Objective To study of the effect of traditional Chinese medicine(TCM): Herba radix polygoni multiflori preparata (RPMP) on the cultured melanocytes(MC). Methods Extracts of TMC RPMP treated the cultured melanocytes, and tyrosinase activity, melanin level and proliferation of the cells were determined. Meanwhile, method of micropore filter was used to measure the ability of cell migration. Results TCM RPMP markedly promoted the proliferation and migration of MC in a dose-dependent manner at a range of 0~150?g/ml. Conclusions TCM RPMP can promote the proliferation and migration of MC in vitro. And it suggests that this drug could be used to treat vitiligo.

Objective To evaluate the clinical effects of scaling and root planning combined with application of the emodin thermosensitive hydrogel on periodontitis. Methods Forty patients with chronic periodontitis with a total of eighty teeth were included in the study.For each patient after scaling and root planning,the teeth on one side were assigned as the test group and treated with the emodin thermosensitive hydrogel in the pocket once a week for four weeks.The teeth on the other side were assigned as the control group.All the clinical parameters were recorded at the baseline,the 6th week and 12th week after the treatment. Results At the baseline,there was no difference in the clinical parameters between the test group and the control group(P>0.05).A statistically significant improvement of all clinical parameters was observed in both groups 6w later(t = 39.06、62.76、20.50、8.05、158.32、31.45、46.53、8.43、8.08、8.03)(P<0.01=,and all clinical parameters of the test group were better than those of the control group,the differences were statistically significant(t = 31.50、27.91、3.92、7.38、20.09)(P<0.01=. Conclusion The emodin thermosensitive hydrogel could effectively control the symptoms of periodontitis.

Objective To investigated the potential influences of poly(lactic-co-glycolicacid)(PLGA)scaffold as a platform on the differentiation of mouse bone-marrow stem cells to islet-like cells.Methods Mouse bonemarrow stem cells were grown and differentiated in culture with or without PLGA scaffold,and cell morphology and functions were compared within these groups.Results The PLGA scaffold showed fine biological compatibility.Differentiated islet-like cells were dithizone (DTZ) positive,insulin and C-peptide double positive,glucagon positive and somatostatin positive in both groups.Under electron microscope there were ultrastructures similar to that of islet β cells in cells of both groups.Cells with PLGA scaffold secreted more insulin under high level glucose stimulation (P<0.01).Conclusions PLGA scaffold was biologically compatible and improved function of the differentiated islet-like cells.

The impact of acupuncture for the pregnancy of in vitro fertilization-embryo transfer (IVF-ET) is discussed in the paper. Nowadays there are various conclusions about the impact of acupuncture for IVF-ET, and it may result from the differences in research designs. The effect is closely related to the demographic and clinical characteristics of subjects, such as age, the diagnosis of barrenness, blood flow index of uterine spiral arteries, the cycle of IVF, etc. Besides, the efficacy is influenced by treatment based on syndrome differentiation or not, the frequency and course of acupuncture in both the treating group and the control group, etc. If more reasonable design is achieved in the further study based on them, more reliable evidence will be provided for the effect and mechanism of the pregnancy of IVF-EF by acupuncture.

