This study was aimed to explore the mechanism ofZi-Bu Pi-Yin Recipe (ZBPYR) on autophagy and endoplasmic reticulum stress (ERS) to improve spleen-yin deficiency diabetes-associated cognitive decline (DACD). Rats were randomly divided into the control (cont) group, the diabetes (DM) group, the spleen-yin deficiency (pi) group, the spleen-yin deficiency diabetes (piDM) group, and the spleen-yin deficiency diabetes + ZBPYR treatment (ZBPYR) group. The expression of microtubule-associated protein 1A/1B-light chain 3 (LC3Ⅱ), inositol-requiring enzymeα (IRE1α), c-Jun N-terminal kinase (JNK) were observed by western blot. The results showed that the expression of LC3Ⅱ in the DM group, pi group and piDM group decreased compared with the cont group (P < 0.05); and the expression of LC3Ⅱ of the ZBPYR group increased compared with the DM group and piDM group (P < 0.05). Compared with the cont group, the p-IRE1α of the DM group and piDM group, as well as p-JNK1 in the pi group and piDM group were increased (P < 0.05). The p-IRE1α and p-JNK1 of the ZBPYR group were decreased compared with the DM group and piDM group (P < 0.05). It was concluded that ZBPYR improved spleen-yin deficiency DACD by regulating autophagy and ERS.

Objective This study aimed to evaluate the effects of in-utero exposure to HIV and ART on pregnancy outcome and early growth of children.Methods This cohort study enrolled 802 HIV-infected pregnant women between October 2009 and May 2018 in Guangzhou,China The women were assigned to receive combination ART (cART) or mono/dual ART or no treatment.The primary outcomes were the combined endpoints of any adverse pregnancy outcome [including ectopic pregnancy,spontaneous abortion,stillbirth,preterm birth,small for gestational age (SGA)] and adverse early growth outcome (including infant death,HIV infection of mother-to-child transmission,and underweight,wasting and stunting of infants at 4 weeks of age).Results Adverse pregnancy outcomes occurred in 202 (35.1％) of all enrolled HIV-infected women,and 121 (31.3％) of all infants exhibited adverse effects on early growth at 4 weeks of age.The rates of adverse pregnancy outcomes,spontaneous abortion,ectopic pregnancy,stillbirth,infant death and perinatal HIV infection were higher among women not receiving ART,compared to those treated with cART or mono/dual ART (P ＜ 0.05).However,women treated with cART had a higher rate of SGA,compared to untreated women (P ＜ 0.05).No differences in early infant growth were observed among the different treatment regimens.Conclusion Our findings underscore the essentiality of prioritizing HIV-positive pregnant women for ART,as even mono/dual ART available in resource-limited countries could improve pregnancy outcomes and infant survival

Objective To evaluate calcium deficiency and demand in pre-puberty twins and to analyze the heritability of serum bone alkaline phosphatase(BALP).Methods A total of 73 pairs of twins aged 9-16 years were examined by BALP test.Microsatellite polymorphism Was used To diagnose the zygosity of twins,while both intraclass correlation coefficient method and Christian formula were perfortled to investigate heritability of serum BALP.Results The results of zygosity diagnosis displayed that 34 pairs of twins were monozygotic(MZ)twins and 39 pairs were dizygotic(DZ)twins.97.9％of the subjects appeared unusual in the activity of BALP,with activity of BALP>250 U/L in 43.1％of subjects and 200-250 U/L in 54.8％of the subjects.The intake of calcium Was unsatisfied in 48.4％of the boys and 39.0％in girls.Less than 10.0％ of the Sllbiects were satisfied with the intake of calcium in each age group while over 45.0％of the snbjects in 10-13 age group were deficient in calcium.Differences between the means of BALP in different sex groups(t=1.633,P=0.105)and different age groups(F=0.323,P=0.924)were not statistically significant.Heritability analysis displayed that intra-class variation.Inter-class variation.Intra-class correlation coefficient were 191.54,1462.22,0.77 in MZ twins,and those were 491.03,1475.57,0.50 in DZ twins respectively with the heritability of BALP activity as 0.54.Conclusion Calcium deficiency Is commonplace in pre-puberty twins.Our data showed that the BALP activity was influenced both by genetic(54％)and environmental(46％)factors.

Objective To investigate the therapeutic effect of human urinary kallidinogenase in patients with acute cerebral infarction and explore the mechanism by blood oxygen level dependent functional magnetic resonance imaging (BOLD-fMRI). Methods twenty-three patients with acute cerebral infarction were randomized into control group (n=11) and treatment group (n=12) to receive conventional treatment and additional human urinary kallidinogenase treatment for 12 to 14 days, respectively. BOLD-fMRI was performed, and the affected forefinger muscle strength and NIHSS score were recorded before and after the treatment. Results In the treatment group, the activated frequency and volume in the sensorimotor cortex (SMC) ipsilateral to the infarct increased significantly after the treatment (11/12 vs 4/12; 99.58±169.41 vs 105.17±197.23, P<0.05). The inerernent in the activated volume in the SMC was significantly greater in the treatment group than in the control group (94.42±51.57 vs 16.09±106.61, P<0.05). The forefinger muscle strength and NIHSS score in the treatment group improved significantly after treatment (2.67±1.44 vs 1.25±1.48; 4.92±2.94 vs 10.42±3.80, P<0.05), and the improvement in NIHSS score was significantly greater in the treatment group than in the control group (5.50±1.31 vs 3.18±2.48, P<0.05). Conclusion The therapeutic effect of human urinary kallidinogenase on acute cerebral infarction is mediated essentially by promoting the activation in the SMC in the functional area of the brain.

