OBJECTIVE: To observe the efficacy of "Biaoben acupoint compatibility" moxibustion for abdominal obesity and its effect on blood lipid, lipid accumulation product (LAP) and cardiometabolic index (CMI). METHODS: A total of 150 patients with abdominal obesity were randomly divided into an observation group (75 cases, 5 cases dropped out) and a control group (75 cases, 6 cases dropped out). The control group received lifestyle guidance. The observation group received "Biaoben acupoint compatibility" moxibustion at Zhongwan (CV12), Guanyuan (CV4) and bilateral Tianshu (ST25), Zusanli (ST36) on the basis of the control group, 20 min each time, once every other day, 3 times a week for 8 weeks. Before and after treatment, the waist circumference, hip circumference, weight, body mass index (BMI) were observed, the levels of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C) were measured, and the LAP and CMI were calculated in the two groups. RESULTS: After treatment, the waist circumference, weight and BMI were decreased compared with those before treatment in both groups (P<0.05), the changes of the above indexes in the observation group were larger than those in the control group (P<0.05). After treatment, the hip circumference, TC level, TG level, LAP and CMI in the observation group were decreased compared with those before treatment (P<0.05), the HDL-C level was increased compared with that before treatment (P<0.05)；the changes of the TC level, TG level, LAP, CMI and HDL-C level in the observation group were larger than those in the control group (P<0.05). CONCLUSION "Biaoben acupoint compatibility" moxibustion can reduce the degree of obesity in patients with abdominal obesity, and improve blood lipid and reduce lipid accumulation.

OBJECTIVE: To observe the efficacy and safety of moxibustion in treating patients with central obesity of phlegm-dampness constitution. METHODS: A total of 66 patients with central obesity of phlegm-dampness constitution were randomly assigned to a moxibustion group (n=33, 3 cases dropped out) and a sham moxibustion group (n=33, 4 cases dropped out). The moxibustion group received mild moxibustion combined with lifestyle intervention; the moxibustion was applied at Shenque (CV8) and bilateral Zusanli (ST36), 30 min per session, maintaining a local skin temperature of (43±1) ℃. The sham moxibustion group received simulated moxibustion combined with lifestyle intervention; the simulated moxibustion was applied at the same acupoints, with the same session length, but with a maintained skin temperature of (37±1) ℃. Both groups were treated once every other day, three times per week for 8 consecutive weeks. Obesity-related physical indicators (waist circumference, hip circumference, body weight, body fat percentage, body mass index [BMI]), constitution evaluation indicators (phlegm-dampness constitution conversion score, symptom score), the impact of weight on quality of life-lite (IWQOL-Lite), the hospital anxiety and depression scale (HADS), and the incidence of adverse events were measured before and after treatment, and after 4 weeks of follow-up. RESULTS: Compared with before treatment, both groups showed significant reductions in waist circumference, hip circumference, body weight, body fat percentage, BMI, phlegm-dampness constitution conversion score and symptom score, IWQOL-Lite, and both anxiety and depression subscale scores of HADS after treatment and at follow-up (P<0.001). These improvements were significantly greater in the moxibustion group than those in the sham moxibustion group (P<0.001, P<0.01, P<0.05). One patient in the moxibustion group experienced a mild burn that resolved with routine care; the incidence of adverse reactions was 3.0% (1/33) in the moxibustion group and 0% (0/33) in the sham moxibustion group, with no statistically significant difference (P>0.05). CONCLUSION On the basis of lifestyle intervention, moxibustion effectively improves obesity-related physical indicators, enhances quality of life, alleviates anxiety and depression, and improves the phlegm-dampness constitution in patients with central obesity. These benefits persist for at least 4 weeks after treatment.

