Objective:To observe the clinical curative effects of sequential therapy of estrogen and progesterone in the patient after second curettage with residual uterine cavity. Methods:Totally 60 patients after second curettage with residual uterine cavity were ran-domly divided into the treatment group (30 cases) and the control group (30 cases). The treatment group was treated by sequential therapy of estrogen and progesterone,while the control group was selected curettage and treated with Xinshenghua granules, and the treatment course was 21 days. The serum level ofβ-human chorionic gonadotropin (β-HCG) , stop time of vaginal bleeding, menstrual restore time and clinical curative effect were evaluated and compared between the two groups. Results:After the treatment, the serum level of β-HCG, stop time of vaginal bleeding and menstrual restore time in the treatment group were lower than those in the control group (P<0. 05, P<0. 01). The clinical effective rate of the treatment group was 90%, while that of the control group was 93. 33%, and there was no statistically significant difference between the two groups (P>0. 05). Conclusion:The sequential therapy of estro-gen and progesterone can improve clinical symptoms and promote the functional recovery of uterus, which is worthy of clinical promo-tion.

ObjectiveTo investigate the diagnostic value and prognostic significance of plasma soluble triggering receptor-1 on myeloid cells ( sTREM-1 ) in patients with sepsis in the early stage.MethodsA total of 56 patients with systemic inflammatory response syndrome (SIRS) were enrolled for prospective and control study from May 2009 through July 2010. According to the criteria of sepsis set by SCCN/ESICM/ACCP/ATS/SIS in 2001, patients were divided into sepsis group ( n = 32), SIRS group (n = 24) . Meanwhile, 25 non-SIRS patients were enrolled in the control group. The sepsis group was further divided into two subgroups, namely survival subgroup and non-survival subgroup according to 28-day outcomes. The sTREM-1, procalcitonin (PCT), C-reactive protein (CRP), white blood cell count and neutrophil percentage count (NPC) were measured and APACHE Ⅱ scores were determined within 24 hours after admission. The correlation between sTREM-1 and APACHE Ⅱ score was analyzed. Quantitative data were analyzed by using F-test or Kruskal-Wallis test. ResultsThe plasma level of sTREM-1 in patients of sepsis group was significantly higher than that in SIRS group and control group [215. 1 (157.9 ～397.3) ng/L vs 103.6 (89.4 ～ 176.2) ng/L vs 33.6 (26.2 ～ 43.0) ng/L, P＜0. 05]. The plasma level of sTREM-1 in non-survival group was significantly higher than that in survival group[360.5 (262.2～434.5) ng/L vs 204. 1 (175.0～269.6) ng/L, P=0.002]. In sepsis group, the plasma level of sTREM-1 was positively correlated with APACHE Ⅱ score ( r, = 0. 426, P = 0. 032 ) The area under the ROC curve of sTREM-1 was 0. 935, larger than that of PCT and CRP. Conclusions Plasma sTREM-1 is a useful marker in diagnosis of sepsis at early stage. The increase in the level of sTREM-1 during the first 24 hours might be correlated with poor outcome of patients with sepsis.

ObjectiveTo counsel the life style from the first trimester based on the fasting hyperglysemia to decrease the rate of GDM and adverse effect of it. MethodsThe pregnancy women with fasting hyperglysemia were recruited. All subjects were divided into two groups, one was counselled the life style from the first trimester but the other not. The pregnant outcome were compared. ResultsIn the study group 1 100 with complete information and 29 were abnormal glucose intolerance, 1 120 of 47 in control. The rate of GDM or GIGT,hypertensive disease,spontaneous abortion,premature dilivery, polyhydramnios, fetal macrosomia, fetal growth restriction, neonatal respiratory distress syndrome and the mean GHbA1c was lower than that in control ( x2 = 8.110,6.124,5.815,4.518,6.355,3.957,5.453,4.619, t = 3.385, all P ＜ 0. 05 ). But the body mass index at labor( t = 0.698 ), infection disease ( x2 =0.082),mean neonatal weight (t = 2.09 )and neonatal hypoglysemia (x2 = 0.035 )of term labor had no significant differences. ( t = 0.698, χ2 = 0.082,t = 2.090, χ2 = 0.035, all P ＞ 0.05 ). ConclusionCounseling the life style from the first trimester based on the fasting hyperglysemia could decrease the rate of GDM or GIGT and improve the pregnancy result.

