Objective:This study aimed to assess the efficacy of comprehensive laparoscopic surgical staging in early-stage ovari-an cancer, and provide references for clinical practice and research. Methods: Electronic databases, such as Embase, Medline, Co-chrane Library, CBM, and CNKI, were searched for studies on comprehensive laparoscopic surgical staging versus comprehensive lapa-rotomic surgical staging. Other sources, such as related references, were also retrieved. The literature was screened according to inclu-sion criteria. Data were extracted from the selected references, and the quality of the included studies was assessed. This meta-analysis was performed using RevMan 5.2 software. Results:A total of 11 studies involving 591 cases were selected, of which 235 cases be-longed to the laparoscopy group and 356 belonged to the laparotomy group. No statistically significant differences were observed be-tween groups in age, body mass index, clinical stage, histological type, and histological grade. The laparoscopy group had less intraoper-ative blood loss, earlier general diet intake, less postoperative complications, and lower postoperative recurrence rate than the laparoto-my group. No statistically significant difference was observed between groups in operation time, pelvic lymph node number (apart from pelvic and para-aortic lymph nodes), mortality. Conclusion:The results of this systematic review show that laparoscopic surgical stag-ing of early-stage ovarian cancer demonstrated staging adequacy and accuracy that were similar to those of laparotomic surgical stag-ing. Based on the principle of minimal invasion and radical treatment to tumor, laparoscopy showed more favorable operative outcomes than laparotomy.

Objective To observe the clinical efficacy of Huoxue Rongluo Particles combined with acupuncture in the eight confluent points of spastic cerebral infarction paralysis and its effects on Glu and Asp levels of serum. Methods Totally 60 patients were divided into two groups: the experimental group and the control group. Both groups received basic Western medicine treatment, and the experimental group received Huoxue Rongluo Particles additionally, one dose a day for two times orally taken; Acupuncture was on eight confluent acupoint, every two days. 15 d is a treatment course, with 6 courses in total. Clinical spasticity index (CSI) and TCM symptom scores before treatment and the treatment of half month, 1 month, 3 months were observed. The levels of Glu and ASP in serum were detected, and TCM clinical efficacy was observed. Results The CSI score, levels of Glu and Asp in serum and TCM symptom scores of the patients after half-month, one-month, and three-month treatment were lower than those before treatment (P<0.05, P<0.01). There was no statistical significance in CSI score after half month treatment between the two groups (t=0.329, P=0.743). The CSI score in the experimental group after one-month and three-month treatment was lower than the control group (t=-2.636, P=0.024; t=-4.213, P=0.021). There was statistical significance in the levels of Glu and Asp between the two groups after half-month and one-month treatment (P<0.05, P<0.01). There was no statistical significance in the levels of Glu and Asp in the two groups after three-month treatment (P>0.05). The TCM symptom scores in experimental group was lower than the control group after half-month, one-month and three-month treatment (P<0.05). The total TCM effective rate was 86.67% (26/30) in experimental group, and 80.00% (24/30) in the control group, with the experimental group better than the control group (P<0.05). Conclusion Huoxue Rongluo Particles combined with acupuncture eight confluence acupoints in the treatment of spastic cerebral infarction paralyzed patients can relieve spasm degree, improve TCM clinical symptoms, which mechanism may be related to reducing serum excitatory neurotransmitters.

