Excessive 5-year weight gain predicts metabolic syndrome development in healthy middle-aged adults

AIM:To quantitatively examine the impacts of an easyto-measure parameter-weight gain-on metabolic syndrome development among middle-aged adults. METHODS:We conducted a five-year interval observational study.A total of 1384 middle-aged adults not meeting metabolic syndrome(MetS)criteria at the initial screening were included in our analysis.Baseline data such as MetS-components and lifestyle factors were collected in 2002.Body weight and MetS-components were measured in both 2002 and 2007.Participants were classified according to proximal quartiles of weight gain(WG)in percentages(%WG≤1%,1%< %WG≤5%,5%<%WG≤10%and%WG>10%, defined as:control,mild-WG,moderate-WG and severe-WG groups,respectively)at the end of the follow-up. Multivariate models were used to assess the association between MetS outcome and excessive WG in the total population,as well as in both genders. RESULTS:In total,175(12.6%)participants fulfilled MetS criteria within five years.In comparison to the control group,mild-WG adults had an insignificant risk for MetS development while adults having moderate-WG had a 3.0-fold increased risk for progression to MetS [95%confidence interval(CI),1.8-5.1],and this risk was increased 5.4-fold(95%CI,3.0-9.7)in subjects having severe-WG.For females having moderate-and severe-WG,the risk for developing MetS was 3.6(95% CI,1.03-12.4)and 5.5(95%CI,1.4-21.4),respectively. For males having moderate-and severe-WG,the odds ratio for MetS outcome was respectively 3.0(95%CI, 1.6-5.5)and 5.2(95%CI,2.6-10.2). CONCLUSION:For early-middle-aged healthy adults with a five-year weight gain over 5%,the severity of weight gain is related to the risk for developing metabolic syndrome.

Methylation Characteristics of Perivisceral Fat Gene in Obese Rats with Phlegm-dampness Syndrome and the Effect of Wen Dan Decoction

Objective To observe the characteristics of gene methylation in obese rats with phlegm-dampness syndrome induced by the high-fat diet, and to study the effect of Wen Dan Decoction on gene methylation after the intervention. Methods Methylation sites of genes were detected by the MeDIP-seq method. Bioinformatics method was used to analyze the gene methylation characteristics of obesity with phlegmdampness syndrome and the effect of Wen Dan Decoction. Results (1) There were 3 242 methylation differential loci in dietinduced obesity with phlegm-dampness syndrome, of which 1 243 were down-regulated and 1 999 were up-regulated, involving 1 579 differential genes. GO analysis showed that "offactory receptor activity" and others were enriched. The possible signal pathways involved were "Olfactory transduction""Tuberculosis""Systemic lupus erythematosus" and "Ribosome".(2) After the intervention of Wen Dan Decoction in obesity with phlegmdampness syndrome, 4 046 different methylation loci were obtained, including 1 067 down-regulated loci and 2 979 up-regulated loci, involving 2 068 genes. GO analysis showed that "offactory receptor activity" and others were enriched. These genes involved seven signaling pathways, such as "Metabolic pathways".(3) Between diet-induced obesity with phlegm-dampness syndrome and Wen Dan Decoction intervening obesity with the phlegm-dampness syndrome, 582 common genes of methylation differential genes were obtained. After the intervention of Wen Dan Decoction, the number of GO enrichment items was more than that of obesity with phlegm-dampness syndrome, and even the same GO enrichment items involved more genes. Conclusions The phlegm-dampness syndrome of obesityinduced by diet had the characteristics of gene methylation changes, and the intervention of Wen Dan Decoction could also affect the status of gene methylation. The genes affected by Wen Dan Decoction were closely related to the methylation gene of phlegm-dampness syndrome of obesity-induced by diet but covered a wider range.

