OBJECTIVETo compare therapeutic effects of clavicular hook-plate fixation and modified Weaver-Dunn surgery combined with clavicular hook-plate fixation in treating Tossy type III acromioclavicular joint dislocation.

METHODSForty-one patients with Tossy type III acromioclavicular dislocation treated by operation were retrospectively analysis from January 2012 to January 2014. The patients were divided into clavicular hook-plate fixation group (group A) and modified Weaver-Dunn surgery combined with clavicular hook-plate fixation (group B) according to surgical procedures. In group A, there were 15 males and 6 females aged from 17 to 51 years old with an average of (31.60 ± 12.58) years old, preoperative Constant-Murley score was 40.25 ± 9.80, and treated with clavicular hook-plate fixation. In group B, there were 13 males and 7 females aged from 18 to 48 years old with an average of (29.40 ± 11.27) years old, preoperative Constant-Murley score was 41.45 ± 8.81, and treated with modified Weaver-Dunn surgery combined with clavicular hook-plate fixation. Operative time, blood loss, imaging changes before and after operation, postoperative complications were compared; Constant-Murley score at 3, 6 and 12 months after operation were evaluated.

RESULTSIn group A, operative time was 40.50 ± 24.36) min, blood loss was (75.30 ± 30.36) ml; In group B, operative time was (60.10 ± 23.55) min, blood loss was (100.70 ± 40.12) ml. Twenty-one patients in group A were followed-up from 12 to 18 months with an average of (14.8 ± 3.1) months; 20 patients in group B were followed-up from 12 to 14 months with an average of (13.6 ± 1.5) months. There were no significant differences in operative time, blood loss and follow-up time between two groups. Complications were in six patients of group A and 3 patients of group B, and there were no significant meaning between two groups. At 6 months after operation, Constant-Murley score in group A was 88.85 ± 4.23, 92.15 ± 3.82 in group B; and had significant meaning between two groups (t = -2.56, P = 0.022 < 0.05). While there were no differences in Constant-Murley score in other times.

CONCLUSIONBoth of clavicular hook-plate fixation and modified Weaver-Dunn surgery combined with clavicular hook-plate fixation are effective operative methods for the treatment of Tossy type III acromioclavicular dislocation. Clavicular hook-plate fixation has advantage of less trauma, while modified Weaver-Dunn surgery combined with clavicular hook-plate fixation could reconstruct coracoclavicular ligament more stronger, clavicular hook plate could take out earlier, also improve shoulder joint function earlier.

Men(59.1%, 3 099/5 249) were more than women (40.96%, 2 150/5 249). The largest number of deaths was in the age of 75-84 years (42.56%, 2 234/5 249). The number of cases with combined above five diseases was 4 552(86.72%, 4 552/5 249). The top three causes of deaths of elderly inpatients in medical department from 2012 to 2019 were cardiocerebrovascular diseases (27.21%, 1 428/5 249), malignant tumor (25.74%, 1351/5 249) and respiratory system diseases (22.10%, 1160/5 249). From 2012 to 2015, the top three causes of deaths were malignant tumor, cardiocerebrovascular diseases and respiratorysystem diseases. From 2016 to 2019,the top three causes of deaths were cardiocerebrovascular diseases, malignant tumor, and respiratory system diseases. The most common cause in cardiocerebrovascular diseases of death was coronary heart disease (51.47%,735/1 428), cerebrovascular disease (43.70%,624/1 428),and hypertension(4.34%, 62/1 428). Among the patients with malignant tumor death, first cause of death waslung malignant tumor (37.53%, 507/1 351), the others in turn were gastric carcinoma (11.10%,150/1 351) and intestinal cancer (11.10%,150/1 351). Among the patients with respiratory system diseases, first cause of death was pulmonary infection (69.66%,808/1 160), the others in turn were chronic obstructive pulmonary disease (15.43%, 179/1 160) and interstitial lung disease (5.09%, 59/1 160). Conclusions:The average age of elderly inpatients in medical department is (78.52 ± 7.82) years. The death age of male is less than that of female, and the number is slightly more than that of female. The top three causes of deaths of elderly inpatients in medical department are cardiocerebrovascular diseases, malignant tumor, respiratorysystem diseases. From 2012 to 2015 the first cause of deaths is malignant tumor. From 2016 to 2019, the cardiocerebrovascular diseases rise to the first.