Objective To observe the influence of needling the Eight Confluent Points plus Huo Xue Rong Luo granules on the levels of gamma-aminobutyric acid (GABA) and glycine (Gly) in patients with spastic paralysis after cerebral infarction. Method Sixty patients with spastic paralysis after cerebral infarction were randomized into a treatment group and a control group, 3 0 cases each. The control group was intervened by basic treatment, while the treatment group was by Huo Xue Rong Luo granules plus acupuncture at the Eight Confluent Points in addition to the basic treatment, for 6 treatment courses in total. Before the treatment, and after half-a-month, 1-month, and 3-month treatments, the Chinese Stroke Scale (CSS) and activities of daily living (ADL) were evaluated, the levels of GABA and Gly were detected by using high performance liquid chromatography (HPLC), and the therapeutic efficacies were compared. Result After half-a-month treatment, the CSS score dropped significantly in both groups (P<0.01), and the between-group difference was statistically significant (P<0.01);the ADL score (Barthel Index score) increased markedly in both groups (P<0.01), and the between-group difference was statistically significant (P<0.01); the level of serum GABA increased significantly in both groups (P<0.05), and the between-group difference was statistically significant (P<0.05);the level of serum Gly rose up significantly in both groups (P<0.01), and the between-group difference was statistically significant (P<0.05). After 1-month treatment, the CSS score dropped significantly in both groups compared to that before treatment (P<0.01), and the inter-group difference was statistically significant (P<0.01);the ADL score increased significantly in both groups compared to that before treatment (P<0.01), and the inter-group difference was statistically significant (P<0.01);the levels of serum GABA and Gly increased markedly in both groups compared to that before treatment (P<0.01), and the inter-group differences were statistically significant (P<0.01). After 3-month treatment, the CSS score dropped significantly in both groups compared to that before treatment (P<0.01), and the inter-group difference was statistically significant (P<0.01);the ADL score increased significantly in both groups compared to that before treatment (P<0.01), and the inter-group difference was statistically significant (P<0.01); the levels of serum GABA and Gly increased markedly in both groups compared to that before treatment (P<0.05), approaching the normal levels, and the inter-group differences were statistically insignificant (P>0.05). Conclusion Needling the Eight Confluent Points plus Huo Xue Rong Luo granules is effective in treating spastic paralysis after cerebral infarction, which is plausibly associated with the up-regulation of inhibitory neurotransmitters (GABA and Gly).

Objective To analyse the clinico-pathologic characteristics,diagnosis,therapy and prognostic of small cell neuroendocrine carcinoma of the cervix(SCNCC).Methods The clinic-pathological features of 12 patients with SCNCC treated in Tumor Hospital of Guangxi Medical University,admitted during March 2006 to July 2010,were analyzed retrospectively.Results Of 12 patients,the mean age was 38.7 years(rang 28-57 years),6 had stages Ⅰ b1-Ⅱa,6 had stagesⅡb-Ⅳ.Among 8 patients(Ⅰ b1-Ⅲb)underwent surgery,4 of them received neoadjuvant chemotherapy,8 of them received adjuvant chemotherapy and(or)radiotherapy.All had greater than one-half stromal invasion,4 patients had positive pelvic lymph nodes metastases.The positive ratio of the chromogranin(CgA),synaptophysin,neuronspecific enolase(NSE),cytokeratins(CK),CD56 tested by immunohistochemical staining were 8/12,9/10,4/4,4/4,4/4,respectively.Median follow-up period was 3 months(1-22 months).Among 8 patients underwent surgery,2 patients developed lung metastases,1 patient developed liver and lung metastases,1 patient developed liver metastases concurrently with bone metastases,disease-free survival (DFS)were 3 months(Ⅰ b2 with positive lymph nodes),4.6 months(Ⅱ a),7 months(Ⅰ b1),17 months (Ⅰ b2);2 patient died(8.5 and 11.3 months,respectively)after surgery;4 patients are alive and show no evidence of disease.Among 4 patients untreated,1 patients received concurrent chemoradiation and are alive for 10.1 months.Two patient untreated(Ⅲb,Ⅳ)died after 0.6 and 1.3 months final diagnosis,respectively.One patient Was lost follow-up.Conclusions SCNCC is a highly malignant tumor with rare morbility,propensity for distant spread and dismal prognosis.Final diagnosis of SCNCC depends on pathomorphology and immunohistochemical analysis.Combined therapeutic modalities may in favor of survival in some patients.

