OBJECTIVETo observe the effect of combined therapy of Neiyi pill (NP) and Neiyi enema (NE) on endometriosis and its effect on serum levels of endometrial antibody (EMAB) and carcinoembryonic antigen 125 (CA125).

METHODSFifty-eight cases with endometriosis were divided into 3 groups randomly, group A (n = 16) treated by NP, group B (n = 24) treated by NP and NE, and group C (n = 18) treated by danazol, all for 3 menstrual cycle with single blind method. The effect was observed and the serum levels of EMAB and CA125 were detected before and after treatment.

RESULTSComparison of the efficacy between the 3 groups showed: there was no remarkable difference between group A and B (P >0.05), both of group A and group B were superior to that of group C (P<0.05). The levels of EMAB and CA125 had no significant changes in all the three groups after treatment.

CONCLUSIONCombined therapy of NP and NE could improve the curative effect on endometriosis, and without obvious effects on serum levels of EMAB and CA125.

Objective To identify changes in the occurrence of endemic fluorosis in order to provide scientific basis for making countermeasures. Methods Five villages from 14 counties of mild, moderate and severe fluorosis affected areas were selected by stratified cluster sampling every year in the whole province during 2006 - 2010. Water and urinary fluorine were determined by ion selective electrode method(GB/T 8538-1995); dental fluorosis of children 8-12 years old was diagnosed with Dean method; skeletal fluorosis was diagnosed according to "clinical indexing standards of endemic skeletal fluorosis "(GB 16396-1996), between 2006 and 2008, and "clinical diagnosis standard of endemic skeletal fluorosis"(WS 192-2008) between 2009 and 2010. Results A total of 25 diseased villages were surveyed, 14 with water sources changed, covered a resident population of 8005 people, beneficiary population 7154, and accounting for 89.37% of the resident population; not changed villages 11. In accordance with the "State drinking water health standards", in the 14 changed villages the fluoride in drinking water was qualified (≤ 1.20 mg/L), there were 3 schools whose water fluorine content exceeded the standard; among the 11 villages that did not change water sources 7 drinking water samples fluorine content exceeded the standard. Of the 8 to 12 years old children in villages with changed water sources, 363 of them were checked and 142 dental fluorosis were found, the detection rate of dental fluorosis was 39.12% (142/363); in villages with water sources not changed, 303 children were checked, the detection rate of dental fluorosis was 43.89%(133/303). Of sixteen and elder adults in water source changed villages, 6424 people were checked and 403 skeletal fluorosis were found, skeletal fluorosis detection rate was 6.27% (403/6424); 3572 people were checked in not changed villages, the detection rate of skeletal fluorosis was 13.89%(496/3572). In water sources changed areas, geometric mean of urinary fluoride was in the normal reference value(WS/T 256-2005, 1.40 mg/L)or less. Conclusions Endemic fluorosis is decreased in water improved areas, but in unimproved areas the disease is still severe, and control of endemic fluorosis is still an arduous task.

OBJECTIVETo investigate the effects of catecholamine hormone on the blood and brain of heroin addicts.

METHODSRats were divided into three groups and treated with the glucose (control group), the heroin (im) (heroin group), and the combination of the intramuscular injection of reserpine and heroin (reserpine group). Changes in the levels of the dopamine (DA), cAMP, and cGMP were detected by the radioimmunoassay (RIA) method in the blood and brain tissue.

RESULTSNo significant withdrawal symptoms were observed in the reserpine group. Compared with the control and heroin groups, the blood cAMP levels were increased by 35.36% and 15.53% in the reserpine group, respectively; the cAMP levels in the midbrain ventral tegmental area (VTA), prefrontal cortex (PFC), and hippocampus (Hipp) were increased by 24.08% & 8.53%, 15.66% & 8.13%, and 21.95% & 8.40%, respectively. While compared to the control and heroin groups, the DA levels of the PFC, Hipp, striatum, and nucleus accumbens (NAc) were significantly reduced in the reserpine group, decreasing by 74.09% & 82.86%, 81.06% & 82.23%, 91.62% & 86.55% and 84.35% & 90.63%, respectively. The concentrations of cGMP of the brain tissues in the reserpine group were lower than those in the control group. In addition, the neural electrophysiological testing showed that the electroencephalogram (EEG), electrocardiogram (ECG), and muscle spindle discharge diagram of rats in both the reserpine and heroin groups were apparently changed.

CONCLUSIONCatecholamine hormone plays an important role in heroin addiction.

