Objective:To investigate the characteristics of implicit memory and its related factors in schizophrenic patients with negative and positive symptoms.Methods:Ninety-three schizophrenic patients (including 52 cases of negative symptoms group and 41 cases of positive symptoms group) and 30 normal controls (normal group) were tested with the method of Chinese character word completion method. The reaction time and correct rate were recorded and compared with analysis of variance and t-test, and the correlation with demographic factors was analyzed with Pearson correlation analysis. Results:Accuracy of implicit memory test in schizophrenia group: there were statistically significant differences in the accuracy of patients with different course of disease (≤5 years: (38±5)%, 5-15 years: (34±8)%, ≥15 years: (34±7)%, P<0.05).The differences were statistically significant in the accuracy of patients with different education levels(primary school: (35±6)%, junior and senior high school: (34±7)%, secondary college education and above: (39±5)%, P<0.05).The accuracy of patients with education years < 10 years ((34±7)%) was significantly lower than those with education years ≥10 years ((37±6)%, P<0.05).Reaction time results of implicit memory test in schizophrenia group : there were significant differences in reaction time of patients with different disease course(≤5 years: (3 248±971)ms, 5-15 years: (3 515±672)ms, ≥15 years: (3 925±842)ms, P<0.05).The differences were statistically significant in the reaction time of workers ((3 495±712)ms), farmers ((3 870±878)ms) and soldiers ((3 024±924)ms, P<0.05).The reaction time of patients with clozapine ((3 869±871)ms) was significantly higher than that of patients with olanzapine ((3 393±626)ms, P<0.05).Intergroup results of accuracy: the accuracy of normal control group ((40±5)%) was significantly higher than that of negative symptom group ((33±7)%, P<0.01).The accuracy of negative symptom group was significantly lower than that of positive symptom group ((37±6)%, P<0.01).Intergroup reaction time results: the reaction time of normal control group ((2 660±667)ms) was significantly lower than that of negative symptom group ((3 678±951)ms, P<0.01) and positive symptom group ((3 072±865)ms, P<0.05).The reaction time of negative symptom group ((3 678±951)ms)was significantly higher than that of positive symptom group( P<0.01).There was significant negative correlation between the accuracy of implicit memory and the course of disease in schizophrenia ( r=-0.22, P<0.05). Conclusion:The implicit memory of schizophrenic patients is related to the course of disease, taking drugs, and occupation.There may have differences in implicit memory between patients with negative and positive symptoms of schizophrenia.
RESUMO
BACKGROUND@#Microvascular complications in type 2 diabetes (T2DM), including diabatic retinopathy (DR), diabetic kidney disease (DKD), diabetic peripheral neuropathy (DPN) are the leading causes of visual loss, end-stage renal disease or amputation, while the current therapies are still unsatisfactory. Chinese medicine (CM) has been widely used for treating diabetic mellitus. However, most of the previous studies focused on the single complication. The role of CM treatment in T2DM patients with 2 or multiple microvascular complications is not clear.@*OBJECTIVE@#To appraise the curative effect of CM in T2DM patients with 2 or multiple microvascular complications, and to compare the effects of stationary treatment and individualized treatment in T2DM patients with microvascular complications.@*METHODS@#This trial will be an 8-center, randomized, controlled study with 8 parallel groups. A total of 432 patients will be randomized to 8 groups: DR study group (32 cases) and a corresponding control group (32 cases), DR+DKD study group (64 cases) and a corresponding control group (64 cases), DR+DPN study group (64 cases) and a corresponding control group (64 cases), DR+DKD+DPN study group (56 cases) and a corresponding control group (56 cases). The control group will receive stationary treatment, and the study group will receive individualized treatment based on CM syndrome differentiation in addition to stationary treatment. The study duration will be 50 weeks, comprising a 2-week run-in period, 24 weeks of intervention, and 24 weeks of follow-up. The outcomes will assess efficacy of treatment, improvement in CM symptoms, safety assessments, adherence to the treatment, and adverse events.@*CONCLUSION@#This study will provide evidence of evidence-based medicine for CM treatment in two or multiple microvascular complications caused by T2DM.

