Chinese herbal formulas can well present the characteristics of traditional Chinese medicine (TCM) with their simple, convenient, inexpensive and effective uses. However, due to the high cost of production, manufacturing pharmacies inside the hospital closed down one after another, which rendered the difficult situation of developing preparation of Chinese herbal formulas. The Pudong New Area of Shanghai, as a pilot region for comprehensive reforms on national development of TCM, vigorously explores the standardized research on and application of hospital-made Chinese herbal formulas. The Health Bureau of the Pudong New Area, based on the Shuguang Hospital, has established a clinical evaluation center for hospital-made Chinese herbal formulas. Through screening, manufacturing, quality control, unified allocation, and standardized clinical evaluation, the clinical evaluation center has summarized its experience on these processes.

Objective To explore the protective effect of L-carnitine on neonates with myocardial injury caused by as?phyxia. Methods Forty-four neonates with myocardial injury caused by asphyxia were randomly divided into L-carnitine treatment group (21 cases) and control group (23 cases). Patients in control group were received routine treatment and pa?tients in treatment group were given L-carnitine 0. 1 g/(kg · d) on the basis of routine treatment for 7 days. Symptoms and physical signs were observed before therapy and during the treatment in two groups. Before and after the treatment, plasma levels of free L-carnitine and cardiac troponin I (cTnI) were detected with the method of colorimetric assay and chemilumi?nescent, respectively. Results The clinical effective rate was significantly higher in treatment group than that of control group (90.48%vs 60.87%, P<0. 05). Compared with the control group, there was a significantly higher plasma concentra?tion of free L-carnitine in treatment group after treatment [(27.00±5.69)μmol/L vs (13.20±3.04)μmol/L, P<0.05]. In treat?ment group, plasma concentration of free L-carnitine was significantly higher after treatment than that of pre-therapy [(14.87 ± 3.95)μmol/L,P<0.05]. Compared with the control group, there was a significantly lower plasma concentration of cTnI after treatment in treatment group [(0.025±0.006)μg/L vs (0.046±0.010)μg/L, P<0.05]. In the treatment group, there was a significant correlation between decreased plasma concentration of cTnI and increased plasma concentration of free L-carnitine (r=0.899, P<0.05). Conclusion Administration of L-carnitine can effectively decrease the abnormal plasma lev?el of cTnI in neonates with myocardial injury caused by asphyxia, and thereby protect the myocardium.

Objective To establish a nerve stem cell model possessing the potentiality of differentiating intoγ-aminobutyric acid neuron-like cells(GABAergic-like cells),and provide eligible investigative vector for study on GABAergic neurons degenerative diseases. Methods Dibutyryl cyclic adenosine monophosphate (dbcAMP)was applied to induce human neuroblastoma SH-SY5Y cells,and the SH-SY5Y cells were divided into control group (0 mmol·L-1 dbcAMP),0.3 mmol·L-1 dbcAMP group,0.6 mmol·L-1 dbcAMP group,1.0 mmol·L-1 dbcAMP group and 2.0 mmol·L-1 dbcAMP group;the morphological changes of SH-SY5Y cells were observed.The Image-Pro Plus 5.0 software was used to measure the length of neurites of the neuron-like cells, and the percentage of the SH-SY5Y cells with neurites longer than 30 μm was calculated. The immunofluorescence cytochemistry technique was utilized to test GAD65 positive cells,and the positive rate of immune response was calculated.Results The results of light microscope observation showed that the cells in control group were polygonal,circular or shuttle type with smooth membrane and clear boundaries. With the increasing of the concentrations of dbcAMP and the prolongation of time,the morphology of SH-SY5Y cells’bodies became smaller with longer processes in dbcAMP groups.The cells interwined each other and showed mature neuron phenotype in 1.0 mmol·L-1 dbcAMP group.Compared with control group(31.4%±4.2%),the percentages of the cell with neurites longer than 30 μm in 0.3, 0.6, 1.0, and 2.0 dbcAMP groups (40.1%± 5.7%, 47.5%± 6.2%, 73.1%±3.2%,and 74.3%± 6.1%)72 h after induction were significantly increased(P<0.05 or P<0.01). Compared with control group (10.2%± 2.1%), the GAD65 positive expression rates in 0.3, 0.6, 1.0,and 2.0 mmol·L-1,dbcAMP groups(22.1%±2.4%,46.9%±3.2%,70.7%±3.4%,and 72.3%±3.7%)72 h after induction were significantly increased(P<0.05 or P<0.01).Conclusion The SH-SY5Y cells have the potentiality of differentiating into GABAergic-like cells, and 1.0 mmol · L-1 is the optimal concentration of dbcAMP.

