Objective To investigate the current status of multidrug-resistant organism (MDRO) infection in the general surgery department of a tertiary first-class hospital, and understand the efficacy of comprehensive intervention measures.Methods Targeted monitoring on MDROs was implemented among patients who were hospitalized in a general surgery department for>48 hours between March 2015 and October 2016, comprehensive intervention measures were taken since January 2016.MDRO infection before and after intervention was compared.Results Between March 2015 and October 2016, a total of 6 406 hospitalized patients were monitored, 155(2.42%) developed MDRO infection.The most common infection sites were abdominal cavity(hydrops, bile) (n=76, 49.03%) and surgical site (n=43, 27.74%).MDRO infection rate dropped from 2.79% (99/3 549) before intervention (March-December, 2015) to 1.96% (56/2 857) after intervention (January-October, 2016) (x2=4.612, P=0.032).There was no difference in MDROs between before and after intervention, the major were both Escherichia coli.Conclusion Comprehensive intervention measures can reduce the incidence of MDRO infection in the general surgery department of this hospital.

Objective To analyze the epidemiological features and influencing factors of human brucellosis in Qinghai province,and to provide scientific basis for prevention and control of brucellosis.Methods From 2006 to 2010,select the high incidence areas of brucellosis in Qinghai province and five counties(Henan,Dari,Tianjun,Ping'an and Haiyan counties) included in the “Central Subsidies to Local Public Health Special Fund Human Brucellosis Prevention and Control Projects” for the survey point,as well as high-risk employees from Qinghai Biological Pharmaceutical Factory were investigated.Combined with epidemiological questionnaire investigation [done according to the “National Human Brucellosis Surveillance Program(Trial)”],clinical symptoms and signs,confirmed human brucellosis patient were tested by intradermal allergy test,rose bengal plate agglutination test(RBPT) and standard tube agglutination test (SAT),in accordance with “Diagnostic Criteria and Principles of Management of Brucellosis” (GB 15988-1995) and“Diagnostic Criteria for Brucellosis” (WS 269-2007).Results Of 8368 serum samples detected,347 were RBPT positive,and the positive rate was 4.15％;5346 serum samples were tested by SAT,180 were positive,and the positive rate was 3.37％.In June 2009,112 employees in Qinghai Biological Pharmaceutical Factory were investigated on a follow-up survey,83 were RBPT positive,the positive rate was 74.11％; 58 were SAT positive,the positive rate was 51.79％.Eight of them were new cases and 4 were chronic brucellosis.Twenty five new cases were reported between 2006 and 2010.The peak incidence was from March to July.Most of the cases were herdsmen.ConclusionStrengthening animal quarantine,strengthening public education,and improving protection awareness,can effectively control the disease brucellosis.

OBJECTIVETo observe the impacts on skeletal fluorosis pain, joint motor dysfunction and urine fluoride excretion in the treatment with fire needle therapy, electroacupuncture and calcium carbonate D3.

METHODSThe randomized controlled trial was adopted. Ninety-five patients were randomized into a fire needle group (31 cases), an electroacupuncture group (33 cases) and a calcium carbonate D3 group (31 cases). In the fire needle group and the electroacupuncture group, Ashi points, Dazhui (GV 14), Geshu (BL 17), Quchi (LI 11), Hegu (LI 4), Xuehai (SP 10) points were selected and stimulated with fire needle and electroacupuncture separately, three times a week. In the calcium carbonate D3 group, calcium carbonate D3 tablets was prescribed for oral administration, 600 mg each time, twice a day. The duration of treatment was 2 months in the electroacupuncture group and calcium carbonate D3 group and 1 month in the fire needle group. VAS score, the range of motion (ROM) and urine fluoride value were compared before and after treatment in the patients of the three groups.

RESULTSAfter treatment, VAS value and ROM were improved significantly in the patients of the three groups (all P < 0.05), the difference was not significant in comparison of the three groups (all P > 0.05). After treatment, the urine fluoride value was increased significantly in the fire needle group [(7.89 +/- 3.61) mg/L vs (9.81 +/- 4.17) mg/L, P < 0.01] and was increased in the electroacupuncture group [(7.53 +/- 3.46) mg/L vs (8.97 +/- 4.21) mg/L, P < 0.05]. The difference was not significant in comparison before and after treatment in the calcium carbonate D3 group (P > 0.05).

CONCLUSIONThe fire needle therapy, electroacupuncture and calcium carbonate D3 all have the clinical value in the prevention and treatment of skeletal fluorosis and the difference in the therapeutic effect has not been discovered among them yet at present. But it has been found that the fire needle therapy and electroacupuncture display the active significance in the promotion of urine fluoride excretion.

Objective To measure the expressions of cytotoxity-related cytokines in CD8+memory T cell subsets of peripheral blood in patients with multiple sclerosis (MS) and further analyze the relationship between the cytokine levels and MS disease severity. Methods Four-color flow cytometry was employed to detect the proportion of CD8+ memory T cell subsets expressed perforin and granzyme-B in peripheral blood of patients with MS, with other neurological disorders (OND) and of normal control (NC) group. The expanded disability status scale (EDSS) was used to reflect the disease severity at the time of blood sampling. Results Patients with MS had a decreased proportion of effector memory CD8+ T (CD8+ TEM) cells and terminal TEM cells expressed granzyme-B as compared with NC group (P＜0.05). CD8+ TEM cells expressed granzyme-B and perforin were negatively correlated to the scores of EDSS in patients with MS (r=-0.493, P=0.027; r=-0.594, P=0.009). Conclusions CD8+ TEM may be involved in the MS-related CNS inflammatory immune response. The proportion of CD8+ TEM cells expressed perforin and granzyme-B can be used to reflect the pathological severity of MS lesions to some degrees.