OBJECTIVETo evaluate the effectiveness, safety as well as the immunological change (peripheral T cell subpopulation) in patients with idiopathic thrombocytopenic purpura (ITP) treated with lower dose rituximab.

METHODSTwenty-six patients with refractory ITP which were unresponsive to or relapse after steriod and IVIG treatment were treated with rituximab (100 mg per week for four weeks) and intravenous immunoglobulin (IVIG) treatment. Whole blood cell count, serum concentrations of IgG, IgM and IgA, platelet associated (PA)-IgG, PAIgA and PAIgM, peripheral T cell subpopulations, and B cells of CD19(+)/CD20(+) were detected before and after rituximab therapy.

RESULTSComplete response (CR) was achieved in 6 patients (23.1%), response (R) in 10 (38.5%), and non-response (NR) in 10 (38.5%). One patient relapsed after R. The median follow-up time was 5.5 (0.8 - 8) months. The median response and CR time were 27 (1 - 104) and 41 (4 - 109) days, respectively. After the therapy, the serum concentrations of IgG, IgA, IgM, T cells of CD3(+), CD3(+)CD4(+), CD3(+)CD8(+), CD3(-)CD56(+), CD4(+)CD25(+) and CD4(+)CD25(+)FOXP3(+) were not changed, the number of CD4(+)CD25(+)FOXP3(-) T cells decreased (P < 0.05) and CD19(+)CD20(+) B cells significantly decreased (P < 0.01). PAIgG was lower after treatment compared with that before treatment (P < 0.05). There were no severe adverse effects during rituximab therapy.

CONCLUSIONLower dose rituximab may be an effective and safe modality for patients with ITP.

OBJECTIVETo compare the clinical effectiveness of blind intubation through the Cookgas intubating laryngeal airway(CILA) or Fastrach intubating laryngeal mask airway(FT-LMA) for anticipated difficult tracheal intubation.

METHODSEighty-six patients with anticipated difficult tracheal intubation who were undergoing elective plastic surgery under general anesthesia were randomly allocated into CILA group(n=43) and FT-LMA group(n=43) . After general anesthesia being induced and CILA or FT-LMA being inserted, the patients were treated with blind intubation through CILA or FT-LMA. In each case, the number and the time of intubating laryngeal airway(ILA) insertion and blind intubation attempts and ILA removal were recorded. The view of glottis under fiberoptic bronchoscope(FOB) via CILA or FT-LMA was recorded. In addition, noninvasive blood pressure and heart rate were recorded before and after intravenous anesthetic induction, at ILA insertion, at intubation, at ILA removal and every minute thereafter for 5 minutes.

RESULTSCILA or FT-LMA was inserted successfully in all 86 patients. The rate of the first successful insertion was not significantly different between two groups(P>0.05) . In CILA group, the first intubation attempt succeeded in 35 patients;5 and 2 cases were intubated blindly at the second and the third attempt, one patient failed who was intubated successfully by FOB via CILA. In FT-LMA group, 32 patients were intubated successfully at the first attempt, 4 at the second attempt, 3 at the third attempt, and 4 cases failed, three of them were intubated smoothly with FOB through FT-LMA, one failed patient was intubated by FOB. The time of FT-LMA insertion(34.2∓13.9) s was significantly longer when compared with CILA(22.4∓18.9) s (P<0.05) . However, the time of blind intubation through CILA and FT-LMA [(46.0∓26.7) s vs.(51.8∓41.1) s]and the time of ILA removal[(39.3∓11.9) s vs.(35.3∓10.4) s] were not significantly different between groups(P>0.05) . Hemodynamic changes during blind intubation in the two groups showed no significant differences(P>0.05) .

CONCLUSIONSBlind intubation via CILA or FT-LMA is safe and effective for anticipated difficult tracheal intubation. Nevertheless, CILA is easier to be inserted, with relatively higher success rate of blind intubation.

Objective To evaluate the feasibility of the Shikani Optical Stylet (SOS)-guided intubation through a new Intubating Laryngeal Airway (ILA) in anticipated difficult airways caused by scar contracture of the face and neck.
Methods Thirty-three adult patients with anticipated difficult airways undergoing selective faciocervical scar plastic surgery under general anesthesia were enrolled in this study. After anesthesia induction, a size 2.5, 3.5 or 4.5 ILA was inserted. Following good lung ventilation being verified, the SOS preloaded with an endotracheal tube was inserted via the ILA. Once the clear vocal cords came into view under the SOS, the endotracheal tube was advanced through glottis into the trachea.
Results The ILA provided an effective airway in all patients. Intubation was successful at the first attempt on 22/33 (66.7%) occasions and at the second attempt on 6/33 (18.2%). Intubation failed in 5 (15.1%) patients who suffered from severe limitation of head extension due to scar contracture of the neck. These patients’ tracheas were finally intubated using a fibreoptic bronchoscope via the ILA.
Conclusions The SOS-guided intubating method via the ILA is a feasible technique in patients with scar contracture of the face and neck. However, in patients with severe limitation of head extension, the use of SOS cannot be recommended. The SOS can be used as an alternative apparatus when the fibreoptic bronchoscope is not available.

