The chemical ingredients of sediments from single Radix Aconiti Lateralis (Fuzi, in Chinese) decoction and Radix Aconiti Lateralis-Radix Glycyrrhizae (Gancao, in Chinese) decoction were evaluated separately by HPLC-MS for exploring their ingredients difference and discussing the mechanism of toxicity reduction of Fuzi-Gaocao herb-pair, even providing the experimental basis for extracting and purifying process of TCM preparations containing Fuzi-Gancao herb-pair. The sediments samples from single Fuzi decoction (FD) and Fuzi-Gaocao decoction (FGD) were prepared separately firstly. Then these samples were analyzed in the same chromatographic and mass spectrometry condition, estimating their HPLC-MS fingerprint and identifying their compounds by Q-TOFMS. As a result, 28 compounds in sediments samples from FD were obtained, among which 25 compounds and structures were confirmed. Besides, 36 compounds in sediments samples from FGD sample were obtained including 34 confirmed compounds and structures, among which there were 11 compounds from Gancao and 25 compounds from Fuzi. However, according to these confirmed compounds, alkaloids compounds in sediments samples from FGD were significantly different from that in sediments samples from FD. This result showed the fact that there would be some influences on alkaloid compounds in decoction after the combination of Gancao. In this study, the experiment basis of the mechanism of toxicity reduction of Fuzi-Gaocao herb-pair is provided. It also showed that much attention should be paid to the fact that there were great amount of alkaloid compounds, the effective compounds, in the sediments for which a comprehensive utilization in clinic and pharmaceutical process should be noted.

Objective To evaluate the effect of Diver CE aspiration thrombus catheter used in patients during the recovery of acute myocardial infarction (AMI) with percutaneous coronary intervention (PCI). Methods A total of 50 AMI patients were enrolled from January 2010 to December 2011. Twenty-ifve patients received PCI and used the Diver CE aspiration thrombus catheter (aspiration group);and the other 25 patients received routine PCI (routine PCI group). The basic characteristics, PCI characteristics, myocardial perfusion indexes and clinical data were compared and analyzed. Results There was no statistically difference between two groups in basic characteristics. Compared with the routine PCI group, higher rate of myocardial blush grade 3 but lower thrombus scores were found in the aspiration group. The incidence of no-lfow or slow-lfow were also lower in aspiration group (all P<0.05). The LVEF after 6 and 12 months were higher in the aspiration group (both P<0.05), no difference in MACE between the two groups. Conclusions Using the Diver CE thrombus aspiration in PCI is a simple and safe by method for treatment of acute myocardial infarction with high thrombosis burden. It can improve reperfusion decrease the rates of no-relfow on slow-relfow and can improve the long-term left ventricular function.

Objective:To observe the clinical efficacy of point application with Da Huang (Rhizoma Rhei Cruda) powder at Shenque (CV 8) plus moxa-salt hot compress on the umbilicus for preventing gastrointestinal adverse reactions after chemotherapy for non-Hodgkin lymphoma (NHL).Methods:A total of 60 cases with NHL under chemotherapy were divided into two groups by hospitalization order,with 30 cases in each group.The control group was treated with routine nursing and the observation group was additionally given point application with Da Huang (Rhizoma Rhei Cruda) powder plus moxa-salt hot compress on the umbilicus,to compare the effect in preventing gastrointestinal adverse reactions after chemotherapy between the two groups.Results:The occurrence rates of constipation,nausea,vomiting and poor appetite on the second day and fifth day after chemotherapy were obviously lower in the observation group than those in the control group,with statistically significant differences between the two groups (all P＜0.05).Conclusion:The point application with Da Huang (Rhizoma Rhei Cruda) powder at Shenque (CV 8) plus maxa-salt hot compress on the umbilicus can produce more significant efficacy in preventing the gastrointestinal adverse reactions after chemotherapy for NHL than routine nursing.Moreover,it is simple and easy to be used and popularized.

