Objective To investigate the risk factors which affect complex febrile seizures developing into epilepsy. Methods Retrospective analysis of 162 complex febrile seizure cases was carried out. Results Fifteen out of 35 children who had familial history of epilepsy developed into epilepsy. Twenty out of 55 cases who had neurological abnormalities developed into epilepsy. Nineteen out of 37 cases of who the length between fever and febrile seizure was less than 1 h developed into epilepsy, but only 13 in 125 patients developed into epilepsy when the interval between fever and seizure was more than 1 h. Conclusion The predictive risk factors for complex febrile seizures developing into epilepsies are familial history of epilepsy, abnormal neurological development, and short intervals between fever and febrile seizure activities.

Objective To explore the influence of Clostridium butyricum on the expression of vascular endothelial cell growth factor (VEGF) and its receptor 2 (VEGFR-2), proliferating cell nuclear antigen (PCNA), and tight junction protein claudin-2 in intestinal tissue in newborn rat with necrotizing enterocolitis (NEC). Methods Forty-eight-hour-old Sprague-Dewley (SD) rats were randomly divided into model group, control group, low-dose group, mid-dose group, and high-dose group, 12 rats each. Rats in each group were fed with milk substitute. The NEC model were created by hypoxia and cold stimulation for 3 consecutive days in model group, low-dose group, mid-dose group, and high-dose group. Meanwhile, low-dose group, mid-dose group, and high-dose group were intervened by being fed with Clostridium butyricum 0.2, 0.4, and 0.8 g/(kg·d), respectively. All rats in each group were sacriifced on day 4 and the intestines tissue was obtained. The pathological changes had been observed. The expression of VEGF, PCNA, and claudin-2 were detected by immunohistochemistry. The expression of VEGFR-2 was detected by RT-PCR. Results The intestines pathological scores was signiifcantly different among ifve groups (P?0 . 05 ). Conclusion The expression of VEGF, VEGF-2 , and claudin-2 were higher in rats with NEC, while the expression of PCNA was lower. Supplementation of Clostridium butyricum may protect newborn rats by its act on these factors.

Objective To explore the neuropsychological development in twin premature infants,and to analyze the risk factors for the retardation of development.Methods The premature infants hospitalized in the Neonatal Ward First Affiliated Hospital of Kunming Medical University from Jun.2010 to Jun.2012 were divided into study groups of twin premature infants and a control group of singleton premature infants.The neuropsychological development of 88 premature infants was evaluated at corrected gestational age of 1 year old by Bayley scales of infant development.According to normal lab findings of the Bayley scales of infant development,the premature infants were then divided into abnormal neuropsychological development group [mental development index(MDI) ≤79 scores] and normal neuropsychological development group (MDI ＞ 79 scores),and the data of 2 groups were statistically analyzed.Results The frequency distribution of MDI score in study group showed a skewed distribution,of which 59％ (27/46 cases) had abnormal neuropsychological development (MDI ≤ 79 scores); However,the frequency distribution of MDI score in control group showed an approximate normal distribution,of which only 12％ (5/42 cases) for abnormal neuropsychological development.Head circumference,body length,body weight,MDI,psycho-motor development index of twin premature infants of one-year old were lower than those of the singleton premature infants of the same age,and the differences were statistically significant (all P ＜0.05).The single factor analysis demonstrated that the risk factors for abnormal neuropsychological development (MDI ≤ 79 scores) of twin premature infants were gestational age,birth weight,mother' s gcstational age,the cultural degree of parents,mode of feeding,neonatal hyperbilirubinemia,neonatal hypoglycemia and neonatal sepsis.Multiple regression analysis showed that neonatal hyperbilirubinemia was the independent risk factor for abnormal neuropsychological development of twin premature infants.Conclusions At same gestational age,neuropsychological development of twin premature infants lagged behind singleton premature infants.Neonatal hyperbilirubinemia may be the risk factors for neuropsychological development of twin premature infants,so the earlier management of neonatal hyperbilirubinemia may be beneficial for the neuropsychological development of twin premature infants.