OBJECTIVETo study the condition and clinical characteristics of Epstein Barr virus (EBV) infection in hospitalized children from Wuhan region.

METHODSA total of 14 840 hospitalized children were classified into five age groups: less than 6 months old, 6 months to 1 year old, 1 to 3 years old, 3 to 7 years old and 7 to 15 years old. The antibodies IgM and IgG to EBV capsid antigen (VCA) were detected using ELISA.

RESULTSIn the 14 840 hospitalized children, 7 899 were positive for EBV antibodies, with an infection rate of 53.23%. The positive rate of VCA-IgM was 4.05% (601/14 840) and that of VCA-IgG was 49.18% (7 298/14 840). The lowest positive rate of VCA-IgM (0.11%) was found in the group of less than 6 months old and the highest positive rate of VCA-IgG (79.83%) was found in the group of 7 to 15 years old. Of the 601 children with positive VCA-IgM, 429 (71.4%) suffered from respiratory tract infection.

CONCLUSIONSEBV infection is very common in hospitalized children in Wuhan. Respiratory tract infection is a leading disease in children with positive EBV antibodies. The infection rate of EBV in different age groups is different.

OBJECTIVETo observe the effect of SHENG MAI ZHUSHEYE on the movement parameters and viability of human sperm in vitro.

METHODSWe collected sperm samples from 33 normal fertile men, divided each into two, and cultured them in vitro with SHENG MAI ZHUSHEYE + Hams-F10 and Hams-F10 alone, respectively. Then we measured the straight line velocity (VSL), curvilinear velocity (VCL), average path velocity (VAP) and the amplitude of lateral head displacement (ALH) of the sperm by computer-aided semen analysis at 0.5, 1, 2, 4, 8 and 12 h. And the sperm viability was detected.

RESULTSVCL was significantly higher at 8 h (P < 0.05) and very significantly higher at 12 h (P < 0.01) in the SHENG MAI ZHUSHEYE + Hams-F10 group than in the Hams-F10 group. VSL, VAP and ALH were significantly increased in the former group at 4, 8 and 12 h as compared with the latter (P < 0.05). The sperm viability was significantly decreased in the Hams-F10 group at 12 h (P < 0.05).

CONCLUSIONSHENG MAI ZHUSHEYE can improve sperm movement parameters and increase sperm viability in vitro.

Objective To investigate the value of electrical impedance tomography (EIT) system in the early diagnosis of subarachnoid hemorrhage (SAH) through observing the primary regularity of the electrical impedance changes in SAH animal models as well as the possible mechanism of this regularity. Methods The experimental SAH models in piglets were intmduced by one-time injection of fresh autologous blood into the cisterna magna. We observed the changes of the two-dimensional imaging with EIT system used for cominual dynamic monitoring to the models.Results The models were successfully introduced in 8 piglets.In the forepan of the injection,resistivity configuration decreased at the anterior region of the head as well as the posterior of that. At the time of finishing injection,the resistivity configuration reached the negative max value.After injection,resistivity configuration at the anterior region of the head gradually came back. But the resistivity configuration at the posterior region of the head increased persistenny. Conclusions Althouth the configuration of human head is so complex that limits the application of EIT on the head,it does have certain sensitivity in the diagnosis of SAH and can localize the hemorrhage site, so EIT may be applied widely in early diagnosis and assistant treatment of SAH in clinical.

According to the knowledge gained from engineering of nisinZ, using plasmid pHJ201 DNA as template, NisinZ was mutated by site-directed mutagenesis, NisinZ mutant T8S contains Serine at position 8 instead of Threonine, NisinZ mutant N27K/H31K contains Lysine at position 27 and 31, respectively, instead of Asparagine and Histidine and NisinZ mutant T2S/ H31K contains dehydrobutyrine and Lysine at position 2 and 31 instead of dehydroalanine and Histidine. They are cloned into pMG36e and expressed in L. Lactis NZ9800, the expression products of these mutants purified by Sephadex CM-25 and Sephadex G-25 chromatography, some properties of NisinZ mutants (T8S, T2S/H31K and N27K/H31K) were studied. The results showed that the spectrum of antimicrobial activity and solubility of these mutants had not been changed, their antimicrobial activities were found to be slightly lower than that of the wild-type NisinZ. but mutants T8S and T2S/H31K showed higher stability, which were significantly more stable than wild-type NisinZ at 55 approximately 100 degrees C and pH7 approximately 9.
