ABSTRACT
Objective:To evaluate the effectiveness and safety of preemptive nasogastric tube placement for improving nutritional status and clinical outcomes in hospitalized infants with congenital heart disease.Methods:Children from 0 to 12 months with congenital heart disease hospitalized in cardiovascular center of Children's Hospital of Fudan University from February to July 2018 were selected as control group through continuous sampling. Children hospitalized were selected from September 2018 to February 2019 as intervention group. The control group followed the current feeding method, the intervention group used preemptive nasogastric tube placement. The nutritional indicators, feeding indicators and clinical outcomes of the two groups were compared to evaluate the intervention effect.Results:The serum albumin and prealbumin of the children in the intervention group were (36.81±4.59) g/L and (162.74±48.17) g/L, which were higher than those in the control group (34.80±5.21) g/L and (142.98± 33.96) g/L, the difference between the two groups was statistically significant ( t values were -2.721, -3.169, both P<0.05); the daily enteral intake, calorie intake and single enteral calorie intake of children in the intervention group were (124.93±27.97) ml·kg -1·d -1, (376.48±88.53) kj·kg -1·d -1, (48.39±9.13) kj·kg -1·time -1, higher than the control group (114.74±30.63) ml·kg -1·d -1, (330.01±90.75) kj·kg -1·d -1, (44.24±13.31) kj·kg -1·time -1, the difference between the two groups was statistically significant ( t values were -2.511, -3.750, -2.382, all P<0.05). the incidence of feeding difficulties in the intervention group was 4.95% (5/101) lower than 14.68% (16/109) of the control group, the difference between the two groups was statistically significant ( χ2 value was 5.513, P<0.05); the proportion of children in the intervention group reaching the target feeding amount when discharged from the hospital was 97.03% (98/101), higher than 84.40% (92/109) of the control group, the difference between the two groups was statistically significant ( χ2 value was 9.699, P<0.05). Conclusions:Preemptive nasogastric tube placement is safety and effectively for patients with congenital heart disease in clinical infants. but it still needs a large sample for a long time to confirm its effectiveness.
ABSTRACT
OBJECTIVE@#To observe the clinical effect of high suspension and low incision (HSLI) surgery on mixed haemorrhoids, compared with Milligan-Morgan haemorrhoidectomy.@*METHODS@#A multi-centre, randomized, single-blind, non-inferiority clinical trial was performed. Participants with mixed haemorrhoids from Xiyuan Hospital of China Academy of Chinese Medical Sciences, Beijing Rectum Hospital, Air Force Medical Center of People's Liberation Army of China, and Puyang Hospital of Traditional Chinese Medicine were enrolled from September 2016 to March 2018. By using a blocked randomization scheme, participants were assigned to two groups. The experimental group was treated with HSLI, while the control group was treated with Milligan-Morgan haemorrhoidectomy. The primary outcome was the clinical effect evaluated at 12 weeks after operation. The secondary outcomes included the number of haemorrhoids treated during the operation, pain scores, use of analgesics, postoperative oedema, wound healing, incidence of anal stenosis, anorectal manometry after operation, as well as surgical duration, length of stay and total hospitalization expenses. A safety evaluation was also conducted.@*RESULTS@#In total, 246 eligible participants were enrolled, with 123 cases in each group. There was no significant difference in the clinical effect between the two groups (100.00% vs. 99.19%, P>0.05). Compared with the control group, the number of external haemorrhoids treated during the operation and the pain scores after operation were significantly reduced in the experimental group (P0.05). The surgical duration and length of stay in the experimental group were significantly longer than those in the control group, and the total hospitalization expense was significantly higher than that in the control group (all P<0.05). No adverse events were reported in either group during the whole trial or follow-up period.@*CONCLUSION@#HSLI had the advantages of preserving the skin of anal canal completely, alleviating postsurgical pain and promoting rapid recovery after operation.