OBJECTIVE: To study the level of neuropsychological development in late preterm infants and early term infants at the age of 1 year. METHODS: A total of 1 257 children with a corrected age of 1 year were enrolled as subjects. According to gestational age at birth, they were divided into an early preterm group (28-33 weeks), a late preterm group (34-36 weeks), an early term group (37-38 weeks), and a full-term group (39-41 weeks). Gesell Developmental Schedules were used to assess the neuropsychological development of the children, and the groups were compared in terms of neuropsychological development at the age of 1 year. RESULTS: There were significant differences in the developmental quotients of the five functional areas (adaptability, gross motor, fine motor, language and social ability) between the four groups at the age of 1 year (P<0.05), and the full-term infants had the highest development quotients, followed by the early term infants, the late preterm infants, and the early preterm infants (P<0.05). The full-term infants had the lowest rate of developmental delay in each functional area, while the early preterm infants had the highest rate (P<0.05). Compared with the full-term infants, the early term infants had a higher risk of developmental delay in adaptability (OR=1.796, P<0.05), and the late preterm infants had a higher risk of developmental delay in adaptability (OR=2.651, P<0.05) and fine motor (OR=2.679, P<0.05), while the early preterm infants had a higher risk of developmental delay in adaptability (OR=4.069, P<0.05), fine motor (OR=3.710, P<0.05), and social ability (OR=3.515, P<0.05). CONCLUSIONS The risk of neuropsychological developmental delay decreases with the increase in gestational age in children at the age of 1 year, with a dose-response effect. There are varying degrees of developmental delay in early term infants and late preterm infants, and health care follow-up for early term infants and late preterm infants should be taken seriously.

Objective:To investigate the relationship between intracranial arterial remodeling and imaging markers in patients with cerebral small vessel disease (CSVD).Methods:One hundred and fifty-six patients with CSVD who were admitted to the Department of Neurology of the Second Affiliated Hospital of Zhengzhou University or the Public People′s Hospital of Xinzheng from January 2020 to May 2022 were selected, and their brain artery remodeling (BAR) score was calculated. The patients with BAR score≤-1 standard deviation (SD) were defined as individuals with constrictive remodeling of intracranial arteries, and the patients with BAR score≥1 SD were defined as individuals with dilated remodeling of intracranial arteries. Imaging markers of CSVD [white matter hyperintensities (WMHs), lacune, cerebral microbleeds, enlarged perivascular spaces, and cerebral atrophy] were quantified, total CSVD load was calculated and patients were divided into low load group (0-2 points, n=91) and high load group (3-4 points, n=65) according to the total CSVD load scores. The correlation between intracranial artery remodeling and various imaging markers of CSVD and total load was analyzed by using univariate analysis and binary Logistic regression analysis. A nomogram prediction model was established and a receiver operating characteristic curve (ROC) was drawn to assess the predictive value of intracranial artery remodeling on high total CSVD load. Results:Dilated intracranial arterial remodeling was an independent influence factor on severe WMHs ( OR=3.66, 95% CI 1.38-9.72, P=0.009), lacune ( OR=3.78, 95% CI 1.17-12.19, P=0.026), cerebral atrophy ( OR=3.11, 95% CI=1.10-8.81, P=0.033), and high total CSVD load ( OR=6.66, 95% CI=2.14-20.77, P=0.001). Age was an independent influencing factor for high total CSVD load ( OR=1.12, 95% CI 1.07-1.16, P<0.01). A nomogram prediction model for high total CSVD load with age and BAR score≥1 SD as dependent variables had a good effect (C-index=0.826) and calibration ( P=0.024). The best cut-off point of ROC curve was 0.50, with an area under the curve of 0.83 (95% CI 0.76-0.89, P<0.01), the sensitivity and specificity of 0.72 and 0.82. Conclusions:Patients with dilated intracranial arterial remodeling may have a heavier CSVD load. Dilated intracranial arterial remodeling may serve as a new biomarker for assessing CSVD, but the mechanism of the association needs further study.

Ferroptosis is a new type of programmed cell death that is closely associated with the pathophysiological process of ischemic stroke. Ferroptosis inhibitors can improve neurological function and provide neuroprotection after cerebral ischemia. Therefore, the role of ferroptosis in ischemic stroke and the regulation of ferroptosis to intervene in the occurrence and development of ischemic stroke have become a research hotspot. This article reviews the molecular mechanism and potential therapeutic targets of ferroptosis during ischemic stroke, hoping to provide new perspectives for the treatment of ischemic stroke.
