OBJECTIVETo observe the short-term effect of patients with poly-infarctional vascular dementia (PIVD) treated by CT positioning scalp circum-needling (SCN) combined with Chinese herbal medicine.

METHODSEighty-nine patients of PIVD were enrolled and divided into the treated group (n = 57) and the control group (n = 32). They were all treated with oral taking of Fuyuan mixture (FYM, consisted of ginseng, medlar, salvia, bitter cardamon, etc). To the treated group, SCN was applied additionally with the unilateral area around the reflecting region (localized by CT) in scalp as main needling points and Ganshu, Shenshu, Zusanli, Hegu as supplementary points. Two courses of SCN were performed. The changes of clinical symptoms, intelligence and hemorrheological characteristics in patients were analysed.

RESULTSAfter two courses of treatment, the total effective rate in the treated group was 96.5%, which was better than that in the control group (75.0%), with significant difference (u = 2.423, P < 0.01); HDS scores increased in both groups after treatment, showing significant difference as compared with that before treatment (P < 0.01), hemorrheologic parameters were also apparently improved.

CONCLUSIONCT positioning SCN combined Chinese herbal medicine treatment has definite therapeutic effect in treating PIVD.

Objective To find out severity and types of syphilis infection in blood donors, attendants and persons to have their premrital medical examination in Zhoushan City and offer a new measure for prevention and treatment of syphilis. Methods Totally, 174 589 blood donors, attendants and persons to have their premarital medical examinations were screened preliminarily for inapparent syphilis with non-TPHA, and then TPHA was applied to confirm the diagnosis, according to the National Standard No. GB 15974-1995, combining with clinical symptoms and physical check-up. Results A total of 1 327 cases of syphilis from 174 589 samples tested, including blood donors, attendants and persons to have their premarital medical examinations, were diagnosed, with an inapparent infection rate of 7. 60‰ in average, 6. 42‰in males and 8. 74‰ in females, with a sex ratio of 0.71 (X2 = 29. 92, P

Objective To introduce an efficient method for culturing and purifying Schwann cells (SCs) in vitro. Methods Sciatic nerves were harvested from neonatal SD rats and the epineuria were removed. Single enzyme digestion combined with explans and double enzyme digestion were employed, respectively, to digest the nerve tissues following trituration. The proliferation of SCs and degree of purification were evaluated by viable count method and the combination of S-100 labeled monoclonal antibody and SCs. Results Proximally 3.5 × 106 cells were harvested with 96% survival rate and a purity of Schwann cells over 94% by single enzyme digestion combined with explans, however only 3.0×106 cells were gained with the purity being 90% and survival rate being 92% by double enzyme digestion. Conclusion This method yields large amount of viable Schwann cells with high purity and survival rate.

Objective To observe clinical curative effect of long-acting recombinant human growth hormone(rhGH)and short-acting rhGH,and their influences on growth and development indexes,serum thyroid function indexes and insulin in children with idiopathic short stature(ISS).Methods The children with ISS were randomly divided into long-acting group[subcutaneous injection of polyethylene glycol recombinant human growth hormone(0.2 mg·kg-1·w-1,qw)]and short-acting group[subcutaneous injection of recombinant human growth hormone(0.15 U·kg-1·d-1)at 30 min before sleep every night].All children were treated for 12 months.The growth and development[growth velocity(GV),height standard deviation of points(Ht SDS)],thyroid function,fasting insulin(FINS)and insulin-like growth factor-1(IGF-1)were compared between the two groups.The occurrence of adverse reactions was recorded.Results In the 68 children,there were 4 cases with loss to follow-up and shedding due to personal reasons.Finally,there were 33 cases in long-acting group and 31 cases in short-acting group for statistical analysis.After 6 months of treatment,GV in long-acting group and short-acting group were(4.53±0.56)and(3.97±0.48)cm·year-1,Ht SDS were-2.45±0.23 and-2.66±0.21,IGF-1 levels were(551.62±41.48)and(524.36±37.84)mg·mL-1,respectively.After 12 months of treatment,GV in long-acting group and the short-acting group were(9.44±0.82)and(8.46±0.77)cm·year-1,Ht SDS were-1.68±0.19 and-1.91±0.20,IGF-1 levels were(642.46±36.49)and(593.14±40.12)mg·mL-1,differences were statistically significant(all P＜0.05).There were no significant differences in FT3,FT4,TSH and FINS between the two groups after treatment(all P＞0.05).There was no significant difference in the total incidences of adverse drug reactions between long-acting group and short-acting group[6.06％(2 cases/33 cases)vs 12.90％(4 cases/31 cases),P＞0.05].Conclusion Compared with short-acting rhGH,promotion effect of long-acting rhGH is better on short-term growth and development in ISS children,which can increase level of serum IGF-1 and has no obvious effects on thyroid function,with good safety.

