Objective To explore the feasibility of laparoscopic operations in the treatment of ovarian benign tumors. Methods A retrospective analysis of 150 cases of ovarian benign tumors treated by laparoscopic surgery (146 cases of oophorocystectomy and 4 cases of adnexectomy) from January 1997 to October 2003 was made. Results Surgery was completed successfully in all the 150 cases and no conversions to open surgery were required. Mild extraperitoneal emphysema was observed in 2 cases and no other complications occurred. The mean blood loss was 100 ml, the mean operation time was 80 min, and the mean length of hospitalization was 4 3 days. A total of 128 cases were followed up for a mean of 3 8 years. Recurrence was found in 4 cases in 38 cases of endometriosis cysts. Among 15 patients complicated with infertility, conception occurred in 6 patients after surgery, with a pregnancy rate of 40%. Conclusions Laparoscopic surgery is safe and effective for ovarian benign tumors provided patients are properly selected.

Objective To discuss the clinical characteristics and treatment of amenorrhea caused by Tripterygium Wilfordii polyglycoside (TWP).Methods The sexual hormone levels of 25 outpatients of The First Affliated Hospital Of Wenzhou Medical College who suffered from secondary amenorrhea after the use of TWP were examined before and after the hormone therapy.In addition,the clinical presentations were observed.Results (1)The E2 level went down lower than 73.2pmol/L while FSH went up higher than 40U/L in all the 25 patients.Among them,24 patients were confirmed of the diagnosis of premature ovarian failure.⑵HT is an effective way for 20 patients.The total efficiency of the therapy was 80%.⑶The E2 secreted by ovary was higher (63.19?10.81)pmol/l vs. (365.45?161.60) pmol/L and FSH(110.72?21.52)U/L vs. 11.46?17.70)U/Lsecreted by pituitary was lower after therapy than before.⑷After the second period of therapy, the clinical perimenopausal symptoms of all the patients were improved to different degrees.Conclusion TWP may result in the disorders of ovarian functions, but and HT in time may be an effective therapy.

To explore the protective effects of trimetazidine on vascular endothelial cells injury induced by hydrogen peroxide (H2O2) and its pharmacological mechanisms of anti-oxidation.Methods Human umbilical vein endothelial cells (HUVECs) were injured by H2O2.Next,the cells were treated with three different concentrations of trimetazidine (1 μmol/L,10 μmol/L,100μmol/L,respectively).The viability of cells was detected by methyl thiazoeyl tetrazolium (MTT) assay.In addition,malondialdehyde (MDA)contents,superoxide dismutase (SOD) and secretion of NO were measured.Results Trimetazidine could enhance the viability of the injured HUVECs induced by oxidation,decrease the level of MDA,enhance the SOD activity,and increase the secretion of nitrogen monoxide.These effects were in a certain dose-dependent manner and the difference was significant among the three concentrations (P＜0.05).Conclusions Our results suggest that trimctazidine may protect lipid peroxidation and prevent oxidation-induced cellular dysfunction of HUVECs (J Geriatr Cardiol 2008;5:248-251)

The clinical date of 5 adult patients with severe tetanus admitted in the ICU of Jiangsu Provincial Subei People′s Hospital between October 2019 and January 2021 were analyzed retrospectively. There were 2 males and 3 females, aged 19-65 years. Patients had a history of trauma 5 to 30 days before the onset of the disease, and were admitted 1 to 11 days after the onset of the disease. The main manifestations were neck pain with limited movement, difficulty in opening the mouth, paroxysomal convulsions of the neck and both upper limbs, generalized paroxysomal convulsions or abdominal muscle tension, and abdominal pain. At the time of admission, the wounds of 2 patients had healed. After admission, all patients were treated with local debridement, metronidazole combined with penicillin/cephalosporin for anti-infection, and human tetanus immunoglobulin (HTIG) 3 000 U was injected into the gluteus and deltoid muscles to neutralize the free toxin in the body. Midazolam combined with magnesium sulfate was intravenously infused to control and relieve skeletal muscle spasm.Among them, 3 patients received tracheotomy and ventilation due to respiratory failure. One patient underwent bedside continuous renal replacement therapy (CRRT) for severe skeletal muscle spasm resulting in rhabdomyolysis syndrome and acute kidney injury. All five patients with severe tetanus were cured and discharged.

