Objective To observe the effects of Kinesio taping on upper limb spasticity after stroke. Methods From March to Novem-ber, 2015, 39 stroke patients were divided into Kinesio taping group (Kinesio taping and rehabilitation, n=13), white taping group (white tap-ing and rehabilitation, n=13) and blank group (rehabilitation, n=13) randomly. They were evaluated with modified Ashworth Scale (MAS), Fugl-Meyer Assessment (FMA) of upper limbs and the modified Barthel Index (MBI) before treatment, four and eight weeks after treat-ment. Results There was no significant difference among the three groups in the scores of FMA and MBI (P>0.05) four weeks after treat-ment, but the score of MAS improved more in the Kinesio taping group than in the other two groups (P<0.05). The scores of MAS, FMA and MBI all improved more in the Kinesio taping group than in the other two groups (P<0.05) eight weeks after treatment. Conclusion The application of Kinesio taping can relieve upper limb spasticity, and improve motor function and activities of daily living for patients with stroke.

With a long duration of the CHB, patients who have economic pressures and physical problems will get changes in their psychological status, which are involved in the development of the disease. Moreover, poor thera-py compliance and insight of their disease, negative mood of anxiety and depression also have effects the prognosis of disease. Therefore, mental factors play a vital important role in the development and prognosis of CHB patients, health education and mental intervention are the most effective way to avoid the psychological disorder of patients.

Trichomonas vaginalis parasitizes in human genitourinary tract.The protozoon adhering to target cell plays a critical role in its contact-dependent cytotoxicity.The enzymes synthesized by T.vaginalis can hurt vaginalis epithelial cells(VECs)directly.The focal immune reaction in the location parasitized by the parasite may provide an immunologic protection.Meanwhile,inflammatory factors and immune cells may aggravate the situation.In general,the T.vaginalis-induced contact-dependent cytotoxicity is a result of the involvement of some molecular and chemical factors.

Objective To study the X-ray characteristic of non-bacterial infectious pneumonia in children.Methods In 218 cases of non-bacteria infectious pneumonia, the pathogenic agents included influenza virus,parainfluenza virus,respiratory syncytial virus(RSV),adenovirus,mycoplasma(MYCO) and chlamydia.Of them,mono-pathogenic infection were 152,mixed infection were 66.All the cases had chest conventional radiograph,129 cases were followed up for 2 times or more.The average period of the follow up were 7 days.The findings of chest conventional radiograph were analysed.Results The radiographic features included lung marking heavy 197,disorder 187,straight 105 and obscure 194;pulmonary hilum enlarged 91,hilum obscure 93,emphysema 82,point opacities 81,pulmonary radio-translucent diminution 34,patch opacities 33.In 129 cases followed up the lesions were perfectly absorbed 9(6.97%),partly absorbed 56(43.41%),non-absorbed 53(41.08%),progress 7(5.42%).Conclusion The absorbed period of non-bacteria infectious pneumonia is more 7 days.There are some radiographic characteristcs in RSV and MYCO pneumonia.

Objective To explore the relationship of serum level of Cystatin C and suPAR with tumor infiltration, metastasis, and treatment of patients with malignant tumor. Methods: The serum levels of Cystatin C was detected by particle enhanced nephelometic immunoassay (PENIA) by 7600-010 full-automatic biochemical analyzer made in Japan. The level of suPAR was detected by ELISA. The serum levels of Cystatin C and suPARof 82 normal adults and 172 patients with malignant tumor were measured and compared. Results: The serum level of Cystatin C and suPAR in patients with malignant tumor was significantly increased compared with that of normal adults (P＜0.01 and P＜0.01). The level of Cystatin C and suPAR in terminally ill patients or patients with metastasis was significantly higher than that in the control group. The levels of the two indices in postoperative patients were lower than those in preoperative patients. No significant difference was found in the levels of the two indicies before chemotherapy or radiotherapy and after therapy. Conclusion: The serum levels of Cystatin C and suPARin patients with malignant tumor are correlated with tumor invasion, metastasis and surgical intervention. Detection of Cystatin C and suPAR levels in patients with malignant tumor is valuable for disease monitoring and treatment evaluation.

