Objective:To evaluate the clinical efficacy of acupuncture plus tuina in treating cervical vertigo (CV).Methods:One hundred CV patients were randomized into an observation group and an acupuncture group by the random number table,with 50 cases in each group.The acupuncture group received acupuncture at Xiang Ba Zhen (eight acupoints on the nape);the observation group received tuina treatment in addition to the Xiang Ba Zhen acupuncture.The two groups were both treated once every other day for 10 sessions in total.The two groups were examined by transcranial cerebral Doppler (TCD) before and after the treatment,and their therapeutic efficacies were evaluated.Results:After the treatment,the mean velocity (Vm) of vertebral artery (VA) and basilar artery (BA) showed significant improvement in both groups (all P＜0.001);there were significant differences in the Vm of VA and BA between the two groups (both P＜0.05).The total effective rate was 100.0％ in the observation group versus 82.0％ in the acupuncture group,and the difference was statistically significant (P＜0.01).Conclusion:Xiang Ba Zhen acupuncture as a monotherapy or used together with tuina can improve CV,but Xiang Ba Zhen plus tuina can produce a more significant efficacy.

The study aims to develop a rapid, sensitive and specified method of liquid chromatography with heated electrospray ionization tandem mass spectrometry (LC-HESI/MS/MS) for simultaneous determination of amlodipine, benazepril and benazeprilat in human plasma using amlodipine-d4 and ubenimex as internal standards (ISs). Selected reaction monitoring (SRM) with heated electrospray ionization (HESI) was used in the positive mode for mass spectrometric detection. Analytes and ISs were extracted from plasma by simple protein precipitation. The reconstituted samples were chromatographed on a C18 (100 mm x 4.6 mm, 5 microm) column with mixture of methanol-acetonitrile-5 mmol.L- ammonium acetate-formic acid (30 : 30 : 40 : 0.1) as mobile phase at a flow rate of 0.6 mL.min-1. The standard curves were demonstrated to be linear in the range of 0.02 to 6.00 ng.mL-1 for amlodipine, 0.2 to 1,500 ng.mL-1 for benazepril and benazeprilat with r2>0.99 for each analyte. The lower limit of quantitation was identifiable and reproducible at 0.02, 0.2 and 0.2 ng mL-1 for amlodipine, benazepril and benazeprilat, respectively. The intra-day and inter-day precision and accuracy results were within the acceptable limit across all concentrations. The plasma samples were stable after four freeze-thaw cycles and being stored for 93 days at -20 degrees C. The method was applied to a pharmacokinetic study of a fixed-dose combination of amlodipine and benazepril on Chinese healthy volunteers.

AIM: To investigate the autophagy of breast cancer cells induced by baicalein and to explore its mechanism.METHODS: The effects of baicalein on the viability of MCF-7 cells and 4T1 cells were investigated by MTT assay, and the dosage of the drug was determined.The expression levels of microtubule-associated protein 1 light chain 3-II (LC3-II) and LC3-I in the MCF-7 cells and 4T1 cells treated with baicalein at doses of 25, 50 and 100 μmol/L, or combined with autophagy inhibitor 3-methyladenine (3-MA) were determined by Western blot.In order to confirm the role of baicalein in autophagy, the effect of 3-MA on the apoptosis of both MCF-7 cells and 4T1 cells induced by baicalein was analyzed by flow cytometry.The protein levels of p-mTOR, mTOR, p-AKT and AKT were examined by Western blot and the role of AKT-mTOR pathway in the induction of autophagy in breast cancer induced by baicalein was determined by the combination of activators.RESULTS: Baicalein at 50 μmol/L and above doses significantly inhibited the viability of breast cancer cells in a dose-and time-dependent manner.The expression of LC3-II/LC3-I in both MCF-7 cells and 4T1 cells was significantly enhanced after the action of baicalein, and the ratio of LC3-II/LC3-I was significantly decreased after 3-MA addition.The results of flow cytometry showed that, compared with baicalein group, the combination of baicalein and 3-MA promoted the levels of necrosis and apoptosis.Moreover, the protein levels of p-mTOR and p-AKT were significantly decreased and were rescued by EGF, while their total protein levels were not changed.CONCLUSION: Baicalein induces autophagy through AKT-mTOR pathway both in MCF-7 cells and 4T1 cells.

