BACKGROUNDLeakage of the intestinal mucosal barrier may cause translocation of bacteria, then leading to multiorgan failure. This study hypothesized that rhubarb monomers might protect the gut mucosal barrier in sepsis through junction proteins.

METHODSHealthy male Sprague-Dawley rats (weighing 230-250 g) under anesthesia and sedation were subjected to cecal ligation and perforation (CLP). After surgical preparation, rats were randomly assigned to eight groups (n = 6 or 8 each group): sham group (Group A: normal saline gavage); sepsis group (Group B: normal saline gavage); Group C (intraperitoneally, dexamethasone 0.5 mg/kg) immediately after CLP surgery; and rhubarb monomer (100 mg/kg in normal saline)-treated groups (Group D: rhein; Group E: emodin; Group F: 3,8-dihydroxy-1-methyl-anthraquinone-2-carboxylic acid; Group G: 1-O-caffeoyl-2-(4-hydroxy-O-cinnamoyl)-D-glucose; and Group H: daucosterol linoleate). Animals were sacrificed after 24 h. Intestinal histology, lactulose, mannitol concentrations were measured, and zonula occludens (ZO)-1, occludin and claudin-5 transcription (polymerase chain reaction), translation (by Western blot analysis), and expression (by immunohistochemistry) were also measured.

RESULTSIntestinal histology revealed injury to intestinal mucosal villi induced by sepsis in Group B, compared with Group A. Compared with Group A (0.17 ± 0.41), the pathological scores in Groups B (2.83 ± 0.41, P < 0.001), C (1.83 ± 0.41, P < 0.001), D (2.00 ± 0.63, P < 0.001), E (1.83 ± 0.41, P < 0.001), F (1.83 ± 0.75, P < 0.001), G (2.17 ± 0.41, P < 0.001),and H (1.83 ± 0.41, P < 0.001) were significantly increased. Lactulose/mannitol (L/M) ratio in Group B (0.046 ± 0.003) was significantly higher than in Group A (0.013 ± 0.001, P< 0.001) while L/M ratios in Groups C (0.028 ± 0.002, P< 0.001), D (0.029 ± 0.003, P< 0.001), E (0.026 ± 0.003, P< 0.001), F (0.027 ± 0.003, P< 0.001), G (0.030 ± 0.005, P< 0.001), and H (0.026 ± 0.002, P< 0.001) were significantly lower than that in Group B. ZO-1, occludin and claudin-5 transcription, translation, and expression in Group B were significantly lower than that in Group A (P < 0.001), but they were significantly higher in Groups C, D, E, F, G, and H than those in Group B (P < 0.05).

CONCLUSIONRhubarb monomer treatment ameliorated mucosal damage in sepsis via enhanced transcription, translation, and expression of junction proteins.

OBJECTIVETo explore the clinical efficacy of GEMOX regimen on patients with refractory non-hodgkin's lymphoma.

METHODSEighty-two cases of non-Hodgkin's lymphoma were divided into 2 groups: gemcitabine+oxaliplation(Gem+Oxa) group (42 cases) and vinorelbine+oxaliplatin(Vin+Oxa) group (40 cases) according to chemotherapy regimens. The clinical efficacy, side effects, progression-free survival situation in 2 groups were compared.

RESULTSThere was no significant difference on the clinical effects of 2 groups (P>0.05); The therapeutic efficacy for B cell lymphoma was higher than that for T cell lymphoma(P<0.05); The therapeutic effects for I-II stages was lower than that for III-IV stages(P<0.05); The incidences of platelet decline, nausea and vomit, peripheral nerve symptoms in Gem+Oxa group were lower than those in Vin+Oxa group(P<0.05); There was no significant difference in the median progression free survival(P>0.05).

CONCLUSIONThe efficacy of GEMOX regimen for refractory non-Hodgkin's lymphoma has been confirmed to be good, it has distinct clinical curative effect, it can prolong the progression-free survival time in patients with B cell lymphoma, specially for III-IV stages. It can be used as the preferred method for the treatment of patients with refractory NHL.

