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 analyze relative risk factors of hyperamylasemia after open-heart surgery, and provide basis for clinical prevention and treatment. Methods: A total of 521 adult patients, who received open-heart surgery under general anesthesia and low temperature in our hospital from Jan 1, 2013 to Jun 30, 2013, were selected. The 2ml peripheral venous blood was taken in each patient instant after ICU hospitalization, 24h, 48h and 72h after surgery, then serum was separated and measured for serum amylase level by Somogyi method. According to the measured results of serum amylase level, patients were divided into hyperamylasemia group (serum amylase≥500U/dl, n=76) and non- hyperamylasemia group (serum amylase<500 U/dl, n=445). Single factor and gradual Logistic regression analysis were used to analyze risk factors of hyperamylasemia in patients after open-heart surgery. Results: Gradual Logistic regression analysis indicated that cardiopulmonary bypass (CPB) time and hypotension during operation, renal dysfunction and infection after operation were independent risk factors for postoperative hyperamylasemia (OR=1.02~4.12, P<0.05 or <0.01). Conclusion: During perioperative treatment of open-heart surgery, shortening CPB time, avoiding hypotension during surgery, protecting renal function and preventing infection may reduce morbidity of postoperative hyperamylasemia and improve prognosis of patients.

Objective To investigate the clinical efficacy of acupuncture plus ashi point pricking bloodletting in treating acute gouty arthritis.Methods Seventy patients with acute gouty arthritis were randomly allocated to a treatment group of 38 cases and a control group of 32 cases. The treatment group received acupuncture plus ashi point pricking bloodletting and the control group, routine medication. Blood uric acid and C reaction protein contents were measured in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups.Results There were statistically significant differences in blood uric acid and C reaction protein contents after one and two courses of treatment compared with before treatment in the two groups (P<0.01). After two courses of treatment, there was a statistically significant difference in comparing C reaction protein contents between the two groups (P<0.05). The total efficacy rate was 84.2% in the treatment group and 81.3% in the control group; there was a statistically significant difference between the two groups (P<0.05).Conclusion Acupuncture plus ashi point pricking bloodletting is an effective way to treat acute gouty arthritis.

Objective:The pathogenesis of endometriosis(EMT)was explored by detecting the relationship of progesterone receptors(PR)and apoptosis-associated factors with EMT.Methods:Immunohistochemical imaging analysis was used to quantify the expression of PR,Bcl-2 and Bax in ectopic and eutopic endometrium in patients with EMT.Results:Expressions of PR and Bcl-2 in eutopic endometrium are higher than those in ectopic endometrium(P<0.05).Expression of Bax in ectopic endometrium is higher than that in eutopic endometrium(P<0.05).There is no statistical difference of PR,Bcl-2 and Bax expression between proliferative and secretary endometrium.Conclusions:Either in proliferative or secretary phase,expressions of PR in eutopic endometrium are higher than those in ectopic endometrium,thus eutopic endometrium is more liable to proliferate in low level continuously,migrate and implant.Expressions of Bcl-2 and Bax in eutopic and ectopic endometrium have no relationship with endometrium cycling.The apoptosis of ectopic endometrium is weakened and its proliferative power is continuously enhanced.

In the experiments we used T_6 medium prepared by ourselves and mixed with diferent concentrations of human serum albumin or mother's serum, from which we prepared follicular flushing medium, insemination medium and growth medium. Clomiphene citrate and HCG were used for inducing superovulation. The semen was obtained through masturbation and artificially capacitated. A mature ovum and 2-3 drops of capacitated semen were incubated together in insemination medium in the culture box containing 5% CO_2 in air atmosphere at 37℃. The ovum was aspirated and transferred into the growth medium and incubated for 16-17 hours. By this time the ovum was already fertilized with the appearance of 2 pronuclei. About 30 hrs, it normally developed into two-cell stage, 40-44 hrs, it cleavaged into 4-cell stage. After 72 hrs, the fertilized ovum grew into morula. Up to June, 1986 twentythree ova in vitro fertilized and cultured were transfered into 14 mothers, uteri at the four-cell stage. The details of fertilization and the early embryo development in vitro were described.

Objective To investigate the change of serum cardiac troponin I(cTnI)following coronary artery bypass grafting.Methods 55 OPCABs and 55 cCABGs were performed.Serum cTnI were measured before operation(T1)and immediately after operation(T2)and 1d(T3),2d(T4),3d(T5),4d(T6),5d(T7),6d(T8),7d(T9),10d(T10),14d(T11).Results The serum cTnI level increased differently after OPCAB and cCABG and then returned to normal level gradually.The peak value of serum cTnI level in OPCAB was lower than that in cCABG.There were 9 cases on myocardial infarction,of which OPCAB 4 cases,cCABG 5 case,with serum cTnI level increasing;and there weren't death.Conclusion The serum cTnI in OPCAB and cCABG both increased and then decreased to normal level gradually.Measuring serum cTnI could diagnose myocardial injury and indicate prognosis.
