OBJECTIVE: To evaluate the efficacy and safety of Chinese medicine (CM) improving pregnancy outcomes after surgery for endometriosis-associated infertility. METHODS: A multicenter, randomized, double-blind placebo parallel controlled clinical trial was designed. A total of 202 patients who had laparoscopy for endometriosis-associated infertility with qi stagnation and blood stasis syndrome were included and randomly divided into the CM treatment group and placebo control group at a ratio of 1:1 using a central block randomization from May 2014 to September 2017, 101 patients in each group. The two groups received continuous intervention at 1-5 days after surgery, for 6 menstrual cycles. Before ovulation, the CM group was treated Huoxue Xiaoyi Granule (); after ovulation, Bushen Zhuyun Granule ( was involved. The control group was treated with placebo. Transvaginal ultrasonography was performed every menstrual cycle during the treatment, and female hormone levels in the follicular and luteal phases were measured during the 1st, 3rd and 6th menstrual cycles. The analysis was continued until pregnancy. The primary outcomes were clinical pregnancy rate and pregnancy outcome, and the secondary outcomes were follicular development and endometrial receptivity. Safety evaluations were performed before and after treatment. RESULTS: (1) Clinical pregnancy and live birth rates: the clinical pregnancy and live birth rates of the CM group were significantly higher than those of the placebo group [44.6% (45/101) vs. 29.7% (30/101), 34.7% (35/101) vs. 20.8% (21/101), both P<0.05]. (2) Follicle development: the incidence of dominant follicles, rate of cumulative cycle ovulation, and rate of cumulative cycle mature follicle ovulation were significantly higher in the CM group than those in the placebo group [93.8% (350/373) vs. 89.5% (341/381), 80.4% (275/342) vs. 69.1% (253/366), 65.8% (181/275) vs 56.1% (142/253), P<0.05 or P<0.01]). The incidence of cumulative cycle luteinized unruptured follicle syndrome was significantly lower in the CM group than in the placebo group [11.7% (40/342) vs. 17.8% (65/366), P<0.05). (3) Endometrial receptivity: after treatment, both endometrial types and endometrial blood flow types in the CM group were mainly types A and B, while those in the placebo group were mainly types B and C, with a significant difference between the two groups (both P<0.05). (4) Adverse events: the incidence of adverse events between the two groups was not significantly different (P>0.05). CONCLUSION Strategies for activating blood circulation-regulating Gan (Liver)-tonifying Shen (Kidney) sequential therapy can effectively improve the clinical pregnancy rate and live birth rate of endometriosis-associated infertility with qi stagnation and blood stasis after laparoscopy, improve follicular development, promote ovulation, improve endometrial receptivity, while being a safe treatment option.

OBJECTIVE: The expression of microRNA-125b in tongue squamous cell carcinoma (TSCC) was detected and analyzed for its relationship with the clinicopathological features of TSCC. METHODS: Real time fluorescence-quantitative polymerase chain reaction (RT-qPCR) was used to detect the expression of microRNA-125b in 35 TSCC tissues and adjacent normal tissues from 35 TSCC cases. The relationship between the expression of microRNA-125b in TSCC tissues and the clinicopathological features of patients with TSCC was analyzed. In situ hybridization (ISH) was used to detect the expression level of microRNA-125b gene in the TSCC tissues and adjacent normal tissues. RESULTS: RT-qPCR results showed that the relative expression levels of microRNA-125b in the TSCC issues was 2.32±0.69, and that of normal tissues was 0.87±0.32. The statistical results showed that the expression level of microRNA-125b was significantly higher in the TSCC tissues than in the normal tissues (P<0.001). The expression level of microRNA-125b in the TSCC tissues was not significantly correlated with age, gender, pathological grade, and lymph node metastasis but was positively correlated with TNM stage. Patients with high TNM stage had high microRNA-125b expression levels (P<0.05). The ISH results showed that the expression levels of microRNA-125b in the TSCC tissues were 0.010±0.003, and that of normal tissues was 0.004±0.001. The expression levels of microRNA-125b in the 35 TSCC tissues were significantly higher than those in the normal tissues (P<0.05). CONCLUSIONS MicroRNA-125b is highly expressed in TSCC and associated with TNM stage, suggesting that high microRNA-125b expression may be involved in the development of TSCC.

