Taking Coxsackie B3 virus cDNA labelled by Biotin as detecting probes and 25 kinds of standard enteroviruses as detected viusr, a spot nucleic acid hybridization method has been established to detect enterovirus RNA gene. The method has simple operation and its sensitivity is 50-80 TCID50 spot. Reagent is safe and stable, and may be stored for long period. pCBHⅢ/35.51 probe used has wider hibridization spectrum to enteroviruses; pCBⅢ/29 only reacts with RNA of Coxsackie B3 virus in strict condition. Consequently, the hybridization character which these probes possess is suitable to determining enlerovirus in clinical samples.

Objective To study the correlation between serum bilirubin and restenosis after stent implantation of coronary heart disease (CHD).Methods Two hundred and fourtynine patients with CHD were divided into Instent-restenosis (ISR) of CHD group and non-ISR of CHD group according to their angiography findings.Theirserum bilirubin levels were compared and correlation between serum bilirubin level and ISR of CHD was studied.Results The serum bilirubin level was significantlylower in ISRof CHD group than in non-ISR group (P ＜ 0.05),in TBIL (9.9322 ± 3.8748μmol/L) to (12.08 ±4.6679μmol/L)、DBIL (3.1744 ± 1.60μmol/L) to (3.8949 ± 1.825μmol/L)、IBIL (6.757 ±2.822μmol/L) to (8.174 ± 3.388μmol/L).Conclusions The serum bilirubinlevel is lower in CHD patients with ISR than in CHD patients with non-ISR,which is an indepent risk factor for ISR of CHD.

Objective To observe the curative effect of continuous airway positive pressure ventilation (CPAP) in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and cough syncope. Methods Forty-three hospitalized patients with OSAHS and cough syncope were collected in the Department of Respiration of Tianjin General Hospital, and analyzed the related information. They were given CPAP treatment, and were divided into good compliance group (n=26) and poor compliance group (n=17) according to CPAP compliance after a half-year treatment. The apnea hypoventilation index (AHI) and c-reactive protein (CRP) were compared before and after treatment between two groups. Results The positive correlation was found between the frequency of the cough syncope and indicators of OSAHS, such as AHI, body mass index (BMI), CRP, sleepiness score (ESS) and circumference of abdomen and neck (r=0.612, 0.431, 0.224, 0.654, 0.435 and 0.344,P<0.05). All these patients were cured after the treatment of both CPAP and medication for 1 or 2 weeks. During a half-year follow-up, the cough syncope didn’t occur in those patients of good compliance group, otherwise cough syncope still happened but with less frequency in patitents of poor compliance group. Before the treatment , there was no significant difference in AHI (45.00±15.69 vs. 48.70±16.47) and CRP (3.46± 1.15 vs. 3.38±0.72) between the two groups. After treatment, AHI (26.97±14.06 vs. 48.18±15.96) and CRP (1.56±0.76 vs. 3.18± 0.78) were significantly lower in the good compliance group than those of the poor compliance group (P<0.01). Conclusion Timely and sustained treatment of OSAHS may help reduce the incidence of cough syncope and significantly improve AHI, CRP and cough symptoms.

Objective:To study the correlation of C(-938)A single nucleotide polymorphism (SNP) in the promoter of anti-apoptosis gene Bcl-2 with the clinical biological parameters of breast cancer patients in Hebei Province. Methods:Three genotypes(AA, AC, CC) of Bcl-2 C(-938)A from 113 samples of breast cancer patients were analyzed by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method, and the results were associated with clinical biological parameters. The distribution of genotype frequency was compared between different groups. Results:When stratified for axillary lymph node metastases, the frequency of AA genotype were 26.8%, 47.8% and 52.6% and the distribution of AC+CC genotypes were 73.2%, 52.2% and 47.4% in negative group, 1-3 metastasis group, and ≥4 metastasis group. The difference between the two groups was significant (χ~2=6.337, P=0.042). Compared with the AC+CC genotypes, the OR value of AA genotype in ≥4 metastasis group was 3.041 (95%CI=1.072-8.626). The frequency of AA genotype were 30.9% and 69.1% in gradeⅠ-Ⅱ group and grade Ⅲ group, and the frequency of AC+CC genotypes were 57.9% and 42.1%. The difference between the two groups was significant (χ~2=5.055; P=0.025). Compared with the AC+CC genotypes, the OR value of AA genotype in differentiated tumors(grade Ⅲ)was 3.082 (95%CI=1.122-8.465). Stratified for estrogen receptor (ER), progesterone receptor (PR) and C-erbB2, there was no difference between the distribution of AA genotype and AC+CC genotypes (χ~2=3.005, χ~2=1.504, χ~2=1.163, P>0.05). Conclusion:The AA genotype of Bcl-2 gene C(-938)A maybe correlated with high lymph node metastasis rate and poor differentiation.

