Objective To investigate feasibility of ovarian preservation in early youth endometrial cancer (EC).Methods We searched the database.All the calculations and statistical tests were performed with the Revman 5.2 software.The odds risk (OR) of cancer recurrence or death was taken as observation index.Results The experimental group was compared to control group,the risks of relapse and death were similar.The combined OR of all relapse risk was 0.87 with a 95％ of confidence interval (0.44 ～ 1.70).While the combined OR of all death risk was 0.70 with a 95％ of confidence interval (0.42 ～ 1.15).Conclusions The present data show that ovarian preservation in early youth EC is feasible because the treatment can not increase the risks of relapse and death.However,this conclusion needs to be further confirmed with high-quality randomized clinical trials.

It has been widely accepted in modern pharmaceutical industry that quality cannot be tested into products , instead quality should be built-in by design . However , the implementation of Quality by Design ( QbD ) in development , manufacture and supervision of traditional Chinese medicine ( TCM ) still remains to be a challenge . The program of safety re-evaluation of TCM injections provides an opportunity to practice QbD approach in TCM industry . This paper discussed some potential ways that improve the quality of TCM injec-tions base on QbD related tools , including identification of critical quality attributes , critical process parameters and critical material attributes, development of design space and control strategy.

Objective To investigate the value of cluster cate forpatients with ventilator-associated pneumo-nia (VAP) in the intensive care unit. Method Three hundred fifty-four consecutive patients with mechanical ven-tilation support in the Emergency Intensive Care Unit of Nanjing First Hospital from January 2006 to September 2007 were included in this study. The cluster care included elevating patient's head and chest to at least 30 de-grecs to the horizontal level, intensiving frequency of oral-pharyngeal nursing with thorough suction, washing hands, changing ventialtor tube at shorter regular interval, closely observing temperature, sputmn, WBC count, pu-turn, white blood cell count, chest X-ray examination and respiratory tract bacterial culture etc. Another 398 me-chanical ventilated patients with conventional care in the Hospital from January 2004 to November 2005 were taken as control. The t -test and X2 -test were used for analysis. Results The morbidity of VAP was significantly de-creased after cluster care(16.6 % vs. 24.6% P<0.01), the length of intensive care unit stay (LOS) was shorter in patients with cluster care than those in patients of control [(10.75±5.86) d vs. (14.26±9.40) d, P <0.05]. Conclusions Pneumonia associated with mechanical ventilation can be effectively reduced by the cluster care.

Objective To evaluate the applicated value of color Doppler ultrasonography (CDUS) and CR molybdenum target in the diagnosis of breast nodules.Methods Comparative analysis of 87 patients with breast nodules diagnosed by CDUS and CR molybdenum target were contrasted with postoperative pathology.Results 47 cases of 78 patients with breast nodules were benign lesions.39 cases were correctly diagnosed by CR molybdenum target,41 cases were correctly diagnosed by CDUS,and 44 cases were correctly diagnosed by CR molybdenum target and CDUS.Contrasted with postoperative pathology,the accuracy rates of breast disease diagnosed were 82.5％,75.0％ and 95.0％ diagnosed by CR molybdenum target,CDUS,CR molybdenum target and CDUS.Conclusion There is no significant statistical difference between CR molybdenum target and CDUS in the diagnosis of benign breast nodules.The accuracy rate of breast disease diagnosed by CR molybdenum target and CDUS is better than that diagnosed by CR molybdenum target or CDUS only.The two co-diagnosis are benefit to raise the accuracy rate of breast nodules.

OBJECTIVE To quantify the HBV DNA in saliva of chronic hepatitis B(CHB) patients and to study its relation to the periodontal status of the patients. METHODS HBV DNA were isolated from 60 patients with CHB by Trizol-chloroform method.HBV DNA levels were tested by real-time PCR technique and their relationship with plaque index,gingival index and probing depth was analyzed. RESULTS The positive rate of HBV DNA was (56.7%,) and the level of HBV DNA was 4.16+0.57(LogE,copies/ml) in saliva.The detectability of HBV DNA in saliva had no significant correlation with the values of oral clinical parameters. CONCLUSIONS The detectability and level of HBV DNA in saliva have no correlation with the oral hygienic parameters.Other sources of the HBV DNA may exist besides the serum in saliva.