Objective: To investigate the genetic stability of virus seed H₂M₂₀K₇ (K7) of live attenuated Hepatitis A virus H2 strain (HAV, H2 strain) for production of hepatitis A (Live) vaccine, lyophilized after continuous passages. Methods: The virus seed K7 of H2 strain was proliferated and passaged in KMB₁₇ cells in cell factories. Viruses of different passages were harvested after continuous passages. Virus RNA was extracted and the complete genomes of different virus passages (K7, K10, K11, K13, K15, K18) were sequenced by using next-generation deep sequencing. The mutation rates of different passages were compared. The infectivity titers of different virus passages of H2 strain were tested by ELISA. Results: The mutation rates of complete genomes of different passages were low after continuous passages of master virus seed. The structure of gene was stable and non-synonymous mutation rate was lower than 0.57%. The mutation rate of 5 ’non-coding regions was lower than 0.1%. There was no significant mutation in VP1/2 A and 2C virulence site. The infectious titers of H2 strains of different passages were within 7.76-8.50 lgCCID₅₀/ml. No statistically significant difference was found in this study. Conclusions The gene structure of the master virus seed, working seed and different passages of H₂M₂₀K₇ after subculture was stable and the mutation rate was low. No significant mutation was found in 5’non-coding regions, and the critical virulence sites such as VP1/2 A, 2B and 2C showed attenuated characteristics with low mutation rate. Virulence of the virus did not changed. The H2 strain maintained stable viral infectivity and genetic stability and comply with the requirements as virus seed for vaccine manufacturing.

Objective To investigate and analyze the blood uric acid level and the detection rate of hyperuricemia (HUA) and to discuss its related risk factors. Methods From January to December 2016, physical and biochemical examination were conducted to a total of 7 585 cases with health examination, which were selected by using cluster sampling method. We analyzed the detection rate in percentage and the related factors of HUA by applying Pearson test and Logistic regression. Results Detection rate of HUA in this group was 32.76%, with 32.88% males and 32.69% females. The average blood uric acid level presented (358.98±91.11) μmol/L, of which male was (368.25±91.11) μmol/L and female was (343.13±91.12) μmol/L. Positive correlation was shown between blood uric acid levels and systolic blood pressure, diastolic blood pressure, BMI, total cholesterol, triglyceride, low density lipoprotein(LDL-C)(P＜ 0.05), while negative correlation was revealed between blood uric acid levels and high density lipoprotein(HDL-C)in both males and females (P＜ 0.05). The independent risk factors of HUA were high systolic blood pressure, high triglyceride and low LDL-C, and the protective factor was high HDL-C. Conclusions Hyperuricemia is often associated with high systolic pressure, hypertriglyceridemia and low LDL-C. Attention should be paid when it comes to health interventions in people with elevated serum uric acid level.

Purpose To identify the role of tyrosine kinase receptor Axl for anti-apoptosis which was induced by cisplatin (DDP) and methotrexate (MTX) chemotherapy and to analyze the relationship between P-Axl and apoptosis-related proteins in osteosarcoma.Methods Osteosarcoma cell lines MG63,143B and U2OS were used in apoptosis assays,Axl siRNA transfection,cytotoxicity assays,cell cycle analysis,etc.A total of 41 cases of osteosarcom patients were included for immunohistochemistry of EnVision two-step staining and clinico-pathological relative analysis.TUNEL assay was performed in ten cases for apoptosis detection.Results Among the osteosarcoma cell lines,Gas6/Axl could obviously protect tumor cells from apoptosis induced by DDP and MTX (P ＜ 0.05).Axl siRNA transfection enhanced cell apoptosis,whereas Gas6 prone to function upon previous knockdown by Axl siRNA.Among the 41 cases,the positive rate of P-Axl,BCL-2,and Bax was 85.4％,70.7％,and 36.6％,respectively.In contrast,the positive rate of them was 22.2％,11.1％,and 11.1％ in osteofibrous dysplasia,respectively.The expression levels of these apoptosisrelated factors were significantly higher in osteosarcoma than in osteofibrous dysplasia (P ＜ 0.05).Through clinico-pathological analysis,there were significant relationships between the survival status and BCL-2 or Bax expression (P ＜ 0.05).Pearson correlation analysis demonstrated that BCL-2 was positively correlated to P-Axl with statistical significance (r =0.842,P ＜ 0.0001).By Cox univariate analysis,BCL-2 or Bax was correlated with the patients' prognosis.TUNEL assay also demonstrated that P-Axl high expression inhibited apoptosis in osteosarcoma tissues.Conclusion Gas6/Axl protects osteosarcoma cells from the apoptosis induced by DDP and MTX chemotherapy and inhibits apoptosis in osteosarcoma tissue,possibly through the regulation of apoptosis-related protein BCL-2.