Oxytocin ( OT ) is a cyclic neuropeptide containing nine amino acids residues, in addition to the traditional roles of uterine contraction and lactation, it also plays important roles in the central nervous system and other peripheral organs, such as improving schizophrenia, autism - related psychiatric and psy-chological symptoms. Oxytocin exhibits its physiological func-tions by binding to its receptor (oxytocin receptor,OTR). Cur-
rently researchers are manipulating OT system by developing new OTR ligand ( agonists and antagonists ) , hoping to prevent and treat OTR related diseases. This paper reviews the latest devel-opment of OTR agonists, antagonists and its physiological roles in central nerve system and peripheral organs.

Objective To analyze the clinical characteristics of children with cyclic vomiting syndrome (CVS), summarize the clinical experience, and improve the awareness,diagnosis and treatment level of CVS.Methods The clinical data and results of long-term follow-up of the children with CVS were collected and analyzed from 1995 to 2009 in our department.Results Forty-six children were enrolled in the study, including 22 boys and 24 girls.Mean onset age was 4.5 years(ranged from 1 to 11 years)and the mean age at final diagnosis was 8.5 years (ranged from 4.5 to 14.5 years).Sixty-six and seventy-four percent of patients had family history of migraine and motional sickness respectively,whereas 83% patients had triggers.The clinical manifestation of CVS was severe episodic vomiting.The episodes had a rapid onset and sudden ending,persisted for several hours to days,and were separated by symptom-free intervals.The incidental symptoms were pallor, lethargy,intractable nausea,abdominal pain,headache,photophobia and dizzy.Twenty-nine patients diagnosed were followed up for 5 years at average.Five patients were treated with valproate,4 with cyproheptadine, 5 with cyproheptadine and valproate,5 with amitriptyline,cyprohep tadine and valproate,and 3 with cyproheptadine and flunarizine.All treated patients recovered mean 10 months(1.5 months to 2 years) years later and displayed the reduced number of episodes or the severity of episodes except 3 patients.Twenty-eight percent (8/29) of patients progressed to migraine headaches.Conclusion CVS is a relatively common disease in children and awareness of the condition should be increased.CVS should be considered when patients had recurrent vomitting and were completely healthy between the two episodes after excluding other pathological conditions.

Clostridium difficile is a gram-positive,anaerobic spore-forming bacillus commonly found in the environment and human gut.Excessive use of antibiotics,immunosuppressive agents and chemotherapy drugs may lead to overgrowth of the toxic strain of Clostridium difficile with high resistance,which are supposed to be the major contributing factors leading to Clostridium difficile associated diarrhea(CDAD).The globally increasing incidence of CDAD,especially the outbreak of nosocomial infection caused by the hypervirulent strain in North America,arouse worldwide attention.For providing new ideas to the early diagnosis and treatment of CDAD,this review summarize the latest development on pathogenesis and rapid laboratory diagnosis of Clostridium difficile.

Objective To invesgate the influence of aceclofenac to cartilage cell proliferation and substrate metabolism in osteoarthritis.Methods Select 65 cases of patients with osteoarthritis who were treated in Department of Rheumatism and Hematology of Affiliated Hospital of Qinghai University from September 2011 to September 2013.Patients were divided into observation group(n=35)and control group(n=30).The observation group were treated with aceclofenac,while control group were treated with ibuprofen,Compare the efficacy of patients in two group.Compare human articular cartilage cells of 5-bromodeoxyuridine(BrdU)positive rate,the content of glycogen protein(PG)and collagen type Ⅱ in two groups. Results The effective rate of observation group and control group was 74.29%and 73.33% respectively.There was significant difference between the two groups. Compared with control group,the joints pain,joints tenderness,15 meters walking time,daily activity ability(P<0.05).The incidence of adverse reactions of observation group(1 1.43%)was significantly lower than that of control group(P<0.05 ).The difference of BrdU positive rate in two groups had no statistical significance. Ⅱ type collagen content of observation group was significantly higher than that of control group (P <0.05 ).PG of observation group was significantly lower than that of control group(P<0.05).Conclusion The efficacy of aceclofenac is good and the incidence of adverse reactions is low in treatment of osteoarthritis.Aceclofenac can alleviate clinical symptoms of patients by increasing collagen type Ⅱ and decreasing PG.