Objective:To compare and explore the effects of needling acupoints at different nerve segmentson the oxytocin (OT) neurons in the paraventricular nucleus of hypothalamus (PVN) and the intragastric pressure, and discuss the possible mechanisms. Methods: Thirty-two healthy adult Sprague-Dawley (SD) rats were numbered and divided into 4 groups according to the random number table, a Zusanli (ST 36) group, a Neiguan (PC 6) group, a Weishu (BL 21) group and a control group, with 8 rats in each group. Except the control group, rats in the other three groups received acupuncture at the corresponding acupoints. To observe the differences in double-labeled OT neurons and c-fos neurons of the hypothalamic PVN and the intragastric pressure after acupuncture among the three groups of needling acupoints at different nerve segments. Results:Compared with the control group, the numbers of double-labeled cells in the PVN of the Zusanli (ST 36) group and the Neiguan (PC 6) group decreased significantly, while the intragastric pressure increased significantly (allP<0.05), and the inter-group differences were statistically significant (P<0.05). The intragastric pressure in the Weishu (BL 21) group decreased significantly, and the inter-group difference was statistically significant (P<0.05). Compared with the Weishu (BL 21) group, the numbers of OT/c-fos double-labeled cells in PVN of the Zusanli (ST 36) group and the Neiguan (PC 6) group decreased significantly, and the intragastric pressure increased significantly, the inter-group differences were statistically significant (allP<0.01). Conclusion:Acupoints at different nerve segments have different regulation effects on intragastric pressure. The difference may be related to the different nerve conduction pathways by acupoints at different nerve segments in regulating the intragastric pressure. The PVN may be one common integration center for the regulation of gastric function in the three acupoints [Zusanli (ST 36), Neiguan (PC 6) and Weishu (BL 21)] at different nerve segments.
ABSTRACT
Objective To disscus the applicability of three surveillance methods for Aedes albopictus in dengue risk indication. Methods Larval and adult mosquito surveillance were conducted in two villages of Guangzhou by using three vector monitoring methods. Meteorological data and dengue cases were obtained in the same period. Results The population dynamics of larvae and adult mosquitoes were affected by temperature and their overall trend was consistent, but there were differences between the abundance of larvae and adult mosquitoes. From December to February the next year, Breteau index(BI) ranged from 5.66 to 24.53 with a risk of level 1 to 3 for dengue fever, while the mosquito and oviposition positive index(MOI) and adult-mosquito density index(ADI) were 0 to 4.00 and 0 to 1 per man-hour, respectively, indicating no risk for dengue fever. In March, compared with BI which indicated a risk of level 3, MOI were 2.13 and 3.77, respectively, representing for no risk. ADI were 4 to 6 per man-hour, indicating a risk of level 1 and level 2, respectively. After April, the dengue risk level reflected by each indicator became to be consistent. Conclusions The risk of dengue fever indicated by BI is always higher than or equal to the risk indicated by the other two. Compared with BI, MOI and ADI are more sensitively in reflecting the activity of Ae. albopictus.
ABSTRACT
Objective To investigate the long-term efficacy and prognosis of concurrent chemoradiotherapy alone and concurrent chemoradiotherapy after neoadjuvant chemotherapy for stage ⅡB-ⅢB cervical squamous cell carcinoma. Methods A retrospective analysis was performed among 171 patients with stage ⅡB-ⅢBcervical squamous cell carcinoma who were admitted to our hospital and had complete follow-up data from February 1,2005 to October 31,2011. Results The median follow-up time was 66 months. There were no significant differences in the 3-or 5-year overall survival rates between the concurrent group and the neoadjuvant group(81.4% vs.75.9%,74.3% vs.67.2%,P=0.469).According to the subgroup analysis,there was no correlation between lymph node metastasis and survival curve(P=0.310,P=0.151).The univariate and Cox multivariate analyses showed that tumor size,lymph node metastasis,and concurrent chemotherapy method were independent prognostic factors for cervical cancer(P<0.05).For the patients with lymph node metastasis, the neoadjuvant group had a significantly higher pelvic local recurrence rate than the concurrent group (P=0.047),while there were no significant differences in mortality,distant metastasis,or long-term adverse reactions between the two groups(all P>0.05).For the patients without lymph node metastasis,the neoadjuvant group had a significantly higher incidence of grade 3-4 bone marrow suppression than the concurrent group (P=0.016), while there were no significant differences in mortality,local recurrence,distant metastasis,or long-term adverse reactions between the two groups (all P>0.05). Conclusions Concurrent chemoradiotherapy alone and concurrent chemoradiotherapy after neoadjuvant chemotherapy achieve similar treatment outcomes in patients with stage ⅡB-ⅢBcervical squamous cell carcinoma,no matter whether they have lymph node metastasis or not. Tumor size,lymph node metastasis,and concurrent chemotherapy method are independent prognostic factors.Neoadjuvant chemotherapy increases the risk of grade 3-4 marrow suppression during concurrent chemoradiotherapy,prolongs irradiation time,and increases the risk of local recurrence.
