OBJECTIVETo explore the associations between fasting serum lipids and high-sensitivity C-reactive protein (hsCRP).

METHODSSerum triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and hsCRP were measured in residents of Chengdu, China. Subjects with potential factors which might influence lipids and hsCRP were excluded, 580 subjects [mean age (62.3 ± 6.6) years; male: 58.7%] were finally recruited by random sampling methods.

RESULTSThere was a weak positive relationship between TG and hsCRP (r = 0.108, P = 0.01) and a weak negative relationship between HDL-C and hsCRP (r = -0.197, P < 0.001), this was also true in the sub-group with BMI < 24 kg/m(2) (r = 0.236, -0.140 respectively, all P < 0.001). In subjects with BMI < 24 kg/m(2), the hsCRP concentration was significantly higher in subjects with higher TG or lower HDL-C (all P < 0.05). hsCRP increased in proportion with the degree of dyslipidemia. After adjusting for gender, age, TC, LDL-C, fasting blood glucose, systolic blood pressure, diastolic blood pressure, history of hypertension and diabetes, smoking and alcohol drinking, logistic regression analysis showed that the odds ratio for increased hsCRP was 1.970 in subjects with either increased TG or lower HDL-C (P = 0.105) and 9.098 in subjects with both higher TG or lower HDL-C levels (P = 0.031). However, the observed relationship between TG, HDL-C and hsCRP in subjects with BMI < 24 kg/m(2) could not be observed in subjects with subjects with BMI > 24 kg/m(2) despite significant more cardiovascular risk factors in these subjects.

CONCLUSIONSA weak positive correlation between TG and hsCRP as well as a weak negative correlation between HDL-C and hsCRP was evidenced in the whole cohort suggesting dyslipidemia might be related to enhanced inflammatory status. However, this relationship is not observed in subjects with BMI > 24 kg/m(2) despite existence of more cardiovascular risk factors in these subjects.

BACKGROUNDSurgery is regarded as the most effective treatment to relieve pain and reduce complications in chronic pancreatitis (CP). Two major strategies exist: duodenum-preserving pancreatic head resection (DPPHR) and pancreatoduodenectomy (PD). Many studies suggest that DPPHR offers advantages during surgery and in the short-term; however, the long-term effects have not been thoroughly investigated. We analyzed the long-term outcomes of DPPHR and PD, over follow-up times of at least 1 year, to determine the optimal surgical treatment for CP.

METHODSWe systemically reviewed all CP surgical treatment reports, and only included randomized controlled trials (RCT) comparing DPPHR and PD, excluding unqualified studies using several pre-specified criteria. When multiple publications of a single trial were found, the most comprehensive current data were selected. Characteristics of the study populations and long-term postoperative outcome parameters were collected. The quality of the studies and data was analyzed using RevMan 4.2 software.

RESULTSFive trials were qualified for meta-analysis, with 261 participants in total (114 in the DPPHR group and 147 in the PD group). There were no significant differences in the age, gender, or indications for surgery of each group. At the mean of 5.7-year (1 - 14 years) follow-up examination, DPPHR and PD resulted in equally effective pain relief, exocrine and endocrine function, and similar mortality rates (P > 0.05); however, DPPHR patients had improved global quality of life and weight gain, and reduced diarrhea and fatigue (P < 0.05).

CONCLUSIONDPPHR and PD result in equal pain relief, mortality, and pancreatic function; however, DPPHR provides superior long-term outcomes.

OBJECTIVETo evaluate the therapeutic effect of comprehensive therapeutic protocol of electroacupuncture combined with active-blood-and-dissolve-stasis herbs and rehabilitation training for cerebral infarction.

METHODSA multi-center randomized controlled trial was done, three hundred and twenty cases were divided into four groups: electroacupuncture combined with active-blood and dissolve-stasis herbs and rehabilitation training group (group A), electroacupuncture combined with rehabilitation training group (group B), herbs combined with rehabilitation training group (group C) and rehabilitation training group (group D), 80 cases in each group. The following two groups of acupoints were used alternatively in electroacupuncture treatment: the first group including Vasomotor Area, Jianyu (LI 15), Biguan (ST 31), Hegu (LI 4) and Taichong (LR 3); the second group including Motor Area, Quchi (LI 11), Yanglingquan (GB 34) and Shenshu (BL 23). 20 mL Xiangdan injection and 250 mL 5% glucose injection or 250 mL 0.9% sodium chloride injection were used by intravenous drip in herbs treatment once a day. The rehabilitation training was performed by the professional physical therapist. Each group was treated with corresponding treatment protocol. The therapeutic effect was evaluated by index of the mortality or disability rate 3 months after the onset of disease. The intention to treat analysis (ITT) was used in data.

