This study aimed to investigate the effect of Wenyang Zhenshuai Granules(WYZSG) on autophagy and apoptosis of myocardial cells in rats with sepsis via regulating the expression of microRNA-132-3p(miR-132-3p)/uncoupling protein 2(UCP2). Sixty SD rats were randomly divided into modeling group(n=50) and sham operation group(n=10). The sepsis rat model was constructed by cecal ligation and perforation in the modeling group. The successfully modeled rats were randomly divided into WYZSG low-, medium-and high-dose groups, model group and positive control group. Rats in the sham operation group underwent opening and cecum division but without perforation and ligation. Hematoxylin-eosin(HE) staining was used to observe the pathological changes of rat myocardial tissue. Myocardial cell apoptosis was detected by TdT-mediated dUTP nick end labeling(TUNEL) assay. Real-time quantitative polymerase chain reaction(RT-qPCR) was performed to detect the expression of miR-132-3p and the mRNA expressions of UCP2, microtubule-associated protein light chain 3(LC3-Ⅱ/LC3-Ⅰ), Beclin-1 and caspase-3 in rat myocardial tissue. The protein expressions of UCP2, LC3-Ⅱ/LC3-Ⅰ, Beclin-1 and caspase-3 in myocardial tissue were detected by Western blot. Dual luciferase reporter assay was used to verify the regulatory relationship between miR-132-3p and UCP2. The myocardial fibers of sepsis model rats were disordered, and there were obvious inflammatory cell infiltration as well as myocardial cell edema and necrosis. With the increase of the WYZSG dose, the histopathological changes of myocardium were improved to varying degrees. Compared with the conditions in the sham operation group, the survival rate and left ventricular ejection fraction(LVEF) of rats in the model group, positive control group and WYZSG low-, medium-and high-dose groups were decreased, and the myocardial injury score and apoptosis rate were increased. Compared with the model group, the positive control group and WYZSG low-, medium-and high-dose groups had elevated survival rate and LVEF, and lowered myocardial injury score and apoptosis rate. The expression of miR-132-3p and the mRNA and protein expressions of UCP2 in myocardial tissue in the model group, positive control group and WYZSG low-, medium-and high-dose groups were lower, while the mRNA and protein expressions of LC3-Ⅱ/LC3-Ⅰ, Beclin-1 and caspase-3 were higher than those in the sham operation group. Compared with model group, the positive control group and the WYZSG low-, medium-and high-dose groups had an up-regulation in the expression of miR-132-3p and the mRNA and protein expressions of UCP2, while a down-regulation in the mRNA and protein expressions of LC3-Ⅱ/LC3-Ⅰ, Beclin-1 and caspase-3. WYZSG inhibited excessive autophagy and apoptosis of myocardial cells in septic rats and improved myocardial injury, possibly by regulating the expression of miR-132-3p/UCP2.

In this study, the evidence mapping methodology was used to systematically retrieve and sort out the clinical research evidence of Chinese patent medicines in the treatment of tension-type headache(TTH), and to understand the distribution of evidence in this field and the basis and quality of evidence. Chinese and English articles on the 28 Chinese patent medicines for TTH, which were recorded in National Essential Medicines List(2018), Medicine Catalogue for National Basic Medical Insurance, Work Injury Insurance, and Maternity Insurance(2020), and Chinese Pharmacopoeia(2020), were retrieved from China National Knowledge Infrastructure(CNKI), Wanfang, VIP, China Biology Medicine disc(CBMdisc), PubMed, EMbase, and Cochrane Library from the establishment to June 2021, followed by descriptive analysis. Then, tables and bubble charts were plotted to analyze the distribution characteristics of evidence. A total of 129 eligible articles were yielded: 126 randomized/non-randomized controlled trials, and 3 systematic reviews. The functions, indications, and composition of the 28 medicines, as well as the proportion of related articles, publication trends, intervention measures, and outcome indicators were compared and analyzed. The results showed that the 28 Chinese patent medicines, composed of 128 Chinese medicinals, can be classified into six categories in terms of function: reinforcing healthy Qi, tranquilizing mind, dispelling stasis, regulating Qi, treating wind, and resuscitating. There are ongoing efforts to study the treatment of TTH with Chinese patent medicine in China, despite of little evidence. The clinical positioning of Chinese patent medicine for TTH is not clear, and clinical research fails to highlight the advantages of Chinese medicine. In addition, the outcome indicators have not been standardized and unified, and there is a lack of evidence on the long-term efficacy of Chinese patent medicine for TTH. This study is the first exploratory application of evidence maps to compare the characteristics and clinical research progress of 28 Chinese patent medicines for TTH, which can provide a reference for research on the optimization of Chinese medicine strategies for TTH.

