Objective To evaluate the clinical efficacy of four different methods of laparoscopic hysterectomy: laparoscopic supracervical hysterectomy(LSH),classic intrafascial supracervical hysterectomy(CISH),laparoscopic-assisted vaginal hysterectomy(LAVH),and total laparoscopic hysterectomy(TLH). Methods A retrospective analysis was carried out on 740 cases of laparoscopic hysterectomy in this hospital from January 1999 to December 2004 in respect of operating time,intraoperative blood loss,weight of removed uterus,postoperative recovery,time to normal sexual life,sexual satisfaction,and incidence of complications. Results The operations were accomplished under laparoscope in all the 740 cases.The operating time of LSH,CISH,TLH,and LAVH were 95.3?32.4 min,84.5?31.7 min,105.3?34.5 min,and 169.4?37.4 min,respectively.The time to normal sexual life of LSH,CISH,TLH,and LAVH were 30?5 d,50?9 d,35?7 d,and 54?11 d,respectively.The incidences of complications of LSH,CISH,TLH,and LAVH were 1.7%(2/120),1.3%(4/310),2.8%(7/250),and 1.7%(1/60),respectively. Conclusions Laparoscopic hysterectomy is safe and reliable.Of four methods of laparoscopic hysterectomy,each has its advantages and disadvantages,and method selection should be based on patient's own conditions.

Objective To retrospectively study the results of endoscopic manifestation pathology,and treatment of colonic polyps. Methods Clinical data of 121 patients diagnosed with colonic polyps and treated by endoscopy between November 2002 and September 2009 were studied. Complete colonic investigation was done by Olympus PCF240I electron endoscopy. Colonic polyp excision was done by high frequency electric coagulation. Results All patients had bloody stool with mucus for 1 week to 8 years. Ninty four(77.7%)patients had a single polyp,6(5.0%)had two polyps,21(17.3%)with multiple polyps,and 5 patients had familial polyposis coli. The size of the polyps ranged from 0.3 cm to 4 cm and the morphology of Yamada Ⅰ to Ⅳ. The pathological changes were juvenile polyps,inflammatory polyps,polypoid formation,and canalicular adenoma. Most common pathology types were Yamada Ⅳ and juvenile polyps,107 of the 121 patients(88.4%)had juvenile polyps,and one was found to have malignant transformation. 115 patients accepted high frequency electric coagulation excision under general anesthesia,without complication. Conclusions Colonic polyp is one of the common diseases in children. Children should be checked by total colonoscopy in time when they present with bloody stool,anemia,rectal polyps prolapse or intussusception. Polypectomy under endoscope is a most safe and reliable treatment method when the diagnosis is confirmed. For isolated juvenile polyp,regular recheck is not necessary after polypectomy except when bloody stool recurs. Regular follow up by colonoscope is necessary for juvenile polyp combined with adenoma and adenomatous polyps. Colonoscope is necessary at any time when bloody stool occurs. Familial polyposis coli is difficult to be treated by endoscopy,thus surgical procedure is suggested.