ABSTRACT:Objective To explore the effects of miRNA-1246 (miR-1246)on cell proliferation,invasion and migration in human cervical squamous cell carcinoma (CSCC)cell line SiHa.Methods SiHa cells were assigned into 3 groups:miR-1246 analog group,miR-1246 antagonist group and control group.Transfection efficiency was determined.The MTT assay,transwell assay and wound healing assay were performed respectively to evaluate the proliferation,invasion and migration abilities of SiHa cells.Western blot was carried out to detect the expression of thrombospondin-2 (THBS2)before and after transfection.A THBS2 3’-UTR-containing dual luciferase plasmid was synthesized and co-transfected with miR-1246 into SiHa cells to observe the luciferase enzyme activity.Results MTT assay,transwell assay and wound healing assay revealed that the abilities of proliferation,migration and invasion were significantly enhanced (P<0.01)in SiHa cells transfected with miR-1246 analog,but suppressed in SiHa cells transfected with miR-1246 antagonist.Western blot showed that SiHa cells transfected with miR-1246 analog had significantly decreased THBS2 expression (gray value = 6 .2 8 ± 1 0 .2 2 , P=0 .0 1 3 ) while those transfected with miR-1246 antagonist had significantly increased THBS2 expression (gray value = 12.90±19.81, P=0.037).After co-transfected with miR-1246 and THBS2 3’-UTR-containing plasmid,SiHa cells exhibited a decreased level of luciferase enzyme expression.Conclusion miR-1246 promoted the proliferation,invasion and migration of CSCC SiHa cell, and it might promote CSCC tumorigenesis and progression by suppressing the expression of its target gene THBS2 .

Objective To compare intraoperative,pathologic,postoperative outcomes and quality of life of laparoscopic radical hysterectomy and pelvic lymphadenectomy ( LRH + LPL) with abdominal radical hysterectomy and pelvic lymphadenectomy ( ARH + APL) for patients with early-stage cervical cancer.Methods The consecutive cases with International Federation of Gynecology and Obstetrics (FIGO) stages Ⅰ a2 - Ⅱ a cervical cancer who underwent surgery from Jan.1,2002 to Jan.1,2011 were documented,including 85 patients underwent LRH + LPL,and 85 patients underwent ARH + APL as control group.The clinical data of intraoperative,pathologic,postoperative outcomes and quality of life were compared between two groups.Survival data were estimated using Kaplan-Meier survival curves and compared with the log-rank test.Cox proportional hazards model was used for multivariate analysis.Results All but 2 surgical procedures were completed laparoscopically because of right common ihac vein vessel injuries.Mean operative time,it was longer for LRH + LPL than that for ARH + APL [ (242 ±74) minutes vs.( 190 ±61 ) minutes,P =0.000 ].Mean recovery time of intestines function was less for LRH + LPL than that for ARH + APL [ (45 ± 7 ) hours vs.(63 ± 1 1 ) hours,P =0.000 ].Mean estimated blood loss was less for LRH + LPL than that for ARH + APL[ (367 ±252) ml vs.(460 ±220) ml,P =0.006].Mean recovery time of urinary function was less that for LRH + LPL than that for ARH + APL [ ( 19 ±4) days vs.(21 ±4) days,P =0.000 ].There were no significant difference in numbers of the pelvic lymph nodes resected,the extent of parametrial tissue,vaginal cuff,negative margins obtained and complications.The median follow-up was 32 months (range 4 to 105 months),there was no significant difference in the recurrence rate (7％ vs.5％,P=0.540) and mortality rate (7％ vs.5％,P=0.540),5 years disease-free survival(90％ vs.94％,P =0.812),5 years over survival ( 90％ vs.95％,P =0.532 ).There were not significant difference in quality of life between ARH + APL group and LRH + LPL group( P ＞ 0.05 ).Only lympho-vascular space invasion was an independent prognostic factor by multivariate analysis (P =0.016).Conclusions For early stage cervical cancer,LRH + LPL has similar outcomes compared with ARH + APL.Laparoscopic treatment by experienced surgeons should be an ideal altemative.

