Hydronephrosis is one of the most common urological diseases in children.Most of hydronephrosis caused by ureteropelvic junction obstruction.Whether these children need operations were being argued.The current tendency is when the renal function become worse,operation is suggested needed,in order to save the renal function.So the methods how to evaluate the renal function are especially important,this article related to the current research and review.

Objective To investigate the clinical therapeutic effects of neuromuscular electric stimulation (NMES) on patients with swallowing disorders after stroke. MethodsA total of 98 patients with a swallowing disorder after stroke were randomly divided into an NMES group (38 cases),a rehabilitation group (30 cases) and a control group (30 cases).In the control group the patients were treated with medication only; the in rehabilitation group they were treated with medication and swallowing rehabilitation training; in the NMES group they were treated with medication and NMES.The treatments lasted for 3 weeks in all groups.The swallowing function of patients in each group were observed and assessed with dysphagia scoring pre-and post-treatment.Complications of the swallowing disorders,side effects of treatment and the stomach tube leaving rate were observed. ResultsAfter treatment,the dysphagia scores of patients in the NMES and rehabilitation groups both increased,but the average scores in the NMES group were significantly higher than in the rehabilitation and control groups.The difference in therapeutic effect between the three groups was statistically significant.After treatment,the incidence of aspiration pneumonia in the NMES group was significantly lower than that in the control and rehabilitation groups.The average stomach tube leaving rate in the NMES group was significantly lower than that in the control group,but there was no significant difference in stomach tube leaving rates between the rehabilitation group and the NMES group.There was no significant difference among the three groups in malnutrition.No side effect was observed in any group.Conclusions NMES could alleviate post-stroke dysphagia and decrease the incidence of aspiration.The short-term therapeutic effect of NMES was better than that of swallowing rehabilitation training,but the long-term therapeutic effects were about the same in the two groups.

Objective To evaluate the effect of percutaneous coronary intervention(PCI) on myocardial perfusion in coronary heart.Methods Fourty-two patients with coronary heart disease who were confirmed to have coronary artery steonsis by the coronary angiography were selected.They were checked by myocardial contrast echocardiography of intravenous before and after treatment by PCI.Then we determined quantitatively the perfusion of coronary microcirculation based on the extent of myocardial imaging and recorded it images.The myocardial contrast echocardiography result was compared before and after treatment by PCI for evaluating the situation of myocardial perfusion and effect of PCL So we can estimte the patients' prognosis.Results There were 39 eases of 42 patients with PCI that their lesion vascular were all opening and unblocked.Repeated radiography showed that their TIMI blood flow was the third level.The partial cross sectional area of all the capillaries [A =15.46 ± 3.27) min] blood flow velocity [β =(0.75 ±0.16)min/s],and myocardial blood flow volume[A - β =(12.00 ±4.51 ) min2/s] dependent on myocardial segments all increased more significantly than those before the PCI[A =(6.68 ± 1.76) min,β =(0.40 ± 0.12) min/s、A · β =(2.82 ± 1.38 ) min2/s] (t =37.2527.58、30.65,P ＜ 0.05 ).After PCI three months the EF value of follow-up patients was increased mote than that of before PCI (t =13.77,P ＜ 0.01 )but the scoring index of ventricular wall motion was decreased more than that of before PCI ( t =8.75,P ＜ 0.01 ).Correlation analysis showed that after PCI A,β,A · β all had a strong correlation ( every P ＜ 0.01 ).Conclusion PCI could effectively improve the situation of myocardial perfusion in myocardial infarction patients.It could save ischemia myocardial in infarction field and also improve the function of left ventricular if patients implemented PCI operation as soon as possible.

Objective　To study the changes of quantitative expression,adhering activity and genomic density polymorphism of complement type 1 in erythrocytes (CR1) of patients with liver cancer (104 patients) and their clinical significance.Methods　Polymerase chain reaction (PCR),HindIII restriction enzyme digestion,the quantitative assay of ECR1 and the adhering activity assay of CR1 in erythrocytes were used.Results　No difference was observed between the patients with liver cancer (29.8%) and healthy individuals (25.3%) in the spot mutation rate of CR1 density gene (χ2 =0.537,P>0.05).The number and the adhering activity of CR1 in patients with liver cancer (0.83±0.22 and 47.1±6.5) were significantly lower than those in healthy individuals (1.26±0.33 and 62.4±7.6; t=10.5,P<0.0001).The number and the adhering activity of ECR1 in high expression genomic type (HH) liver cancer were obviously lower than those of healthy individuals,expecially those of the patients with advanced liver cancer.There was a good relationship between quantitative expression,adhering activity of ECR1 and liver cancer development.Conclusion　Defective expression of CR1 in liver cancer is mostly acquired through central peripheral mechanisms.The changes of CR1 quantitative expression and adhering activity are consanguineously related to the severity and the activity of the development in patients with liver cancer.

