Objective To assess the application value of color Doppler ultrasound (CDU) in the diagnosis of osteofascial copmarttnent syndrome (OCS) of forearm.Methods A total of 19 patients highly suspected of or diagnosed as acute OCS of forearm underwent CDU in comparison with clinical diagnosis and therapy.The echoes of muscles,the diameter and change of flow Doppler spectra of radial artery and ulnar artery were observed.Results In 16 patients of OCS,most of the forearm muscle swelled (enlarged more than 1/2-2/3 area) with the muscle echo enhanced unevenly:the textures were unclear or disappeared;and fluid or hematom appeared in muscles;and the diameter of radial artery and ulnar artery diminished.The flow Doppler spectra of radial artery and ulnar artery appeared as bid-diastolic whole inverse wave,bip-,unid-,uniph-wave,unip-,unid-uniph-wave and venous like Doppler wave.Resistance index increased.Conclusion The acute OCS of forearm has some sonographic characteristics.CDU can be used to diagnose the acute OCS of forearm.

Objective To evaluate the risk of plague occurrence via surveying and analyzing indoor rat density and flea index in natural villages having previous plague experience. Methods During August to September 2007, 30 natural villages experiencing previous plague were selected based on the surveillance data, and then all households were coded with numbers and 20 households in each village were randomly selected via computer. Cages and sticky papers were set in 600 selected households to capture rats and fleas. Rat density, flea prevalence, flea index and median were estimated. Results One hundred thirty-three Rattus flavipectus and 33 Suncus murinus were caught and averaged rat density was 2.8 rats per one hundred cage. nights (166/6000), the median was 5 rats each village. One hundred and one mice infected fleas, flea prevalence on rats was 60.8% (101/166), 296 Xenopsylla cheopis and 48 Leptopsylla segnis were collected. Rat flea index was 2.1 fleas per rat (344/166). A total of 315 dissociated flea was caught, average dissociated flea index was 0.026 fleas per sticky paper (315/11888). The median was 5.5 dissociated fleas per village. Of dissociated fleas, Ctenocephalides felis felis (205) and Xenopsylla cheopis (103) accounted for 97.8% (308/315). The proportion for species of the rat flea and the dissociated flea was different(Fisher test: P < 0.01). The rat flea was significantly associated with the rat density(r = 0.68, P < 0.01), but the dissociated flea was significantly associated with neither the rat density(r = -yield than fried wheat batter(χ2 = 5.59, P < 0.05). Conclusions In these villages having previous plague experience of Lianghe County, Rattusflavipectus was dominant species of indoor rats, Xenopsylla cheopis and Ctenocephalides felis felis were dominant species of rat flea and dissociated flea, respectively. Mengsong, Bangdu, and Tangjiatun village had potential risk of plague emergence.

BACKGROUD: It is not consistent on whether melatonin correlates with the adolescent idiopathic scoliosis(AIS) demonstrated by the domestic and foreign scholars.OBJECTIVE: To study the pathogenesis of AIS and its correlation with melatonin.DESIGN: A nonrandomized age-matched controlled study screened with two tests.SETTING: The Second Department of Orthopaedics, Haikou People' s Hospital.PARTICIPANTS: The experiment was completed in the Second Department of Orthopaedics, Haikou People' s Hospital. Totally 8 198 in-school students.from over 10 schools of towns in Haifu District, 4 423 males and 3 775 females, aged 7 to 16 years were surveyed.METHODS: Forty-two adolescents who have been diagnosed with AIS were selected and 50 healthy age-matched adolescents were selected as controls. Melatonin was assayed with the radioimmunology and the data were processed statistically.MAIN OUTCOME MEASURES: The levels of serum melatonin in the two groups.RESULTS: The serum melatonin of the preadolescents below 10 years old in AIS group, especially of females, was less than that of adolescents in the control group, with significant differencein statistics.CONCLUSION: The serum melatonin correlates with pathogenesis of AIS.

