Objective To investigate the effect of milk basic protein (MBP) on bone metabolism in normal and ovariectomized (Ovx) rats. Method Forty-eight female Sprague-Dawley rats were ovariectomized and another 12 rats received sham operation (Sham). After 10 d recovery period, the Ovx rats were randomly divided into 4 groups: control, low-dose, medium-dose, and high-dose MBP group. Another 44 normal female rats without ovariectomy were also divided into 4 groups as above. The MBP dosages for each group were respectively 0, 10, 20, 30 mg/kg bw. All rats were i.g. administered for 90 d. Bone mineral density (BMD) of the femur (at proximal end, middle of diaphysis, and distal end) was measured by dual-energy X-ray absorptiometry in vivo. The amounts of calcium, magnesium and phosphorus were analyzed by ICP-AES. Results BMD at distal end of femur was significantly higher in normal low-dose group than in normal control group while no significant effect was observed in Ovx MBP groups. As for the amounts of calcium, magnesium and phosphorus, there were no significant differences among normal experimental groups and also among Ovx experimental groups. However, some variations in the level of those minerals were observed. Conclusion MBP at 10 mg/kg bw significantly elevated BMD at femoral distal end in normal rats, while no similar effect was observed in Ovx rats. Besides its influence on bone minerals, there may be another mechanism involved in its effect on bone metabolism.

Objective To determine platelet count (PLT),mean platelet volume (MPV),and hemodynamic changes in patients with cir-rhotic portal hypertension (CPH)post splenectomy plus pericardial devascularization (SPPD),and to assess the surgical effect on coagula-tion function.Methods A retrospective analysis was performed on 83 CPH patients undergoing SPPD in our hospital from January 2008 to December 2012.Results Compared with preoperative levels,postoperative portal venous pressure decreased,blood flow was reduced,and portal vein diameter was significantly reduced;additionally,postoperative hepatic artery diameter was increased,and hepatic artery blood flow increased.Blood alanine aminotransferase,albumin,total protein,and fibrinogen levels,thrombin time,and MPV did not significantly change 30 days postoperatively versus 7 days preoperatively(P>0.05 );the corresponding total bilirubin,activated partial thromboplastin time and prothrombin time relatively declined(P<0.05),whereas PLT and prothrombin time activity increased(P<0.05).There was a significant increase in PLT (P<0.05)but no significant change in MPV 30 days postoperatively versus 7 days preoperatively (P>0.05). Conclusion SPPD can significantly improve liver functional reserve and coagulation function in patients with CPH.

Objective To study the effectiveness and toxicity of ifosfamide(IFO) combined with venorelbine(VRL) in patients with nasopharyngeal carcinoma(NPC) refractory to platinum based chemotherapy. Methods The chemotherapy protocol consisted of intravenous infusion of IFO at the dose of 1200 mg/m2 from day 1 to day 5 with uroprotection of Mesna in infusion at 0,3,6 hours following initiation of IFO and VRL at the dose of 25 mg/m2 at day 1 and day 5. The protocol was repeated every 3 weeks. All patients received at least 2 cycles of chemotherapy. Results Among 25 patients enrolled into the study, 2 patients achieved complete remission, 12 patients achieved partial remission with an total remission rate of 56.0 % and 8 patients had stable disease with clinical benefit rate of 88.0 %. 3 patients had disease progression. Median time to progression was 7.1 months(range:2.0～21.0 months) and 1-year survival rate was 55 %. The main toxicities were myelotoxicity and phlebitis. Conclusion The results indicate that IFO combined with VRL in patients with NPC refractory to platinum based chemotherapy has moderate activity ascompany with tolerable toxicities.

Objective To investigate the effect of EDTA combined with ciprofloxacin on Pseudomonas aeruginose biofilm in vivo.Methods Pseudomonas aeruginosa was inhaled into the lung of guinea pigs and colonized,formed biofilm.After 7 days,the model was treated with ciprofloxacin,EDTA alone,or a combination of both for 7 days.The number of colony in the lungs is measured by agar plate.The pathological change of the lung is observed by hematoxylin and eosin (HE) staining and scanning electron microscope.Results EDTA combined with ciprofloxacin make the number of bacteria in the lungs reduced from l05 CFU/g to 10 CFU/g(t =24.67,P＜0.05),the lung lesion was less-sever histophathologically.Conclusion The combination of EDTA with ciprofloxacin has significant activity to remove mucoid PA biofilm in vivo.

