Rat models of diabetes were established by injecting streptozocin intraperitoneally.According to random number table,three groups were divided:normal group,diabetic group,and fisetin-treated group.After 24 weeks,all rats were sacrificed.Biochemical parameters of blood and urine samples were tested.The pathological changes were observed by paraffin sections staining with HE.The expression of extracellular matrix proteins was analyzed via PAS and Masson staining.Location of p300 protein expression was analyzed by immunohistochemistry.The protein expressions of p300 and MMP-2 were determined by Western blotting.The mRNA expressions of MMP-2 were analyzed via real-time PCR.The biochemical parameters and kidney pathological images in fisetin-treated group were better than those in diabetic group.The expression of extraeellular matrix proteins was lower than that in diabetic group.Immunohistochemistry analysis showed that among three groups the expression of p300 was mainly in glomeruli,and was also expressed in cell nucleus and cytoplasm and the coloration of fisetin-treated group was weakened as compared with diabetic group.Western blotting analysis showed that the expression of p300 protein in fisetin-treated group was lower than that in diabetic group(P<O.05).The expressions of MMP-2 mRNA and MMP-2 protein were higher than those in diabetic group (P < 0.05).It is suggested that fisetin may attenuate diabetes associated abnormalities in the kidney of rats,owing probably to inhibiting the expressions of p300 and enhancing the expressions of MMP-2.

Objective To investigate the clinical value of ventricular intracranial pressure monitoring in treatment of severe craniocerebral trauma with high intracranial pressure.Methods A retrospective analysis was conducted on forty cases of severe craniocerebral trauma with GCS score of 3-5 undergone bilateral decompressive craniectomy from October 2010 to January 2012.The patients were divided into three groups:Group A (12 cases received craniotomy after the placement of ventricular intracranial pressure probe) ; Group B (15 cases had craniotomy ahead of the probe placement) ; control group (13 cases had probe placement alone).Intracranial pressure control,dose and duration of administration of dehydrator and prognosis were compared among groups.Results Groups A and B showed a better result in aspects of controlling intracranial pressure within 15 mm Hg,dose and duration of mannitol treatment,and prognosis,as compared with control group (P < 0.05).Furthermore,Group A had seven cases of severe disability or in vegetable state,but only three cases in Group B (P < 0.05).Conclusion Ventricular intracranial pressure monitoring can effectively reduce intracranial pressure,raise treatment success rate and decline the use of mannitol in management of severe craniocerebral trauma.
3.New advances in the treatment of stroke-related insomnia
Journal of Apoplexy and Nervous Diseases 2023;40(10):946-950
The treatment of insomnia currently involves drug and non-drug therapies, with varying treatment outcomes. There is no consensus on the treatment option for insomnia in patients in different post-stroke phases. This article provides a detailed literature review of common insomnia treatment methods based on their application in insomnia in the acute phase, subacute phase, and recovery phase following stroke, aiming to provide guidance for the treatment of post-stroke insomnia. Currently, there is a lack of high-quality randomized controlled trials on the treatment of stroke-related insomnia. Existing research does not support the use of benzodiazepine drugs for the treatment of stroke-related insomnia. Studies suggest that sleep hygiene education and cognitive behavioral therapy for insomnia, non-benzodiazepine drugs, melatonin receptor agonists, antihistamine H1 receptor medications, certain sedative antidepressants, orexin receptor antagonists, and traditional Chinese medicine therapy can improve sleep quality in the subacute and recovery phases after stroke, facilitating the recovery of neurological function in patients. However, there is insufficient evaluation of the impact on neurological function recovery and the side effects.

Objective:
To analyze the efficacy of recombinant activated factor Ⅶ a (rF Ⅶ a) on hematonosis with moderate or severe bleeding signs.
Methods:
Of total 16 cases with rF Ⅶ a treatment from May 2013 to May 2016, 8 cases received allogeneic hematopoietic stem cells transplantation (allo-HSCT) and the other were non-transplantation patients. In two groups, there was no significant difference on rF Ⅶ a usage and dosage. 15 patients with acute graft-versus-host disease (aGVHD) after allo-HSCT were control group (without rF Ⅶ a) .
Results:
①The total response rate was 75.0% (6/8) in non-transplantation group and 37.5% (3/8) in transplantation group, respectively. Median interval for hemorrhage stop was 38.5 hours in non-transplantation group and 63.0 hours in transplantation group. The median overall survival (OS) was 201.0 and 29.0 days for non-transplantation group and transplantation group, respectively, and the OS rate was 50.0% (4/8) and 25.0% (2/8) , respectively. The bleeding-related mortality rate was 50.0% (2/4) and 83.3% (5/6) , respectively. ②Of the 16 cases, 9 showed response to rF Ⅶ a treatment and the other 7 cases’bleeding signs did not alleviate. The median OS was 268.0 in 9 cases with response and 24.0 days in 7 cases without response, respectively. ③In patients with intestinal aGVHD complicated with intestinal hemorrhage, the median OS of observation group (

