Chinese Journal of Primary Medicine and Pharmacy 2015;(16):2473-2474,2475
Objective To analyze the lipid levels in liver damage.Methods 82 patients with liver damage were divided into the study group(41 patients)and control group(41 patients),the control group patients were given treatment of atorvastatin,while the study group patients were given treatment of Zhibitai,the lipid metabolism of the two groups were compared.Results In the study group,levels of TC (5.16 ±0.8)mmol/L,TG(1.90 ±0.08)mmol/L,LDL(2.03 ±0.11)mmol/L were significantly lower than before treatment TC(5.82 ±1.26)mmol/L (t =4.38, P <0.05),TG(2.16 ±0.85)mmol/L (t =6.37,P <0.05),LDL(3.67 ±0.09)mmol/L (t =6.42).The HDL level (1.39 ±0.26)mmol/L was significantly increased (0.86 ±0.21)mmol/L (t =7.52,P <0.05)after 4 weeks treat-ment(P <0.05).The incidence of adverse events in the study group (7.3%)was significantly lower than the control group (17.1%)(P <0.05).Conclusion Zhibitai is safe and effective with use value in the treatment of liver dys-function.
2.Suprachoroidal space drug delivery C
Chinese Journal of Ocular Fundus Diseases 2017;33(2):209-213
The suprachoroidal space (SCS) is the potential space between the sclera and choroid.Drugs delivered through SCS can bypass the sclera,avoiding clearance by conjunctival and scleral blood vessels and lymphatic circulation,so that more drugs can reach the disease tissues such as choroid and retina.SCS drug delivery does not disrupt the ocular integrity,is safer than the intravitreal drug injection and more effective than trans-scleral drug delivery.In addition,SCS delivery only needs a very small volume of drug,which makes it possible to be carried out in multiple parts of the sclera,and the specific disease area can be more precisely targeted.SCS drug delivery is suitable for the treatment of choroidal and retinal diseases.However,currently SCS drug delivery is still a novel field and many aspects need to be more in-depth studied,including its safety,delivery methods,drug formulation and effectiveness.

Objective:The main purpose of this research is an experiment on the application of a comfort nursing model to a stem cell collection of peripheral blood procedure.Methods: The comparison method has been applied in this research. 178 cases have been selected as a whole research group. Then 88 cases are the observed group who will adopt the comfortable nursing model and 90 cases are the control group who will adopt the normal model.Results: The result of the comparison method shows that the observed group has lower mental pressure during the stem cell collection progress. Furthermore, the satisfaction feedback of the observed group is 90.9% but the control group is 67.8%.Conclusion: This research found that the application of the comfortable nursing modeling in stem cell collection of peripheral blood will ensure the collection process is completed smoothly. More importantly, an improvement was made in medical treatment quality and patient satisfaction.

AIM: To establish a method for the determination of Astragaloside Ⅳ in Oiluyishen Tabletes(Radix Astragali, Herba Pyrolae, Rhizoma Atractylodis Macrocephalae, Poria, Radix Codonopsis,etc.) by HPLC-ELSD. METHODS: Chromatography was performed on a 5?m HIQsilC 18 column(4.6mm?250mm) at 25℃. The mobile phase composition was acetonitrile-water(34∶66). The flow rate was at 1.0mL?min -1. An evaporation light-scattering detector (ELSD) was used as detector with gas flow rate of 2.6 mL?min -1 and drift tube temperature at 100℃. RESULTS: The linear range of Astragaloside Ⅳ was in the range of 2.288~ 22.88?g, r=0.999, the average recovery was 98.8% and RSD was 1.2%. CONCLUSION: This method is simple, feasible and reproducible. It can be used for the quality control of Oiluyishen Tabletes.

Objective To investigate the expressions of cell phenotypes CD_8 and CD_(28) of peripheral blood lymphocytes in patients with colorectal cancer. Method CD_8 and CD_(28) of cell phenotypes were measured by flow cytometry in 50 patients with colorectal cancer (cancer group) and 30 nontumorous patients (control group). Results The expression of CD_8 in cancer group was significantly higher than that in control group [(32.24±8.38)% vs (22.18±7.55)%](P < 0.01). CD_(28) and CD_8~+/CD_(28)~+ were much lower than those in control group [(52.03±10.94)% vs (60.60±7.98)%,12.18±4.28 vs 16.38±4.94](P<0.01). CD_8~+/CD_(28)~+ in Dukes D stage patients were significantly lower than that in Dukes B stage patients (P<0.05). CD_(28) and CD_8~+/CD_(28)~+ in lymph node metastasis patients were much lower than those in lymph node negative patients (P < 0.01). CD_(28) and CD_8~+/CD_(28)~+ in serosa involved patients were lower than those in no serosa involved patients (P < 0.01). Conclusions The expressions of cell phenotypes CD_8 and CD_(28) of peripheral blood lymphocytes in patients with colorectal cancer are closely related to biological characteristics of the tumor. The assays of cell phenotypes CD_8 and CD_(28) might be useful for evaluating the immunal statement and prognosis of patients with colorectal cancer.

Objective To understand the causes and the ratio of cause constituents in children with chronic cough in Beijing. Methods Patients with chronic cough treated at respiratory clinic of the Children' s Hospital Affiliated to Capital Institute of Pediatrics from May 2009 to April 2011 were included in this study. Etiologic diagnostic procedure suggested for children by the Subspecialty Group of Respiratory Diseases,the Society of Pediatrics,Chinese Medical Association in 2008 was implemented to manage the patients. After three - month follow - up,the etiological data was analyzed. Results Totally 213 patients with chronic cough aged 1. 1 to 14. 0 years old were enrolled,inclu-ding 40 cases(18. 8% )aged≤3 years old,134 cases(62. 9% )aged ﹥ 3 to 6 years old,and 39 cases(18. 3% ) aged ﹥ 6 years old. The majority of patients with positive allergen tests were sensitized to inhaled allergens. One child had positive result in 24 - hour esophageal pH monitoring,but his cough didn't respond well to the specific treatment for gastroesophageal reflux,so he wasn't diagnosed as gastroesophageal reflux cough. The 4 leading causes of the 213 pa-tients with chronic cough were cough variant asthma(CVA)in 92 cases(43. 2% ),CVA associated with upper airway cough syndrome(UACS)in 57 cases(26. 8% ),UACS in 28 cases(13. 2% ),respiratory infection and post - infec-tion cough(PIC)in 26 cases(12. 2% ),while other causes were found in 8 cases(3. 7% ),and unknown etiology in 2 cases(0. 9% ). The incidence of CVA ranked top 1 in all the 3 age groups,followed by PIC in ≤3 years old group, while CVA associated with UACS in the other 2 age groups. Conclusions CVA,CVA associated with UACS,UACS and PIC were the 4 leading causes for children with chronic cough in Beijing. Children in different age groups had dif-ferent constituents ratio of causes of chronic cough.
