OBJECTIVE: To estimate the minimal clinically important difference (MCID) of the frequency of bowel movement for the patients with chronic severe functional constipation treated with acupuncture so as to provide the evidence for the clinical decision. METHODS: In this study, 813 patients with chronic severe functional constipation treated with acupuncture in two previous randomized controlled trials were included. Through the anchor-based method (anchored by the item 28 "satisfaction with previous treatment" of the patient assessment of constipation-quality of life [PAC-QOL]) and the distribution-based method, the MCID of the weekly frequency of complete spontaneous bowel movement (CSBM) and spontaneous bowel movement (SBM) was analyzed statistically in the patients. RESULTS: The MCID of the mean weekly frequency of CSBM and SBM was 1.3 times and 1.6 times in patients with chronic severe functional constipation treated with acupuncture, respectively. CONCLUSION The mean increase of the weekly CSMB is ≥ 1.3 times and that of SBM is ≥ 1.6 times after treatment when compared with the baseline respectively, suggesting the clinical significance.

The emergence of regular short repetitive palindromic sequence clusters (CRISPR) and CRISPR- associated proteins 9 (Cas9) gene editing technology has greatly promoted the wide application of genetically modified pigs. Efficient single guide RNA (sgRNA) is the key to the success of gene editing using CRISPR/Cas9 technology. For large animals with a long reproductive cycle, such as pigs, it is necessary to screen out efficient sgRNA

OBJECTIVE: To investigate whether craving and demographic factors to predict relapse in alcohol dependence. METHODS: This study was a prospective cohort study. From August 2017 to August 2018, 158 Han male inpatients who met the diagnositic and statistical manual disorders-fourth version(DSM-IV) alcohol dependence diagnostic criteria were recruited from three mental hospitals in China. The participants were interviewed at baseline and followed up by telephone after 3 months for assessment. The baseline assessment after the acute withdrawal period included demographic data and alcohol-related data, clinical institute withdrawal assessment-advanced revised (CIWA-Ar), withdrawal and cue-induced craving on visual analog scale (VAS), Michigan alcoholism screening test (MAST), self-rating anxiety scale (SAS), self-rating depression scale (SDS) and alcohol urge questionnaire (AUQ). According to the follow-up results, "relapse" was defined as the consumption of beverages containing ethanol at any time during the follow-up study, and "time to relapse" was defined as the number of days from the first drinking to the baseline. Whether relapse occurred and the time to relapse were the primary endpoints. Cox proportional hazard regression model was used to analyze the factors affecting the relapse of alcohol dependence. RESULTS: In the study, 158 alcohol dependence patients were finally included, age from 21 to 60 years, with the mean age of (40.31±9.14) years. The relapse rate was 63.7% three months after baseline assessment. According to Cox univariate analysis and multivariate analysis, the age (OR=0.975, P=0.030) and CIWA-Ar scores (OR=1.126, P=0.010) significantly predicted relapse. And there was no significant difference in education level, marital status, withdrawal and cue-induced craving on VAS, SAS and SDS between the relapse group and the non-relapse group (P>0.05). CONCLUSION Age and severity of alcohol-dependent withdrawal symptoms during hospitalization are significantly related to relapse for alcohol in alcohol-dependent patients. To be exact, the older age is a protective factor, that is to say, the younger patients are prone to relapse, while the risk of relapse is raised by the higher severity of withdrawal symptoms. However, neither cue-induced nor withdrawal craving can predict relapse of alcohol-dependent patients.

Objective To investigate the feasibility of 18G trocar for central venous catheterization in adults.Methods Retrospective analyzed the clinical data of 60 patients with central venous catheterization under local anesthesia.These patients were randomly divided into the control group and the observation group.Selected the internal jugular vein as the site of the puncture catheter.The control group was punc-tured by conventional puncture needle while the observation group was punctured by the 18G trocar.Results There was no statistical differ-ence between the two groups in the success rate of final puncture and catheterization(P>0.05).Compared with the control group,the suc-cess rate of guidewire insert was higher,the puncture operation time was shorter,the pain score during puncture operation was lower,and post-operative patient satisfaction was higher in the observation group.The differences of the two groups were statistically significant(P<0.05). Conclusion 18G trocar can perform central venous catheterization successfully.This method has great advantages for awake patients,and it also worked in some cases with difficult wire insertion.

Objective To explore the clinical significance of Nano-Carbon particles and 3D laparoscopy in central compartment lymph node dissection and parathyroid glands protection in treatment of cN0 thyroid cancer. Methods We conduct a retrospective analysis of sixty-five patients with cN0 thyroid cancer who were received 3D laparoscopic thyroidectomy in the last 3 years. All patients were received total resection of thyroid plus the affected side and (or) contralateral side central compartment lymph node dissection. All patients were allocated to control group (n = 32) and carbon nano-particles trace group (tracer group, n = 33). The lymph node-related indexes (including number of dissected lymph node at Ⅵ area, number of Metastatic lymph node and Frozen lymph node-positive rate at Ⅵ area), serum calcium (24 h after surgery) and PTH (48 h after surgery) were collected and compared between the 2 groups. Results Number of dissected lymph node at Ⅵ area, positive rates of intraoperative frozen-section examination of parathyroid glands and PTH (48 h after surgery) were found statistical higher in nanoparticles group than control (P < 0.05). No statistical difference were found in Number of Metastatic lymph node and serum calcium (24 h after surgery) (P < 0.05). Conclusion The clinical significance of carbon nanoparticles and 3D laparoscopy is effective and feasible for central compartment lymph node dissection and parathyroid glands protection in treatment of cN0 thyroid cancer.