Objective To analyze the characteristics of tuberculosis (TB) in renal-transplant recipients from our hospital, and summarize the corresponding experiences in diagnosis and management.Methods A retrospective study was performed on 61 documented post-transplant TB cases out of the 2842 patients who received kidney transplantation in the First Affiliated Hospital of Sun Yat-sen University between Jan.1991 and Dec.2010.Results TB in the post-renal-transplant population in our hospital displayed the following characteristics:(1) High incidence (2.1％ ).54.1％ recipients were diagnosed within the first year post-transplant; (2) Lung was the most common site (77.0 ％).There was high prevalence (60.7 ％) of extra-pulmonary TB (lymphatic TB,23.0 ％; pleuritis,13.1 ％; graft,11.5％); (3) Fever (83.6 ％),cough (55.7 ％),sputum (41.0 ％) were the most common clinical manifestations.There were also emaciation (3.3 ％) and enlargement of lymph nodes (18.0 ％); (4) Chest X-ray and CT were of great value during TB diagnosis while purified protein derivative of tuberculin (PPD) skin test had little diagnostic value with a negative result in 56 cases (91.8 ％) ; (5) Liver function damage ( 16.4 ％),kidney function injury (39.3 ％) and peripheral nerve toxicity (3.3 ％) were the main adverse reactions of anti-tuberculosis chemotherapy,also the major cause of anti-TB failure; (6) Pre-transplant TB (17 cases) increased the probability of TB recurrence (4 cases,23.5 ％) post-transplantation; (7) The post-transplant TB patients were accompanied with cellular immune deficiency,resulting in overlapping infection of bacteria,viruses and fungi (19.7 ％); (8) 1- and 3-year patient/graft survival rate of patients with post-transplant TB was 85.2 ％/78.7 ％ and 85.2 ％/75.4 ％ respectively. The accumulative mortality rate reached to 14.8％,while overlapping infection was the major cause of death (66.7 ％).Conclusion Chinese renal transplant recipients still face a high risk of TB because of their immunecompromised state and epidemiological prevalence of the disease. For the high mortality rate and associated serious complications,rapid diagnosis and effective anti-TB chemotherapy are of great value for TB population.

Objective To discuss and analyze the diagnosis,management and surgical techniques for cranioplasty of skull vault defects and skull base reconstruction in order to raise the therapeutic effect. Methods The clinical data of 169 cases of skull vault and skull base defects treated with cranioplasty of skull vault defect and skull base reconstruction were retrospectively analyzed.Results Overlay tech- nique or inlay technique with imported titanium alloy mesh was used in 160 cases,and homologous bone was used in 9 cases.The surgical time ranged from 3 months to 8 years after injury.Eight cases presented with complications such as hematoma,subcutaneous effusion,infection and epilepsy postoperatively,but no operative death occurred.Conclusion For patients with skull vault defect with the diameter≥3 cm the best operative time is 3 months after injury,and for patients with intracranial and extracranial communica- ting tumors,skull base reconstruction can be performed when tumors are removed.Much attention should be paid to perioperative management and surgical skills.

OBJECTIVETo investigate the distribution of GAD67 and the co-localization with bNOS in the main olfactory bulb of GAD67-GFP knock-in mouse.

METHODSPolymerase chain reaction was applied to identify the genotype of GAD67-GFP knock-in mouse, the animals were sacrificed and frozen sections of olfactory bulb were prepared. The Nissl-staining was performed to show an framework of the neuron in the olfactory bulb. The distribution of GAD67 and co-localization with bNOS were detected by immunofluorescence technique.

RESULTSThe proportion of GAD67-positive cells among DAPI-positive cells were (42.98 ± 0.92)% in glomerular layer, (23.64 ± 0.84)% in mitral cell layer and (77.75 ± 0.84)% in granule cell layer; the bNOS-positive cells mainly existed in glomerular layer and mitral cell layer, very few in granule cell layer. No co-localization of GAD67 and bNOS in granule cell layer and mitral cell layer was found, but there was dispersed distribution in glomerular layer.

CONCLUSIONGAD67-positive neurons mainly appear in glomerular layer and granule cell layer, and the bNOS is mostly expressed in glomerular layer and mitral cell layer; while the co-localization of GAD67 and bNOS only occurs in glomerular layer of olfactory bulb.

