[Objective]To research the method to repair dorsal skin defect of fingers by using retrograde neurocutaneous flap.[Method]Adopting nutrient vessels of 4 nerve branches in hands of radial-ulnar nerve as pedicle,the flaps were designed and applied to repair dorsal skin defect of fingers.[Result]All 10 flaps in 5 cases survived and wound area were covered.[Conclusion]Retrograde neurocutaneous flaps have sufficient blood supply,with no injury to nominous vesels,and with long distance to repair.Therefore,it is an advantageous method to repair dorsal skin defect,futhermore,two flaps could be used to repair skin defect of two fingers at the same time.

Objective To explore the difference of immunosuppresive effect between the expanded Stro-1+ and Stro-1-subgroups of human mesenchymal stem cells in vitro. Methods Mononuclear cells (MNCs) were isolated from bone marrow (BM) samples and seeded in a T-75 cm2 tissue culture flask contained with Dexter medium. When 50% confluence was obtained, adherent cells were collected and incubated with anti-stro-1 antibody, and the Stro-1+ and Stro-1-MSCs were further seeded for expansion. The total culture time (median) was 15 days. Cells were then analyzed by flow cytometry. One-way mix lymphocyte reaction (MLR) (1?105 responding cells and an equal number of stimulating cells/well were co-cultured in 96-well plates) and nonspecific mitogenic stimuli phytohemagglutinin (PHA) plus interleukin-2 (IL-2) induced lymphocytes proliferation (PBL 1?105/well were mixed with PHA 10?g/ml and IL-2 500U/ml in 96-well culture plates) were established in vitro. 1?103-3?104 irradiated Stro-1+ MSCs and Stro-1-MSCs were added into the two systems at the beginning of reaction. Immunosuppressive actions of both Stro-1+ or Stro-1-MSCs were compared. Results Adherent cells contained a median of 9% (range 5%-26%) Stro-1+ cells, which expressed higher immunophenotype of MSCs. In both reaction systems, suppressive actions occurred in a dose-dependent fashion when whatever Stro-1+ MSC or Stro-1-MSC were added. However, that the addition of 1?103 Stro-1-cells enhanced rather than inhibited the lymphocyte proliferation in one-way MLR. In the presence of various concentrations of MSCs, Stro-1+ MSCs always showed a significantly increased inhibitory effects in comparison to Stro-1-MSCs (P

35), while the expression level of TGF-?1 in Stro-1-MSC was significant higher than that detected in Stro-1+MSC (2-??Ct=0.39, P

In the recent years,infringement on patients' privacy in medical activities is drawing wider attention.In medical practice there exit some common phenomena of this kind,such as some medical staff spreading the information of medical record to irrelevant people,going beyond their duty to pry into or deliberately disclose patients privacy,intentionally harass of directly intrude upon patients' private parts,etc.These problems can be gradually reduced or avioded by strengthening medical staff's awareness of self-discipline,offering related education and advice to patients,and perfecting relevant laws and regulations.

Considering technology,regulations and other factors,nowadays we still use the records of print instead of in digital.《Electric Signature Law》makes a new environments for the study of electric medical records system.It regulates the writing,originally form and the save of electric medical records,affirms its value of evidence in court and prescribes what is dependable electric signature.

A 55 year old man complained of a painless mass at the left maxillofacial region. The mass had continuously grown over 10 years. Upon physical examination a cystic mass with size of 5 cm in length with bulging smooth surface was seen on the left maxillofacial region. Computed tomography (CT) scan showed a giant cyst with bone destruction and invasion in the left maxilla, maxillary sinus and nasal cavity. Needle aspiration of the mass yielded 80 milliliter of brown fluid. The excisional biopsy was made which revealed ghost cells and dysplastic dentin that were features of dentinogenic ghost cell tumor. Finally, a dentinogenic ghost cell was diagnosed.

