Objective To explore the cognitive function of the theory of mind(TOM) in early-onset schizophrenia from faux pas recognition and belief understanding dimensions.Methods 41 early-onset schizophrenias (EOS) and 40 normal adolescents were interviewed by the Chinese version of faux pas recognition task and theory of mind picture-sequencing task(ToM-PST),then early-onset schizophrenias cognitive features were analyzed.Results ①In faux pas recognition task,compared with healthy subjects,EOS showed significantly less total scores (16.11±6.34 vs 20.86±7.79,P＜0.05)and subscores of understanding faux pas questions (9.88±4.11 vs 13.27± 6.07,P＜0.05).In faux pas recognition scores(6.72±2.60vs 7.58±2.20) and control questions(9.83±0.44vs 9.97± 0.16) had no statistically significant difference (P＞0.05).②In ToM-PST task,early-onset schizophrenic patients also had significantly less total score(17.29±3.38 vs 21.48± 1.73,P＜0.01),subscores of understanding first order belief,first order error belief,second order belief,second order error belief,third order error belief,sense of reality,reciprocity,fraud,detecting fraud compared to normal controls had significant difference (all P＜ 0.05 or 0.01).③ The correlation between clinical course time and PANSS score and its subscores of the theory of mind picture-sequencing and faux pas task was non-significant(P＞0.05)except the subscores of understanding the first order belief (P＜0.01).Conclusion The theory of mind is apparent damage in early onset schizophrenia and non-significant correlation is found with psychiatric symptoms.

With the development of natural products, the research activities on the solubilization methods of water-insoluble natural products have been carried out worldwide. Big molecular weight and poor solubility of most natural active ingredients lead to a very poor oral absorption and low bioavailability, which has extremely limited their development in pharmaceutical fields and clinical application. As a result, it is necessary to find out a suitable technique to improve the solubility and enhance the oral bioavailability of insoluble natural drugs. Based on the related references published in these years, this review introduced some new techniques to improve the solubility and bioavailability of natural drugs, including prodrugs, inclusion complex, solid dispersion, cocrystals, osmotic pump, liquisolid compacts, micronization, self-microemulsifying, nanosuspensions, lipsomes, polymeric micelles and so on, and summarized the theory, characteristics, application range, application examples, problems and development direction of each technique.

Objective To evaluate the efficacy of DSA-guided percutaneous transhepatic gallbladder catheter drainage (PTGCD) in treating aged patients with acute cholecystitis complicated by severe diseases. Methods The clinical data of 15 aged patients with acute cholecystitis or complicated by severe diseases, who were encountered at authors’ hospital in the past three years and were treated with PTGCD, were retrospectively analyzed. The clinical results were discussed. Results PTGCD was successfully accomplished with single procedure in all 15 patients. Abdominal pain was relieved within one to three days, and the abdominal symptoms and signs subsided or disappeared. Reexamination of routine blood test showed that the white blood cell count decreased to normal range in 1 - 2 weeks, and complete cure was achieved in some patients. Secondary surgery was carried out in some patients after the clinical condition was improved. During the follow-up period no complications occurred in all patients except one who developed biliary leakage after the catheter was retrieved two weeks after the treatment. Conclusion For the treatment of complicated acute cholecystitis in aged patients who are not suitable to receive surgery, DSA-guided percutaneous transhepatic gallbladder catheter drainage is an ideal therapeutic means as it can significantly relieve clinical symptoms.

Objective To observe the radiosensitization effect of Aidi injection on human lung adenocarcinoma A549 cells, and to analyze its possible mechanism.Methods ① A549 cells were treated with different concentrations of Aidi injection (1.875, 3.75, 7.5, 15, 30, 60 mg/mL) for 24 hours, and in the mean time, a blank control group was set up; the effect of Aidi injection on lung adenocarcinoma A549 cells proliferation was detected by methyl thiazolyl tetrazolium (MTT) assay, and the 10% cell growth inhibitor concentration (IC10) was calculated. ② The experiments were divided into blank control, Aidi control, radiation and Aidi pretreatment groups. The Aidi control group was incubated for 24 hours by Aidi injection IC10; the radiotherapy group was given X-ray irradiation of 4 Gy followed by incubation for 24 hours; the Aidi pretreatment group was incubated for 24 hours by Aidi injection IC10 and then given X-ray irradiation of 4 Gy; the blank control group received equal volume of normal saline and was incubated for 24 hours. The survival fraction (SF) value was detected by cell colony formation assay; the protein levels of the serine phosphorylation at 139 locus of histone (γ-H2AX protein), the key protein in homologous recombination repair pathway (Rad51 protein) and the cell autophage characteristic protein (LC3 protein) were detected by Western Blot; the formation of autophagosome was observed by transmission electron microscope.Results Aidi injection possessed the suppression of the growth of human lung adenocarcinoma A549 cells, the proliferation of the cells in various Aidi groups was lower than that in the blank control group, with the increase in drug concentration, the A549 cell growth inhibition ratio (IR) was gradually increased, representing a dose dependent manner, and the IC10 was 3.09 mg/mL. Compared with the blank control group, the SF value in Aidi control group was not significantly different [(94.7±3.85)% vs. (100.0±0.00)%,P > 0.05], the SF value in radiation group was decreased [(71.8±5.9)% vs. (100.0±0.0)%,P < 0.05], and in Aidi pretreatment group, the value was further decreased compared with that in radiation group [(51.9±4.7)% vs. (71.8±5.9)%,P < 0.05]. Compared with the blank control group, the expression of γ-H2AX protein in the three treatment groups was significantly increased, the degree of increase in Aidi pretreatment group was the most obvious, and it was significantly higher than that in radiation group (gray value: 1.44±0.11 vs. 0.93±0.09,P < 0.05). But the expression of Rad51 protein was the highest in radiation group, and it was higher than that in Aidi pretreatment group (gray value: 1.37±0.07 vs. 0.78±0.04, P < 0.05). Compared with the blank control group, the LC3Ⅱ/LC3Ⅰ value in Aidi control group, radiation group and Aidi pretreatment group were increased, and the degree of increase in Aidi pretreatment group was the most significant (0.35±0.06, 0.37±0.07, 0.49±0.06 vs. 0.05±0.04, allP < 0.05). Under transmission electron microscope, compared with the blank control group, the autophagosome in all treatment groups was increased to some extent, and the degree of increase in Aidi pretreatment group was the most remarkable.Conclusion Aidi injection has the enhancing effect of radiosensitization on human lung adenocarcinoma A549 cells, and its mechanism is possibly related to the up-regulation of A549 cell autophagy level.

A set of central composite design experiments were designed by using four factors which were ethanol amount, ethanol concentration, refrigeration temperature and refrigeration time. The relation between these factors with the target variables of the retention rate of schizandrol A, the soluble solids content, the removal rate of fructose and the removal rate of glucose were analyzed with Bayesian networks, and ethanol amount and ethanol concentration were found as the critical process parameters. Then a network model was built with 2 inputs and 4 outputs using back propagation artificial neural networks which was optimized by genetic algorithms. The R2 and MSE from the training set were 0.983 8 and 0.001 1. The R2 and MSE from the test set were 0.975 9 and 0.001 8. The results showed that network analysis method could be used for modeling of Schisandrae Chinensis Fructus ethanol precipitation process and identify critical operating parameters.
