Objective To observe and scale knee joint space of the patients who suffered adults' Kaschin-Beck disease (KBD) in Shangzhi City of Heilongjiang Province in order to acquire basic knowledge for upcoming intervention trial. Methods Clinical test was proceeded in adults aged above 40 in Guanghui Village of Shangzhi City in 2007. In typical patients, bilateral knee X-ray was taken and knee joint space was scaled. Three points were chosen on inner and outer epicondyle of each knee and results were recorded. Results There were 307 peoples over the age of 40 in the village. Two hundred eighty-two accepted clinical test, in a rate of 91.9%. Eighty out of 282 suffered KBD, accounting for 28.4%. When the patients' condition became more serious, measurements from flank, middle, inside points on outer epicondyle of joint space presented a narrowing trend [degree Ⅰ: (5.85±0.17), (4.84±0.17), (4.36±0.18)mm; degree Ⅱ: (5.11±0.43), (4.24±0.34), (3.48±0.28)nun; degree Ⅲ: (3.59± 0.78), (3.10±0.56), (2.14±0.62)mm; Fflank,middle,inside= 6.547,5.372,10.302, all P < 0.05], but those on inner epicondyle of joint space did not[degree Ⅰ:(3.66±0.17), (3.47±0.17), (3.73±0.18)mm; degree Ⅱ:(3.55± 0.34), (3.54±0.29), (4.35±0.35)mm; degree Ⅲ: (3.19±0.72), (3.92±0.66), (4.51±0.72)ram; Finside,middle,flank= 0.351,0.356,1.883, all P > 0.05]. Joint space < 5.00 mm were found in 618, among which 363 were measured on inner epieondyle, obviously greater than those measured on outer epicondyle of joint space(255), the difference being statistically signifieant(χ2=9.59, P<0.05). Conclusions Adult cases of KBD occur in Guanghui Village. Knee joint space of adult patients narrows obviously, the more serious, the narrower, especially occurring more obviously on outer epicondyle, but frequently on inner epicondyle.

Objective To observe the curative effect of low melocular weight heparin(LMWH) on the hypercoagulability in acute Kawasaki disease(KD).Methods Forty-six patients were diagnosed KD.Twenty-two cases out of all KD patients whose serum concentration of whether platelet(PLT) or fibrinogen(FIB) was significantly increased or who were found thrombus in their coronary artery by ultrasonic Doppler were treated with LMWH by subcutaneous injection once every day for 7-10 days.All the patients were divided into 2 groups accor-ding to whether using LMWH or not:H group(using LMWH) and NH group(no using LMWH).It were detected before and after treatment that included thrombin time(TT),activated partial thromboplastin time(APTT),international normalized ratio(INR),FIB,plasma mucosity,erythrocyte sedimentation rate(ESR),hematocrit(HCT) and situation of haemorrhage.Results 1.Before treatment,PLT and FIB of patients in H group were significantly higher than those in NH group(Pa

ObjectiveTo observe the projections from respiratory neurons of medulla oblongata to the motor neuron pool of phrenic nerve in rat. MethodsBy using horseradish peroxidase (HRP) retrograde tracing technique after injecting HRP into phrenic nerve, retrograde labelled neurons were found in C3-C5 segment. Then, HRP was injected into the area where the phrenic motor neurons occupied, retrograde labelled neurons were found in medulla oblongata. ResultsPhrenic motor neurons locate in the C3-C5 segment ipsilaterally, occuping the intermediate portion of anterior horn and appearing typical motor neurons. Retrograde labelled neurons were found bilaterally in medulla oblongata, the neurons were located in nucleus retroambigualis (RNA), ventramedial area to nucleus retrofacialis (NRF). ConclusionThe phrenic motor neurons may receive direct projection of respiratory neuron in medulla oblongata, the projecting neurons are distributed in RNA and NRF area.

Chronic prostatitis (CP) is a common disease in men, and its pathogenesis remains to be clarified. The precise regulation of cytokines is involved in all types and all stages of CP. The interaction of inflammation, inflammatory cells and cytokines leads to the development and progression of CP. With further understanding of the immunological and molecular biological mechanisms of the disease and more inflammatory cytokines used in its detection, it is of special significance to apply cytokines in the classification and treatment of CP. This review outlines the roles of cytokines in the pathogenesis of CP, particularly chronic pelvic pain syndrome (CPPS), their relationship with CP, and their significance in the classification and diagnosis of CP/CPPS.

Objective To examine the composition and distribution of animal reservoir of plague in Quanzhou city, Fujian province, and so as to accumulate basic data for making the plague prevention and control measures. Methods Rodents were captured by cages in six monitoring spots of Quanzhou city between 2000 and 2009. Then rodents and flea species were identified. Rats liver and spleen homogenates were detected of plague F1 antigen by reverse indirect hemagglutination test (RIHA); rats serum were detected of plague F1 antibody by indirect hemagglutination test (IHA). ResultsA total of 26 264 rodents were captured between 2000 and 2009.Rattus norvegicus and Rattus flavipectus were dominant species, which were accounted for 45.97％ (12 074/26 264)and 32.01％(8407/26 264), respectively. The account of Rattus flavipectus captured between 2005 and 2009 was (26.99 ± 2.46)％ and (37.03 ± 3.79)％ between 2000 and 2004. The difference was statistically significant (t =4.97, P ＜ 0.05). Total rodent densities was (6.86 ± 1.44)％, including(5.36 ± 1.83)％ in mountains and (6.81 ±1.66)％ in coastal areas, respectively, and the difference was not statistically significant(t =1.01, P ＞ 0.05). Total flea index and flea infection rate of rodents were 1.39 ± 0.34 and (35.90 ± 5.34)％, respectively. Xenopsylla Cheopis index was 1.20 and free flea index was 0.009. Flea infection rate was (32.36 ± 0.96)％ between 2005 and 2009, which was lower than (39.44 ± 0.39)％ between 2000 and 2004(t =2.76, P ＜ 0.05). ConclusionsThe major rodent species found in Quanzhou city is Rattus norvegicus. Xenopsylla Cheopis is the dominant flea species.Spreading of plague among Rattus is not found.

OBJECTIVETo explore the effect of Shenqi Fuzheng Injection (SFI) on gene expression profile of liver tissue with metastatic carcinoma in mice.

METHODSTwenty liver metastatic carcinoma model mice were established by splenectomy after their spleens were injected with 0.2 mL colon cancer C26 cell strain oncocyte liquid, then they were randomly divided into the model group and the SFI group. Starting from the 5th day after modeling, mice in the model group and the SFI group were given via intraperitoneal injection once every other day with physiological saline and SFI respectively. All the mice were sacrificed at the 15th day and the gene profile of metastatic liver carcinoma tissue in the two groups were screened by whole genome chip technique.

RESULTS(1) The model establishing successful rate reached 100%; (2) Gene expression showed that as compared with the model group, in the SFI group, 123 genes were up-regulated, with 52 of them registered to Ensemble, while only one gene was down-regulated and registered to Ensemble was none.

CONCLUSIONSFI plays its role of anti-tumor mainly by upregulating several relative genes to promote apoptosis of tumor cells and stabilizing chromosomes.
