Objective:To evaluate the clinical effects of clindamycin injection on respiratory tract infections. 　Methods:Clindamycin injection was used in 50 respiratary tract infections patients aged over 18 years by intravenous drip with a dosage of 1.2 g once a day for a consecutive of 10 days. The symptoms and signs of the patients were observed, and the laboratory tests made.　Results: The numbers of patients who were cured, remarkably improved, improved and without any improvement were 25, 19, 5 and 1, respectively. The total effectiveness rate was 98.0%.　Conclusion: Clindamycin injection is significantly effective for treating the mild to moderate respiratory tract infections, especially for those caused by haemolytic streptococcus, streptococcus pneumoniae and lamellar bacillus. It has very little and mild side effects and is suitable for those allergic to penicillin.

Objective To observe the effects of restrain stress on the phosphorylation of p38 mitogen-activated protein kinase ~MAPK) in rat hypothalamus and the regulation effects of electroacupuncture on the phosphorylated-p38 MAPK. Methods Twenty-eight rats were randomly divided into a control group, a restrain stress group and a restrain stress plus electroacupuncture group. The Western blot was employed to observe the changes of phosphorylated-p38MAPK in the three groups. Results Western blot analysis demonstrated a higher level of phosphorylation of p38 MAPK in the hypothalamus from restrain stress group than that from control. The higher level of phosphorylated-p38 MAPK could last for 3 hours after stress was relieved. The level of phosphorylated-p38MAPK could be decreased to some extent when the Zusanli acupoint of the restrained rat was acupunctured. The effects of electroacupuncture of Zusanli on phosphorylated-p38MAPK in hypothalamus could still be retained although the electroacupuncture was ended for 3 hours. Conclusion The results suggested that restrain stress can lead to a higher level of phosphorylation of p38 MAPK in hypothalamus, which might be an important event in the response of hypothalamic-pitutary-adrenal ~HPA) axis. The mechanism underlying the regulation of HPA by electroacupuncture might be (related) to the regulation of phosphorylated-p38 MAPK in hypothalamus.

Objective To review the efficacy and safety of brucea javanica oil in the adjuvant therapy of primary hepatocellular carcinoma (HCC).Methods China National Knowledge Infrastructure (CNKI),China Biology Medicine (CBM),VIP,Wanfang database,Pubmed,Web of Science,ScienceDirect,and Cochrane Library were searched from their inception to December 2015.Then contact with the field experts and correspondence authors for gray literature.Two reviewers independently searched the databases,performed data extraction,and appraised the publications.The Reviewer Manager 5.3 software was employed for data analysis.Results Fifteen clinical trials with 1 128 HCC patients were included.Meta-analysis confirmed that the brucea javanica oil group,compared to the control group,was more advantageous to reduce the incidence of postoperative fever,bone marrow suppression,and gastrointestinal reaction.In addition,it might reduce the level of alpha fetoprotein (AFP),enhance immunity,and improve clinical symptoms.However,more evidence would be needed to support these results.Conclusions Brucea javanica oil is considered to reduce toxicity and increase efficiency in the adjuvant therapy for the HCC,but more high quality,multi-center,large sample,randomized,double-blind clinical trials are also needed for supporting this view.

Ramie and kenaf were traditional fiber crops in China, but their stalk after decorticating has not been used effectively. The stalk contains a lot of cellulose, and can therefore be used for the production of bioethanol. We studied the effects of different chemical pretreatment on enzymatic digestibility of ramie stalk and kenaf stalk. Ramie and kenaf stalks pretreated with alkali were chosen to produce ethanol using quasi-simultaneous saccharification and fermentation (Q-SSF) process. The results show that for the stalks pretreated with 4% NaOH and 0.02% anthraquinone-2-sulfonic acid sodium salt (AQSS) as catalyzer at 170 degrees C for 1 h, the ethanol concentration could reach 51 g/L after fermentation for 168 h at 18% of solid substrate concentration. By fed-batch to 20% of solid substrate concentration, the ethanol concentration could reach 63 g/L, 77% and 79% of the cellulose conversion could get for ramie stalk and kenaf stalk, respectively. For kenaf stalk pretreated with 5.2% NaHSO3 and 0.2% H2SO4 at 170 degrees C for 1 h, the ethanol concentration and cellulose conversion could reach to 65 g/L and 72%, respectively.

