1.Comprehensive treatment for cervical carcinoma
Cancer Research and Clinic 2007;19(z1):146-147
Comprehensive treatment is the hot for cervical carcinoma,but comprehensive treatment is not the superposition of several treatment methods.Surgical treatment is the main means for early cervical carcinoma and radiotherapy for locally advanced. It's sure that radiotherapy combined with hyperthermia.Abroad,concurrent chemotherapy and radiotherapy is regarded as routine treatment methods.Improvement of hyperthermia technology is more applicated in the clinical.Reducing complications after treatment and enhancing the effectiveness of the treatment of cervical carcinoma is the ultimate goal.

Objective To find out whether the benefits entitled to peasants have increased since NRCM is in place in Beijing, and to analyze the extent of such benefit increase if any. Methods The first is to calculate changes to the reimbursement ratio of hospitalization charges for the peasants covered by NRCM; the second is to calculate the role played by NRCM for alleviating the catastrophic health expenditure of peasants. Results The reimbursement ratio of hospitalization charges for peasants covered by NRCM rose from 32.4% in 2004 to 45.4% in 2007. Survey data from districts and counties in the sampling test indicate that NRCM has gained an ever growing power in alleviating the catastrophic expenditure of peasants. Conclusion Recent years have witnessed a marked growth in medical charges, peasants' income, and peasants' demand for medical services. Against such a background, NRCM can still sharply downsize their catastrophic health expenditure, and its role keeps intensifying. This proves that the fund raising speed of NRCM has greatly outpaced the growth of medical charges and peasants' demand for medical services, and NRCM is playing a more effective role in alleviating the peasants from poverty caused by diseases.

BACKGROUND:It is shown in past researches that total saponin of ginseng has the effect of promoting multiplication of bone marrow hematopoietic stem cells and progenitor cells in vitro, and promoting secretion of bone marrow hemotopoietic factors, however there has been little researches on the effect of multiplication of bone marrow stromal cells.OBJECTIVE: To investigate the effect of ginsenoside Rg1 on pig's bone marrow stromal cells multiplication in vitro.DESIGN: A controlled observation.SETTING:Department of Cardiology and Department of Dermotology,First Affiliated Hospital, Nanjing Medical University; Department of Pharmacology, Nanjing Medical University.MATERIALS: The experiment was conducted at the Cardiovascular Pharmaceutical Laboratory of Nanjing Medical University from January 2002 to February 2003. The experimental pigs ahd the powder of ginsenoside Rg1were chosen METHODS :The bone marrow stromal cells cultured in vitro were divided as control and experimental groups. For experimental group insenoside Rg1 in different concentrations (10-7,5×10-7,10-6,5×104 mol/L)were added for induction culture, and for control group the media of the same volume was added. The multiplication conditions of bone marrow stromal cells were respectively detected by fibroblast colony forming in vitro, tritiated thymidine {[3H]TdR} incorporation and MTT.MAIN OUTCOME MEASURES: ① The effect of ginsenoside Rgl on the fibroblast colony forming units of bone marrow stromal cells in vitro. ②The effect of ginsenoside Rg1 on [3H]TdR incorporation of bone marrow stromal cells. ③ The effect of ginsenoside Rg1 on bone marrow stromal cells multiplication detected by MTT.RESULTS:① The effect of ginsenoside Rg1 on the fibroblast colony forming units of bone marrow stromal cells in vitro: The numbers of units in experimental group were all higher than that in control group (P < 0.05-P < 0.01),especially obvious in (5-50)×10-7 mol/L experimental group, reaching peak in the concentration being 10-6 mol/L. ② The effect of ginseno side Rg1 on [3H]TdR incorporation of bone marrow stromalcells: As the concentration of ginsenoside Rg1 was 10-6 mol/L, the [3H]TdR incorporation efficiency of bone marrow stromal cells was obviously higher that that in control group (P < 0.05-P < 0.01), and the effect was enhanced as the dosage increased. ③ The effect of ginsenoside Rgl on bone marrow stromal cells multiplication detected by MTT: The value of absorbance in experimental group was obviously higher than that in control group (P < 0.05-P < 0.01), and it was dose-dependent. CONCLUSION: Ginsenoside Rg1 had an effect of multiplication on pig's bone marrow stromal cells in vitro, and it was dose-dependent.

Objective To observe the curative effects of malignant brain swelling after brain injury by using the operations of standard large Craniotomy decompression and removal of necrotic brain tissues. Methods 80 cases of malignant brain swelling after severe brain injury were observed. The standard decompression surgery of large era-niotomy routine were used in 40 cases,while the operations of standard large craniotomy decompression and removal of necrotic brain tissues were used in the other 40 cases. The curative effects of the results after 15 days and six mon-ths were analyzed. Results The incidence of intracranial hypertension (37.5%, 15/40 ) and brain tissue incisional hernia (32.5% ,13/40)of the group using standard large craniotomy decompression and removal of nee-rotic brain tissues treatment was significantly lower than that of simple standard large craniotomy decompression treat-ment group [15.0% (6/40) vs 10.0% (4/40)] after 15 days (P<0.05 ). The prognosis excellent rate ( good + re-sidual) of the group using standard large Craniotomy decompression and removal of necrotic brain tissues treatment was significantly higher (60.0%) than that of simple standard large craniotomy decompression treatment group (40.0%) after six months (P<0.05 ). Conclusion The operations of standard large craniotomy decompression and removal of necrotic brain tissues can effectively reduce the intracranial hypertension of malignant brain swelling after trauma injury,and reduce mortality and morbidity of severe brain injury.

Objective To evaluate the performance of surgical approaches in the treatment of linear scleroderma of the head and face. Methods Forty-three patients with stable linear scleroderma of the head and face were included in this study. Surgical approaches, which included direct suture,skin flap translocation, soft-tissue augmentation and filling operation with dermal tissues, were selected and utilized alone or in combination according to the size, location and degree of atrophy and depression of lesions. Results After surgical treatment, wound dehiscence developed in one of these patients, but the wound healed after two sessions of suture. During one year of follow up, all the patients achieved favorite color, feeling and blood supply in the filling areas as well as good facial profile and visual appearance with no obvious convexity and concavity. Skin flaps matched well with surrounding tissues, incision lines were inconspicuous, and hairline looked naturally with well-distributed hairs in these patients after treatment. Patients were satisfied with treatment results. Conclusion Satisfied cosmetic outcomes can be achieved by using surgical approaches in patients with stable linear scleroderma of the head and face.
