OBJECTIVETo improve the prognosis of patients with abdominal trauma.
METHODSBetween January 1993 and December 2005, 415 patients were enrolled in this research. The patients consisted of 347 males and 68 females with mean age of 36 years (ranging from 3-82 years). All abdominal traumas consisted of closed traumas (360 cases, 86.7%) and open traumas (55 cases, 13.3%).
RESULTSA total of 407 cases (98.1%) were fully recovered from trauma and the other 8 cases (1.9%) died of multiple injuries. The mean injury severity score (ISS) of all patients was 22 while the mean ISS of the patients who died in hospital was 42. Postoperative complications were seen in 9 patients such as infection of incisional wounds (6 cases), pancreatic fistula (2 cases) and intestinal fistula (1 case). All these postoperative complications were cured by the conservative treatment.
CONCLUSIONCareful case history inquisition and physical examination are the basic methods to diagnose abdominal trauma. Focused abdominal ultrasonography is always the initial imaging examination because it is non-invasive and can be performed repeatedly with high accuracy. The doctors should consider the severity of local injuries and the general status of patients during the assessment of abdominal trauma. The principle of treatment is to save lives at first, then to cure the injuries. Unnecessary laparotomy should be avoided to reduce additional surgical trauma.

Objective:To observe the possible toxicity of long-term intravenous injection of Tanreqing injection in Beagle dogs, so as to provide experimental data for its clinical safe medication. Method:A total of 32 Beagle dogs (16 males and 16 females) were randomly divided into the low- (2.5 mL·kg-1), medium- (5.0 mL·kg-1), and high-dose (10.0 mL·kg-1) Tanreqing injection groups and control group according to their body mass indices, with eight dogs in each group. In the waking state, the dogs were treated with intravenous injection of corresponding drugs into the medial cephalic vein of forelimb for 13 weeks, followed by four-week drug withdrawal. After the observation of general condition, body mass, and food consumption, the Beagle dogs were subjected to electrocardiography, ophthalmoscopy, hematological examination, serum biochemistry, and blood coagulation test in the middle of medication (week 6), at the end of medication (week 13), and during recovery (week 17). Then the gross anatomy was conducted for calculating the major organ coefficients and observing the histopathological changes. Result:No obvious toxic reaction was found in each group, but the decreased fibrinogen and increased Kupffer's cells phagocytizing yellow-brown pigment in hepatic sinusoids were observed in the high-dose Tanreqing injection group following three months of medication. Reduction of fibrinogen was not observed in recovery period, but Kupffer's cells that phagocytized yellow-brown pigment still existed. Conclusion:The intravenous injection of Tanreqing injection at 2.50 mL·kg-1 (low dose), 5.00 mL·kg-1 (medium dose) or 10.00 mL·kg-1 (high dose) for three months in Beagle dogs resulted in no obvious toxic reaction. However, it is still suggested to test the liver function and blood coagulation after long-term administration of high-dose Tanreqing injection.

Objective: To observe the effect of modified Erchentang on the expression of interleukin-19 (IL-19), interleukin-20 (IL-20)and their receptor IL-20R1, IL-20R2 in bronchioles of rats with chronic obstructive pulmonary disease (COPD), and to explore the molecular mechanism of modified Erchentang on anti-inflammatory of COPD. Method: The model of rat with COPD was established by cigarette smoke combined with lipopolysaccharide (LPS). The experimental rats were randomly divided into 6 groups:normal group, model group, modified Erchentang high, medium and low dose group, and Jizhitangjiang group. Normal group and model group fed with normal saline 4 mL · d-1, modified Erchentang high, middle, low dosage group(20,10,5 g · kg-1 · d-1).The dosage of Jizhitangjiang group was 12 g · kg-1 · d-1, all groups were given intragastric administration for 14 days, twice a day. To observe the general situation of rats.To evaluate the pulmonary function of rats. To detect the contents of IL-10, IL-19 and IL-20 in serum by enzyme-linked immunosorbent assay (ELISA).To observe the pathological changes of bronchiole tissue by light microscopy.To detect the expression of IL-20R1 and IL-20R2 in bronchiole tissue by immunohistochemistry. Result: Compared with normal group, peak expiratory flow(PEF), forced expiratory volume in one second(FEV1), forced vital capacity (FVC), and FEV1/FVC in model group were significantly increased (P<0.05), the content of IL-19, IL-20 in serum significantly increased(P<0.05), the content of IL-10 in serum was significantly decreased (P<0.05), the expression of IL-20R1 and in bronchioles tissue significantly increased (P<0.05). Compared with model group, the PEF, FEV1, FVC, FEV1/FVC of Jizhitangjiang group, modified Erchentang high, medium and low dosage group were significantly increased(P<0.05).The content of IL-19, IL-20 in serum significantly decreased(P<0.05), the content of IL-10 in serum was significantly increased (P<0.05), the expression of IL-20R1 and IL-20R2 in bronchioles tissue was significantly decreased (P<0.05). Conclusion: Modified Erchentang can improve the lung function and protect the tissue structure of bronchioles in COPD rats, which may be related to the inhibition of the expression of IL-19, IL-20 and their receptor IL-20R1, IL-20R2 in bronchioles of rats with modified Erchentang.

OBJECTIVE:
To evaluate the associations of lipid indicators and mortality in Beijing Elderly Comprehensive Health Cohort Study.
METHODS:
A prospective cohort was conducted based on Beijing Elderly Comprehensive Health Cohort Study with 4499 community older adults. After the baseline survey, the last follow-up was March 31, 2021 with an average 8.13 years of follow-up. Cox proportional hazard model was used to estimate the hazard ratios (HR) with 95% CI for cardiovascular disease (CVD) death and all-cause death in associations with baseline lipid indicators.
RESULTS:
A total of 4499 participants were recruited, and the mean levels of uric acid, body mass index, systolic blood pressure, diastolic blood pressure, fasting plasma glucose, total cholesterol (TC), triglyceride, and low-density lipoprotein cholesterol (LDL-C) showed an upward trend with the increasing remnant cholesterol (RC) quarters (Ptrend < 0.05), while the downward trend was found in high-density lipoprotein cholesterol (HDL-C). During the total 36,596 person-years follow-up, the CVD mortality and all-cause mortality during an average 8.13 years of follow-up was 3.87% (95% CI: 3.30%-4.43%) and 14.83% (95% CI: 13.79%-15.86%) with 174 CVD death participants and 667 all-cause death participants. After adjusting for confounders, the higher level of TC (HR = 0.854, 95% CI: 0.730-0.997), LDL-C (HR = 0.817, 95% CI: 0.680-0.982) and HDL-C (HR = 0.443, 95% CI: 0.271-0.724) were associated with lower risk of CVD death, and the higher level of HDL-C (HR = 0.637, 95% CI: 0.501-0.810) were associated with lower risk of all-cause death. The higher level of RC (HR = 1.276, 95% CI: 1.010-1.613) increase the risk of CVD death. Compared with the normal lipid group, TC ≥ 6.20 mmol/L group and LDL-C ≥ 4.10 mmol/L group were no longer associated with lower risk of CVD death, while RC ≥ 0.80 mmol/L group was still associated with higher risk of CVD death. In normal lipid group, the higher levels of TC, LDL-C and HDL-C were related with lower CVD death.
CONCLUSIONS
In community older adults, higher levels of TC and HDL-C were associated with lower CVD mortality in normal lipid reference range. Higher RC was associated with higher CVD mortality, which may be a better lipid indicator for estimating the CVD death risk in older adults.
