BACKGROUNDThe incidence of atherosclerosis-related myocardial infarction can be as much as 50-fold greater in young patients with systemic lupus erythematosus (SLE) than in age-matched controls. There are several explanations for this phenomenon, all of which result in a chronic state of low-grade inflammation. Recently, the neutrophil-to-lymphocyte ratio (NLR) has been proposed as a useful biomarker of inflammation. Pulse wave velocity (PWV) is a reliable indicator of vascular damage and atherosclerosis. There is a paucity of data concerning the relationship between NLR and atherosclerosis as measured by PWV in patients with SLE. This study aimed to verify whether there is a positive correlation between NLR and PWV and to explore factors that influence PWV in young SLE patients.

METHODSA total of 90 female patients with SLE were enrolled in this cross-sectional investigation. Traditional and nontraditional cardiovascular risk factors were assessed on the same day that brachial-ankle PWV (baPWV) was examined. The patients were divided into three groups according to their mean baPWV values: patients whose mean baPWV value was lower than the first tertile were placed in Group 1; patients whose mean baPWV value was between the first tertile and the second tertile were placed in Group 2; and patients whose mean baPWV value was higher than the second tertile were placed in Group 3. SPSS 20.0 was used to perform all statistical analyses in this study. Both univariate linear regression and multivariate regression models were utilized to analyze the association between NLR and arterial stiffness.

RESULTSSystolic blood pressure, diastolic blood pressure (DBP), and triglycerides were all significantly different among Groups 1, 2, and 3 (111.90 ± 12.85 mmHg vs. 114.60 ± 12.88 mmHg vs. 129.43 ± 16.21 mmHg, P < 0.001; 68.77 ± 8.63 mmHg vs. 71.87 ± 9.77 mmHg vs. 82.57 ± 14.89 mmHg, P < 0.001; and 1.44 [0.91-2.47] mmol/L vs. 0.98 [0.78-1.26] mmol/L vs. 2.20 [0.94-3.66] mmol/L, P = 0.030; respectively), as were creatinine (57.50 [52.00-69.00] μmol/L vs. 55.50 [49.00-64.00] μmol/L vs. 64.00 [56.00-86.00] μmol/L, P = 0.045) and blood urea nitrogen (4.27 [3.79-6.22] mmol/L vs. 4.16 [3.47-4.84] mmol/L vs. 5.88 [4.04-8.19] mmol/L, P = 0.011). NLRs were significantly different among Groups 1, 2, and 3 (2.16 [1.56-3.42] vs. 3.12 [1.91-4.19] vs. 5.29 [2.63-7.25], P = 0.001). NLR, together with DBP and the SLE disease activity index, independently predicts PWV.

CONCLUSIONSThis study demonstrated that there was a positive correlation between NLR and PWV. Moreover, we found that disease activity and DBP were also positively correlated with PWV.

OBJECTIVETo investigate the relationship between NK cell count/activity and acute graft-versus-host disease (aGVHD) in patients receiving allogeneic hematopoietic stem cell transplantation (allo-HSCT).

METHODSA total of 26 patients who had undergone allo-HSCT from January to July 2015 were enrolled in this study. The NK cell count/activity in the peripheral blood of recipients on day 30 after allo-HSCT were monitored by using 4-color flow cytometry. The incidence of aGVHD in patients was evaluated by clinical manifestation combinating with related pathologic indicators, and the relationship between NK cell count/activity and aGVHD were analyzed.

RESULTSIn the aGVHD group and the no-aGVHD group, the NK cell count and activity on days 30 after allo-HSCT were 655±216 cells/µl vs 1169±372 cells/µl(P=0.002) and 7.3±3.6% vs 9.0±3.6% (P=0.008). In the II-IV grade aGVHD group and the 0-I grade aGVHD group, the NK cell count/activity were 617±220 cells/µl vs 1081±399 cells/µl (P=0.001) and 4.2±1.7% vs 8.3±3.5%(P=0.001). As compared with the 0-I grade aGVHD group, patients in the II-IV grade aGVHD group had higher relapse rate (57% vs 5%)(P=0.010) , lower 1-year progression-free survival(PFS) rate (43% vs 84%)(P=0.010).

CONCLUSIONNK cell count/activity on day 30 after allo-HSCT were closely relates with aGVHD, which may be a potential marker for aGVHD and can provide a new target for aGVHD therapy.

