Objective To investigate the influence of pre-administration of flurbiprofen on the hyperalgesia after remifentanil anesthesia.Methods This study included a total of 96 patients with abdominal surgery in the department of general surgery of our hospital.According to the random number table method,they were divided into 4 groups (n =24).Flurbiprofen axetil 1.5 mg/kg was injected intravenously before anesthesia in groups A1 and A2,flurbiprofen axetil was not injected in-travenously before anesthesia in groups B1 and B2.Anesthesia was maintained with infusion of remifentanil 0.1 μg·kg-1 ·min-1 in groups A1 and B1 0.4 μg·kg-1 ·min-1 in groups A2 and B2. The spontaneous breathing recovery time, consciousness recovery time,extubation time and anesthesia recover period of nausea,vomiting,restlessness and pain VAS scores were recorded. Results There was no significant difference in breath recovery time,consciousness recovery time and extubation time between the four groups.VAS score (9.0±1.8)was the highest in group B2,VAS score was significantly higher than the other three groups (P <0.05).VAS score (3.1±1.1)was the lowest in group A1, which was significantly lower than the other three groups (P < 0.05 ). Conclusion Pre-application of flurbiprofen 1.5 mg/kg can reduce postoperative hyperalgesia after remifentanil anesthesia in patients undergoing abdominal surgery.

Objective Idiopathic pulmonary fibrosis ( IPF) is a chronic inflammatory disease with unknown etiology and is lack of effective therapy. The aim of this study is to explore the function of Ca2+ and PI3K/AKT/mTOR pathway in the pathogenesis of IPF, and the impact of 1,25?( OH) 2 D3 on Ca2+ and PI3K/AKT/mTOR pathway in type Ⅱalveolar epithelial cells of rat with IPF. Methods 150 male SD rats were randomly divided into 2 groups: prevention group ( control groupⅠ, model groupⅠ, medication groupⅠ) and treatment group ( control groupⅡ, model groupⅡ, medication groupⅡ) . The tracheal exposure surgery was operated in control groupⅠ/Ⅱ, and then 200μL sterile physiological saline was administered by intraperitoneal injection of each rats 2 days and 14 days after surgery, separately. Bleomycin(BLM)(5 mg/kg) was in?jected into the trachea of model groupⅠ/Ⅱ, and then vitamin D3 solvent(0.1%ethanol and 99.9%glycol propylene, 1μL/g) was ad?ministered by intraperitoneal injection 2 days and 14 days after surger?y, separately. Bleomycin( BLM) ( 5 mg/kg) was injected into the tra?chea of medication groupⅠ/Ⅱ, and then 1,25?( OH) 2 D3( 2μg/kg) was administered by intraperitoneal injection 2 days and 14 days after surgery, separately. IPF model was built by injecting Bleomycin into the trachea of rats, 1,25?(OH)2D3(2μg/kg) was used to prevent and treat IPF by intraperitoneal injection in medication group. The hydroxyproline content of lung tissue in each group was measured, type Ⅱalveolar epithelial cells were separated from lung tissue and labeled with Fluo?3AM, then concentration of Ca2+ was detected by Laser scanning confocal microscope. The mRNA levels of PI3K, AKT and mTOR in the typeⅡalveolar epithelial cells were tested by RT?PCR. Results Compared with control groupⅠ/Ⅱ at each time point, hydroxyproline content of lung tissue, Ca2+ concentration and expression of PI3K, AKT and mTOR in typeⅡalveolar epithelial cells in model groupⅠ/Ⅱand medication groupⅠ/Ⅱwere sig?nificantly raised( P<0.05 or P<0.01) , but these were significantly reduced in medication groupⅠ/Ⅱcompared with model groupⅠ/Ⅱ( P<0.05 or P<0.01) . Correlation analysis showed that there is significant positive correlation between Ca2+ concentration and mRNA expression levels of PI3K, AKT and mTOR in model groupⅠ/Ⅱ(r=0.5988, r=0.6230, r=0.6603,P<0.01)and medication groupⅠ/Ⅱ( r=0.701 2, r=0.632 3,r=0.740 3,P<0.01) . Conclusion The PI3K/AKT/mTOR pathway plays an important role in devel?opment of IPF. 1,25?( OH) 2 D3 is able to reduce Ca2+concentration in typeⅡalveolar epithelial cells and inhibit the PI3K/AKT/mTOR pathway, and then inhibit the development of IPF.

Non-coding RNAs ( ncRNA ), including ribosomal RNA( rRNA), transfer RNA( tRNA), MicroRNA ( miRNA), long noncoding RNA(lncRNA) and small nucleolar RNA(snoR-NA), are a class of RNA that have multiple functions and are not translated to proteins. MicroRNA and lncRNA are involved in the injury, remodeling and aging of blood vessels, and it is necessary to understand the regulatory roles of MicroRNA and lncRNA in these processes. It is reported that MicroRNA and lncRNA are not only participated in the regulation of oxidative response, inflammation, cell proliferation and migration, and phenotype transition, they are also involved in the regulation of gene expression by conducting different mechanisms, including transcriptional regulation, post-transcriptional modification and chromatin remodeling. These aspects of regulation by MicroRNA and lncRNA are related to cardiovascular diseases, such as ath-erosclerosis, hypertension, myocardial infarction, stroke, pul-monary hypertension and diabetes, and thus provide a new way for genetic diagnosis and therapy of cardiovascular diseases.