RESULTSThe mortality or handicap rate 3 months after the onset of disease of four groups were 17.5% (14/80) in group A, 22.5% (18/80) in group B, 40. 0% (32/80) in group C, and 31.3% (25/80) in group D, respectively. The group A has a best therapeutic effect (vs group C, group D, both P<0.05), and there was no adverse event.

CONCLUSIONThe combined application of electroacupuncture, active-blood and dissolve-stasis herbs and rehabilitation training is a better treatment for cerebral infarction in clinic.

OBJECTIVEMajor histocompatibility complex class I C-related molecules A and B (MICA and MICB) are innate immune system ligands for the NKG2D receptor expressed by natural killer cells and activated CD8(+)T cells. Our previous study showed that 5-aza-2'-deoxycytidine (5-aza-dC), a DNA methyltransferase inhibitor, can induce the expression of MICB and sensitized cells to NKL-cell-mediated cytolysis. The aim of this study was to determine the expression level of MICA in HepG2 cells (an HCC cell line) and L02 cells ( a normal liver cell), and to investigate the effect of 5-aza-dC on MICA expression in HepG2 cells.

METHODSCells were treated with 5-aza-dC, caffeine and ATM-specific siRNA. The cell surface MICA protein on HepG2 cells and L02 cells was determined using flow cytometry. The mRNA level was detected using real time RT-PCR.

RESULTSMICA was undetectable on the surface of L02 cells, but was highly expressed on HepG2 cells. MICA expression was upregulated in response to 5-aza-dC treatment (P less than 0.05), and the upregulation of MICA was partially prevented by pharmacological or genetic inhibition of ataxia telangiectasia mutated (ATM) kinase (P less than 0.05).

CONCLUSIONOur data suggest that 5-aza-dC induces the expression of MICA by a DNA damage-dependent mechanism.

OBJECTIVE: To observe the changes of relative expression of myocardial various RNAs in rats died of different causes and their relationship with PMI. METHODS: The rat models were established in which the rats were sacrificed by broken neck, asphyxia, and hemorrhagic shock. Total RNAs were extracted from myocardium. The quantitative real time PCR was used to calculate threshold cycle values of RNAs including glyceraldehyde-3-phosphate dehydrogenase (GAPDH), beta-actin, inducible nitric oxide synthase (iNOS), hypoxia-inducible factor-1 (HIF-1), tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), and U6 small nuclear RNA (U6 snRNA) and to study the changes of the relative expressions of various indexes with PMI. RESULTS: U6 snRNA with stable expression level could be used as appropriate internal control. In the early PMI, the relative expression of GAPDH, HIF-1, iNOS, TNF-alpha, and IL-6 more characteristically increased in groups of asphyxia and hemorrhagic shock than in group of broken neck, but the quantity of beta-actin decreased in all groups. In the late PMI, all the relative expressions significantly declined in correlation with the degradation of RNA. CONCLUSION The characteristic changes of each RNA expression can be used as references to estimate PMI in deaths by different causes.

OBJECTIVE: To clone the full-length gene encoding succinate dehydrogenase iron-sulfur protein of Schistosoma japonicum (SjSDISP) Chinese strain and express it in Escherichia coli. METHODS: According to the published incomplete EST (BU804141) of SjSDISP and the sequence of multiclone sites of lambda gt11 vector, 2 pairs of primers were designed and synthesized. Then the 3' and 5'ends of the EST of the SjSDISP from adult Schistosoma japonicum cDNA library were amplified by anchored PCR. After sequencing, a full-length cDNA sequence of the SjSDISP was obtained, and then it was cloned into prokaryotic expression vector pGEX-4T-1. Identified by agarosed gel electrophoresis, endonucleases digestion and PCR, the resultant recombinant plasmid was used for the expression under the temperature-dependent condition and Western blot analysis. RESULTS: A 1,071 bp sequence was obtained. Sequence analysis showed that the fragment contained a complete open reading frame (ORF), encoding 278 amino acid residues. This target fragment was cloned into the prokaryotic expression vector pGEX-4T-1, and expressed in Escherichia coli. SDS-PAGE revealed that the molecular weight of the expressed fusion recombinant product was 56 kD. Western blot showed that the recombinant protein was recognized by polyclonal rabbit antiserum immunized with Schistosoma japonicum adult worm antigen. CONCLUSION Cloning of the full-length gene encoding SjSDISP and its bacterial expression were successfully done.

