OBJECTIVETo observe the curative effect of Qianjin Kouchuang Jiawei Granule (QKJG) on recurrent oral ulceration [yin deficiency fire excess type (YDFET)].

METHODSTotally 120 patients who suffered from recurrent oral ulceration (YDFET) were randomly assigned to two groups, the experiment group and the control group, 60 in each group. Patients in the experiment group took QKJG, 20 g each time, twice per day, while those in the control group took Kouyanqing Granule (KG) , 20 g each time, twice per day. Fourteen days consisted of one therapeutic course, two for all. Scores for patients' symptoms and signs (ulcer area, exudation, hyperaemia, edema, the number of ulceration, burning sensation, and pain degrees) were assessed before treatment, at day 3 and 7 after treatment. Short-term efficacy was assessed by visual analogue scale (VAS). The total paralysis time and the total number of ulceration at month 12 after treatment were taken as judgment for long-term efficacy. Results Compared with before treatment in the same group, symptoms and signs were obviously improved at day 3 and 7 after treatment in the two groups (P < 0.05). Compared with the control group at day 3 after treatment, the improvement of edema, exudation, pain degree, and burning sensation was more obvious in the experiment group (P < 0.05, P < 0.01). The improvement of edema, pain degree, and burning sensation at day 7 after treatment was more obvious in the experiment group than in the control group (P < 0.05). As for short-term efficacy, the total effective rate was 86.67% (52/60 cases) in the experiment group and 83.33% (50/60 cases) in the control group, with no statistical difference between the two groups (P > 0.05). As for long-term efficacy, the total effective rate was 90.00% (54/60 cases) in the experiment group, significantly higher than that of the control group with statistical difference [81.67% (49/60 cases), P < 0.05]. At month 12 after treatment, the total number of ulceration was reduced and the paralysis time of ulcer attack prolonged in the experiment group, with statistical difference when compared with the control group (P < 0.05).

CONCLUSIONQKJG showed better long-term efficacy than that of KG in treating recurrent oral ulceration (YDFET).

Methods A total of 28 patients of 0,I,II stage breast cancer were implanted with silicon gel prosthesis immediately after they underwent skin-sparing modified radical mastectomy. NAC conservation depended on frozen section result. Results NAC of all the 28 patients were conserved. During 2-18 months (median15 months) follow-up, bilateral breasts were symmetrical and in good appearance with a 96.5% excellent rate. No local recurrence, distant metastasis or obvious complications occurred. Conclusions Immediate breast reconstruction with subpectoral implantation of silicon gel prosthesis after NAC sparing modified radical mastectomy is proven to be an effective and safe method with the advantage of good appearance and shorter recovery time in early-stage breast cancer.

OBJECTIVETo explore the role of tumor necrosis factor-alpha (TNF-alpha) in the pathogenesis of hepatorenal syndrome.

METHODSBy isolated perfused kidney technique, rat kidneys were perfused at a constant flow. Changes in perfusion pressure (mmHg) were consecutively measured with multi-functional physiology recorder. After TNF-alpha or heparin treated 90 minutes, the perfusion pressure stimulated by endothelin-1 (ET-1) was detected.

RESULTSTNF-alpha and heparin didn't modify the baseline perfusion pressure. When ET-1 was added at 2 nmol/L, the perfusion pressures increased to (47+/-9) mmHg, (97+/-36) mm Hg and (11+/-6) mm Hg in control, TNF-alpha and heparin (10mg/L) treated group, respectively, which were different among the three groups (t>or=3.811, P<0.01). No pathological damages were found in kidney tissues from all the groups after being stained with hematoxylin/eosin.

CONCLUSIONTNF-alpha plays an important role in the pathogenesis of hepatorenal syndrome by promoting renal vasoconstriction.

Objective To explore the changes of CD40 and CD40 ligand(CD40L) levels and investigate their significances in children with graft-versus-host disease(GVHD)after related-donor human leukocyte antigen(HLA) matching allogeneic hematopoietic stem cell transplantation(HSCT).Methods Nineteen patients with ?-thalassemia major and 1 patient with congenital inherent hemolytic anemia accepted umbilical cord blood transplantation(UCBT) and allogeneic peripheral blood stem cell transplantation(allo-PBSCT),respectively,and all cases were received successfully related-donor human leukocyte antigen matching allogeneic HSCT.Peripheral blood samples were obtained before and after transplantation,the time when GVHD happened,the expressions of CD40 and CD40L were measured by using immunofluresence asssy.Results Four UCBT children and 3 allo-PBSCT children had no acute GVHD.Thirteen children had acute GVHD(degreeⅠ-Ⅳ),the expressions of CD40L on CD4+ and CD8+ T cells in the patients with acute GVHD increased,especially in allo-PBSCT.Five cases of UCBT and 12 cases of allo-PBSCT patients had chronic GVHD,the expressions of CD40L+,CD25+ and CD69+ on CD4+ and CD8+ T cells in patients with chronic GVHD increased obviously.The expression of CD19+CD40+ was lower than normal within 3 months after transplantation.Conclusions The high expression of CD40L+T cells in periferal blood after HSCT was related to the activation and proliferation of T cells in the development of GVHD in HSCT.

Professor Shao Jing-ming had practiced Chinese medicine for more than 80 years with rich clinical experience and exquisite acupuncture techniques. From his clinical experience, Professor Shao's clinical features can be summarized as the followings: attaching importance to the theory of meridians and collaterals, combining pattern identification and disease identification, using fewer acupoints for treatment, and using Ashi point and Hegu (LI 4) to treat goiter. He emphasized the priority and sequence in acupoint-selection and manipulation. In treatment of epilepsy, he proposed to treat it according to the situation and paid great attention to the special function of the extraordinary acupoints. During the onset, it should be managed by calming the mind and controlling the symptoms; during the remission period, acupuncture and drugs should be applied simultaneously to regulate qi-blood and yin-yang, so as to reduce the frequency of attacks. He believed that acupuncture manipulation be one of the key factors in achieving the efficacy. In treatment of the motive diseases, such as convulsions and cramps, acupuncture with static and longer needle-retaining time should be adopted to control the limb movement, to strengthen the stimulation and to obtain a long-term efficacy. Professor Shao Jing-ming's medical records range from internal medicine, external medicine, gynecology and pediatrics, listing various refractory diseases effectively treated by him. Professor Shao was a moral and erudite Chinese medicine master, and his clinical experience is worthy of inheritance and development.