ABSTRACT
Objective@#To explore the clinical features, the serotype distribution and drug resistance of the isolates in patient with invasive pneumococcal disease (IPD).@*Methods@#By retrieving the laboratory information system in 18 children′s hospitals from 2012 to 2017, the children with IPD were enrolled. Streptococcus pneumoniae (Spn) must be isolated from the sterile sites (blood, cerebrospinal fluid, hydrothorax and joint effusion etc.). The clinical characteristics, serotype, drug resistance, treatment and prognosis were reviewed and analyzed. According to the telephone follow up results, the patients were divided into death group and recovered group. The index as an independent risk factor of mortality was demonstrated by multivariate logistic regression analysis.@*Results@#There were 1 138 children with IPD, including 684 male and 454 female. The proportion of male to female was 1.5∶1. The age ranged from one day to 16 years. The median age was 1 year 3 month. The majority was under 5 years of age (89.3%, n= 1 016), especially under 2 years of age (61.9%, n=704). In all cases, 88.2% (n=1 004) were community acquired infection. The infections included meningitis (n=446, 39.2%), pneumonia with bacteremia (n=339, 29.8%), and bacteremia without focus (n=232, 20.4%). Underlying diseases were found in 242 cases (21.3%). Co-infections were determined in 62 cases (5.4%) with mycoplasma, 27 cases (2.4%) with adenovirus and 34 cases with influenza virus (3.0%). The penicillin insensitivity (PNSP) rates in meningitis and non-meningitis isolates were 69.5% (276/397) and 35.9% (221/615), respectively. There were 81 strains serotyped, in which 93.8% (76/81) were covered by 13-valent protein-polysaccharide conjugate vaccine (PCV13). In the 965 patients who were followed up by phone call, 156 cases (16.2%) were confirmed dead. The independent risk factors for the death were under 2 years of age (OR=2.143, 95%CI 1.284-3.577, P=0.004), meningitis (OR=3.066, 95%CI 1.852-5.074, P<0.01), underlying disease (OR=4.801, 95%CI 2.953-7.804, P<0.01), septic shock(OR=3.542, 95%CI 1.829-6.859, P<0.01), disseminated intravascular coagulation (DIC) (OR=4.150, 95%CI 1.468-11.733, P=0.007), multiple organ failure (OR=12.693, 95%CI 6.623-24.325, P<0.01) and complications of central nervous system (OR=1.975, 95%CI 1.144-3.410, P=0.015).@*Conclusions@#Most children with IPD were under 5 years of age, having underlying diseases and acquired the infection in community. The independent risk factors for death were under two years old, meningitis, underlying diseases and multiple organ failure. The problem of drug resistance was severe. The universal immunization of PCV13 would be effective to prevent IPD in Chinese children.
ABSTRACT
Aim To explore the protective effects of naringin on hypoxic ischemic brain injury in neonatal rats and its mechanism. Methods Ninety-six healthy 7-day neonatal SD rats were randomly divided into sham operation group, hypoxic-ischemic brain damage group (HIBD group),HIBD with low-dose naringenin group(50 mg·kg-1, NG-L) and HIBD with high-dose naringenin group(100 mg·kg-1,NG-H). Neu-rological deficit, HE staining and brain water content were measured 48h after operation. Immunoblotting was used to detect the expressions of NOD2,RIP2 and NF-κB. Enzyme linked immunosorbent assay(ELISA) method was adopted to detect TNF-α and IL-1β ex-pression. Results Compared with HIBD group, the neurological deficit score decreased, the pathological damage was reduced, and the water content of brain tissues markedly decreased by naringenin(50,100 mg ·kg-1) treatment(P<0.05). Western blot revealed the down-regulation of NOD2,RIP2 and NF-κB by na-ringenin (50,100mg·kg-1) treatment (P<0.05). The content of TNF-α and IL-1β in brain tissues was lower than that of HIBD group (P <0.05). Conclu-sion Naringenin is likely to exert a protective role in neonatal rats of hypoxic ischemic brain injury perhaps through decreasing the expression of NOD2, RIP2 and NF-κB,and reducing the secretion of TNF-α and IL-1β.
