Objective:To analyze the clincial characteristics and laboratory findings of patients with neurobrucellosis (NB).Methods:Using retrospective analysis, clinical diagnosed patients with NB from June 2016 to February 2019 in Heilongjiang Agricultural Reclamation Bureau General Hospital were selected to analyze the general characteristics, clinical symptoms, laboratory examination results [white blood cell (WBC), hemoglobin(Hb), c-reactive protein (CRP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), total protein (TP), albumin (ALB), cerebrospinal fluid routine and biochemical, serum tube agglutination test (SAT), blood culture and cerebrospinal fluid culture of Brucella] , diagnosis and treatment effect. Results:A total of 25 patients were diagnosed with NB, including 19 males and 6 females, with an average age of (41.7 ± 14.2) years old, ranged from 11 to 70 years old. The main clinical symptoms were fever, headache, joint pain, vomiting and sweating, which accounted for 92.0% (23/25), 88.0% (22/25), 76.0% (19/25), 64.0% (16/25), and 64.0% (16/25), respectively. Positive neck ankylosis and mumbness of lowerlimbs were both 9 cases (36.0%), and mental disorders were 7 cases (28.0%). In 25 patients with NB, the WBC increased in 5 cases (20.0%), Hb decreased in 4 cases (16.0%), CRP increased in 13 cases (52.0%), ALT and AST both increased in 6 cases (24.0%), TP decreased in 21 cases (84.0%); SAT was positive in 25 cases (100.0%), cerebrospinal fluid SAT positive in 7 cases (28.0%); and blood culture was positive in 2 cases (8.0%). Cerebrospinal fluid changes were mainly manifested in 14 cases (56.0%) of chloride reduction, 13 cases (52.0%) of gluose reduction and 19 cases (76.0%) of protein increase. In 25 patients with NB, 17 cases were treated with doxycycline + rifampicin + ceftriaxone, 7 cases with etimicin + rifampicin + ceftriaxone, and 1 case with doxycycline + rifampicin + piperacillin sulbactam. After 6 to 12 months follow-up, 21 cases recovered well, whereas mild sequelae were observed in 4 patients.Conclusion:Clinical features of NB are hetorogeneous, and nerurological symptoms and cerebrospinal fluid examination are of great value in the diagnosis of NB.

Objective To explore the effects of reoperation on treatment of recurrent pelvic endometriosis(RPEM).Methods The clinical data of 47 cases of RPEM reoperation in our hospital from April 2005 to October 2010 was investigated,and the efficacy was analyzed compared with the first operation data.Results The cases of painful nodules was significantly different between reoperation group and the first operation group(28 vs 14,x2 =8.436,P =0.004 ).There was significant difference on laparoscopic surgery cases between reoperation group and the first operation group (25 vs 40,x2 =7.259,P =0.007 ).The operation time in reoperation group was significantly longer than that in the first operation group( [ 106.4 ±41.0] min vs [ 78.4 ± 26.4 ] min,t=3.995,P ＜ 0.01 ),and the amout of intraoperative hemorrhage in reoperation group was more than that in the first operation group ( [ 143.2 ± 118.3 ] ml vs [ 70.6 ± 68.1 ] ml,t =3.660,P ＜ 0.01 ).However,there was no significant difference on symptoms,cyst location and clinical stage between these two groups(P ＞0.05).Conclusion Due to the pelvic adhesion would be dense and extensive in RPEM,it should be carefully dissected during reoperation.At the same time,the operator should pay attention to the anatomical location and try to restore the normal anatomy of the pelvic organs and physiological state,and try to reduce postoperative adhesions.Complete removal of the lesions is the key to improve the treatment effect and prevent recurrence and reoperation.

AIM To study the expression, purification and activity assay of recombinant mouse protein kinase CK2? subunit from Escherichia coli. METHEDS The recombinant plasmid containing mouse protein kinase CK2? subunit cDNA constructed successfully was transformed into Escherichia coli BL21 (DE3) and specifically induced by IPTG. The recombinant mouse CK2? subunit was sequentially purified by DE 52, P11 phosphocellulose and Heparin Sepharose chromatography. The purified recombinant protein was analysed by SDS PAGE. RESULTS One protein with molecular mass of 42 ku was overexpressed by inducing ITPG. The recombinant protein was composed of approximately 30 6% of the total bacterial proteins. From 278 mg soluble proteins, the yield of the CK2? protein was 4 7 mg. SDS PAGE analysis of the purified recombinant protein showed only one band in agreement with native mouse CK2? subunit. The recombinant mouse CK2? and ? subunits were mixed at the same molar ratio. The produced CK2 holoenzyme displayed full activity. The characteristics and functions of reconstituted CK2 holoenzyme were consistent with those of the given native CK2. CONCLUSION The recombinant protein is mouse protein kinase CK2? subunit.

