To study the effects of exercise and weight control on bone mineral density (BMD) of girl athletes, dual X-ray and single X-ray absorptiometry were adopted to measure BMD; And serum Vitamin D3, estrogen, cholesterol and alkaline phosphatase levels of subjects were determined. Subjects were 63 students of two age groups (before puberty. 8-9 years old; after puberty: 15-16 years old, respectively) of sports and ordinary schools. The results showed that.. Exercise training is beneficial to increase BMD; Long term weight control had no effect on BMDof athletes in this study; Yet girl athletes after puberty with low estrogen levels had less BMD; Girl judo players with rapid weight loss had higher BMD as compared with the same aged nontraining students.

Objective To evaluate in vitro antifungal activity of tacrolimus combined with itraconazole or terbinafine against Exophiala dermatitidis (E.dermatitidis).Methods The minimum inhibitory concentrations (MICs) of itraconazole and terbinafine against 12 strains of E.dermatitidis were determined using the Clinical and Laboratory Standards Institute (CLSI) broth microdilution susceptibility method (M38-A2 Document).A broth microdilution checkerboard method was used to evaluate the in vitro antifungal activity of tacrolimus combined with itraconazole or terbinafine against E.dermatitidis.Results The MIC ranges of terbinafine and itraconazole against E.dermatitidis were 0.060-0.125 mg/L and 0.5-1 mg/L,respectively.The combination of tacrolimus with terbinafine showed synergistic inhibitory effects against 5 strains of E.dermatitidis,while the combination of tacrolimus with itraconazole revealed synergistic effects against 10 strains of E.dermatitidis.No antagonism was observed in either of the two combinations.Conclusion In vitro combination of tacrolimus with itraconazole or terbinafine can enhance the antifungal activity of itraconazole or terbinafine against E.dermatitidis.

In order to understand the distribution of schistosomiasis in mobile population in Guangxi zhuang Autonomous Region, field investigation was conducted in 19 endemic villages selected by cluster sampling. The mobile people who were older than 3 years old were investigated by questionnaire and indirect hemagglutination( IHA) , then the IHA-positive ones were detected by fecal examination. Meanwhile, a snail survey was carried out. The results showed that a total of 2 866 people were investigated , among which 1 380 came from 143 endemic areas. A total of 2 428 people were involved in IHA examination with a positive rate of 3.46% , and the rate of people from endemic areas were significantly higher than that of ones from non-endemic areas( P < 0.01). Sixty people were involved in fecal examination, and the results were all negative. An area of 899. 3 hm~2 was surveyed, and the snail area was 4.97 hm~2, while none of positive snails were found. It is suggested that the mobile population is the main risk factor for potential schistosomiasis transmission in Guangxi, and the surveillance on this population should be strengthened.

Fifty residual Oncomelania snail points were found in Guangxi Zhuang Autonomous Region from 1998 to 2009,and the snail area was 14.9 hm2.The residual snail area increased year by year with complex environment.

To analyze the clinical characteristics and drug resistance in patients with non-tuberculous mycobacteria (NTM) pulmonary disease in Changsha Central Hospital of Hunan Province in recent three years.
 Methods: The clinical data of 153 patients with NTM pulmonary disease, who were diagnosed in Changsha Central Hospital of Hunan Province from February 2014 to May 2017, were retrospectively analyzed. According to the concentration of drug sensitivity test, the patients were divided into a low concentration group and a high concentration group. The status of drug sensitivity and drug resistance were examined.
 Results: Among 153 patients, 79 patients (51.63%) were male, 74 patients (48.37%) were female. The mean ages were (60.27±19.46) years. The NTM pulmonary disease mainly occurred in the individuals with bronchiectasis, and the course of disease was long (mean 7.8 years). The clinical symptoms were not specific and mostly misdiagnosed as pulmonary tuberculosis (92.81%). Mycobacterium avium-intracellulare (56.21%) and mycobacterium chelonae-abscess (20.92%) were the majority. The drug-resistance rate of the first-line and second-line anti-tuberculosis drugs was high. The majority was resistant to more than eight drugs, 38.56% patients in the low concentration group were resistant to total drugs, and 25.49% patients in the high concentration group were resistant to total drugs.
 Conclusion: The NTM pulmonary disease is easily misdiagnosed, and the drug resistance rate is high. Identification of mycobacterium species and detection of drug sensitivity play an important role in clinical diagnosis and treatment.

OBJECTIVE: To analyze the clinical characteristics of patients with bloodstream Acinetobacter baumannii infection in Intensive Care Unit (ICU).
 METHODS: Eighty-three ICU patients with bloodstream Acinetobacter baumannii infection from January 2012 to March 2015 were retrospectively analyzed, including infection-related risk factors, drug-resistant bacteria, treatments and prognosis.
 RESULTS: Among 83 patients, 60 patients (72.29%) were male, 23 (27.71%) were female. The youngest patient was 40 days old, the oldest was 92 years old, the age was (46.23±19.22) years old. In total, there were 20 patients (24.10%) with plural bacterial infection in blood, 60 (72.29%) with more than 3 kinds of disorders, 52 patients suffered homologous bacterial infection in blood and other organs. Among these cases, lower respiratory tract had the highest percentage of homologous bacteria (29 cases), followed by catheter (11 cases), wound secretion (8 cases), cerebrospinal fluid (3 cases) and ascites (1 case). The risk factors of bloodstream infection by Acinetobacter baumannii included catheterization, serious primary disease and basic disease, usage of corticosteroids, surgery and invasive operation and so on. Acinetobacter baumannii were highly resistant. Most of them were multi-drug resistance, and some were pan-drug resistance. It showed more than 80% drug resistant rate to antibiotics except sulbactam, cefopcrazone and amikacin. Among 83 patients, 55 cases (66.26%) were dead, 25 cases (30.12%) were improved and 3 cases (3.62%) were cured.
 CONCLUSION Acinetobacter baumannii are highly and multidrug-resistant to commonly used antibiotics. Patients in ICU suffering serious basic diseases should be shorten hospitalization time, restricted the use of breathing machine and immunosuppressant. It must carry out disinfection for invasive operation to reduce the risk of bloodstream infections, and the abuse of antibiotics must be avoided to slow bacteria resistance.
