1.Diagnosis and management of intraparotid facial nerve schwannoma.
West China Journal of Stomatology 2015;33(4):431-435
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 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.
4. Patent family strategy analysis of lipitor
Chinese Pharmaceutical Journal 2014;49(5):437-440
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 observe therapeutic efficacy and safety of glutamine combined with low molecular weight heparin in the treatment of elderly severe pneumonia (SP).METHODS:In retrospective study,88 SP elderly patients were divided into control group (44 cases) and observation group (44 cases).Based on conventional treatment,control group was given Enteral nutritional suspension via nasal feeding.Observation group was additionally given Alanyl glutamine injection 20 g,dissolved in Amino acid solution with ratio of 1:5 at least and maximum concentration belowing 3.5%,i.v.,once a day+Low molecular weight heparin calcium injection 4 KU/kg subcutaneously,once a day,on the basis of control group.Both groups were treated for 7 d.Clinical efficacies and postoperative recovery (ventilator support time,pulmonary rale disappearance time and ICU hospitalization time) were observed in 2 groups.The levels of IgA,IgG,TNF-a,hs-CRP,APACHE Ⅱ score,coagulation function indexes (APTT,D-D,FIB,PT,PLT),blood gas analysis indexes [pa (CO2),SpO2,Oi,pa (O2)] and receptor for advanced glycation end products (RAGE),the occurrence of ADR before and after treatment were also observed in 2 groups.RESULTS:Total response rate of observation group (90.91%) was significantly higher than that of control group (72.73%),while ventilator support time,pulmonary rale disappearance time and ICU hospitalization time were significantly shorter than control group;the incidence of ADR was significantly lower than control group,with statistical significance (P< 0.05).After treatment,the levels of IgA,IgG,Oi,SpO2 and pa (O2) in 2 groups were significantly higher than before treatment,and the observation group was significantly higher than the control group.The levels of TNF-αt,hs-CRP,APACHE Ⅱ score,coagulation function indexes,pa(CO2) and RAGE in 2 groups were significantly lower than before,and the observation group was significantly lower than the control group,with statistical significance (P<0.05).CONCLUSIONS:Based on conventional treatment,glutamine combined with low molecular weight heparin show significantly effect on elderly SP,effectively improve cellular immune function,coagulation function and blood gas analysis indexes and reduce RAGE level with good safety.