OBJECTIVE:
To investigate the correlation between serum vitamin D levels and index of glucose and lipid metabolism in postmenopausal women with type 2 diabetes mellitus (T2DM).
METHODS:
A total of 44 postmenopausal women with T2DM and 41 healthy postmenopausal women were matched with age, body mass index and menopausal duration. The serum vitamin D was detected by enzyme-linked immuno-sorbent assay (ELISA).
RESULTS:
Compared with the control group, the level of 25(OH)D3 in postmenopausal women with T2DM was lower, with no statistical significance. Multiple regression analysis revealed that only BMI(bj'=-0.372, P<0.05) was independently related to 25(OH)D3 with statistical significance. The percentages of 25(OH)D3 deficiency in all subjects in the control group and in the T2DM group were 84.7%, 80.5%, and 88.6%, respectively. The 25(OH)D3 deficiency in the T2DM group was more prevalent than that in the control group, with no statistical difference (P=0.372). The binary logistic regression analysis showed the serum 25(OH)D3 level was not related to the risk of diabetes.
CONCLUSION
Compared with the control group, a lower 25(OH)D3 level and a higher rate of 25(OH)D3 deficiency is found in T2DM subjects. When rectified by BMI, these is no significant difference. In postmenopausal women, hypovitaminosis D is associated with obesity and dyslipidemia, but not with the risk of T2DM.

Purpose:
The poor retention and ambiguous differentiation of stem cells (SCs) within corpus cavernosum (CC) limit the cell application in erectile dysfunction (ED). Herein, the effects and mechanism of microRNA-145 (miR-145) gene modification on modulating the traits and fate of bone marrow-derived mesenchymal stem cells (BMSCs) were investigated.
Materials and Methods:
The effects of miR-145 on cell apoptosis, proliferation, migration, and differentiation were determined by flow cytometry, cell counting kit-8, transwell assays and myogenic induction. Then, the age-related ED rats were recruited to four groups including phosphate buffer saline, BMSC, vector-BMSC, overexpressed-miR-145-BMSC groups. After cell transplantation, the CC were harvested and prepared to demonstrate the retention and differentiation of BMSCs by immunofluorescent staining. Then, the target of miR-145 was verified by quantitative real-time polymerase chain reaction and immunohistochemical. After that, APTO-253, as an inducer of Krüppel-like factor 4 (KLF4), was introduced for rescue experiments in corpus cavernosum smooth muscle cells (CCSMCs) under the co-culture system.
Results:
In vitro, miR-145 inhibited the migration and apoptosis of BMSCs and promoted the differentiation of BMSCs into smooth muscle-like cells with stronger contractility. In vivo, the amount of 5-ethynyl-2′-deoxyuridine (EdU)+cells within CC was significantly enhanced and maintained in the miR-145 gene modified BMSC group. The EdU/CD31 co-staning was detected, however, no co-staining of EdU/α-actin was observed. Furthermore, miR-145, which secreted from the gene modified BMSCs, dampened the expression of KLF4. However, the effects of miR-145 on CCSMCs could be rescued by APTO-253.
Conclusions
Overall, miR-145 modification prolongs the retention of the transplanted BMSCs within the CC, and this effect might be attributed to the modulation of the miR-145/KLF4 axis. Consequently, our findings offer a promising and innovative strategy to enhance the local stem cell-based treatments.

Objective:To investigate the epidemiological characteristics and transmission chain of COVID-19 in two families, and to provide scientific evidence for effective prevention and control measures.Methods:Field epidemiological investigation was conducted for the COVID-19 cases occurred in two families and the close contacts in a county of Baotou city in Inner Mongolia Autonomous Region. Descriptive statistical analysis on epidemiological data was conducted.Results:The infection source of the COVID-19 cases in the two families was a man who had living history in Wuhan. After his return, his parents were infected by him. A few days later, the members of a neighbor family were found to be infected, and relatives of this family were also infected after dining together repeatedly. Finally, ten confirmed cases and three suspected cases of COVID-19 were detected in the two families.Conclusions:Human-to-human transmission of COVID-19 can occur not only in a family but also in neighborhoods. The cases in two families had close relationship, indicating the necessity to strengthen the health education about COVID-19 prevention and control and the management of groups at high risk to reduce the incidence of COVID-19 in families and neighborhoods.

Objective:To investigate the clinical efficacy of anal dimple anorectoplasty on female infants with congenital anal atresia combined rectal vestibular fistula.Methods:Clinical data of 69 female infants with congenital anal atresia combined rectal vestibular fistula admitted to Department of Pediatric Surgery, the First Affiliated Hospital of Zhengzhou University from July 2012 to July 2022 were retrospectively analyzed.They were divided into 2 groups according to the surgical methods: 34 cases of anal dimple anorectoplasty(group A) and 35 cases of anterior sagittal anorectoplasty(group B). The operation time, length of stay, short-term complications, long-term complications and bowel function (determined by the Rintala score at 6 months postoperatively) of the two groups were compared.The difference in the incidence of postoperative complications between groups was compared by Chi- square test, and the remaining differences between groups were compared by the paired t-test. Results:The operative time [(80.18±9.29) min vs.(103.85±8.26) min] and postoperative hospital stay[(6.10±1.52) d vs.(7.63±2.40) d] in group A were significantly shorter than those of group B ( t=11.40, 2.62; all P<0.05). The Rintala total score at 6 months postoperatively in group A was significantly higher than that of group B[(19.36±0.93) points vs.(18.76±0.44) points]( t=3.20, P<0.05). There were no significant differences in the incidences of short-term [(4/34, 11.8%) vs.(7/35, 20.0%)] and long-term complications [(2/34, 5.9%) vs.(4/35, 11.4%)]between group A and group B ( χ2=0.75, 0.75; all P>0.05). Conclusions:Anal dimple anorectoplasty for female infants with congenital anal atresia combined rectal vestibular fistula is safe and effective.