Objective To discuss the common causes for postoperative complications after treatment of spinal fractures and their preventive measures.Methods To analyze the 32 failed eases who received internal fixation for their thoracolumbar fractures between July 1998 and April 2005 in our department.Their preoperative and postoperative results of X-ray,CT and MIR examinations were reviewed to find out the causes for failure.Three of them were treated through anterior approach and 29 through posterior approach.Eighteen screws broke in eight eases, the rods got loosened in eight cases and broken in four cases,15 pedicte screws were mis-located in eight cases and the implants got loosened in three cases.Results Thirty patients had to get a reoperation.Two were cured through non-surgical treatment.The causes for failure were found to be as follows:1,incorrect operation approach;2,in- stability of the front-middle colunm;3,unskillful operation;4,ignorance or the lesion to the adjacent vertebral discs; 5,flaws in pedicle screw design.Conclusion To prevent postoperative complications after internal fixation for spinal fractures,surgeons should strictly stick to the indications before operation,choose a proper approach and method for internal fixation,try to stabilize the front-middle column by the first intention,and have a good command of anatomy and operation skills.

OBJECTIVETo investigate the factors influencing the pregnancy outcomes of artificial insemination with donor sperm (AID), improve the pregnancy rate, and evaluate the safety of the offspring.

METHODSWe retrospectively analyzed 7,761 cycles of AID for 5,109 infertile couples performed between July 1, 2005 and June 30, 2013 in the Center of Reproductive Medicine of Shenyang No 204 Hospital, the outcomes of pregnancy, and the incidence of birth defects.

RESULTSTotally, 2 252 clinical pregnancies were achieved by AID, in which the pregnancy rate per cycle was 29. 02% and the cumulative pregnancy rate was 44. 08%. The clinical pregnancy rate was remarkably higher in the females of ≤ 35 years than in those of > 35 years old (30.31% vs 20.18%, P < 0.01), in the women with < 5-year infertility than in those with > 5-year infertility (30.83% vs 28.16%, P < 0.01), and in the patients of the ovarian stimulation group than in those of the natural cycle group (33.22% vs 28.68%, P < 0.01) The clinical pregnancy rate was the highest in the first treatment cycle (29.87%), with statistically significant difference from the fourth cycle (23.61%) (P < 0.05), but not between the other cycles (P > 0.05). There were 28 cases of birth defects in the offspring (1.40%), including 6 cases (21.43%) involving the cardiovascular system, 4 (14.29%) involving the musculoskeletal system, 3 (10.71%) involving the urogenital system, 3 (10.71%) involving the central nervous system, 2 cases (7.14%) of cleft lip and palate, 2 (7.14%) involving the respiratory system, 2 (7.14%) involving the gastrointestinal digestive system, and other anomalies.

CONCLUSIONFemale age, infertility duration, and ovarian stimulation treatment are important factors influencing the clinical pregnancy rate of AID. Artificial insemination with cryopreserved donor sperm does not increase the incidence of birth defects, which is considered as a relatively safe technique of assisted reproduction.

San'ao Decoction (SD) and its analogous formulas derived in the following generations are common used prescriptions for treating pulmonary diseases with principal symptoms such as cough and asthma. They are usually compatible with Chinese herbs for facilitating Fei, dispelling wind, resolving phlegm and fluid retention. Material bases in these formulas are mainly derived from Chinese drugs, but dissolution contents of active components are changed and new components are produced after compatibility. By multilevel effect evaluation, these analogous formulas all have commonness in ventilating Fei and superiorities of evidence-based derivation. The effect pathway of commonness was involved in cell structure protection, anti-inflammation, antioxidant, and immunoregulation.
