Objective:To analyze Effect of laser combined with intravitreal administration of bevacizumab on patients with diabetic retinopathy.Methods: Chose 106 cases of diabetic retinopathy patients between June 2012 to June 2014 in our hospital as research object, according to stochastic indicator method divided into observation group (53cases) received laser combined with intravitreal administration treatment, control group(53cases) treated with bevacizumab administration alone,compared two groups of patients with visual acuity and retinal thickness,serum level of VEGF and Ang-2,serum levels of oxidative stress indicators.Results: 1)Observation group patients’ visual acuity level was obviously higher than that of control group, retinal thickness was significantly lower than control group(t=5.375,t=6.839;P<0.05); 2)Observation group patients serum VEGF and Ang-2 levels were significantly lower than control group(t=8.842, t=9.742;P<0.05); 3)Observation group patients adiponectin,superoxide dismutase(sod) levels were higher than control group, malondialdehyde level was lower than control group(t=7.382,t=8.276,t=6.093;P<0.05).Conclusion:Laser combined with intravitreal administration therapy can improve patients' eyesight, decrease thickness of retina, inhibit angiogenesis and optimize systemic oxidatie stress levels.

Objective: To estabalish the quality control standard for Yangyanan Lotion Fructus Cnidii; Herba Solidaginis; Cortex Phellodendri; Rhizoma Brainea insuignis. Methods: Fructus Cnidii , Herba Solidaginis, Cortex Phellodendri, Rhizoma Brainea insuignis were respectively identified by TLC. The cnidiadin in Yangyanan Lotion was purified by weak aqua ammonia and determined by HPLC.Results: The average recovery of cnidiadin was 97.96% ( n =6). with RSD was 2.2%.Conclusion: The identification was highly specific, and the method was simple, specific and accurate, and can effectively control quality of Yang Yunan Lotion.

Objective :To establish a RP-HPLC method for determination of isofraxidin in Pientzehuang oral tablet. Methods: RP-HPLC analysis was carried out on Nava-Pak C18 column and with acetonitrile: 0.1%phosphoric acid (15∶85) as a mobile phase. Results: The linear range was 12.9～90.3 ?g/mL(r=0.9999,n=7).The average recovery rate was 102.65 %and RSD=0.71 %.The intra-day and inter-day RSD was less than 3 %.Conclusion :This method is simple, rapid and accurate and suitable for the quality control of the preparations of Chinese herbal medicine containing isofraxidin.

OBJECTIVETo investigate the therapeutic effect of alar rotation flap for severe alar retraction.

METHODSPatients with severely retracted alar underwent ala reconstruction using alar rotation flaps and autogenous cartilage batten grafts. First, costal cartilage was used to reshape the nasal tip and nasal dorsum. Then cartilage patch was used to extend and thicken the retracted alar. Then the alar rotation flap was transferred to correct retracted alar.

RESULTSFourteen patients with severe alar retraction underwent alar reconstruction with alar rotation flap and alar batten grafts. The alar retraction was corrected in all cases, with improvements functionally and aesthetically. No recurrence of alar retraction was noted. The incision healed with acceptable cosmetic results, with obvious scar in only one patient (one side).

CONCLUSIONSThe alar rotation flap is an effective and reliable surgical option to correct severe alar retraction. Scar can be kept inconspicuous by precise placement of the incision within the junction of the ala and the nasal dorsum, following principles of the aesthetic nasal subunits.

Objective To analyze the clinical effect of nutritional support for postoperative patients with esophageal cancer with fat emulsion and amino acids (17) and glucose (11%) injection (Calvin injection). Methods A total of 68 patients with esophageal cancer treated in the chest surgery in our hospital from December 2014 to December 2016 were selected and randomly divided into two groups with 34 cases in each group. All patients were treated with surgery for esophageal cancer. The patients in the study group were treated with Calvin injection after operation while patients in the control group were treated with conventional fluid replacement therapy. Subjective comprehensive assessment (SGA) was used to assess the nutritional status of the patients and the weight, serum total protein (TSP), serum albumin (Alb), transferrin (TF) content, urea nitrogen content in on one week, malnutrition improvement and complications of the patients in two groups were recorded and compared. Results The weight of the patients with esophageal cancer in the two groups after operation was decreased, and the weight loss of the patients in the study group was lower than that of the control group and the difference was statistically significant (P<0.01). The decrease degree of TSP, Alb and TF in the study group was lower than that in the control group, and the difference was statistically significant (P<0.05). The negative nitrogen balance of the two groups was improved, and the improvement of the negative nitrogen balance in the study group was better than that in the control group, and the difference was statistically significant (P<0.01). The postoperative malnutrition in the patients with esophageal cancer was improved. The improvement degree of malnutrition in the study group was better than that in the control group, and the difference was statistically significant (P<0.05). The incidence of complications in the study group was lower than that in the control group, and the difference was statistically significant (P<0.05). Conclusion Compared with the traditional method of postoperative fluid replacement, Calvin injection can improve the recovery of the body function of the patients with esophageal cancer after operation, improve the patient's negative nitrogen balance and nutritional status, reduce the incidence of complications, and improve the clinical prognosis. This treatment is safer and more effective and it is worth popularizing in clinical practice.

Solid state fermentation involves the growth of microorganisms on moist solid substrates in the absence of free flowing water. It has gained considerable attention of late years due to its several advantages over submerged fermentation. This paper mainly introduces the characteristics and mathematical models of solid state fermentation and summarizes the development situation of various bioreactors, the design standards and applications.

OBJECTIVE:To establish a method for the bacterial endotoxin test of nicardipine hydrochloride glucose injection.METHODS:The bacterial endotoxin test was carried out according to the bacterial endotoxin test in the addenda of China Pharmacopeia 2005 edition(second part).RESULTS:Nicardipine hydrochloride glucose injection showed interference on the bacterial endotoxin test when water was taken as solvent.The preliminary interference test and interference test revealed that using thinnerⅠas solvent,the sample injection in over 4-fold dilution had no interference on the bacterial endotoxin test.CONCLUSIONS:It is feasible for bacterial endotoxin test of nicardipine hydrochloride glucose injection be conducted in a limit value of 0.5 EU?mL-1.The bacterial endotoxin text can substitute pyrogen test in the detection of nicardipine hydrochloride glucose injection.