ABSTRACT
Aim To study the therapeutic effect of CpG-ODN, an agonist of Toll-like receptor 9 (TLR9), on hypoxic/ischemic encephapathy in neonatal rats and investigate the mechanisms.Methods Fifty healthy 7-day-old neonatal Wistar rats (in either gender, weighing 12~17g) were randomly divided into sham operation group, HIBD group, and CpG-ODN low group(0.35 mL·kg-1), CpG-ODN middle group(1.40 mL·kg-1), CpG-ODN high group(5.60 mL·kg-1).The neurological function was scored after 48h operation;ten rats of each group was executed respectively and brains tissue was taken;HE staining was used to observe the brain pathological changes.Western blot assay was used to detect the expressions of TLR9 and phosphor-p38 mitogen-activated protein kinases(p-p38 MAPK), and enzyme linked immunosorbent assay (ELISA) method was adopted to detect TNF-α expression.Results The CpG-ODN low, middle group were improved in impairment significantly compared with the HIBD group, and the brain pathological change was lessened, while the CpG-ODN high group was impaired significantly compared with the HIBD group (P<0.05), and brain pathological change was sharpened.Western blot showed the up-regulation in TLR9 and p-p38 MAPK and a significant increase of the expression of TNF-α in the brain tissue in CpG-ODN group with statistical difference in HIBD group and sham operation group(P<0.05).Conclusions The neuro-behavioral score and nervous system function can be improved and the hypoxic/ischemic brain damage can be reduced in neonatal rats in the CpG-ODN low, middle group.The protective mechanisms may be suitably via activating p38 MAPK signaling pathway to promote p38 MAPK phosphory1ation and up-regulation of the expression of TNF-α in the brain tissue of rats.

ABSTRACT
<p><b>OBJECTIVE</b>To study the efficacy of metformin intervention on insulin resistance during catch-up growth in mice with fetal growth restriction (FGR).</p><p><b>METHODS</b>Mouse models of FGR were established by low protein diet feeding of the pregnant mice. Both the newborn female mice with FGR and normal control (NC) mice were randomized for feeding with a standard diet (SF) or a high-fat diet (HF) after weaning and treatment with gavage of either metformin or normal saline. The mice were examined for vaginal opening time and the estrous cycle at the age of 8 weeks. At the age of 12 weeks, 6 mice in anestrus from each group were fasted for 12 h for measurement of body weight, height, poundera index (PI), fasting blood glucose (FBG), fasting insulin (Fins), follicle stimulating hormone (FSH) and anti-Mullerian hormone (AMH), and the HOMA-IR was calculated. The reproductive capacity of female mice was assessed by mixing them with male mice at the ratio of 2:1. The 3 × 2 factorial analysis was conducted to determine the interactions between FGR, high-fat feeding and metformin.</p><p><b>RESULTS</b>Factorial analysis showed that FGR and high-fat feeding had significant effects on the PI index, Fins, HOMA-IR, vaginal opening time, and AMH (P<0.05). Metformin significantly affected the factors related to high-fat feeding including weight, PI, FPG, Fins, HOMA-IR and estrous cycle (P<0.05) and the factors related to FGR with the exception of height and FSH (P<0.05). FGR significantly affected the factors tested except for body weight (P<0.05); high-fat feeding affected all the factors but the FSH (P<0.05); metformin affected all the factors but the height and FSH (P<0.05). In the female mice treated with saline, the pregnancy rates differed significantly between FGR mice with high-fat feeding and control mice with standard feeding, and between FGR mice with standard feeding and high-fat feeding (P<0.05).</p><p><b>CONCLUSION</b>FGR mice can present with delayed puberty with rare ovulation and adulthood insulin resistance, and high-fat feeding after birth can promote the catch-up growth of FGR mice. Metformin intervention is effective for improving insulin resistance and reproductive-endocrine disorders in FGR mice during catch-up growth.</p>
ABSTRACT
TRPA1 channels are non-selective cation channels that could be activated by plant-derived pungent products, including gingerol, a main active constituent of ginger. Ginger could improve the digestive function; however whether ginger improves the digestive function through activating TRPA1 receptor in gastrointestinal tract has not been investigated. In the present study, gingerol was used to stimulate cell lines (RIN14B or STC-1) while depletion of extracellular calcium. TRPA1 inhibitor (rethenium red) and TRPA1 gene silencing via TRPA1-specific siRNA were also used for mechanistic studies. The intracellular calcium and secretion of serotonin or cholecystokinin were measured by fura-2/AM and ELISA. Stimulation of those cells with gingerol increased intracellular calcium levels and the serotonin or cholecystokinin secretion. The gingerol-induced intracellular calcium increase and secretion (serotonin or cholecystokinin) release were completely blocked by ruthenium red, EGTA, and TRPA1-specific siRNA. In summary, our results suggested that gingerol derived from ginger might improve the digestive function through secretion releasing from endocrine cells of the gut by inducing TRPA1-mediated calcium influx.

