2.Staging syndrome differentiation and treatment of radiation pneumonitis
China Journal of Traditional Chinese Medicine and Pharmacy 2005;0(08):-
By staging radiation pneumonitis’ syndrome and discussing the pathogenesis, the course of radiation pneumonitis is divided into acute phase, lag phase and anaphase. Acute phase is treated with clearing heat and resolving phlegm, cooling ying and nourishing yin; lag phase is treated with supplementing qi and nourishing yin, promoting blood circulation and resolving phlegm; anaphase is treated with nourishing lung and strengthening kidneys, resolving stasis and dredging collaterals.

Objective To study anti-tumor effects on human ovarian cancer xenografted tumors in mice by constructing adenoviral expression vector containing canstatin gene and hTERT gene core promoter (AdhTERT-Can). Methods AdhTERT-Can vector was constructed and identified by means of enzyme cutting, electrophoresis and sequencing. Then, transfected into HO8910PM cells by means of lipofectamine and confirmed by green fluorescence protein(GFP) expression under laser confocus microscope. The mRNA expression of canstatin gene was tested by RT-PCR. Human ovarian cancer xenografted tumor models in nude mice were established and randomly divided into AdhTERT-Can group received viral supematant solution of AdhTERT-Can by tail vein injection, Ad-Can groups received viral supernatant solution of Ad-Can by tail vein injection, and control groups received phosphate buffer solution (PBS). The volume of tumors were measured and compared in each group to evaluated the anti-tumor efficacy. Results All the constructed vectors of AdhTERT-Can were verified by enzymed digestion. There were green fluorescence from 60% of HO8910PM cells transfected by AdhTERT-Can under laser confocus microscope, and the mRNA expression of canstafin gene in HO8910PM cells were also verified by RT-PCR The growth of tumor in AdhTERT-Can group was significantly inhibited compared with those in Ad-Can groups and control groups from the 8th day (P <0.01 ). However, there were not significant difference between Ad-Can group and PBS group (P> 0.05). On the 30th day, the tumors showed liquefaction necrosis and cystic degeneration in each group, especially in AdhTERT-Can group. Conclusions The recombinant adenovirus vector of AdhTERT-Can has been constructed successfully and could steady express in ovarian cancer cell lines HO8910PM. The results shown that it could inhibit significantly the growth of human ovarian cancer xenografted tumors in mice and shown to be the target of gene therapy.

Objective To observe the influence of desmopressin acetate (DDAVP) on blood loss and hemostatic function after cardiac surgery with extracorpoteal circulation.Methods Forty-one patients undergoing congenital heart operations, were randomly allocated to double--blindly receiving 0.3ug/kg DDAVP in a 50 ml saline(group DDAVP, n = 20) and 50ml normal saline (group placebo, n = 21) over 15 min after protamine infusion. Blood samples were obtained before operation, immediately before studied drug administration and 1 h after the administration, to measure the hematocrit, platelet count and aggregation, Factor Ⅷ coagulant activity and von Willebrand factor (vWF) concentration. Results The first postoperative 24-hour blood loss was significantly lower in group DDAVP than in group placebo [ (178 ? 90) ml vs (291 ? 98 ) ml, P 0 .05); The plasma level of vWF and factor Ⅷ coagulant activity markedly increased 1h after DDAVP administration as compared with those in group placebo, before operation and after protamine infusion in group DDAVP (P

This study examined the effect of MMP9 gene on the biological behaviors of trophoblasts and explore the relation between MMP9 gene and the "superficial implantation of placenta". In vitro cultured trophoblasts (TEV-1 cells) were transfected with synthesized double-stranded MMP9 RNA (siRNA) by using lipofectamine2000™ technique and the expressions of MMP9 mRNA and protein and the growth and invasiveness of the TEV-1 cells were determined. Our results showed that siRNA transfection could significantly inhibit the expression of MMP9 gene in the TEV-1 cells and the growth and invasiveness of the TEV-1 cells transfected RNA was significantly reduced (P<0.01). We are led to conclude that silencing of MMP9 gene with siRNA can inhibit the growth and invasiveness of trophoblasts and increasing the expression of MMP9 might help prevent and treat preeclampsia.

Objective To analyze the prevalence of hypertension in coal mine male workers and its influencing factors.
Methods A total of 1 772 coal mine male workers from a coal mining group were selected as research subjects using multi
stage
complex sampling method. The prevalence of hypertension and its influencing factors were analyzed. Results The
prevalence of hypertension was 33.0%(585/1 772). Logistic regression analysis of complex sampling showed that body mass
index, family history of hypertension, alcohol-drinking, tea-drinking, and snoring were independent risk factors for
hypertension(all P<0.05),after adjusting for the effects of other inclusion factors on the basis of age. The risk of hypertension
in coal mine male workers was higher in those with overweight and obesity than in normal weight(all P<0.01),higher in those
with family history of hypertension than in no history of hypertension(P<0.01),and higher in tea drinkers than in no tea
drinkers (P<0.05). The more the alcohol consumption and the higher the frequency of snoring,the higher the risk of
hypertension(all P<0.01). These factors have a dose-response relationship. Conclusion The body mass index,family history
of hypertension,alcohol-drinking,tea-drinking and snoring can affect the prevalence of hypertension in coal mine male workers.

Chinese herbal pieces are a key factor to protecting the quality of the clinical efficacy of traditional Chinese medicine (TCM), and it is one of the basic elements of ensuring the quality of TCM and people's usage safety. However, Chinese herbal pieces has massive problem such as adulteration and counterfeit, dyeing and weighting, pesticide residues, heavy metals in excess of the standards, and all the issues are repeated excessive in the clinic treatment. These issues impacted sound development of production, management and use of TCM, but also brings common people hidden trouble for the clinical safety of medication. Protect and improve the quality of the Chinese herbal pieces demand that continue improve quality system, in-depth scientific research, and strengthen self-discipline and other factors. So it is fundamentally to ensure good quality of Chinese herbal pieces with the color, taste and shape by systematic supervision to it from the source, production, management and research, with strengthened implementation and en- forcement of the "3G".