The key to the treatment of septic shock is to provide adequate oxygen supply and improve tissue perfusion. Lactate and central venous oxygen saturation (ScvO) are commonly used as the indices of oxygen metabolism, but tissue hypoxia may still exist even when lactate and ScvOare within the normal range. Arteriovenous difference in carbon dioxide partial pressure (COgap) can accurately reflect oxygen delivery when ScvOis in the normal range. This article reviews the advantages and shortages of lactate, lactate clearance rate, ScvO, and COgap in evaluating tissue hypoxia, in order to provide a reference for treatment and severity evaluation of septic shock.

OBJECTIVETo explore the scientific connotation of the discrepant pharmaceutical activities between the head and tail of Angelica sinensis diels (AS), an important herb extensively utilized in Chinese medicine, by the approach of transcriptome sequencing.

METHODSTen samples of AS were randomly collected in Min County, Gansu Province of China. Transcriptome sequencing of AS was accomplished in a commercial ILLumina HiSeq-2000 platform. The transcriptome of each head and tail of AS were fixed in a gene chip, and detected under the procedure of Illumina HiSeq-2000. Differentially expressed unigenes between the heads and tails of AS were selected by Shanghai Biotechnology Corporation (SBC) online analysis system, based on Gene Ontology, Kyoto Encyclopedia of Genes and Genomes and relevant bioinformatic database.

RESULTSTotally 63,585 unigenes were obtained from AS by high-throughput sequencing platform. Among which 3359 unigenes were identified as differentially expressed unigenes between the heads and tails of AS by SBC analysis system scanning. Of which 15 differentially expressed unigenes participate in the metabolic regulation of phenylpropanoid biosynthesis (PB) pathway and ferulic acid metabolites, in response to the distinguished pharmaceutical actions of the heads and tails of AS.

CONCLUSIONDifferent content of ferulic acid in the heads and tails of AS is related to the differentially expressed genes, particularly involved in the PB pathway.

OBJECTIVETo evaluate the efficacy and safety of Chinese medicine (CM) plus Western medicine (WM) in the treatment of pediatric patients with severe hand, foot and mouth disease (HFMD) by conducting a prospective, controlled, and randomized trial.

METHODSA total of 451 pediatric patients with severe HFMD were randomly assigned to receive WM therapy alone (224 cases, WM therapy group) or CM [Reduning Injection ( ) or Xiyanping Injection ()] plus WM therapy (227 cases, CM plus WM therapy group) for 7-10 days, according to a web-based randomization system. The primary outcome was fever clearance time, which was presented as temperature decreased half-life time. The secondary outcomes included the rate of rash/herpes disappearance within 120 h, as well as the rate for cough, runny nose, lethargy and weakness, agitation or irritability, and vomiting clearance within 120 h. The drug-related adverse events were also recorded.

RESULTSThe temperature decreased half-life time was 40.4 h in the WM therapy group, significantly longer than 27.2 h in the CM plus WM therapy group (P<0.01). Moreover, the rate for rash/herpes disappearance within 120 h was 43.6% (99/227) in the CM plus WM therapy group, significantly higher than 29.5% (66/224) in the WM therapy group (P<0.01). In addition, the rate for cough, lethargy and weakness, agitation or irritability disappearance within 120 h was 32.6% (74/227) in the CM plus WM therapy group, significantly higher than 19.2% (43/224) in the WM therapy group (P<0.01). No drug-related adverse events were observed during the course of the study.

CONCLUSIONThe combined CM and WM therapy achieved a better therapeutic efficacy in treating severe HFMD than the WM therapy alone. Reduning or Xiyanping Injections may become an important complementary therapy to WM for relieving the symptoms of severe HFMD. (Registration No. NCT01145664).

BACKGROUNDAngiotensin II (Ang II) is a major contributor to the development of heart failure. However, the molecular and cellular mechanisms that underlie this process remain elusive. Inadequate angiogenesis in the myocardium leads to a transition from cardiac hypertrophy to dysfunction, and our previous study showed that Ang II significantly impaired the angiogenesis response. The current study was designed to examine the role of Jagged1-Notch signaling in the effect of Ang II during impaired angiogenesis and cardiac hypertrophy.

METHODSAng II was subcutaneously infused into 8-week-old male C57BL/6 mice at a dose of 200 ng·kg-1·min-1 for 2 weeks using Alzet micro-osmotic pumps. N-[N-(3, 5-difluorophenacetyl)-L-alanyl]-S-phenylglycine tert-butyl ester (DAPT), a γ-secretase inhibitor, was injected subcutaneously during Ang II infusion at a dose of 10.0 mg·kg-1·d-1. Forty mice were divided into four groups (n = 10 per group): control group; Ang II group, treated with Ang II; DAPT group, treated with DAPT; and Ang II + DAPT group, treated with both Ang II and DAPT. At the end of experiments, myocardial (left ventricle [LV]) tissue from each experimental group was evaluated using immunohistochemistry, Western blotting, and real-time polymerase chain reaction. Data were analyzed using one-way analysis of variance test followed by the least significant difference method or independent samples t-test.