Objective To observe the changes in cerebral microcirculation after subarachnoid hemorrhage(SAH) and to study its correlation with cerebral vasospasm(CVS).Methods Eighty-five SAH patients and 35 controls,enrolled in this study as perspective study subjects,were divided into SAH group and control group,CVS group and non-CVS group(nCVS),symptomatic CVS(sCVS) group and asymptomatic CVS(asCVS) group.All the subjects underwent CT perfusion(CTP) and the associated parameters,including cerebral blood flow(CBF),cerebral blood volume(CBV) and mean transit time(MTT),were recorded for final analysis.Results Compared to the control group,the CBF and MTT were significantly changed in SAH group(P

Objective To compare the effect of Buzhong Yiqi Decoction (BYD) containing different doses of Radix Astragali on fibulin-3 expression in the hemorrhoid tissues of stage Ⅲ internal hemorrhoids patients with spleen deficiency and sinking of qi, and to evaluate its therapeutic efficacy and possible mechanism. Methods Fifty-five qualified patients were randomly divided into control group(N = 15), Chinese medicine group 1(N =20), and Chinese medicine group 2(N=20). All of the 3 groups were treated with operation, and additionally, Chinese medicine group 1 was given BYD containing Radix Astragali 20 g, and Chinese medicine group 2 was given BYD containing Radix Astragali 50 g orally after operation. The scores of anal pendant expansion and anal prolapse were evaluated, and the expression level of fibulin-3 in the hemorrhoid tissues was detected by Western blot method. Results After treatment, the symptoms of anal pendant expansion and anal prolapse were improved in the 2 Chinese medicine groups (P < 0.05) , and the improvement of anal pendant expansion symptom in Chinese medicine group 2 was superior to that of Chinese medicine group 1(P<0.05). Compared with the control group, the expression level of fibulin-3 in the hemorrhoid tissues of the two Chinese medicine groups was increased (P < 0.05); the expression level of Chinese medicine group 2 showed an increasing trend as compared with that of Chinese medicine group 1, but the difference was statistically insignificant (P > 0.05). Conclusion BYD with large dose of Radix Astragali exerts stronger therapeutic efficacy for the treatment of prolapsed hemorrhoids than BYD with small dose of Radix Astragali, and its therapeutic mechanism has no obvious relation with promoting the increase of fibulin-3 expression.

Objective To evaluate the utility of flow cytometry (FCM) in diagnosis and subclassification of non-Hodgkin lymphoma (NHL). Methods The samples of lymph nodes biopsy from 59 cases clinically suspected of NHL were detected by flow cytometry; and clonal lymphocytes and their immunophenotypes were identified analyzed. The concordance between the results of flow cytometry and histopathology was analyzed. Results Among the 59 cases, flow cytometry was able to identify aberrant clonal lymphocytes in 24 of 28 NHL cases identified by histopathology, the neoplastic lymphocytes ranged from 4.28 % to 89.10 %; 23 cases were diagnosed as B-NHL and 1 case was diagnosed as T-NHL. Compared with histopathology, the accuracy of FCM was 85.71% in diagnosis of NHL. The specificity and sensitivity of FCM was 100 % and 92% in diagnosis of B-NHL. The accuracy of flow cytometry immunophenotyping in classification of 24 cases of NHL was consistent with that of histopathology. Conclusion Flow cytometry could be an ancillary technique in diagnosis of NHL by identifying aberrant clonal lymphocytes, and enable identification of B-NHL subtype.