Factors Associated with Excessive Daytime Sleepiness in Obstructive Sleep Apnea Syndrome under CPAP Treatment

The purpose of this study was to assess factors associated with subjective sleep evaluation, chiefly excessive daytime sleepiness (EDS) in obstructive sleep apnea syndrome (OSAS) adult outpatients under continuous positive airway pressure (CPAP) treatment. One thousand and forty-eight OSAS outpatients (mean age: 51.4% male: 90.5%) who were treated by CPAP were consecutively collected. Age, sex, CPAP compliance (CPAP usage as their device of nights with application-time of at least 4 hours per night objectively;%usage ≥ 4 h/d), and Japanese version of the Pittsburgh Sleep Quality Index (PSQI-J) of the patients showing EDS (Japanese version of the Epworth Sleepiness Scale;JESS ≥ 11) were compared cross-sectionally with those of the patients who did not show EDS (JESS < 11). Nineteen point two % of all patients showed EDS subjectively. Two hundred one patients were classified to an EDS(+) group and an 847 patients were classified to EDS(–) group. Age and global PSQI-J scores were significantly different between the two groups. Logistic regression showed that EDS was significantly associated with global PSQI-J scores, but not with age. Among PSQI-J components, overall sleep quality, duration of sleep, sleep disturbance, and day dysfunction due to sleepiness were significantly higher in the EDS(+) group. Especially, 19.4% of patient in the EDS(+) group reported actual sleep time during the past month to be less than 5 hours/day. Although functional relationship should be further evaluated, insufficient sleep is the main factor associated with EDS in the OSAS patients under CPAP treatment.

Clinical relevance of Chinese syndrome factors and thromboelastography levels in patients with phlegm-heat and fu-organ excess syndrome

Objective:Syndrome differentiation is a unique part of traditional Chinese medicine(TCM).Syndrome factors play an important role in the diagnosis and treatment of TCM syndromes.Thromboelastography(TEG)intuitively reflects the blood status of patients with acute ischemic stroke(AIS)and is important in the treatment and prognosis of AIS.To identify the relationship between TCM syndrome factors and TEG in AIS patients and standardize TCM syndrome differentiation and treatment objectives,we designed a prospective cohort study of 103 AIS patients.Methods:We used the diagnostic criteria for AIS in the Chinese Guideline for Diagnosis and Management of Acute Ischemic Stroke 2010.Diagnosis of phlegm-heat and fu-organ excess syndrome was based on the TCM Scale for the Syndrome of Phlegm-heat and fu-organ Excess.The ischemic Stroke TCM Syndrome Factor Diagnostic Scale was used to identify and diagnose syndrome factors.General information,scores of syndrome factors and values of TEG parameters of all enrolled patients were recorded.Results:There were significant differences in internal fire and phlegm-dampness scores between patients with and without phlegm-heat and fu-organ excess syndrome(P<.05).In patients with phlegm-heat and fu-organ excess syndrome,internal fire was negatively correlated with TEG parameters R and K(P<.05)and positively correlated with alpha Angle and coagulation index(P<.01).There were no significant correlations between the two syndrome factors and MA(P Z.058)and LY30(P>.05)or between both syndrome factors and TEG parameters in patients without phlegm-heat and fu-organ excess syndrome.Conclusion:The syndrome factor internal fire is a potential predictor of increased platelet function and fibrinogen activity in AIS patients with phlegm-heat and fu-organ excess,and a potentially important predictor of blood hypercoagulability in TCM.

Severe Ectopic Cushing’s Syndrome Due to ACTH-Secreting Pheochromocytoma

We report a new case of ectopic Cushing’s syndrome caused by an ACTH-producing pheochromocytoma. A 55-year-old woman presented with a history of severe proximal muscle weakness, polyuria, progressive virilization, anxiety, dyspnea on exercise, difficult to treat hypertension, and type 2 diabetes mellitus since 4 months. The laboratory data demonstrated ACTH-dependent hypercortisolism. The abdominal computed tomography scan showed a 30 mm well-defined mass in the left adrenal gland suggestive for pheochromocytoma. The adrenal veins were sampled, with intraprocedural cortisol measurement, to dosing selective ACTH and cathecolamines. The results established clearly the left adrenal gland as the source of ACTH overproduction. A left sided adrenalectomy was performed with subsequent resolution of Cushing’s syndrome. The patient was discharged in good clinical condition.

