Retinoblastoma (RB) is the most common intraocular malignant tumor in children. With advanced clinical technologies there are more and more methods available to treat retinoblastoma, and make it is possible to delivery individualized protocol combined traditional treatments with modern regimen to patients now. In order to improve the survival rate and the life quality of RB patients in China, it is very important to make a suitable system of standardized therapy based on results from developed countries and health policies of our own country.

Objective To study the extraction process of Jiejiu Gankang granules by orthogonal test.Methods With the ethanol extraction rates of the medical materials like ginseng,radix salviae miltiorrhizae,the water extraction rates of the medical materials like hawthorn,and Tanshinone ⅡA as the parameters,the extract conditions of Jiejiu Gankang granules was optimized by orthogonal design.Results The optimal preparation process was as follows:the mixture of medical materials like ginseng and Schisandra chinensis was refluxed twice with total 10 times of 70% alcohol,2.0 hours for each time,and then the mixture of medical materials like hawthorn extracted twice with total 10 times of boiling water,2.0 hours for each time.Conclusion The optimal preparation process is reasonable and with high extraction rate of active components.

OBJECTIVETo explore different regulatory effects of electroacupuncture (EA) at the same acupoint on the heart and the stomach.

METHODSEighty male SD rats were randomly divided into eight groups equally, i.e., the Neiguan (PC6) group, the Quchi (LI11) group, the Tianshu (ST25) group, the Danzhong (RN17) group, the Zusanli (ST36) group, the Sanyinjiao (SP6) group, the Xinshu (BL15) group, and the Weishu (BL21) group, 10 in each group. The regulatory effects of EA (2/15 Hz, 3 mA, 2 min) at different acupoints on the gastric motility (intragastric pressure) and the cardiac function (the left ventricular pressure) were observed. The mean values of effect of two-min pre-EA and after-EA were compared.

RESULTSCompared with the pre-EA in the same group, the left ventricular pressure decreased in the Neiguan (PC6) group, the Quchi (LI11) group, the Danzhong (RN17) group, the Sanyinjiao (SP6) group, and the Xinshu (BL15) group (P <0.05). The intragastric pressure increased in the Quchi (LI11) group, the Zusanli (ST36) group, the Sanyinjiao (SP6) group, and the Xinshu (BL15) group, while it decreased in the Tianshu (ST25) group, the Danzhong (RN17) group, and the Weishu (BL21) group (P <0.05). The difference of the left ventricular pressure was sequenced from high to low as Xinshu (BL15) >Danzhong (RN17) >Neiguan (PC6) >Sanyinjiao (SP6) >Quchi (LI11). The difference of the intragastric pressure was sequenced from high to low as Tianshu (ST25) >Weishu (BL21) > Xinshu (BL15) > Danzhong (RN17) > Zusanli (ST36) > Sanyinjiao (SP6) > Quchi (LI11).

CONCLUSIONSEA at the same acupoint (2/15 Hz, 3 mA) showed different regulatory effects on the heart and stomach. There existed some difference in the direction and size due to the acupoint location, meridians, dominant nerve segment or relating organs. A fixed effect direction to the specific target was also shown.

As the necessary depletion material in hospitals,sterile packing material shows category diversification when being selected.This paper briefly analyzes the functions and values of domestic common sterile packing material such as pure cotton wrap cloth,hard quality packing container,paper/ plastics packing bag and the crease wrapping paper.Reasonable suggestions are also put forward.

OBJECTIVE:To establish a HPLC method for the determination of 5-fluorouracil in human plasma METHODS:The plasma samples were extracted with ethyl acetate-isopropanol(85∶15,V/V)following precipitation of plasma proteins with ammonium sulfate The solvent was evaporated to dryness under a stream of nitrogen The dry extract was dissolved in mobile phase and then injected into the Diamonsil C18 column(150mm?4 6mm,5?m)and 0 01mol/L KH2 PO4(pH5 5) was taken as mobile phase The flow rate was 1 5ml/min,UV detection wavelength was 267nm The internal standard was 5-bromouracil RESULTS:The minimal detectable drug concentration in plasma was 0 025?g/ml The calibration curve was linear over a range from 0 3?g/ml to 10?g/ml The intra-day RSD≤5 0%(n=5) and the inter-day RSD≤11 5%(n=5) CONCLUSION:The method can be used for studying the pharmacokinetics and bioavailability of 5-fluorouracil

BACKGROUND:It has been confirmed that carboxymethylated chitosan has an promoting effect on Schwann cel proliferation and secretion, but its impact on the cyclic adenosine monophosphate-mediated protein kinase A signaling pathway in schwann cel stil needs further study. OBJECTIVE:To investigate the effect of carboxymethylated chitosan on cyclic adenosine monophosphate/ protein kinase A signaling pathway in rat schwann cels. METHODS:The Schwann cels of the second generation neonatal rats were obtained and seeded in 6-wel plate at a concentration of 1×109/L. These Schwann cels were cultured and divided into four groups. The Schwann cels in the control group were cultured by adding PBS. The Schwann cels in the experimental groups were cultured by adding 50, 100 and 200 mg/L of carboxymethyl chitosan solution, respectively. After 24 hours, the concentration of cyclic adenosine monophosphate, protein kinase A activity and cyclic adenosine monophosphate response element binding protein mRNA expression were detected. RESULTS AND CONCLUSION:Compared with the control group, carboxymethyl chitosan increased cyclic adenosine monophosphate concentrations, the activity of protein kinase A and cyclic adenosine monophosphate response element binding protein mRNA expression within the Schwann cels in a dose-dependent manner (P < 0.05). These results demonstrate that carboxymethyl chitosan can increase the concentration of cyclic adenosine monophosphate within the Schwann cels and promote protein kinase A activity, thereby activating cyclic adenosine monophosphate/protein kinase A signaling pathway.

OBJECTIVETo explore the clinical effects of one-stage hemiarthroplasty in treating fresh subtrochanteric fracture combined with old femoral neck fracture.

METHODSFrom October 2003 to October 2013, 7 patients with fresh subtrochanteric fracture and old femoral neck fracture were treated with hemiarthroplasty in one stage. There were 5 males and 2 females, aged from 69 to 80 years old with an average of 74.5 years. According to the Garden classification, 2 cases were type IV and 5 cases were type V. According to the A0 classification of subtrochanteric fracture, all cases were type A1 (long oblique femoral subtrochanteric fractures). Biological coating long handle femoral prosthesis was used in the patients. The hip joint functions were assessed according to Charnley scoring system after all hemiarthroplasty.

RESULTSSeven patients were followed up from 12 to 24 months with an average of 18 months. There were 1 case with urinary system infection and 1 case with deep venous thrombosis. Of all, 5 cases recovered the walk ability at 6 months after operation and 2 cases could walk with the help of the crutch at 1 year after operation. According to Charnley scoring system to assess the hip joint function, the total Charnley scores reached 15.0±2.5, and 4 cases got an excellent results, 2 good, 1 fair.

CONCLUSIONArthroplasty through anterolateral approach can obtain satisfactory clinical effects in treating fresh subtrochanteric fracture combined with old femoral neck fracture, it has advantages of good joint stability, little pain, less complication, quickly recover, early activities on fields.
