Objective:To observe adjuvant curative effect and adverse reactions of montelukast in the treatment of children with bronchial asthma and its effect on recurrence. Methods:Totally 180 cases of children with bronchial asthma were randomly divided in-to the control group and the observation group with 90 ones in each. The control group was treated with oxygen and budesonide terbutal-ine inhalation, intravenous methylprednisolone sodium succinate and the other conventional treatment methods, and the observation group was additionally treated with montelukast sodium tablets 5 mg, po, qd. The treatment course was three months, and then expira-tory dyspnea, disappearance time of asthma and wheeze and adverse drug reactions in the two groups were evaluated. After 3-6-month follow-up, the recurrence was compared between the two groups as well. Results: The disappearance time of dyspnea, asthma and wheeze in the observation group was shorter than that in the control group (P<0. 05), the total effective rate in the observation group was 96. 67%, which was significantly higher than that in the control group (73. 33%, P<0. 05). The mean follow-up duration was (5. 1 ± 0. 3) months, and the recurrence rate was 8. 51% in the observation group, which was significantly lower than that in the con-trol group (31. 43%, P<0. 05). During the treatment, no significant adverse drug reaction was appeared in the two groups. Conclu-sion:The conventional drug treatment combined with montelukast can rapidly improve the clinical symptoms and reduce recurrence with promising safety, which is worthy of clinical application.

MicroRNAs (miRNAs) are involved in cell growth,differentiation,apoptosis and tumor occurrence and play an important role in regulation.Many studies show that miRNAs can regulate the expression of target gene,which is associated closely with the occurrence,development,chemosensitivity and prognosis of colorectal cancer.Detection of miRNAs is expected to formulate more detailed individualized chemotherapy for colorectal cancer patients and improve their prognosis.

Objective To evaluate the efficacy and safety of the combination of Weimaining capsule and XELOX regimen (oxaliplatin plus capecitabine) in the treatment of advanced gastric cancer patients.Methods A total of 62 patients with advanced gastric cancer who fulfilled all predetermined criteria were randomly divided into observation group and control group.The 31 patients in observation group received a combination of Weimaining capsule and XELOX regimen,the 31 patients in control group received only XELOX regimen at the same dose intensity.Each patient received at least two cycles (1 cycle =21 days) of treatment,the efficacy was assessed after two cycles.Results The median time-to-progression (TTP) of observation and control groups were 5.5 and 4.8 months,respectively.The difference had no statistical significance (P =0.238).The disease control rates (DCR) of observation group was significantly improved compared with control group [67.7 ％ (21/31) vs 41.9 ％ (13/21),P ＜ 0.05],the difference was statistically significant,while the objective response rate (ORR) of the 2 groups had no statistical difference [(32.3 ％ (10/31) vs 25.8 ％ (8/31),P ＞ 0.05].In drug safety aspects,there was no Ⅴ grade adverse reactions (deaths caused by drug) among all the patients.Rates of grades Ⅱ-Ⅳ neutrocytopenia and nausea,vomiting in observation group were obviously lower than control group [16.13 ％ (5/31) vs 38.71％ (12/31),P ＜ 0.05;12.90 ％ (4/31) vs 35.48 ％ (11/31),P ＜ 0.05],other adverse reactions between the 2 groups had no statistical difference.Conclusions A combination of Weimaining capsule and XELOX regimen in the treatment of advanced gastric cancer patients can improve DCR significantly and reduce part of adverse reaction induced by chemotherapy with satisfactory safety.This method is worthy of application widely.

This study examined the analgesic effect of diprospan in rats with trigeminal neuralgia. Rat model of trigeminal neuralgic pain was established by loosely ligating the left infraorbital branch of the trigeminal nerve. After allodynia developed, the rats were randomly divided into 2 groups (n=20 in each): diprospan group, in which the rats received diprospan (7 mg/mL, 0.1 mL) injected to the left infraorbital foramen area; control group, in which saline (0.1 mL) was administered as the same manner as the diprospan group. The pain threshold (PT) in the left infraorbital area was measured before and 2, 6, and 8 weeks after the administration. The expression of neuropeptides [substance P, preprotachykinin A (PPTA), calcitonin gene-related peptide (CGRP)] in the trigeminal nerve was detected at the same time points as the PT measurement by immunohistochemistry or in situ hybridization method. The results showed that in the diprospan group, the PT was 10.65±1.26, 10.77±1.19 and 14.13±1.34 g 2, 6, and 8 weeks after the administration respectively, significantly higher than that before the administration (PT value: 0.36±0.11) (P<0.05 for each). In the saline group, the PT was 0.37±0.13, 0.66±0.09, 4.45±1.29 and 13.72±1.72 g before and 2, 6, and 8 weeks after the administration respectively with differences being significant between before and 6, 8 weeks after the administration (P<0.01). No significant difference existed in the PT between the diprospan group and the saline group at pre-administration (P>0.05). The PT in the diprospan group was significantly greater than that in the saline group 2 and 6 weeks post-administration (P<0.05). In the diprospan group, the expression levels of neuropeptides were significantly reduced as compared with those in the saline group 2 and 6 weeks post-administration (P<0.05). It was concluded that diprospan has an obvious analgesic effect on the trigeminal neuropathic pain partly by reducing the expression of neuropeptides in the trigeminal ganglia.