Objective:To study the effect of different crystalloid resuscitation on renal function in septic shock rabbits, and to provide a theoretical basis for the choice of crystalloid for clinical fluid resuscitation.Methods:Thirty-six healthy male New Zealand white rabbits were divided into six groups by random number table: control group, model group, and four crystalloid groups including normal saline (NS) group, lactate Ringer solution (LR) group, acetate Ringer solution (AR) group, and sodium potassium magnesium calcium glucose injection (SPMCG) group, with 6 rabbits in each group. Rabbits were infused with Escherichia coli lipopolysaccharide (LPS) 500 μg/kg via the marginal ear vein (infused at a constant speed within 20 minutes), and then continued to infuse in an increase of 300 μg/kg every 10 minutes, the maximum dose was 2 mg/kg, until the mean arterial pressure (MAP) dropped to 60% of the basal value, the septic shock model was considered to be successfully reproduced. The rabbits in the control group were not injected with LPS, and other operations were the same as in the model group. Different crystalloid groups were given crystal solution immediately after modeling for resuscitation (predetermined fluid volume 60 mL/kg, transfusion within 3 hours). The volume stress test was performed every hour to guide the fluid volume, and the stroke volume index increase rate (ΔSVI) < 15% was the end point of resuscitation. The control group and the model group were given NS 4 mL·kg -1·h -1 to maintain the physiological requirement. All groups were given tracheotomy and mechanical ventilation, and the hemodynamic changes were monitored by pulse-indicated continuous cardiac output (PiCCO). The dynamic changes of hemodynamic indexes, arterial blood gas analysis, electrolytes, blood glucose and renal function biomarkers were monitored before modeling, immediately after modeling and 3, 6, and 12 hours after resuscitation. Results:① Hemodynamic indicators: after modeling, the MAP in the model group and the four fluid resuscitation groups decreased significantly, the cardiac index (CI) increased, and the systemic vascular resistance index (SVRI), global end-diastolic volumn index (GEDVI) decreased. After different crystalloid resuscitation at different time points, MAP, SVRI, and GEDVI increased in the four crystalloid groups. ②Arterial blood gas analysis, electrolytes, blood glucose: blood lactic acid (Lac) in the model group and the four fluid resuscitation groups increased after model success. After fluid resuscitation, the Lac of each crystalloid group began to decrease and reached to the lowest at 12 hours. Compared with the LR, AR and SPMCG groups, the pH value decreased in the NS group at 6 hours and 12 hours of fluid resuscitation (6 hours: 7.29±0.00 vs. 7.40±0.02, 7.35±0.02, 7.37±0.02; 12 hours: 7.27±0.02 vs. 7.38±0.02, 7.39±0.02, 7.35±0.01; all P < 0.05). After fluid resuscitation, blood Cl - levels at 3, 6, and 12 hours in the NS group were significantly higher than those in the LR, AR and SPMCG groups (mmol/L: 113.4±0.6 vs. 101.4±3.6, 108.0±1.1, 106.0±0.8 at 3 hours; 115.1±2.0 vs. 101.1±2.7, 109.0±2.2, 105.3±0.6 at 6 hours; 116.9±0.1 vs. 104.2±4.4, 107.6±1.7, 108.7±0.6 at 12 hours; all P < 0.05). There was no significant difference in blood glucose at each time point among the four crystalloid groups. ③ Biomarkers of renal function: blood and urine neutrophil gelatinase associated lipocalin (NGAL) and cystatin C (Cys C) were significantly increased in the model group and four fluid resuscitation groups. After fluid resuscitation, blood, urine NGAL and Cys C decreased. There was no significant difference in blood, urine NGAL and Cys C at all the time points among the different fluid resuscitation groups. Conclusions:In the rabbit model of septic shock induced by Escherichia coli LPS, hyperchloremia and acidosis occurred after NS resucitation, but did not occur during the recovery of LR, AR and SPMCG. There was no difference in the effects of different crystalloid resuscitation on renal function in septic shock rabbits.
