Objective To analyze the epidemiological characteristics of overseas imported malaria reported in Chongqing City from 2011 to 2015,so as to provide the evidence for improving the imported malaria control strategies. Methods The epi-demiological data of overseas imported malaria cases were collected and analyzed descriptively for the species,original coun-tries,diagnosis and treatment in Chongqing City from 2011 to 2015. Results A total of 148 overseas imported malaria cases were reported in Chongqing City from 2011 to 2015,in which 96(65.54%)cases were falciparum malaria,and 37(24.32%) cases were vivax malaria;125(84.46%)cases were infected in Africa,and the rest of 23(15.54%)cases were infected in Southeast Asia. Most of the patients were 30 to 50 years old male workmen,and the ratio of male to female was 11.42:1. There was no obvious seasonal distribution among the reported timelines of the cases;however,there were two small peaks from June to August and from January to February. The median interval time of imported malaria cases from malaria onset to see a doctor was 1 day and from seeing the doctor to get malaria diagnosis was 2 days. The patients'first selected institutions were county medical institutions(50 cases,33.78%),then provincial medical institutions(36 cases,24.325%)and private doctors(20 cases,13.51%),and only 79(53.38%)patients got malaria diagnoses in their first selected institutions. The standard treatment were provided to 142(95.54%)cases. There were 43(29.05%)patients had serious complications and three patients were dead. Conclusion It is very important to enhance the multi-sector's collaboration to establish the collaborative investigation mechanism for screening malaria patients,and strengthen malaria health education for overseas workers and training courses in primary care medical institutions.

The readjustment of the army establishments has resulted in the mergence of some sanatoriums into hospitals,which has given rise to a novel mode of management and offered a new opportunity for the development of sanatoriums.In the past four years since the mergence of our sanatorium into Nanjing General Hospital in 2004,we explored the mode of integrating recuperation with treatment and combined the resource advantages of ours with the technical superiority of the hospital,which led to an improvement of our competitive ability and comprehensive service and accordingly promoted the overall development of the sanatorium.

OBJECTIVETo investigate the clinical results of external fixation and AO titanium elastic intramedullary nailing for treatment of tibia-fibula comminuted closed fractures.

METHODSFrom June 2010 to June 2012,58 patients with tibia-fibula comminuted closed fractures were treated with external fixation and AO titanium elastic intramedullary nailing, including 31 males and 27 females with an average age of 38.5 years old ranging from 21 to 57 years old. According to the system of AO Classification, the fractures were classified as type B1 in 9 cases,type B2 in 7 cases, type B3 in 10 cases, type Cl in 14 cases, type C2 in 12 cases,and type C3 in 6 cases. According to the system of Winquist-Hanson,the fractures' comminuted were classified as grade 1 in 23 cases, grade 2 in 17 cases, grade 3 in 12 cases, and grade 4 in 6 cases. According to the system of Johner-Wruhs, clinical results were compared between different type and grade groups by the time of last followed-up.

RESULTSAll 58 patients were followed up with an average time of 6.8 months (ranged from 18 to 36 weeks). All fractures had clinical healing with an average time of 28 weeks (ranged from 24 to 32 weeks). The total rate of good to excellent results was 91.4%. The rate of good to excellent in the group of grade 1 was higher than that of other grades. The complication rates and fracture healing time would increase respectively with higher Winquist-Hanson's grade. The complication rates in the group of type C3 was higher than that of other types, but the rate of good to excellent was lower than that of other types. The complication rates in the group of type B1 was lower than that of other types,but the rate of good to excellent was higher than that of other types.

CONCLUSIONMinimal invasiveusing AO titanium elastic intramedullary nailing combined with external fixation for treatment of tibia-fibula fractures especially for the multiple-segment,long spiral mild-to-moderate comminuted with hidden fracture can get satisfactory reduction and reliable fixation,it conformes to the principle of BO completely, protects the fracture end blood supply,reduces the external fixation time, has less skin soft tissue complications, postoperative function recovered satisfactorily.