OBJECTIVE: To investigate the clinical features and outcome of neonatal acute respiratory distress syndrome (ARDS) in southwest Hubei, China. METHODS: According to the Montreux definition of neonatal ARDS, a retrospective clinical epidemiological investigation was performed on the medical data of neonates with ARDS who were admitted to Department of Neonatology/Pediatrics in 17 level 2 or level 3 hospitals in southwest Hubei from January to December, 2017. RESULTS: A total of 7 150 neonates were admitted to the 17 hospitals in southwest Hubei during 2017 and 66 (0.92%) were diagnosed with ARDS. Among the 66 neonates with ARDS, 23 (35%) had mild ARDS, 28 (42%) had moderate ARDS, and 15 (23%) had severe ARDS. The main primary diseases for neonatal ARDS were perinatal asphyxia in 23 neonates (35%), pneumonia in 18 neonates (27%), sepsis in 12 neonates (18%), and meconium aspiration syndrome in 10 neonates (15%). Among the 66 neonates with ARDS, 10 neonates (15%) were born to the mothers with an age of ≥35 years, 30 neonates (45%) suffered from intrauterine distress, 32 neonates (49%) had a 1-minute Apgar score of 0 to 7 points, 24 neonates (36%) had abnormal fetal heart monitoring results, and 21 neonates (32%) experienced meconium staining of amniotic fluid. Intraventricular hemorrhage was the most common comorbidity (12 neonates), followed by neonatal shock (9 neonates) and patent ductus arteriosus (8 neonates). All 66 neonates with ARDS were treated with mechanical ventilation in addition to the treatment for primary diseases. Among the 66 neonates with ARDS, 10 died, with a mortality rate of 15% (10/66), and 56 neonates were improved or cured, with a survival rate of 85% (56/66). CONCLUSIONS Neonatal ARDS in southwest Hubei is mostly mild or moderate. Perinatal asphyxia and infection may be the main causes of neonatal ARDS in this area. Intraventricular hemorrhage is the most common comorbidity. Neonates with ARDS tend to have a high survival rate after multimodality treatment.

OBJECTIVETo study the relationship between nasal carriage and Staphylococcus aureus (S. aureus) infection in hospitalized children.

METHODSFifty-six hospitalized children infected with S. aureus were recruited in this study. Nasal swabs were collected and cultured, and the nasal carriage rate of S. aureus was examined. PVL virulence gene and mecA resistance gene were both detected in clinical strains and nasal carriage strains by PCR.

RESULTSTwenty-two (39%) of the 56 children had nasal carriage of S. aureus, and most of them (18 cases) were younger than one year. Among these 22 children, 11 (50%) had previous hospitalization over the past year. In the infected strains, the rate of methicillin-resistant S. aureus (MRSA) was 29% (16/56), while it was 32% (7/22) in carriage strains. The mecA positive results in clinical strains were consistent with the results in nasal carriage strains. Among 5 PVL-positive nasal carriage strains, 4 (90%) could be matched with their clinical strains, all of which were MRSA.

CONCLUSIONSNasal carriage is a potential risk factor for S. aureus infection. Nosocomial transmission may lead to nasal carriage, which can cause S. aureus infection. The isolation rate of MRSA is high in hospitalized children infected with S. aureus, which implies that more attention is needed for this situation. The isolates from noses may be clonally identical to the isolates from clinical secretions, and the homology between them needs to be confirmed by multi-locus sequence typing.

