Objective:To observe the clinical efficacy of body acupuncture combined with FANG's scalp acupuncture in treating limb dysfunction in the remission stage of stroke and explore the mechanism. Methods:Sixty patients in the remission stage of stroke with limb dysfunction were divided into a control group and a treatment group using the random number table method,with 30 cases in each group.The control group was treated with ordinary acupuncture based on the conventional rehabilitation treatment,and the treatment group was additionally offered FANG's scalp acupuncture.The interventions were conducted once daily with 10 sessions as 1 course.The Fugl-Meyer assessment(FMA)and Barthel index(BI)scores and serum malondialdehyde(MDA)and superoxide dismutase(SOD)levels were compared after 2 treatment courses,and the clinical efficacy was evaluated. Results:After treatment,the FMA and BI scores increased in both groups(P<0.05)and were higher in the treatment group than in the control group(P<0.05).Both groups showed a decreased MDA level and an increased SOD level after the intervention,all showing statistical significance(P<0.05);there were significant differences between the two groups(P<0.05). Conclusion:Based on the conventional rehabilitation treatment,ordinary acupuncture used alone or in combination with FANG's scalp acupuncture can lower the oxidative stress level and improve limb function in treating limb dysfunction in the remission stage of stroke;body acupuncture plus FANG's scalp acupuncture can produce better results.

Aim To investigate the mechanism and search for potential biomarkers of ovalbumin ( OVA ) -induced asthma in mice base on lipidomics. Methods A BALB/c mouse model of asthma was prepared by OVA. TNF-α, IL-4, IL-10, IFN-γ levels in BALF and IgE level in serum were measured by ELISA. The inflammatory changes in mouse lung tissue were observed using HE staining. Lipid mediators ( LMs) in lung tissue and serum were quantified with UPLC-MS/ MS strategy. Results IgE level in serum and TNF-α, IFN-γ levels in BALF were higher (P <0.05) of asthmatic mice.Typical inflammatory manifestations were seen in lung tissue of asthmatic mice. A total of 57 lipid mediators were quantified with UPLC-MRM. LMs metabolic profiles differed significantly in serum and lung tissue between asthmatic and normal mice, 17 significantly different LMs were found in lung tissue and 6 LMs were found in serum, and the differential metabolites were produced through the cyclooxygenase (COX), lipoxygenase (LOX) and cytochrome P450 oxidase (P450) metabolic pathways. Conclusions OVA-induced allergic asthma can cause disorder of lip-id mediators, LMs and cytokines are involved in the occurrence and development of asthma. The differential LMs have potential research value as biomarkers for the development of allergic asthma.

OBJECTIVES: To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China. METHODS: A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups. RESULTS: Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05). CONCLUSIONS There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

Objective: To analyze the clinical epidemiological characteristics including composition of pathogens , clinical characteristics, and disease prognosis acute bacterial meningitis (ABM) in Chinese children. Methods: A retrospective analysis was performed on the clinical and laboratory data of 1 610 children <15 years of age with ABM in 33 tertiary hospitals in China from January 2019 to December 2020. Patients were divided into different groups according to age,<28 days group, 28 days to <3 months group, 3 months to <1 year group, 1-<5 years of age group, 5-<15 years of age group; etiology confirmed group and clinically diagnosed group according to etiology diagnosis. Non-numeric variables were analyzed with the Chi-square test or Fisher's exact test, while non-normal distrituction numeric variables were compared with nonparametric test. Results: Among 1 610 children with ABM, 955 were male and 650 were female (5 cases were not provided with gender information), and the age of onset was 1.5 (0.5, 5.5) months. There were 588 cases age from <28 days, 462 cases age from 28 days to <3 months, 302 cases age from 3 months to <1 year of age group, 156 cases in the 1-<5 years of age and 101 cases in the 5-<15 years of age. The detection rates were 38.8% (95/245) and 31.5% (70/222) of Escherichia coli and 27.8% (68/245) and 35.1% (78/222) of Streptococcus agalactiae in infants younger than 28 days of age and 28 days to 3 months of age; the detection rates of Streptococcus pneumonia, Escherichia coli, and Streptococcus agalactiae were 34.3% (61/178), 14.0% (25/178) and 13.5% (24/178) in the 3 months of age to <1 year of age group; the dominant pathogens were Streptococcus pneumoniae and the detection rate were 67.9% (74/109) and 44.4% (16/36) in the 1-<5 years of age and 5-<15 years of age . There were 9.7% (19/195) strains of Escherichia coli producing ultra-broad-spectrum β-lactamases. The positive rates of cerebrospinal fluid (CSF) culture and blood culture were 32.2% (515/1 598) and 25.0% (400/1 598), while 38.2% (126/330)and 25.3% (21/83) in CSF metagenomics next generation sequencing and Streptococcus pneumoniae antigen detection. There were 4.3% (32/790) cases of which CSF white blood cell counts were normal in etiology confirmed group. Among 1 610 children with ABM, main intracranial imaging complications were subdural effusion and (or) empyema in 349 cases (21.7%), hydrocephalus in 233 cases (14.5%), brain abscess in 178 cases (11.1%), and other cerebrovascular diseases, including encephalomalacia, cerebral infarction, and encephalatrophy, in 174 cases (10.8%). Among the 166 cases (10.3%) with unfavorable outcome, 32 cases (2.0%) died among whom 24 cases died before 1 year of age, and 37 cases (2.3%) had recurrence among whom 25 cases had recurrence within 3 weeks. The incidences of subdural effusion and (or) empyema, brain abscess and ependymitis in the etiology confirmed group were significantly higher than those in the clinically diagnosed group (26.2% (207/790) vs. 17.3% (142/820), 13.0% (103/790) vs. 9.1% (75/820), 4.6% (36/790) vs. 2.7% (22/820), χ²=18.71, 6.20, 4.07, all P<0.05), but there was no significant difference in the unfavorable outcomes, mortility, and recurrence between these 2 groups (all P>0.05). Conclusions: The onset age of ABM in children is usually within 1 year of age, especially <3 months. The common pathogens in infants <3 months of age are Escherichia coli and Streptococcus agalactiae, and the dominant pathogen in infant ≥3 months is Streptococcus pneumoniae. Subdural effusion and (or) empyema and hydrocephalus are common complications. ABM should not be excluded even if CSF white blood cell counts is within normal range. Standardized bacteriological examination should be paid more attention to increase the pathogenic detection rate. Non-culture CSF detection methods may facilitate the pathogenic diagnosis.

