Objective: To observe therapeutic effect of the method for tonifying the kidney and soothing the liver on impotence. Methods: 80 cases of impotence were randomly divided into a treatment group treated by Bushen Shugan Pills and a control group treated by Jingui Shenqi Pills. They were treated for 3 months and the International Erection Index Functional (IIEF-5)was determined at the end of 0,1,2,3 months after administration. Results:The total effective rate was 77. 5% in the treatment group and 52. 5% in the control group with a significant difference between the two groups (P

Objective To display whether Interleukin-8 was involved in acute lung injury(ALI) and in acute respiratory distress syndrome(ARDS).Methods Serum IL-8 levels in 12 patients with ALI and 13 patients with ARDS were assayed by RIA,and compared with 59 normal controls.Results The level of serum IL-8 was significantly higher in the patients with ALI and ARDS than that in the normal controls(P

Objective To analyze the endoscopic features of patients with the lower esophageal sphincter (LES) and crural diaphragm (CD) separation and explore its significance in hiatus hernia (HH) diagnosis.Methods From January 2011 to June 2012,the data of patients underwent esophagus high resolution manometry (HRM) examination were retrospectively analyzed and of which the patients with LES-CD separation were selected.Patients who received digestive tracts operation or lack of complete endoscopic date were excluded.A total of 93 cases were enrolled for analysis.According to Chicago Criteria,the cases were divided into three groups.There were 21 cases in type Ⅰ group (LES-CD separation＜1 cm),37 cases in type Ⅱ group (LES-CD separation≥l cm and ＜2 cm),35 cases in type Ⅲ group (LES-CD separation≥2 cm).The differences among groups in endoscopic features were analyzed.HRM were taken as golden standard,the sensitivity and specificity of endoscopy in HH diagnosis were analyzed.Measurement data were expressed as x ± s,one-way ANOVA was performed for multi-groups comparisons,LSD method or Dunnett T3 test for pairwise comparisons and chi-square test or Fisher's exact test for two groups' comparisons.Results There were no significant differences in the distance between esophagus gastric junction (EGJ) and foreteeth of the three groups (P＞0.05).Distances between EGJ and diaphragmatic HH pressure impression in type Ⅲ group,type Ⅱ group and type Ⅰ group were (3.57±0.78) cm,(1.89±0.81) cm and (1.14±0.67) cm,respectively and the differences were significant (LSDt=9.26,11.44,3.57; all P＜0.05).The percentage of continuously-open cardia and showing pressure impression of the gastric pouch of type Ⅲ group was higher than that of type Ⅱ group and the percentage of continuously-open cardia and showing pressure impression of gastric poach of type Ⅱ group was higher than that of type Ⅰ group (80.0％,40.5％ and 4.8％,x2 =11.64,29.76 and 8.59; 91.4％,27.0％ and 4.8％,x2 =30.69,40.73 and 4.32' all P＜0.05).The occurrence rates of the His angle blunting and sac of type Ⅲ group were higher than those of typeⅡ group and type Ⅰ group (74.3％ and 77.1％,24.3％ and 24.3％,4.8％ and 4.8％,x2 =17.97 and 25.41,both P＜0.05),there was no significant difference between type Ⅱ group and type Ⅰ group (P＞0.05).The rates of esophagitis of type Ⅲ group and type Ⅱ group were higher than that of type Ⅰ group (71.4％,59.5％ and 14.3％,x2 =17.14 and 11.15,both P＜0.05),there was no significant difference between type Ⅲ group and type Ⅱ group (P＞0.05).There was one case of Barrett's esophagus in each group.The sensitivity and specificity of endoscopy in HH diagnosis were 91.4％ and 81.0％,respectively.Conclusions The distance between EGJ and hiatal pressure impression,continuously-open cardia,the His angle blunting,hiatal pressure impression of the gastric pouch and hernia sac were important indicators of HH endoscopic features.The sensitivity of endosocopy is higher than the spcificity of endosocopy in HH diagnosis.

Objective To establish and identify the induced pluripotent stem cell(iPSC) line reprogrammed from human umbilical cord mesenchymal cells(HuMSCs).Methods HuMSCs were cultured by adhesion method,and OCT4,SOX2,KLF4,c-Myc,NANOG,LIN-28 were transfected into HuMSCs with lentiviral victor to reprogramme HuMSCs into iPSC.Morphological observation,pluripotency genes (SOX2,TDGF1,THY-1,OCT4,REX1 and TERF1) expression,alkaline phosphatase detection,karyotype analysis,embryonic stem cells (ESC) specific proteins (NANOG,OCT4,SSEA-4,TRA-1-81) immunofluorescence staining,differentiated into teratomas in vivo(inject the iPSC into SCID mice) and embryniod bodies in vitro were performed to exam the pluripotency of the iPSC.Results Four days after being infected by lentivirus,the HuMSCs became round-shape; 10 days after infection,some embryonic stem(ESC)-like colonies appeared.Fourteen days after infection,picked up the regularly shaped colonies and cultured several passages.About 1.25％ HuMSCs were reprogrammed into iPSC.The iPSC presented clone-like growth like ESC.All the cells were positive to alkaline phosphatase staining and expressed the pluripotency genes.The iPSC also expressed the ESC specific proteins,and karyotype analysis showed normal chromosome caryotype (46,XY).Furthermore,the iPSC could form embryoid bodies in vitro,expressed alpha fetoprotein(AFP),smooth muscle actin(SMA) and β-tubulin.The iPSC could alsoform teratomas in vivo.Conclusion OCT4,SOX2,KLF4,c-Myc,NANOG,LIN-28 can reprogram HuMSCs into iPSC efficiently.

