The diatom test has been used as a main diagnotic method of drowning.but itis doubful and even is considered valueless by some authors nowadays for it hasbeen proved by Niles Forged(1983)that the diatoms found in the internal organsof submerged corpses might be inspired into the body during fhe lifeWe believed that the diagnosis of drowning might be made by examining lungchlorophyll(a)of planktons with spectro-fluorophotometer qualitatively and quantitatively.According to our experimental stuudiesIt is confirmed that this method could be used for the diagnosis of drowning.Mean while two cases submerged in water were investigate.and the causesof deathwere diagnosed correctly.It is concluded that the examination of the lungchlorophyll(a)of planktoms could be used as a reliable diagnostic method infore nsic practice

Objective To investigate the effects of early partial body weight supported stand training on depression and balance function after massive cerebral infarction.Methods 40 patients with depression after massive cerebral infarction were divided into 2 groups,training group(n=20) and control group(n=20).All patients were treated with routine medication and rehabilitation.The patients of the training group also received partial body weight supported stand training in addition.They were assessed with the Hamilton depression scale(HAMD) and the Berg balance scale(BBS) before and after the treatment.Results After 8 weeks of treatment,the scores of HAMD and BBS of the training group had improved significantly more than those in the control group(P<0.05).Conclusion Early partial body weight supported stand training on the patients with depression after massive cerebral infarction may obviously improve balance function and reduce the degree of depression.

Objective To evaluate the influence of amphetamine-type stimulants on serum rapid plasma reagent (RPR) tiler and negative conversion rate of RPR in patients with syphilis. Methods Thirty-six patients with syphilis who took amphetamine-type stimulants (ATS) were recruited in this study together with 44 patients with syphilis who never took ATS and 30 normal human controls. Benzathine benzylpenicillin was given intramuscularly to all patients at a dose of 2 400 000 unit per week for 3 weeks. RPR and treponema pallidum particle agglutination (TPPA) assay were performed before treatment, 3, 6, 9 and 12 months after the therapy. Radioimmune assay and ncphelometry were used to detect the serum level of IgG, lgM and IgA. The capability of peripheral blood mononuclear cells (PBMCs) to product interferon-T (IFN-γ) and interleukin-4 (IL-4) was evaluated with ELISA. Results Before treatment, RPR titcr was significantly lower in the stimulant-taking group than in the non-taking group (χ2 = 14.93, P < 0.05). The negative conversion rates were 5.56%, 16.67% and 52.78% in stimulant-taking group 6, 9 and 12 months after the treatment, respectively, significantly lower than those in the control group (all P < 0.05). As for the serum level of IgG, IgM and IgA, there was no significant difference among the stimulant-taking group, non-taking group and normal control group (all P > 0.05). The capability of PBMCs to product IFN-γ was highest in the stimulant-taking group, followed by the non-taking group and normal control group (all P < 0.05). No significant difference was observed in the capability of PBMCs to produce IL-4 between the stimulant-taking group and non-taking group, but a significant increment was noted in these patients compared with the normal human controls (all P < 0.01). Conclusion Amphetamine-type stimulants could reduce serum RPR titer and negative conversion rate of RPR in patients with syphilis, likely by impairing cellular immunity of patients.