Objective To analyze the clinical and epidemiological characteristics of human avian influenza A (H7N9 ) epidemic in Jiaxing City,and to provide scientific basis for the control and prevention of the disease.Methods The epidemiological and clinical information of 15 cases of human infection with avian influenza A (H7N9)reported from April, 2013 to May,2015 were collected.Sample of patients and external environmental samples of suspected exposure were collected and detected by real-time PCR.The epidemic distribution and clinical characteristics were analyzed.Results Fifteen cases of human infection with H7N9 were confirmed from April,2013 to May,2015,including 11 cases of death (77.33%).The confirmed cases mostly reported in winter and spring,and 9 confirmed cases were over 60 years,and male case proportion was higher than women (1.5∶1 ).Most of cases (66.67%)were sporadic and occurred in rural areas,but no epidemiological association was observed among the cases.Fever (100%),cough (66.67%),and wheezing and tightness in chest (33.33%)were common initial symptoms.The chest imaging examination of patients showed ground glass opacity and patchy consolidation,and 7 cases had simple pleural effusion.Twelve of confirmed cases had other chronic diseases.Eleven cases of death had appeared multiple medical comorbidities,such as respiratory failure (6/1 1 ),pulmonary embolism (4/1 1 ),multiple systemic organ failure (3/1 1 ),and heart cerebrovascular embolization (2/11).Twelve cases had been exposed to the live poultry markets where the positive rate of novel influenza A (H7N9) virus in environmental specimens was 7.69%(25/325).One of the 252 close contacts to confirmed cases appeared mild flu-like symptoms.No positive result related to novel influenza A (H7N9)virus nucleic acid was detected from each close contact's throat swabs.Conclusion Human infections with avian influenza A (H7N9)virus showed obvious seasonal distribution in Jiaxing.Elderly men,especially those with chronic diseases were the high risk people of human infection with H7N9 avian influenza.The infection might be associated with the exposure to live birds.Standard management of live poultry markets is the key measure in preventing and controlling H7N9 virus infection among population.

Objective: To explore whether acupuncture can improve sleep disturbance, cognitive impairment and emotional disorders caused by sleep deprivation, and its association with the attenuation of oxidative stress injury in prefrontal cortex. Methods: Fifty-two male Sprague-Dawley rats were randomly divided into a control group (n=10), a model group (n=14), a manual acupuncture (MA) group (n=14), and a sham-MA group (n=14). All the groups were established as sleep deprivation models via the modified multiple platform method, except for the control group. Rats in both the MA group and the sham-MA group received corresponding intervention, respectively. After modeling and intervention, the four groups received three behavioral tests, namely sleep monitoring, by comprehensive lab animal monitoring system (CLAMS), Morris water maze (MWM) test and open-field test (OFT), followed by oxygen free radical level test and Western blot (WB) detection for the expression levels of Bax and Bcl-2. Results: The MA group derived more sleep time within 24 h than either the model group or the sham-MA group (both P<0.05). On MWM orientation navigation test day 1, there were no significant differences in escape latency among the control, MA and sham-MA groups (P>0.05), and the escape latency was significantly shorter in these three groups than that in the model group (all P<0.05). On test day 4, the escape latency was markedly shorter in the MA group than that in either the model group or the sham-MA group (both P<0.05); meanwhile, the MA group showed significantly better performance compared with these two groups in space probe test (both P<0.05). In OFT, compared with the control group, there was a significant decline in the horizontal movement score in the other three groups (all P<0.05), and the decrease was more significant in the model group and the sham-MA group than that in the MA group (both P<0.05). The superoxide dismutase (SOD) content was markedly higher and the malondialdehyde (MDA) content was markedly lower in the MA group than those in the model group and the sham-MA group (all P<0.05). Compared with the model group and the sham-MA group, the expression of Bax was significantly lower and the expression of Bcl-2 was significantly higher in the MA group (all P<0.05). Conclusion: MA therapy can lengthen the sleep time in sleep-deprived rats and improve learning and memory impairments induced by sleep deprivation, and the underlying mechanism may be associated with the enhancement of antioxidant capacity in the prefrontal cortex and the inhibition of hippocampal neuronal apoptosis.
