The apprentice system is the principal succession method of ancient Chinese medicine. Masters pass down knowledge via verbal instructions as well as personal deeds, and apprentices are unconsciously influenced deeply within by what they see and hear from masters. That is where the strong point of the system. However, at the same time, apprentices are confined by their master’s instructions and learn only a part of the knowledge. It is the profound meaning rather than the form, that truly represents the modern value of the system. Traditional Chinese medicine stresses the cultivation of medical ethics, purification of learning motivation, study of classic works, solid foundation of basic skills and clinical practice. It also advocates that apprentices should be led and taught in accordance to his aptitude.

Great achievements have been made on researches about Chinese Medicine education in modern Jiangsu Provice, which includes Shanghai and Nanjing before the year 1927. Through the researches, not only have volumes of valuable historical materials been saved and reorganized, but also plentiful academic achievements of high levels have been gained. However, generally speaking, the research work is not perfect enough. Much more progress can be made by further mining the historical materials, applying researh methods, developing different perspectives and so on.

Objective To assess the anticonvulsant effect of midazolam, thiopental and propofol on the convulsion induced by ropivacaine in rats and the underlying mechanism.Methods Fifty male SD rats, 4-6 months of age, weighing 250-300 g were randomly divided into five groups of 10 animals each : (1) control group (C); (2) ropivacaine group; (R) (3) midazolam-ropivacaine group (MR); (4) thiopental-ropivacaine group (SR) and (5) propofol-ropivacaine group (PR) . In control group normal saline 2 ml was infused i.v. . In ropivacaine group (R) 0.75% ropivacaine was infused i.v. at 0.5 ml?min-1 until convulsion occurred. In midazolam - ropivacaine group (MR) midazolam 0.23 mg?kg-1 was injected i.v. 3 min before 0.75% ropivacaine infusion. In SR and PR groups thiopental 2 mg?kg-1 or propofol 1 mg?kg-1 was injected i.v. 1 min before 0.75% ropivacaine infusion. As soon as convulsion occurred ropivacaine infusion was stopped. The animals were decapitated and their brains were removed and kept in liquid nitrogen for determination of the contents of excitatory ammo-acids (aspartic acid and glutamic acid) and the inhibitory amino-acids [glycine and ?-amino butyric acid (GABA)] by high-performance liquid chromatography . The amount of ropivacaine infused in each group was recorded and calculated.Results The dose of ropivacaine needed to produce convulsion was 4.6?0.5 mg?kg-1 in group R and was significantly increased in the 3 groups pretreated with general anesthetics and was 2.96 times the dose in group R in MR group, 2.84 times in SR group and 1.54 times in PR group. The 4 amino-acid concentrations in the brain were significantly higher in group R than in control group. Compared to group R the Asp, Gly and GABA concentrations were significantly lower in group MR and PR but in group SR only Asp concentration was significantly lower. There was no significant difference in glutamic acid concentration among the4 roopivacaine groups (group 2-5).Conclusion Midazolam, thiopental and propofol can all increase the dose of ropivacaine needed to induce convulsion and midazolam and thiopental are more effective than propofol.

OBJECTIVE: To observe the mouse nerve growth factor on early intervention in rats with acute carbon monoxide intoxication delayed encephalopathy control effects, and preliminarily discuss the pathogenesis of delayed encephalopathy. METHODS: Ninety-two weight only 180-230 g, male Wistar rats were randomly divided into two experimental groups (n=40), and a healthy control group (n=12), namely the CO poisoning group (COP) of the group; mouse nerve growth factor (NGF plays group); healthy controls (NC group). Experimental group was according to 150 mL·kg-1 intraperitoneal injections of CO in the preparation of animal model of acute carbon monoxide poisoning, in the control group rats were injected with equal volume of air. NGF group rats were injected within 30 min after poisoning muscle injection of mouse nerve growth factor, once a day, every time 18 μg·kg-1, total 7 days; Control group and the COP were given intramuscular isodose physiological saline. NGF group rats were treated with 18 μg·kg-1·d-1 NGF (total 7 times); NC group and COP group treated with the same dose saline. 90 min, 7 day, 14 day and 21 day groups of rats serum myelin basic protein (MBP) levels were monitored. The routine preparation of brain tissue frozen pathology slice, line HE and MBP immunohistochemical staining. Animal intelligence is assessed by Morris water maze experiment, in the 120 s in rats to determine correctly through the platform number less than 3 times DEACMP. RESULTS: All rats showed typical toxic after CO poisoning. Experimental group rats died 29, including COP death cases in the group, the model NGF group of 15, 14, mortality rates were 37.50%, 35.00% respectively. Morris water maze experiment results showed that the COP in the group 8 rats were judged to be delayed encephalopathy; model NGF group has 5 only be judged to be delayed encephalopathy; COP group rats serum MBP content increased significantly, model NGF group close to normal.Differences were obvious in poisoning after 7 days, 14 days.Pathological examination showed the COP group delayed encephalopathy rats in poisoning 90 min-21 d in hippocampus, subcortical neurons damage, such as myelin basic protein depigmentation pathological changes.The above pathological changes can be observed in each group, the COP group rats lesion severity is heavy, model NGF group was lighter. CONCLUSION: Mouse nerve growth factor can significantly reduce the incidence of delayed encephalopathy in rats, but can't reduce the mortality. Myelin basic protein (MBP) in the pathogenesis of delayed encephalopathy may play an important role.