OBJECTIVE To investigate the efficacy of coblation in upper airway obstruction patients. METHODS Coblation Channeling was used in 814 obstructed nasal airway patients.Soft palate coblation with or without tonsil treatment was applied in 67 adult OSAHS patients.Coblation tonsillectomy or tonsillotomy with adenoidectomy was performed in 68 pediatric OSAHS patients.RESULTS For obstructed nasal airway patients,VAS scores of 720 (88.45 %) patients were 0 to 1 after one time treatment.Thirty-five (4.3 %) patients had second treatment,and then VAS scores dropped to 0 to 1.VAS scores of 59 (7.25 %) patients kept more than 5.For adult OSAHS patients,3 (4.5 %) patients were cured,38 (56.7 %) patients were improved, 19 (28 %) patients were effective and 7 patients were not improved.For pediatric OSAHS patient s,58 (85.29 %) patients' symptoms,such as snoring,breath difficulty, mouth breathing,or pharyngeal obstruction,were relieved and 10 (14.71%) patients' symptoms were improved. CONCLUSION Coblation is widely used in ENT patients with good results.Its advantages include easy to use, minimal invasive,safe,and much less pain.It is specially suitable for pediatric OSAHS patients.

Objective To study the features of eye wounds in subtropical mountain and bush zone so as to improve success rate of medical therapy and decrease disability rate for eye wounds. Methods The clinical data of eye wounds caused by Selfdefense War against Vietnam from No. 59 Hos-pital of PLA were analyzed. Results Monocular injuries accounted for 81.7% of eye wounds, with no statistical difference in the injuries between left eye and right eye. Eye wounds caused by shrapnel ac-counted for 82.2%, and it was the main injury factor. The rate of eye injuries complicated with other in-juries of the body was up to 75.6%. Globe wounds were the most commonly seen, with open globe wound accounting for 45.1%. Conclusion Timely and correct ophthalmological treatment can effectively re-duce the blinding rate.

Objective To investigate the potential predictors and treatment for secondary sexual dysfunction following pelvic fracture. Methods 184 patients were included in this study from multiple centers in Guangzhou city, to find the potential predictors for secondary sexual dysfunction following pelvic fracture. 76 patients were identified to be secondary sexual dysfunction, which were randomized into three treatment groups, who were given continuous low dose of tadalafil (5 mg/time)combined with oral sildenafil (50 mg/time), tadalafil (5 mg/time) only and sildenafil (50 mg/time) only respectively, and followed by evaluation of therapeutic effect according to IIEF-5 questionnaire and Sexual Encounter Profile (SEP) diaries to evaluate the effect. Results Risk factors including age and the type of pelvic fractures but not urethral injury was associated with the complication of secondary sexual dysfunction . After treatment for twelve weeks, the IIEF-5 score in A groups (18.1 ± 4.2) was significantly higher than that in B (16.4 ± 3.4) or C (16.6 ± 4.0) group (P<0.05). The positive rate of response to SEP2 and SEP3 in A group were 73.0% and 79.4% respectively, both of which were remarkably higher than those in B or C group (P < 0.05). Conclusion Secondary sexual dysfunction following pelvic fracture is associated with age and type of pelvic fractures. Continuous low dose of tadalafil (5 mg/time) combined with sildenafil (50 mg/time) provides superior effective treatment for secondary sexual dysfunction following pelvic fracture.

Objective To deeply understand the risk factors of lymphedema for patients with breast cancer after surgery. Methods The phenomenological method was applied in this study. Semi-structured interview was used to collected data from 9 female breast cancer patients with lymphedema after surgery in our hospital from June to September 2016 for generic analysis. Results The risk factors of lymphedema could be categorized into four themes:(1)choice of treatment is the primary cause:axillary lymph node dissection; radiotherapy; chemotherapy; (2)not paying enough attention to lymphedema:lacking the knowledge of lymphedema; imbalance of physical activities for the affected limb; lacking awareness of exercise and protection of the affected limb. Conclusions Axillary lymph node dissection after radical surgery for patients with breast cancer is the primary cause of lymphedema, and paying not enough attention is an important factor, especially lacking the consciousness of prevention, so the nurses should emphasize education about prevention of lymphedema after surgery for patients, to improve the consciousness of them to reduce the occurrence of lymphedema and its influence on their quality of life.
