Traditional Chinese medicine (TCM) is an important part of modern medicine. Application of modern ana-lytical techniques to identify the authenticity of TCM and evaluate its quality is an important and critical content in the process of the modernization and internationalization of TCM. This paper described the development and charac-teristics of a 1H-NMR-based metabolomics technology, and reviewed its application in the species identification, quality evaluation of Daodi Y aocai (i.e., genuine medicinal materials), processing theory and the best harvest time of TCM. Besides, based on previous work, further discussion was given on technical methods and key question of the 1H-NMR metabolomics method. This paper provided a methodological reference for the species identification and quality evaluation of TCM and other herbal medicines.

Objective:
To investigate the incidence of adverse events following immunization (AEFI) with inactivated influenza vaccine among the elderly in Huzhou City, Zhejiang Province, so as to provide insights into safety monitoring and evaluation of inactivated influenza vaccines.
Methods:
Data pertaining to surveillance on AEFI with inactivated influenza vaccines among the elderly at ages of 60 years and older in Huzhou City from 2020 to 2022 were collected from the AEFI Monitoring Information Management System of the Immunization Planning System of Chinese Disease Control and Prevention Information System, including demographics, time of AEFI occurrence, classification of AEFI and clinical syndromes, and the reported incidence and epidemiological features of AEFI with inactivated influenza vaccines were analyzed using a descriptive epidemiological method.
Results:
Totally 84 elderly cases at ages of 60 years and older were reported with AEFI with inactivated influenza vaccines in Huzhou City from 2020 to 2022, with a reported incidence rate of 9.83/105 doses, and the reported incidence rates of AEFI with trivalent and quadrivalent inactivated influenza vaccines were 9.74/105 doses and 48.71/105 doses, respectively. The reported incidence rates of general, abnormal, coincidence and psychogenic reactions were 7.96/105 doses, 1.52/105 doses, 0.23/105 doses and 0.12/105 doses, respectively, and no vaccine quality accidents or wrong vaccine administered were reported. The cases with AEFI included 52 women and 32 men, and most cases were aged from 60 to 69 years (44 cases, 52.38%). The highest incidence of AEFI was reported in Nanxun District (17.94/105 doses), and there were 79 cases (94.05%) with AEFI within 24 hours following vaccination. The clinical symptoms mainly included fever, local redness and swelling, and local induration, with reported incidence rates of 2.22/105 doses, 3.74/105 doses, and 1.99/105 doses, respectively.
Conclusions
The reported incidence of AEFI with inactivated influenza vaccines is low among the elderly at ages of 60 years and older in Huzhou City, with general reactions as predominant AEFI, and most AEFI occurs within 24 hours following vaccination.

OBJECTIVETo investigate whether acute dipterex poisoning (ADP) may cause oxidative stress and free radical damage in the bodies of acute dipterex poisoning patients (ADPPs), and to explore the mechanisms by which ADP may cause oxidative stress and free radical damage.
METHODSFifty ADPPs and fifty healthy adult volunteers (HAVs) whose ages, gender and others were matched with the ADPPs were enrolled in a randomized controlled study, in which concentrations of nitric oxide (NO), vitamin C (VC), vitamin E (VE) and beta-carotene (beta-CAR) in plasma as well as concentration of lipoperoxide (LPO), and activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPX) and acetylcholinesterase (AChE) in erythrocytes were determined by spectrophotometric analytical methods.
RESULTSCompared with the average values of experimental parameters in the HAVs group, the average values of plasma NO and erythrocyte LPO in the ADPPs group were significantly increased (P<0.0001), while those of plasma VC, VE and beta-CAR as well as erythrocyte SOD, CAT, GPX and AChE in the ADPPs group were significantly decreased (P<0.0001). Bivariate correlation analysis and partial correlation analysis suggested that when NO and LPO values were increased, and VC, VE, beta-CAR, SOD, CAT and GPX values were decreased in the ADPPs, AChE value was decreased gradually in the ADPPs (P<0.001-0.0001). Reliability analysis of experimental parameters reflecting oxidative stress and free radical damage in the ADPPs showed that the reliability coefficient (8 items) alpha=0.6909, and the standardized item alpha=0.8574.
CONCLUSIONThe findings in the present study suggest that ADP can cause oxidative stress and free radical damage, and inhibit markedly erythrocyte acetylcholinesterase activity in ADPPs.