Blunt traumatic thoracic aortic injury (BTAI) is an extremely serious medical condition with a high rate of associated mortality. Recent advances in techniques such as thoracic endovascular repair offer new opportunities to manage the critical BTAI patients in an efficacious yet less invasive manner. A 65 year-old-male suffered from multiple injuries after a fall, including BTAI in the aortic arch, which resulted in dissection of the descending thoracic-abdominal aorta and iliac artery, development of an intimal flap in the left common carotid artery, and dissection of the left subclavian artery. Based on the imaging information of this patient and our clinical experience, the combined treatment of fenestrated thoracic endovascular repair and a chimney technique was immediately planned to fully repair these dissections and moreover prevent further dissection of the branching vessels, additionally to ensure sufficient blood flow in the left subclavian artery and left common carotid artery. The intervention yielded satisfactory early outcomes. Follow-up assessment at six months reported no symptoms or complications associated with the stent-graft. Computed tomography angiography further confirmed adequate stent-graft coverage of the aortic injury.

Objective To study the correlation between the abdominal wall subcutaneous fat thickness and heart weight, so as to provide reference for prediction methods of normal range of heart weight that is suitable for autopsy in China. Methods The forensic pathology autopsy cases accepted by Center for Medicolegal Expertise of Sun Yat-sen University from 1998 to 2017 were collected. Then the exclusion criteria were determined, and according to them the total case group was selected, and the 6 disease groups and the normal group were further selected from the total case group. The rank sum test was used to compare the heart weight of the normal group and the disease groups to determine the influence of diseases on heart weight. Then the Spearman rank correlation analysis of abdominal wall subcutaneous fat thickness and heart weight in different genders and different ages in the total case group and the normal group was conducted to get the correlation coefficient （r_s）. Results In the total case group, correlation between abdominal wall subcutaneous fat thickness and heart weight was shown in males of all ages （P<0.05）; while in females, the correlation had no statistical significance （P>0.05） in 15-<20 age and 50-<60 age, but was statistically significant （P<0.05） in other age groups. For the males in the normal group, r_s was respectively 0.411, 0.541 and 0.683 in the 15-<40 age, the 40-<60 age, and the ≥60 age. For the females, r_s was respectively 0.249 and 0.317 in the 15-<40 age and the 40-<60 age. The correlation in the ≥60 age had no statistical significance（P>0.05）. Conclusion In the general population and the normal population, abdominal wall subcutaneous fat thickness is correlated with the heart weight of males. It is of significance to include the abdominal wall subcutaneous fat thickness in the prediction of normal range of heart weight for males in China.

Objective: To investigate the incidence and risk factors of systemic allergic reactions induced by subcutaneous immunotherapy (SCIT) in patients undergoing SCIT injections in Peking Union Medical College Hospital (PUMCH). Methods: This is a single center retrospective cohort study. Using the outpatient information system of PUMCH, the demographic information and injection-related reaction data of patients undergoing SCIT injection in Allergy Department of PUMCH from December 2018 to December 2022 were retrospectively analyzed to count the incidence and risk factors of systemic allergic reactions caused by SCIT. Mann-Whitney nonparametric test or chi-square test was used for single-factor analysis, and multiple logistic regression was used for multiple-factor analysis. Results: A total of 2 897 patients received 18 070 SCIT injections in Allergy Department during the four years, and 40 systemic allergic reactions occurred, with the overall incidence rate of 0.22%. The incidence of systemic allergic reaction was 0.37% when using imported dust mite preparation and 0.15% when using domestic multi-component allergen preparation. The risk factors significantly related with SCIT-induced systemic allergic reactions in patients using imported dust mite preparation were age less than 18 years old (OR=3.186,95%CI: 1.255-8.085), highest injection concentration (OR value could not be calculated because all patients with systemic reactions were injected with highest concentration), and large local reaction in previous injection (OR=22.264,95%CI: 8.205-60.411). The risk factors for SCIT-induced systemic allergic reactions in patients using domestic allergen preparation were 5 or more types of allergens (OR=3.455,95%CI: 1.147-10.402), highest injection concentration (OR=3.794,95%CI: 1.226-11.740) and large local reaction in previous injection (OR=63.577,95%CI: 22.248-181.683). However, SCIT injection in pollen allergic patients during the pollen season did not show a correlation with systemic allergic reaction. Conclusion: The incidence of SCIT-induced systemic allergic reactions was low in the Chinese patient population of this study. Patients with one or more risk factors, such as multiple allergen injection, highest injection concentration, large local reaction in previous injection, should be given high attention and vigilance against systemic allergic reactions.