Objective To investigate the effect of early screening and intervention on congenital hypothyroid-ism.Methods Thyroid stimulating hormone (TSH),three thyroid stimulating hormone (T3 )and thyroid hormone (T4 )were screened in 72h after birth,and thyroid ultrasound examination.All the patients were treated with the treat-ment of the left -to -thyroid hormone,0 -6 months medication dose 25 -50g/d,6 -12months medication dose 50 -100g/d,1 -3months medication dose 75 -100g/d.Serum TSH was reviewed every three months in the age of 1 years, 2 -3 years old every six months to review the serum TSH.Results The mean value of TSH in children with congeni-tal hypothyroidism was (68.7 ±15.3)mU /L.The mean value of T4 was (42.4 ±13.1)nmol/L.100 cases of chil-dren,including 38 cases of primary congenital hypothyroidism,transient congenital hypothyroidism in 62 cases.Ultra-sound examination showed primary congenital hypothyroidism were developmental abnormalities,and abnormal absence of a total of 18 cases (47.4%),Abnormal blood flow in 15 cases (39.5%);No abnormalities were found in the ultrasound examination of the transient congenital hypothyroidism.Before treatment,TSH in children with congenital hypothyroidism was significantly higher than that in the control group[(68.7 ±15.3)mU /L vs (4.6 ±1.1)mU /L], T4 was significantly lower than the control group[(42.4 ±13.1)nmol/L vs (124.4 ±45.5)nmol/L],the differences
were statistically significant (t =22.867,16.058,all P <0.05);After treatment,the TSH of the children was signifi-cantly decreased[(5.3 ±1.1)mU /L vs (68.7 ±15.3)mU /L],and the T4 was significantly increased[(114.5 ± 35.4)nmol/L vs (42.4 ±13.1)nmol/L],compared with before treatment,the differences were statistically significant (t =41.331,19.101,all P <0.05 ),but compared with the control group,there were no significant differences between TSH and T4 (all P >0.05).After 1 -3 years follow -up observation,children with Gesell development scale test showed that children with adaptability,large movements,fine movements,language and social skills to reach the normal level.Conclusion Early screening and treatment of the patients with congenital hypothyroidism is beneficial to the rehabilitation of the patients with congenital hypothyroidism.

The hospital information structure, which is made up of various medical business systems, is suffering from the problems of the "information isolated island". Medical business systems in the hospital are mutually isomerous and difficult to become a whole. How to realize the internal barrier-free interaction of the patients effective medical information in the hospital and further to complete the area sharing of patients longitudinal diagnosis and treatment information has become a question having to be solved urgently in the process of healthcare informatization. Based on the HL7 standard, this paper refers to the IHE technical framework, expounds the overall structure of the interaction in the hospital internal and area sharing of medical information with the medical information exchange platform. The paper also gives the details of the whole process of the complete display of the discrete patient health information using Portal technology, which is saved in the business systems in different hospitals. It interacts internally through the information exchange platform and at last stores the information in the regional clinical data repository (CDR).

Objective To ascertain the role of NF?B and relationship among TGF?1,caspase-3 and apoptosis in CsA-induced nephrotoxicity.Methods Sixty-four wistar male rats were randomly divided into 4 groups:Vehicle,PDTC,CsA and CsA + PDTC group.The animals were daily subcutaneously injected either with CsA(15 mg/kg)or vehicle/PDTC(100 mg/kg).Four weeks later,BUN,serum creatinine,NAG and urine routine were examined.The kidneys were processed for light microscopy,immunohistochemistry and TENUL.Results A rat model of CsA-induced nephrotoxicity was established.CsA group showed significant increase in BUN,SCr and urine NAG compared with the controls,whereas CsA + PDTC group did not.Apoptosis is observered by TUNEL and the expressions of NF-?B,TGF-?1,caspase-3 increased significantly in CsA group compared with conrtol group.Whereas,both the apoptosis and the expressions of these proteins significantly decreased in rats treated with PDTC.Conclusion Apoptosis is induced in the CsA-induced chronic nephrotoxicity.Inhibition of NF-?B activation blockaded apoptosis and ameliorated CsA-induced chronic nephrotoxicity.The results suggest that NF-?B plays important roles in the progression of chronic CsA nephrotoxicity.

The widely application of the radio knife alleviates the patient's pain and improve the medical quality.The radio knife is high frequency power equipment based on the theory that electricity concentrates on the skin.It can directly cut the tissue,homeostasis and cauterize.The safety requirement of this equipment is very strict because unsafe operation will burn the tissue,cause temporal unaware hurt and even endanger the patient's life.If the safety support system is imperfect,disastrous loss or medical conflict will be caused.Users must be cautious in using and familiar with the safety and protection of the radio knife.[Chinese Medical Equipment Journal,2008,29(2):96-98,104]