OBJECTIVE: To assess the clinical effectiveness of acupoint application (AP) of Guan Xin Su He Pill (, GXSHP) for patients with chronic stable angina pectoris (CSAP). METHODS: This study was carried out in 3 local hospitals in Chengdu, China. After baseline evaluation, eligible patients were randomly assigned to the placebo application for acupoints (PAA) group or the herbal application for acupoints (HAA) group. Patients in the HAA group underwent AP with herbal powder, which was mainly GXSHP, and patients in the PAA group underwent AP with sham drugs. For each treatment session, unilateral acupoints including Neiguan (PC 6), Danzhong (RN 17), Xinshu (BL 15) and Jueyinshu (BL 14), were stimulated for both groups. AP was performed 3 times a week with a 2-day interval for 4 weeks. The primary outcome was the frequency of angina pectoris attacks per week, while the secondary outcomes included angina pain intensity measured by the Visual Analogue Scale (VAS), dose of rescue oral drugs (nitroglycerin), scores on the Seattle Angina Questionnaire (SAQ), Self-Rating Anxiety Scale scores (SAS) and Self-Rating Depression Scale scores (SDS). Clinical outcomes were measured at week 0, 4 and 8. The safety of AP of GXSHP treatment for CSAP were assessed. RESULTS: A total of 121 patients were enrolled. Baseline characteristics were comparable across the 2 groups. After treatment, the angina attack numbers in the HAA group were significantly reduced from 11.00 to 4.81 (P<0.05). While, for PAA group, the angina frequency was not significantly improved (baseline 10.55; post-treatment 11.05). The HAA group had significantly fewer angina attacks than the PAA group (P<0.05). Pain intensity measured by VAS in HAA group was significantly reduced from 4.06 to 3.02 (P<0.05). While, for PAA group, the VAS was significantly increased (baseline 3.62; post-treatment 3.96; P<0.05). Clinical outcomes showed better improvement after treatment in the HAA group than in the PAA group in terms of oral administration of rescue drugs, SAS, SDS and SAQ scores (P<0.05). The adverse events were also reported. CONCLUSION AP of GXSHP is a safe and effective treatment for CSAP patients (Registration No. NCT02029118).

Objective: To establish reference values for carotid intima-media thickness (CIMT) of adult dwellers in Shenzhen City. Methods: The study was conducted based on the Shenzhen heart failure epidemiological survey from 2021 to 2022. In this survey, residents aged 18 years and above in Shenzhen were selected by using a multi-stage stratified random sampling method. General information, cardiovascular disease (CVD) related behavior and carotid ultrasound examination and etc. were collected from the participants. People with CVD factors, a history of atherosclerotic cardiovascular disease, carotid plaque or having no carotid ultrasound examination results were excluded. The parameter regression model based on fractional polynomial was used to establish the reference values of CIMT by age and sex. Results: A total of 2 163 healthy individuals were enrolled in the final analysis, including 576 males (26.6%) and 1 587 females (73.4%). The fractional polynomial regression of the CIMT mean and standard deviation was obtained. For men, the regression was mean_CIMT=0.324 7+0.006 9×age and SD_CIMT=0.076 9+0.001 2×age. For women, the regression was mean_CIMT=0.354 9+0.005 4×age and SD_CIMT=0.041 6+0.002 0×age. Conclusion: The age and sex reference values for CIMT of adult people in Shenzhen established in this study could provide the latest reference standards for early screening of subclinical CVD.

BACKGROUNDGlobally, the proportion of child deaths that occur in the neonatal period remains a high level of 37-41%. Differences of cause in neonate death exist in different regions as well as in different economic development countries. The specific aim of this study was to investigate the causes, characteristics, and differences of death in neonates during hospitalization in the tertiary Neonatal Intensive Care Unit (NICU) of China.

METHODSAll the dead neonates admitted to 26 NICUs were included between January l, 2011, and December 31, 2011. All the data were collected retrospectively from clinical records by a designed questionnaire. Data collected from each NICU were delivered to the leading institution where the results were analyzed.

RESULTSA total of 744 newborns died during the 1-year survey, accounting for 1.2% of all the neonates admitted to 26 NICUs and 37.6% of all the deaths in children under 5 years of age in these hospitals. Preterm neonate death accounted for 59.3% of all the death. The leading causes of death in preterm and term infants were pulmonary disease and infection, respectively. In early neonate period, pulmonary diseases (56.5%) occupied the largest proportion of preterm deaths while infection (27%) and neurologic diseases (22%) were the two main causes of term deaths. In late neonate period, infection was the leading cause of both preterm and term neonate deaths. About two-thirds of neonate death occurred after medical care withdrawal. Of the cases who might survive if receiving continuing treatment, parents' concern about the long-term outcomes was the main reason of medical care withdrawal.

CONCLUSIONSNeonate death still accounts for a high proportion of all the deaths in children under 5 years of age. Our study showed the majority of neonate death occurred in preterm infants. Cause of death varied with the age of death and gestational age. Accurate and prompt evaluation of the long-term outcomes should be carried out to guide the critical decision.