RESULTSAng II treatment significantly induced cardiac hypertrophy and impaired the angiogenesis response compared to controls, as shown by hematoxylin and eosin (HE) staining and immunohistochemistry for CD31, a vascular marker (P < 0.05 for both). Meanwhile, Jagged1 protein was significantly increased, but gene expression for both Jag1 and Hey1 was decreased in the LV following Ang II treatment, compared to that in controls (relative ratio for Jag1 gene: 0.45 ± 0.13 vs. 0.84 ± 0.15; relative ratio for Hey1 gene: 0.51 ± 0.08 vs. 0.91 ± 0.09; P < 0.05). All these cellular and molecular effects induced by Ang II in the hearts of mice were reduced by DAPT treatment. Interestingly, Ang II stimulated Hey1, a known Notch target, but did not affect the expression of Hey2, another Notch target gene.

CONCLUSIONSA Jagged1-Hey1 signal might mediate the impairment of angiogenesis induced by Ang II during cardiac hypertrophy.

OBJECTIVETo evaluate the safety and efficacy of the perineal rectosigmoidectomy (Altemeier procedure) in the treatment of full thickness rectal prolapse.

METHODSClinical and follow-up data of 52 patients with full thickness rectal prolapse undergoing Altemeier procedure in 9 hospitals from September 2010 to July 2016 were analyzed retrospectively. Of which 38 cases were from Zhongnan Hospital of Wuhan University, 1 case from Suizhou Central Hospital of Hubei province, 1 case from Jingzhou Second People's Hospital of Hubei province, 3 cases from Wuxue First People's Hospital of Hubei province, 1 case from Jingmen First People's Hospital of Hubei province, 1 case from Tuanfeng County Hospital of Hubei province, 4 cases from Jingzhou Central Hospital of Hubei province, 2 from PLA Rocket Army General Hospital, 1 case from the Affiliated Hospital of Xuzhou Medical University in Jiangsu province. Altemeier operation steps: The line shaped teeth, the prolapsed rectum is first exposed to the anus. In the dentate line proximal 1-3 cm with ultrasonic knife or Ligasure ring outer rectal incision, using electric knife to mark pre resection line in rectal mucosa. Open down in front of the pelvic peritoneum. Incision of the outer intestine and the reduction of the internal rectum and part of sigmoid colon. To free and remove excess pelvic retroperitoneal, pelvic peritoneum and be at the top of the colon or rectum anterior pelvic reconstruction suture. The rear of the levator ani muscle forming rectum. Pull gently to the anus and rectum and sigmoid, in the absence of tension, 2-3 cm outside the anus was selected as the proximal inner bowel pre resection line, along the line of pre transection of proximal bowel resection, again the broken end of intestine full-thickness end-to-end anastomosis. Postoperative complication and recurrence were summarized. Gastrointestinal quality of life index (GIQLI), Wexner constipation score and Wexner fecal incontinence score were used to evaluate the efficacy.

RESULTSAll the 52 patients were beyond moderate full thickness rectal prolapse. Thirty-one were male and 21 were female with age ranging from 22 to 83 (average 53) years. The length of prolapsed rectum was 6 to 20 (average 9) cm and course of disease was 0.5 to 46(average 19.5) years. No perioperative death. Five patients (9.6%) had postoperative complications, including 2 anastomotic bleeding, 1 wall portion dehiscence of anastomosis, 1 anastomotic stenosis, and 1 malnutrition. Recurrence rate was 9.6%(5/52) within the long-term follow-up of 5 to 71 (median 40) years. Compared with the preoperative results, Wexner constipation score and Wexner fecal incontinence score decreased obviously (2.1±1.4 vs. 4.6±3.4, 4.8±4.1 vs. 6.8±4.1), and GIQLI significantly increased from 99.6±8.0 to 103.0±9.1 (all P<0.05) at 6-month after operation. Above 3 scores were sustained and continuously improved at 12-, 24-, and 36-month during the follow-up (all P<0.05).

CONCLUSIONAltemeier procedure possesses good efficacy with low morbidity of complication and recurrence in the treatment of full thickness rectal prolapse.

