OBJECTIVETo study the effects of Kuntai Capsule (KTC), a Chinese herbal preparation, on the quality of life (QOL), breast distending pain and vaginal bleeding in women at early stage of menopause.

METHODSA total of 104 women at early stage of menopause, 54 had their uterus existed (Ue) and 50 in-existed (Ui), were enrolled, and they were randomized to the KTC group and the control group, with equal cases of Ue and Ui in each. The KTC group was treated with KTC 4 capsules twice a day; the control group treated with premarin 0.45 mg per day and for those of Ue 2 mg medroxyprogesterone additionally, with the remedies medicated orally for 1 year. All the testees were asked to record everyday their own condition of breast pain and vaginal bleeding and followed-up every 3 months to fulfill the Menopause Specific Quality of Life questionnaire. Ultrasonic examination on pelvis and breast as well as endocrine hormone assays of estradiol (E2) and follicle-stimulating hormone (FSH) were performed before and after the medication term.

RESULTSEffects of treatment in the two groups were different insignificantly in terms of QOL. The women were benefited in vasomotor and physical domains from the 3rd month of medication, and the psychosocial domain was also improved (for Ui initiating from the 3rd month and for Ue from the 6th month). In the domain of sexual life, KTC showed its favorable effect only on Ue beginning from the 9th month, but not on Ui; while all subjects in the control group had their sexual life improved from the 3rd month. In domain of breast pain, the occurrence at various time points between the two groups was insignificantly different, only that the severity in Ue of the control group was more significant from the 1st to 3rd month than that in the KTC group. As for the domain of vaginal bleeding, the uterine membrane was basically normal in both groups either before or after medication, but the incidence and lasting days from the 1st to 3rd month in Ue of the KTC group were significantly lower than those of the control group. Levels of E2 and FSH were not significantly changed after medication in the KTC group, while in the control group, E2 significantly increased and FSH significantly decreased in the women of Ue (P <0.05).

CONCLUSIONKTC could evidently improve the QOL of women at the early stage of menopause, and is of high safety, with less adverse reaction of breast pain and vaginal bleeding, and shows few impact on sexual hormones.

Objective To investigate the awaken effect of naloxon on dexmedetomidine anesthetized mice and its mechanism. Methods Thirty Kunming mice of clean grade were randomly divided into 3 groups which included NAL group (Naloxon group), ATI group(Atipamezole group)and NS group (Normal Saline group). All groups were given dexme?detomidine 1 mg·kg-1 intraperitoneally. Naloxon 2 mg·kg-1, atipamezole 2 mg·kg-1 and normal saline 10 mL·kg-1 were ran?domly given intraperitoneally to the NAL, ATI and NS group respectively 90 minutes after dexmedetomidine administration. At timepoints prior to dexmedetomidine administration and 5, 15, 30, 60, 90, 95, 105, 120, 180 minutes after it, the sedative and analgesic effects besides recovery time (based on restore of righting reflex loss) were assessed. Results Sedation and analgesia effects became apparent within 5 minutes, and peaked at approximately 60 minutes then spontaneously recovered at 180 minutes after injection of dexmedetomidine. The sedative and analgesic effects were reduced in both ATI and NAL groups. Compared with ATI group, the sedation scores were higher at 95, 105 and 120 minutes after dexmedetomidine admin?istration than those in NAL group (P<0.05) but the scores were not statistically significant at 180 minutes between these two groups. Compared with NS group, the sedation scores were lower at time points of 95, 105, 120 and 180 minutes than those in NAL group (P>0.05). The analgesic scores were not statistically significant at time points of 95, 105, 120 and 180 min?utes between NAL group and ATI group, but they were lower in NAL group compared with NS group at timepoints of 95, 105 and 120 minutes (P>0.05). The recovery time in ATI and NAL group were shorter than that in NS group (F=1 793.368, P<0.05), but it showed no statistical difference between ATI group and NAL group (P>0.05). Conclusion Naloxone had a certain awaken effect on dexmedetomidine anesthetized mice.

Objective To observe the expressions of OPN, COX-2 and CyclinD1 in breast infiltrating carcinoma and evaluate their relationships with clinic pathological features. Methods Expression of the above three indexes were detected from 70 breast cancinoma patients by immunohistochemistry. The relationships among them and clinicopathological features were analyzed. Results The positive expression rates of OPN were 78.8% in cases (≤45 years old) and 73.0% in cases (> 45 years old); the positive expression rates were 79.3%(tumor diameter ≤ 3 cm) and 73.2% (tumor diameter > 3 cm); the positive expression rates were 77.8%, 73.8% and 78.9% in cases ofⅠgrade, Ⅱgrade and Ⅲ respectively, the positive rates had no statistical significances(P > 0.05). The expression rates of OPN in cases of breast infiltrating carcinoma without and with axillary node metastasis were 62.5% and 93.3%, in cases at stage Ⅰ~Ⅱ and Ⅲ ~Ⅳ were, 68.0% and 95.0% respectively, the positive rates had statistical significances(P < 0.05). The expression of OPN was negatively correlated with ER and PR while positively correlated with CerbB2, COX-2 and CyclinD1. Conclusions OPN plays an important role in the invasion and metastasis of breast carcinoma coordinated with COX-2 and CyclinD1.

