Objective: To investigate the role of intraoperative ultrasound(IOUS) and appropriate approach in local resection for the central small hepatocellular carcinoma(sHCC) which is deeply situated within the parenchyma and adjacent to the hepatic veins. Methods: under IOUS guidance, local resection was carried out for 8 cirrhotic patients with central sHCC which was deeply located and adjacent to hepatic veins by approach of splitting or unroofing superficial hepatic parenchyma. Results: All tumors were precisely localized by IOUS and excised successfully. Except for injury to central hepatic vein in 1 case, no other injury occurred to the hepatic veins in the remaining 7 cases. There was no postoperative mortality, and the liver function recovered well in all cases postoperatively. Conclusion: Local resection by using IOUS and appropriate approach is applicable for the cirrhotic patients with deeply located central sHCC. IOUS plays an important role in avoidance of injuries to the hepatic veins.

Objective To observe the safety and severity of heat-sensitive moxibustion in treating poisonous snakebites-induced bladder dysfunction of different degrees.Method Twenty-six patients diagnosed with bladder dysfunction due to poisonous snakebites were examined by type-B ultrasonic scanning for residual urine volume and uroflowmetry. The patients were treated with heat-sensitive moxibustion. The residual urine volume and uroflowmetry parameters were compared between different severity degrees of bladder dysfunction before and after treatment.Result The residual urine volumes were changed significantly in the mild group and moderate group after treatment (P<0.01); the residual urine volume showed insignificant change after treatment in the severe group (P>0.05). The maximum urine flow rate (Qmax) was significantly changed in the mild group after the treatment (P<0.05); the Qmax was insignificantly changed in the moderate and severe groups after treatment (P>0.05).Conclusion Heat-sensitive moxibustion is significantly effective in treating mild-moderate bladder dysfunction due to poisonous snakebites, and it’s safe and reliable.

BACKGROUND:An intensivestudy on ovarian cancer A2780 cels contributes to modify treatment strategies targeting ovarian cancer stem cels and enhance survival rate of ovarian cancer patients.
OBJECTIVE:To investigate the effects of umbilical cord blood mesenchymal stem cels (UC-MSCs) transplantation combined with paclitaxel on proliferation, apoptosis, and invasion of A2780 human ovarian cancer celsin vitro.
METHODS:A2780 human ovarian cancer cels were assigned into three groups: blank control group (routine cel culture),UC-MSCs group (addition of suspension containing 1×106UC-MSCs) and combined treatment group (combined addition of suspension containing 1×106UC-MSCs and 250μL of 1μmol/L paclitaxel solution). CD133+antigen expression, proliferation, apoptosis, and invasion were determined by immunofluorescent staining, flow cytometry, TUNEL staining, and Transwel chamber invasion assay, respectively.
RESULTS AND CONCLUSON:CD133+antigen expression intheUC-MSCs group and combined treatment group was significantly decreased compared withtheblank control group (P< 0.05). Proliferation and invasion abilities were significantly decreased, while apoptosis cel number was significantly increased inthecombined treatment group compared with the other two groups (P< 0.05). These findings indicate that the combined treatment of UC-MSCs transplantation and paclitaxel can inhibit proliferation and invasion and promote apoptosisof A2780 human ovarian cancer cels.

Objective To discuss the efficacy of Baofukang combined with clindamycin injection in treatment of chronic cervicitis patients with high-risk human papilloma virus infection (hr-HPV).Methods Totally 100 patients who had chronic cervicitis with hr-HPV were selected and divided into two groups randomly.The patients in control group (49 cases) were given Baofukang.The patients in observation group (51 cases) were given Baofukang combined with clindamycin injection.The efficacy of Baofukang combined with clindamycin injection in treatment of chronic cervicitis patients with hr-HPV was evaluated by efficacy,HPV negative rate,inflammatory factors before and after treatment and adverse reaction during treatment.Results After treatment,the effective rate of observation group was 92.1％,and the effective rate of control group was 75.5％,the effective rate of observation group was higher than that of control group (P ＜ 0.05).After treatment,the HPV negative rate in observation group was 90.2％,the control group was 59.2％,the HPV negative rate of observation group was higher than that of control group (P ＜ 0.05).Before treatment,there was no statistical significance on hs-CRP,IL-6,and TNF-α between two groups.After treatment,the hs-CRP,IL-6,and TNF-α were decreased in two groups (P ＜ 0.05).The hs-CRP,IL-6,and TNF-α of observation group were lower than those of control group (P ＜ 0.05).There was no statistical significance on adverse reaction between two groups.Conclusion Baofukang combined with clindamycin injection had a good therapeutic effect on chronic cervicitis with hr-HPV.It could inhibit HPV and inflammatory factors well.It was safe and worthy of clinical use.

BACKGROUND:Cancer related genes and pathways play a critical role in formation and development of cancer.
OBJECTIVE: To investigate the silencing epidermal fatty acid binding protein 5 (FABP-5) by siRNA interference on biological characteristics of the cervical carcinoma cel line SiHa.
METHODS:Design and synthesis of siRNA interference sequence used to transiently transfect SiHa cels was performed according to FABP-5 mRNA coding sequence. mRNA and protein expressions of FABP-5 were detected by RT-PCR and western blot assay, respectively. Meanwhile, cel cycle, proliferation, invasion and apoptosis were detected by flow cytometry, cel counting bit-8 assay, Boyden chamber assay, and TUNEL staining, respectively.
RESULTS AND CONCLUSION: FABP-5 mRNA and protein expressions, cel growth speed, cel number at S phase (cel cycle was arrested at the G0/G1 phase) and cel invasion were significantly decreased, while the cel apoptosis was significantly increased in FABP-5 siRNA group compared with the negative control and blank control groups. Our findings indicate that the specific silencing FABP-5 gene expression by siRNA interference can inhibit SiHa cervical cel growth and proliferation, but accelerate cel apoptosis.