Cinnabars are widely used in the clinic and shows unique efficacy, and it has been used in treating diseases for thousands of years either single-use or combination with other traditional Chinese medicines. Cinnabar mainly contains mercury, which displays obvious hepatotoxicity and nephrotoxicity. The safety of cinnabar and its rational use caused extensive attention. However, there are some misunderstanding that cinnabar shows equivalent toxicity to the toxicity of mercury compounds such as mercuric chloride and methylmercury in safety evaluation of cinnabar, which in our view exaggerates the toxicity. For traditional Chinese medicine containing cinnabar, some researchers questioned the medicinal value of cinnabar, and even proposed to remove cinnabar in order to avoid possible poisoning. This review reported adverse events, summarized its toxicity characteristics, mechanism and the medicinal value in preparations of traditional Chinese medicine. The significance of this paper is to further understand the toxicity of cinnabar and reduce its side effect in clinical application, and to provide a scientific basis for reasonable clinical application and a scientific understanding of cinnabar.

OBJECTIVETo evaluate the influence of extreme ambient temperature on mortality and years of life lost (YLL) in Chongqing.

METHODSThe daily mortality, meteorology and air pollution index data in Chongqing from the 1(st) January 2010 to the 31(st) December 2013 were collected. Distributed lag non-linear model (DLNM) was used to assess the influence of daily ambient temperature on daily number of deaths and daily YLL respectively. The delayed and cumulative effects of extreme temperature on sex, age, and cause-specific mortality were also assessed.

RESULTSThe relationships between ambient temperature and non-accidental, cardiovascular disease and respiratory disease mortalities and YLL were U-shaped or W-shaped. The effect of heat was obvious on that day, peaked on day 7, and lasted for two weeks, whereas the effect of cold was obvious a week later and lasted for a month. As 1 ℃ increase of ambient temperature, the cumulative relative risks (CRR) of high temperature across lag 0-7 days on non-accidental, respiratory disease and cardiovascular disease mortalities were 1.05 (95%CI: 1.03-1.07), 1.08 (95%CI: 1.05-1.11) and 1.05 (95%CI: 1.01-1.09) respectively. The effects of heat on YLL for each cause were 23.81 (95%CI: 12.31-35.31), 14.34 (95%CI: 8.98-19.70) and 4.43 (95%CI: 1.64-7.21), respectively. On cold days, 1 ℃ decrease of ambient temperature was correlated with an increase in CRR of 1.06 (95%CI: 1.04-1.08), 1.09 (95%CI:1.06-1.12) and 1.06 (95%CI: 1.02-1.11) from lag 0 to 14 for non-accidental, respiratory disease and cardiovascular disease mortalities, respectively. The estimated YLL were 23.34 (95%CI: 10.04-36.64), 16.39 (95%CI: 10.19-22.59) and 2.61 (95%CI: -0.61-5.82). People aged ≥65 years tend to have higher CRR and YLL than those aged <65 years. On high temperature days, the CRR in women was higher than that in men, while the YLL in women was lower than that in men. On low temperature days, both the CRR and YLL in women were higher than those in men.

CONCLUSIONSBoth high and low ambient temperature have adverse health effects. People aged ≥65 years are more sensitive to both high and low ambient temperature. Younger men are more sensitive to high ambient temperature and women and elder men are sensitive to low ambient temperature. It is necessary to take targeted measures to protect the population in Chongqing from the adverse influence of extreme ambient temperature.

OBJECTIVETo investigate the effect of premature rupture of the membrane (PROM) on neonatal complications in premature infants.

METHODSThe registration information of 7684 preterm infants with gestational age <37 weeks were collected from the cooperative units in the task group between January 1, 2014 to December 31, 2014. Specially trained personnel from each cooperative units filled in the unified form in a standardized format to record the gender, gestational age, birth weight, PROM, placental abruption, antenatal corticosteroid, Apgar score, amniotic fluid pollution, and complications of the infants. The data were analyzed comparatively between the cases with PROM and those without (control).

RESULTSThe preterm mortality rate was significantly lower but the incidences of ICH, NEC, ROP and BPD were significantly higher in PROM group than in the control group (P<0.05). The 95% confidence interval of the OR value was <1 for mortality, and was >1 for ICH, NEC, ROP and BPD. After adjustment for gestational age, birth weight, gender, mode of delivery, placental abruption, placenta previa, prenatal hormones, gestational diabetes mellitus (GDM), gestational period hypertension and 5-min Apgar score <7, the incidences of NEC, ROP and BPD were significantly different between the two groups (P<0.05) with 95% confidence interval of OR value >1, but the mortality rate and incidence of ICH were not significantly different between the two groups (P>0.05).

CONCLUSIONPROM is a risk factor for NEC, ROP and BPD in preterm infants, and adequate intervention of PROM can reduce the incidences of such complications as NEC, ROP and BPD in the infants.
