  • Effect of continuous positive airway pressure on blood pressure and related inflammatory factors in patients with obstructive sleep apnea hypopnea syndrome complicated with refractory hypertension

    ObjectiveTo investigate the effects of continuous positive airway pressure (CPAP) ventilation on blood pressure and related inflammatory factors in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) and refractory hypertension, and explore the correlation between respiratory function and related inflammatory factors.MethodsPatients with OSAHS and refractory hypertension who visited Shenzhen Nanshan People’s Hospital between January 2014 and September 2018 were randomly divided into a CPAP group and a control group. The control group received routine treatment. The CPAP group received CPAP on the basis of conventional treatment. Each intervention lasted for 7 days. The changes of systolic and diastolic blood pressure were measured before and after 1, 3, 5, and 7 days, respectively. The respiratory function and related inflammatory factors were measured after 7 days of intervention.ResultsAfter 7 days of treatment in the CPAP group, the levels of apnea hyperpnoea index (AHI), lowest oxygen saturation and oxygen desaturation index were significantly better than those before intervention, with the improvement of respiratory function significantly higher than that of the control group after 7 days. Meanwhile the systolic and diastolic blood pressure levels were significantly lower in the CPAP group than those of the control group at 1, 3, 5, and 7 days, and lower than the pre-intervention after 7 days of intervention. After 7 days of intervention, the inflammatory factors in both groups were significantly improved (all P<0.05). However, the serum levels of high sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and endothelin-1 (ET-1) in the CPAP group were significantly lower than those of the control group after 7 days of treatment (P<0.05). There was a significant positive correlation between AHI level and hs-CRP, IL-6, TNF-α and ET-1 in the CPAP group after intervention (P<0.001).ConclusionsCPAP can significantly improve the blood pressure of patients with OSAHS and refractory hypertension. CPAP may improve the related inflammatory factors by improving the respiratory function of patients, thus reduce the patient’s blood pressure.

  • Effcacy Comparison between Different Treatments for Herpes Zoster Neuralgia

    ObjectiveTo compare the analgesic effect of different treatment for herpes zoster neuralgia, and optimize herpetic neuralgia treatment. MethodsWe collected hospital inpatient data with herpes zoster by the First Military Medical Case Management System between January 1st, 2009 and December 20th, 2013. All the patients were divided into five groups according to different treatments. Patients in group A accepted valaciclovir capsules and doxepin hydrochloride tablets; patients in group B accepted valaciclovir capsules; patients in group C accepted valaciclovir capsule, nefopam hydrochloride tablets and doxepin hydrochloride tablets; patients in group D accepted valaciclovir capsules and nefopam hydrochloride tablets; patients in group E accepted valaciclovir capsules and non-steroidal anti-inflammatory drugs (including nimesulide capsules and ibuprofen sustained-release capsules). We collected such statistic data as sex, age, time of onset, time of pain disappearing after treatment. Then, we analyzed the difference among the groups on the time of pain disappearing. ResultsThere were 336 cases compliant with the standard in all the 898 cases of medical record data. The number of the patients was 72, 86, 66, 60 and 52; while the pain disappearing time after treatment was (5.94±2.54), (8.60±3.09), (5.77±1.85), (5.80±1.96) and (6.86±2.18) days, respectively in group A, B, C, D and E. Pain disappearing time after treatment of group B was significantly different from groups A, C, D, and E (P<0.05); group E was significantly different from groups A, C, and D (P<0.05); there was no significant difference between group A and groups C and D, and between group C and D (P>0.05). ConclusionThe combination of nefopam hydrochloride tablets, doxepin hydrochloride tablets, nimesulide capsules, and ibuprofen sustained-release capsules is effective in the treatment of herpes zoster neuralgia. The use of nefopam hydrochloride tablets with doxepin hydrochloride tablets is more effective than the combination of nimesulide capsules and ibuprofen sustained-release capsules. Doxepin hydrochloride tablets are not significantly different from nefopam hydrochloride tablets. Nefopam hydrochloride tablets and doxepin hydrochloride tablets are not associated with increased efficacy.

  • Laparoscopic Roux-en-Y Gastric Bypass versus Laparoscopic Sleeve Gastrectomy for Obesity and Type 2 Diabetes Mellitus: A Meta-analysis

    ObjectiveTo systematically review the efficacy and safety of laparoscopic Roux-en-Y gastric bypass (LRYGB) versus laparoscopic sleeve gastrectomy (LSG) for obesity and type 2 diabetes mellitus (T2DM). MethodsWe searched PubMed, EMbase, The Cochrane Library (Issue 8, 2014), CNKI and WanFang Data from inception to December 2014, to collect randomized controlled trials (RCTs) of LRYGB vs. LSG for obesity and T2DM. Two reviewers independently screened literature, extracted data and evaluated the risk of bias of included studies. Then, meta-analysis was performed using RevMan 5.2 software. ResultsA total of 8 RCTs including 828 patients were included. The results of meta-analysis showed that:There were no significant differences between the LRYGB group and the LSG group in body mass index (MD=-1.02, 95%CI -2.90 to 0.86, P=0.29), remission rate of T2DM (OR=1.11, 95%CI 0.71 to 1.73, P=0.64), reoperation rate (OR=2.74, 95%CI 1.01 to 7.42, P=0.05), level of fasting plasma glucose (MD=2.71, 95%CI -0.80 to 6.21, P=0.13), and level of serum low density lipoprotein (MD=-23.85, 95%CI -47.20 to -0.50, P=0.05). However, the LSG group had lower postoperative complication rate (OR=2.28, 95%CI 1.43 to 3.62, P=0.000 5) than that of the LRYGB group. ConclusionIn short term, both LRYGB and LSG were equally efficient in the treatment of obesity and T2DM, but LSG has lower postoperative complication rate than LRYGB. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
