Objective To investigate the effect of meridian point cosmetic therapy of traditional Chinese medicine(TCM)on acne.Methods 80 cases of acne patients were selected and divided into the treatment group(50 cases)and the control group(30 cases).The treatment group was given medication by differentiation of symptoms and signs and designed a complete treatment scheme by the demonstration of health analysis curve through test by balanced cosmetic equipment and meridian point of TCM.The control group only received extravenous medication.The effect of the two groups was observed after 2 months' treatment.Results The total effeetive rate in the treatment group was 94.0%,which was superior to that of the control group(73.3%),x2=11.08,P＜0.05. Conclusion Application of meridian point cosmetic therapy of TCM could facilitated the diagnosis and treatment by differentiation of symptoms and signs and thus improve the curing rate.

Objective To investigate the immunoregulatory effects of mesenchymal stem cells (MSCs) on the peripheral T-lymphocytes of lupus nephritis in vitro. Methods MSCs were isolated and expanded from human bone marrow cells. The purity of MSCs was identified by flow cytometry (FCM). The MSCs (4×104, 1×104, 2×103) were added into wells containing peripheral blood lymphocytes (2×105) from lupus nephritis in the presence of phytohemagglutinin [PHA). Samples were divided into the following groups: group A:T-lymphocytes alone; group B: MSCsl with T-lymphocytes(MSCsl:T=1:5); group C: MSCs2 with T-lymphocytes (MSCs2:T=1:20); group D: MSCs3 with T-lymphocytes (MSCs3:T=1:100). The proliferation of T-lymphocytes was assessed by MTT. FCM was used to analyze the apoptosis of T-lymphocytes and surface markers of CD28 and CD152. The gene expression of interferon γ (IFN-γ), interleukin-10 (IL-10), transforming growth factor-β1 (TGF-β1) were detected by real-time RT-PCR. Results In vitro, with the presence of MSCs, peripheral blood T-lymphocytes from lupus nephritis were statistically significantly decr-eased in their proliferative activities , apoptosis and CD28 expression in a dose-dependent manner. No inhibitory effects on CD152 expression of T-lymphocytes had been observed . MSCs promoted the gene expression of TGF-β1 and inhibited the gene expression of IL-10, IFN-γ. Conclusion MSCs can inhibit the proliferative activities, apoptosis and CD28 expression of peripheral blood T-lymphocytes of lupus nephritis, increase gene expression of TGF-β1 and lower the gene expression of IL-10, IFN-γ, which may play an important role in it's immunosuppressive effects on lupus nephritis.

Objective To probe the value of multi-slice spiral CT angiography (MSCTA) in decreasing surgical trauma of the cranial base meningioma. Methods Thirty-two patients with cranial base meningioma were examined preoperatively with MSCTA to observe the shape and the relationship with the adjacent vessels and the skull base. Three-dimensional images were reconstructed to imitate the approach of operation and compared with surgical findings. Meanwhile, 22 patients withnot MSCTA were selected randomly as control group. The amount of blood transfusion and the occurrence rate of complications were compared between the two groups. Results MSCTA depiceted clear three dimensional images of the meningioma and the relationship with the adjacent vessels and the skull base, corresponded very well to the surgery. By imitating the operation, all patients were designed the incision size of bone appropriately, the vessels of peritumoral were kept off effectively and the risk of the embedded vascular were assessed accurately. The conventional surgical approach and method were changed in 9 patients, 4 formulated the planning of the sub-total resection and radiotherapy preoperatively. Compared with control group, the amount of blood transfusion reduced significantly (P<0.05) and postoperative complications decreased. Conclusion MSCTA can imitate the surgical operations in multi-angle and supply the vital information for choosing the proper surgical approach, thereby reducing surgical trauma and postoperative complications.

OBJECTIVE: To summary the clinical characteristics and outcomes of nasal inverted papilloma treated by intranasal endoscopic approach. METHOD: Fourty-six patients with nasal inverted papilloma were treated with endoscopic surgery from 1995 to 2005. There were 34 males and 12 females, age ranged from 18 to 76 years old. The period of follow-up was 12-72 months. RESULT: Only 5 cases recurred within 24 months after the surgery. The other cases had no recurrence during the follow-up period. CONCLUSION The endoscopic endonasal approach is an effective treatment for an inverted papilloma in selected cases. A combination of Caldwell Luc procedure and transnasal endoscopic sinus surgery may be needed for those patients with inverted papilloma in stage III.

Objective To investigate the protective effect and mechanism of serum containing Euonymus fortunei on the rat pancreatic islet cells. Methods Forty male SD rats were randomly divided into 5 groups (n=8 in each group), including the control group (normal rat islet cells were cultured with normal rat serum), ischemic preconditioning group (abdominal aorta was blocked first and then re-opened before the pancreas was obtained, and the pancreatic islet cells were cultured with normal rat serum), Euonymus fortunei treatment group (normal rat islet cells were cultured with rat serum containing Euonymus fortunei), Euonymus fortunei group and blank group (normal rats were administered orally with Euonymus fortunei extract or distilled water for the preparation of rat serum). Diphenylthiocarbazone (DTZ) staining was utilized to observe and calculate the quantity of islets. Acridine orange (AO)/propidium iodide (PI) staining was adopted to calculate the survival rate of islet cells. The insulin release experiment was performed to calculate the stimulation index (SI) and evaluate islet cell function. The concentration of glutathione (GSH) and nitric oxide (NO) in islet cells was detected using GSH and NO kits. The expression level of inducible nitric oxide synthase (iNOS) messenger RNA (mRNA) was quantitatively measured by reverse transcription polymerase chain reaction (RT-PCR). Results Islet cells were observed in specifically scarlet color after DTZ staining. The quantity of islet cells did not significantly differ among different groups (all P>0.05). Along with the prolongation of culture time, the activity of islet cells in each group was gradually decreased. At 72 h after isolation and culture, compared with the control group, the survival rate of the cells was significantly higher in the Euonymus fortunei treatment group (P<0.05). The insulin release test results demonstrated that compared with the control group, the SI of the ischemic preconditioning and Euonymus fortunei treatment groups was significantly increased (both P<0.05). Compared with the control group, the GSH contents of pancreatic islet cells in the ischemic preconditioning and Euonymus fortunei treatment groups were considerably enhanced, the NO content was significantly decreased, and the expression level of iNOS mRNA was significantly down-regulated (all P<0.05). Conclusions Euonymus fortunei can increase the survival rate of islet cells and enhance the function of pancreatic islets by increasing the level of GSH, down-regulating the expression of iNOS and decreasing the NO production.