BACKGROUND: Removal of immunosuppressants in patients with recurrent tumor in long-term following organ transplantation is always a hot controversial point in academic circles. To further elevate clinical efficiency, people began to invent new immunosuppressant and studied immune efficiency of various immunosuppressant component. They tried to reduce the application of cyclosporin A (CsA).OBJECTIVE: To analyze the CsA safe withdrawal of a case of kidney recipients, at 18 years after renal transplantation, who developed bladder carcinoma and renal pelvic carcinoma at 11 years and 18 years after transplantation, respectively. METHODS: After identified diagnosis, we performed transurethral resection of bladder tumor (TURBt) and total nephroureterectomy merobladder excision. Pathologic examination revealed grade Ⅰ-Ⅱ of bladder and renal pelvic transitional cell carcinoma. After the operation, patient was treated with immune suppression program of CsA withdrawal gradually in 12 days.Within 12 days, 5 mg CsA was decreased every 3 days, and complete withdrawal was done at 12 days. The dosage of azathioprine tablets and prednisone acetate tablets was not changed. Serum creatinine levels were rechecked every 3 days during drug withdrawal, and blood pressure, urine volume, physical symptom of patients and ultrasound of transplanted kidney were observed.RESULTS AND CONCLUSION: During the three months of CsA withdrawal, the blood creatinine levels were from 65 to indicated that the CsA gradually withdrawal of a case of kidney recipients after renal transplantation, who developed transitional cell carcinoma and was performed transurethral resection of bladder tumor (TURBt) and total nephro- ureterectomy merobladder excision, was safe. No tumor relapse or diversion was found.

Objective To identify and rename one strain stored in National Center for Medicine Culture Collections ( CMCC) and used for tracheitis vaccine production. Methods The test strain CMCC (B)29108 and the type strain DSM30007T were cultured on NA medium. Characteristics in morphology, physiology, biochemistry and fatty acid profile were compared between the two strains. Phylogenetic analysis was based on 16S rRNA and rpoB gene sequences, together with the DNA-DNA hybridization assay. Results A Comparative analysis of a partial sequence of the 16S rRNA gene sequence revealed that the CMCC( B) 29108 strain was closed to the Acinetobacter species and showed the highest similarity with the type strain Acinetobacter baumannii DSM30007T. Moreover, the CMCC(B)29108 strain was highly similar to type strain DSM30007T in morphology, physiology, biochemistry and fatty acid profile. On the phylogenetic tree based on 16S rRNA and rpoB gene of all Acinetobacter members, the CMCC(B)29108 strain steadily clustered into one independent branch only with the DSM30007 T strain with a DNA-DNA hybridization value of 100%. Conclusion The CMCC(B)29108 strain that is one of the strains used for the production of tracheitis vac-cine should be assigned to the species of Acinetobacter baumannii based on its phenotypic, phylogenetic and chemotaxonomic characteristics.

OBJECTIVETo study the simple infection and super/co-infection of HAV-HEV, HGV in patients with viral hepatitis.

METHODSUsing EIA method to detect anti-HAV IgM, HBV serum markers, anti-HCV IgM, anti-HDV IgM, anti-HEV IgM, anti-HGV IgM in viral hepatitis patients with different clinical types.

RESULTSSeventy-three percent patients (154/210) had HBV infection markers, twenty-nine percent patients (61/210) had HAV infection marker, eight percent patients (17/210) had HCV, HDV infection markers, ten percent patients (21/210) had HEV infection and seven percent patients (15/210) had HGV infection. Only nine percent patients (20/210) had viral hepatitis serum markers negative. In all clinical types, sixty-one percent patients had only one type hepatitis virus infection, thirty-two percent patients had two types of hepatitis virus super/co-infection, six percent patients had three types of hepatitis virus super/co-infection. Super/co-infection often occurred in patients who had cirrhosis or hepatic failure.

CONCLUSIONHBV and HAV infection is very common in viral hepatitis patients, whereas HCV, HDV, HEV and HGV infection is relatively low; double super/co-infection of HAV-HEV, HGV frequently occurs in severe patients with viral hepatitis.