OBJECTIVE: To calculate the imbalance degree (IBD) of left-right meridian (IBD-LRM), IBD of exterior-interior meridian (IBD-EIM) and IBD of hand-foot meridians (IBD-HFM) of impedance in extracellular fluid of cells in twelve meridians of healthy subjects, so as to provide foundation for meridian diagnosis. METHODS: A total of 31 healthy volunteers were enrolled and bioelectrical impedance spectroscopy (BIS) was applied. The constant current (from 1 to 100 kHz, 200 μA) was connected into the bilateral twelve meridians through two excitation electrodes with a distance of 10 cm. Two measuring electrodes, with an interval of 5 cm, were set in between the two excitation electrodes to collect the voltage amplitude and phase. The Cole-Cole curve fitting was used to calculate the impedance of extracellular fluid of cells in the twelve meridians; the IBD-LRM, IBD-EIM and IBD-HFM as well as their absolute values were calculated. RESULTS: The impedance of extracellular fluid in the left side was higher than that in right side in the large intestine meridian, the small intestine meridian and the bladder meridian (<0.05, <0.01). The mean value of IBD-LRM of extracellular fluid was (4.0±1.4) %; the mean value of absolute value of IBD-LRM was (15.0±1.1) %; the maximum absolute value of IBD-LRM was the bladder meridian. The mean value of IBD-EIM was (3.3±1.0) %; the mean value of absolute value of IBD-EIM was (17.9±1.6) %; the maximum absolute value of IBD-EIM was the bladder meridian and the kidney meridian. The impedance of extracellular fluid of hand meridian, hand meridian and hand meridian were lower than those of foot meridians. The mean value of IBD-HFM was (-2.6±1.1) %; the mean value of absolute value of IBD-HFM was (19.7±1.7) %; the maximum absolute value of IBD-HFM was meridian; the imbalance of meridians was greater than meridians. There were significant differences in impedance of extracellular fluid between left and right and between hands and feet (<0.05, <0.01). CONCLUSION The extracellular fluid of left-right meridians of healthy subjects is different, but the absolute value of IBD is low; the mean value of exterior meridian and interior meridian is very close, and the absolute value of IBD is medium; the impedance of the foot meridians are greater than the hand meridians, and the absolute value of IBD is relatively high.

OBJECTIVE: To compare the distribution characteristics of pressing sensitive acupoints on the body surface between bronchial asthma (BA) patients and healthy subjects, and to analyze the distribution rules of pressing sensitive acupoints in BA patients. METHODS: Seventy BA patients and 70 healthy subjects were selected in this study. The pressing sensitive acupoints were checked with finger pulp and marked on human nerve segment graph. The numbers of pressing sensitive acupoints were counted and the positional relationship between distribution of pressing sensitive acupoints and the position of meridians and nerve segment was observed. RESULTS: (1) The incidence rates of pressing sensitive acupoints in BA patients group and healthy subjects group were 91.4% (64/70) and 15.7% (11/70) respectively, and the BA patients group was higher than the healthy subjects group (<0.01). (2) The top 3 meridians with pressing sensitive acupoints occuring in BA patients were bladder meridian of foot-, lung meridian of hand- and large intestine meridian of hand-, and the most frequent pressing sensitive acupoints were Feishu（BL 13）, Xinshu（BL 15）, Chize（LU 5） and Jueyinshu (BL 14). (3) The pressing sensitive acupoints in BA patients were distributed mainly on C, C and T-T nerve segment. CONCLUSION Pressing sensitive acupoints have a close correlation with physical condition, and there is a close relation between pressing sensitive acupoints distribution and corresponding meridians and nerve segments in BA patients.

Objective The aim of the present study was to investigate the relationship between the intake of salt and salted food and the infection of Helicobacter pylori (Hp) among 40-69 years old local residents in a county with high gastric cancer risk in Anhui province. Methods From July 2015 to August 2018, we conducted a questionnaire and a serological test for Hp among 40-69 years old local residents in Lujiang county, Anhui province. The questionnaire focused on the consumptions of salt and salted food. The relationship between Hp infection and risk factors was analyzed by gender. Univariate and multivariate logistic regression analysis were used to analyze the relevant influencing factors. Results The Hp infection rate of total local residents was 50.07%. Among male subjects, age, body mass index(BMI), marital status, educational level, job, labor intensity and income had no link to Hp infection (all P>0.05). But among female subjects, BMI was associated with Hp infection ( 2=13.454,P=0.001). Besides, alcohol consumption was a risk factor for Hp infection in male subjects(OR=1.789，95% CI:1.188-2.694，P=0.003). But, high intake of salt and salted food had no effect on Hp infection after adjustment for alcohol consumption variable in men using multivariate analysis (all P>0.05). After adjusted for BMI variable among female individuals, high salt intake (≥9 g/day) (OR=1.462，95% CI:1.060-2.015，P=0.021) and the high salted food intake (≥1 times /day) were risk factors for Hp infection in women(OR=1.560，95% CI:1.021-2.383，P=0.040). Conclusions In one county with high gastric cancer risk in Anhui province, high salt intake (≥9 g/day) and high salted food intake (≥1 times/day) are risk factors for Hp infection among 40-69 years old female local residents.