Objective To analyze the epidemic situation of human brucellosis in Qinghai province,in order to provide a theoretical basis for prevention and treatment of brucellosis.Methods Five counties in Qinghai province(Ping'an county,Haiyan county,Tianjun county,Dari county and Henan county) were selected as monitoring counties in 2010,and three or four townships were selected as monitoring points in each county.People aged 7 to 60 close contacted with livestock were monitored.The methods of rose bengal plate agglutination test(RBPT) and standard tube agglutination test (SAT) were used for serological testing.Brucellosis diagnosis was based on Brucellosis Diagnostic Criteria(WS 269-2007).Results A total of 2021 high-risk subjects from 5 counties were examined for brucellosis,and 76(by RBPT) of them were serologically confirmed with a positive rate of 3.76％ (76/2021),SAT positive 15 persons,the average positive rate was 0.74％ (15/2021).The number of infections was 15 cases,average prevalence was 0.74％(15/2021 ),and 3 new eases were discovered.The seasonal peak of incidence was from February to June.Most of the eases were reported dealing with slaughtering and fur processing.Conclusions The main reasons for epidemic rise are that the source of infection is not completely clear and weak awareness of self-protection in employees.So we must strengthen the quarantine,do surveillance on occupational groups and epidemic reporting work,carry out vocational training,strengthen publicity and education,and enhance the protection awareness.Thus brucellosis epidemic will be effectively controlled.

Objective To investigate the effects of female sex hormones in cow's milk on metabolism of blood lipid in young male rats.Methods Forty-eight male Sprague-Dawley rats aged 21 days old were assigned randomly to 4 groups,each containing 12 rats,and fed with quantitative milk from postpartum cow,milk from pregnant cow,commercial whole milk and artificial milk,respectively.Serum total cholesterol (TC),triacylglyeriol(TG),high-density lipoprotein cholesterol (HDL-C),low-density lipoprotein cholesterol (LDL-C) and urinary creatinine (Cr) were determined with automatic biochemical analyzer.Serum progesterone(P4)and urinary free estriol(UFE3) were determined with immunochemiluminometric assays after all rats were killed at 53 days old.SPSS 13.0 software was used to analyze the data.Results Total estradiol and P4 were 1 189.66 pmol/L,833.98 pmol/L,588.17 pmol/L,286.48 pmol/L and 9.76 nmol/L,10.18 nmol/L,2.83 nmol/L,0.92 nmol/L in milk from pregnant cow,commercial whole milk,milk from postpartum cow and artificial milk groups,respectively.Serum TC were respectively(1.78?0.29) mmol/L,(1.94?0.20) mmol/L,(2.10?0.28) mmol/L and (2.11?0.22) mmol/L in pregnant milk,commercial whole milk,postpartum milk and artificial milk groups,and TC in pregnant milk group was lower than that in postpartum milk group or artificial milk group(P0.05).Conclusion Milk from pregnant cow may reduce serum TC in young male SD rats,which may be related to the conjoined effect of estradiol and P4.

The microbial transformation of buflomedil by Cunninghamella blakesleana AS 3.153 was studied, as well as a microbial model which can be used to mimic metabolism of buflomedil in mammal was established. Experiments were conducted to screen the capabilities of four strains of Cunninghamella species to transform buflomedil, in which C. blakesleana AS 3.153 was selected for a preparative biotransformation. Furthermore, the microbial model was established based on the transformation condition optimization. The parent drug and its metabolites produced by C. blakesleana AS 3.153 were detected by liquid chromatography-mass spectrometry method and three metabolites were identified while two of them were new found metabolites. Two major metabolites, para-O-desmethyl buflomedil and 12-C-oxidated buflomedil, were isolated by semi-preparative HPLC. Based on the comparison between different species, the microbial transformation of buflomedil by C. blakesleana AS 3.153 is more similar to the metabolism of buflomedil in human and Beagle dog than that in rat.