Study on the correlation between CD80/CD163 and clinical prognosis and the syndrome differentiation in patients with colorectal cancer

Background:To analyze the expression of cluster of differentiation 80(CD80)/cluster of differentiation 163(CD163)in colorectal cancer(CRC)patients and their correlation with the syndrome of traditional Chinese medicine,pathology and prognosis.Methods:(1)The correlation between the pathological characteristics of 232 postoperative CRC patients and the deficiency and excess syndromes of traditional Chinese medicine was analyzed using the chi-square test,Spearman’s correlation,and Cox regression methods.(2)Immunohistochemistry and quantitative real-time PCR were used to detect the expression of CD80 and CD163 in cancer and paracancer tissues of CRC patients.(3)The relationships between the changes of CD80 and CD163 and the prognosis of CRC patients with deficiency syndrome.Patient survival were analyzed using cardinality and Cox regression proportional-hazards model regression.Results:(1)The degree of differentiation and tumor node metastasis stage of CRC were statistically different between patients with deficiency and excess syndromes(P<0.05);carcinoembryonic antigen and carbohydrate antigen 19-9 were highly expressed in the excess syndrome group,and both were significantly correlated with the distribution of traditional Chinese medicine syndromes(P<0.001);deficiency and excess syndromes,and carbohydrate antigen 19-9 were all independent factors affecting the postoperative survival of CRC patients.(2)The distribution of post-operative survival in CRC patients was significantly correlated with the distribution of the disease type(P<0.001).(3)The expression levels of CD163 protein and message RNA were significantly higher in CRC cancer tissues than in paraneoplastic tissues(P<0.001);whereas the expression of CD80 was significantly higher in paraneoplastic tissues than in cancer tissues(P<0.001).(4)The expression levels of CD80/CD163 were significantly different in different parts of the tissues of patients with deficiency and excess syndromes(P<0.001).(5)CRC patients with high CD80 expression and low CD163 expression had longer survival cycles(P<0.001).Conclusion:The malignant progression of CRC patients with deficiency syndrome is faster than that with excess syndrome.The correlation between deficiency and excess syndromes and the expression levels of CD80 and CD163 could be an independent risk factor for the survival prognosis of patients with CRC.

“胃家实”之阳明下利刍议

阳明病之提纲证见于《伤寒论》第180条:“阳明之为病,胃家实是也。”现行教材中的胃家实同时囊括了阳明热证及阳明腑实证,这让大便秘结成为阳明病之主症,而下利则常被看作热结旁流,或被划为太阴病范畴,进而忽视了阳明下利的证治。阳明为病,燥而生热伤津,可影响人体津液的敷布,津液过多则利,过少则秘;阳明不降,则肠腑壅盛而不畅,降甚则利,不降则秘。无论下利还是便秘,均属于胃家实,由于其壅盛状态较其他下利更为明显,正邪交争较为剧烈,便可称为阳明下利证。因此,阳明病亦可出现与太阴病相类似的下利,治疗时有时需温,有时需下,临床需谨慎辨之。

Effect of Electro-acupuncture on Expression of IRS-1/PI3K/GLUT4 Pathway in Ovarian Granulosa Cells of Infertile Patients with Polycystic Ovary Syndrome-Insulin Resistance of Phlegm-Dampness Syndrome

Objective:To evaluate the effect of electro-acupuncture(EA)in infertile patients with phlegmdampness polycystic ovary syndrome-insulin resistance(PCOS-IR).Methods:Seventy-six PCOS-IR patients who underwnet in vitro fertilization and embryo transfer(IVF-ET)were equally assigned to two groups according to a random digital table:the EA group and the control group,with 38 cases in each group.Before undergoing IVF,the two groups were treated with EA or pseudo-acupuncture,respectively,for 3 menstrual cycles.The intervention was 25 min twice a week until the day of oocyte collection.The selected acupoints were Zhongwan(RN 12),Tianshu(ST 25),Daheng(SP 15),Daimai(GB 26),Qihai(CV 6),Guanyuan(CV 4),and bilateral points including Xuehai(SP 10),Fenglong(ST 40),Zusanli(ST 36),and Yinlingquan(SP 9).Evaluation of phlegm-dampness syndrome score and IR score were carried out before and after treatment.Additionally,the number of oocytes retrieved,transplantable embryo rate,high-quality embryo rate,clinical pregnancy rate and live birth rate were compared between the two groups.Real-time polymerase chain reaction analysis was used to monitor the m RNA expression of the insulin receptor substrate(IRS-1),phosphatidylinositiol 3-kinase(PI3 K)and glucose transport factor 4(GLUT4)in ovarian granulosa cells.Results:EA treatment reduced the phlegm-dampness syndrome score as well as the IR scores compared with the control group(P<0.05).No significant differences in the number of oocytes retrieved and clinical pregnancy rate between the two groups(P>0.05).Moreover,the transplantable embryo rate[49.0%(284/580)vs.41.9%(273/652)],high-quality embryo rate[36.6%(104/284)vs.27.8%(76/273)],and live birth rate[50%(19/38)vs.26.3%(10/38)]in the EA group were significantly higher than in the control group(P<0.05).Gene expression analyses revealed significantly elevated IRS-1,PI3 K and GLUT4 m RNA in ovarian granulosa cells of the EA group compared with the control group(P<0.05).Conclusions:EA may ameliorate the effects of phlegm-dampness syndrome and ovarian IR in PCOS-IR patients.Mechanistically,this effect might be through an upregulation of the IRS-1/PI3 K/GLUT4 signaling pathway,which may result in improved oocyte quality and embryonic development potential.(Registration No.Chi CTR1800015453)