ABSTRACT
BACKGROUND:Preliminary studies of our research group mainly focus on the role of nucleus of solitary tract in gastric noxious stimulation and acupuncture point, while dorsal nucleus of vagus nerve, nucleus of solitary tract and area postrema are the necessary component for vagus nerve complex, and dorsal nucleus of vagus nerve plays a crucial role in the regulation of gastric functions. OBJECTIVE:To observe the effect of acupuncture at Zusanli, Neiguan, Pishu and Shenshu acupoints on the gastric-related neurons in dorsal motor nucleus of the vagus nerve. METHODS:The gastric related neurons in dorsal motor nucleus of the vagus nerve of gastric distension rats were identified using extracellular recording technique, according to neuroelectrophysiology method. Acupuncture stimulation was given to Zusanli, Neiguan, Pishu and Shenshu for 15 seconds. The effect of body stimulation on the gastric distension related neurons in dorsal motor nucleus of the vagus nerve of rats was recorded. RESULTS AND CONCLUSION:Among the involved 24 rats, 90 neurons at paraventricular hypothalamic necleus exhibited discharge. Among the discharged neurons, 54 neurons were related to gastric distension. After acupuncture stimulation at Zusanli, Neiguan, Pishu and Shenshu, there were 44, 39, 38, 27 neurons giving a response, the reaction rate was 82%, 72%, 70%and 50%, respectively. Acupunture at different nerve segment acupoints can activate the dorsal motor nucleus of the vagus nerve to different degrees, which is involved in the regulation of gastric motility.
ABSTRACT
BACKGROUND:Previous studies concerning neuromechanism of acupuncture for regulating gastric function mainly focused on peripheral nerve, involving in central nervous system. In particular, there are few studies addressing higher central nervous system. OBJECTIVE:To explore the effects of acupuncture at Neiguan (PC6) and Zusanli (ST36) on gastric-related neurons in the hypothalamic paraventricular nucleus. METHODS:Using microelectrode extracellular recording technique, gastric related neurons in the paraventricular nucleus were found in gastric distension rats. Stimulation was conducted for 30 seconds by hand acupuncture at Neiguan and Zusanli. The effects of acupuncture on gastric-related neurons in the paraventricular nucleus were observed. RESULTS AND CONCLUSION:The discharge of 109 neurons in the hypothalamic paraventricular nucleus of 60 rats was recorded. A total of 56 gastric-related neurons of the 109 neurons were observed. The number of neurons response to acupunctures at Zusanli, Neiguan, Pishu (BL20) and Weishu (BL21) were respectively 44, 47, 29, and 33, with the reaction proportion of 78.57%, 83.47%, 51.79%and 58.93%. Results suggested that there exist gastric distension stimulation and acupuncture stimulations from neurons soma to visceral reaction in the hypothalamic paraventricular nucleus, which simultaneously participates in the regulation of acupuncture on the gastric function.

The permeabilities of intact mouse abdominal skin and gloves to aniline were measured by high performance liquid chromatography-diode array detection.</p><p><b>RESULTS</b>The transdermal penetration of the two concentrations of aniline followed zero order kinetics within 12 h, exhibiting total aniline permeabilities within 24 h of 51.71% and 48.31%, respectively. The absorption liquid had an aniline concentration of at least 18 µg/L. The medical disposable latex glove could not stop the penetration of 0.010 mg/ml aniline, but the industrial natural latex glove could.</p><p><b>CONCLUSION</b>The penetration of 0.102 mg/ml and 0.010 mg/ml aniline through the mouse abdominal skin follows zero order kinetics within 12 h. The medical disposable latex glove cannot stop the penetration of 0.010 mg/ml aniline, but the industrial natural latex glove can.</p>