Objective To investigate the clinical outcomes in the treatment of complex acetabular fractures through a single supra-ilioinguinal approach after the application of preoperative 3D printing and rapid prototyping simulating the operative procedure.Methods From January 2013 to January 2016,24 cases of complex pelvic and acetabular fractures in our hospital were retrospectively analyzed.Among them 18 cases were male and 6 were female.The average age was 39.2+±13.8 years (range,24-68 years).According to Letoumel-Judet's classification,there were 6 cases of transverse,4 cases of T shaped,4 cases of combined anterior column and posterior hemi-transverse (ACPHT) and 10 cases of 2-column fractures.The time from injured to operation averaged 9 days (range,4-18 days).Before operation,pelvic AP view,three-dimensional CT as well as CTA of iliac blood vessels was taken routinely in all cases.The CT and CTA scan data were then imported into Mimics software for 3D reconstruction.Surgical simulation and optimal placement of internal fixations were performed on computer.After that,the individual simulated model of the pelvis was printed by the use of 3D printing and rapid prototyping technique.The order of reduction,selection and optimal position of the implants were determined.The plates were bent before operation and the length and direction of the screws were recorded.A uniform supra-ilioinguinal approach was used in all cases.Results The length of incision averaged 9 cm (range,8-13 cm).The operative time average 130 min (range,90-220 min).The blood loss averaged 600 ml (range,300-1 500 ml).Once a satisfactory reduction was obtained,single placement of the plates was achieved.In accordance with the preoperative plan,the plates were perfectly fitted to the bone surface.The 24 patients were followed for an average time of 18.3 months (range,15-30 months).The fractures healed in all cases.The average healing time was 4.2 months (range,3-6 months).According to Matta criteria,there were 16 cases of excellent,6 cases of good,2 cases of poor and the excellent rate was 91.7％ (22/24).The average modified Merle d'Aubigne score was 16.5 (range,13-18).The functional outcome was excellent in 13 cases,good in 6 cases and poor in 5 cases.The excellent rate of hip functions was 79.2％ (19/24).There were 2 cases of femoral lateral cutaneous nerve injury (recovered one month later) and another 1 case of fat liquefaction of the incision happened three days postoperatively (the wound healed completely after several dressing changes).No inguinal hernia or abdominal wall hemias was found.No other postoperative complications was found.Conclusion The application of 3D printing and rapid prototyping technique allows preoperatively simulating reduction in vitro,determining the optimal position of the implants,bending the plates and measuring the length of the screws in advance,which could largely reduce the operative time,intraoperative blood loss and occurrence of postoperative complications.Adopting supra-ilioinguinal approach for the treatment of complex acetabular fractures with a small incision and less trauma,a full exposure could be obtained,so the reduction and fixation of the anterior,posterior and middle column (also named pubo-ischiatic column) could be completed in a direct visualization,resulting in a satisfactory clinical outcomes.

Objective To explore the relationship between hormone therapy (HT) in women withovarian malignancy and prognosis. Methods HT was used in 31 patients with ovarian cancer after surgery,and 44 eases with ovarian eaneer served as controL The expression of estrogen receptor (ER)α, ERβ andprogesterone receptor (PR) was detected by immunohistoehemieal staining respectively. The level of serumealeitonin and transforming growth factor α (TGFα) was detected by radio-immune and enzyme-linkedimmunosorbent assay pre- or post-surgery, as well as half a year to one year later post-surgery respectively inthese eases. The survival curve of Kaplan-Meier and log-rank test as well as scale risk of Cox model wereused to analyze the relationship between HT and prognosis of ovarian cancer. Results ( 1 ) The results oflog-rank test showed that there was no difference in survival curve of patients with or without HT [ (1108±52), (1086±43) d; P=0.940] ; the results of scale risk of Cox model also showed that HT was not anindependent prognosis factor for patients with HT. (2) There was no relationship with HT and theaccumulated survival in patients with either positive or negative expression of ERa, ERβ and PR in tissue;as well as between HT and the level of serum TGFα pre-, post-surgery, or half a year to one year aftersurgery. (3) The level of serum caleitonin in patients without HT post-surgery half a year to one year laterwas higher than that pre-surgery [ (141±13), (95±11) μg/; P<0.05], but there was no significantdifference between patients with HT half a year to one year later past-surgery and pre-surgery [ (90±18)μg/L, (93±14) μ/L; P>0.05]. (4) There was a significant difference in body and emotion function between HT and without HT groups [(1.84±1.50), (1.45±0.82); (12.69±10.20), (12.90±11.61); P<0.05], as well as in sex quality and autonomic nerve maladjustment and in the special listmade [(1.05±0.74), (1.77±1.08); (10.10±3.21), (13.09±4.30); P<0.05]. ConclusionsThere is no adverse influence on prognosis in using of HT for patients with ovarian cancer after surgery. HTfor patients with ovarian cancer post-surgery can help keep a stable level of scmm calcitonin as well asimprove the quality of life.