Correlation of Epworth Sleepiness Scale with multiple sleep latency test and its diagnostic accuracy in assessing excessive daytime sleepiness in patients with obstructive sleep apnea hypopnea syndrome

Background Excessive daytime sleepiness （EDS） is often associated with obstructive sleep apnea hypopnea syndrome （OSAHS） and contributes to a number of comorbidities in these patients. Therefore, early detection of EDS is critical in disease management. We examined the association between Epworth Sleepiness Scale （ESS） and multiple sleep latency test （MSLT） and diagnostic accuracy of ESS in assessing EDS in OSAHS patients. Methods The ESS, MSLT and overnight polysomnography were administered to 107 Chinese patients to assess EDS and its correlations with polysomnographic parameters. The diagnostic accuracy of ESS in classifying EDS （mean sleep latency （MSL） 〈10 minutes） was evaluated by calculating the area under ROC curve. Results As the severity of OSAHS increased, MSL decreased with increase in ESS score. Conversely, patients with worsening EDS （shorter MSL） were characterized by advanced nocturnal hypoxaemia and sleep disruption compared to those with normal MSL, suggesting EDS is associated with more severe OSAHS. There was a negative correlation between ESS score and MSL and both moderately correlated with some polysomnographic nocturnal hypoxaemic parameters. The area under ROC curve of ESS for identifying EDS was 0.80 （95% CI： 0.71 to 0.88） and ESS score 〉12 provided the best predictive value with a sensitivity of 80% and specificity of 69%. Conclusion The ESS score moderately correlates with MSL and our ROC study supports ESS as a screening strategy for assessing EDS in OSAHS.

Study on the Resolving Phlegm Effect of D-Limonene in Mice with Spleen Deficiency and Phlegm-Dampness Syndrome

Objective:According to Traditional Chinese Medicine theory,spleen deficiency and phlegm-dampness syndrome(SDPDS)are caused by abnormal water metabolism in the body because of spleen dysfunction.The purpose of this article was to evaluate the efficacy of D-limonene(DL)in resolving phlegm in mice with SDPDS from the perspective of regulating the level of aquaporin 3(AQP3).Methods:The model of SDPDS was induced in mice using the multifactor modeling method,which combines internal and external dampness.An artificial climate box was used to create a humid environment,whereas the irregular diet was caused by different feeding methods on odd-even days.The mice were divided into blank control,model group,DL low-dose,DL high-dose,and positive groups.The mice were modeled and treated for 7 day.Levels of gastrin and amylase(AMS)in the serum,mucus secretion in the trachea,and AQP3 in the tissue near the gastric cardia.Results:DL significantly reduced mucus secretion in the trachea(P<0.001).It also increased the level of AMS in the serum(P<0.01)and decreased the level of AQP3 in the gastric tissue(P<0.01).Conclusions:Mice with SDPDS exhibited disturbed water metabolism and significantly increased AQP3 levels.DL can restore the levels of AQP3 and plays an important role in resolving phlegm.This study may also help expand the efficacy of natural drugs containing DL and improve the utilization of natural drug resources.