Objective To investigate the pathogen distribution and susceptibility profile of fungal isolates from bloodstream infections,and valuate the clinical utility of G test in diagnosis of fungal infections for the purpose to improve antifungal therapy.Methods A retrospective analysis was carried out to analyze the fungal pathogens isolated from bloodstream infections in the First Affiliated Hospital of Nanjing Medical University during the period from January 2013 through December 2015 and their antimicrobial susceptibility.Results A total of 114 fungal strains were isolated from bloodstream infections during the 3-year period,most of which were Candida (99/114,86.8％),especially Candida albicans (30.7％).About 41.2％ (47/114) of the fungal strains were isolated from Department of Thoracic Surgery (10,5 and 4 strains in 2013,2014 and 2015),Hematology (11 strains in 2014),and ICU (7 strains in 2014).Antimicrobial susceptibility testing showed that all the fungal strains (100％) were susceptible to amphotericin B,but 83.5％ susceptible to itraconazole (the lowest).G test was positive before the result of blood culture in 13 of the 54 patients who received G test.Conclusions Candida was the most common fungus in fungal bloodstream infection.Amphotericin B is the most active antifungal agent in vitro.Blood culture combined with serological test can provide clinicians an earlier and reliable diagnosis.

Objective: To observe the effects of acupoint thread-embedding therapy and low-carbohydrate diet therapy on obese patients with food addiction. Methods: Sixty-five eligible patients were randomized into a thread-embedding group of 33 cases and a diet group of 32 cases to respectively receive 12-week treatment. Before treatment, after treatment and at 6-month follow-up, the two groups were observed and compared in terms of body mass (BM), waist circumference (WC), hip circumference (HC), waist-to-hip ratio (WHR), body mass index (BMI), body fat rate (BFR), basal metabolic rate (BMR) and Yale food addiction scale version 2.0 (YFAS 2.0). Results: At the end of treatment, there were no significant differences in the general efficacy, and the improvements in BM, BMI, WC, HC, WHR and BFR between the thread-embedding group and diet group (all P>0.05). At follow-up, the thread-embedding group showed more significant improvements in all the aforementioned indicators compared with the diet group except HC (all P<0.05). At the end of treatment and follow-up, BMR and YFSA 2.0 had more significant improvements in the thread-embedding group than in the diet group (all P<0.05). Conclusion: Acupoint thread-embedding therapy can produce significant efficacy in treating obese patients with food addiction; it can improve the food addiction state and work better in maintaining the efficacy compared with low-carbohydrate diet therapy.

Ectopic spontaneous activity originated from the injured dorsal root ganglion (DRG) neurons in rats was recorded through single dorsal root fiber. The firing patterns induced by veratridine and aconitine, inhibitors of inactivation gate of sodium channel operating on different binding sites, were compared. In the same neuron, veratridine (1.5 approximately 5.0 micromol/L) caused slow wave oscillations of interspike intervals (ISIs), while aconitine (10 approximately 200 micromol/L) caused tonic firing. Moreover, even if the background firing patterns were various and the reagent concentrations used were different, veratridine and aconitine still induced slow wave oscillations and tonic firing patterns, respectively. The results suggest that veratridine and aconitine induce different firing patterns in injured DRG neurons, which may relate to their inhibitory effects on different binding sites of the sodium channel.

This paper is a follow-up study of 329 children in factory-run nurseries in urban Shanghai. The investigation lasted for a period of one year for each index-child, focusing on the conditions of nutrition, development and diseases of the children of various ages.Comparison between nutritionl findings and RDA of China disclosed that calorie intake of most of the index-child groups were 80-85% of RDA, the only exception being the 6-12 months group where the average calorie intake showed 90%. Protein intake of all groups was over 80% of RDA. Fe intake was lower than RDA, except for 18-month-old and over.Weight and height of the children were compared with the anthropo-metric data established in 1985 (1985 data) for Shanghai children under six years of age. It was found that the average weight and height appeared differently according to their age. Average weight of children under one year old was slightly higher than 1985 data, while average height was lower than 1985 data once the children reached 10 months old. Average weight, however, became lower than the 1985 data after the children were two years old. Over 60% of the index between 6-18 months old suffered from anemia (IDA).Accordingly, it is requested that calorie and iron intake should be supplemented.