Objective To analyze the diagnostic value of fluorescence polarization assay (FPA) for human brucellosis.Methods From April 2013 to August 2014,240 positive sera of brucella patients were collected as case group and 287 normal sera as control group in Heilongjiang Agricultural Reclamation Bureau General Hospital.Four milliliters of venous blood were withdrawn for separation of serum.Fluorescence polarization assay was used and the consistency,sensitivity and specificity were compared with those of four classical serological methods,including rose bengal plate agglutination test (RBPT),standard tube agglutination test (SAT),Coomb's test and cysteine test.Results The results of FPA were complied with those of the four conventional serological methods,Kappa ≥ 0.75.The sensitivity of FPA (89.17％) was higher than that of RBPT (87.08％),SAT (85.00％),Coomb's (74.17％) and cysteine test (75.83％).The specificity of FPA (94.08％) was higher than that of RBPT (89.90％) and Coomb's (81.53％),but lower than that of SAT (98.95％) and cysteine test (99.30％).Conclusion FPA can be used as a laboratory diagnostic method for human brucellosis,which is worthy to be widely used.

MicroRNAs (miRNAs) are a class of non-coding RNA molecules that regulate gene expression after transcription and participate in various pathophysiological processes in the skin. In recent years, it has been reported that changes in miRNA expression profiles are related to some inflammatory skin diseases. For example, miR-203, miR-146a and miR-21 are upregulated in psoriatic lesions, miR-155 and miR-146a are upregulated in atopic dermatitis lesions, miR-21, miR-223, miR-142-3p and miR142-5p are upregulated in allergic contact dermatitis lesions; however, miR-146a and miR-155 are downregulated in peripheral blood of patients with systemic lupus erythematosus, and miR-223 is downregulated in dermatomyositis lesions. This review summarizes relationships of miRNAs with the occurrence and development of some inflammatory skin diseases.

Objective To investigate the differents of rapid enzyme-linked immunosorbent assay(IELISA) and the traditional serological methods in diagnosis of human brucellosis.Methods Brucella antibody was detected by IELISA,rose bangel plate test (RBPT),standard agglutination test (SAT),Coomb's test and cysteine test of serological methods in 430 confirmed and suspected patients and 300 healthy controls during the same period.The consistency was analyzed between IELISA and other tests.Results Positive rates of patients were significandy higher than those in healthy controls (IELISA:83.49％ vs.0;RBPT:86.97％ vs.0;SAT:76.27％ vs.0;Coomb's:65.58％ vs.0.02％;and cysteine test:67.91％ vs.0,x2 =535.05,412.47,437.66,339.22,489.49,all P ＜ 0.01).Positive consistency rates between IELISA and other tests were 87.19％,79.39％,71.59％ and 76.60％,the highest was between IELISA and RBPT,the lowest was between IELISA and Coomb's.Conclusions Brucella antibody is detected conveniently,quickly,and accurately by the joint application of RBPT and IEHSA,which provides important technical support for prevention and control of brucellosis.It is worthy of application extensively.

A method for simultaneous determination of 12 kinds of chlorinated disinfection byproducts (DBPs) in drinking water was developed based on liquid-liquid extraction gas chromatography equipped with electron capture detector (GC/ECD).The procedural standard calibration was adopted to eliminate the interference of different matrix.The method detection limits for 12 DBPs were 0.08-0.21 μg/L and the entire analytical procedure was finished in 21.50 min.The recoveries were in the range of 80.9%-115.7% and the relative standard deviations (RSD) were between 0.9% and 9.9% at different concentration levels (5 and 50 μg/L) in tap water and surface water.The correlation coefficients for all 12 kinds of DBPs were greater than 0.99 in the linearity range of 0.5-200 μg/L.The method was applied to determine DBPs in drinking water and source water.This method was rapid and competent for detection of volatile DBPs in drinking water.

Previous studies have suggested that various kinds of inflammatory factors can influence the formation and development of tumor cells.Researche has shown that gallbladder cancer is closely linked with local inflammation,which is a risk factor for the development of gallbladder cancer.It is widely known that cholecystitis is closely correlated with gallstones,and that bile obtained from patients with gallbladder cancer contains a large variety of bacteria,such as Salmonella typhi,Helicobacter,and Escherichia coli.It is proposed that the gallbladder may be the result of the joint action of inflammation with the bacterial flora.Similarly,the inflammatory “tumor infiltrating lymphocyte” (TIL)can be observed in the tumor and its surrounding tissues,and may also play a role in tumor growth and metastasis.However,detailed mechanisms about the relationship between inflammation and gallbladder cancer is still not clear.No specific anti-inflammatory drugs for gallbladder cancer have been developed. In the near future,anti inflammatory drugs may play a more important role in gallbladder cancer prevention and treatment.
