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 provide basis for the diagnosis,treatment,prevention and control of pertussis by analyzing serological test findings and clinical features of inpatients.Methods Serological test findings (including outpatients and inpatients) of suspected cases and medical records diagnosed as pertussis (severe group and non-severe group) were analyzed in Shandong Provincial Hospital Affiliated to Shandong University from January 1,2012 to December 31,2014.This retrospective study was conducted to explore the epidemiological characteristics,clinical manifestations,image manifestations of pertussis in recent years.Results The incidence of pertussis was obviously higher in 2014 than the previous 2 years,nearly 10 times than that of 2013;summer and autumn were high-occurrence seasons;pertussis was found predominately in children under 6 years old,as 68％-80％,and the majority of them were 3 months-1 year old and 4-6 years old,and there was a notable increase in children more than 6 years old in 2014;the clinical manifestations tended to be atypical,primarily spasmodic cough (79.01％,64/81 cases),cyanosis (60.49 ％,49/81 cases),vomiting after cough (35.80％,30/81 cases),conjunctiva haemorrhage (22.22 ％,18/81 cases) apnea or heart rate decrease(9.88％,8/81 cases),and whooping cough (7.41％,6/81 cases).There were significant differences(all P ＜ 0.05) in age (t =2.940),paroxysmal cyanosis (x2 =4.505),elevated white blood cell count (x2 =4.410),and lymphocyte percentage increase(x2 =7.830) between severe group and non-severe group.There was no statistical difference in sex(x2 =0.847),season (x2 =0.178),spasmodic cough (x2 =0.097),whooping cough (x2 =0.002),conjunctiva hemorrhage (x2 =0.395),apnea (x2 =0.395) and fever (x2 =0.301) between the 2 groups (all P ＞ 0.05).Mixed infection with mycoplasma was most common.Imaging manifestations of pertussis were not specific,and they might manifest uneven density,patchy inflammatory infiltrates and atelectasis.Conclusions The morbidity of pertussis is rising and atypical cases is increasing in these years,and severe cases are seen most frequently in small infants,it is necessary to perfect the laboratory test methods and immunization strategy.

Objective To observe the clinical efficacy of acupuncture in treating Oxycodone hydrochloride-induced constipation in cancer pain patients.Method Sixty cancer pain patients with Oxycodone hydrochloride-induced constipation were randomized into a treatment group and a control group, 30 cases in each group. The treatment group was intervened by acupuncture, while the control group was by oral administration of lactulose oral solution. The therapeutic efficacies were compared after 2-week treatment, and the quality of life was evaluated before and after treatment.Result The total effective rate was 90.0% in the treatment group versus 73.3% in the control group, and the difference was statistically significant (P<0.05). The Karnofsky Performance Status (KPS) score was significantly changed in the treatment group after intervention (P<0.05). There was a significant difference in comparing the KPS score between the two groups after treatment (P<0.05).Conclusion Acupuncture can produce a significant efficacy in treating Oxycodone hydrochloride-induced constipation, and also improve the patients’ quality of life.

OBJECTIVE To investigate the antibiotic use during perioperative period in surgery after administration according to Antibiotic Drug Use Guideline.METHODS The antibiotics usage status among 462 outpatient cases in Mar 2005 and 483 cases in Mar 2006 during perioperative period in surgery were surveyed.RESULTS The preventive use rate of antibiotic medication in surgery in 2005 and 2006 were respectively 99.48% and 88.12%(P

OBJECTIVE To offer scientific basis for reasonable usage and management of antibiotics through surveying the situation and problems of antibiotics usage in surgery during perioperative period.METHODS The antibiotics usage status among 462 cases of patients during perioperative period was retrospectively analyzed.RESULTS Antibiotics were used in 460 patients.The rate of prophylactic usage was 83.26%,the rate of therapeutic one was 16.74%;the duration of postoperative prophylaxis was:80.68% of the patients were treated with antibiotics for 4 days or more,the longest one was 28 days;43.26% of the patients received single antibiotic treatment,and 44.13%,11.96%,or 0.65% of patients received 2,3 or 4 kinds of antibiotics combined therapy respectively.CONCLUSIONS Improper application of antibiotics during perioperative period needs higher level administration.

OBJECTIVE To investigate the risk factors of professional exposure among medical staff and explore the preventive strategies.METHODS The influence of factors including profession,exposure process,exposed materials,treatment process,and follow-up among 110 medical staff with professional exposure was analyzed.RESULTS The general incidence of professional exposure was 52.73%,35.45% and 6.36% for clinical doctors,nures,and workers,respectively.Among all exposure cases,we found the incidence was 62.73% for pricking wound,20% for various liquid contamination,4.55% for glass injury,2.73% for scalpel cutting,and 4.55% for other instrument related damage.The reasons leading to exposure were treatment and nursing care,surgery assistance,and instrument and materials manipulation,which accounted for 40%,31.82%,and 18.18% of total incidence,respectively.All of the exposure cases had been properly treated.None of the investigated cases had been found illed with blood derived transmitted disease caused by professional exposure.CONCLUSIONS It is critical to intensify the training of medical staff for the knowledge of professional exposure and to improve their personal protective awareness,so that the incidence of professional exposure could be reduced.

ObjectiveTo observe the effect of berneol on sodium valproate passing the blood-brain barrier in rabbits.Methods12 rabbits were randomly divided into the control group and borneol group with 6 animals in each group. All animals were treated with intravenous infusion of sodium valproate until steady state; while the rabbits of the borneol group received oral borneol. The sodium valproate concentration in serum and cerebrospinal fluid (CSF) was determined. The pharmacokinetics parameters obtained from two groups were analyzed. ResultsIn the berneol group, the mean drug concentration in CSF and area under curve increased significantly ( P<0.05) compared with those of the control group, and the time of drug reaching the peak concentration in CSF was 6 hours, the ratio of CSF to plasma also increased significantly ( P<0.05), while the blood concentration not increased.ConclusionBorneol can enhance the permeability of blood-brain barrier to sodium valproate, but has small influence on blood concentration.
