OBJECTIVETo study the surgical management of enophthalmos after severe malar maxillary complex fracture.

METHODSThe X-ray and CT examination were performed before operation to diagnose the orbital fracture and intraorbital tissue displacement. The fractured orbital rim was repositioned intraoperatively, followed by implantation of shaped titanium mesh to rebuild the orbital floor. The Medpor was inserted above the titanium mesh to correct the enophthalmos.

RESULTSFrom Sept. 2007 to Jan. 2009, 6 cases of enophthalmos after severe malar-maxillary complex fracture were treated. The enophthalmos was corrected or improved obviously in all the patients.

CONCLUSIONSThe enophthalmos after severe malar-maxillary complex fracture can be corrected or obviously improved. Shaped titanium mesh can be used to rebuild the orbital floor with the Medpor to reconstruct the intraorbital tissue volume.

Objective To study the efficacy and toxicity of gensenoside-Rg3 (Rg3) combined with radiotherapy on non-small cell lung cancer ( NSCLC ) at advanced stages (Ⅲ and Ⅴ ).Methods Sixty-three patients with stage Ⅲ or Ⅳ NSCLC were divided randomly into two groups:treatment group ( n =35 ) treated with Rg3 combined with radiotherapy and control group ( n =28 ) treated with radiotherapy alone.The efficacy and side effects were compared after the treatment.Results The response rate ( CR + PR) of the treatment group was 57.14％,significantly higher than that of the control group (32.14％,x2 =3.91,P ＜ 0.05).The median survival time of the treatment group was 14.2 months,significantly longer than that of the control group ( 11.2 months,x2 =2.07,P ＜ 0.05 ).The one-year survival rate of the treatment group was 62.86％,significantly higher than that of the control group (39.29％,x2 =4.40,P ＜0.05).The incidence rates of side effects of the treatment group were all lower than those of the control group,but there were not significant difference. Conclusions Gensenoside-Rg3 combined with radiotherapy is effective for advanced stage NSCLC,with attenuation and synergistic effects.

OBJECTIVETo investigate the value of application of mandibular outer cortex as bone graft by comparing its bone absorption with cranial outer cortex.

METHODS8 minitype grown-up pigs at the age of 8 - 12 months underwent surgery of taking out the same size (2.5 cm x 1.0 cm) of outer cortex from mandible and craninium. The volume of the outer cortex was measured by volume-displacement method. Then the outer cortex of mandible and cranium were onlay grafted to the each side of the pig snout, respectively. 12 weeks later, 2 pigs were randomly selected for histological examination. The other 6 pigs were killed 24 weeks after surgery for measurement of the bone graft volume and histologic examination.

RESULTSThe bone graft absorption rate was (41 +/- 5)% for mandibular outer cortex and (46 +/- 12)% for cranial outer cortex, showing no significant difference between them (P = 0.51). The histologic examination results also had no marked difference in the bony healing and reforming between the two graft.

CONCLUSIONSMandibular outer cortex is a good donor site for onlay bone graft in craniofacial region.

OBJECTIVESTo test the serum sexual hormone and sperm cytology in aspermia patients.

METHODSRadioimmunoassay (RIA) and Wright-Giemsa stain were used to detect serum sexual hormone and sperm cytology in 45 aspermia patients.

RESULTSAmong the 45 patients, spermatogenetic cells were detected in 16 patients(35.6%). The level of serum testerone were decreased in 16 patients, and FSH, LH were increased in 13 cases as well as that of PRL in 4 cases.

CONCLUSIONSThese results suggested that the testis function was demaged, the ratio of T/LH could further reflect the function of Leydig cells, the detection of PRL were significant only in diagnosis of aspermia induced by hypermia. It is an important index in identifying obstructive and non-obstructive aspermia and has important significance in estimating the extention of testis demage and commanding the clinical treatment of serum hormone detection and sperm cell analysis.

OBJECTIVETo illustrate the morphological changes of mandible after angle-splitting ostectomy.

METHODSFrom January 2006 to April 2008, 10 cases had undergone mandibular angle-splitting ostectomy to reduce the width of the lower face. For each patient, CT datum of mandible at three stages (preoperative, immediate postoperative, 6 months postoperative) were collected. By the application software of reverse engineering (Surfacer V9) and true-up and dissection techniques based on three-dimensional spiral computed tomography (3D-CT), operative efficacy and bone regeneration at the operation area of angle-splitting ostectomy were evaluated 6 months postoperative.

RESULTS1) Concavity could be seen at the angle-splitting ostectomy area 6 months postoperative, especially at the mandibular external oblique line region. Average cup depth was (3.64 +/- 1.67) mm by contrasted to preoperative. Diminution of bone volume was 55% +/- 9% for the local operative area 6 months postoperative. 2) Bone regeneration could be seen at the area that mandibular outer cortex had been removed. Compared with immediate postoperative, ratio of neoformative bone was 84.6% +/- 7.3% 6 months postoperative. The main region of bone regeneration was mandibular angle.

CONCLUSIONMandibular angle-splitting ostectomy is an effective technique for reducing the width of the lower face. Masseter muscular movement should be restricted postoperative to prevent hyperostosis at the angle area.

Objective To explore the causes of dengue fever resurgence in Guangxi, and to analyze the risk factors of dengue fever. Methods The descriptive epidemiological analysis was conduced based on the dengue fever data reported from 2006 to 2015, and the surveillance results of aedes and antibody levels in health population from 2013 to 2015 in Guangxi. Results Before 2013, dengue fever was imported from foreign country in Guangxi, accounting for 95.35％(42/45), and 75.71％of the imported cases was imported from Southeast Asia. The local outbreak of dengue fever was happened in 2014, accounted for 94.02％(849/903) of the total number of 10 years. From onset to diagnosis, Guangxi dengue fever cases need 0-70 d (median time interval is 6 d). Cases were reported year-round, but the peak season for the onset of dengue fever was from September to November, accounting for 96.46％of all cases (871/903). The number of cases reported in Nanning was the most (83.37％), followed by Wuzhou city (7.44％) and Guilin city (4.81％), and all the three cities had dengue fever outbreaks. The cases were mainly commercial service staff (27.80％) and houseworkers and unemployed people (18.16％). Results of aedes monitoring showed that the density of aedes was high in Guangxi. In more than 50％ of the monitoring seasons the breteau index (BI) stayed greater than 20. However, the antibody positive rate was only 3％ in the healthy residents of Guangxi. Conclusion The risk of dengue fever is high in Guangxi. Therefore, it is essential to emphasizing idea of prevention and control, strengthening immigration surveillance, improving diagnosis ability, enhancing public health education, and expanding monitoring range.
