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.

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.

Objective:To study the clinic effects of Prescription Zhuyun-Ⅲ(ZYⅢ) on early pregnancy women diagnosed as threatened abortion,and its mechanism in immunity and endocrine by determining the changes of serum Th1 and Th2-type cytokines,progesterone(P) and ?-human chorionic gonadotropin(?-HCG).Methods:The treatment group comprised of 30 early pregnancy women diagnosed as threateded abortion as well as deficiency syndrome of deficiency syndrome of Spleen or Kidney diagnosed by TCM,the control group consisted of 20 normal early pregnancy women at similar gestational age.The treatment group was administered with ZYⅢ for 4 weeks.Peripheral blood samples from the above two groups pre-and post-treatment were collected,serum Th1 type cytokine IL-2 and Th2 type cytokine IL-10 were determined by flow-cytometry.Serum P and ?-HCG were determined by ELISA.Results:①The serum IL-2 level and the ratio of IL-2/IL-10 in the treatment group before therapy were significantly higher than the control group(P

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.

Conclusion: This method is simple and accurate, and can be used for the quality conltrol of Xiaochaihu Tablets.

Objective To sum up the precaution and treatment of the postoperative complications of the aged patients with cerebral impairments. Methods The clinical data of 96 aged patients with cerebral impairments were reviewed, 76 patients of which had postoperative complications. Results Among the 76 patients with postoperative complications, 24 cases died, and the death rate is 31 7%. 11 patients died of lung failure due to lung infection, 4 patients died of massive bleeding of upper digestive tract, 3 patients died of heart failure, 4 patients died of renal failure and the other 2 patients died of recurrent hematoma. Conclusions The postoperative death rate of the aged patients with acute cerebral impairment is fairly high, and the main death cause is postoperative complications, so we should treat this kind of patients in time and prevent the occurrence of complications.

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.

A systematic review is based on randomized controlled trials (RCTs), and the reliability of its conclusion is closely related to the quality of original literature. The low quality of existing RCTs in China leads to the failure of conclusive findings in systematic reviews when evaluating the effectiveness of interventions. It is almost universal for systematic reviews to draw the conclusion that "further well-designed multicenter and large-scale RCTs are still required to confirm the beneficial effects of interventions". This paper analyzed the current status of RCTs in China, discussed the influence of including trials of low quality in a systematic review and assessed how a systematic review should be carried out under such circumstances. Furthermore, the methods to evaluate the quality of RCTs were introduced and evaluated. Finally, several strategies were proposed to improve the quality of RCTs in China: foster an honest academic and social environment, enhance the training of doctors on clinical research methodology, promote the implementation of clinical registration systems and strengthen the quality control of clinical research and the medical journals regulations on the quality of submitted papers.

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.