Purpose of this study was to analyse the characteristics of clinical, iconographical, pathological and treatment methods of Langerhans cell histiocytosis (LCH), so as to improve the diagnosis and treatment level of this disease. The clinical data of 35 LCH patients were studied retrospectively. These patients were divided into 2 groups according to age <14 years old and ≥ 14 years old. The clinical symptoms were analysed and the signs, imageology and pathology manifestation and treatment results were evaluated. The results showed that LCH clinical manifestations were diverse and complex. Surgical treatment for patients with single system involvement of LCH was better than that of multi-system involvement of LCH (MS-LCH). For the latter, combined chemotherapy effects was better. After 3-year follow-up, 1-year OS was 94% ± 4%, 2-years OS was 91% ± 5%, 3-year OS was 86% ± 7%. 3 years OS of group <14 years old and ≥ 14 years old was 94% ± 6% and 81% ± 10% respectively. The OS of former was better than that of the later, but because a small number of cases, this difference was not statistically significant. It is concluded that LCH is easy to be misdiagnosed, the pathological biopsy is the gold standard of LCH diagnosis. The PET-CT can be of great help in identifying stages and finding lesion areas of the disease. Pulmonary Langerhans cell histiocytosis (PLCH) is more common in adult. Combined chemotherapy can improve the prognosis of the patients. The treatment methods should be choosed according to the stage and classification of disease.

Objective To evaluate the alteration of cholesterol ester fatty acids and related serum biochemical parameters in elderly patients with type 2 diabetes mellitus ( T2DM).Methods Totally 73 T2DM patients (T2DM group) and 72 healthy subjects (control group) (aged ≥60 years) who received health check-ups in Beijing Hospital from August to December in 2012 were recruited and blood samples were collected .Eleven main cholesterol ester fatty acids in serum were determined with liquid chromatography tandem mass spectrometry , and endogenous conversions by desaturases and elongases were estimated from product -to-precursor ratios .Fasting plas-ma glucose (FPG), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein (Apo) AI (ApoAI), ApoB, and high sensitivity C-reactive protein (hsCRP) were analyzed with an automatic biochemistry analyzer and the results were statisti -cally analyzed .Results CE14∶0, CE16∶1 and CE22∶6 in T2DM group were significantly lower than those in the control group ( P <0.05 ) , while no significant difference existed between other fatty acid compositions .Δ9-desaturase activity was lower in T2DM group compared with that in control group (P=0.001).After adjus-ting for age, gender, body mass index (BMI), TC, TG, and FPG, Logistic analysis showed the quartiles of CE22∶6 andΔ9-desaturase activity were associated with risk of type 2 DM, and the odds ratios were 0.27 (95%CI:0.08-0.86, Wald:4.93, P<0.05) and 0.06 (95%CI:0.01-0.22, Wald: 17.39, P<0.01), respec-tively, for comparison of the top to bottom quartile .Both CE14∶0 and CE20∶3 negatively correlated with FPG (r=-0.18, -0.17, P<0.05);CE18∶0 positively correlated with BMI and TG (r=0.25, 0.24, P<0.01) and negatively correlated with HDL-C and ApoAI (r=-0.39, -0.35, P<0.01);CE20∶3 positively correlated with BMI, with a correlation coefficient of 0.42 (P<0.01).Conclusions Several cholesterol ester fatty acids de-crease in elderly T2DM patients.CE22∶6 andΔ9-desaturase may protect against T 2DM.An appropriately balanced intake of fatty acids is helpful for the prevention of T 2DM in the elderly population .

BACKGROUNDData on the epidemiology of hypertension in Chinese non-dialysis chronic kidney disease (CKD) patients are limited. The aim of the present study was to investigate the prevalence, awareness, treatment, and control of hypertension in the non-dialysis CKD patients through a nationwide, multicenter study in China.

METHODSThe survey was performed in 61 tertiary hospitals in 31 provinces, municipalities, and autonomous regions in China (except Hong Kong, Macao, and Taiwan). Trained physicians collected demographic and clinical data and measured blood pressure (BP) using a standardized protocol. Hypertension was defined as systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg, and/or use of antihypertensive medications. BP < 140/90 mmHg and < 130/80 mmHg were used as the 2 thresholds of hypertension control. In multivariate logistic regression with adjustment for sex and age, we analyzed the association between CKD stages and uncontrolled hypertension in non-dialysis CKD patients.

RESULTSThe analysis included 8927 non-dialysis CKD patients. The prevalence, awareness, and treatment of hypertension in non-dialysis CKD patients were 67.3%, 85.8%, and 81.0%, respectively. Of hypertensive CKD patients, 33.1% and 14.1% had controlled BP to < 140/90 mmHg and < 130/80 mmHg, respectively. With successive CKD stages, the prevalence of hypertension in non-dialysis CKD patients increased, but the control of hypertension decreased (P < 0.001). When the threshold of BP < 130/80 mmHg was considered, the risk of uncontrolled hypertension in CKD 2, 3a, 3b, 4, and 5 stages increased 1.3, 1.4, 1.4, 2.5, and 4.0 times compared with CKD 1 stage, respectively (P < 0.05). Using the threshold of < 140/90 mmHg, the risk of uncontrolled hypertension increased in advanced stages (P < 0.05).

CONCLUSIONSThe prevalence of hypertension Chinese non-dialysis CKD patients was high, and the hypertension control was suboptimal. With successive CKD stages, the risk of uncontrolled hypertension increased.