OBJECTIVETo observe the meridian reaction in patients with hypertension, to explore the significance of meridian diagnosis.

METHODSSixty-six patients with hypertension received two different methods of meridian detection. Kang Wei Human Body Meridian Analysis and Diagnosis System was applied to detect the volt-ampere characteristic curve on the Yuan (source) point of the 12 meridians. Five minutes after the first examination, the traditional method of meridian detection was used to examine the meridian reactions, such as pressing pain, tuber and cord-like reactants along the 12 meridians at forearms, lower limb, head and back.

RESULTSThere were sixty-five cases of abnormal volt-ampere characteristic curve among sixty-six patients with hypertension. The number of cases about Kidney Meridian of Foot-Shaoyin and Bladder Meridian of Foot-Taiyang were both 28 with the highest abnormal rate being 43.1%; Using traditional method of meridian detection, there were 41 cases of abnormal meridian reactions, about 28 cases of Governor Vessel, with the highest abnormal rate being 68.3%.

CONCLUSIONThe abnormal meridian reactions exist in Governor Vessel, Kidney Meridian and Bladder Meridian in patients with hypertension. Therefore, this finding provides clinical evidence in meridian diagnosis.

OBJECTIVE: To find the mutation of disease-causing genes of sudden unexplained death syndrome (SUDS) in the young by whole exome sequencing in one case. METHODS: One SUDS case was found no obvious fatal pathological changes after conventional autopsy and pathological examination. The whole exome sequencing was performed with the Ion Torrent PGM™ System with hg19 as reference sequence for sequencing data. The functions of mutations were analyzed by PhyloP, PolyPhen2 and SIFT. A three-step bioinformatics filtering procedure was carried out to identify possible significative single nucleotide variation (SNV), which was missense mutation with allele frequency < 1% of myocardial cell. RESULTS: Four rare suspicious pathogenic SNV were identified. Combined with the analysis of conventional autopsy and pathological examination, the mutation MYOM2 (8_2054058_G/A) was assessed as high-risk deleterious mutation by PolyPhen2 and SIFT, respectively. CONCLUSION Based on the second generation sequencing technology, analysis of whole exome sequencing can be a new method for the death cause investigation of SUDS. The gene MYOM2 is a new candidate SUDS pathogenic gene for mechanism research.

OBJECTIVETo investigate the intervention effect of thalidomide on paraquat-induced acute lung injury in mice and its mechanism.

METHODSMale ICR mice were randomly allocated to negative control group (n = 30), thalidomide control group (n = 30), paraquat poisoning group (n = 30), 50 mg/kg thalidomide treatment group (n = 30), 100 mg/kg thalidomide treatment group (n = 30), and 150 mg/kg thalidomide treatment group (n = 30). The negative control group was intraperitoneally injected with the same volume of saline; the thalidomide control group was intraperitoneally injected with thalidomide (150 mg/kg); the paraquat poisoning group was intraperitoneally injected with diluted paraquat solution (22 mg/kg); each thalidomide treatment group was intraperitoneally injected with the same volume of paraquat solution (22 mg/kg) and was injected with thalidomide (50, 100, or 150 mg/kg) 1 h later. All mice were anesthetized and sacrificed at 1, 3, or 7 d after paraquat poisoning, and their lung tissue was collected. The levels of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and IL-6 in lung tissue were measured by double-antibody sandwich ELISA; the mRNA expression of nuclear factor-kappa B (NF-κB) was measured by RT-PCR; the protein expression of nuclear NF-kgr;B p65 was measured by Western blot. The pathological changes of lung tissue were observed under light microscope; the wet/dry ratio of the lung was calculated.

RESULTSCompared with the negative control group, the paraquat poisoning group had significantly increased levels of TNF-α, IL-1β, IL-6, NF-κB mRNA, and nuclear NF-κB p65 and wet/dry ratio of the lung (P < 0.05). Compared with the paraquat poisoning group, the thalidomide treatment groups had significantly decreased levels of TNF-α, IL-1β, IL-6, NF-κB mRNA, and nuclear NF-κB p65 and wet/dry ratios of the lung (P < 0.05), and the 150 mg/kg thalidomide treatment group showed the most significant decrease in the levels of TNF-α, IL-1β, IL-6, NF-κB mRNA, and nuclear NF-κB p65. The observation of pathological changes showed that the paraquat poisoning group had the most marked lung tissue damage at 3 d after poisoning, and the lung tissue damage was lessened in the thalidomide treatment groups.

CONCLUSIONThalidomide can reduce paraquat-induced acute lung injury and lung edema. The mechanism may include inhibition of NF-κB activation and expression and downregulation of TNF-α, IL-1β, and IL-6.