Objective To observe the effect of miR-132 transfection on proliferation and apoptosis of pancreatic cancer SW1990,and to explore the underlying mechanism.Methods The expression of miR-132 in the pancreatic cancer tissue and the adjacent tissues in 28 pancreatic cancer patients were detected by realtime quantitative polymerase chain reaction (RT-qPCR).miR-132 was transfected into SW1990 cells by using liposome method,untransfected cells and cells with missense miR-132 transfection were used as black control and negative control.The proliferation and apoptosis was detected by CCK-8 assay and DAPI staining.The transfected cells were implanted in nude mice as xenograft tumor,and TUNEL was used to detect the apoptosis; immunohistochemistry was used to detect the expression of Ki-67 and mucin-4 protein in the xenograft tumors and mucin-4,HER-2,p-FAK protein in transfected cells.Results The expression levels of miR-132 in pancreatic cancer tissue and adjacent tissues were 0.46 ± 0.11 and 1.24 ± 0.36,and the difference between the two groups was statistically significant (P ＜ 0.05).The expression level of miR-132 in transfected SW1990 cells was 2.95 ± 0.46,which were significantly higher than those in negative control (0.84 ± 0.17) ; the survival rate of transfected cells at 48,72,96 h was 56.5％,44.7％,37.4％ of negative control cells.The apoptosis rate in transfected cells was 41.6％,and the corresponding value was 5.7％ in negative control,and the difference was statistically significant (P ＜ 0.05).The expression levels of mucin-4,HER-2,p-FAK in nagative control were 2.94 ± 0.42,1.75 ± 0.37 and 2.74 ± 0.24,and the corresponding values in transfected cells were 0.76 ± 0.14,0.34 ± 0.04 and 0.27 ± 0.03,and the difference between the two groups was statistically significant (P ＜0.05).In vivo,the growth of xenograft tumors in transfected nude mice was significantly inhibited [(0.23 ± 0.05) vs (0.59 ± 0.13) g,P ＜ 0.05],the apoptosis of xenograft tumor cells was significant increased [(21.7 ± 4.7) ％ vs (5.2 ± 0.7) ％,P ＜0.05].The expressions of mucin-4 and Ki-67 protein in nagative control was 281.34 ± 36.62 and 148.05 ± 21.34,and the corresponding values in transfection group were 64.35 ± 7.16 and 30.75 ± 4.61,and the difference was statistically significant (P ＜0.05).Conclusions miR-132 transfection has an effect of inhibiting proliferation and promoting apoptosis on SW1990 cells,and the mechanism may be down-regulation of mucin-4,HER-2,p-FAK protein rxpression.

Objective To discuss the techniques and indications of retroperitoneal laparoscopic nephrectomy. Methods Retroperitoneal laparoscopic nephrectomy was carried out in 21 cases from March to December in 2003, including 12 cases of renal calculus associated with severe hydronephrosis, 1 case of renal tuberculosis, 6 cases of renal carcinoma and 2 cases of renal pelvis carcinoma . Results All the operations were successfully completed and no serious complications were observed. The operation time was 2 hours ～ 3 5 hours (mean, 3 hours) and the blood loss was 10 ml ～ 300 ml (mean, 178 ml). Follow-up for 1 months ～ 9 months in 8 cases of renal carcinoma showed no recurrence or metastasis. Conclusions Retroperitoneal laparoscopic nephrectomy has advantages of minimal invasion, short hospital stay and rapid recovery, indicated for many kinds of benign or malignant renal diseases .

Objective To evaluate the safety、feasibility and the long-term effectiveness of polyurethane stent placement for treatment of nasolacrimal duct obstruction. Methods Fifty-three cases (64 eyes) with complete nasolacrimal duct obstruction received the lacrimal stent placement. Dacryocystography was performed before and after the procedure. The average follow-up period was 48.3 months (range, 13-78months), the long-term patency and the effectiveness after stents removal were analyzed. Results Stent placement was technically successful in 62eyes, and the success rate was 96.9% with no severe complications. On long-term follow up, the stent patency rate was 76.8% at 1 year. However, it decreased to 33.3% at 3 years and 28.6% at 5 years. Nine stents were removed when the symptoms recurred, including granulation tissue in 4 stents and mucous material in 5. After removal, 2 nasolacrimal ducts were patent, and 2 kept patent after stents replacement, but all reoccluded within 6 months. Conclusions Interventional placement of polyurethane stent in the obstructed nasolacrimal duct is a simple and safe outpatient procedure, but the long-term patency is not encouraging, and the right stent removal time has not yet been approved.
