Objective To explore the effect of the transplantation of intact follicle by punching with syringe needle on defect eyebrow reconstruction.Methods Fifty-two patients with eyebrow defects due to burn,trauma,resection and inappropriate eyebrow trimming were recruited,35 with bilateral defects and 17 with unilateral defect.The scalps strips from the safe donor area or temporal region were taken and made into 1 to 2 cm long hair with intact follicle under 3 fold magnifier.The recipient area was punched with 21G or 22G syringe needle.Then the hair shaft was clamped with mi croforceps and the follicles were transplanted to the defective area.Results Folliculitis were found in two burn patients after the transplantation and cured by alcohol inunction.Hairs of the rest patients transplanted grew well.The direction and appearance were satisfied.The survival rate of hair was more than 90 ％.Conclusions It is feasible to restore the partial eyebrow defect by intact follicular transplantation by punching with syringe needle and clamping the hair shaft with microforceps.

A total of 105 patients with ketosis-onset diabetes were divided into four groups (A+B-,A + B +,A - B -,A - B +) based on the results of islet-associated autoantibodies (A +,A - ) and β-cell function (B +,B - ).Nearly 94％ patients in the A -B + group and 1/10 patients in the A - B - group were non-insulin dependent.While in the A + B - and A + B + groups,the detection rates of subsequent non-insulin dependency were 20％ and 58％,respectively.Among the four groups,patients in the A - B + groups had a lower level of IL-6 and a higher level of TNF-α. Patients in the A + B - and A + B + groups had a higher level of IL-18.Our study indicates that patients with ketosis-onset diabetes may present different clinical characteristics. Evaluate the islet-associated autoantibodies and pancreatic β-cell function may be helpful to the clinical diagnostic and therapeutic strategies in diabetes.

A rapid, sensitive and simple liquid chromatography-tandem mass spectrometric (LC-MS/MS) method was developed for the simultaneous determination of yogliptin and its metabolite in Wistar rat plasma. Linagliptin and dexamethasone were chosen as the internal standards of yogliptin and its metabolite, (R)-8-(3-hydroxypiperidine- -yl)-7-(but-2-yn-1-yl)-1-((5-fluorobenzo[d]thiazol-2-yl)methyl)-3-methyl- H-purine-2, 6 (3H, 7H)-dione, respectively. After a simple protein precipitation using acetonitrile as the precipitating solvent, both analytes and ISs were separated on a Grace Altima HP C18 column (2.1 mm x 50 mm, 5 microm) with gradient elution using methanol (containing 0.1% formic acid, 4 mmol x L(-1) ammonium acetate)-0.1% formic acid (containing 4 mmol x L(-1) ammonium acetate) as the mobile phase. A chromatographic total run time of 4.4 min was achieved. Mass spectrometric detection was conducted with electrospray ionization under positive-ion and multiple-reaction monitoring modes. Linear calibration curves for yogliptin and its metabolite were over the concentration range of 0.5 to 500 ng x mL(-1) with a lower limit of quantification of 0.5 ng x mL(-1). The intra- and inter- assay precisions were all below 14%, the accuracies were all in standard ranges. The method was used to determine the concentration of yogliptin and M1 in Wistar rat plasma after a single oral administration of yogliptin (27 mg x kg(-1)). The method was proved to be selective, sensitive and suitable for pharmacokinetic study of yogliptin and M1 in Wistar rat plasma.

BACKGROUNDTo study the effect of gene amplification and selection system with DHFR plus GS and DHFR or GS gene on the foreign gene expression.

METHODSUsing the N-terminal truncated hTPO(T184) gene as target gene, two plasmidsre were constructed: pDC- T184 and pGC-T184 where DHFR and GS gene were used respectively as the selective amplification marker. They were cotransfected into CHO dhfr cells to establish dual gene amplification and selection system of DHFR plus GS gen and respectively transfected to establish single gene amplification and selection system of DHFR or GS gene. Three selective methods in dual selective system to compare expression efficiency of hTPO were designed: the first method (DG) was to use drug pressure of MTX, then use MSX; the second method (GD) was reversed; the third method was simultaneously to use MTX and MSX as drug pressure.

RESULTSDHFR+GS dual system had not only higher gene amplification efficiency but also higher level expression. There was no distinct affect in different method of drug pressure.

CONCLUSIONSMTX plus MSX dual drug pressure in dual selection system was an efficient and simple method to increase the expression of foreign gene in mammalian cells.

OBJECTIVE: To observe the effects of abdominal acupuncture and the periodic therapy of Chinese herbal medicine on follicular development and endometrial receptivity in the patients with infertility induced by ovulation failure and differentiated as kidney deficiency in TCM. METHODS: A total of 84 patients with infertility induced by ovulation failure and differentiated as kidney deficiency were randomized into a combined therapy group (27 cases), an abdominal acupuncture group (27 cases) and a western medication group (30 cases). In the combined therapy group, abdominal acupuncture and the periodic treatment of Chinese herbal medicine was provided. In the abdominal acupuncture group, the simple abdominal acupuncture therapy was used. In the western medication group, clomiphene citrate (CC) and human chorionic gonadotrophin (HCG) prescribed. The treatment for one menstrual cycle was taken as one session and 3 sessions of treatment were required except the pregnancy. The folicle development, endometrial thickness and morphology, menstrual condition and TCM symptom score were observed before and after treatment in the three groups, and the clinical efficacy was evaluated. RESULTS: After treatment, the ovulation was recovered to different degrees in the three groups. The ovulation rate was 59.3% (16/27) in the combined therapy group, 55.6% (15/27) in the abdominal acupuncture group and 53.3% (16/30) in the western medication group. The difference was not significant in comparison among the three groups (>0.05). After treatment, the endometrial thickness in the periovulatory period was increased as compared with the thickness before treatment in the combined therapy group and the abdominal acupuncture group (both <0.05). After treatment, the endometrial thickness in the combined therapy group was higher than the western medication group (<0.05). In comparison before and after treatment, the difference in the endometrial morphology was significant in the combined therapy group and the abdominal acupuncture group (both <0.05). In comparison between the combined therapy group and the western medication group, the difference in the endometrial morphology was significant after treatment (<0.05). After treatment, the menstrual condition and TCM symptom score in the combined therapy group and the abdominal acupuncture group were all improved as compared with those before treatment (all <0.05). The score of menstrual condition in the combined therapy group was higher than the western medication group (<0.05) and TCM symptom score in the combined therapy group and abdominal acupuncture group was higher than the western medication group after treatment (all <0.05). The total effective rate was 88.9% (24/27) in the combined therapy group and was 92.6% (25/29) in the abdominal acupuncture group, which was higher than 56.7% (17/30) in the western medication group (<0.01). There was no adverse reaction in the combined therapy group and the abdominal acupuncture group. CONCLUSION Abdominal acupuncture combined with the periodic therapy of Chinese herbal medicine improve the menstrual condition and relieve the clinical symptoms of infertility induced by ovulation failure of kidney deficiency in the patients and the therapeutic effects are better than the medication with CC + HCG. This combined therapy improves the ovulation rate and the endometrial receptivity at periovulatory stage to increase the pregnancy rate. There is no adverse reaction discovered in clinical practice.