ObjectiveTo investigate the effect of Glutamine (Gln) on the expression of PCNA in intestinal tissue of neo-natal rats with necrotizing enterocolitis (NEC), and to explore the protective mechanism of Gln in intestinal mucosa.Methods Forty-eight neonatal rats at the age of 48 hours were selected, and divided into 4 groups, control group, Gln group, NEC group, NECGln group. Each group had 12 rats. Control group were fed mice milk substitutes; Gln group were fed mice milk substitutes mixed with Gln; NEC group were fed mice milk substitutes and had cold/ hypoxia exposure twice a day for 3 days; NECGln group were exposed to cold stress, hypoxia and treated with Gln mixed in the milk. The expression of PCNA was detected using immunohistochemical method.Results Compared with control group were and Gln group, the general condition was worse, and the weight was decreased in NEC and NECGln group. The inifltrated inlfammatory cells, congestion, edema, intrinsic layer separation were observed in intestinal mucosa in NEC and NECGln group. The intestinal villus was lost in severe in NEC and NECGln group. The PCNA index was 34.17±5.78, 34.42±5.38, 15.00±1.94, 30.67±3.14 in control, Gln, NEC and NECGln group respectively, with signiifcant difference between each groups (H=24.32,P=0.000). The expression of PCNA in NEC group was lower than that in normal, Gln, and NECGln group (P<0.008). The expression of PCNA had no signiifcant difference among normal, Gln, and NECGln group (P>0.008).Conclusions The expression of PCNA in intestinal mucosa was decreased in NEC rats. Gln supplement could raise the expression of PCNA in intestinal mucosa of NEC rats, and accelerate the speed of intestinal mucosa repair.

Objective To investigate the usefulness of different-b-value diffusion weighted imaging (DWI) in patients with early cerebral infarction and obtain the optimal b value of early cerebral infarction.Methods DWI at b-value of 1,000,2,000,and 3,000 s/mm2 was performed for 40 patients within 72 h after the onset of stroke using a GE Signa HDx 3.0T MRI scanner.Post-processing was done by the DWI specific software Function Tool to gain signal intensity and mean apparent diffusion coefficient in the lesions center and the contralateral normal brain tissue,respectively.The sensitivity of conventional MRI and different-b-value DWI was calculated in the diagnosis of early cerebral infarction.Results In 40 patients with early cerebral infarction,the sensitivity of b-values of 1,000,2,000,and 3,000 s/mm2 (DWIb=1 000,DWIb=2 000,DWIb=3 000) and conventional MRI in the diagnosis of early cerebral infarction were 100％,97.5％,97.5％,72.5％,respectively.With b value increased,signal intensity and ADC value declined.Under the condition of different b values,signal intensity and ADC value were statistically significant in region of interest (P＜0.05).Conclusion DWI is superior to conventional MRI scan in monitoring early cerebral infarction.With the increase of b value,the sensitivity is the higher to hyperacute cerebral infarction,the signal contrast is obvious,while signal to noise ratio of the image reduces.It is suggested that brain tissue contrast and the sensitivity to the new cerebral infarction is more predictable on b value =1,000 DWI than on the other DWIs.

Obj ective To determine the value of serum ferrifin (SF) in diagnosing systemic juvenile idiopathic arthritis (sJIA) with macrophage activation syndrome(MAS).Methods In this study,40 patients with sJIA at the First Affiliated Hospital of Kunming Medical University from December 2012 to December 2015 were divided into 2 groups:sJIA group and sJIA with MAS group,while 20 patients with acute fever at the First Affiliated Hospital of Kunming Medical College were selected as a control group.Before and after treatment,SF was measured with radioimmunological method in 3 groups.Statistical analysis was made by undertaking SPSS 18.0 software.Thedata obtained were analyzed by variance,comparison between groups was made by t-test,and the comparison among groups of enumeration data was tested by chi-square.The differences among groups were considered significant (P ＜ 0.05).Results The levels of SF before treatment in the sJIA group,the sJIA with MAS group and the control group were (2 413.50 ±606.73) μg/L,(7 052.77 ± 2 828.43) μg/L and (135.05 ±32.75) μg/L,respectively.The levels of SF in sJIA group and sJIA with MAS group were proved to be greater than those of the control group (F =92.63,P ＜ 0.01).The level of SF in sJIA with MAS group was significantly higher than that of the sJIA group,and the difference between 2 groups was statistically significant (t =9.19,P ＜ 0.01).The level of SF for 95％ patients in sJIA group was ≤4 000 μg/L.The level of SF of 83％ patients in So-JRA with MAS group was ＞4 000 μg/L,and there was a significance between 2 groups(x2 =25.61,P ＜ 0.01).If the criteria of diagnosis of sJIA with MAS was SF above 4 000 μg/L,the sensitivity was 83.33％,specificity was 95.45％,positive predictive value was 93.75％ and negative predictive value was 87.50％.The level of SF after treatment in sJIA group and sJIA with MAS group [(228.40 ± 78.02) μg/L and (259.55 ± 86.46) μg/L] were lower than that before treatment (t =16.53,10.02,all P ＜ 0.01).Conclusions The levels of SF can be abnormally elevated in cases of sJIA with MAS.Taking the SF above 4 000 μg/L as a criteria of diagnosis of sJIA with MAS would contribute to the early diagnosis and reduction of mortality in sJIA patientswith MAS.