OBJECTIVETo compare the clinical efficacy in the treatment of post-stroke shoulder-hand syndrome between floating-needle therapy and conventional acupuncture on the basis of rehabilitation training.

METHODSOne hundred cases of post-stroke shoulder-hand syndrome were randomized into a floating-needle group and an acupuncture group, 50 cases in each one. The passive and positive rehabilitation training was adopted in the two groups. Additionally, in the floating-needle group, the floating-needle therapy was used. The needle was inserted at the site 5 to 10 cm away from myofasical trigger point (MTrP), manipulated and scattered subcutaneously, for 2 min continuously. In the acupuncture group, the conventional acupuncture was applied at Jianqian (EX-UE), Jianyu (LI 15), Jianliao (TE 14), etc. The treatment was given once every two days, 3 times a week, and 14 days of treatment were required. The shoulder hand syndrome scale (SHSS), the short form McGill pain scale (SF-MPQ) and the modified Fugl-Meyer motor function scale (FMA) were used to evaluate the damage severity, pain and motor function of the upper limbs before and after treatment in the two groups. The clinical efficacy was compared between the two groups.

RESULTSSHSS score, SF-MPQ score and FMA score were improved significantly after treatment in the two groups (all P < 0.01), and the improvements in the floating-needle group were superior to those in the acupuncture group (all P < 0.05). The total effective rate was 94.0% (47/50) in the floating-needle group, which was better than 90.0% (45/50) in the acupuncture group (P < 0.05).

CONCLUSIONThe floating-needle therapy combined with rehabilitation training achieves a satisfactory efficacy on post-stroke shoulder-hand syndrome, which is better than the combined therapy of conventional acupuncture and rehabilitation training.

The clinical therapeutic effect of acupoint catgut-embedding for simple obesity was systemically analyzed to provide reference and assistance for its clinical treatment and research. By searching in the CBM, CNKI, VIP, Wanfang, Pubmed, Springer and Medline databases, clinical randomized controlled trials (RCT) of acupoint catgut-embedding for simple obesity published from Jan, 2009 to July, 2013 were collected while Revman 5. 2 software was applied to perform the Meta-analysis. Totally 19 articles were acquired with 1 658 cases involved. The effective rate was selected as primary outcome measure in 19 articles. The Meta-analysis was performed among homogeneous researches. The results indicated that compared with other therapies, pooled OR of acupoint catgut-embedding was 2.45 with 95% CI [1.81, 3.32]; in the test for overall effect, Z = 5.81, implying the efficacy difference of two therapies was significant in the treatment of simple obesity (P < 0.01). In subgroups analysis, in the event of treatment session with more than 3 months, compared with other therapies, pooled OR of acupoint catgut-embedding was 2.61 with 95% CI [1.53, 4.46]; in test for overall effect, Z = 3.51, implying the efficacy difference of two therapies was significant in the treatment of simple obesity (P < 0.01); in the event of treatment session with less than 3 months, compared with other therapies, pooled OR of acupoint catgut-embedding was 2.38 with 95% CI [1.65, 3.44]; in test for overall effect, Z = 4.46, implying in the treatment of simple obesity the efficacy difference of two therapies was significant (P < 0.01). Compared with electroacupuncture, OR of acupoint catgut-embedding was 1.79, 95% CI [1.08, 2.95] (P = 0.02). Compared with acupuncture, OR of acupoint catgut-embedding was 1.89, 95% CI [1.16, 3.09] (P = 0.01), which explained that compared with electroacupuncture and acupuncture, the efficacy of acupoint catgut-embedding was significantly different. In a word, the clinical efficacy of acupoint catgut-embedding is superior to other therapies in the treatment of simple obesity.

