Objective To analyze the stability of chromosome variant ratio of three available transformed corneal cell lines. Methods Chromosome specimens of transformed cells including human corneal epithelial cells(HCE),bovine corneal endothelial cells(BCE) and rabbit corneal epithelial cells(RCE) were prepared by a direct method using regular Giemsa staining. Chromosomes of cells in metaphase were counted under the microscope. Then, the variant ratio of chromosomes and their nuclear types were analyzed. Results The chromosome numbers were 56 to 65, 27 to 34 and 74 to 88 for HCE, BCE and RCE, respectively. Chromosome numbers in the three commonly used and transformed corneal cell lines were changed in comparison to their parent tissues. Conclusion Genotyping study may provide important information for using HCE、BCE、RCE in functional studies.

ObjectiveTo analyze the relationship between clinical characteristic pathology and prognosis in infant with intra-abdominal solid tumor.MethodsFifty-two infants(less than 1 year old) with abdominal solid tumor from Apr.1998 to Feb.2007 in Shanghai Children's Medical Center and from Jan.2001 to Feb.2007 in Shanghai Xinhua Hospital were reviewed.The history of these children were reviewed.Features and clinical pathology of these children with their prognosis were analyzed and followed up by telephones and children return visit records from 5 months to 8 years.ResultsLess than 1 month,7 cases;1 month to 1 year old,45 cases.Teratoma 23 cases(44.23%),neuroblastoma 9 cases(17.31%),nephroblastoma 6 cases(11.54%),hepatoblastoma 5 cases(9.62%),epithelioid hemangioendothelioma of the liver 3 cases(5.77%),congenital mesoblastic nephroma 3 cases(5.77%),fusiform cell epithelioid hemangioendothelioma of pancreas 1 case(1.92%),hamartoma of the liver 1 case(1.92%),retroperitoneal small cell malignant tumor 1 case(1.92%).Benign:malignant=1:1.Among the benign tumor,male:female=1:1.Among the malignant tumor,male:female=2.33:1.0.All children were treated with tumor resection,and combined with chemotherapy for those whose tumors were malignant.ConclusionsAmong infant abdominal solid tumors,teratoma and neuroblastoma are much more than other tumors.The cases of benign tumors are almost as much as the malignant tumors.The benign tumors did not have sex differences,and had good prognosis after surgical resection.However,in malignant tumors,the incidence rate of male is obviously higher than female.Completely resection of those malignant tumors with chemotherapy would get little incidence of recrudescence and low case fatality rate.Early diagnosis and early treatment play an important role in prognosis.

ObjectiveIn an attempt to clarify the usefulness of combined nerve and muscle biopsy in the diagnosis of neuromuscular disease when compared with traditional sural nerve biopsy.Methods Fifteen biopsies of superficial peroneal nerve (SPN) and peroneus brevis muscle ( PBM ) by one incision performed within one neurological clinic were reviewed.All patients had peripheral neuropathy while 3 of them had myopathy clinically.The diagnostic significance of SPN and PBM biopsies were classified into 3 grade: essential,helpful,no value.ResultsOf 15 SPN and PBM biopsies,7 showed essential pathological findings whichreachedthe etiologicaldiagnosis, including 5definitevasculitis, 1inflammatory demyelinating polyneuropathy and 1 amyloid neuropathy.Five biopsies are helpful for etiological diagnosis,including demyelinating neuropathy,mild inflammation,and microvascular lesion,et al.Three biopsies are of no value for etiological diagnosis which only have nonspecific change such as type 2 fiber atrophy,neurogenic atrophy and axonal degeneration et al. Finally,SPN and PBM biopsies made the definite etiological diagnosis possible in 12 patients.ConclusionsSPN and PBM biopsy improved the yield of specific pathological and etiological diagnosis of neuropathy and myopathy such as vasculitis and amyloidosis with minor trauma and side effect.Further clinical and pathological studies will be necessary for a better practice of combined nerve and muscle biopsy.

Objective To study the effects of salt sensitivity on evolution of blood pressure and develope- ment to hypertension from adolescents to youth.Methods A baseline survey was carried out in 4623 adolescents aged 6-15 years old in Hanzhong rural area in 1987,310 of them were recruited for determination of salt sensitiv- ity using the tests of oral saline load and furosemide sodium-volume depletion.Salt sensitivity (SS) were diag- nosed in 101 while 209 subjects as no-sah sensitivity (NSS).This cohort of adolescents were followed up for av- erage 18 years.Results The response rate for this cohort of adolescents was 71.9%.At the end of follow up period,BP in subjects with baseline SS was higher in youth than that in NSS (SBP:122.9?13.1 vs 117.3?12.4, P

Objective To investigate the effect of intraocular injection of mixed crystalline in vivo on survival of retinal ganglion cells(RGCs)after optic nerve cut.Methods Twenty Long-Evens rats were divided into normal control,and 7 day,14 day,and 21 day groups after optic nerve was cut off.There were 5 eyes in each group.Mixed crystallin(1x10~(-4)g/L)and isotonic saline solution were injected into the vitreous of fight eye and left eye respectively.The number of RGCs was counted 7,14 and 21 days after optic nerve cut.Results The density of RGCs declined clearly 7 days after optic nerve cut.In the group with crystallin injection,the density of RGCs declined to 71%,32% and 15% of the control group repec- tively,much higher than that of the controls on days 7,14 and 21 after optic nerve was cut off(P

OBJECTIVETo provide inspiration and ideas for clinical treatment of coronary heart disease (CHD) by data mining technology based frequency analysis and cluster analysis of medical records, prescriptions and herbs in treating CHD by distinguished veteran doctors of traditional Chinese Dedicine (TCM).

METHODSTotally 386 medical cases were retrieved from Wanfang Data, Chinese Scientific Journals Database (VIP medical information resources system, China National Knowledge Infrastructure (CNKI), and Typical Collections of Medical Cases by Contemporary Distinguished Veteran Doctors of Traditional Chinese Medicine. They input into database trimmed after unified standard. Medication laws of CHD by distinguished veteran doctors of TCM were analyzed using frequency analysis and cluster analysis, and so on.

RESULTSDistinguished veteran doctors of TCM frequently used top ten herbs in treatment of C D as Salvia miltiorrhiz , Ligusticum wallichii, Trichosanthes kirilowi, Pinellia ternat, Angelica sinensis, Poria coco stragalu , Panax ginseng, Allium macrostemon, and Radix Ophiopogonis. Cluster analysis summarized that there were 16 herb pairs commonly used, 7drug assemblies consisting of 3 herbs and 5 drug assemblies consisting of multiple herbs.

CONCLUSIONSDistinguished veteran doctors of TCM mainly used herbs assemblies capable for invigorating Pi to resolve phlegm, and promoting qi and activating blood circulation in treating CHD. Meanwhile, they concurrently used herbs combination of nourishing Xin and tranquilization, and regulating yin and yang.
