Peripheral iridotomy using combination of semiconductor laser 532 and YAG laser was performed on 35 eyes of 29 patients. All procedures were performed successfully and there was no significant change in visual acuity after treatment. One week after treatment, the intraocular pressure was 6.99 - 20.08 mm Hg(0.93 -2.67 kPa). Peripheral anterior chamber angles were all widened, no acceleration of lens opacity was observed. Combination of semiconductor laser and YAG laser peripheral iridotomy are safe and effective for angle closure treatment and can be performed in community hospitals.

Objective To explore the efficacy of ligustrazine combined with chemotherapy in patients with relapsed or refractory NHL and the relationships with P-gp expression. Methods 60 Patients were randomized into reversal agent group (ligustrazine + chemotherapy) and control group (chemotherapy) and the outcome was analysed. P- gp expression was analysed by flow cytometry. Subgroup analysis was conducted a ccording to P-gp expression. Results 56 patients could be evaluated. Progression -free survival (PFS) showed no statistical diference in two groups ( P = 0.065 1 ) ; reversal agent group had a higher overall response rate (ORR) than control group(P=0. 048).Subgroup analysis showed 41 patients had P-gp( +). The complete remission rate and complete remission uncertain rate of patients with P-gp( + ) in reversal agent group and control group were 33. 33% and 8. 70% , respectively, reversal agent group had a significant advantage ( P = 0. 048). Patients with P-gp( + ) in reversal agent group had a higher ORR than control group (61. 11% vs 26. 09% ,P =0.024). Kaplan-Meier survival curve and Log-rank test showed patients with P-gp( + ) in reversal agent group had longer PFS than control group (P =0.046 4). Blood pressure in a small number of patients received ligustrazine therapy decreased,and mitigated after reducing the dose. Conclusion Ligustrazine combined with chemotherapy can elevate response rate,prolong PFS with manageable toxicity and correlate to P-gp expression in relapsed or refractory NHL

Objective To study the effects of preoperative psychological state on calm time、recovery time and the level of pain about female tumer patients with general anesthesia.Methods We selected 105 female tumer patients whose ages were from 39 years to 66 years.They were divided into two groups according to SAS grade.We observed the calm time,recovery time and the VAS about the two groups.Results The calm time and reeovery time in disquieting group was significant longer than that of the normal group.There was a significant difference between group A and group B(P＜0.01).Otherwise the grade of VAS after operation was significant greater than that of the normal group.Conclusion The disquieting preoperative psychological state would effect the results of general anesthesia.The anesthetist should pay attention to the visiting patients before operation.

Objective:To investigate the role of clinical pharmacists in the therapy for a patient with acute promyelocytic leukemi-a. Methods:Clinical pharmacists participated in the treatment process of a patient with acute promyelocytic leukemia complicated with retinoic acid syndrome after tretinoin therapy. The rational treatment plan was put forward according to the literatures,the characteristics of drugs and the general situation of the patient. Results: Promising therapeutic effect was obtained,and the patient was discharged from the hospital. Conclusion:Clinical pharmacists play an active role in improving rational drug use and providing better individual-ized treatment for patients.

Intracranial germ cell tumors (IGGCTs) are rare intracranial embryonal tumors with various histological types. Most types of germ cell tumors are sensitive to radiotherapy and chemotherapy and can be cured with early treatment. The 5-year overall survival rate (OSR) of people with IGGCT has been reported as high as 90%, while the 5-year OSR of other malignant non-germinomatous germ cell tumors (NGGCTs) has been reported as less than 70%. Due to developments in surgery, imaging, nuclear medicine, pharmaceuticals, and other disciplines, the therapeutic effect of IGGCTs has improved in the last decade. However, due to the slow progress in researching its pathological genes, a treatment plan has not been standardized, and there is no standardized and clear clinical pathway or diagnosis and treatment guide. Here, the treatment experience and progress of IGGCTs is reviewed.

