantibody detection in 2021, it firstly analyzed the qualitative consensus of the cross-laboratory results. Secondly, it compared the positivity grade of numeric results according to the Sample to cut-off ratio (S/CO ratio) calculation. Finally, the mean and coefficient variation (CV) of numeric results from three major manufacturers were calculated. A total of 303 and 332 clinical labs voluntarily participated in the first half year and the second half year of CRDC-QAP program for autoantibody detection in 2021, respectively. Except for anti-β2 glycoprotein type I (aβ2-GPI) IgM, the cross-laboratory consensus of qualitative results for the other autoantibodies is greater than 96%. As for anti-cyclic citrullinated peptide antibody (anti-CCP) and anti mitochondrial antibody-M2 (AMA-M2), the numeric results from more than 90% laboratories showed the same positivity grade. More than 50% of laboratories used chemiluminescence immunoassay (CLIA) for quantitative evaluation of autoantibody. The CV of numeric results from different manufacturers showed certain differences(P<0.01) with the range from 0 to 238%. Although high consensus can be observed in term of qualitative result for autoantibody detection in cross-laboratory, there are still certain differences in numeric results in term of positivity grade and manufacturer-based CV.

Objective: The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population. Methods: The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models. Results: A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices). Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

Since 2015 when the transmission of schistosomiasis was controlled in China, the country has been moving towards elimination of schistosomiasis, with the surveillance-response as the main interventions for schistosomiasis control. During the period of the 13th Five-Year Plan, the transmission of schistosomiasis had been interrupted in four provinces of Sichuan, Jiangsu, Yunnan and Hubei and the prevalence of schistosomiasis has been at the historically lowest level in China. As a consequence, the goal set in The 13th Five-Year National Schistosomiasis Control Program in China is almost achieved. However, there are multiple challenges during the stage moving towards elimination of schistosomiasis in China, including the widespread distribution of intermediate host snails and complicated snail habitats, many types of sources of Schistosoma japonicum infections and difficulty in management of bovines and sheep, unmet requirements for the current schistosomiasis control program with the currently available tools, and vulnerable control achievements. During the 14th Five-Year period, it is crucial to consolidate the schistosomiasis control achievements and gradually solve the above difficulties, and critical to provide the basis for achieving the ultimate goal of elimination of schistosomiasis in China. Based on the past experiences from the national schistosomiasis control program and the challenges for schistosomiasis elimination in China, an expert consensus has been reached pertaining to the objectives, control strategy and measures for The 14th Five-Year National Schistosomiasis Control Program in China, so as to provide insights in to the development of The 14th Five-Year National Schistosomiasis Control Program in China.