Objective To investigate the effects of sevoflurane pretreatment on renal ischemia-reperfusion (I/R)-induced apoptosis in kidney in rats. Methods Thirty pathogen-free male SD rats weighing 220-260 g were randomized into 3 groups (n=10 each):group control (group C);group I/R and group sevoflurane(group S). Renal I/R was induced by clamping the left renal pedicle for 45 min in I/R and S groups. In group S inhalation of 2.2% sevoflurane in O2 was started at 30 min before operation and maintained throughout the experiment.Venous blood samples were taken at 3 h of reperfusion for determination of serum BUN and Cr concentrations. The animals were then sacrificed and the left kidneys were removed for microscopic examination, detection of apoptosis(by TUNEL)and determination of heme oxygenase-1(HO-1) mRNA and protein expression (by RT-PCR and Western blot).Results Renal I/R significantly increased serum BUN and Cr concentrations, apoptotic index(percentage of apoptotic cells) and the severity of necrosis of renal proximal convoluted tubules (0=normal,4=necrosis of whole segment of proximal convoluted tubules).Sevoflurane inhalation attenuated the I/R-induced changes mentioned above.HO-1 mRNA and protein expression was up-regulated by I/R and HO-1 mRNA expression was further up-regulated by sevoflurane inhalation.Conclusion Sevoflurane pretreatment can protect kidney against I/R injury by attenuating cell apoptosis.Up-regulation of HO-1 mRNA expression may be involved in the mechanism.

Aim To establish insulin resistance cell model on HepG2 cells (human embryonic liver tumor cells )and investigate the effect of berberine hydro-chloride on insulin-resistant HepG2 (IR-HepG2 ) cells.Methods ① IR model was induced by respec-tively using 10 -9 ,10 -8 ,10 -7 ,10 -6 ,10 -5 ,10 -4 mol ·L-1 insulin with 25 mmol · L-1 glucose in HepG2 cells.② HepG2 cells were incubated with 2-NBDG (fluorescent labeled glucose)in a series of concentra-tion:50,100,200,400,600,800 μmol·L-1 and a series of incubation time:20,40,60,80,100 min, to select the optimum concentration of insulin and the optimum incubation concentration and time of 2-NBDG in HepG2 cells.The success of the model was deter-mined by detecting the consumption of glucose in the cell supernatant and the uptake of glucose in HepG2 cells.③To study the effect of berberine hydrochloride on improving insulin resistance on the cell level,met-formin and berberine hydrochloride were used in the IR cells.Results Six concentrations of insulin induced the IR model in different degrees.Although 10 -4, 10 -5 mol·L-1 insulin was significant,a large amount of cells died.10 -6 mol·L-1 insulin was effective and had high survival rate of HepG2 cells,which had sta-tistical significance compared with the normal group. When the incubation concentration of 2-NBDG was more than 100 mol·L-1 ,the fluorescence intensity of the cells was significantly different from the normal group.When the incubation time of 2-NBDG was more than 20 min,fluorescence intensity was significantly different from the normal group.When the incubation time of 2-NBDG was more than 100 min,the fluores-cence quenching phenomenon was obvious in the cells. Berberine hydrochloride and metformin significantly in-creased the glucose consumption and glucose uptake in cell supernatant, which had statistical significance compared with the model group.Conclusions Using 10 -6 mol · L-1 insulin induced IR model in HepG2 cells,the optimum incubation concentration and incu-bation time of 2-NBDG is 200 μmol·L-1 and 80 min, respectively.Berberine hydrochloride and metformin have obvious effect on improving IR in HepG2 cells.

Objective To summarize our experience in the modified total cystectomy and neobladder in patients with invasive bladder cancer.Methods Twenty one male patients with invasive bladder cancer were treated with modified total cystectomy and neobladder.Reconstruction of the lower urinary tract using modifiled ileal neobladder(in 17 patients)and sigmoid neobladder(in 4 patients)were performed.The median age of the patients was 62 years.The patients were followed up for 1-4 years.Clinical outcomes of these patients was evaluated,including the function of the neobladder,urinary function,renal function,serum electrolytes and QOL.Results There was no surgical mortality.The operating time was 3.5-6.5 h(mean,4.5 h).Blood transfusion was required in 4 cases.Fifteen patients(97 ％ had voluntary control of urination at daytime and 6 at night.They were functional to control urination 3-6 months after operation.Hydronephrosis to certain extent occurred in 5 patients,but was recovered after 6-8 months.There were one case of intestinal obstruction and one case of metabolic acidosis.Residual urinary volume was 30 ml in 1 cases and 40 ml in another.Conclusions Modified total cystectomy and neobladder is an ideal technique to treat invasive bladder cancer with good clinical outcomes of tumor control,high life quality,few severe complications and good urination control.

Objective To investigate the incidence of postoperative intubation-related complications and the need for measurement and adjustment of cuff-pressure of endotracheal tube. Methods Five hundred and nine patients of either sex undergoing elective surgery under general anesthesia with tracheal intubation were divided into 2 groups: control group (group C)and cuff-pressure measured group (group CPM). Operation time and duration of endotracheal tube were recorded. Twenty patients with the duration of endotracheal tube 120-180 min in each group were selected. Their tracheal mucous membrane was examined by fiberoptic bronchoscopy at the time of withdrawal of endotracheal tube. Postoperative complications including cough and bloody sputum were also recorded at 24 h after extubation. Results The two groups were comparable with respect to age, sex, operation time and the duration of endotracheal tube. The incidence of sore throat and bloody sputum was significantly higher in group C than in CPM group. The incidence of sore throat and bloody sputum was significantly increased as the duration of endotracheal tube was prolonged in control group while in CPM group only the incidence of sore throat was increased. Varying degrees of injuries to tracheal mucous membrane were observed with fiberoptic bronchoscope.The injuries were more serious in group C than in CPM group. Conclusion Measurement of intracuff pressure is helpful for reducing the tracheal intubation-related complications.