OBJECTIVETo study the relationship between fetomaternal cellular traffic and hepatitis B virus (HBV) intrauterine infection.

METHODSMaternal DNA and fetal DNA were amplified by short tandem repeat (STR)-polymerase chain reaction (PCR), allele-specific PCR (As-PCR) and heminested PCR (hemi-nPCR). Cell transfer from mother-to-fetus or fetus-to-mother was determined by detecting the existence of TH01, GSTM1 and ACE. The relationship between cell transfer from mother-to-fetus and HBV intrauterine infection was analyzed by nested case-control study.

RESULTS26 of the 42 informative mother-baby pairs indicated mother-to-fetus cell traffic, 32 of the 40 informative mother-baby pairs indicated fetus-to-mother cell traffic and two-way cell traffic occurred in 10 mother-baby pairs. Statistical analysis demonstrated that the mother-to-fetus instead of fetus-to-mother cell traffic presented the association with HBV intrauterine infection. There was no significant correlation between mother-to-fetus cell traffic or the fetus-to-mother cell traffic. Both mother-to-fetus cell traffic and PBMC HBV DNA positivity appeared in pregnant women were risk factors of HBV intrauterine infection but the two did not manifest the interaction. The positive risk factors of positivity PBMC HBV DNA in newborns would included mother-to-fetus cell traffic and PBMC HBV DNA in pregnant women, also did not display the interaction.

CONCLUSIONThe cell traffic from HBsAg positive mother to fetus had more contribution to HBV intrauterine infection, which was possibly one of the HBV routes of intrauterine infecting.

Surgical intervention is the first choice treatment for intertrochanteric fractures that are common in clinical practice. Cephalomedullary nailing with two parts inserted respectively into the femoral medullary cavity and femoral head has been the mainstream protocols for the elderly patients with intertrochanteric fracture, but insertion of the cephalomedullary nail may likely lead to the outward displacement of the femoral shaft and the inversion and rotation of the head and neck bone mass, namely the so-called wedge effect. However, few reports have dealt with how to prevent the wedge effect and reduce the complications it may cause such as coxa vara deformity. The present review expounds and analyzes the concept, biomechanical mechanism, influencing factors, measurements, and prevention methods of the wedge effect, hoping to help the surgeons who try to avoid the wedge effect in surgical treatment.

OBJECTIVETo identify a novel HLA-DRB1 allele in Chinese.

METHODSA novel HLA-DR allele was detected by PCR-SSP and SBT in a patient with leukemia.

RESULTSThe sequence of the novel allele was different from all other known alleles. The novel allele differed from the closet matching allele HLA-DRB1*1404 by one nucleotide substitution in exon 2, at position 33 T>C, this resulted in an amino acid change from Tyr to His at codon 17.

CONCLUSIONThe novel allele is confirmed as a new HLA allele and it was officially named HLA-DRB1*1461 by WHO Nomenclature Committee in May, 2006.

Objective To study the application effect and significance of clinical nursing pathway (CNP)on patients with gastrointestinal polypus.Methods A total of 100 patients with gastrointestinal polypus were randomly divided into tow groups,observation group and control group,each group has 50 patients.Control group were treated with routine care and observation group were treated with clinical nursing pathway table by nurse-in-charge and the nurse on duty.To analyze the the days the patients stayed and the hospital expenses,evaluate the patients'master level of health knowledge,and investigate patient satisfaction.Results The days that the patients stayed and the hospital expenses of observation group was much lower than control group,but the master level of health knowledge and patient satisfaction was higher than control,and the differences were statistically significant(P<0.05).Conclusions CNP can shorten the days that the patients stayed,reduce hospital expenses,standardize medical care conduct,enhance communications between nurse and patient,improve patient satisfaction and healthy education effect and avoid medical tangle,all of the above has very strong clinical practicability.

OBJECTIVETo evaluate the clinical effects of Fu Fang Ya Tong Ding on treatment of gingivitis and pericoronitis.

METHODS120 clinical patients with gingivitis or pericoronitis were randomly divided into 3 groups (40 patients in each group). After routine rinse treatment for all patients, patients in the test group were treated with Fu Fang Ya Tong Ding, patients in the positive group were treated with iodine glycerol, while that time patients in the negative group received no treatment anymore. Ten minutes after treatment, visual analogue scale (VAS) was used to record the severity of pain for each patient. 3 days and 7 days later, pain and inflammation degree were also recorded by pain three-degree scoring method and index of gingivitis. The total treatment effects were evaluated under a comprehensive clinical treatment standard.

RESULTS10 minutes after treatment, 40.0% of patients in the test group had almost no pain, while no obvious reduction of pain was found in the control group. 3 days, 7 days after the treatment, 92.5%, 95.0% of patients in the test group had no pain, and 55.0%, 90.0% of patients in the positive group had no pain. In the negative group, there were 47.5% of patients which pain was still remained in 7 days. 7 days after treatment, gingival index in the test group reduced by 25.0% and 42.8% compared with the positive and negative groups (P<0.05). 3 days after treatment, 62.5%, 45.0% and 30.0% patients separately in the test, positive and negative groups manifested good effects under the comprehensive clinical treatment standard; after 7 days, 97.5%, 92.5% and 77.5% patients in the 3 groups manifested good effect. The group using Fu Fang Ya Tong Ding had better effects than groups using iodine glycerol or only applying routine rinsing treatment group (P<0.05).

CONCLUSIONFu Fang Ya Tong Ding can treat gingivitis and pericoronitis through significantly reducing inflammation and pain.