Objective To explore the regulation mechanism of X box binding protein 1 (XBP1)signal transduction pathway for TNF-α and effective approach in ischemia/reperfusion (I/R) injury of liver transplantation for short hairpin RNA (shRNA) interference used to gene therapy in liver graft.Methods Male Sprague-Dawley rats were divided into three groups: the cold ischemia transfection group (CIT), the in vivo transfection group (IVT) and the control group. Experiments of orthotopic liver transplantation were performed by two cuff method. The rats in CIT were perfused with XBP1-shRNA plasmid (pSIXBP1) during cold ischemia phase, those in IVT received the equivalent volume (2 ml) of pSIIRAK 4 after portal vein inoculation, and those in the control group were not subjected to any treatment. Rats were killed at 60 or 180 min after restoring reperfusion of hepatic portal vein.Histopathological damage degree of graft liver was observed by light microscope. The expression levels of XBP1 gene and protein were detected by RT-PCR and Western blotting. The activities of NF-κB and the serum TNF-α level were detected by ELISA. Results All the indexes including the degree of histopathological damage, the expression levels of XBP1 mRNA and protein and the TNF-α level were significantly decreased in CIT as compared with IVT and control group (P＜0. 05). However,there was no significant difference in NF-κB activity among the three groups (P＞0. 05). Conclusion The role of XBP1 pathway in TNF-α gene regulation and that of NF-κB pathway in rat liver I/R injury are two relatively independent aspects, and the depression of XBP1 expression with XBP1 shRNA through portal vein perfusion during cold ischemia phase could effectively alleviate graft hepatic I/R

Objective To detect the expression of Livin,an apoptosis-inhibiting protein,and Smac,an apoptosis-promoting protein,in basal cell carcinoma (BCC) lesions.Methods Skin specimens were obtained from the lesions of 80 patients with BCC and normal skin of 30 human controls.Immunohistochemical SP method was used to detect the pmtein expression of Livin and Smac in these specimens.Chi-square test was conducted to compare the expression rate of Livin and Smac protein between the lesional and control specimens.The relationship between the protein expression of Livin and Smac in BCC was analyzed by Spearman correlation coefficients.Results The expression rate of Livin protein was significandy higher (77.50％ vs.3.33％,x2 =49.04,P ＜ 0.001),while that of Smac protein was statistically lower (46.25％ vs.100％,x2 =26.47,P ＜ 0.001),in BCC than in the control specimens.No significant difference was observed in the expression rate of Livin or Smac protein between nodular ulcerative and pigmented BCC specimens (75.41％ vs.80.00％,x2 =0.001,P ＞ 0.05; 47.54％ vs.40.00％,x2 =0.28,P＞ 0.05) or between nodulocystic and pigmented BCC specimens (73.58％ vs.80.00％,x2 =0.03,P ＞ 0.05; 45.28％ vs.40.00％,x2 =0.13,P ＞ 0.05).There was a negative relationship between the protein expression of Livin and Smac in BCC lesions (r =-0.432,P ＜ 0.01).Conclusion The upregulated expression of Livin and downregulated expression of Smac may be invoved in the occurrence and development of BCC.

OBJECTIVE: To investigate diagnosis method and treatment experience of jugulare glomus tumor (JGT) and carotid body tumor (CBT). METHOD: Retrospective analysis. Clinical materials from 4 patients at one genealogy with JGT and CBT were collected. The clinical features, radiological characteristics, surgical methods and prognosis were assessed. The proband suffered from left JGT and left CBT, her younger sister had right CBT as well as her younger female cousin had bilateral CBT and right JGT, her older male cousin had bilateral CBT and left JGT. These JGT and CBT in four patients were resected under general anesthesia after preoperative ultrasound, CT or CT angiography (CTA), MRI, and digital subtraction angiography (DSA) examination as well as preoperative vascular embolization. RESULT: The surgery was uneventful in four cases, and there was no hemiplegia or deaths. All patients were followed up for 2 years to 29 months without recurrence. Six months after operation, the hoarseness also disappeared in the older male cousins but did not improve significantly in younger female cousin. The younger female cousin get right peripheral facial paralysis 1 year after surgery and her temporal bone CT indicated a right JGT. CONCLUSION It is very important to assess JGT and CBT by Ultrasound, CT, CTA, MRI and DSA. Surgical resection is the first optional treatment for JGT and CBT. Blood loss can be reduced by preop erative vascular embolization. Serious complications could be avoid by operating under microscope, which can supply a clear surgical field and make the surgeon to protect the large blood vessels and nerve.
