Pleomorphic adenoma (PA) is a rare benign tumor in the pharynx. We presented a case with a huge PA in the pharynx. MRI displayed oropharyngeal mass, considering benign tumor. Preoperative fine-needle aspiration and cytology biopsy were important to confirm the diagnosis of PA preliminary. Extracapsular complete dissection for PA was performed under general anesthesia with tracheotomy subsequently. Postoperative histopathological examination confirmed the diagnosis of PA. The patient was discharged a week after operation and no recurrence was found in the following 8 months.

Hypoxia-inducible factor-1 (HIF-1) is an inportant regulatory factor in adapting to hypoxia in the hypoxic environment for cells.The changes of the numbers of HIF-1 in cells may regulate hypoxia-responsive gene transcription.HIF-1 may inhibit neuronal apoptosis and thus play a ncuroptotective role,and may also show a neurotoxic effect by inducing neuronal apoptosis.

Objective To investigate the influence of traditional Chinese medicine on nutritional status and function of immune in post-esophagectomy patients with esophageal carcinoma.Methods 70post-esophagectomy patients in our hospital were randomly divided into 2 groups:a control group (35 cases)and a observation group (35 cases).The control group were treated with postoperative nutrition programs of our hospital,while the observation group were treated postoperative nutrition programs combined with Chinese traditional medicine group in order to observe and analyze the nutritional status and the function of immune at preoperative and 7 days treatments.Results The TP/ALB/IgG/CD3+were (54.5±18.3)g/L and (50.5±11.8)g/L,(36.3±11.7) g/Land (32.8±12.2)g/L,(8.7±3.1)g/L and (7.5±2.8)g/L,(75.4±12.8)％ and (70.1±12.9) ％ in the observation group and the control group respectively,showing significant difference (P＜0.05).The CD4+/CD8+ were (2.5±0.8)and (2.1 ±0.6)in the observation group and the control group respectively,showing significant difference(P＜0.05).Conclusion The nutritional status and function of immune in post-esophagectomy patients with esophageal carcinoma were declined.Rational application of traditional Chinese medicine assisted the nutritional status and function of immune in post-esophagectomy patients with esophageal carcinoma.

Titanium & titanium alloy are popular in dentistry as dental material because of their good mechanical properties and extremely good biocompatibility. The bonding strength between the titanium and the resin agent is the decisive factor in evaluating the success of resin-bonded restoration. Appropriate surface treatment on the titanium is an effective way to reinforce the bending strength. The purpose of this review is to summarise the relevant studies and introduce some latest findings.

Objective To observe curative effect of acupuncture treating children acute upper respiratory infections (AURI).Methods According to random digits table,150 children from clinic emergency department were averagely bring into a acupuncture treatment group and a western medicine treatment group.Patients in the acupuncture treatment group received the treatments of acupunctureing one side of “SiGuan”points,bloodletting in apex satyri,and reducing temperature with tepid sponge bath; while patients in the western medicine treatment group received the treatments of taking ibuprofen suspension,using external pyretolysis patches on forehead,and reducing temperature with an alcohol sponge bath.After the treatment,the near future therapeutic effects:the time of pyretolysis,fevering again in 24 hours and convulsion time,and the prostecdtive efficacy:the time of cough continuing,AURI happening again in 3 months and recovery time of appetite were both observed.Results The time of pyretolysis,fevering again in 24 hours,convulsion time,the time of cough continuing,recovery time of appetite and AURI happening again in 3 months of acupuncture treatment group was(15.6±5.8) minutes,(12.7±3.3) hours,(0.6±0.1) times,(2.3±1.8) days,(2.4±1.6)days,and (35.2±3.9) days respectively; and the western medicine treatment group was (25.5±7.3) minutes,(8.6±4.1) hours,(2.1±0.5) times (6.2±2.4) days,(3.8±1.5) days,and (18.4±5.2) days respectively.Comparing between the two groups,P＜0.05.Conclusion Acupuncture can significantly decrease the time of pyretolysis,cough continuing,recovery time of appetite and convulsion time,and significantly increase the time of fevering again in 24 hours and AURI happening again in 3 months in patients with AURI.

Objective To study the best process of puerarin refined.Methods Results of the research on the selection of dissolved agent, agent and precipitator, and column chromatography of the resin, alumina, silica gel, fly ash and activated carbon were used to study the combined process. Results The average purity of optimization of the three craft products were 99.06052%, 99.22620% and 99.69880%.The yield of average values were 44.180%, 44.438% and 42.642%.Conclusion This study optimized the optimum process is feasible, puerarin purity is more than 99%, the yield is above 40%.

Objective To analyze the results of blood lipids examination in medical workers,so as to understand the cause of ab-normal blood lipid level and formulate the strategy of health education.Methods 500 cases of hospital workers were enrolled as subjects for the study.Under fasting conditions,the samples of the upper arm vein blood were collected,and the detection of total cholesterol(TC),triglycerides(TG),low-density lipoprotein(LDL),and high density lipoprotein(HDL)of serum were proceed on automated analyzers.The results were analyzed.Results In all the 500 workers,there were 152 cases with hyperlipoidemia,ac-counting for 30.4%.The dyslipidemia rate of male workers was 34.7%,and which of female workers was 24.4%.≤30 age group had the lowest dyslipidemia rate(12.9%),and >45-50 age group had the highest dyslipidemia rate(45.8%).There was signifi-cant difference between them(P <0.01).Conclusion The dyslipidemia rates of workers are different across age and gender.It is helpful for workers to have focused health education to improve their live qualities.

Quantum dots( QDs) as a new type of nanostructured luminescent materials have been widely used in biology, materials science, and physical optics. QD-based biosensors can rapidly and accurately detect biological macromolecules or inorganic molecules both in vivo and in vitro. The surface of QDs, prior to their biological detection applications, needed to be modified to enhance their fluorescence properties and lower their biological toxicity. Currently, the surface modification technologies mainly include polymer modification, thiol compounds modification, mercapto propionic acid compounds modification and organic groups modification. Various biosensors can be developed by adopting different modification techniques, which have been adopted to locate and track a variety of biological molecules in vivo. Although a large number of literatures have reported the biological applications of QD-based biosensors, rare systematic reviews of surface modification technologies on QDs have been witnessed. In this paper, we reviewed the surface modification technologies of QDs in biosensors and their medical applications.

A total of 450 residents from three neighborhood committees of Ba'nan were selected to assess their willingness to accept paid influenza vaccine and the influencing factors.Among them,273(60.7％) were willing to accept paid influenza vaccine.Age,economic status,health,flu recognition and vaccine approval were the major influencing factors of vaccination.

22 cases of posttraumatic neuroma (TN) were seen in Kunming General Hospital from 1979 to 1985.Clinical and pathologycal study showed that:(1) One of the main causative factors of TN was wound infection.(2)It took at least 6 months to form a TN.Those TN which formed within 6 months belonged to chronic proliferative inflammation.(3)Four Clinical and pathological findings were necessary to diagnosis TN.(4) The term,tumor-like nerve hyperplasia.not only a more accurate term than TN.but also helps avoid misunderstanding.