Objective To investigate the clinical effects differences of three-port and single-port invasively combination laparoscopic cholecystectomy and appendectomy in the treatment of acute appendicitis complicated with gallbladder stone. Methods 110 patients with acute appendicitis complicated with gallbladder stones from August 2012 to August 2015 were randomly divided into control group (55 patients) with three-port laparoscopic operation and observation group (55 patients) with single-port laparoscopic operation;and the clinical indexes for operation related, operation overall satisfaction score of Brown, the VAS score of depression and anxiety before and after operation and postoperative complications of both groups were compared. Results The incision length of observation group was significantly shorter than control group (P< 0.05). The operative time of observation group was significantly longer than control group (P < 0.05). The operation overall satisfaction of Brown of observation group was significantly higher than control group (P < 0.05). The VAS score of depression and anxiety after operation of observation group was significantly better than control group and before operation (P<0.05). There was no signiifcant difference in the incidence of postoperative complications between 2 groups (P < 0.05). Conclusion Compared with three-port laparoscopic operation, single-port invasively combination laparoscopic cholecystectomy and appendectomy in the treatment of acute appendicitis complicated with gallbladder stone can efifciently decrease the incision length, improve the aesthetic degree and postoperative negative emotions and not lead to increased risk of postoperative complications.

The major goal of microbial ecology is to study the structure and function of complex micro-bial communities. New molecular biological techniques have been successfully applied to analyze mi-crobial community structure. However they do not provide information on the physiologic properties of the detected microorganisms. A new tool for structure-function analyses in microbial ecology, micro-autoradiography combined with fluorescence in situ hybridization (MAR-FISH) can be used to simul-taneously examine the phylogenetic identity and the specific activity of microorganisms within a com-plex microbial community at a single-cell level. This article reviews the principle, experimental steps of MAR-FISH technique. The application of this technique in study of the environmental microbial com-munity and function is also summarized.

Objective To investigate the relationship between transfusion transmitted virus (TTV)infection and neonatal hyperbilirubinemia,the effect of TTV infection on the liver function, and analyse the feature of nucleotide sequences in TTV ORF1.Methods Serum TTV DNA,which were from 58 neonates with high direct bilirubin(DB,including 5 with hepatitis Syndrome),92 ones with high indirect bilirubin(IB),and 85 normal ones,was detected using a nested polymerase chain reaction technique(nPCR),electropherosis and sequence analyse,and serum alanine amniotransferase (ALT)was determined in all neonates.Results In DB neonates,TTV DNA were detected in 7 neo- nates(12.1%,including 3 neonates with hepatitis syndrome);in IB and normal ones,1 neonate had positive TTV DNA(1.1% and 1.25),respectively.Even if there were point mutations in Guangdong's TTV,the homology of Guangdong's TTV(GD1-9)and Japanese TTV(N22)ranged from 87.1%～97.8% at nucleotide level.Conclusion TTV infection may be one of important pathogenesis resulting in neonatal hyperbilirubinemia and liver damage in such patients.Guangdong's and Japanese TTV isolates had the same genotype,some gene mutations maybe increase the pathogenicity in TTV.
