Epidemiological and clinical studies have provided compelling evidence that suggests a link between the relative lack of infectious diseases and the increase in allergic disorders. Asthma usually starts early in life. The early occurrence of asthma suggests that prinatal influences are of importance.Prenatal or postnatal exposure to endotoxins and other bacterial products may protect against the development of asthma in the infant. We will briefly outline the current state of the relationship of the perinatal infection and asthma in the infant, and focus our review mainly on possible rneehanism of perinatal infection providing protection against asthma in the infant, such as Th1/Th2 immune system, transcription factors, protection by maternal antibodies, endotoxin tolerance, pulmonary inflammation and genetic influences.

Objective To preliminary study clinical efficacy and toxicity of endostatin (ES) combined radiotherapy and chemotherapy in advanced non-small cell lung cancer (NSCLC),and evaluate its effectiveness and safety.Methods We retrospectively reviewed 64 patients with Ⅲ B-Ⅳ stage NSCLC of Harbin Medical University Cancer Hospital from February 2009 to February 2012.The patients were divided into two groups:chemoradiotherapy group,39 patients and ES add chemoradiotherapy group,25 patients.The short-term effect,the total efficiency,median survival time,progression-free survival time and disease-free survival time were compared.Results The total effective rate of chemoradiotherapy group was 76.9％,while the total effective rate of ES add chemotherapy group was 84.0％ (x2 =0.47,P =0.492).Chemoradiotherapy group,compared to ES add chemotherapy group,the median survival time,median progression-free survival time,median disease-free survival time were 11.52 months vs 16.51 months (x2 =3.74,P =0.042),7.32 months vs 10.37 months (x2 =5.32,P =0.025) and 5.21 months vs 7.57 months (x2 =4.56,P =0.035) respectively.The mainly adverse drug reactions were hematologic toxicity and gastrointestinal reactions,but there were no significant differences between the two groups; radiotherapy side effects mainly showed the grade 1 to 2 radiationinduced lung injury and radiation esophagitis (chemotherapy group had one case of grade 3 radiation-induced lung injury),but also had no significant differences between the two groups.Conclusion ES combined chemoradiotherapy can achieve a better short-term clinical efficacy without increasing adverse effects of radiotherapy or chemotherapy in advanced non-small cell lung cancer.

Objective To investigate the value of nerve conduction velocity detection in early diagnosis of peripheral neuropathy in type 2 diabetes.Methods Motor nerve conduction velocity (MCV)and sensory nerve con-duction velocity (SCV)for 94 patients were detected who was the first time diagnosed type 2 diabetes in our hospital from May 2014 to May 2015.The statistic results of nerve conduction velocity were conducted and then compared with clinical diagnosis to analyze the diagnosis rate for diabetic peripheral neuropathy (DPN).Results The abnormal rate of lower limb nerve conduction velocity was higher in the examined patients,which in the SCV of superficial peroneal nerve was especially highest(69.1%).The diagnostic rate of nerve conduction velocity in DPN was 71.3%,and the clinical diagnosis rate was 33.0%.The difference was statistically significant between the two diagnostic methods (χ2 =8.195,P =0.004).Conclusion Nerve conduction velocity detection has important value for the early diagno-sis of DPN.Patients for the first time diagnosed with type 2 diabetes should be carried out this detection to improve the diagnosis rate of DPN.

Objective To investigate the relationship between C-reactive protein (CRP) and postoperative cognitive function of female patients underwent cardiopulmonary bypass (CPB) cardiac surgery.Methods Sixty female patients were scheduled for CPB surgery from January 2012 to May 2013,aged form 35 to 60 years,mean aged (47.5 ± 12.5) years,and in state of ASAⅡ ～ Ⅲ.All patients had general anesthesia and CPB cardiac surgery.Blood samples were taken from peripheral vein before induction and 6 days after surgery.The neuropsychology assessment was measured with Wechsler Adult Intelligence Scale RC 2 + 1 (WAIS-RC) and digital span the first day preoperative,the 7th day,and the first month postoperative.The postoperative cognitive dysfunction (POCD) was judged with Newman style.Results (1) The rate of POCD of the 7th day and first month postoperatively was 50％ and 25％,respectively.(2) The Pearsong correlation showed negative correlation between CRP preoperative at the 6th day and the 7th day,and the first month postoperative WAIS-RC score(P ＜ 0.05).(3) The Pearson's figure showed negative correlation between CRP at the 6th day postoperative with digital span (P ＜ 0.05).Conclusions The ratio of POCD after CPB surgery was higher.It is instructively significant to monitor the variations of concentration of serum CRP for the selection of cognitive impairment in patients with cardiac-pulmonary bypass surgery.

The antimicrobial abuse has become an indisputable fact as well as a global public health concern.At the 2016 G20 summit in Hangzhou,the issue of antimicrobial resistance was also put on the agenda of world leaders.This paper analyzed the status quo of global antimicrobial resistance.With reference to the report Tackling drug-resistant infections globally: final report and recommendation written by British Lord Jim O′Nell published in May 2016,the main influencing factors of antimicrobial resistance were described.In addition,this paper proposed countermeasures for antimicrobial resistance,including carrying out large-scale promotional activities,improving global public health conditions,reducing antimicrobial use in agriculture,strengthening the global surveillance of antimicrobial resistance,developing new treatment products for infectious diseases,and building a new pattern of global response.