Objective To explore the clinical effect of psychological rehabilitation on dysphagia with cognitive and psychological disorders post stroke. Methods 120 stroke patients with dysphagia complicated with cognitive and psychological disorders were divided into experimental group (n=60) and control group (n=60). Both groups received neurological routine medical treatment, swallowing function rehabilitation training, feeding training and low-frequency electrical stimulation. Cognitive and psychological therapy was additionally used in the experimental group. Both groups were assessed by Kubota DrinkingWater Test, Mini-Mental State Examination (MMSE), Hamilton Rating Scale for Depression (HAMD) and Hamilton Rating Scale for Anxiety (HAMA). Results 1 month after intervention, the score of Kubota Drinking Water Test improved significantly in both groups, and was higher in the experimental group than in the control group (P<0.001).The rate of clinical improvement was higher in the experimental group than in the control group (P<0.01). The scores of MMSE increased significantly in the experimental group (P<0.001). The scores of HAMD and HAMA decreased significantly in the experimental group (P<0.01). Only the scores of HAMA decreased in the control group (P<0.05). Conclusion Swallowing function rehabilitation training combined with cognitive and psychological therapy may facilitate to improve the cognitive function and psychological state and swallowing function for dysphagia with cognitive and psychological disorders post stroke.

Objective To discuss changes of accompanying femoral artery and vein blood gas in patients with burn sep?sis. Methods The retrospective data of twenty-two patients with burn sepsis and forty-three non-sepsis patients (control) was analyzed, and changes of accompanying femoral artery and vein blood gas were compared between two groups. Results Results of femoral artery gas analysis showed that the HCO3-concentration was lower in sepsis group than that of control group. Results of femoral vein blood gas showed that the partial pressure of carbon dioxide [p(CO2)] was higher in sepsis group than that of control group;the oxygen saturation (SvO2) and HCO3-concentration was lower in sepsis group than that of control group (P<0.01). The differences between oxygen partial pressure p(O2), p(CO2), HCO3-concentration, oxygen satura?tion of femoral artery and vein blood gas were significantly higher in sepsis group than those of control group ( P<0.01). Conclusion Results of femoral vein blood gas analysis change obviously in patients with burn sepsis . The detection of accompanying femoral artery and vein blood gas is beneficial to diagnosis of burn sepsis.

Objective To explore the relationship between myc/bcl-2 and myc/p53 co-expression and the prognosis of diffuse large B-cell lymphoma (DLBCL). Methods A total of 148 DLBCL cases with the follow-up data in Shanxi Cancer Hospital from January 2010 to October 2014 were selected. The expression of myc, bcl-2 and p53 protein in paraffin samples was detected by immunohistochemistry (IHC). Results The positive expression rate of myc, bcl-2 and p53 was 35.1 % (52/148), 60.1 % (89/148) and 24.3 % (36/148) respectively in 148 patients with DLBCL. There were 37 (25.0%) cases of myc/bcl-2 co-expression, which were correlated with Hans classification (χ2= 4.749, P= 0.029), IPI score (χ2= 4.894, P= 0.027), bone marrow invasion (χ2= 4.751, P= 0.029), and efficacy evaluation (χ2= 9.14, P= 0.003). Myc/p53 co-expression was detected in 17 cases (11.5 %), which was associated with Hans classification (χ2 = 5.349, P= 0.021) andLDH level (χ2= 11.1, P= 0.001). Univariate analysis revealed that myc [overall survival (OS): χ2= 6.044, P= 0.014; progression free survival (PFS):χ2= 6.212, P= 0.013], bcl-2 (OS:χ2= 5.812, P= 0.016; PFS:χ2= 4.878, P= 0.027), p53 (OS:χ2= 20.092, P< 0.0001; PFS:χ2= 18.492, P< 0.0001), myc/bcl-2 co-expression (OS: χ2= 11.277, P= 0.001; PFS:χ2= 9.024, P= 0.003) and myc/p53 co-expression (OS: χ2=21.150, P< 0.0001; PFS: χ2 = 18.655, P< 0.0001) were the adverse prognostic factors. In addition, the survival rate of the co-expression group was lower than that of single expression group, and the survival rate of myc/p53 co-expression group was lower than that of myc/bcl-2 co-expression group. Multivariate analysis showed that among the six independent variables, including myc, bcl-2, p53, myc/bcl-2, myc/p53 and treatment regimen, p53 expression was an independent prognostic affecting factor of OS (95%CI 0.172ˉ0.763, P=0.008) and PFS (95%CI 0.172ˉ0.773, P=0.009). Conclusion Myc, bcl-2 and p53 are the poor prognostic factors in DLBCL. Myc/bcl-2 and myc/p53 co-expression have synergistic effect, indicating the poor prognosis.

