Ningbo City has established a third-party mediation mechanism for medical disputes,attempting to resolve medical disputes by a third party independent of doctors and patients in a fair manner.Such a third party refers to the people's mediation committees for medical disputes and medical disputes compensation centers at various levels.This mechanism features advantages more than one,and has its challenges to address as well.Tasks to perform include study of the existing laws and regulations on compensation,appropriate increase of present compensation level for medical damages,improvement of the medical responsibility insurance mechanism,clarification of the nature of the people's mediation committee,and promotions for an ideal social environment.

Objective To observe the effect of Shenmai injection on congestive heart failure(CHF) and the effect on thyroid hormone as well as medicine security. Methods 52 patieits with CHF were enrolled,Shenmai injection was used with regular western medicine in the treatment. And observed its effect and test serum thyroid hormone: TSH,T3 ,T4 ,rT3. Another 50 CHF patients were enrolled as a control. Results The results of observation were that 25 cases were very effective,23 were effective,4 had no effect and the total effective rate was 92%. The results of control group were that 21 were very effective, 16 were effective, 13 had no effect and the total effective rate was 74%. The differences between the two groups were significant (P > 0.05). By comparing two thyroid hormone T3, T4, rT3, the observation T3 and T4 was obviously higher than the control. rT3 was lower than the control. Conclusion Shenmai injection could efficiently improve the heart function of CHF,cure arrhythmin and correct the illness caused by thyroid hormone.

Marine microorganisms,which live in special biotic environment,have been proven to be potential in producing novel bioactive substances.In past three decades,nearly 300 new compounds have been isolated and determined from marine fungi,and most of them showed antitumor,antibacterial and antiviral activities.This paper reviewed new advances in the studies of antitumor compounds from marine fungi in the recent ten years.

Objective To study the feasibility and safety of hand-assisted laparoscopic hepatectomy combined with splenectomy. Methods Hand-assisted laparoscopic hepatectomy combined with splenectomy was performed in 3 patients. A midline epigastric or right subcostal incision was made for hand-assisted port. The attachments of the spleen were dissected with a harmonic scalpel and the pedicle of the spleen was severed with the Endo-GIA. The transection of the liver was conducted using the harmonic scalpel dissection and nonabsorbable polymer clipping. The cut surface of the liver was closed by interrupted sutures. Results The operation was successfully completed in all the 3 patients. The surgical time was 130 min, 115 min, and 145 min, and the blood loss was 350 ml, 50 ml, and 150 ml, respectively. No serious postoperative complications occurred. The postoperative hospital stay was 9, 7, and 11 days, respectively. Follow-up observations for 6, 23, and 5 months showed no recurrence. Conclusions Hand-assisted laparoscopic hepatectomy combined with splenectomy is feasible and safe in selected patients .

Objective To discuss the relationship between IL-13R?2 and the tumorigenesis and progression of gliomas. Methods Expression level of IL-13R?2 mRNA was studied by Reverse Transcription-Polymerase Chain Reaction(RT-PCR) in 20 cases of glioma and 5 cases of normal brain tissue. Results There was no expression of IL-13R?2 mRNA in all cases of normal brain tissue, wherea 13 of 20 gliomas expressed IL-13R?2.There were specially significant difference between them(P0.05) between low grade gliomas and high grade gliomas, there was greatly significant difference(P

Objective: To investigate the protective influence and mechanism of Yishen Huayu Formula on the expression of connective tissue growth factor (CTGF)in the rat with renal interstitial fibrosis. Methods: 150 rats were randomly divided into sham-opration group, model group, Lotensin treatment group, Yishen Huayu high low dose treatment groups. The rat models with renal interstitial fibrosis were induced by unilateral ureteral obstruction. The expressions of CTGF in the kidneys were observed on 3rd, 7th, 14th, 21st, 28th day. The alterations of renal the expressions of CTGF in the kidneys were observed with the ?-actin as intrinsic control. Results: Compared with the control group,the expression of CTGF increased signifi cantly in model group(P

With the development of technology and economy, the whole living space has been filled with different vibration, the chance of exposure to vibration for people is on the increase. Environmental vibration is one of seven main pollutions in the world, people’s health is threatened. The main four factors effected human body vibration were introduced in this paper, and the adverse effects on the systems were discussed, the criterion of evaluating human response to vibration based on international and national standards were analyzed.

Background and purpose:Several reports demonstrated that the expression of STAT3 has been found to be an oncogene in solid tumors such as head and neck squamous cell carcinoma,esophageal carcinoma and prostate carcinoma.This study was done to explore the effects of X-ray irradiation combined with RNAi against STAT3 on proliferation and apoptosis of human esophageal carcinoma cell line Eca-109.Methods:Three pairs of DNA template coding siRNA were synthesized against STAT3 to reconstruct pRNAT-U6.1-siRNA-STAT3,which was transfected into Eca-109 cells,the positive cell clones were screened with G418.Inhibitory effect of STAT3 mRNA and protein in Eca-109 cells was detected by RT-PCR and Western blot,respectively.The transfected cells were exposed to 0,2,4,6 and 8 Gy X-ray respectively;the survival fraction of Eca-109 cells was analyzed by clone formation assay,and flow cytometry was applied to analyze cell apoptosis at the dose of 4 Gy.Results:pRNAT-U6.1-siRNA-STAT3 was reconstructed and identifi ed as correct by sequencing.RT-PCR and Western blot analyses demonstrated that STAT3-siRNA could obviously reduce the expression of STAT3 mRNA and protein in Eca-109 cells.Clone formation assay and flow cytometry results showed that irradiation at different doses combined with STAT3-siRNA could inhibit the proliferation of Eca-109 cells,irradiation with 4 Gy X-ray could induce apoptosis.Conclusion:X-ray irradiation combined with RNAi against STAT3 could inhibit the proliferation of Eca-109 cells and induce apoptosis.

Gene transfection is an important method for studying gene function. The origination and development of gene transfection are reviewed in this article. Six methods of gene transfection are introduced, among which, special attention are given to two new ones: particle bombardment and photochemistry transfection technology. Besides, the advantages and disadvantages of these methods are compared in order that more suitable methods can be chosen in researches. The application of the technology in gene research is discussed in the end of this article.

Objective To evaluate the treatment effect of PFNA clinical analysis in patients with intertro-chanteric fracture application.Methods 40 cases of intertrochanteric fractures PFNA internal fixation treatment were selected,the operation time,intraoperative blood loss and fractures healing time,degree of hip joint function recovery after operation and the postoperative complications were observed.Results Operating time was 60 -120minutes,with an average of (90.0 ±12.5)minutes.Intraoperative blood loss volume was 200 -600mL,and the average volume was 380.8 plus or minus 58 ml.Fracture clinical healing time was 8 to 15 weeks,with an average of (10.5 ±2.5)weeks. According to Harris hip joint function score,the overall good rate was 85.5%.There were no postoperative complica-tions occurred.Conclusion PFNA applies to all types of intertrochanteric fractures,especially for the old type osteo-porosis bone fracture,which with simple operation,small trauma,fixed firmly,fracture healing fast and less complica-tions.It is worthy of clinical use.