Objective To investigate the surface sterilization and modification of medical poly(tetrafluoroethylene)(PTFE) by remote argon plasma.Methods Carrier quantitative bactericidal test was used to examine the germicidal effect(GE) of the E.coli on the surface of medical PTFE film and surface structure,performances of sterilized PTFE were characterized by the water contact angle,mass loss and X-ray photoelectron spectroscopy(XPS).Results Both remote and conventional argon plasmas could sterilize effectively(GE≥3.769) in the conditions of plasma RF power 100 W,exposure time 120 s and argon flux 20 cm3/min.Remote argon plasma sterilization made the PTFE surface have higher hydrophilicity(?=58.5?) than the conventional argon plasma sterilization(?=70.5?) and did not cause remarkable degradation and damages in terms of the mass loss(mass loss was 11.8%).Remote argon plasma sterilization could enhance interaction reactions with argon radicals relative to those with electron and argon ions,thereby contributing more effectively to defluorination(F/C=2.24) from the PTFE than the conventional argon plasma sterilization(F/C=2.49) and more effectively to the formation of oxygen functionalities on the PTFE surface.Conclusion Remote argon plasma can inactivate E.coli effectively and at the same time bring better surface modification of PTFE.

Objective To investigate the value of lapa ro scopic surgery in the diagnosis and treatment of bile duct diseases in newborns and infants. Methods Clinical records of 9 newborns or infants with bile duct diseases diagnosed and treated under laparoscope from January 20 03 to August 2004 in this hospital were reviewed retrospectively. Resul ts Laparoscopic exploration in the 9 cases found 2 cases of congenital choledochal cyst, 5 cases of biliary atresia, 1 case of cholestasis, and 1 case of congenital bile duct hypoplasia. Cholangiography was successfully performed i n 8 cases. Two patients with choledochal cyst received an excision of the cyst a nd Roux-en-Y hepatico-jejunostomy. Among the 5 patients with biliary atresia, he patic porto-enterostomy was performed via open approach in 3 patients and via la paroscopic approach in 1, and surgery was refused in 1 patient. Open hepatic por to-enterostomy was also used in the patient with bile duct hypoplasia. The patie nt with cholestasis underwent a biliary tract irrigation. Conclusions Laparoscopy is simple and reliable in the diagnosis of bile duct disease s in newborns and infants. For the treatment of bile duct diseases, laparoscopic techniques have advantages of minimal invasion, good cosmetic results, less blo od loss, quick recovery, and reliable clinical effects.

Objective To explore the feasibility of tw o- port laparoscopy in the treatment of congenital hypertrophic pyloric stenosis. Methods A total of 21 infants with confirmatively diagnosed con genital hypertrophic pyloric stenosis were given a two-port laparoscopic pylorom yotomy. The procedure was performed using two trocars: a 5 mm trocar at the lowe r border of the umbilical ring was placed for the insertion of camera, and a 3 m m trocar was introduced below the costal margin at the midclavicular line to pas s the hook electrode and curved forceps. Results No conversion s to open surgery were required. The operation time was 23~65 min (mean, 31.3 mi n). The patients were discharged from hospital at 4~6 postoperative days. No com plications occurred. Follow-up for 2~7 months (mean, 3.2 months) showed a norma l development in all the 21 patients. Conclusions Two-port lap aroscopic treameat for congenital hypertrophic pyloric stenosis in infants is ef fective.

Objective To explore the causes and treatment of the complications after laparoscopic surgery in neonate and infants.Methods From January 2003 to June 2007,totally 287 neonates and infants received laparoscopic surgeries in our hospital, 10 of them developed postoperative complications.Results The complications included 7 cases of gastric mucosa rupture during pyloric resection,1 case of delayed rupture of the pylorus,1 case of intestinal malrotation complicated with duodenal stenosis,and 1 case of incisional hernia.The former 9 cases were cured by open surgery,and the last one recovered spontaneously in 4 months. Conclusions Mucosarupture caused by pyloric resection is the most common complication after laparoscopic surgery in neonates and infants,open surgery should be performed in such a situation.Delayed rupture of the bowel after laparoscopic surgery can be potentially fatal,and should be treated as soon as possible.Intestinal malrotation may lead to a high rate of malformation,which can be avoided by early diagnosis and treatment.

Objective To explore the values of combined detection of serumhuman epididymis protein E4 , CA125 and CA199 in diagnosis of endometrial cancer. Methods 118 patients with endometrial cancer were chosen as group A, 82 patients with benign uterine disease were assigned to group B. Serum levels of HE4, CA125 and CA199 were detected and the positive rates were compared between the two groups. Results Serum levels of HE4, CA125, and CA199, the positive rate were significantly higher in group A than in group B (P <0.05). HE4 positive rate was highest in group A, and group B had no HE4-positive patients. The sensitivity and accuracy of HE4 + CA125 + CA199 were the highest, which was 94.9% and 92.5%. Levels of HE4, CA125 and CA199 and positive rate showed a rising trend as FIGO stage increased (P < 0.05), and HE4 positive rate was significantly higher than those of CA125 and CA199 (P < 0.05). Conclusions HE4 can be used to identify benign and malignant diseases in the uterus , and has a higher diagnostic value of endometrial cancer as compared with CA125 and CA199. Combined detection of HE4, CA125 and CA199 can improve the positive rate and diagnosis accuracy in endometrial cancer.