Objective To prospectively investigate the association between serum uric acid concentration and the risk of brain infarction in Chinese adults.Methods In this prospective cohort study,a total of 95 738 participants (aged 18-98 years old) were included and were categorized into sex-specific quintiles according to serum uric acid concentration which were collected during 2006-2007 by health examinations.The study was followed up for an average of 4 years.We used Cox regression models to calculate hazard ratios (HR) and their 95％ confidence intervals (CI).Results (1) Higher concentrations of serum uric acid were associated with older age,obesity,higher blood pressure,higher serum concentrations of total cholesterol,triglycerides,and high sensitivity C-reactive protein,smoking,alcohol drinking,history of hypertension,hyperlipidemia and atrial fibrillation,and antihypertensive medication use.(2) The incidence of brain infarction for sex-specific quintiles were 0.84％ (33/3913),0.35％ (14/3985),0.44％(17/3888),0.54％ (21/3909),0.91％ (35/3860) in women (x2 =15.676,P =0.003) and 1.18％(180/15 238),1.26％ (191/15 170),1.11％ (170/15 323),1.45％ (221/15 216),1.82％ (277/15 236)in men (x2 =36.641,P =0.000).(3) After adjusting for potential confounders,including age,body mass index,blood pressure,fasting plasma glucose,total cholesterol,triglyceride,smoking,alcohol,and medical history of major chronic conditions and antihypertensive medication use,the HR (95％ CI) of brain infarction across serum uric acid quintiles were 2.06 (1.14-3.72),0.91 (0.45-1.84),1.00 (ref),1.11 (0.58-2.09),1.31(0.73-2.34) in women and 1.07 (0.86-1.34),1.02 (0.47-2.25),1.00 (ref),1.23(1.00-1.52),1.24(1.01-1.52) in men.Conclusions In this prospective cohort study,we find a U-shaped relationship between serum uric acid concentrations and brain infarction,a higher risk of developing brain infarction in association with low or high serum uric acid concentrations.Women with lowest or highest serum uric acid concentrations and men with higher serum uric acid concentrations are more likely to develop brain infarction.This probably because women have lower serum uric acid concentrations relative to men.Confirmation of our findings in larger cohorts with longer follow-up duration is warranted.

Objective To explore the diagnosis and surgical treatment of pulmonary sequestration in adults. Methods Clinical data of 21 cases of pulmonary sequestration whose diagnosis was confirmed by surgical biopsy in our department from March 2009 to February 2016 were retrospectively analyzed. Divided the patients into the thoracotomy group (n=9) and the thoracoscope group (n=12) according to dif-ferent surgical methods, and compared the diagnosis and surgery of the two groups. Results Among the patients, 8 cases were diagnosed as pulmonary sequestration and the remaining 13 cases were misdiagnosed,with the misdiagnosis rate of 61. 9%. Intraoperative exploration dem-onstrated that the abnormal blood vessels were originated from thoracic aorta (n=14,66. 7%),abdominal aorta (n=4,19%),phrenic artery (n=3,14. 3%) and aortic arch (n=1,4. 8%), and there were 20 cases (95. 2%) of intralobar sequestration and 1 case (4. 8%) of ex-tralobar sequestration. Patients underwent thoracotomy and patients underwent video-assisted thoracoscopic surgery were of no significant differences in operative time (P=0. 104),blood loss (P=0. 209),chest tube duration (P=0. 511),drainage volume (P=0. 135) and postoperative hospital stay (P=0. 450). All the patients recovered well after surgery. Conclusion As pulmonary sequestration lacks specific clinical manifestations,missed diagnosis and misdiagnosis are very common in patients. Chest enhanced CT and CT angiography are effective diagnostic methods at present. Both thoracotomy and VATS can achieve good therapeutic effects.
