Chinese Journal of Information on Traditional Chinese Medicine 2013;(10):49-50,51
Objective To explore the extraction and assaying of the alkaloids from Bozhou Peony Paeonia lactiflora. Methods Dry root powder of the medical material was extracted by 90%ethanol. The extraction was first acidified by hydrochloric acid after recovering alcohol, and then extracted by dichloromethane. The acid solution was adjusted pH to alkalescence by ammonia water, then extracted by chloroform to get crude alkaloid. Bozhou Peony alkaloids were confirmed by TLC along with different colouration method, and its content was detected by acid-base titration. Results Four alkaloid-representative salmon patches were observed by colored with improving potassium heptaiodobismuthate method, and two prunosus blotches, four dark prunosus spots were delected by concentrated sulfuric acid and formaldehyde-concentrated sulfuric acid method, respectively. However, no chromogenic spots were found by colored with nitric acid as well with ninhydrin. The content of alkaloids in Bozhou Peony Paeonia lactiflora was about 0.079%. Conclusion Bozhou Peony Paeonia lactiflora contained alkaloid, and may including aconitum alkaloids.

Chinese Journal of Biochemical Pharmaceutics 2016;36(4):86-88
Objective To investigate the efficacy of flupentixol and melitracen combined with pinaverium bromide in the treatment of patients with irritable bowel syndrome. Methods A total of 64 patients with irritable bowel syndrome from October 2014 to October 2015 in department of gastroenterology of Zhuji People’s Hospital were collected and randomly divided into two groups, with 32 cases in each group.Patients in control group received with pinaverium bromide by oral, patients in combination group received flupentixol and melitracen by oral on the basis of control group.The gastrointestinal symptom rating scale (GSRS), self-rating anxiety scale (SAS), self-rating depression scale (SDS) score and clinical efficacy pre-and post-treatment were compared between two groups.Results Compared with pre-treatment, the main symptoms score in two groups decreased significantly (P<0.05); compared with control group, the main symptoms score in combination group decreased significantly(P <0.05).Compared with pre-treatment, the SAS and SDS scores decreased significantly(P <0.05); compared with control group, the SAS and SDS scores in combination group decreased significantly ( P <0.05 ) .There was no significant difference in total efficacy between control group and combination group ( 93.75%vs.81.25%, χ2 =1.237,P=0.266).There was no adverse event in two groups during treatment.Conclusion Flupentixol and melitracen combined with pinaverium bromide could significantly improve the anxiety and depression in the treatment of irritable bowel syndrome, which could promote the recovery of gastrointestinal function.

Objective To explore the efficacy and safety of conversion from calcineurin inhibitor (CNI) to sirolimus (SRL) as major immunosuppressive therapy in lung transplant recipients.Method Retrospective analyses were conducted for the clinical data of all the patients undergoing lung transplantation in Wuxi People's Hospital between January 2011 and December 2014.Sixteen were given conversion treatment with Sirolimus in the postoperative irnmunosuppressive therapy.We analyzed the opportunity and reasons in the conversion treatment,and the safety,effectiveness and complications of the conversion treatment.Result The follow-up period was 8 to 25 months,and the median time of conversion was 6 months after operation (2-18 months).The indications of conversion concluded:malignant tumor (n =8),renal dysfunction (n =5),lymphangioleiomyomatosis (n =1) and intractable diarrhea caused by CNIs (n =2).Four cases suffered from interstitial pneumonitis associated with Sirolimus and one case suffered from spontaneous pneumothorax,and they all conversed back to CNIs.In those patients,cancer recurrence occurred in 4 cases (of them,there were 3 deaths),and 3 patients developed chronic rejection.Those recipients receiving the conversion treatment due to renal dysfunction showed recovery of renal function to some extent.Conclusion It's effective and safe to converse the immunosuppressive therapy based on Sirolimus.Sirolimus should be reduced or withdrawn when interstitial pneumonitis associated with Sirolimus occurred.

Objective To observe the protective effects of salidroside on glutamate-induced injury in cultured hippocampal neurons.Methods Primarily cultured hippocampal neurons from fetal Wistar rat were incubated with salidroside(10,20 and 40mg/L) for 24 hours,then glutamate(125?mol/L) was added for 15 minutes to induce injury.Cell viability was detected by MTT assay,the vigor of LDH was determined by biochemistry method,the apoptosis rates were anallyzed using Annexin V-FITC and PI labelling and Hoechst 33342 staining and flow cylometric assay.Fluorescent intensity of intracellular free calcium was observed with laser scanning confocal microscopy(LSCM).Results After the pretreatment with salidroside for 24 hours,the increases of LDH vigor and apoptosis rates and the decrease of cell viability caused by glutamate were resisted obviously.Salidroside inhibited the increase of Ca~2+ in cytoplasm significantly.Conclusion Salidroside can significantly resist the injury induced by glutamate.The neuroprotective activities of salidroside can be related to its ability to reduce Ca~2+ overload in cytoplasm.

OBJECTIVE:
The purpose of this study is to assess the effects of aging on air-conducted sound elicited cervical vestibular evoked myogenic potential (cVEMP) and ocular vestibular evoked myogenic potential(oVEMP) in normal people.
METHOD:
Sixty normal subjects were recruited for the vestibular evoked myogenic potential examination. Among them, 20-40 year-old group was setted as the first group, 41-60 year-old group was setted as the second group, > 60-year-old group was setted as the third group. Each group included 20 normal subjects. SPSS 16.0 software was used to analyze the data.
RESULT:
As the age growing, P1 latency prolonged, N1-P1 amplitude decreased, and amplitude asymmetric ratio increased in cVEMP; N1 latency prolonged, P1-N1 amplitude decreased, and amplitude asymmetric ratio increased in oVEMP.
CONCLUSION
With the age growing, the time of otolithic organ input pathways prolonged, the function of otolithic organ decreased and the decrease level may be asymeetrical on both sides.
