Objective: To investigate the application of microemulsion TLC in separation and identification of various effective compositions in traditional Chinese patent medicines. Methods: The various compositions in Kangganmao Granules and Fangfeng Tongsheng Pills were separated and identified simultaneously on polyamide film with six kinds of SDS/n C 4H 9OH/n C 7H 16 /H 2O microemulsions as the mobile phases. Affections of kinds and acidity on separationg results of microemulsions were investigated. Results: The baicalin, chlorogenic acid, Saposhnikovia and glycyrrhiza in Kangganmao Gronules and the emodin, chrysophanol, baicalin, Saposhnikovia and Glycyrrhizae in Fangfeng Tongsheng Pills may be separated and identified simultaneously with microemulsion (containing 75% water) formic acid (9∶1) as mobile phase. Conclusion: Microemulsion TLC is an efficient, simple new method for the separation and identification of various compositions in traditional Chinese patent medicines.

A total of 40 adult black-mice was used and divided into two groups for expeiment. Group A was irradiated by UVB only and Group B had SPF 15 sunscreen a.pplied to the back followed by irradiation by UVB. Each group was divided again into 5 subgroups according to the days of UVB irradiation frcm 2 to 10 days. A Waldmann combination UVA+UVB Radiation Treatment Cabin 8001 was used as the light source and the UVB dosage was 50 mJ/cm2 daily. Skin specimens were taken 24 hours after the last irradiation. Histologic changes in epidermis were reviewed by the light microscope. In group A, the characteristic sunburn cells(SBC) were observed with 100 mJ/ cm2. SBC number was maximum with 400 mJ/cm2. The other epidermal changes were parakerat.osis, crusts, atypical cells, and mitoses of basal cells, which showed graded responses to the UVB doses. Pretreatment with the sunscreen completely prevented these changes.

OBJECTIVE: Hysterectomy is one of the most common gynecological operations. The objective of this study is to compare the efficacy of suturing methods of vaginal cuff between laparoscopic and vaginal approach. METHODS: One hundred and sixty one cases of laparoscopic hysterectomy were devided into two groups. In group A(n=67), vaginal cuff was sutured by laparoscopic suture technique and in group B(n=94), vaginal cuff was repaired by vaginal approach. RESULTS: There were no significant differences in uterine weight, hospital stay, pre-and postoperative hemoglobin level and complications including febrile morbidity in two groups. Operation time was significantly shorter in group B(p=0.05). CONCLUSION: Transvaginal repair of vaginal cuff showed shorter duration of operation time than laparoscopic suture technique in total laparoscopichy sterectomy.

We experienced three cases of non-giant congenital nevus. They showed zosteriform or heart-shaped grouping of pigmented papules which were pierced by hairs. Histopathologic examination disclosed nevus cell infiltration in and around hair follicles and in the upper two thirds of reticular dermis. We would like to report these cases as follicle-centered spotted grouped pigmented nevi.

OBJECTIVES: Cell adhesion molecules may play a role in integrating amnionic membrane. The objective of this study was to prove E-cadherin mRNA and proteins in cultured human amnionic cells. METHODS: We cultured amnionic cells from 4 women undergoing cesarean section without labor. E-cadherin was determined by immunohistochemistry and Western ligend blotting. To demonstrate E-cadherin mRNA, reverse transcription-polymerase chain reaction was performed. RESULTS: On immunohistochemistry, E-cadherin was abundantly showed on the cytoplasm of the cells. Western ligend blotting showed clear 120 kDa bands on four specimens, and relatively weak band on one specimen. Reverse transcription-polymerase chain reaction showed 432 BP bands. CONCLUSION: We proved E-cadherin and its mRNA by immunohistochemistry, Western ligend blotting and reverse transcription-polymerase chain reaction in cultured human amnionic cells.

OBJECTIVETo compare the therapeutic effects between close reduction and plaster slab fixation combined with plaster external traction and operation for the treatment of pediatric closed Gartland type III supracondylar humerus fractures without neurovascular injury complications.

METHODSFrom June 2009 to June 2012, 151 children with closed Gartland III supracondylar humerus fractures were retrospectively studied and divided into two groups, including 87 boys and 64 girls, ranging in age from 1 to 12 years old with an average of 5.3 years old. Among them, 76 children (conservative group) were treated with close reduction and plaster slab fixation combined with plaster external traction; 75 children (operation group) underwent surgical operation. The time of elbow joint function exercise, the healing time of fracture, the function recovery of elbow joint and carrying angle was recorded and analyzed. The therapeutic effects were evaluated by the Flynn criteria system.

RESULTSAll patients were followed up from 6 to 36 months (18.3 months on average). The average time of fracture healing and elbow joint functional exercise of the conservative group was shorter than those of operation group (P < 0.001). Motion range of the elbows and carrying angle of two groups were no statistical difference (P > 0.05). According to Flynn criteria system, in conservative group, the result was excellent in 31 cases, good in 35, fair in 7, and poor in 3; in operation group, 27 in excellent, 30 in good, 17 in fair and 1 in poor; there was no significant difference between two groups in therapeutic effects (P > 0.05).

CONCLUSIONClose reduction and plaster slab fixation combined with plaster external traction in treatment of pediatric closed Gartland type III supracondylar humerus fractures without neurovascular injury complications,which has similar effect to surgical treatment, and the time of fracture healing and elbow joint function exercise are significantly shorter.
