Objective To investigate the value of serum chitinase-3-like protein 1 (CHI3L1) in predicting the risk of decompensation events in patients with liver cirrhosis, since prediction of decompensation events and adoption of active preventive measures are the key to improving the survival time of patients with liver cirrhosis. Methods A case-control study was conducted for 305 patients with liver cirrhosis who were diagnosed and treated in Tianjin Second People's Hospital from January 2019 to May 2021, among whom there were 200 patients with compensated liver cirrhosis and 105 patients with decompensated liver cirrhosis at baseline. According to whether decompensation events occurred within 1 year, the 305 patients with liver cirrhosis were divided into decompensation group with 79 patients and non-decompensation group with 226 patients; according to whether decompensation events occurred for the first time within 1 year, the 200 patients with compensated liver cirrhosis were divided into first-time decompensation group with 43 patients and non-first-time decompensation group with 157 patients. The independent samples t -test or the Mann-Whitney U test was used for comparison of normally distributed continuous data between groups, and the Wilcoxon rank-sum test or the chi-square test was used for comparison of categorical data between groups. The binary logistic regression analysis was used to investigate the association between each variable and decompensation events; the receiver operating characteristic (ROC) curve and the area under the ROC curve (AUC) were used to investigate the value of each variable in predicting decompensation events, and the maximum value of Youden index was used to determine the optimal cut-off value. Results The patients who experienced decompensation events within 1 year had a significantly higher baseline serum level of CHI3L1 than those who did not experience such events [243.00 (136.00-372.00) ng/mL vs 117.50 (67.75-205.25) ng/mL, U =4720.500, P < 0.001], and the patients who experienced decompensation events for the first time within 1 year had a significantly higher baseline serum level of CHI3L1 than those who did not experience such events [227.98 (110.00-314.00) ng/mL vs 90.00 (58.00-168.50) ng/mL, U =1 681.500, P < 0.001]. Patients with cirrhosis with higher baseline CHI3L1 levels had an increased risk of decompensation events within 1 year ( OR =1.004, 95% CI : 1.002-1.006, P < 0.001); Patients with compensated cirrhosis with higher baseline serum CHI3L1 levels had an increased risk of first decompensated event within 1 year ( OR =1.006, 95% CI : 1.003-1.008, P < 0.001). The baseline serum level of CHI3L1 had an AUC of 0.751 in predicting the risk of first-time decompensation events, with a sensitivity of 90.7% and a specificity of 55.4% at the optimal cut-off value of 95.5 ng/mL. The predictive model based on the combination of serum CHI3L1 level and Child-Pugh class had an AUC of 0.809, with a sensitivity of 72.1% and a specificity of 77.1% at the maximum value of Youden index. Conclusion Serum CHI3L1 level can be used as an effective predictive factor for the risk of first-time decompensation events in patients with compensated liver cirrhosis, and its combination with Child-Pugh class shows a higher predictive value.

ObjectiveTo investigate the mechanism of Chaihu Shugansan in the treatment of functional dyspepsia in rats based on mitophagy and PTEN-induced kinase 1 （Pink1）/E3 ubiquitin ligase （Parkin）. signaling pathway. MethodAccording to the principle of random grouping， 40 SD rats were assigned into a normal group， a model group， a Chaihu Shugansan group， and a positive drug （domperidone） group， with 10 rats in each group. The rats in other groups except the normal group received tail-clamping stimulation to replicate the model of functional dyspepsia. After each time of stimulation， the rats in the normal， model， Chaihu Shugansan， and positive drug groups were administrated with normal saline， normal saline， Chaihu Shugansan （4.8 g·kg^-1）， and an aqueous solution of domperidone （4.5 mg·kg^-1）， respectively. After 28 days of modeling， the gastric emptying rate and the small intestine propulsion rate of the rats in each group were measured and the tissue samples were collected. Hematoxylin-eosin （HE） staining was employed for observation of damage in gastric antrum tissue， and transmission electron microscopy （TEM） for ultrastructural observation of gastric interstitial cells of Cajal （ICCs）. Immunofluorescence co-localization was adopted to observe the expression of cytochrome c oxidase （COX Ⅳ） and Parkin. Western blot was employed to determine the expression levels of microtubule-associated protein 1， light chain 3 （LC3）， and the mitophagy-associated proteins prohibitin2 （PHB2）， Pink1， Parkin， and ubiquitin-specific protease 30 （USP30）. ResultCompared with the normal group， the modeling decreased the gastric emptying rate and the small intestine propulsion rate （P<0.05）. Compared with the model group， Chaihu Shugansan increased the gastric emptying rate and the small intestine propulsion rate （P<0.05）. The results of TEM showed that Chaihu Shugansan reduced the swelling degree of mitochondria in gastric antrum tissue. Compared with the normal group， the modeling increased the fluorescence intensity of Parkin in mitochondria （P<0.01）， while such increase can be alleviated by Chaihu Shugansan （P<0.01）. Western blotting results showed that compared with the normal group， the modeling up-regulated the protein levels of LC3， Pink1， Parkin， and PHB2 （P<0.05， P<0.01） and down-regulated the protein level of USP30 （P<0.01）. Compared with the model group， Chaihu Shugansan down-regulated the protein levels of LC3， Pink1， Parkin， and PHB2 （P<0.05， P<0.01） and up-regulated the protein level of USP30 （P<0.01）. ConclusionChaihu Shugansan may treat functional dyspepsia by blocking the Pink1/Parkin signaling pathway to inhibit excessive mitochondrial autophagy in ICCs.