RESUMO
Ketogulonicigenium vulgare has been widely used in vitamin C two steps fermentation and requires companion strain for optimal growth. However, the understanding of K. vulgare as well as its companion strain is still preliminary. Here, the complete genome of K. vulgare Hbe602 was deciphered to provide insight into the symbiosis mechanism and the versatile metabolism. K. vulgare contains the LuxR family proteins, chemokine proteins, flagellar structure proteins, peptides and transporters for symbiosis consortium. Besides, the growth state and metabolite variation of K. vulgare were observed when five carbohydrates (D-sorbitol, L-sorbose, D-glucose, D-fructose and D-mannitol) were used as carbon source. The growth increased by 40.72% and 62.97% respectively when K. vulgare was cultured on D-mannitol/D-sorbitol than on L-sorbose. The insufficient metabolism of carbohydrates, amino acids and vitamins is the main reason for the slow growth of K. vulgare. The combined analysis of genomics and metabolomics indicated that TCA cycle, amino acid and nucleotide metabolism were significantly up-regulated when K. vulgare was cultured on the D-mannitol/D-sorbitol, which facilitated the better growth. The present study would be helpful to further understand its metabolic structure and guide the engineering transformation.

During 8th-14th Jan., 2013, severe particulate matter (PM) pollution episodes happened in Beijing. These air pollution events lead to high risks for public health. In addition to various PM chemical compositions, biological components in the air may also impose threaten. Little is known about airborne microbial community in such severe air pollution conditions. PM2.5 and PM10 samples were collected during that 7-day pollution period. The 16S rRNA gene V3 amplification and the MiSeq sequencing were performed for analyzing these samples. It is found that there is no significant difference at phylum level for PM2.5 bacterial communities during that 7-day pollution period both at phylum and at genus level. At genus level, Arthrobacter and Frankia are the major airborne microbes presented in Beijing winter.samples. At genus level, there are 39 common genera (combined by first 50 genera bacterial of the two analysis) between the 16S rRNA gene analysis and those are found by Metagenomic analysis on the same PM samples. Frankia and Paracoccus are relatively more abundant in 16S rRNA gene data, while Kocuria and Geodermatophilus are relatively more abundant in Meta-data. PM10 bacterial communities are similar to those of PM2.5 with some noticeable differences, i.e., at phylum level, more Firmicutes and less Actinobacteria present in PM10 samples than in PM2.5 samples, while at genus level, more Clostridium presents in PM10 samples. The findings in Beijing were compared with three 16S rRNA gene studies in other countries. Although the sampling locations and times are different from each other, compositions of bacterial community are similar for those sampled at the ground atmosphere. Airborne microbial communities near the ground surface are different from those sampled in the upper troposphere.

To analyze the regularity in combined medication with Xiyanping injection (Xiyanping for short) in the real world by as- sociation rules. Totally 5 822 patients using Xiyanping injection was collected from the 18 Class III Grade I hospitals nationwide to study the combined medication information of the patient with lung infection and make the analysis by using association rules and Apriori. According to the results, major drugs combined with Xiyanping in treatment of lung infection included compound amino acid, inosine, coenzyme A, cytidine triphosphate, vitamin C. Common drugs combined with Xiyanping can be divided into 5 categories: nutrition support therapy (vitamin C, compound amino acid) , coenzymes (coenzyme A, cytidine triphosphate, inosine), expectorants and antiasthmatics (ambroxol, salbutamol, doxofylline), hormones (dexamethasone, budesonide), antibiotics (mainly cefminox). The main combined medicines mostly conformed to the regularity for drugs treating lung infection. In addition, there were two most common medical combination models: the model for Xiyanping combined a single medicine is Xiyanping + nutrition support therapy, while the model for Xiyanping combined two or more than two medicines is Xiyanping + nutrition support therapy + coenzyme. Pharmacologically, Xiyanping is mostly combined with western medicines with similar pharmacological effects to substitute or supplement the antibiotic effect in treating lung infection. However, further studies shall be conducted for the safety and rationality of the combined medication based on clinical practices, in order to provide reference for clinical medication.

