Intraparotid facial nerve schwannoma (IFNS) is a rare benign tumor. The management of IFNS is very challenging because of the lack of appropriate methods for preoperative diagnosis, which is often conducted intraoperatively in most cases. This article reviewed the literature on IFNS recorded in PubMed from 1958 to 2014 and described in detail its clinical manifestations, diagnoses and differential diagnoses, and treatment options. Accurate diagnosis for IFNS mainly depends on intraoperative observation and postoperative histological examination. Preoperative facial nerve function, localization, and adherence, as well as preferences of IFNS patients are important factors to consider in the decision-making process for IFNS management to optimize the outcomes. Surgical resection is usually reserved for patients with facial function of House-Brackmann grade III or worse; otherwise, conservative treatment can be adopted.

Objective To study the effects of repetitive transcranial magnetic stimulation (rTMS) on rats'locomotor function after hemisectional spinal cord injury (SCI). Methods A model of hemisectional SCI was established at the T10 segment in 12 rats,which were then randomly divided into an SCI-rTMS group and an SCI-control group.Another 6 rats served as normal controls.The SCI-rTMS group received threshold rTMS daily for 4 weeks,while the SCI-control group was given sham rTMS.The normal control group was left without any treatment.BassoBeatti-Bresnahan (BBB) locomotor scores were recorded weekly.Motor evoked potential (MEP) was detected at the 28th day after the operation.Neurofilament-200 (NF-200) was detected with immunofluorescent staining of the spinal cord lesions. Results The BBB scores in the SCI-rTMS group improved more than those in the SCI-control group.MEP of the fight hindlimb was detected in the rTMS group,but not in the control group.Expression of NF-200 marker increased significantly more than in the rTMS group. Conclusions rTMS can improve locomotor function of rats after spinal cord hemisectioning,which may result from increased expression of NF-200 and the regeneration of axons.

Objective To investigate the effect of risperidone on S100B protein and its intervention on the relapse of heroin addicts. Methods From January 2014 to March 2014, 70 cases heroin addicts in the second detection center in Xining were selected as objects, three patients dropped out, and the left were randomly divided into control group(n=33) and experimental group(n=34) , which were given detoxification for 10 days, rehabilitation for 5 days, while the experimental group were given risperidone intervention.The condition of craving degree for heroin, relapse and incidence of adverse reactions between two groups were compared.Serum S100B protein levels were detected by ELISA.The efficacy of risperidone was analyzed.Results The craving degree for heroin between two groups was of no significant differences, after drug treatment, the craving degree for heroin of experimental group were significantly lower than those of control group at the time-point of hospital discharge, 1 months after discharging and 3 months after discharging(P=0.013, P =0.008, P =0.005).The differences of relapse condition between two groups in 3 months after discharging were statistically significant (P=0.003), the relapse incidence of experimental group(11.8%) was significant lower than that of control group(54.5%). Besides, the differences of relapse condition among different craving degree groups were statistically significant in two groups respectively(P=0.005, P=0.008).Serum S100B protein levels of experimental group , in different periods were lower than those of control group, with statistical significance ( P<0.05); There were 5 cases of insomnia, 3 cases of headache, 3 cases of thirsty, 2 cases of mild extrapyramidal symptoms in test group, but all above were mild and relieved on their own after withdrawal, no similar symptoms were observed in control group.Conclusion Risperidone intervention is a safe and effective method to prevent heroin addicts from relapsing, it maybe with the mechanism of reducing the levels of serum S100B protein, but it needs further research and efforts to put it in clinical applications of herion addiction treatment.

The purpose of this study was to observe the neuromechanism and clinical effects of percu-taneous radiofrequency thermocoagulation cervical rarmi dorsales for the patients with headache of cervical origin. 16 patients were selected for the present study.Excellent result was obtained in thirteen cases.It is suggested that there was a close relationship between the injury of the cervical rami dorsales and headache of cervical origin,Radiofrequency thermocoagulation cervical rami dorsales plays a positive role in the treat-ment of headache of cervical origin.

The aim of the research is to introduce the kinds of medical Internet resources and worth of the Internet for the development of clinical, education and research of rehabilitation medicine. There are rich medical information in the internet and it is important for the rehabilitation medicine develol)ment. The strategies of exploring the rehabilitation medical internet resources are put forward.

Objective The purpose of this study was to investigate the effect of blood supply decrease on glycosaminoglycans(GAG)of the cartilage in the temporomandibular joint(TMJ) . Method Four rabbits were used as controls, and 16 rabbits were injected 5% sodirm morrhumate through carotid artery unilaterlally. All specimens were examimined histochemically. Result A reduction in alcian(AB) blue staining was observed after operation, a gradual increase in AB staining with blood supply restoration of TMJ tissue was observed. Conclusion The result suggests that the decrease in blood supply of the temporomnandibular jorint leads to the loss of GAG in the condylar cartilage, which may play an important role in pathogenesis of osteoarthrosis.

X-ray cephalometry was used to analyze craniofacial morphology in 32 males and 23 females with operated cleft palate. They underwent primary palatoplasty at the ages of 4 to 7 years and examination at the age of 18 to 25 years old. The cephalometric data were compared with that of the native Hubei adults with normal occlusions. The results indicated the cranial base in the cleft group was morphologically similar to that of the normal controls, there were a decreased angle of skeletal facial convexity, a shorter maxilla, an increased gonial angle and a more open mandibular plane angle in the clefts. All of these differences were significant. Surgical treatments at the age of 4 to 7 years old could cause craniofacial deformities at adults.

OBJECTIVE: To study the features and the functions of patent family inpatentregime, thus to provide experience for the Chinese domestic pharmaceutical enterprises in the development and the management of patent. METHODS: In the case of lipitor patent family, technical topics, application period and the inner relationship were analyzed, aiming to acquire the constructing strategy of patent family in pharmaceutical field. RESULTS AND CONCLUSION: Crystal and composition patents are also important in the surrounding patent layouts besides the chemical compound patent. After the application of the chemical compound patent, multi-level patent families can be constructed by making use of the priority and divisional application system, that can reinforce patent strategy of enterprise.

Objective To compare the dose distribution of reserved planned tangential beam IMRT(2-field IMRT) with multifields beams IMRT(6-field IMRT) of the bulk-recurrent chest wall in postmastectomy breast cancer patients.Methods For 8 patients with chest wall in postmastectomy breast cancer bulk-recurrence,2-field IMRT and 6-field IMRT plans were generated on PTV in Pinnacle Planning System.The prescribed dose of PTV was 50 Gy in 25 fractions and GTV was 66-70 Gy which irradiated incrementally by subsequent plan in 8-10 fractions.The conformal index (CI) and homogeneity index (HI) of 95％ of prescribed dose over PTV were compared,while the dose distribution on ipsilateral lung and heart were evaluated.Results The CI of PTV by 6-field IMRT (0.66 ± 0.08) was higher than that of the2-field IMRT (0.53±0.10)(t=7.99,P＜0.05).The HI ofPTV by6-field IMRT (1.36±0.08)waslower than that of 2-field IMRT (2.19 ±0.78) (t =9.04,P ＜0.05).There was no statistical difference in V5,V10,V20 and V35 for ipsilateral lung and in D V35 and D for heart between two plans.Conclusions Compared with 2-field IMRT,6-field IMRT might have a better dose distribution on planning target volume(PTV) for chest wall in postmastectomy breast cancer bulk-recurrence patients,butthere is no significant difference in dose-volume of ipsilateral lung and heart between two plans.