Objective To compare the short term clinical efficacy of percutaneous resection and laparoscopic deroofing of renal cysts.Methods From October 2013 to June 2016,the data from 39 cases with renal cysts were followed for approximately 22 months (ranging 5-36 months).Patients were randomized into two groups.In the resectoscopic group(17 pts),the mean age of those patients was 57 years (ranging 34-81 years).The mean size of these cysts was 6.4cm (ranging 5.4-8.2 cm).The mean preoperative creatinine was 66.5μmol/L (ranging 38.1-108.8μ mol/L).The mean preoperative sodium was 141.4μ mol/L(ranging 135.6-145.1μmol/L).The mean preoperative potassium was 4.0μmol/L (ranging 3.4-4.7 μmol/L).In the latter laparoscope (22pts),the mean age of these patients was 60 years (ranging 46-73 years).The mean size of these cysts was 6.8cm (ranging 4.3-8.9cm).The mean preoperative creatinine was 74.8μmol/L (ranging 48.6-141.9μmol/L).The mean preoperative sodium was 141.5μmol/L(ranging 135.0-146.1 μmol/L).The mean preoperative potassium was 4.0μmol/L (ranging 3.1-4.8μmol/L).The operative time,blood loss,days of drainage,hospital stay and complications were compared with the two groups.Results All of the 39 cases were accepted the procedure successfully without open conversion.Compared the resectoscopic group with Laparoscopic,the mean operative time was 29.7 min (ranging 15-50 min) and 63.0min (ranging 20-1 00 min),mean blood loss was 36.6ml(ranging 10-80 ml) and 60.4ml(ranging 10-200 ml),days of drainage was 2.3 days and 3.1 days,hospital stay was 3.7 days and 5.1 days,the mean postoperative creatinine was 67.4 μmol/L(ranging 43.8-95.5 μmol/L) and 68.9μmol/L(ranging 46.5-157.6 μmol/L),the mean postoperative sodium was 141.2μmol/L(ranging 136.0-147.2 μmol/L) and 141.6 μmol/L(ranging 136.0-147.2 μmol/L),the mean postoperative potassium was 3.8 μmol/L (ranging 3.2-4.3 μmol/L) and 3.8μmol/L (ranging 3.3-4.3 μmol/L).The overall postoperative pathology was renal cysts.All cases were followed for approximately 19 months (ranging 6-35 months) and 22 months (ranging 5-36 months) in reseetoscopic and laparoscopic group respectively.No cysts recurrence was found by ultrasound.Conclusions Compared with laparoscopic deroofing,use of resectoscopic technology significantly enhances the possibility of achieving better intraoperative results in all patients with renal cysts.Percutaneous resection of simple renal cysts is safe and feasible.

Objective To investigate the clinical features,pathogenesis,diagnosis and treatment of neonatal cerebral infarction(NCI)in order to have a further understanding of its clinical features,to enhance therapeutic effica﹣cy and to improve prognosis. Methods The clinical history,head magnetic resonance imaging( MRI)+ diffusion Weighted imaging(DWI)data and folloW－up results of 39 neonates With NCI admitted into the Department of Neonato﹣logy,Gaozhou People＇s Hospital and the Second Affiliated Hospital of Shantou University Medical College from January 2013 to March 2018 Were retrospectively analyzed. Results All the 39 children Were diagnosed as NCI by MRI +DWI,among Which 30 cases(76. 92%)Were full－term infants,and 9 cases(23. 08%)Were premature infants,in Which 61. 54%(24／39 cases)Were males,and 17 cases(43. 59%)Were performed With emergency cesarean section because of umbilical cord around neck,intrauterine distress or maternal pregnancy hypertension respectively. TWenty－five patients(64. 10%)had the history of perinatal hypoxia. The presentation of MRI shoWed 32 cases(82. 10%)of ischemic cerebral infarction and 7 cases(17. 90%)of hemorrhagic cerebral infarction,While middle cerebral artery and its branches Were more susceptible to NCI With a left hemisphere predominance. Sixteen patients(41. 03%)developed convulsions. TWo patients died of purulent meningoencephalitis associated With NCI. One patient gave up treatment in the neonatal period and died 2 days after discharge. One patient died of cerebral palsy and pneumonia at the age of 11 months. Nine cases(31. 03%)developed cerebral palsy,and 2 patients developed speech disturbance so they could not express complex sentences. Conclusions Perinatal hypoxia and emergency cesarean section may be closely related to the incidence of NCI. NCI resulting from purulent meningoencephalitis is more severe and has a Worse prognosis. Considering the facts that NCI usually does not have specific clinical manifestations in the early stage,MRI +DWI,as the gold standard for the diagnosis of NCI,could be performed to facilitate early diagnosis and intervention.
