Objective To evaluate the advantages and disadvantages between transabdominal myomectomy(TAM)and laparoscopic myomectomy(LM).Methods We were trospectively reviewed the clinical data of 35 cases of TAM and 30 cases of LM,analyzed adaptation,complication,bleeding quantity and recover time.Results Every patients operated successful.The operation time of LM group was longer than TAM group.The bleeding quantity,recovery time and post-operation in-hospital days of LM group were all shorter than TAM group.Conclusions Laparoscopic myomectomy have advantages of micro invasion,rapidrecovery,less in-hospital days and less complication.

Objective To analyse the dianosis and treatment process in suspicious ectopic pregnancy(67 cases)and explore the value of diagnostic curettage in suspicious ectopic pregnancy.Methods Elect ectopic pregnancy cases in conservative treatment(67cases),divide these cases in two group as the diagnostic curettage group and the control group in random and analysis their success ratio in conservative treatment;time in hospital;expense in treatment.Results The success ratio in conservative treatment were similar in two group ;the time in hospital and expense in treatment was significant lower in diagnostic curettage group.Conclusions Diagnostic curettage was useful in differential diagnosis of suspicious ectopic pregnancy;It can reduce the time in hospital and the expense in treatment.

OBJECTIVETo evaluate the clinical effects of short-segment transpedicular fixation and vertebroplasty via paraspinal intermuscular approach in treating thoracolumbar fractures.

METHODSFrom January 2009 to January 2012,18 patients with thoracolumbar fractures without neurological symptoms were treated with short-segment transpedicular fixation and vertebroplasty via paraspinal intermuscular approach. There were 11 males and 7 females, aged from 52 to 76 years old with an average of 62.2 years. The duration from injuries to surgery ranged from 8 h to 7 d with an average of 4.2 d. According to the Denis fracture classification, 12 cases got compression fractures and 6 cases got burst fractures.

LOCATION6 vertebra with T12, 9 with L1, 6 with L2, and 3 with L3. Anterior vertebral body height, the sagittal Cobb angle, the sagittal index (SI), condition of internal fixation failure and recurrent kyphosis were observed.

RESULTSAll patients were followed up for 12-28 months with an average of 16.5 months. Operation time was from 80 to 130 min with a mean of 95 min and bleeding volume during operation ranged from 100 to 180 ml with a mean of 145 ml. Anterior vertebral body height ratios preoperation, 3 days after operation and final follow-up was 54.3 +/- 2.8, 90.9 +/- 1.5, 88.6 +/- 1.7, respectively; sagittal Cobb angle was (27.8 +/- 2.5) degrees, (5.3 +/- 0.8) degrees, (6.3 +/- 1.4) degrees, respectively; sagittal index was 52.3 +/- 3.8, 89.2 +/- 5.2, 86.4 +/- 4.5, respectively. Data obtained 3 days after operation obviously improved than preoperation, and there was no statistically significant difference between 3 days after operation and last follow-up. No internal fixation failure, neurological complications and recurrent kyphosis were found.

CONCLUSIONTreatment of thoracolumbar fractures with short-segment transpediclar screw fixation and vertebroplasty via paraspinal intermuscular approach can retain the posterior ligament complex and restore the mechanical strength of the anterocentral column,which proved an ideal method for preventing the failure of internal fixation and reduction of post-traumatic segmental kyphosis.

AIM:To understand the interaction between a195- kilodalton protein,P195, on the surface of Plasmodium falciparum merozoite and human erythrocyte.METHODS:P195 was expressed in eight fragments in E.coli.After being refolded,the expressed proteins were la- belled with12 5 I,and incubated with human erythrocytes.RESULTS:According to binding assay, three fragments of P195:M3,M6,M9were found to have ability to bind to human erythrocyte. M6,which is equal to amino acid( AA) sequence from384 to595,could bind to human erythro- cytes but not to trypsin treated human erythrocytes,and the binding could be eluted by low p H buffer solution. M3( AA 12 3to 30 2 ) and M9( AA 10 78to 12 51) also have the ability to bind to human erythrocytes,but the binding was not affected by trypsin treatment and low p H buffer elu- tion. CONCL USION:The binding site of M6might be a surface protein receptor of human ery- throcytes,while the binding site of M3and M9might be an intracellular componentof human ery- throcyte.