Objective To understand the elonal expansion and genetic diversity of Salmonella en-terica semtype Paratyphi A (SPA) and to construct a typing method to determine the epidemic clones of the isolates. Methods Antimicrobial susceptibility testing was performed with 3980 SPA isolates by the cen-trolled Kirby-Bauer disc diffusion technique on Muller-Hinton agar plates. A total of 15 SPA with nalidixie acid resistance for mutations in gyrA, gyrB, gyrC and gyrE genes within the quinolone-resistant determina-tion region (QRDR) were examined. Subtyping of 121 isolates of SPA from seven counties in Yuxi were studied using pulsed-field gel eleetrophoresis (PFGE) analysis following digestion of chromosomal DNA with restriction endanucleases Spe Ⅰ and Xba Ⅰ. PFGE patterns were analyzed by duster analysis. Results The nalidixic acid-susceptible isolates predominated in 1999 but was replaced by nalidixic acid -resistant (NAR) isolates after 2000. Amplification by PCR and sequencing of the genes with subsets of 15 NAR strains re-vealed that the resistance mechanisms had resulted from single point mutations in the gyrA gene. Spe Ⅰ and Xba Ⅰ digestion of 121 isolates gave five and four different PFGE patterns with the predominance of the Spe Ⅰ 01 and Spe Ⅰ 02 (or the Xba Ⅰ 01) epidemic patterns, respectively. Spe Ⅰ 01 and Spe Ⅰ 02 consisted of 37.2% and 57.9% of isolates, respectively, or Xba Ⅰ 01 consisted of 95.0% of isolates. Conclusion The incidence of resistance to nalidixic acid of the isolates increased during the study period. PFGE patterns Spe Ⅰ 01 and Spe Ⅰ 02 (or Xba Ⅰ 01), the main clones of the epidemics, are highly prevalent in Yuxi. PFGE with Spe Ⅰ and Xba Ⅰ is a useful technique to differentiate SPA.

Objective: To study the effect of lentivirus-mediated microRNA (miR) -1246 RNA interference (RNAi) on biological characteristics and behaviors in cervical cancer cells as well as to identify the downstream signaling pathways affected. Methods: MiR-1246 specific cDNA was synthesized and cloned into the recombinant lentiviral vector (LV-miR-1246-inhibitor) . The SiHa cells were devided into three groups: no viral infection (negative control, NC) , infection with control virus (LV-NC) , and infection with miR-1246-inhibitor virus (LV-miR-1246-inhibitor) . The expression of the miR-1246 was detected by reverse transcription (RT) -PCR. Cell growth was analyzed by cell counting kit 8 (CCK-8) assay. The invasion was dectected by transwell matrige gel. Cell apoptosis was detected by flow cytometer. The growth of xenograft tumors was also investigated. Expression of thrombospondin-2 (THBS2) , matrix metalloproteinase (MMP) 2, 9 were also evaluated in the cells. Results: (1) The expression level of miR-1246 in SiHa cells (0.11±0.13) was significantly lower in group LV-miR-1246-inhibitor than those in the group LV-NC and the group NC (1.14±0.86 and 1.30±0.73, respectively; P<0.01) . (2) The proliferation of SiHa was also markedly suppressed in CCK-8 at 96 hours (P<0.01) . (3) The number of group LV-miR-1246-inhibitor was significantly less than those in the LV-NC and NC groups in transwell invasion assay (71±4, 162±5 and 188±5, respectively; P<0.01) . (4) The apoptosis rate of SiHa cells in the group LV-miR-1246-inhibitor [ (16.10±3.37) %] was significantly lower than those of group LV-NC and group NC [ (5.67±0.89) % and (1.78±0.08) %,P<0.01]. (5) The tumor volume in the nude mice group LV-miR-1246-inhibitor [ (287±59) mm³] was significantly lower than those in the LV-NC and NC groups [ (571±137) and (657±144) mm³, respectively; P<0.01]. (6) Compared with the LV-NC group and the NC group, THBS2 protein expression in the tumor tissue of the nude mice in the group LV-miR-1246-inhibitor was significantly increased (P<0.05) , while the expression levels of MMP-2 and MMP-9 protein were significantly decreased (P<0.01) . Conclusion These results suggest that miR-1246 functions during cervical cancer pathogenesis and tumor formation via the THBS2, MMP signaling pathway.
