Objective: To observe the effect of electroacupuncture (EA) combined with Stretta radiofrequency treatment on contents of motilin (MTL) and gastrin (GAS) in gastroesophageal reflux disease (GERD) patients.
Methods: A total of 90 eligible GERD cases were randomly allocated into three groups, 30 in each group. Patients in the EA group were treated with EA, patients in the radiofrequency group were treated with Stretta radiofrequency, and patients in the observation group were treated with EA combined with Stretta radiofrequency. Assessment was made after a course of treatment.
Results: The recovery, improvement and failure cases and total effective rate in the EAgroup were 2, 18, 10 and 67.7% respectively, versus 13, 13, 4 and 86.7% in the radiofrequency group and 20, 9, 1 and 96.7% in the observation group. The therapeutic efficacy in the observation group was significantly better than that in the other two groups (P<0.01). After treatment, symptom scores of regurgitation, heartburn and substernal burning pain in all three groups were significantly reduced (P<0.05); the reduction in the observation group was more significant than that inthe other two groups (P<0.05),and the reduction in the radiofrequency group was more significant than that in the EA group (P<0.05). After treatment, the contents of MTL and GAS in all three groups were increased; and the increase in the observation group was more significant than that in the other two groups (P<0.05).
Conclusion: EA combined with Stretta radiofrequency treatment can significantly improve the clinical effect of GERD patients, improve regurgitation, heartburn and substernal burning pain and increase the contents of MTL and GAS.

Objective To study the feasibility and curative effect of transumbilical single-incision (TSIL) vs multiple-incision (MIL) laparoscopic splenectomy.Methods Ten cases (2 cases of idiopathic thrombocytopenia purpura,1 case of hereditary spherocytosis,3 cases of splenic hemangioma and 4 cases of cirrhotic splenomegaly) underwent TSIL from Jan 2010 to Ju12011,and 12 cases (3 cases of ITP,2 cases of hereditary spherocytosis,3 cases of splenic hemangioma and 4 cases of splenomegaly) underwent MIL.Clinical data were compared with each other.Results No severe complications occurred in either group.The mean operation time of single-incision group and multiple-incision group was ( 182 ± 23 ) min and ( 169 ± 19) min,and blood loss was( 160 ± 13 ) ml and ( 155 ± 16) ml ( P ＞ 0.05 ).The post-operative pain score in TSIL and in MIL group was respectively [ ( 1.60 ± 0.20) vs (3.60 ± 0.90) on day 1,P ＜ 0.05 ; (0.50 ±0.10) vs (2.00 ±0.45) on day 2,P ＜0.05].There was no significant difference between the two groups in the recovery of the gastrointestinal function,the length of hospital stay and the cost of hospitalization, all P ＞ 0.05.The umbilical incision in TSIL cases is more cosmetic.Conclusions Transumbilical single-incision laparoscopic splenectomy is feasible and safe in experienced hands.

The efficacy of laparoscopic Dixon operation for the treatment of rectal cancer has been proven,while at the same time there are opportunities to make the procedure less invasive.From January 2010 to March 2011,9 cases of single access laparoscopic Dixon operation have been performed at the Shengjing Hospital.An incision with the length of 3 cm was created in umbilicus and 3 trocars were inserted through the fascia on the abdominal wall.The dissection and anastomosis were performed through the incision.The resected tumors were removed through the umbilical incision or anus.The operation was successfully performed on 9 patients,and one more incision with the length of 12 mm was created on the lower abdominal wall in 1 patient in order to install the stapling device.The average operation time was 202 minutes.No postoperative bleeding,intestinal obstruction or anastomosis leakage was found.