AIM:To establish the quality standard of the composition of Yuquan Micropill(Radix Rehmanniae,Fructus Schisandrae Chinensis,Radix Puerariae lobatae,etc.). METHODS: The composition of Yuquan Micropill were identified by TLC and the content was determined by HPLC.Puerarin could be separated through Diamonsil~(TM) C_(18) column(5 ?m,250 mm?4.6 mm) with methanol-water(1.2∶3 by volume) as a mobile phase.The flow rate was 1.0 mL/min,the detection wavelength was set at 250 nm and the column temperature was maintained at 40 ℃.?-Schizandrin could be separated through Kromasil KR100-3.5 C_(18) column(100 mm?4.6 mm) with methanol-water(3.5∶1 by volume) as a mobile phase.The flow rate was 0.6 mL/min and the detection wavelength was set at 254 nm. RESULTS: The spots in the TLC were clear and could be well separated,the blank and adjuvant contrast could not be interfered.HPLC showed a good peak form,good resolution and could not be interfered by the foreign matter.The average recovery of puerarin was 99.24%,RSD=0.84%,RSD of precision was 0.95%,RSD of reproducibility was 0.86%,RSD of stability was 0.44%.The average recovery of ?-schizandrin was 99.74%,RSD=0.78%,RSD of precision was 1.89%,RSD of reproducibility was 1.76%,RSD of stability was 1.82%. CONCLUSION: The method is simple and has good resolution,strong specificity and good reproducibility,It can be used for the quality control of the composition of Yuquan Micropill.

Objective:To investigate the role of sanchi Saponin Rg1 in D-galactose -induced amnesic mice ,and its possible mechanism.Methods:D-galactose was injected by subcutaneous to establish the aging model, and with drug treatment group.The Y-maze tests was performed to evaluate the learning and memory function, spectrophotometry was used to measure abilities of anti-oxidation.ELISA was adopted to evaluate the level of IL-1? and IL-6. Then FCM was applied to assay the index of intracellular calcium and the percentage of neural cell apoptosis.Results:Compared with drug treatment group, the model mice reduced significantly activites of anti -oxidation , the overload of intracelluer calcium and the increase in apoptosis of neural cells as well as the inflammation factor.Conclusion:Sanchi Saponin Rg1 decreased in the content of inflammation factor , the index of intracellular calcium and the percentage of apoptosis in neural cells , possibly by enchancing the antioxidant function.

Allergy increasingly threatens human health. At present, the molecular mechanisms of allergy have been one of the hot topics. It is believed that genetic factor and environmental factor play important roles in allergy. It is not surprising that particular HLA (human leukocyte antigen) class II alleles have been implicated in susceptility to allergic diseases and in restriction of the IgE responses to a variety of allergens. It will provide an original measure if the correlation between allergy and HLA genetic polymorphism was illuminated.

Aim To explore the correlation of positive specific IgE antibodies with penicillin allergy and HLA-DRB genetic polymorphism.Methods Sequence specific primer-polymerase chain reaction(PCR-SSP) was used to type human leucocyte antigen-DBR(HLA-DRB) alleles in 80 patients with positive IgE antibodies to penicillin and 101 healthy subjects without any allergic reactions.Results When different penicillin antigens were analyzed separately,the gene frequencies of DR16 in patients with positive BPO-IgE antibody and DR14.1 in patients with positive PVO-IgE antibody were found greatly lower than those of the control subjects(0 vs 8.62%,P

Pancreatic cancer is one of the most malignant tumors.Targeted therapy has become an important part of the treatment of pancreatic cancer.The signaling pathways such as hepatocyte growth factor/c-MET (HGF/c-MET) signaling pathway, inhibition of which may exerts an antitumor effect, play extremely important roles in the occurrence and development of pancreatic cancer.Therefore, the research of HGF/c-MET targeted inhibitors opens up a new avenue for treatment of pancreatic cancer.