Objective: To evaluate the efficiency of internal carotid artery (ICA) embolization technology in endoscopic salvage surgery for recurrent nasopharyngeal carcinoma (rNPC) invading the ICA. Methods: From January 2016 to March 2021, 83 patients with rNPC who invaded the ICA and underwent endoscopic extended nasopharyngectomy were retrospectively collected from the Eye & ENT Hospital in Fudan University, including 60 males and 23 females. The age of the patients ranged from 27 to 77 years. The standard of ICA invasion was that the distance from the lesion to the ICA on enhanced MRI was ≤ 1.8 mm. The clinical characteristics, ICA management strategy and survival prognosis of patients were analyzed, and the effectiveness of ICA embolization was evaluated. Kaplan-Meier method was used to calculate the survival rate and Log-rank test was used to compare the difference. Results: In 83 patients with rNPC, there were 13 patients with rT2, 38 patients with rT3, 32 patients with rT4, and 16 patients had lymph node metastasis. A total of 37 patients (44.6%) underwent ICA coil embolization before surgery, of which 2 cases underwent external carotid-middle cerebral artery artery bypass grafting and ICA embolization due to positive balloon occlusion test (BOT). Patients with positive surgical margin accounted for 24.1% (20/83). Among them, patients with rT4 and patients without ICA embolization had a higher positive rate of surgical margin (P value was 0.001, 0.043, respectively). The 3-year overall survival (OS) and progression free survival (PFS) rate of all patients was 46.5% and 26.7%, respectively. In addition, the 3-year OS and PFS of patients with ICA embolization was significantly higher than those without ICA embolization, respectively (69.1% vs 27.8%, P=0.003; 33.9% vs 18.9%, P=0.018). Only 2 patients (2/37, 5.4%) had cerebral infarction complications after coil embolization of the affected ICA due to negative BOT. Conclusion: Preoperative ICA embolization can be used to treat patients with rNPC invading the ICA, improve the total removal rate and survival rate of patients, which is an effective salvage treatment.

OBJECTIVE: To observe the effect of electroacupuncture (EA) combined with lifestyle control on hepatic fat status, hepatic enzymology, glycolipid metabolism and anthropological parameters in patients with obese nonalcoholic fatty liver disease(NAFLD). METHODS: A total of 90 patients with obese NAFLD were randomized into an observation group (45 cases, 4 cases dropped off) and a control group (45 cases, 1 case dropped off). Lifestyle control was implemented in the control group. On the basis of the treatment in the control group, acupuncture was applied at Zhongwan (CV 12), Quchi (LI 11), Shuifen (CV 9), Huaroumen (ST 24), Daheng (SP 15), Guanyuan (CV 4), Qihai (CV 6), etc. EA was provided at Huaroumen (ST 24) and Daheng (SP 15) with dilatational wave, 2 Hz/100 Hz in frequency, 30 min each time, once every other day, 3 times a week. The treatment for 12 weeks was required in both of the two groups. Hepatic fat status [controlled attenuation parameter (CAP) and liver stiffness measurement (LSM)], hepatic enzymology [alanine aminotransferase (ALT), aspartate aminotransferase (AST) and γ-glutamyl transferase (GGT)], glycolipid metabolism and insulin sensitivity [fasting plasma glucose (FPG), fasting serum lisulin (FINS), homeostasis model assessment of insulin resistance (HOMA-IR), total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C)] and anthropological parameters [body weight (BW), body mass index (BMI), fat percentage (FP), waist circumference (WC), hip circumference (HC) and waist-to-hip ratio (WHR)] in the two groups were observed before and after treatment. RESULTS: ①Compared before treatment, hepatic CAP, LSM, serum ALT, AST and GGT after treatment were obviously reduced in the two groups (<0.05, <0.01). After treatment, CAP and ALT in the observation group were lower than the control group (<0.05). ②Compared before treatment, FINS, HOMA-IR, LDL-C, TC and TG after treatment were obviously reduced in the two groups (<0.05, <0.01),while the levels of HDL-C were increased (<0.05). Compared before treatment, FPG after treatment in the observation group was reduced (<0.05). Compared with the control group, FINS, HOMA-IR, TC and TG in the observation group were lower than those in the control group after treatment (<0.05). ③Compared before treatment, BW BMI, FP, WC, HC, WHR after treatment were obviously reduced in the two groups (<0.01). After treatment, WC and WHR in the observation group were lower than the control group (<0.05). CONCLUSION Electroacupuncture combined with lifestyle control can effectively treat obese nonalcoholic fatty liver disease, and present better therapeutic effect on hepatic fat status, glycolipid metabolism, insulin resistance, WC and WHR.