As an indispensable part of minority traditional medicine, mineral medicine has used with less dosage and reliable efficacy for the last thousand years. Based on the unearthed relics and medical literatures of past dynasties, the history of Han nationality ap- years, which had been recorded in main literature. But there is less comprehensive report of its usage in the other 55-minority nationality. This article was based on the analysis of ethnic minority literature of thousands of years, and conducted a comprehensive collation and analysis of mineral medicine. It was mostly determined that there was 20 minority groups using mineral medicine, with a total of 163 species (limited our references), and the most used is the Tibetan, accounting for 141. The most serious problems of mineral medicine are that species should be further investigated and researched, and then become the legal commercial medicine, and the classification principles of mineral medicine should be established. Through the traditional processing and experimental studies, the problems of attenuation and detoxification should be solved.

The ralationship between traditional Chinese medicine (TCM) and intestinal microecology is increasingly being given more and more attention. Combined with the devolopment of intestinal microecology disciplines, effects of TCM on regulation of intestinal microecology have been gradually explained. Both clinical studies and animal experiments have confirmed that TCM can maintain the balance of intestinal microecology and regulate the intestinal flora. The author arrangemented the documents related to Chinese herbal compound adjusting intestinal flora in the recent ten years, summarized that the Chinese herbal compound which can strength spleen and replenish Qi, relax bowels and regulate Qi, dissipate dampness and check diarrhea, clear away heat and toxic materials, promote digestion and relieve stasis had certain regulation effects on intestinal microecology, providing basis for revealing the TCM essence of intestinal microecology.

Objective·To investigate correlation of serum acute amyloid A (A-SAA) level and activity of Behcet's disease (BD).Methods·Blood samples from patients with active BD (n=40),remission BD (n=15),Takayasu disease (TA,n=12),rheumatoid arthritis (RA,n=25),systemic lupus erythematosus (SLE,n=25) and healthy donor (HD,n=25) were collected.Serum A-SAA,ESR,and CRP levels were detected and compared among groups.The correlation between A-SAA and its downstream IL-8 or International Society for Behcet's disease (ISBD) disease activity scores was analyzed as well.Results·Serum A-SAA level was significantly increased in the patients with active BD [(115.70±87.78) mg/L],as well as patients with RA and TA,which levels were (68.72±61.50) mg/L and (96.25±87.41) mg/L respectively,but remained unchanged in SLE patients.Moreover,serum A-SAA level was found correlated with ISBD score as well as IL-8 level.Conclusion·A-SAA can work as a detection index for evaluating BD activity.

Objective To make a systematic review of pressure ulcers risk factors in critically ill patients. Methods We systematically reviewed all articles related to the pressure ulcers risk factors in critically ill patients. The Cochrane Library, PubMed, EMBASE, Web of Science Core Collection, CNKI, WANFANG and SinoMed were searched to August 2016. Results In total, 13 eligible articles were included. These studies included 18, 184 critically ill patients, six studies were classified as high quality, and seven were classified as moderate quality. Risk factors for the development of pressure ulcers include age, ICU stay, diabetes, mean arterial pressure<60-70 mmHg (1 mmHg=0.133 kPa), mechanical ventilation and mechanical ventilation, drugs, sedation and postural changes. Conclusions There is no single factor that can explain the occurrence of pressure ulcers. So it is in a variety of factors interaction, the occurrence of a significant increase in risk.

To study the effects of tetrandrine (Tet) on hypertrophied myocardial hydroxyproline content and myosin ATPase activity, left ventricular hypertrophy(LVH) was induced by renovascular hypertension (two-kidney, one-clip) in rats. Eight weeks after operation Tet 50 mg*kg-1*d-1 and enalapril(Ena) 6 mg*kg-1*d-1 were given by gavage for 8 weeks. The results showed that hydroxyproline content in LVH group was much higher than that of sham-operated one 〔(5.9±0.3) vs (3.6±0.4) mg*g-1 dry weight〕, and was decreased by 28.2% and 39.0% in Tet and Ena groups, respectively. Myosin ATPase activity in LVH group was much lower than that of sham-operated group 〔(0.43±0.09) vs (0.97±0.06) mmol Pi*min-1*g-1 protein, P<0.01〕. In Tet and Ena groups they were 60.5% and 118.6% higher than that of LVH group, respectively. The results suggest that Tet or Ena partially reduce the hydroxyproline content and elevate myosin ATPase activity of hypertrophied myocardium in renovascular hypertensive rats.
