Journal of Medical Postgraduates 2003;0(12):-
Through G protein coupling and intracellular signal transmission, opioid peptides and its receptors in myocardial tissues participate in IPC have the function of early and delayed protection. The molecular mechanism of ”trigger-regulatory medium-effector” is of great significance in the study of the pathogenesis of IPC, as well as exploring the new idea for CHD prevention and cure.

Journal of Medical Postgraduates 2005;0(S1):-
Objective:To assess the therapeutic effects and adverse reactions of MS Contin in the treatment of acute myocardial infarction (AMI). Methods: 42 AMI patients were divided into experiment group and control group. Experiment group were given oral administration of MS Contin for 1 week besides the routine treatment of AMI for patients in the control group. Results: Between the two groups, the differences in the product of heart rate and blood pressure ( HR?BP) , the frequency of angina pecto-ris attack, the recovery time of the ST segment and the incidence of acute arrhythmia were significant. The most common side effects observed were: vomiting, constipation, hallucination, and the most severe toxic side effect was respiratory inhibition. Conclusion : In the treatment of AMI, MS Contin could relieve the pain effectively, reduce the incidence of angina pectoris attack and severe arrhythmia, decrease myocardial oxygen consumption, have tolerable side effects in the majority of patients. It is preferable to use MS Contin as a concurrent treatment of AMI.

Objective:To investigate plasma contents of ?-endorphin(?-EP) in patients with coronary heart disease(CHD) and study the relationship between myocardial function and ?-EP in these patients.Methods:At 12,24,48,and 96 h and 7 d after episode,the plasma levels of ?-EP were measured by immunoradiometric assay(IRMA).The left ventricular ejection fraction(LVEF) was measured with echocardiography and the class of cardiac function was assessed according to NYHA. Results:The plasma levels of ?-EP in 58 patients with CHD were higher than those in 20 healthy subjects(P

Three cases of renal pelvic neoplasm associated with staghorn calculi were enrolled to the study from March 2015 to June 2019. All patients underwent minimally invasive procedures previously including extracorporeal shock wave lithotripsy (ESWL), flexible ureteroscopic lithotripsy(FURL), or percutaneous nephrolithotripsy (PCNL). 3 patients of renal pelvic neoplasm with giant staghorn calculus were diagnosed by resection biopsy during laparoscopic pyelolithotomy intraoperatively and then treated by laparoscopic radical nephroureterectomy (LRNU). Case 1 was identified retroperitoneal lymph node metastasis 16 months after operation. Case 2 and 3 remained disease free. The timely diagnosis of renal pelvic neoplasm associated with staghorn calculi is always difficult, nevertheless, the laparoscopic pyelolithotomy with resection biopsy intraoperatively can be more effective in selected cases compared with routine endoscopic biopsy.

BACKGROUND: Human umbilical cord blood stem cells have been widely used in the study of spinal cord injury, but in vitro differentiation of human umbilical cord blood stem cells (hUCBSCs) has been limited by various factors. Mongalian medicine axillary choerospondias fruit extract has protective effects on neural cells, but the action mechanisms are unclear. OBJECTIVE: To observe promoting effects of 3 kinds of Mongalian medicine axillary choerospondias fruit extracts on in vitro differentiation of hUCBSCs. METHODS: Fresh umbilical cord blood was obtained from healthy puerperants to prepare hUCBSC suspension. The purified hUCBSCs were incubated in 40 petri dishes. The Mongalian medicine axillary choerospondias fruit extracts were divided into: sample 1 group: ethanol extraction, ethyl acetate extraction, crude drug mass concentration was 8.25 g/mL; sample 2 group: ethanol extraction, NKA resin isolation, 10% ethanol eluting concentration, crude drug mass concentration was 1.72 g/mL; sample 3 group: ethanol extraction, NKA resin isolation, 70% ethanol eluting concentration, crude drug mass concentration was 2.41 g/mL; control group: incubation of 80% DMEM containing 20% calf serum. Effects of various mass concentrations of Mongalian medicine axillary choerospondias fruit extract on hUCBSCs proliferation were observed. Proportion in S phase was measured using flow cytometry at 24 and 72 hours. RESULTS AND CONCLUSION: The proliferation of hUCBSCs was not significant in the sample 3 group. At day 10, the proliferation was significantly greater in the sample 1 and 2 groups compared with the sample 3 and control groups (P < 0.01). The number of hUCBSCs was significantly increased at 24 and 72 hours in S phase in the sample 1 and 2 groups. Mongalian medicine axillary choerospondias fruit extract (crude drug mass concentration 8.25, 1.72 g/mL) could promote in vitro proliferation of hUCBSCs.

Objective To evalute the indication and clinical application value of microwave abla-tion in spleen-preserving surgery in treament of patients with traumatic rupture.Methods The clinical data of 45 patients with traumatic splenic rupture were retrospectively analyzed.Spleen preserving surgery was feasible by preoperative CT evaluation and intraoperative observation.36 patients received simply mi-crowave ablation,and 9 cases received microwave ablation assisted partial splenectomy.Postoperative com-plications were observed,and the changes of platelet in peripheral blood were detected before and after op-eration in the 3 th,7th,14th day to evaluate the function of spleen.Results 15 patient was complicated with left pleural effusion,1 patient was complicated with splenic fossa fluid associated with infection.Dur-ing the follow-up of at least 2 months,No patients had postoperative bleeding,hemoglobinuria,gastrointes-tinal leak,deep vein thrombosis and pancreatic leak complications,no deaths.Seven days after microwave ablation spleen-preserving surgery,blood platelet count were significantly higher than the levels before the operation (P <0.05)in spleen-preserving patients.Platelets were no statistically significant after operation in the 3 th,14thday compared with the preoperative(P >0.05).The CT scan and the ultrasonic examina-tion that reviewed after operation in the 30-60th day showed good in spleen imaging in spleen-preserving patients,No patients had portal vein thrombosis.Conclusion Microwave ablation spleen-preserving sur-gery in the treatment of partial traumatic splenic rupture will be a safe and effective operation which could expand the spleen-preserving indication and be used in clinical practice.

Objective To investigate the feasibility and the short-term efficacy of laparoscopic surgery for the treatment of uterine malignant tumors. Methods Laparoscopic radical hysterectomy and pelvic lymphadenectomy was performed in 25 cases of cervical cancer and 24 cases of endometrial cancer from February 2003 to March 2005 in this hospital.Of the 49 cases,a selective paraaortic lymphadenectomy was carried out in 5 cases. Results All the operations were successfully performed under laparoscope except for 1 case of conversion to open surgery.The operating time was 190?45 min,the blood loss during operation was 172?99 ml,and the number of excised lymph nodes was 17?6.Surgical complications occurred in 8 cases(8/49,16%),including 1 case of bladder injury,1 case of internal iliac vein injury,3 cases of urinary retention,1 case of vesicovaginal fistula(VVF) at the 6 postoperative month,and 2 cases of lymphatic cyst.Follow-up observations were carried out for 1~12 months in 21 cases,12~24 months in 17 cases,and 24~27 months in 4 cases.No recurrence was seen.Conclusions Laparoscopic surgery for the treatment of uterine malignant tumors is safe and feasible and offers significant short-term effects.