OBJECTIVETo find out the occurrence of cesarean section (CS) and to probe the factors associated with CS.
METHODSWomen with CS as "case group" and women without CS as "control group" were chosen in a case-control study.
RESULTSAmong 14 071 childbirth women, 6 421 had CS (case group) with the occurrence rate of 45.6% and 7 650 (54.4%) had normal delivery (control group). In comparison with the control group, the CS group had following several higher rates [with significant differences between case group and control group (P < 0.01)]: well-educated (78.9% vs 69.5%), white collar jobs (38.0% vs 32.3%), urban residents (79.1% vs 70.6%), high monthly income (>/= 500 Yuan) (81.0% vs 70.6%), of older age (>/= 25 years) (73.3% vs 63.0%), heavier baby weight (> 4 000 gram) (8.3% vs 2.9%), male babies (53.9% vs 51.4%), BMI of mother (> 24) (8.8% vs 4.8%), cephalopelvic disproportion (21.1% vs 0.9%), intrauterine asphysia (20.3% vs 6.7%), abnormality of force of labor (4.2% vs 2.7%), prolonged labor (2.9% vs 1.0%) and placenta previa (1.4% vs 0.4%). Our study also indicated that the higher the educational level was, the higher the rate of CS appeared; and the older the pregnant women was, the higher the rate of CS was. In CS group, over 70% primipara were over 24 years, and over 20% primipara had cephalopelvic disproportion and over 20% had intrauterine asphysia in CS group.
CONCLUSIONSAt present, the occurrence rate of cesarean section was rather high (45.6%) in China. The high rate of CS was more likely to associate not only with abnormal physiological/medical factors (eg. cephalopelvic disproportion, intrauterine asphysia, abnormality of force of labor, and prolonged labour, etc.), but also with some demographic factors as education, occupation, income and age, etc. It is necessary to take measures to reduce the unnecessary CS in China.

BACKGROUNDRecurrence or metastasis of myxomas is not rare and can lead to malignancy. We aimed to analyze the risk factors for postoperative cardiac myxoma recurrence and to summarize its clinical characteristics, treatments and classification.
METHODSThe clinical data of 5 patients with recurrent cardiac myxoma were retrospectively analyzed and our clinical experience was summarized. Moreover, the relevant literatures were reviewed.
RESULTSAll the five cases of primary myxomas were derived from atypical positions. One patient had early distant metastasis, one had family history, and two suffered malignant recurrence. The recurrence interval was (2.30 ± 2.16) years and the recurrent tumors were all found in different chambers from those of the corresponding primary tumors. Re-operation was performed after recurrence. One patient died of heart failure after malignant recurrence, and the other 4 cases had satisfactory therapeutic outcomes after re-operations. Our experience advocated a clinical classification of "typical" and "atypical" cardiac myxoma, the typical myxomas referred to the tumors locating at the left atria, with single pedicle, rooted at or around the fossa ovalis, involving no genetic causes, and the atypical myxomas included the familial tumors, tumors stemming from multiple chambers, rooted in abnormal positions of the left atrium, with evident genetic mutation, or with malignant tendency.
CONCLUSIONSPostoperative follow-up is of vital importance for patients with myxomas characterized by multi-chamber distribution, early distant metastasis, atypical origin, and family history. Once recurs, re-operation is necessary and should be performed immediately.