BACKGROUNDInterferon-gamma release assay (IGRA) has been used in latent tuberculosis (TB) infection and TB diagnosis, but the results from different high TB-endemic countries are different. The aim of this study was to investigate the value of IGRA in the diagnosis of active pulmonary TB (PTB) in China.

METHODSWe conducted a large-scale retrospective multicenter investigation to further evaluate the role of IGRA in the diagnosis of active PTB in high TB-epidemic populations and the factors affecting the performance of the assay. All patients who underwent valid T-SPOT.TB assays from December 2012 to November 2015 in six large-scale specialized TB hospitals in China and met the study criteria were retrospectively evaluated. Patients were divided into three groups: Group 1, sputum culture-positive PTB patients, confirmed by positive Mycobacterium tuberculosis sputum culture; Group 2, sputum culture-negative PTB patients; and Group 3, non-TB respiratory diseases. The medical records of all patients were collected. Chi-square tests and Fisher's exact test were used to compare categorical data. Multivariable logistic analyses were performed to evaluate the relationship between the results of T-SPOT in TB patients and other factors.

RESULTSA total of 3082 patients for whom complete information was available were included in the investigation, including 905 sputum culture-positive PTB cases, 914 sputum culture-negative PTB cases, and 1263 non-TB respiratory disease cases. The positive rate of T-SPOT.TB was 93.3% in the culture-positive PTB group and 86.1% in the culture-negative PTB group. In the non-PTB group, the positive rate of T-SPOT.TB was 43.6%. The positive rate of T-SPOT.TB in the culture-positive PTB group was significantly higher than that in the culture-negative PTB group (χ2 = 25.118, P < 0.01), which in turn was significantly higher than that in the non-TB group (χ2 = 566.116, P < 0.01). The overall results were as follows: sensitivity, 89.7%; specificity, 56.37%; positive predictive value, 74.75%; negative predictive value, 79.11%; and accuracy, 76.02%.

CONCLUSIONSHigh false-positive rates of T-SPOT.TB assays in the non-TB group limit the usefulness as a single test to diagnose active TB in China. We highly recommend that IGRAs not be used for the diagnosis of active TB in high-burden TB settings.

To investigate the inhibitory effect of isobutyrylshikonin on the growth of human colon carcinoma cells and its effect on the PI3K/Akt/m-TOR pathway. MTT assay was used to detect the inhibitory effect of different concentrations (0, 6.25, 12.5, 25, 50, 100 mg·L⁻¹) of isobutyrylshikonin on the proliferation of human colon carcinoma cell HT29 at 24, 48 h. CCK-8 method was used to detect the inhibitory effect of isobutyrylshikonin on HT29, HCT116, DLD-1 and Caco-2 at 48 h. AnnexinV/propidium iodide staining was applied in detecting the apoptoticrate of HT29 cells treated with different concentrations of isobutyrylshikonin at 24 h and 48 h. Cycletest plus DNA was employed to analyze HT29 apoptosis and cell cycle after 48 h treatment with isobutyrylshikonin at different concentrations. Western blot and RT-PCR assay were used to examine the protein and mRNA expressions of PI3K, p-PI3K, Akt, p-Akt and m-TOR. The results showed that isobutyrylshikonin inhibited the proliferation of different human colon carcinoma cells, and the inhibition rate was in a dose-dependent manner. Isobutyrylshikonin induced apoptosis mainly in the early stage and blocked cells in the G₀/G₁ or G₂/M phase. Isobutyrylshikonin reduced the protein expressions of PI3K, p-PI3K, Akt, p-Akt, m-TOR and the mRNA expressions of PI3K, Akt, m-TOR in a dose-dependent manner. Isobutyrylshikonin can significantly inhibit the proliferation, induce the early apoptosis and change the cycle distribution in colon carcinoma cells.This biological effect may be correlated with the inhibition of PI3K/AKT/m-TOR pathway.
