ABSTRACT
Objective To explore the application of carbon nanoparticles for tracing sentinel node(SN) in early gastric cancer (EGC).Methods Forty-six patients with EGC conducted subserous injection of carbon nanoparticle solution 1.0 mL at 4-6 points around tumor during operation.SN was examined by adopting 3 different methods.The first stained lymph node was defined as the first SN(FSN),and the whole group lymph nodes were identified as the group SN(GSN) and all lymph nodes colored within 5 min were labeled as the all SN(ASN).The affirmative SN and other resected lymph nodes were performed the histopathological examination and comparison.Resnlts In all 46 cases,SN was successfully detected out with the detection rate of 100％;the number of SN,GSN and ASN were 1.04 ± 0.21,3.93-±-1.90 and 13.61 ± 4.36 respectively,the difference in SN number among 3 different methods had statistical significance(P＜0.05).The accuracy rates of FSN,GSN and ASN for judging perigastric lymph node metastasis status were 95.65％,100％ and 100％,respectively.Conclusion The carbon nanoparticles tracing SN in EGC has higher staining rate and higher accuracy for predicting lymph node metastasis;GSN has high accuracy,moreover has less trauma and is most suitable method for detecting SN.
ABSTRACT
OBJECTIVE:To investigate the effects of Fluorouracil implants on intraperitoneal chemotherapy safety of advanced gastric cancer patients. METHODS:The information of 264 patients with advanced gastric cancer were analyzed retrospectively. All patients were given Fluorouracil implants 800 mg,scattered into the mesenteric and surgical area,dose of each implantation site less than 200 mg,the distance of implantation range from incision and anastomosis more than 3 cm. All patients were given second generation cephalosporin 30 min before operation,at 3rd h during operation,1-3 d after operation. The occurrence of complications and ADR during hospitalization were observed after operation. RESULTS:After operation,6 patients suffered from complications, with incidence of 2.28%,including 3 cases of gastrointestinal reaction,2 cases of anastomotic bleeding and 1 case of anastomotic leakage. Routine blood test and liver and kidney function were rechecked 3 d after operation,mainly thrombocytopenia and liver function injury,with the incidence of 2.65%. CONCLUSIONS:Fluorouracil implants can be used for intraperitoneal chemotherapy of advanced gastric cancer patients. However,attention should be paid to thrombocytopenia and liver function injury.
ABSTRACT
OBJECTIVE:To observe clinical efficacy and safety of triptorelin acetate in the treatment of endometriosis after lap-aroscopy. METHODS:196 cases of endometriosis were randomly divided into experimental group and control group with 98 cases in each group according to admission sequence. Both groups received laparoscopic surgery. After surgery,experimental group was given triptorelin acetate by intramuscular injection,3.75 mg/time,every 4 weeks;control group was given gestrinone orally,2.5 mg/time,twice a week,for 5 months. The ovulation,menstrual recovery and the occurrence of ADR were observed in 2 groups. The endometriosis relapse of 2 groups were followed up for 1 year and observed. RESULTS:After treatment,the ovulation recov-ery time and menstrual recovery time of experimental group were all shorter than those of control group,with statistical signifi-cance(P<0.05). The incidence of ADR in experimental group(17.34%)was significantly lower than in control group(35.71%), with statistical significance(P<0.05). During follow-up period,the relapse rate of experimental group(7.14%)was significantly lower than that of control group(18.37%),with statistical significance(P<0.05). CONCLUSIONS:After laparoscopic surgery, triptorelin acetate can significantly improve therapeutic efficacy of endometriosis,reduce the occurrence of ADR.
ABSTRACT
Objective To investigate factors that correlated to compliance of treatment in infertile patients with polycystic ovary syndrome (PCOS) to provide basis for clinical treatment, specialist consultation and health education. Methods Compliance was assessed by a questionnaire designed by reference to Morisky-Green test and therapeutic principles for PCOS. Interviews were performed in 128 infertile patients with PCOS in Renmin Hospital of Wuhan University, Wuhan, Hubei in China during March 2009 to September 2010. Data were analyzed with logistic regression. Results Logistic regression analysis revealed that a total of 41 (34.2% ) of 120 participants investigated showed good compliance. Factors that might significantly (P ＜ 0.05 ) correlate compliance of treatment included body mass index (BMI) of the patients ( OR = 2.426, 95% CI = 1.428 - 4.121 ), length of their marriage ( OR = 0.398, 95% CI =0.225 - 0.704) and their concerns for adverse drug reactions ( OR= 0.216, 95% CI = 0.067 - 0.694).Conclusions Patients with obesity, shorter length of marriage and concerns for adverse drug reactions show lower compliance. Publicity and intervention to those patients should be strengthened in clinics to improve their treatment compliance in patients with PCOS.
