OBJECTIVETo investigate the epidemiological characteristics, clinical manifestations, diagnosis, and treatment of Brucella orchitis, so as to provide reliable evidence for the prevention and treatment of the disease.

METHODSWe conducted retrospective statistical analyses on the medical records of 48 outpatients and 21 inpatients with Brucella orchitis.

RESULTSBrucella orchitis was diagnosed in 6.67% of the male patients with brucellosis (69/1 034). The disease exhibited typical epidemiological features, with a higher incidence rate among those in frequent contact with sheep and elderly people, in the period from April to July, and in the areas with sheep husbandry. All the Brucella orchitis patients had such local symptoms as testicular pain and swelling, more frequently involving both testes, and other most common symptoms included fever, chills, sweating, and painful joints. Based on IIEF-5, 45 of the patients suffered from severe erectile dysfunction, with their reproductive function temporarily affected in the course of the disease. Misdiagnosis easily occurred in the early stage of the disease. Therapeutic options mainly included doxycycline hydrochloride and rifampicin, administered orally or intravenously, which could effect a cure, though relapse might occur in some cases.

CONCLUSIONBru- cella orchitis has distinct epidemiological characteristics, with clinical manifestations of testicular pain and swelling. Though a transient disease, it affects the reproductive function of the patient before cured. It can be treated by combined oral and intravenous medication, with painkillers or ice bags for testicular pain and swelling.

Objective To investigate the expression and secretion of mice DNaseI gene plasmid transfected into bone marrow (BM-MSCs) mesenchymal stem cells. Methods The plasmids of mouse DNaseI gene had been transfected into the BM-MSCs of mice by liposomes. The expression of DNaseI gene in the BM-MSCs was detected by western blotting and the DNaseI activity was measured by DNA-methyl green substrate colorimetry. Results About 30% BM -MSCs were transfected with mice plasmid DNaseI gene, DNaseI was expressed in the transfected BM-MSCs and active DNaseI could be detected in the supernatant of cell culture. Conclusion The mice DNaseI gene plasmid can be transfected into mice BM -MSCs by liposomes and DNaseI gene can be expressed by the transfected BM-MSCs and active DNaseI can be secreted. This may provide potential target for the treatment of SLE.

OBJECTIVETo explore clinical outcomes of posterior malleolar fractures with medial-extension type through posterioromedial and posteriorlateral incision.

METHODSFrom January 2008 to January 2011,25 patients with posterior malleolar fractures with medial-extension type were treated by hollow lag screw. Among them, 15 patients were treated through posteromedial incision,including 9 males and 6 females,aged from 21 to 67 years old with an average of 48.1 +/- 1.3; there were 5 cases with type A, 6 cases with type B and 4 cases with type C,according to Denis-Weber classification. Ten patients were treated by through posterior-lateral incision,including 6 males and 4 females, aged from 23 to 64 years old with an average of 46.9 +/- 1.5; there were 3 cases with type A, 5 cases with type B and 2 cases with type C,according to Denis-Weber classification. Operation time, blood loss, length of incision, times of X-ray exposure and complications of two groups were recorded and compared, Baird-Jackson effective evaluation were applied for evaluate clinical outcomes.

RESULTSAll patients were followed up from 12 to 49 months with an average of 20.6 months. There were significant differences in operation time, blood loss, times of X-ray exposure and complications between two group (P < 0.05). While there was no obvious meaning in clinical outcomes between two groups (P > 0.05).

CONCLUSIONTreating posterior malleolar fractures with medial-extension type through posteromedial approach can expose and fix fracture under direct vision, has advantages of shorter operation time, less X-ray exposure and blood loss, is a good choice of surgical approach.