OBJECTIVETo investigate whether hypertension, abnormal lipometabolism, obesity, cigarette smoking and alcohol drinking affect the intracerebral hemorrhagic volumes (IHV) in patients with spontaneous intracerebral hemorrhage (SIHP), and to explore the roles of these factors in spontaneous intracerebral hemorrhage (SIH).
METHODSFive hundred patients with acute SIH and 200 healthy adult volunteers (HAV) were enrolled in a study of independently randomized controlled design, in which the levels of systolic pressure (SP) and diastolic pressure (DP), and total cholesterol (TCH), triacylglycerols (triglycerides, TG), high density lipoprotein cholesterol (HDL-CH), low density lipoprotein cholesterol (LDL-CH) in serum as well as the level of erythrocytic membrane cholesterol (EM-CH) were measured, and the body mass index (BMI), daily cigarette smoking consumption (DCSC) and daily pure alcohol consumption (DPAC) were calculated.
RESULTSCompared with the average parameters in the HAV group, those of SP, DP, TG, LDL-CH and BMI in the SIHP group were significantly increased (P < 0.0001), while those of HDL-CH and EM-CH were significantly decreased (P < 0.0001). The linear regression and correlation analysis showed that with increased SP, DP, LDL-CH, BMI, DCSC, DPAC and aging as well as decreased HDL-CH and EM-CH, the IHV levels in SIHP were increased gradually (P < 0.0001-0.01). The linear stepwise regression analysis suggested that there existed a close correlation among the values of SP, DP, TCH, TG, HDL-CH, LDL-CH, EM-CH, BMI, DCSC, DPAC, age and IHV of the SIH patients, and that Y = -12.4583 + 0.1127SP -1.1977EM-CH + 0.9788LDL-CH + 0.2477BMI + 0.0382DCSC + 0.0248DP, P < 0.0001 approximately 0.05.
CONCLUSIONSThe findings in the present study suggest that significantly increased systolic and diastolic pressure, low density lipoprotein cholesterol, body mass index and daily cigarette smoking consumption, and significantly decreased erythrocytic membrane cholesterol may be likely the main factors affecting intracerebral hemorrhagic volumes in patients with acute spontaneous intracerebral hemorrhage.

BACKGROUNDBoth repaglinide and gliclazide are insulin secretagogues widely used in the treatment of type 2 diabetes. They stimulate insulin secretion through distinct mechanisms and may benefit patients from different aspects. The present study was to evaluate the effects of repaglinide or gliclazide on glycaemic control, insulin secretion, and lipid profiles in type 2 diabetes patients.
METHODSA total of 47 newly diagnosed type 2 diabetes patients were randomized 1:1 to receive a 4-week treatment with repaglinide or gliclazide. The standard mixed meal tolerance test was performed before and after the treatment. Plasma glucose (PG), insulin concentration, and lipid profiles were measured. The area under insulin concentration curve (AUC(ins)) and the early-phase insulin secretion index (ΔI(30)/ΔG(30)) were calculated.
RESULTSAfter the trial, fasting and postprandial PG and postprandial insulin improved significantly in both groups (P < 0.05). The maximum insulin concentration occurred earlier in the repaglinide group than that in the gliclazide group. AUC(ins) increased in both groups (P < 0.05), but no significant difference was found between groups. ΔI(30)/ΔG(30) increased in both groups (P < 0.05), especially in the repaglinide group (P < 0.05). Triglyceride and total cholesterol decreased significantly in the repaglinide group in some time points, while no significant change was observed in the gliclazide group.
CONCLUSIONSRepaglinide and gliclazide had similar effects on glycaemic control and total insulin secretion, while repaglinide had more effects on improvements in β-cell function and lipid metabolism.

OBJECTIVETo compare the responses to sepsis between C57BL/6 and BALB/c mice.
METHODSThirty C57BL/6 mice and 30 BALB/c mice were randomized into sham-operated group and sepsis group (n=15). Sepsis model was established by cecal ligation puncture (CLP) in the mice, and 6 h after the operation, 5 mice from each group were selected randomly for cytokine detection including IL-1beta, IL-2, IL-4, IL-5, IL-10, GM-CSF, IFN-gamma and TNF-alpha by Bio-plex. The other 10 mice in each group were used for survival analysis.
RESULTSThe survival rates of BALB/c and C57BL/6 mice were both 100% in one week after the sham operation, but lowered to 10% and 50% in one week after CLP, respectively. The survival rate of C57BL/6 mice was significantly lower than that of BALB/c mice (P<0.05). After CLP, C57BL/6 mice showed significantly greater IL-4, TNF-alpha and IL-10 production than the sham-operated mice, but the concentrations of the 8 cytokines in BALB/c mice after CLP showed no significant increment.
CONCLUSIONCompared with BALB/c mice, C57BL/6 strain mouse is more sensitive to sepsis.