[Objective]Using CiteSpace software to visualize and analyse the literature related to acupuncture treatment of post-stroke dysphagia in China,to reveal the dynamics of frontiers and the evolution of hotspots in this field,as well as provide suggestions and references for future research.[Methods]By searching the three major Chinese databases,China National Knowledge Internet(CNKI),Wanfang Data and China Science and Technology Journal Database(VIP),the literature related to acupuncture treatment of post-stroke dysphagia was retrieved between the establishment of these databases and June 2023.Then the data issuance,authors,institutions,keywords clustering and keywords emergence were analyzed and presented in a visualization map or chart with CiteSpace 6.1.R6 software.[Results]After searching and screening,a total of 1 585 relevant literatures were included,and the overall trend of the number of studies within the field showed a steady increase in terms of the number of publications.However,links among study authors are scattered and mostly intra-institutional.At the same time,the connection among institutions for cross-regional collaboration is not close enough.Keywords clustering analysis showed that the type of research in the literature mainly consists overviews and clinical randomized controlled trial(RCT).In terms of treatment approaches,the use of combination of multiple therapies is common.The time zone map reflects the continuous process of refinement of acupuncture therapies,from which the creation of a series of new types of acupuncture therapies could be observed.[Conclusion]The field of acupuncture for the treatment of post-stroke dysphagia is becoming increasingly sophisticated.It is predicted that the combination of acupuncture with other common therapies for the treatment of post-stroke dysphagia will remain a hot research topic in the coming years.Meanwhile,there will be a new trend towards integrating resources and conducting high-quality clinical studies with multi-centre collaboration.

Objective:To evaluate the efficacy and safety of drospirenone and ethinylestradiol tablets (Ⅱ) in Chinese women with dysmenorrhea.Methods:This was a single-arm, open-label, interventional, multicenter, post-authorization safety/effectiveness study of drospirenone and ethinylestradiol tablets (Ⅱ) across 6 treatment cycles, a total of 526 patients were included in the dysmenorrhea subgroup. Visual analog scale (VAS) was used to assess the severity of menstrual pain. Secondary outcomes included unintended pregnancies, bleeding pattern, cycle control and safety.Results:After treated with drospirenone and ethinylestradiol tablets (Ⅱ), VAS of pain had decreased significantly compared with baselines [(49.5±23.7) vs (32.3±24.9) vs (20.7±19.4) vs (18.4±18.7) mm, P<0.01]. From the second cycle to the fifth cycle, the incidence of scheduled bleeding increased from 93.9% (450/479) to 96.4% (431/447). The duration of scheduled bleeding decreased from (5.7±2.7) to (5.4±1.8) days. The incidence of intermenstrual bleeding decreased from 9.0% (43/479) to 5.6% (25/447). 17.5% (92/526) patients reported adverse drug reactions, most frequently reported adverse events were breast pain, nausea, breast swelling, headache, and uterine bleeding. No death occurred during the study. Conclusion:Drospirenone and ethinylestradiol tablets (Ⅱ) is effective for the treatment of dysmenorrhea and has good safety.

Objective To investigate the value of DWI high b value and ADC value in the diagnosis of hyperacute cerebral is-chemia.Methods Adult SD rats were selected and divided into the control and ischemic group by adopting the random number table method,the ischemic group was re-divided into 0.25,0.50,2.00,4.00、6.00 h groups according to the ischemic time,6 cases in each group with a total of 42 cases.The ischemic group conducted the right middle cerebral artery occlusion(MCAO)for performing the head T2WI and DWI scanning(b values were 0,400,800,2 000,3 000 s/mm2),the CNR and SNR values were recorded,rs-T2WI, rs-DWI and relative apparent diffusion coefficient(rADC)were measured.Then the imaging change of ischemic area was observed. The sensitivity and specificity were detected.Results In b=2 000 s/mm2and 3 000 s/mm2,the diagnostic rates of DWI for hyper-acute cerebral ischemia were obviously higher than those in b=400 s/mm2and 800 s/mm2,and when the b values were 400,800, 2 000,3 000 s/mm2,the sensitivities were 16.7%,50.0%,100.0% and 100.0% respectively and the specificities were 16.7%, 50.0%,100.0% and 100.0% respectively.The difference of ADC values under different b values had statistical significance(P<0.05).Conclusion High b value DWI in the diagnosis of hyperacute ischemia is significantly better than that of low b value,espe-cially in the aspect of displaying the lesion at 0.25,0.50 h cerebral ischemia.