AIM:To establish a method for determining saikosaponin A,paeoniflorin,hesperidin and ferulic acid in Chaihu Shugan Powder(Pericarpium Citri Reticulatae,Radix Bupleuri,Rhizoma Chuanxiong,Fructus Aurantii,Radix Paeoniae alba,etc.).METHODS:The chromatographic saparation was performed on a Hypersil C_(18) column(250 mm×4.6 mm,5 μm).The mobile phase was acetonitril-water(43:57)for saikosaponin A,and the mobile phase for rest components was acetonitrile-0.5% acetic acid(40:60).All of flow rates were 0.8 mL/min and column temperature maintained at 30℃.The detection wavelength was set at 200-400 nm.RESULTS:The four constituents were separated within 15 min.The linear ranges of saikosaponin A,paeoniflorin,hesperidin and ferulic acid were 38.5-166.7 μg/mL(r = 0.999 6),15.9～254.5 μg/mL(r = 0.999 9),22.1-353 μg/mL(r =0.999 3),6.30-201.5 μg/mL(r =0.999 9),respectively.The average recoveries were 97.57%,97.40%,98.86%,96.37%,respectively.The RSD were 2.1%,1.1%,0.70%,1.3%,respectively.CONCLUSION:The method is rapid,simple and accurate,and can be used for quality control of Chaihu Shugan Powder.

Objective To investigate the therapeutic outcome and its influencing factors after laparoscopic conservative surgery in treatment of tubal pregnancy. Methods From January 2003 to December 2008, 226 cases with tubal pregnancy were treated by laparoscopic conservative surgery. The tubal pateacy was evaluated in 152 cases given by hysterosalpingography (HSG) and 6 cases given by second laparoscopic exploration at 3-6 months after surgery. In their first laparoscopic surgeries, 209 got successful treatment and 19 underwent fail treatment. At 3-6 months after surgery, 89 cases with tubal patency among 207 cases with successful treatment were enrolled in group A. Nineteen cases who were failed in their first laparoscopic conservative surgery and treated by salpingectomy and 63 cases with tubal obstruction were enrolled in group B. The rate of tubal patency was calculated on patients with characteristics of gestational sac less or more than 5 era, the level serum human chorionic gonadotropin (hCG) less than 2000 IU/L,2000 IU/L to 5000 IU/L, and more than 5000 IU/L Results There was no significant difference in age,parity, amenorrhea, location of tubal pregnancy, rupture, pelvic adhesion between group A and group B.Two hundred and seven cases (91.6%, 207/226) were successfully treated at initial laparescopy. One hundred and fifty-two cases got follow up and 55 cases lost follow up at 3 to 6 months after surgery. There was statistical difference in preoperative hCG value which median were 980 (55-12 000) IU/L in group A,3150 (570-40 000) IU/L in group B(P<0.01); the diameter of tubal gestational sac were (3.4±1.3)cm in group A and (5.0±1.7) cm in group B(P<0.01); respectively, the volume of peritoneal bleeding were 200 (0-1500) ml and 300 (0-1600) ml, the rate of live tubal embryo was 2% (2/89) in group A and 11% (9/82) in group B, which all reached statistical difference (P<0. 05). Among 171 cases in both group A and 8, the rate of tubal patency were 65% (67/103) in 103 cases with maximal diameter of tubal gestational sac less than 5 cm and 32% (22/68) in 68 cases with maximal diameter of tubal gestational sac more than 5 cm, which reached statistical difference (P < 0.01). The rate were 72% (73/102) in patients with serum level of hCG less than 2000 IU/L, 29% (12/42)in patients with 2000 IU/L to 5000 IU/L and 15% (4/27)in patients with more than 5000 IU/L, which also showed statistical difference (P <0.05). It was observed that preoperative serum hCG level (OR=0.277, P<0.01), the maximal diameter of gestational sac (OR=0.577, P<0.01) and the volume of peritoneal bleeding (OR=0.999, P < 0.05) were significant factors influencing successful laparoscopy treatment by logistical regression analysis.Conclusion In order to preserve fertility, laparoscopic conservative surgery was a safe and feasible approach in treatment of tubal pregnancy. Preoperative serum hCG levels, size of tube gestational sac were significant factors influencing successful laparoscopic surgery.

Objective To study the curative effect of internal thoracic arterial chemoembolization in the treatment of advanced lung cancer.Methods Internal thoracic artery was confirmed to be the main supplied artery by digital substraction angiography(DSA) in 8 cases with lung cancer. The internal thoracic artery was embolized by stainless steel coil below the supplied segment in order to avoid the normal vascular territory occlusion.Then iodized oil combined with Cis-Diaminedichloroplatinum(DDP) and mitomycin(MMC) were injected into the supplied segment slowly until blood flow stopped,at last,the gelfoam sponge sheet was inserted into this supplied segment to decrease the wash of iodized oil by blood flow.Results Clinical symptoms were improved obviously in all cases after therapy.CT scans showed that iodized oil accumulated in the tumor better four weeks after the chemoembolization. Conclusion For these cases with advanced lung cancer which the blood supply mainly by internal thoracic artery,it is necessary to perform chemoembolization.
