ABSTRACT
Objective:To analyze the factors influencing the poor effect of short-term electrical spinal cord stimulation in the treatment of postherpetic neuralgia (PHN).Methods:The medical records of PHN patients of either sex, aged 40-85 yr, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, who received short-term electrical spinal cord stimulation from July 2017 to July 2022, were retrospectively collected. The therapeutic effect was evaluated using the modified MacNab criteria at 3 months after operation, and the patients were divided into good efficacy group (excellent and good efficacy) and poor efficacy group (fair and poor efficacy). General information, disease course, lesion site, complicated diseases, ossification of the yellow ligament in the diseased spinal segment, severity of pain in the herpetic stage, standard antiviral therapy in the herpetic stage (for more than 7 days) and use of neurotrophic drugs in the herpetic stage (for more than 7 days) were collected. Multivariate logistic regression analysis was used to screen the influencing factors for the poor effect of electrical spinal cord stimulation in the treatment of PHN.Results:A total of 168 patients were eventually enrolled, among which 69 had poor curative effect, and the rate of poor curative effect was 41.1%. The results of multivariate logistic regression analysis showed that the patient′s age ( OR=2.230, P=0.015), course of disease ( OR=2.191, P=0.027), complication with diabetes mellitus( OR=8.859, P=0.010), ossification of ligamentum flavum at the same segment ( OR=6.602, P=0.019), severity of pain in the herpetic stage ( OR=5.788, P=0.038) and non-standard antiviral therapy in the herpetic stage ( OR=6.765, P=0.021) were the influencing factors for the poor effect of electrical spinal cord stimulation in the treatment of PHN. Conclusions:Age, course of disease, complication with diabetes mellitus, ossification of ligamentum flandum at the same segment, severity of pain in the herpetic stage and non-standard antiviral therapy in the herpetic stage are the factors influencing the poor effect of short-term electrical spinal cord stimulation in the treatment of PHN.
ABSTRACT
Objective Neutrophil/lymphocyte ratio (NLR) is a simple and reliable inflammation biomarker but few studies have assessed the relationship between NLR and hypertension in Chinese population. In order to evaluate how NLR is related to the incidence of hypertension, we designed a large scale prospective cohort study in an adult population. Method Participants were recruited from Tianjin Medical University's General Hospital?Health Management Centre. Hypertension?free subjects (men, 13 638;women,15 212) were followed up for a median of 2.7 years. Adjusted Cox proportional hazards regression models were used to assess relationships between the quintiles of NLR and the incidence of hypertension. Result During the follow-up period, 1 348 subjects in men and 476 subjects in women developed hypertension. The hazard ratios of hypertension incidence were evaluated in increasing NLR quintiles both in men and women. In the final multivariate models, the hazard ratios (95% confidence interval) for hypertension across NLR quintiles were 1.00 (Reference), 1.05 (0.87, 1.26), 1.02 (0.85, 1.22), 1.07 (0.90, 1.29) and 1.22 (1.03, 1.45) (P for trend=0.01), in men;1.00 (Reference), 1.11 (0.82, 1.49), 0.79 (0.58, 1.08), 1.13 (0.85, 1.52) and 1.25 (0.94, 1.66) (P for trend=0.07), in women, respectively. Conclusion This study showed that the elevated NLR levels were significantly related to an increased risk of developing hypertension in men, but not in women.
ABSTRACT
Objective To understand the relationship between dietary patterns and breast cancer and to provide a possible scientific basis for breast cancer prevention,we performed a meta-analysis in order to evaluate the current relevant literature.Method Meta-analysis was used to pool the effect of vegetable,fruit,fish and soybean dietary patterns on the risk of breast cancer.The breast cancer risk of the highest categories compared to the lowest categories of such dietary patterns was combined using fixed effect model.Searching the database (Chinese databases included CQVIP,WANFANG medicine online,CNKI and SinoMED,and English databases included PubMed,Embase,Cochrane database,Medline and Google Scholar) for articles published between January 1997 and June 2014.All statistical analyses were performed using the Stata 11.0.Result Twelve cohort studies involving 623 536 participants and 19 707 patients with brcast cancer were found to be eligible.Our results indicate that a reasonably healthy dietary pattern (which is characterized by a high consumption of vegetables,fruit,fish and soybean) is beneficial for the prevention of breast cancer.Compared to the lowest categories of such dietary patterns,relative risk (RR) of the highest categories is 0.86 (95％ CI 0.80-0.92).Conclusion A reasonably healthy dietary pattern (which is characterized by a high consumption of vegetables,fruit,fish and soybean) is beneficial for the prevention of breast cancer.