This study aims to assess if adverse drug reactions (ADRs) to parenterally administered salvianolate are allergic in origin. Hospital information system (HIS) data from 20 hospitals in China were used to carry out a retrospective nested case control design study. Included were patients who received dexamethasone for suspected allergic reactions after receiving parenterally administered salvianolate. These were compared with non-allergic reaction people. Single factor logistic regression and multiple factor logistic regression were used to analyze data. Condition on admission, allergic history, dosage, disease status and drug combinations were taken into account in cases of suspected allergic reactions. After analysis in two subgroups we found that the condition on admission had a significant effect, P values was < 0.000 1 on suspected cases of allergic reactions in the first subgroup analysis. For the second subgroup analysis, we found condition on solvents had a significant effects, P values was 0.005 1 on suspected cases of allergic reactions. We also found that using other four injections at the same time as parenterally administered salvianolate could be risky factors in suspected cases of allergic reactions. For the second subgroup analysis combining using three injections could increase risks. However, further research for verification is required. This study can provide guidance for safe clinical practice in using parenterally administered salvianolate.

Objective To investigate the biological safety of silicon membrane embedded permanent magnets implanted into canine, so as to evaluate the safety of a micturition alert device designed on the principle of compass. Methods Twelve adult male dogs (weighing 11-12 kg) were divided into experimental group (8 dogs) and control group (4 dogs ). The experimental group was implanted with a silicon membrane embedded NdFeB magnet, which was 10 mm in diameter and 3 mm in thickness and with a magnetic induction intensity of 0. 3 Tesla at the center of the pole face surface. The control group was implanted with a silicon membrane embedded NdFeB alloy with the same dimensions. The grafts were sutured onto the anterior surface of the bladder wall. The dogs were then allowed to live for one year. Both the survival and local pathology around the grafts were observed after implantation. And the pre-operation urine and post-operation urine were compared between the two groups. Results One dog in the experimental group died from operation complications 10 hours after operation, another dog had intestinal obstruction 3 weeks after operation because iron wires in the intestinal tract was caught up by the permanent magnet. The rest 6 dogs in the experimental group and 4 dogs in the control group had no abnormalities in spirit, appetite, urine or stool, and there were no infections. The animals were sacrificed one year after operation. Adhension was found between the epiploon and the bladder wall around permanent magnets in these 10 dogs; the fibrous capsule around the permanent magnets was thin, and the local bladder wall below permanent magnets was thickened, with normal bladder mucosa. Grade 2 inflammatory reaction and fibrous capsule of the local tissue were noted around the grafts. The findings of urine routine were normal before and after operation. Conclusion NdFeB permanent magnets embedded with silicon membrane are biologically safe for clinical application, which warrante further investigations.
RESUMO
BACKGROUND/OBJECTIVE: To study the effectiveness of knee-tendon to bladder artificial reflex arc in dogs. METHODS: In 6 beagles, the proximal end of the right L5 anterior motor root and the distal end of the right S2 anterior root were anastomosed to build a knee-tendon to bladder reflex, whereas the right L5 posterior sensory root was kept intact. Action potential (AP) curves and electromyograms (EMGs) of the detrusor muscle, the intravesical pressure, horseradish peroxidase (HRP)-labeled neurons, and the passing rates of myelinic nerve fibers were calculated to evaluate its feasibility. RESULTS: AP curves and EMG detected in all 6 dogs were similar to those of the control. Six and 18 months after surgery, the means for bladder contraction induced by percussion of the right knee-tendon were 38 +/- 27% and 62 +/- 5% that of the normal control, respectively. The mean duration times induced by percussion of the right knee-tendon at 6 and 18 months after surgery were 51 +/- 37% and 84 +/- 12% that of the normal control, respectively. HRP retrograde tracing and neurohistologic observation indicated the feasibility of the artificial reflex arc. CONCLUSIONS: Our data showed the effectiveness of bladder innervation below the level of spinal cord injury producing urination by knee-tendon to bladder reflex contractions, and therefore, might provide a new clinical approach for restoring bladder function in individuals with paraplegia.