Objective To evaluate the effects of soy isoflavones on bone density (BMD) in women in randomized clinical trials by meta-analysis. Method We searched the databases the Medline, Pubmed, and CNKI from January 1990 to October 2007 using the keywords, phytoestrogen, isoflavone, soy, genistein in combination with bone. We only included the studies of randomized clinical trial, in which the data of BMDs at lumbar spine, total hip or femoral neck prior to and post isoflavone intervention or their relevant changes and their standard deviation or 95% CI in women were provided. Results Sixteen papers (1304 women, 91% postmenopausal) were included and a mean daily dose of 73 mg supplemental soy isoflavones resulted in weighted mean (%)(95%CI) difference in yearly BMD changes of 18.3 (2.0%,CI 6.0~30.6) and 3.3(0.40%,CI 0.5~6.1) mg/cm2 at the lumber spine and total hip, respectively. Subgroup analyses showed that the effects were more pronounced in those with the isoflavone dose ≥80 mg/d than those of

Objective: To analyze the epidemic trend of viral hepatitis in Nanjing from 1989 to 2019 and predict the incidence in 2020, so as to provide reference for the prevention and control of viral hepatitis. Methods: The incidence data of viral hepatitis in Nanjing from 1989 to 2019 was retrieved from Nanjng Center for Disease Control and Prevention and National Infectious Disease Reporting System. The epidemic trend was analyzed by estimating the annual percent change ( APC ) and the average annual percent change ( AAPC ). The seasonal incidence of different types of viral hepatitis was analyzed by seasonal index. The autoregressive integrated moving average model ( ARIMA ) was built to predict monthly incidence rate of viral hepatitis in 2020. Results: The annual incidence rate of viral hepatitis was 62.00/100 000 in Nanjing from 1989 to 2019, showing a downward trend ( AAPC=8.4%, P<0.05 ). From 1998 to 2019, the annual incidence rates of hepatitis A, B, C and E were 1.98/100 000, 14.31/100 000, 2.30/100 000 and 2.60/100 000. The incidence of hepatitis A and B showed downward trends ( AAPC=-11.81%, -6.02%, both P<0.05 ); the incidence trend of hepatitis C was not obvious ( P>0.05 ); the incidence of hepatitis E showed an increasing trend ( AAPC=4.82%, P<0.05 ). From 2015 to 2019, the third and fourth quarters were the epidemic seasons of hepatitis A, B and C, while the first and second quarters were the epidemic seasons of hepatitis E. The ARIMA model predicted that the monthly incidence rates of viral hepatitis in 2020 would range from 1.26/100 000 to 3.69/100 000, among which hepatitis B ranged from 1.21/100 000 to 2.58/100 000, hepatitis C from 0.20/100 000 to 0.48/100 000, hepatitis E from 0.09/100 000 to 0.25/100 000. Conclusions The incidence of viral hepatitis in Nanjing shows a downward trend. Among different types of hepatitis, hepatitis B has a higher incidence. All types of hepatitis have epidemic seasons. It is predicted that the monthly incidence rates of viral hepatitis will be 1.26/100 000 to 3.69/100 000 in 2020.

Objective To study the proliferation,collagen production and related gene expression in keloids and normal skin fibroblast.Methods Isolated primary cells of keloid fibroblasts (KFb,n=12) and normal human dermal fibroblasts (NFb,n=12) were identified,the cell viability and proliferating potential and the cell cycle were detected,and the difference on the collagen synthesis between KFb and NFb were compared.The expression of cell cycle-associated genes such as p21,p16,and p27 was dectected by real-time fluorescent quantitative PCR.Results The phase contrast optical microscopy imaging showed that both KFb isolated from keloid tissues and NFb from normal skin tissues possessed classic and similar fibroblast morphology.But there was a significant difference between cell proliferation,Hyp [(2.30±0.10) μg/ml vs.(1.66±0.13) μg/ml,P＜0.05] and collagen levels [(17.19±0.75) μg/ml vs.(12.37±0.94) μg/ml,P＜0.05].Compared with NFb,KFb exhibited more percentage of G2/M phase cells [(5.90±0.62)％ vs.(16.94 ％±1.93)％,P＜0.05]and less percentage of G0/G1 phase cells [(90.24 ±2.27)％ vs.(75.65±1.92)％,P＜0.05].Cell cycle related genes p16,p21 and p27 were low expressed.Collagen type Ⅰ was highly expressed at mRNA levels in KFb than that in NFb [0.84±0.11,1.32±0.2,1.69±0.12,4.33±0.27 in KFb vs.1.43±0.13,2.56±0.26,2.89±0.37,1.40±0.12 in NFb,P＜0.05].Conclusions There are cell dysfunction and abnormal cellular dynamics in keloid fibroblasts.The formation of keloid likely involves aberrant interactions of some genes that affected its development at different extents.