Abstract: Objective To investigate the epidemiological characteristics of pathogens causing bloodstream infection in hematology patients during treatment and to compare the effects of allogeneic hematopoietic stem cell transplantation (HSCT) on them, so as to provide evidence for the diagnosis and treatment of bloodstream infection. Methods A total of 292 cases with bloodstream infection in hematology wards of the PLA General Hospital were collected from 2017 to 2021, which were divided into HSCT group and N-HSCT group according to whether performed HSCT or not. The epidemiological characteristics and influence of pathogenic bacteria in blood stream infection were analyzed and compared between the two groups. Results A total of 362 strains of pathogenic bacteria were collected from 292 cases, including 106 strains in HSCT group (84 cases) and 256 strains in N-HSCT group (208 cases). Bloodstream infections were more common in acute myeloid leukemia (130/392, 44.52%), followed by non-Hodgkin's lymphoma (74/292, 25.34%). The rate of once bloodstream infection in HSCT group was higher than that in N-HSCT Group, but the rate of twice bloodstream infections in N-HSCT group was higher. Gram-negative Bacilli were the most common pathogens (56.08%), with Escherichia coli being absolutely dominant (109/362, 30.11%), followed by Klebsiella pneumoniae (39/362, 10.77%). Coagulase-negative staphylococci (CoNS) (107/362, 29.56%) were the most common Gram-positive cocci. The detection rate of fungi in HSCT group (10/106, 9.43%) was significantly higher than that in N-HSCT Group (3.52%). The drug resistance rate of the common pathogenic bacteria was at a high level, and there was a certain proportion of multi-drug resistant strains (except for Pseudomonas aeruginosa). The resistance rates of CoNS to penicillin, gentamicin, moxifloxacin, clindamycin and rifampicin in HSCT group were higher than those in N-HSCT Group. The resistance rate of Escherichia coli to piperacillin/tazobactam, cephalosporins and etapenem in HSCT group was significantly higher than that in N-HSCT group. Conclusions The pathogens of blood stream infection in hematology patients are complicated and various. It is difficult for clinical diagnosis and treatment to detect multiple infections and multiple pathogens. HSCT patients have a higher risk of fungal bloodstream infection and more multi-drug resistant strains detected. Therefore, the identification of bloodstream infection and multi-drug resistant strains associated with HSCT patients should prompt surveillance.

In order to investigate whether cytokine-induced killer (CIK) cells can induce apoptosis of bcr-abl(+) K562 cells, apoptosis of K562 cells and CEM cells induced by CIK cells, etoposide or camptothecin was detected with flow cytometry DNA assay. RT-PCR showed that K562 cells expressed the bcr-abl fusion gene, K 562 cells, K562 cells/etoposide or K562 cells/camptothecin groups showed no sub-G(1) peak. K562 cells/CIK cells group showed sub-G(1) peak (38.1%). CEM cells showed no sub-G(1) peak. CEM cells/camptothecin or CEM cells/etoposide groups showed sub-G(1) peak (23.5% or 32.3% respectively). CEM cells/CIK cells group showed sub-G(1) peak (45.4%). Etoposide or camptothecin did not induce apoptosis of K562 cells. CIK cells induce apoptosis of K562 cells. Bcr-abl fusion gene prevented apoptosis induced by etoposide or camptothecin, but did not prevent apoptosis induced by CIK cells. This property may support the observed adoptive immunologic effect of allogeneic bone marrow transplantation and donor lymphocyte transfusions of CML case relapsing after allogeneic bone marrow transplantation.

This study was aimed to evaluate the proliferation-associated antigen Ki-67 expression in diffuse large B cell lymphoma (DLBCL) and its clinical significance. The Ki-67 expression and its correlation with prognosis in 50 patients with DLBCL treated with rituximab plus CHOP (R-CHOP) between January 2008 and December 2010 were analyzed retrospectively. The results indicated that there was no significant relationship between Ki-67 expression and clinical features, including age, sex, staging, B symptoms, LDH level, IPI, extranodal site involvement, presence of bulky tumors (>10 cm in diameter), bone marrow involvement, GCG nor GCB type, or response to first line treatment. The median survival was 50 months and 15 months in low Ki-67 expression group (<85%) and in high Ki-67 expression group ( ≥ 85%) respectively. The overall survival (OS) and progress-free survival (PFS) in low Ki-67 expression group were obviously longer than that in high Ki-67 expression group (P = 0.001; P = 0.027). In univariate analysis, the clinical factors associated with OS included Ann Arbor staging and Ki-67 expression. The clinical factors associated with PFS included Ann Arbor staging. IPI and Ki-67 expression. In multivariate analysis. The Ki-67 expression level was an independent prognostic factor for OS (HR = 4.90; 95% CI, 1.456-16.511; P = 0.0103). It is concluded that Ki-67 expression level seems to be an effective marker for evaluation of DLBCL prognosis.