Objective To study the ulnar nerve and its adjacent structures in the forearm and understand the anatomic basis for endoscopic harvesting of the ulnar nerve for the treatment of brachial plexus avulsion injury. Methods Ulnar nerves and their adjacent structures in 6 formaldehyde solution fixed upper limb specimen and 26 fresh upper limb specimens were carefully dissected and observed and measured. The entry path and implementation were designed according to the observations. Simulated operation was performed in 6 fresh autopsy specimens Results In the forearm, ulnar nerve passes through the flexor carpi ulnaris under the medial epicondyle of the humerus and the dorsal branch of the hand passes between the ulnar bone and flexor carpi ulnaris. Also the ulnar nerve descends through intermuscular space, accompaning the ulnar artery in the distant part of the forearm and the artery lies laterally along the nerve. The simulated operations were successfully done in all the 6 specimens. Conclusions The anatomy of the ulnar nerve in the forearm is fairly fixed with no crossing with important structures in its path, incisions of 1～2cm are made above the pisiform bone and under the medial epicondyle of the humerus 3～5cm respecitvely, After isolation of the ulnar nerve's two crosses from the muscle, the remaining part of the ulnar nerve and its adjacent structures are easily dissected. It is concluded that it is safe and reliable to harvest the ulnar nerve in the forearm with endoscopy.

Objective To evaluate the efficacy of ureteroscopic pneumatic lithotripsy in the treatment of ureter stones.Methods A total of 186 cases ureteroscopic pneumatic lithotripsy were performed in our hospital.The outcomes of the surgery were analyzed.Results The success rate of the operation was 80.6%(29/36) for the upper ureteral calculi,92.7%(51/55) for the middle,and 100%(95/95) for the lower ones,respectively.Four weeks after the surgery,re-examination showed that the rate of stone removal was 94.1%(175/186).Injuries to the ureter occurred in 5(2.7%) of the cases.Conclusion Ureteroscopic pneumatic lithotripsy is an effective and safe method for ureteral calculi.

Objective To investigate the effect of ?-blockers on spatial dispersion of ventricular repolarization following acute myocardial ischemia.Methods Twenty sheep were randomized into control(normal saline i.v.)and atenolol group.Acute myocardial ischemia was induced by occlusion of the obtuse marginal coronary artery.Unipolar ECG was simultaneously acquired from 64 epicardial sites in both ischemic and non-ischemic regions.Activation-recovery intervals(ARI)were determined from the epicardial ECGs.The difference between the longest and shortest ARI was defined as ARI dispersion.Results Ischemic zone in the atenolol group was less than that of the control group[(13?2)% vs (19?3)%,P

AIM: To investigate the relationship between somatostatin and the pathologic type, estrogen receptor,DNA ploidy of nuclei in tumor cells of breast cancer.METHODS: 67 cases of primary breast cancer and 25 cases of benign breast tumor were examined by immunohistochemical stretomyces avidin peroxidase method. 26 cases of breast cancer selected at random were analyzed by flow cytometry.RESULTS: Somatostatin expressed significantly higher in low malignant breast cancer than that in high malignant breast cancer ( P

Objective To explore the necessity and models of developing community health services in rural areas. Methods Both quantitative and qualitative studies were conducted. Results Those who regarded developing community health services in rural areas as highly necessary accounted for 35% while those who regarded it as necessary accounted for 58% . The model of cooperation between township and village or between hospital and village was advocated for areas with an average income of 1 000 yuan and above; the model of combining the hospital with the health station or three "five in ones" was advocated for areas with an average income of 2 000 yuan and above; and the model of "three in one" was advocated for areas with an average income of 3 000 yuan and above. Conchusion There are many factors that influence the development of community health services in rural areas, but the models selected vary mainly because of the difference in income levels and the difference between various areas.