OBJECTIVETo understand the correlation between CD4+ cell count, HIV viral load (VL) and clinical characteristics among patients when HIV-1 was tested positive and initial AIDS diagnosis was made.

METHODS690 HIV-infected cases from Beijing Di-Tan Hospital were included and under a cross sectional study while SPSS statistical method was used.

RESULTSThe 690 HIV-infected cases would include 458 males and 232 females with age range from 2-72 years (mean age as 35.3). The modes of transmission showed that: homosexual contact taking up 17.5% while heterosexual was 16.7%. Most of the homosexual-infected ones lived in Beijing and most of them had bachelor or master's degrees. 19.4% of the transmission happened between heterosexual/bisexual couples, suggesting that HIV was transmitted through the "bridge population" while the rest were infected by contaminated blood/plasma. Many of the cases were identified when they lately visited the pre-operation surveillance point in the hospital. Serious immunodeficiency symptoms or signs were discovered as: CD4+ count < 50 cell/microl, serious opportunistic infections including pneumocystosis pulmonary, cerebral toxoplasmosis and cryptococcal meningitis. Higher frequencies of diseases seen were dermotosis, pneumonia, upper respiratory tract infection, hepatitis and digestive tract moniliasis.

CONCLUSIONBecause of the late identification of the disease, serious immuo-suppression situation often appeared, suggesting that there was an urgent need to improve STD/AIDS knowledge on those HIV (+) people so they might have an early access to accept medical care.

OBJECTIVETo investigate the constitution of abnormal spermatozoa from patients with sex chromosome anomalies.

METHODSTriple color fluorescence in situ hybridization (FISH) was used to determine the sex chromosome constitution of spermatozoa from three patients with sex chromosome anomalies (case 1:46,XY/47,XXY, case 2:45,XO/46,X,Yqh-, case 3:47,XXY). The preimplantation genetic diagnosis (PGD) was performed to case 2.

RESULTSAn increased ratio (2.05 vs 1) of X-bearing to Y-bearing spermatozoa was only observed in case 2, who also had an increased incidence of total abnormal spermatozoa (29.71%). An increased incidence of total abnormal spermatozoa (4.91%) was also observed in case 3. Among the constitution of abnormal spermatozoa, case 2 had the increased proportions of XY18 disomy, O18 monosomy and XO monosomy, while case 3 had an increase proportion of XY18 disomy (1.87%). PGD was performed to case 2 and one embryo with XX1818 was selected for implanting.

CONCLUSIONUsing FISH to detect the sperm sex chromosomes in patients with sex chromosome anomalies can provide the useful information to evaluate the risk of sex chromosome anomalies in preimplantation embryos.

OBJECTIVETo compare the protective activity of liver injury induced by D-galactosamine (GalN) between Huangqin-Tang and their metabolites by human intestinal bacteria(HIB).

METHODThe liver injuries in conventional and pseudo-germfree mice were induced by GalN. After oral administration of Huangqin-Tang and their metabolites mixtures by HIB, the serum transaminase (ALT and AST) activities were detected.

RESULTIn conventional mice, large and medium doses (20 and 10 g.kg-1) of Huangqin-Tang decoction significantly reduced the increase of serum ALT activity after 18 h GalN treatment. In pseudo-germfree mice, metabolites significantly reduced the ALT levels. However, Huangqing-Tang didn't affect the ALT levels in this kind of mice. To all of the animals, AST levels remained the same after oral Huangqin-tang or their metabolites.

CONCLUSIONThe metabolism by intestinal bacteria plays a role in pharmacological effects of constituents of Chinese herbal medicine. The metabolites of the constituents by intestinal bacteria were the real active components in vivo.
