Neonatal intrahepatic cholestasis caused by Citrin deficiency(NICCD) is one of phenotypes of Citrin deficiency.It's an autosomal recessive disorder which was mainly seen in East Asia,including China.Case of NICCD was reported firstly by Japanese in 2001.In south area of China,the morbidity of NICCD is higher than that in north area of China.Most of the patients with NICCD has benign prognosis.Symptoms resolve within the first year of life,thus making a diagnosis difficult after this time.But few of patients will develop liver failure,even be fatal to life.Early diagnosis,regular follow-up and proper management may improve the prognosis.

The evaluation on clinical efficacy of traditional Tibetan medicine (TTM) is an important scientific subject during the development of TTM. Firstly, the authors introduced the current situations and problems in evaluation on clinical efficacy of traditional Tibetan medicine both at home and abroad in this study. Secondly, they compared the similarities and differences between TTM and traditional Chinese medicine (TCM) in evaluation on clinical efficacy, define their differences in details but not in nature, and proposed that TTM could selectively learn TCM's experiences in clinical research and build a specific methodology system for evaluation on clinical efficacy according to its own characteristics. Thirdly, they discussed the methodological challenges in evaluation on clinical efficacy of TTM, including the pending clinical research guidelines and disease diagnosis standards according to its own characteristics. Finally, they propound some suggestions for promoting the evaluation on clinical efficacy of TTM, including the comprehensive application of multiple research methods, overall research-based evaluation on efficacy of TTM complex intervention and selection of accepted and objective outcome indexes for efficacy evaluation.

Side population (SP) cells are highly enriched for stem cell activity and characterized by their ability to efflux the vital dye Hoechst 33342, because they express the ATP binding cassette (ABC)-dependent transporter ABCG2. SP cells can be selected from main population using flow cytometric analysis. Currently SP cells have been isolated from many tissues and organs. SP cells of different origins have some common characteristics. This article introduces the classifications, surface marker, and characteristics of SP cells.

strains that could produce raw starch-digesting glucoamylase were isolated from soil and mildewed rice.The highest raw starch-digesting glucoamylase activity strain named OR-1 was identified as Rhizopus.sp.The raw starch-digesting glucoamylase activity of the strain is 90U/mL.Through UV and NTG mutagenesis,the raw starch-digesting glucoamylase activity raised to 200U/mL and 325U/mL respectively.The RDA were 70% and 65% respectively.

Objective To analyze international research status and research focus of neural stem cells.Methods Using bibliometric analysis,the paper analyzed the international neural stem cells research documents in web of science database by analysis tools such as Thomson Data Analyzer.Research status on neural stem cells was analyzed including the distributions of years,countries,institutions and currently hot topics of international research on neural stem cells were emphatically analyzed.Results Researches on neural stem cells have developed rapidly in the recent 10 years.Main research countries include the America,China,Japan,and European Union etc.The key research topics in the field of international neural stem cells included neural stem cells proliferation,differentiation,gene transcription,gene expression in basic research and research on neural stem cells transplantation therapy including Parkinson' s disease,spinal cord injuries,stroke,Alzheimer disease,Huntington disease etc.Conclusions Neural stem cells research has become a hot topic for international researchers,and inspiriting progress has been made.There are still many issues that need to he further explored.

Objective To investigate the effect of nobiletin,a citrus polymethoxy flavonoid,on hepatocarcinoma Heps in mice and to explore its immunological mechanism.Methods Mice tumor models were made by transplantation of Heps hepatocarcinoma cell strain.The tumor mass was weighed to calculate the tumor-inhibitory rates.The whole cellular immunity was observed by delayed type hypersensitivity(DTH).MTT assay was used to detect the proliferation of T and B lymphocyte,and the activities of cytotoxic T lymphocytes(CTL) and natural killing cells(NKC) were measured by lactate dehydrogenase(LDH) releasing method.Results Nobiletin could markedly inhibit the growth of hepatocarcinoma Heps(solid tumor).The decreased DTH in hepatocaricinoma mice was enhanced significantly,and T and B lymphocyte proliferation were increased by nobiletin.Meanwhile,the killing activities of CTL and NKC were promoted obviously.Conclusion Improvement of the immune function may be a vital route of nobiletin in inhibiting the proliferation of hepatocarcinoma Heps in mice.

Objective To correctly analyze the positive results of electrocardiogram treadmill exercise test (TET) and improve the level of diagnosis of CHD Methods Two hundred and fifty eight patients with chest pain underwent TET and CAG; the case history and different clinical parameters were collected (1) Clinical data of the true positive group and the pseudo positive group were compared and underwent a statistic analysis (2) Clinical data of the female positive group were compared and underwent a statistic analysis Results The number of females in the pseudo positive group was larger than in the true positive group;The number of patients with typical chest pain, hyperlipidemic history, history of smoking, family history of CHD was smaller than in the true positive group;In the pseudo positive group,the changes of ST segment were mainly in Ⅱ, Ⅲ and aVF The number of extent of changes of more than 0 2 mV and with angina induced during exertion in pseudo positive group was smaller than in true positive group In females, under 60 years, the number of ST segment changes of resting ECG and left ventricular hypertrophy was larger in pseudo positive group than in true positive group The difference was significant Conclusion The factors including sex, typical chest pain,risk factors of CHD, the location and extent of ECG changes and angina induced following exertion should be combined to analyze the positive results of TET

Objective To evaluate the application value of ureteroscopy in the diagnosis and treatment of ureteral obstruction.Methods Clinical data of 52 cases of non-calculous ureteral obstruction treated by ureteroscopy were analyzed retrospectively.Results Of 35 cases of ureteral stricture,19 cases of routine dilatation,13 cases of balloon dilatation,and 3 cases of ureteroplasty were accomplished under ureteroscope.Holmium laser resection was employed in 13 cases of ureteral polyps.Conversions to open surgery were required in 3 cases of ureteral cancer,and an ureteroplasty was carried out in 1 case of retrocaval ureter.Complications included 2 cases of ruptured mucous membrane or urethral false passage and 1 case of ureteral perforation.Conclusions Ureteroscopy can clarify the etiology of ureteral obstruction and offer corresponding treatment.