OBJECTIVETo evaluate the role of the combined periodontic-orthodontic treatment in the esthetic reconstruc- tion of the anterior teeth area following periodontitis.

METHODSThirteen adult patients with anterior teeth displacements were treated. The probing pocket depth (PD; 102 teeth, 612 sites), bleeding on probing (102 teeth, 204 sites), papilla index (PI; 128 papillae), and papillary height (PH; 128 papillae) of each patient were assessed at baseline, 3 months after the initial therapy, and the end of the orthodontic treatment. Non-parametric and paired-sample t tests were carried out for the statistical analysis of the data.

RESULTSThree months after initial therapy, the sites with PD ≤ 3 mm accounted for 79.58% (487/612) of the observed teeth, and 88.73% (181/204) of the buccal and lingual sites of the teeth showed negative bleeding on probing. These findings were better than those at baseline [26.31% (161/612) and 22.06% (45/204), respectively] (P < 0.05), but no sig- nificant difference was observed compared with pro-orthodontic treatment (P > 0.05). Prior to orthodontic treatment, the levels of the PI of 8 and 21 papillae were III and II, respectively, among the 128 observed papillae. After the orthodontic treatment, 51 papillae were at level III and 68 papillae were at level II. The PH of the 102 papillae was 2.84 mm ± 0.62 mm after ortho- dontic treatment. This result indicated significant difference compared with that of pre-orthodontic treatment (1.69 mm ± 0.57 mm) (P < 0.05).

CONCLUSIONAfter initial therapy, moderate orthodontic teeth movements may reconstruct the interproximal soft tissue, with esthetic improvement of the papillary level and resolution of the periodontal defects.

OBJECTIVE:To investigate the improving effect of phenylethanoid glycosides (PhGCs) from Tibetan medicine Phlomis younghusbandii on rats with acute high-altitude cerebral edema. METHODS:60 Wistar rats were randomly divided into a normoxia control group (isometric sterile water for injection),a hypoxia model group (isometric sterile water for injection),a dexamethasone group(4 mg/kg),and three groups of PhGCs at high(400 mg/kg),middle(200 mg/kg)and low(50 mg/kg)dos-es,with 10 rats in each group. The rats were given drugs,ig,6 d before the establishment of models. On the 4th day of administra-tion,ig,the rats in all groups except the normoxia blank group were placed in a simulated 8 000 m altitude plateau environment for 72 h hypoxic exposure to establish the rat models of high-altitude cerebral edema. Following HE stain,the pathological changes in rats’brain tissues were observed under the light microscope. Dry-wet proportion method was used to determine the water con-tents in rats’brain. The content of MDA and the activities of SOD and GSH in rats’brain tissues were detected. Enzyme-linked im-munosorbent assay was adopted to determine the contents of IL-1β and TNF-α in rats’serum and brain tissues. RESULTS:Com-pared to the rats in the normoxia control group,those in the hypoxia model group showed obvious brain edema,and thickened lacu-nas around cells and vessels and inflammatory cell infiltration, higher water contents and MDA and weaker activities of SOD and GSH in brain,and higher contents of IL-1β and TNF-α in serum and brain tissues. There were statistically significances (P<0.01 or P<0.05). Compared to the rats in the hypoxia model group,those in the groups of PhGCs at high,middleand low dosages demonstrated less inflammatory cell infiltration and lower water contents in brain tissues,in which the groups of PhGCs at high and middle dosages demonstrated lower content of MDA and stronger activities of SOD and GSH in brain tissues, and lower contents of IL-1β and TNF-α in serum and brain tissues. There were statistically significances (P<0.01 or P<0.05). CONCLUSIONS:PhGCs can obviously alleviate the acute cerebral injury in rats which is caused by acute hypoxia and has im-provement effect to some degree on the rats with acute high-altitude cerebral edema.