Objective:To investigate the efficacy of an additional augmentative locking compression plate combined with bone graft for aseptic subtrochanteric fracture nonunion after intramedullary nailing.Methods:From October 2016 to October 2019, 32 patients (25 males and 7 females) were treated at Department of Orthopedics, The Sixth People's Hospital Affiliated to Shanghai Jiaotong University for aseptic subtrochanteric fracture nonunion after intramedullary nailing. Their ages ranged from 27 to 68 years (average, 50.5 years) and their nonunion time from 9 to 24 months (average, 12.2 months). According to the Weber-Cech classification for nonunions, 9 cases belonged to the highly vascular type and 23 to the ischemic type. With the original intramedullary nails retained, all patients were fixated with an additional augmentative locking compression plate before simultaneous autologous iliac bone grafting. All patients were followed up regularly for fracture union, function of the affected hip and complications.Results:The 32 patients were followed up for 6 to 24 months (average, 12.9 months). All nonunions obtained clinical and imaging union. The clinical union time ranged from 3 to 8 months (average, 5.2 months), and the imaging union time from 6 to 10 months (average, 7.4 months). At the last follow-up, the therapeutic efficacy was evaluated as excellent in 28 cases and as good in 4, giving a good to excellent rate of 100%(32/32), according to the Sanders scoring for post-traumatic hip joint; the efficacy was evaluated as excellent in 21 cases, as good in 10 cases and as fair in one, giving a good to excellent rate of 96.9%(31/32), according to the Harris hip scoring. No such complications occurred as infection or loosening or breakage of internal fixation.Conclusion:An additional augmentative locking compression plate combined with bone graft is a reliable and effective treatment for aseptic subtrochanteric fracture nonunion after intramedullary nailing.

Xin'an doctor discussed acupuncture and moxibustion on ' and , calling it "orthodox needling method". 's academic thoughts on moxibustion were mainly reflected in () and (). made an incisive exposition of moxibustion treatment of heat syndrome, ulcer and other issues, and there is a corresponding test case for mutual reference. He believed that the moxibustion method only adapts to sick patients and holds opposition to moth moxibustion care for those who were disease-free; he also advocated that detailed verification of different syndrome should be conducted before acupuncture. This paper expounds 's academic thoughts on moxibustion can be used for heat syndrome, moxibustion does not stay phlegm, moxibustion need syndrome and moxibustion treatment of ulcer. It is believed that can present his own unique insights on the basis of his successors. He had played a guiding and promoting role in the development of academic theory of moxibustion.

To analyze statistically the situation of the National Natural Science Foundation of China (NSFC) from 2007 to 2016 in the field of acupuncture and moxibustion for supporting the national Universities colleges of traditional Chinese medicine on the General Program (GP) and the National Science Fund for Young Scholars (NSFYS). In view of five aspects, named fund, supporting units, key words, method, disorder and signal path, the differences were compared between GP and NSFYS, the following characteristics were summarized. ① The fund aid was increased from 2007 through 2013 and down-regulated from 2013 through 2016. In recent ten years, the funding condition was fluctuated, but increasing in tendency generally. ② The relevant projects of the same research direction had been approved continuously for over 3 years in a part of TCM universities, in which, the research continuity was the hot topic. ③ Regarding the therapeutic methods, acupuncture was the chief therapy; electroacupuncture, moxibustion and acupoints were involved as well. ④ The disorders involved in the research were cerebral ischemia, myocardial ischemia and reperfusion injury. It is suggested that the ischemic disorder is predominated in the research. ⑤ The signal path occupied the main research index system, including cell proliferation, metabolism, immune, apoptosis and autophagy.

