To investigate the effects of Tongxinluo capsule on sciatic nerve apoptosis in spontaneous type II diabetic KK/Upj-Ay mice, in order to explore its mechanism for improving diabetic peripheral neuropathy (DPN). KK/Upj-Ay mice were selected as the DPN animal model and randomly divided into the model, Tongxinluo low, middle and high group (1, 2, 4 g x kg(-1)). C57BL/6 mice were selected as the control group. Mice were given intragastrically for 12 weeks. Paw withdrawal latency, motor nerve conduction velocity (MNCV) and sensory nerve conduction velocity (SNCV) were detected. Apoptotic rate were detected by FCM. Bcl-2, Bax, Caspase-3 mRNA and protein expression in sciatic nerve were examined by Real-time PCR and Western blot. p38MAPK, p-p38MAPK expression were examined by Western blot. In this study,the authors found that Tongxinluo capsule could increase paw withdrawal latency, MNCV and SNCV. Apoptotic rate of sciatic, the expression of Bax and caspase-3 were lower, while Bcl-2 expression was higher in Tongxinluo group than those in model mice. The expression of p-p38MAPK significantly decreased in Tongxinluo group. The results showed that Tongxinluo capsule has protective effects on diabetic peripheral neuropathy of mice via inhibiting cell apoptosis and suppressing the expression of p-p38MAPK.

Objective To evaluate the application of intra-operative cholangiography in cholecystectomy. Methods A total of 442 patients with biliary calculi underwent cholecystotomy were reviewed. Results Of the 442 cases, 3 were false positive and 1 was false negative radiologically. The accuracy rate was 99.1%. Conclusion The results suggested that the application of intra-operative cholangiography could decrease the incidence of residual calculi and avoid unnessary exploration and trauma of the common bile duct.

Objective To develop a method for separation and determination of safrole and 6-methyl coumarin in cosmetics by GC-MS. Methods The cosmetics were extracted with methanol and then dehydrated,and filtrated through the membrane of 0.45 ?m. The filtration liquid was injected into GC and GC-MS for detection and quantitative analysis with external standard method. Results The recovery rates of safrole and 6-methyl coumarin were 101.3%-106.0% and relative standard deviations of safrole and 6-methyl coumarin were 0.9%-1.4% and 0.9%-2.1% respectively. The detection limits were 5 and 10 ?g/g. Conclusion This method is accurate and sensitive for detection of safrole and 6-methyl coumarin in cosmetic.

Objective To develop a high performance liquid chromatography method for the determination of methylisothiazolinones and chloro-methylisothiazolinoe in cosmetics. Methods The cosmetic samples were extracted with methanol. The analytes were separated with the mobile phase of V(Methanol)∶V(Water)= 25∶75 at the flow rate of 1.0 ml/min and detected at the wavelength of 276 nm. Results The linear range of the method was 0.05-100 mg/ml for methylisothiazolinone and 0.0125-25 mg/ml for chloro-methylisothiazolinoe. The limit of detection of methylisothiazolinone and chloro-methylisothiazolinoe were 0.08 and 0.2 ?g respectively. The recovery rates were 84.5%-93.9% with the RSD of 2.5%-9.4% (n=6) for methylisothiazolinone and 88.3%-92.9% with the RSD of 2.9%-5.8% (n=6) for chloro-methylisothiazolinoe. Conclusion The method is simple,rapid,accurate and is suitable for the determination of methylisothiazolinone and chloro-methylisothiazolinoe in cosmetics.

Chinese Pharmaceutical Journal 2018;53(13):1088-1092
OBJECTIVE: To prepare montelukast sodium orally disintegrating tablets and investigate the bioequivalence in Beagle dogs. METHODS: The orally disintegrating tablets were prepared by direct compression method,and the optimal formulation was screened by orthogonal test.HPLC-fluorescence method was developed for determination of montelukast sodium plasma concentration in Beagle dogs. RESULTS: The optimized formulation(1 000 tablets) was montelukast sodium 10.4 g, microcrystalline cellulose 60 g, cross linked povidone 30 g, mannitol 15 g, magnesium stearate 2 g, aerosil 1 g, aspartame 1 g, flavor 0.6 g.

Chinese Pharmaceutical Journal 2020;55(16):1354-1357
OBJECTIVE: To investigate the taste-masking effect of montelukast sodium orally disintegrating tablets using electronic tongue technology and human sensory evaluation and determine the optimum formulation. METHODS: Orally disintegrating tablets were prepared with five different concentrations of flavoring agents or without flavoring agent.The tastes of those tablets were determined by electronic tongue, and principal component analysis and linear discriminant analysis were used to evaluate differences of different formulations. The taste-masking effect of the tablets was investigated combined with electronic tongue analysis and sensory evaluation of subjects. RESULTS: The taste of orally disintegrating tablet was the best when the total amount of flavoring agent was 1.6 mg, and the ratio of sweetening agent to aromatic agent was 5∶3. CONCLUSION: The combination of electronic tongue and human sensory assess can evaluate the taste-masking effect of orally disintegrating tablets and provide the basis for determining the optimum formulation.
