Objective To study the effect of shenfu injection on the neuron apoptosis in hippocampal CA1 region of newborn with hypoxic-ischemic brain damage(HIBD).Methods The experiment included 2 parts.One was to measure the apoptosis rate by the flow cytometry,and the other was to investigate the expression of Bcl-2 and Bax of neurons in left hippocampal CA1 region.Models of postnatal 7-day Sprague-Dawley(SD)rats with HIBD were established,and were equally divided into 4 groups:sham operation(group S),control group(group C),shenfu injection pretreatment(group P),and shenfu injection treatment(group SF).The neuron apoptosis rate in hippocampal CA1 region in every group was measured at 2 h before and 2,12,24 h,3,7,14 and 28 d after hypoxic ischemic(HI) insult.The expressions of Bcl-2 and Bax were performed by immunohisochemistry.Results The apoptosis of neuron in hippocampal CA1 region in group P and group SF after HI insult was significantly less than that of group C(P

Chinese traditional medicine has provided, since ancient times, a basis for health care and medicine to the Chinese nation and for China's national stability. Identification of the constituents responsible for therapeutic and undesired effects of Chinese herbal medicines is a type of key research facilitating the modernization of these medicines. For a complex Chinese herbal medicine, multi-compound pharmacokinetic research is a useful approach to identifying its constituents that are bioavailable (in their unchanged and/or metabolized forms) at loci responsible for the medicine's therapeutic action and to characterizing the compounds' disposition and pharmacokinetics related to the action. In addition, such pharmacokinetic research is also useful for identifying herbal compounds associated with the medicine's adverse effects and drug-drug interaction potential. Over the past decade, great advances have been achieved in the theory, methodology, associated techniques, and their application of such multi-compound pharmacokinetic research, which has become an emerging field in pharmacokinetics. In this perspective, we elaborate on the methodology, technical requirements, and key analytical techniques of multi-compound pharmacokinetic research on Chinese herbal medicines, describe research examples regarding investigation of pharmacokinetics and disposition of a class of bioactive herbal constituents (ginsenosides of

Objective To evaluate the effects of active cycle of breathing techniques (ACBT) on respiratory complications of postoperative lung cancer patients. Methods One hundred non-small-cell lung cancer patients who underwent pulmonary lobectomy or segmentectomy in thoracic surgery department from April 2012 to January 2014 were assigned into the control group , while the experiment group were paired patients from February 2014 to December 2014. We applied ACBT to the experiment group for 5 days after surgical resection and afterward compared the two groups in view of incidence of respiratory complications . Result The incidences of pulmonary infection, atelectasis and hypoxemia in the experiment group were all significantly lower than those in control group (P<0.05). Conclusion ACBT strengthens endurance and force of patients′respiratory muscle group, and therefore reduces postoperative pulmonary complications.

Objective To investigate the effects of the folic acid on human T lymphoid leukemia cell line CEM cells. Methods 1. MTT method was used to detect the proliferation of CEM cells co- cultured with folic acid of different concentrations and time;2. E-xamine the changes of morphology by light microscopy with Giemsa stain;3. Detect the percentage of apoptosis and cell cycle distribution as well as the expression of the apoptosis protein(Bcl- 2,C- myc) by flow cytometry;4. Detect DNA fragments by Agaiose elec-trophoresis;5. Detect the influence of folic acid to the anticancer effects of methotrexatc(MTX) by MTT methods. Results 1 Folic acid could inhibit the proliferation of CEM cells, and the optimal inhibitive concentrations range from 0. 4 ? 10-4 ?g/L to 3. 0 ? 10 -4 ?g/L,the inhibition rate was about 30% - 40% ; 2. Co - cultured with folic acid at 24,48, 72 hours, examined by light microscopy with Giemsa stain, apoptosis cells were found in all study groups but the higher apoptosis rate was found co - cultured with folic acid at concentration of (0.4 - 3.0) ? 10-4?g/L;3.The highest apoptosis rate was 6. 19% found at the concentration of 3 ? 10-4 ?g/L, but the cell cycle distribution had no statistical difference with control group, the expression of apoptosis related protein Bcl - 2 and C-myc was decreased;4 DNA was extracted from CEM cells co - cultured with 0.4? 10 -4 ?g/L and 3 ? 10-4 ?g/L folic acid for 48 hours. UNA ladders were visible by agarose electrophoresis of DNA fragments; 5. Folic acid did not affect the antitumor effect of MTX at the concentration from 0 2? 10-4 ?g/L to 12.0?10-4 ?g/L. Conclusion Folic acid may suppress proliferation and induce apoptosis of CEM cell

Objective To analyze the antimicrobial susceptibility of Mycoplasma isolates for rational antimicrobial therapy. Methods BioM?rieux IST kit was used for identification and susceptibility testing of Mycoplasma strains.Results Mycoplasma was positive in 49.5% of the specimens tested.Of the Mycoplasma detected,Ureaplasma urealyticum(Uu)alone accounted for 74.7%,Mycoplasma huminis(Mh)alone accounted for 18.1%,and Uu+Mh was identified in 7.2% of the patients.The results of antimicrobial susceptibility testing showed that the Mycoplasma isolates were most susceptible to doxycycline (98.1%).Ciprofloxacin was the least active (17.3%).Conclusions Doxyeycline,josamycin,and clarithromycin can be used in the treatment of urinary tract infections caused by Mycoplasma.

Objective To compare the curative effect of high ligation+exfoliation and subfascial endoscopic perforator surgery(SEPS)for superficial varicose veins in calf+invagination spot-striping surgery in great venous varicosity.Methods Study group(42 patients)accepted SEPS+invagination spot-striping surgery and control group (42 patients)accepted traditional surgeries.Operation duration,bleeding volume in operation,the time of beginning movement away from bed after operation,hospitalization duration,the degree of pain,the scar,the recrudescence af- ter operation and the instance of the ulcer heals of two groups were compared.Results Operation duration,bleeding volume in operation,the time of begin movement away from bed after operation and hospitalization durations of study group were significantly lower than those of control group(P0.05).All of the patients in study group recovered without severe syndromes such as venous thrombosis,skin necrosis,lower limb functional disorder etc.They had no recrudesce after 4~16 months and were satisfied with the curative effect.Con- elusions The clinical curative effect of SEPS+invagination spot-striping surgery in great venous varicosity is superi- or to that of traditional operation and it has the advantages such as minor wound,few scars,light pains,short hospi- talization duration,without recrudescence,the ulcer heals quickly and so on.