Objective: To investigate the prevalence of dyslipidemia among adults in the southern mountains of Ningxia Hui Aulonomous Region. Methods: A cross-sectional study was conducted among a representative sample of 10 639 adults in the southern mountains using a population proportionate-sampling method in 2014. Questionnaires were completed and physical and laboratory examinations were performed. A total of 10 172 subjects were included in the analysis after excluding those with missing data. Dyslipidemia was diagnosed according to "Chinese guidelines for the prevention and treatment of dyslipidemia in adults" (2007). Results: The prevalence of dyslipidemia, hypercholesterolemia, hypertriglyceridemia, decreased high-density lipoprotein cholesterol (HDL-C), and increased low-density lipoprotein cholesterol (LDL-C) was 33.90%, 0.30%, 12.52%, 28.53%, and 1.14%, and the age-specific prevalence was 32.42%, 0.29%, 10.97%, 27.70%, and 1.07%, respectively. Borderline high triglycerides and borderline increased LDL-C were found in 13.09% and 6.52% of the study population, respectively. The rates of hypertriglyceridemia, decreased HDL-C, and dyslipidemia were higher in males than in females (P<0.05). The prevalence of dyslipidemia was higher in the group characterized by the risk factors of obesity, hypertension, diabetes, hyperuricemia, smoking, and drinking, compared to those without these factors (P<0.05). Conclusion The prevalence of dyslipidemia was higher in men than in women, and the differences were statistically significant. Hypertriglyceridemia and decreased HDL-C were the two major types of dyslipidemia. Obesity, hypertension, diabetes, hyperuricemia, smoking, and drinking alcohol increased the risk of dyslipidemia.

Objective: To prepare peptide minotope-based recombinant diagnostic antigen of Epstein-Barr virus (EBV) infection and evaluate its antigenicity preliminarily. Methods: With Trx at the N-terminal and His tag at the C-terminal, the peptide minotope of EBV (GP125, F1, A2, A3C2) was expressed in Escherichia coli and purified by affinity and anion exchange chromatography (designated 'H58’); based on antigenicity of H58 identified by Western blotting (WB), we constructed and evaluated a novel early diagnostic ELISA for EBV infection. Results: The soluble H58 protein with high concentration (2.8 mg/ml) and purity (99.01) was obtained; WB analysis found that there was an obvious band (28 ×10³) on the NC membrane, using H58 anti-Trx monoclonal antibody or acute-phase sera of EBV infection as the first antibody. With the novel ELISA, 50 positive sera of EBV infection and 50 negative sera were detected, displaying that the grouping of OD value of positive serum (95%CI: 1.233-1.489) and negative serum (95%CI: 0.113-0.159) was different (P<0.05) with the sensitivity 98.0%, specificity 96.0% and kappa value 0.940. Conclusions By E. coli expression and affinity and ion exchange chromatography purification, the peptide minotope-based recombinant diagnostic antigen of EBV infection was obtained with excellent antigenicity, which could be applied for serological detection of EBV infection.

Objective To investigate the prevalences of the obesity and hypertension in southern mountain regions of Ningxia. Methods A cross-sectional study was conducted among a representative sample of 10 639 adults using questionnaires, physical examinations, and blood pressure measurement in southern mountain areas with a population proportionate sampling method. Results The prevalences of overweight,obesity,central obesity,high percentage of body fat,and hypertension were 33.53%,10.71%,19.50%,27.69%,and 31.57% respectively, which were 30.31%,9.62%,16.70%,24.90%,and 27.61% after age-adjustment in rural areas of Ningxia,and increased with aging(Ptrend<0.05). The prevalences of overweight,obesity,and hypertension were higher in males than those in females(P<0.05),and that of central obesity was higher in females than in males(P=0.003).The prevalences of hypertension in subjects with overweight, obesity, central obesity, high percentage of body fat were 38. 14%, 53.75%,52.69%,and 48.90%,respectively. Body mass index,waist circumference,and percentage of body fat were positively correlated with systolic and diastolic blood pressure(P<0.05). The multivariable logistic model revealed that the risk of hypertension in different types of obesity increased about 1.5 times. Conclusion There is high prevalence of obesity and hypertension among the adults in southern mountain areas of Ningxia. The prevalence of hypertension in obesity,central obesity,and high percentage of body fat is closed to or more than half of the population investigated.

Objective To investigate the prevalence and risk factors of diabetes and prediabetes in Jingyuan County in Ningxia. Methods A cross-sectional survey including 10 639 participants (18-88 years of age) with a multistage sampling was conducted in Jingyuan County between January, 2014 and April, 2015. Questionnaires, physical examinations, and laboratory tests were included in the survey. Results Among all the subjects, 10 491 participants (men: 4 826, women: 5 665) with complete data were included in the analysis. The standardized prevalence of diabetes and prediabetes was 4.2% (men: 3.9%, women: 4.5%) and 8.8% (men: 7.6%, women 10.3%), respectively, in which the standardized prevalence of diabetes was higher in Hui (4.5%) than that in Han (3.5%) (P<0.05). Logistic regression analyses showed that age, family history of diabetes, overweight/obesity, hypertriglyceridemia and hypertension were positively associated with prediabetes and diabetes with the odds ratios being 1.60 and 2.14 (age, P<0.001), 1.40 and 3.32 (family history, P< 0.05), 1.47 and 1.57 (overweight/obesity, P< 0.001), 1.88 and 2.55 (hypertriglyceridemia, P<0.001), 1.44 and 1.89 (hypertension, P<0.001), respectively. Conclusions The prevalence of diabetes was relatively low in the rural area in Ningxia. However, it is still essential to take active interventions in people at high risk of diabetes in order to prevent the incident diabetes.