The publication of research papers is an important mark of achievements in scientific research. It is an index for checking the completion of various projects as well as a form of project completion. In order to better fulfill the tasks in scientific research, to enable more research projects to become bid winners, to turn out more quality papers, to produce outstanding results, and to further strengthen management and supervision of scientific research, the hospital the authors work with formulated at the end of 1999 "quantitative economic management of research quotas", which was put into effect at the beginning of 2000. An effect analysis of the implementation of the measure in the past three years showed that the desired results were basically achieved, academic advancement and personnel growth were greatly promoted, and the publication of research papers became a key index for evaluating the timely completion of research projects. In future the hospital plans to further improve the policy for rewarding writers of research papers and encourage quality academic papers to be published in key international journals.

Objective To understand the trends of institutional delivery in recent 30 years in China and find out the main social and demographic factors. Methods Two-staged PPS method was employed for sampling; Uniform questionnaire was drafted and direct interview was adopted to collect the information. Results The institutional delivery rate was increasing rapidly with time, especially from 1990's, which had climbed to 82% in the last three years, but it was still unsatisfactory in the central and western areas. Meanwhile, most women who delivered outside the hospital were assisted only by birth attendants/village doctors or family members/friends in labor. Factor analysis showed that the women s education and occupation and their husbands, the gap of education between the couples, and the antenatal care could significantly affect their choice for where to deliver. Conclusions Great improvement had been achieved in the last several decades, and both individual characteristics, community and health facility could have influences on the women s decision on where to give birth.

Objective To investigate the feasibility,reliability,and complications of laparoscopic second-look exploration for ovary epithelial cancer.Methods The operation was performed under general anaesthesia.The 4-port laparoscopy was carried out.Physiological saline was used to wash the abdominal and pelvic cavity for cytological examination.Then the exploration of abdominal and pelvic cavity was performed,adhesions were dissected,and multiple punch biopsies(at more than 20 sites) were conducted in the abdominal and pelvic cavity.Results All the operations were completed successfully.The operative time was 61.3?16.7 min,and the hemorrhage volume was 98.7?32.1 ml.Positive findings were encountered in 4 cases(28.6%),3 of which(21.4%) were identified by the naked eye and 1 of which was identified by microscope,and negative findings,10 cases(71.4%).Of the 4 cases of positive findings,the tumor was located at the pelvic peritoneum or the paracolic sulci peritoneum.No abdominal organ injuries occurred,and no conversion to open surgery was needed.Delayed healing of umbilical incision happened in 1 case.Of the 10 cases of negative findings,recurrence of tumor was observed in 1 case(10.0%) at 48 months after operation.Conclusions Laparoscopic second-look exploration for ovary epithelial cancer is feasible,with advantages of minimal invasion,fast recovery,and good patient's tolerance.

Objective To investigate the feasibility of laparoscopic radical hysterectomy and abdominopelvic lymphadenectomy in the treatment of malignant uterine tumors.Methods Laparoscopic radical hysterectomy and abdominopelvic lymphadenectomy was performed in 62 cases of biopsy-confirmed early-stage malignant uterine tumors from February 2003 to August 2005.There were 26 cases of endometrial cancer and 36 cases of cervical cancer.Pelvic lymphadenectomy was conducted in all the cases;while selective lymphadenectomy of peripheral lymph nodes of the abdominal aorta was performed in 5 cases,followed by laparoscope-assisted vaginal hysterectomy(LAVH).Results The operation was completed under laparoscope in 61 cases,and a conversion to open surgery because of venous injuries was encountered in 1 case.The operation time was 165～265 min(mean,217 min);the intraoperative hemorrhage volume was 150～1200 ml(mean,260 ml);the number of excised lymph nodes was 13～23(mean,17).Bladder injury happened in 1 case and was successfully repaired under laparoscope.Postoperatively,urine retention developed in 4 cases and lymphatic cyst occurred in 5.Follow-up checkups for 1~28 months in 61 cases showed 1 case of recurrence at 3 postoperative month(stage Ⅱ_B cervical adeno-squamous carcinoma,withdrew from the treatment and died 4 months later).Conclusions Laparoscopic radical hysterectomy and abdominopelvic lymphadenectomy is safe,feasible,effective,and reliable.
