Ptosis is one of the most common diseases in oculoplastics. Surgical treatment is the only way to correcting ptosis. Most of doctors paid special attention to surgical technique, rather than to some related issues of operation. Timing is crucial for ptosis surgery. Both cosmetic and function need to be considered for a success surgery, the evaluation of extraocular muscle disorder is impor- tant for surgical result and postoperative complications.

Objective To compare efficacy and side effects of intravenous versus oral indomethacin treatment for symptomatic patent ductus arteriosus (PDA) in preterm infants.Methods Fourty-nine preterm infants were reviewed retrospectively who were diagnosed as having symptomatic PDA confirmed by echocardiography.According to the using type and approach that were divided into 2 groups (intravenous group,n=21;oral group,n=28) and their doses and intervals were same.The rates of ductal closure and side effects were compared in 2 groups.Results There were no significantly different between 2 groups in single ductal closure and complicating other diseases. Soon closure of intravenous group was higher significantly than oral group [61.9 %(13/21) vs 28.6 %(8/28),P

Objective:To investigate the value of magnetic resonance cholangiopancreatography(MRCP)in the diagnosis of pancreas divisum by comparing with endoscopic retrograde cholangiopancreatography(ERCP).Methods:The MRCP and ERCP images of 8 patients with pancreas divisum were retrospectively analyzed.The diagnostic accuracy and findings by MRCP were compared with those by ERCP.Results:MRCP had a diagnostic accuracy of 87.5%(7/8)based on the result of ERCP.ERCP displayed the dominant dorsal pancreatic ducts in all 8 cases and ventral pancreatic ducts in 6 cases;MRCP also displayed the dominant dorsal pancreatic ducts in all 8 cases,but the ventral pancreatic ducts only in 3 cases.Conclusion:As a non-invasive technique,MRCP has important clinical value in the diagnosis of pancreas divisum.

Xenotransplantation is a feasibility way of solving the shortage of human organs for transplantation. Although it is urgently needed to satisfy the demand of people and sustain the function of human organs, there are multiple hurdles existed to clinical application, such as the immune rejection between human body and the xenografts, the infection of pathogens and a series of ethic, morality and social issues. A historical retrospect of xenotransplantation was given, and then probe into the strategies according to the main problems and the actualities. Finally, the prospect in the field of xenotransplantation was showed.

Viable but non-culturable state in bacterial cells as received uncultured microorganism has be- come the fundamental research issues in medical microbiology, epidemiology, general microbial ecology and sanitation quarantine since it was put forward in 1982. When in this state, bacterium are no longer able to grow and form colonies on conventional culture media, but maintain their patheogenicity, may become latent infection escaping detection to threaten enviroment and human security. With the development of modern molecular biology technique and metagenomics, it provide new research method and opportunity for uncul- tured microorganism in the environment. Recently, with the application of the metagenome technique, ge- netic fingerprinting technical etc, it becomes more and more popular. Simultaneously, along with this state become maturity in the laboratory. It provides a new research route for development and exploitation the uncultured microorganism.

There have been very few studies on the effect of Gualou Xiebai Banxia decoction combined with Xuefu Zhuyu decoction in inhibiting apoptosis in myocardial ischemial injury caused by coronary heart disease. In this experiment, Gualou Xiebai Banxia decoction combined with-Xuefu Zhuyu decoction were used to intervene the miniature swine phlegm and blood stasis type coronary heart disease model, in order to observe the effect of the combined prescription on the myocardial apoptosis and the expressions of Bcl-2, Bax, Caspase-3, Caspase-9 in the model. Totally 15 Chinese experimental miniature swine were adopted and randomly divided into the control group, the model group and the phlegm and stasis-treating group. The model group and the stasis-treating group were fed with high fat diets for two weeks, intervened with the coronary artery injury and then given drugs and high fat diets for eight weeks. The control group was fed with ordinary diets for 10 weeks, without the coronary artery injury. After the experiment, myocardia at the juncture of infracted areas were collected and made into formalin-fixed paraffin sections. The TDT-mediate dUTP nick end labeling (TUNEL) assay was used to detect the myocardial apoptosis. The immunohistochemistry (IHC) technique was applied to detect Bcl-2, Bax, Caspase-3, Caspase-9 levels in myocardial tissues. According to the findings, the apoptosis indexes (AI) for the control group, the model group and the phlegm and stasis-treating group were 0.92%, 27.68%, 17.28%, respectively. The AI of the phlegm and stasis-treating group was significantly lower than that of the model group (P < 0.01). Compared with the model group, the phlegm and stasis-treating group showed significantly higher Bcl-2 protein expression (P < 0.01) and lower Bax, Caspase-3 and Caspase-9 protein expressions (P < 0.01). In conclusion, Gualou Xiebai Banxia decoction combined with Xuefu Zhuyu decoction have a significant protective effect against the myocardial apoptosis in miniature swine phlegm and blood stasis type coronary heart disease model.

Objective To validate a new standardized training program for urological surgeons to improve their laparoscopic surgical skills. Methods The laparoscopic surgical training program was carried out by using the traditional mechanical simulators and animal models. Thirty-three trainees participated the urological laparoscopic surgical training program. Initially, the novices were assigned to practise basic laparoscopic skills step by step on the simulator with fixed trocar positions. After a period of basic training, they were allowed to practise on animal models for some particular proce-dures. Results All trainees (33/33, 100.0%) participated were able to perform all basic techniques skillfully and completed laparoscopic anastomosis accurately after the training. The time required for performing the partial nephrectomy, dismembered pyeloplasty and ureteral reimplantation on animal models declined from 64.0±18.4, 127.54±17.5 and 75.84±11.6 min at the beginning to 30.94±3.8, 65.2±7. 5 and 37.7±7.2 min after practicing these procedures 8 times (P<0.01). They could un-derstand the crucial procedures of the laparoseopic surgeries after 6 to 8 special trainings on animal models. Fifteen trainees (15/33, 45.5%) had started to carry out laparoscopic surgeries after-finish- ing the training program. Conclusions Our program enables the participants to improve their techniques in complicated laparoscopic surgeries. The challenging parts of reconstructive laparoscopic surgeries such as laparoscopic dismembered pyeloplasty can be taught by using animal models. This program could be incorpo-rated easily by all urological departments developing a laparoscopie surgical training program.

In the present paper, we measured DNA content of uninuclear Plasrnodium berghei traced with DAPI by means of fluoromi-crospectrophotmeter. The results indicate that the DNA replication of parasite was continuous and it's content was high polyploidy and phase G1 of proliferating cycle was not evident. The dispersion degree of distribution of DNA content in P. R. was markedly lower and the peak sitewas more concentrated and obviously shifted to the right compared with P. N. It was suggested that the speed of DNA replication and proliferating vitality of parasites after producing resistance to SA markedly decreased, indicating that the changes of proliferating kinetics of P. R. happened.

Objective To explore the factors of high level of serum estradiol(E2)in infant with hemangiomas and its relationship with tumors' proliferation.Methods The levels of serumal estradiol of 25 proliferative hemangiomas and 15 oblique inguinal hernias with same ages 1 day preoperation and 3 days postoperation were tested by chemiluminescence enzymatic immune method.The expressions of estrogen receptors(ER)in 25 tumors and 15 normal skin tissue were tested by immunohistochemical method.Results The levels of E2 of preoperation were ob-viously higher than that of postoperation in hemangiomas and control group(Pa0.05).The expression of ER in tumors was significantly higher than that in normal skin tissue(P