Objective To examine the expression of inhibitory chondroitin sulfate proteoglycans (CSPGs) and in-vestigate their potential effects on neural plasticity in the peri-infarct cortex and ipsilateral thalamus after focal cerebral infarction in hypertensive rats. Methods Twenty-four adult renovascular hypertensive Sprague-Dawley rats per group were subjected to permanent right middle cerebral artery occlusion(MCAO) or sham operation. Twelve rats which were se-lected randomly from per group at each time point were decapitated and their brains were removed and cut into coronal sections at 7 and 14 days post MCAO. The expression of CSPGs, NG2 and Neurocan was examined using immunostaining and western blot. Results All rats displayed neurological deficits to varying degrees and the expression of CSPGs, NG2 and full length Neurocan was increased in the peri-infarct cortex and ipsilateral thalamus at 7 and 14 days (P<0.05). However, there were no significant difference in either expression of CSPGs, NG2 and full-length Neurocan between 7 and 14 days or the expression of C-terminal fragment Neurocan at 7 and 14 days (all P>0.05). Conclusions CSPGs may play a negative role in neural plasticity through induction of inhibitory environment in the peri-infarct cortex and ipsilat-eral thalamus following focal cerebral infarction in hypertensive rats.

Objective To investigate the dynamic levels of autophagy after intimal injury of carotid artery. Meth-ods In this study ,40 male SD rats were randomly assigned to operated(n=20)and control groups(n=20). Balloon inju-ry was induced in the left carotid artery in operated groups .Rats in control groups just received carotid artery exposure without injury. Western blot was used to detect the levels of Beclin-1, LC3 and p62 at the third and seventh days. Immu-nofluorescence was used to examine the expression of Beclin-1 and LC3 at the third and seventh days. Results The ex-pression levels of Beclin-1 and LC3 were increased while the levels of P62 were decreased at the third and seventh days after carotid balloon injury. Beclin-1 and LC3 were present in neointima and medintima. The numbers of both Beclin-1 positive cells and LC3 positive cells were increased at the third and seventh days after carotid injury. The numbers of Be-clin-1 positive cells were 18.60 ± 1.34 in neointima and 6.40 ± 0.55 in medintima at third day, (27.6 ± 2.19 in neointima and 6.40±0.55 in medinitima at the seventh day,(all P=0.000,n=5). The numbers of LC3 positive cells were 10.60±1.52 in neointima and 3.00 ± 0.71 in medintima at third day, (P=0.000,n=5;at the seventh day 21.20 ± 2.49;3.00 ± 0.71,P=0.000,n=5). Conclusions This study domenstrates that autophagy was activated after carotid injury and the chang is dy-namic, which may contribute to neointima formation.

OBJECTIVETo study the factors influencing short-term prognosis of tuberculous meningitis (TBM) in children.

METHODSThe clinical data of 137 hospitalized children with TBM between January 2007 and February 2011 were retrospectively reviewed. A total of 30 potential factors influencing short-term prognosis of TBM were evaluated by univariate analysis and multivariate logistic regression analysis.

RESULTSClinical staging showed that of the 137 children 21 cases (15.3%) were in the early stage, 67 cases (48.9%) in the medium stage and 49 cases (35.8%) in the late stage of TBM. The univariate analysis revealed 8 factors associated with a poor short-term prognosis: clinical stage of TBM (late), coma, positive Babinski signs, cranial nerve involvements, paralysis, seizures, obvious abnormalities in brain computed tomography (CT) or magnetic resonance imaging (MRI) and elevated protein concentrations in cerebrospinal fluid (CSF). Factors associated with a favourable short-term prognosis for TBM included glucocorticoid steroids therapy, positive reaction of PPD skin test and an increased length of stay in hospital. Multivariate logistic analysis revealed two independent risk factors for a poor short-term prognosis: clinical stage of TBM (late) (OR: 11.168, 95%CI: 3.521-35.426) and positive signs of meningeal irritation (OR: 4.275, 95%CI: 1.043-17.521). An increased length of stay in hospital was shown as a favorable factor (OR: 0.893, 95%CI: 0.825-0.968).

CONCLUSIONSLate-stage TBM and positive signs of meningeal irritation suggest a poor prognosis, while an appropriately longer length of stay in hospital may contribute to a favorable short-term prognosis for children with TBM.