BACKGROUND: For the purpose of keeping the merits of traditional actual cautery, we improved traditional actual cautery and developed a pistollike electrocautery which has the function of heating and spraying oilpreparation (it has been issued national patent, patent number: 17634; patent number of medical electrocautery: 872106187). OBJECTIVE: To observe the effect of unique electrocautery of traditional Chinese medicine (TCM) on treating chronic tonsillitis as compared with cautery.DESIGN: Random sampling and case-controlled study.SETTING: Department of Otolaryngology, Affiliated Hospital of Liaoning College of Traditional Chinese Medicine; Surgical Department of Liaoning Oncology Hospital.PARTICIPANTS: Totally 80 patients with hypertrophy of tonsil were selected from the Department of Otolaryngology of the Affiliated Hospital of Liaoning College of Traditional Chinese Medicine in 1989. Inclusion criteria: degrees Ⅱ and Ⅲ of tonsil hypertrophy, without other serious cardiovascular and cerebral diseases, and consent. Exclusion criteria: attempted cauterization, cease of treatment, incomplete case history having complication, and not acceptance. Totally 40 patients were coincidence with the criteria including 22 males and 18 females aged from 5 to 40 years.METHODS: Mild and potent cauterization was adopted according to whether there was chronic congestion in tonsil. For patients with degree Ⅲ of tonsil hypertrophy without obvious congestion, potent cauterization with large size cautery was adopted at 700-800 ℃, if with chronic congestion,potent cauterization with large or middle size cautery at 500-600 ℃ and mild cauterization was adopted; For patients with degree Ⅱ of hypertrophy of tonsil without obvious congestion, potent cauterization with middle size cautery was adopted at 700-800 ℃, if with chronic congestion, mild cauterization with middle or small size cautery was adopted at 500-600 ℃; for patient with first degree of hypertrophy of tonsil without obvious congestion, potent cauterization with small size cautery was adopted at 600-700 ℃, if with chronic congestion, mild cauterization with small size cautery was used at 500 ℃. Cauterization of TCM was not of rather good therapeutic effect on degree Ⅰ of tonsil hypertrophy than on degrees Ⅱ and Ⅲ of hypertrophy of tonsil. Regardless of which degree of hypertrophy of tonsil and congestion, mild cauterization should be adopted at low degree of heat if there was pain radiating to the ear region or pharyngopalatine arch becoming surface-like structure. The average interval between each cauterization was 2-3 days.MAIN OUTCOME MEASURES: Size of tonsil and histological changes of patients with degrees of Ⅱ and Ⅲll tonsil hypertrophy after cauterization.RESULTS: Totally 40 patients with degrees Ⅱ and Ⅲ of tonsil hypertrophy were treated with cautery without any loss. ① Tissues were thickened after each cautery, 38 cases received only 4-10 times of cauterization, and half of the total number of the patients received 7-8 times of cauterization (9/22.5%, 9/22.5%). ② Electrocautery could reduce course of treatment to 1/4 of that of actual cautery. Degree of hypertrophy of tonsil was of no direct ratio to cauterizing times in that 22 patients with degree Ⅱ of hypertrophy of tonsil received 4-10 times of cauterization; while 18 cases of patients with degree Ⅲ of hypertrophy, 2 patients received 13 times of cauterization, the other received 7-10 times of cauterization. ③ A patch of black and brown cauterized scab was formed after each electrocautery on the surface of tonsil; superfical layer was of faveolate structure with different sized eosin dyed mesh; the deep layer was of dull grey oblique and interdigitating cord like structure with necrotic tissues without being dyed and survival lymphocyte in the space between cord, the lymphocyte had the changes of karyo pyknosis and nuclear fragmentation or disappearing of red dyed nuclear. Compared with actual cautery, cauterization of necrotic layer was obviously thickening and easy to exfoliate in electrocautery of TCM. ④ After 24 hours of cauterization, necrotic tissues migrated to normal lymphatic area presented with such inflammatory changes as vascular dilation, widening of lymphocyte space and infiltration of neutrophil. The degrees of above mentioned changes between electrocautery of TCM and actual cautery achieve no significant difference and the inflammatory changes disappeared in 4-5 days.CONCLUSION: Because of high temperature, few cauterized times and short course, electrocautery of TCM has a remarkable effect on degrees Ⅱ and Ⅲ of tonsil hypertrophy; however, various textures, degrees of hyperemia, ages and co-operations can cause different cauterized times.

Objective To improve lower eyelid blepharoplasty by using myocutaneous flap and lateral one-third skin flap.Methods A total of 37 patients were recruited in this study and received lower eyelid blepharoplasty.Incision was made at the lower palpebral margin,and the extension of incision was hided into the outer canthus rhytids.Myocutaneous flap was made first followed by the preparation of skin flap at the lateral one-third of the lower eyelid.Results All the patients experienced a quick recovery from the surgery.The excess skin at the lateral canthus was completely removed,the incision was sutured under moderate tension,and the eyelid skin was flattened.No lid-retraction or lower eyelid ectropion was observed in the 6-to 12-month postoperative follow-up.The lateral incision sear was hidden and the operation outcome was satisfactory.Conclusions The lower eyelid blepharoplasty with myocutaneous flap and lateral one-third skin flap may lead to a satisfactory outcome with the formation of natural outer canthus angle and make the patients younger.