Objective To systematically compare the efficacy of three-dimensional conformal radiotherapy (3D-CRT) versus intensity-modulated radiotherapy (IMRT) in the treatment of prostate cancer (PCa).Methods Clinical comparative studies of IMRT and 3D-CRT in the treatment of PCa were collected from PubMed, EMBASE, China National Knowledge Infrastructure (CNKI), and Wanfang Data after two independent researchers developed the strategy and inclusion and exclusion criteria for the literature search.Articles published up to February 2017 were searched for, and the languages of publications were restricted to English and Chinese.Clinical meta-analysis of the data from the relevant studies was performed using the RevMan5.3 software.Results A total of 15 relevant retrospective cohort studies were collected from the databases in strict accordance to the search strategy and inclusion and excluding criteria.There were 4608 PCa patients, including 2229 in the IMRT group and 2379 in the 3D-CRT group.IMRT and 3D-CRT had similar adverse effects in terms of early-stage (odds ratio[OR]=0.77, 95% confidence interval[CI]:0.43-1.40, P=0.390) and late-stage (OR=0.75, 95%CI:0.55-1.04, P=0.080) urinary tract injury.However, IMRT led to reduced early-stage (OR=0.47, 95%CI:0.27-0.82, P=0.008) and late-stage (OR=0.52, 95%CI:0.35-0.78, P=0.001) intestinal injury compared with 3D-CRT.Meanwhile, the biochemical recurrence-free survival rate was also significantly higher in the IMRT group than in the 3D-CRT group (OR=1.87, 95%CI:1.51-2.32, P=0.000).Conclusions IMRT is more protective against intestinal injury with a higher biochemical recurrence-free survival rate compared with 3D-CRT during the treatment of PCa.

Objective_To investigate whether hUCMSCs undergo malignant transformation when exposed to MCF-7B breast cancer microenvironment and whether the abnormal activation and over expression of STAT3 play an impor-tant role in this transformation.Methods_The experiment was divided into three groups:blank group ( hUCMSCs were separately cultured),experimental group(hUCMSCs were indirectly co-cultured with MCF-7B breast cancer cells),positive control group(MCF-7B breast cancer cells were separately cultured).Morphology of cells was detec-ted by invertedmicroscope.Cell cycle was detected by flow cytometry.The mRNA expression of STAT3, c-Myc and Bcl-xL was tested by real-time PCR.The protein expression and location of p-STAT3,c-Myc and Bcl-xL were detected by immunofluorescence.The protein expressions of p-STAT3,STAT3,c-Myc and Bcl-xL were also meas-ured by Western blot.Results_The experimental group cells showed typical morphology of the tumor cells.The cells proportion of experiment group in G1 phase was significantly lower than that of the blank group(P<0.05),but which in S and G2 phase were significantly higher than those of the blank group(P<0.05).The mRNA expression levels of STAT3 ,c-Myc and Bcl-xL in experimental group was significantly higher than those in blank group ( P<0.05).p-STAT3,STAT3,c-Myc and Bcl-xL protein were significantly higher than those of the blank group(P<0.05),and they were mainly located in the nuclei.The protein expression of STATS also showed significant changes in experimental group.Conclusions_hUCMSCs trends to malignant transformations when exposed to MCF-7B breast cancer microenvironment.The abnormal activation and over expression of STAT3 are of important factors leading to the malignant transformation of hUCMSCs.

Objective To explore the protective effect of Red Sage Root on bronchopulmonary dysplasis(BPD) induced by hyperoxia in newborn rats.Methods On the 2nd postnatal day,SD newborn rats were randomly assigned to 4 groups:air and NS group(group Ⅰ),air and Red Sage Root group(group Ⅱ),hyperoxia and NS group(group Ⅲ),hyperoxia and Red Sage Root group(group Ⅳ).The rats in group Ⅲ and group Ⅳ were exposed to hyperoxia(the level of oxygen was 900-960 mL/L).The rats in group Ⅱ and group Ⅳ were injected with Red Sage Root intraperitoneally(10 mg/kg)daily.On 14 days after birth,6 rats in each group were killed.Lung histologic changes,radical alveolar counts(RAC)were monitored.Thiobarbituric acid method,nitrite method,2-nitroben zoic acid method were used to determine the concentration of malony ldialdengde(MDA),superoxidedismutase(SOD),glutathione peroxidase(GSH-Px) were monitored.Results 1.Group Ⅲ and group Ⅳ showed the inhibition of lung development and the evident lung fibrosis.In contrast to group Ⅰ and group Ⅱ,RAC in group Ⅲ and group Ⅳ decreased dramatically(Pa

