RESUMEN

Objective To analyze the clinical efficacy of the Qianyang Fengsui Dan(combined with flying needle therapy)in the treatment of kidney-yang deficiency type of insomnia.Methods A retrospective study was conducted to select 82 patients with insomnia admitted to the Department of Traditional Chinese Medicine of Dezhou Hospital of Traditional Chinese Medicine from November 2020 to November 2021,and they were divided into an observation group and a control group according to whether or not they were treated with Qianyang Fengsui Dan combined with flying needle therapy,with 41 cases in each group.The control group was treated with Estazolam,while the observation group was treated with Qianyang Fengsui Dan combined with flying needle therapy on the basis of the treatment of the control group,and the course of treatment was 1 month.The changes of Pittsburgh Sleep Quality Index(PSQI)scores and Epworth Sleepiness Scale(ESS)scores,as well as polysomnographic parameters were observed before and after treatment in the two groups.The changes of γ-aminobutyric acid(GABA),glutamate(GA),substance P(SP),and neuropeptide Y(NPY)levels were compared before and after treatment between the two groups.And followed up for 1 year to compare the incidence of relapce of the two groups of patients.Results(1)The total effective rate was 95.12%(39/41)in the observation group and 63.41%(26/41)in the control group,and the efficacy of the observation group was superior to that of the control group,and the difference was statistically significant(P＜0.05).(2)After treatment,PSQI scores and ESS scores of patients in the two groups were significantly improved(P＜0.05),and the observation group was significantly superior to the control group in improving PSQI scores and ESS scores,and the differences were statistically significant(P＜0.05).(3)After treatment,sleep efficiency,awakening time,sleep latency,REM,and total sleep time were significantly improved in the two groups(P＜0.05),and the observation group was significantly superior to the control group in improving sleep efficiency,awakening time,sleep latency,REM,and total sleep time,and the differences were statistically significant(P＜0.05).(4)After treatment,the serum GABA,GA,SP,and NPY levels of patients in the two groups were significantly improved(P＜0.05),and the observation group was significantly superior to the control group in improving the serum GABA,GA,SP,and NPY levels,and the differences were all statistically significant(P＜0.05).(5)After treatment,follow-up for 1 year,the recurrence rate of the observation group was 0,and there were 7 cases of recurrence in the control group,and the recurrence rate of the control group was 17.07%(7/41),and the recurrence rate of the observation group was lower than that of the control group,and the difference was statistically significant(P＜0.05).Conclusion The combination of flying needle therapy and Qianyang Fengsui Dan can effectively relieve insomnia and fatigue in patients with insomnia,reduce daytime drowsiness,regulate the release of blood monoamine neurotransmitters,and reduce the relapse rate,and its efficacy is superior to that of simple western medicine treatment.

RESUMEN

Intestinal Peyer's patches （PPs） are local immune tissues of the intestine， which are considered to be the main induction site of the intestinal mucosal immune response， and closely related to immune-related refractory enteropathies， such as ulcerative colitis and Crohn's disease. In recent years， more and more scholars have tried to find a new breakthrough for treating refractory enteropathies with a limited efficacy of clinical interventions through in-depth study of the relationship between PPs and enteropathy. Traditional Chinese medicine （TCM） polysaccharides are considered to be a key component for immune regulation with TCM. Modern studies show that TCM polysaccharides have a significant positive intervention effect on the structure and function of PPs， with good development prospects. Based on this， this paper focuses on PPs and intestinal-related diseases， and systematically introduces the physiological structure of PPs and their drug delivery mechanism， and summarizes the interactions of PPs with effect on immune-related enteropathies， analyze of current studies and prospects of effect of TCM polysaccharides in intervening intestinal disease and its dysfunction by regulating PPs， with the aim to provide new strategies for basic studies and clinical treatment of immune-related refractory enteropathies from the perspective of PPs， and new ideas for basic studies and clinical studies on effect of TCM polysaccharides in intervening enteropathies.

RESUMEN

We evaluate the performance of Xpert MTB/RIF for the diagnosis of extrapulmonary tuberculosis (EPTB) in China. The performance of Xpert was evaluated compared to the composite reference standard (CRS), drug susceptibility testing (DST), and imaging examination. The overall sensitivity and specificity of Xpert were 64.1% (195/304) and 100% (24/24), respectively, using CRS as the gold standard. The sensitivity was significantly higher than that of culture for pus (P<0.05). The proportion of EPTB-positive cases diagnosed by imaging was two times more than that diagnosed using Xpert; however, 6 out of 19 cases may have been overdiagnosed by imaging. Compared to phenotypic DST, the sensitivity and specificity of Xpert were 80% (12/15) and 100% (75/75), respectively. Considering its high sensitivity and specificity, Xpert MTB/RIF may be used as a rapid initial test for EPTB diagnosis, and may also support a quicker decision on the treatment regimen. The combination of imaging and Xpert testing could provide high efficiency and accurate diagnosis of suspected EPTB.

RESUMEN

<p><b>OBJECTIVE</b>To investigate the relationship of volatile sulphur compounds((VSC)levels in periodontal pockets with severity of periodontitis, and the impact of VSC on the result of initial periodontal therapy.</p><p><b>METHODS</b>Twenty-five patients with chronic periodontitis(CP)(13 males and 12 females with average age of 35) were included in this study. Clinical periodontal parameters, plaque index, probing depth(PD), attachment loss(AL), and bleeding on probing(BOP) were recorded before and 3 months after the initial therapy. VSC levels were measured with a portable monitor in a digital score ranging from 0.0 to 5.0. All of 5 054 sites for 840 teeth were included in this study.</p><p><b>RESULT</b>Before treatment the percentage of VSC-positive sites was 17.1%, 52.3% and 86.0% for shallow (PD<3 mm), moderate(PD 4-6 mm) and deep (PD>7 mm) pocket, respectively (P<0.001). In most VSC-positive sites the VSC levels were<1.0. Percentage of sites with a high VSC levels was significantly different among three groups (P<0.01). All clinical parameters in VSC-negative sites were reduced significantly following the initial therapy. The reduction of PD and AL in VSC-positive sites by treatment was less marked than that in VSC-negative sites.</p><p><b>CONCLUSION</b>VSC in periodontal pockets may be a potential indicator for detecting severity of CP and a useful predictor for therapeutic success.</p>