Objective To evaluate the changes of the left atrial function in patients with old myocardial infarction(OMI) by strain rate imaging(SRI). Methods The velocity of the left atrial lateral wall and atrial septum was measured by SRI in 30 patients with OMI(OMI group) and 25 normal subjects (control group). Left atrium passive eject volume index(LAPEVl) and left atium active eject volume index (LAAEVI) were measured using Simpson method. Results ①Compared with the control group, the velocity of the left atrium was reduced obviously in ventricular systole and early ventricular diastole in OMI group(P<0.05) ,but was increased in late ventricular diastole(P<0.05). ②Compared with the controls, LAAEVI was increased significantly in OMI group, but LAPEVI was decreased signicantly(P <0.001). Conclusions SRI could be used to evaluate the left atrial function accurately in patiens with OMI.

f strain rate in left atrial wall, which is prior to the remodeling geometry of left ventrieular, could be detcted by STI more sensitively than by SRI.

This study was to improve the way for selecting ura5 mutants of Cryptoccocus neoformans Cap59 capsule-deficient strains.They were induced by Diethyl Sulfate. Ura5 mutants were screened by 5-fluoroorotic acid counter selection method. Using the new method, we obtained two ura5 mutants of Cryptoccocus neoformans Cap59 capsule-deficient strain.A easy method that was used to screen ura5 mutants of Cryptoccocus neoformans has been established.

In recent years (2007 to 2011),although the overall number of rabies cases in China has decreased,there is evidence of emerging or re-emerging cases in regions without previous rabies cases or with low incidence of rabies.To investigate the origin and the factors affecting the spread of rabies in China,specimens were collected from 2007 to 2011 from provinces with emerging and re-emerging cases and tested for the presence of the rabies virus.Positive specimens were combined with sequences from GenBank to perform comparisons of homology and functional sites,and to carry out phylogenetic analyses.Out of these regions,five provinces had 9positive specimens from canine and cattle,and 34 canine or human specimens were obtained from previously high-incidence provinces.Complete sequences of G gene were obtained for these samples.Homology of the sequences of these 43 specimens was 87％-100％ at the nucleotide level and 93.7％ -100％ at the amino acid level.These G gene sequences were combined with reference sequence from GenBank and used to construct a phylogenetic tree.The results showed that 43 specimens were all assigned to China clade I and clade Ⅱ,with all specimens from emerging and re-emerging areas placed within clade I.Specimens isolated from Shanxi and Inner Mongolia in 2011 were distinct from previously-isolated local strains and had closer homology to strains from Hebei,Beijing and Tianjin whereas new isolates from Shanghai were tightly clustered with strains isolated in the 1990s.Finally,Shaanxi isolates were clustered with strains from adjacent Sichuan.Our results suggest that the rabies cases in emerging and re-emerging areas in China in the last 5 years are a consequence of the epidemic spreading from of neighboring provinces and regions experiencing a serious epidemic of rabies.

Objective To investigate the current situation of the prevention and contml of iodine deficiency disorders(IDD)in Hubei Province,SO as to provide a policy.making basis for controlling work of IDD. Methods Using the method of proportional population sampling(PPS),30 eounties were seiected in Hubei Province.In each selected county,1 primary school was chosen.In every primary school,40 pupil8 aged 8～10 years were selected to examine thyroid size,intelligent quotient(IQ),and salt iodine contents at their home.In the selected pupils,2 boys and 2 girls were chosen to determine their urinary iodine contents in each age grouD.Twenty pupils in the above school and 5 housewives ileal"to this school were tested in health education questionnaire. Results The median of salt iodine was 30.1 mg/kg,and the rate of comsuming qualified iodized salt was 96.2% (1154/1200).The rates ofchild goiter were 6.5%(78/1200)by palpation and 4.1%(49/1200)by B ultrasound.The median of urinary iodine Was 358.4μg/L and mean of the IQ was 105.3±14.4.The rate of qualified scores of both students and housewives Was 25.5%(153/600)、90.7%(136/150).Conclusions The current Bituation of iedine nutrition is good.The goal of eliminating IDD has been achieved in Hubei Province.