Objective To explore the associations of body mass index (BMI), waist circumference (WC), waist height ratio (WHtR) and the prevalence of hypertension in elderly residents over 60 years in Baodi district, Tianjin. Methods Residents over 60 who underwent medical examinations in the Koudong Health Center, Baodi district, Tianjin, were all invited to participate in the study from April to May, 2018. Participants were asked to fill out structured questionnaires and undergo physical examinations. Stratified analysis and logistic regression analysis were applied to examine joint effects and interactions of BMI and WC (or WHtR) on the risk of hypertension. Results A total of 1 417 residents (83.75%) out of 1 692 residents participated in the study. The prevalence of hypertension in the participants was 46.36%. 66.50% of the participants were BMI overweight or obese. Participants with central obesity accounted for 74.66% (measured by the WC) and 75.38% (by the WHtR). Compared to the normal weight measured by the BMI or the WC, BMI overweight (OR=1.65, 95%CI: 1.19-2.30) or obesity (OR=3.41, 95%CI: 2.23-5.20) and WC central obesity (OR: 1.49, 95%CI: 1.00-2.23) were associated with increased risk of hypertension. The joint effects of BMI and WC (OR=2.49, 95%CI: 1.78-3.46), or BMI and WHtR (WHtR overweight: OR=2.05, 95%CI: 1.41-2.99; WHtR obesity: OR=2.37, 95%CI: 1.50-3.76) were greater than the single effect of the latter (WC overweight/obesity: OR=1.39, 95%CI: 0.90-2.15; WHtR overweight: OR=1.02, 95%CI: 0.62-1.66; WHtR obesity: OR=1.44, 95%CI：0.55-3.81). Conclusions Of the three indices, BMI is strongly correlated with the risk of hypertension. BMI overweight or obesity has enhanced the association of WC or WHtR and the risk of hypertension, suggesting that weight control in the normal range, especially measured by the BMI index, may prevent and control hypertension.

The study is to investigate effects of andrographolide on experimental autoimmune myocarditis (EAM). Lewis rats were immunized on day 0 with porcine cardiac myosin to establish EAM. The EAM rats were treated with either andrographolide (25, 50, 100 mg/kg/day) or vehicle for 21 days. An antigen-specific splenocytes proliferation assay was performed by using the cells from control rats immunized with cardiac myosin. Survival rates, myocardial pathology and myocardial functional parameters (left ventricle end-diastolic pressure, ± dP/dt and left ventricular internal dimension) of EAM rats received andrographolide were significantly improved. Andrographolide treatment caused an decrease in the infiltration of CD3⁺ and CD14⁺ positive cells in myocardial tissue. Moreover, andrographolide treatment caused a reduction in the plasma levels of tumor necrosis factor-alpha, interleukin-17 (IL-17) and myosin-antibody, and an increase in the level of IL-10 in EAM rats. Oral administration of andrographolide resulted in the decreased expression of p-PI3K, p-Akt without any change of PI3K and Akt. Further results indicate andrographolide significantly inhibited myosin-induced proliferation in splenocytes, and this effect was inhibited by co-treatment of SC79 (Akt activator). Our data indicate andrographolide inhibits development of EAM, and this beneficial effect may be due to powerful anti-inflammatory activity and inhibitory effect on PI3K/Akt pathway.

Vacuum sealing drainage (VSD) is frequently used in abdominal surgeries. However, relevant guidelines are rare. Chinese Trauma Surgeon Association organized a committee composed of 28 experts across China in July 2017, aiming to provide an evidence-based recommendation for the application of VSD in abdominal surgeries. Eleven questions regarding the use of VSD in abdominal surgeries were addressed: (1) which type of materials should be respectively chosen for the intraperitoneal cavity, retroperitoneal cavity and superficial incisions? (2) Can VSD be preventively used for a high-risk abdominal incision with primary suture? (3) Can VSD be used in severely contaminated/infected abdominal surgical sites? (4) Can VSD be used for temporary abdominal cavity closure under some special conditions such as severe abdominal trauma, infection, liver transplantation and intra-abdominal volume increment in abdominal compartment syndrome? (5) Can VSD be used in abdominal organ inflammation, injury, or postoperative drainage? (6) Can VSD be used in the treatment of intestinal fistula and pancreatic fistula? (7) Can VSD be used in the treatment of intra-abdominal and extra-peritoneal abscess? (8) Can VSD be used in the treatment of abdominal wall wounds, wound cavity, and defects? (9) Does VSD increase the risk of bleeding? (10) Does VSD increase the risk of intestinal wall injury? (11) Does VSD increase the risk of peritoneal adhesion? Focusing on these questions, evidence-based recommendations were given accordingly. VSD was strongly recommended regarding the questions 2-4. Weak recommendations were made regarding questions 1 and 5-11. Proper use of VSD in abdominal surgeries can lower the risk of infection in abdominal incisions with primary suture, treat severely contaminated/infected surgical sites and facilitate temporary abdominal cavity closure.