OBJECTIVETo investigate the blood supply of the pedicle fat grafts with the third lumbar segmental artery and its clinical effects on reoperation for lumbar disc herniation.
METHODSTwelve sides of 6 adult cadaver examples were contributed to investigate the courser of lumbar segmental vessels and the distribution of hypodermic capillary net of the dorsal branch of the third lumbar segmental artery. From January 2000 to January 2007,49 patients needed reoperation to treat lumbar disc herniation,including 26 males and 23 females with an average age of 55.6 years (ranged from 39 to 70 years). Duration between two operations ranged from 8 months to 15 years with an average of 6.9 years. Reoperative reasons included recurrent lumbar disc protrusion(30 cases)postoperative epidural scar formation (17 cases), postoperative epidural cyst formation (2 cases). Of them,9 patients underwent posterior lumbar interbody fusion at the second operation. The pedicle fat grafts with the third lumbar segmental artery were covered on the sites of the laminectomy in these patients. After negative pressure drainage tube were pulled out, 2 ml Chitsan were injected to the sites of the laminectomy and around epidural nerve root through epidural catheter. VAS score and the Oswestry Disability Index (ODI) were used to assess clinical outcomes before and after operation.
RESULTSThe courser of third lumbar segmental vessels were invariant at the lateral face of the lumbar vertebral body. The dorsal branch of the third lumbar segmental artery penetrated thoracolumbar fascia and formed rich hypodermic capillary net in the region. All patients were followed up from 5 to 8 years with an average of 5.6 years. VAS score of low back pain and leg pain decreased respectively from preoperative 7.6 +/- 1.2, 8.9 +/- 0.9 to 3.6 +/- 0.5, 3.0 +/- 0.4 at final follow-up (P < 0.01); and ODI score decreased from preoperative 44.1 +/- 6.2 to 13.9 +/- 3.6 at final follow-up (P < 0.01). According to ODI score to evaluate the clinical outcomes, 29 cases got excellent results, 11 good, 7 fair, 2 poor.
CONCLUSIONThe pedicle fat grafts with the third lumbar segmental artery and Chitsan can reduce epidural scar formation and prevent peridural fibrosis and adhesion and improve clinical effects of reoperation for lumbar disc herniation.

A new method for O-ethyl S-[2-( diisopropylamino) ethyl] methylphosphonothiolate ( VX) , sarin detection and its kinetic analysis based on piezoresistive microcantilever aptasensor was developed, where VX, sarin aptamers were immobilized on the microcantilever surface by biotin-avidin binding system. A linear relationship between the response voltage and the concentration of VX in the range of 2-60μg/L was obtained. The linear regression equation was △Ue=0. 886C-1. 039 (n=5, R=0. 984, p<0. 001) and the detection limit was 2μg/L ( S/N≥3 ) . A linear relationship between the response voltage and the concentration of sarin in the range of 10-60 μg/L was obtained, the linear regression equation was △Ue=0. 716C-2. 304 ( n=5, R=0 . 996 , p<0 . 001 ) and the detection limit was 10 μg/L ( S/N≥3 ) . The sensor showed no response for O-butyl methylphosphonochloridate, a structural analog of VX and sarin, which indicated high specificity and good anti-interference ability. On this basis, a reaction kinetic model based on receptor-ligand binding and the relationship with output voltage change was established. Response voltage (△Ue ) and response time( t0 ) were obtained from the fitting equation on different concentrations of VX, sarin fitted well with the measured values.

Objective To evaluate the clinical characteristics,diagnosis and treatment method of pancreatic sinistral portal hypertension caused by tumors in the body and tail of the pancreas.Methods A retrospective review of 40 patients diagnosed with pancreatic sinistral portal hypertension at Peking Union Medical College Hospital from January 2007 to December 2012 was performed.Results The Initial symptoms were epigastric pain and discomfort (n =12),emaciation (n =5),low-back pain (n =4),splenomegaly (n =2),hematemesis and melena (n =4),hypoglycemic coma (n =1).All 40 patients had splenomegaly and varices in the gastric fundus with normal liver function.8 had combined esophageal varices.24 had hypersplenism and 26 had elevated serum CA19-9 level.25 patients received surgical intervention and 15 were treated conservatively.Pathology confirmed malignancy in 29 patients and benign lesions in 11.Thirty-five patients (35/40,88%) were followed up for 12 to 72 months.For patients undergoing surgery,hypersplenism and varices in the gastric fundus were all relieved.There was no upper gastrointestinal bleeding occurred during follow-up.For patients treated conservatively,hypersplenism remained stable and among them 4 patients had upper gastrointestinal bleeding,and successfully treated by medication,therapeutic endoscopy and interventional therapy.Conclusions Patients with pancreatic sinistral portal hypertension caused by tumor in the body and tail of the pancreas can be cured successfully by surgery.In those patients portal hypertension can present as initial clinical manifestation.