Objective To evaluate the possibility and curative effect of total en bloc spondylectomy (TES) for the treatment of primary tumors of the lumbar spine. MethodsBetween June 2005 and July 2009,nine cases of primary tumor of the lumbar spine were treated with total en bloc spondylectomy through a single posterior approach performed in seven cases(L1 giant cell tumor, L1 osteosarcoma, L2 giant cell tumor,L2 solitary plasmacytoma, L2 chondrosarcoma, L2 chordoma, and L3 histiocytic sarcoma), and two cases through a single stage anterior and posterior combined approach (L4 giant cell tumor with paraspinal mass and L4 fibrosarcoma). They were performed a single stage reconstruction after removing tumors of vertebra. Neurofunction was evaluated perioperatively and recurrence of tumor was tracked for all cases.ResultsThe follow up was obtained for 3-49 months (averaging 19 months). All patients attained significant clinical improvement after surgery without any severe complications. There was no local recurrence and distal metastasis in shortterm follow-up. ConclusionThe treatment by TES to remove tumors and reconstruction of spine are reliable for primary tumors of the lumbar spine. The curative effect of short-term follow-up is satisfactory. However, the long-term curative effect remain to be further follow-up.

The paeonol proniosomes ointment and ordinary ointment were administered to rats. Physiological saline served as perfused solution. The perfusion rate was 5 mL x L(-1) and the microdialysis samples were collected every 20 min intervals. The paeonol concentration in perfused solution was determined by HPLC. Investigation of the pharmacokinetics of paeonol proniosomes ointment and ordinary ointment by the skin-blood synchronous microdialysis coupled with HPLC is reported in this study. The results show that the recovery was (54.80 +/- 1.50)% in vitro and (54.58 +/- 4.61)% in vivo. The results showed that paeonol proniosomes ointment significantly raised the drug concentrations in skin more than the paeonol ordinary ointment. The paeono proniosomes ointment has less drugs into the blood as the ordinary ointments in blood, but its blood drug concentrations were steadier. The paeonol proniosomes ointment may be developed into a new preparation.

OBJECTIVETo study the proliferation and differentiation of neural stem cells in the subventricular zone (SVZ) in neonatal rats after bilateral common arteries occlusion.

METHODSNinety-six 3-day-old Sparuge-Dawley rats were randomly divided into two groups: ischemia and control. Rats in the ischemia group were subjected to bilateral common arteries occlusion and the rats in the control group were sham-operated. All rats were administrated with 5-bromodeoxyuridine (BrdU) (50 mg/kg) via intraperitoneal injection. Rats were sacrificed and their brains were removed 1, 4, 7, 10, 14 and 35 days after ischemia. Using brain paraffin sections and immunofluorescence assays, the number of newborn cells in the SVZ was counted. Newborn neural stem cells and oligodendrocytes in the SVZ were observed, and then double marked with BrdU and nestin or osmium tetroxide (O4).

RESULTSThe number of BrdU+ cells (neural stem cells) in the SVZ in the ischemia group was greater than in the control group 4, 7, 10 and 14 days after ischemia, and reached a peak at 4 days after ischemia (253.1+/- 49.3 vs 133.5+/- 17.7; P< 0.01). By 35 days after ischemia, the number of BrdU+/O4+ cells (oligodendrocytes) in the corpus callosum (56.0+/- 7.2 vs 17.0+/- 6.4; P< 0.01), the septal nuclei (45.0+/- 11.9 vs 20.5+/- 5.0; P< 0.01), the striatum (34.5+/- 4.2 vs 14.5+/- 5.8; P< 0.01) and the olfactory bulb (46.5+/- 6.6 vs 23.5+/- 8.4; P< 0.01) in the ischemia group increased significantly as compared to the control group (P< 0.01).

CONCLUSIONSBrain ischemia can activate the proliferation of neural stem cells in the SVZ and promote neural stem cells differentiation into oligodendrocytes. The immature brain may have the capacity for self-repair after ischemic brain injury.
