Objective:To explore the regulatory effects of Qinghua Liangxue Huluo Decoction on oxidative stress and inflammation in acute radiation enteritis in rats, as well as its impact on the PI3K/Akt pathway. Methods:A total of 36 SD rats were randomly divided into four groups using block randomization, namely the control, model, low-dose group (6.17 g/kg), and high-dose (24.68 g/kg) groups, with nine rats in each group. These rats were exposed to X-ray irradiation at a dose of 17.5 Gy to induce acute radiation enteritis, followed by continuous intragastric administration for seven days pre- and post-irradiation. Seven days post-irradiation, the perianal and fecal conditions of rats in each group were observed, and rectal tissues were collected and ground. Enzyme-linked immunosorbent assay (ELISA) was employed to assess the activity of superoxide dismutase (SOD), catalase (CAT) expression, and malondialdehyde (MDA) levels indicative of lipid peroxidation. Quantitative real-time polymerase chain reaction (qRT-PCR) was utilized to analyze the mRNA expression of tumor necrosis factor-ɑ (TNF-ɑ), interleukin-6 (IL-6), and interleukin-1β (IL-1β) in the rectal tissues of each group. Additionally, Western blot was conducted to examine the expression of proteins associated with the PI3K/Akt signaling pathway in rectal tissues. The IEC-6 cells were categorized into the control, radiation, blank, and drug administration groups, with all these groups except for the control group subjected to 10 Gy single irradiation. ELISA was then employed to determine the concentrations of SOD, CAT, MDA, TNF-ɑ, IL-6, and IL-1β in cell supernatants, while Western blot was utilized to assess the expression of PI3K/Akt signaling pathway-related proteins in each group.Results:Compared to the model group, rats in the low-dose and high-dose groups exhibited a trend toward normal perianal and fecal conditions, increased SOD activity ( t = 4.86, 8.50, P < 0.05), elevated CAT expression ( t = 8.72, 14.28, P<0.05), and decreased MDA level ( t = 6.94, 10.66, P < 0.05). Furthermore, the mRNA expression of TNF-ɑ, IL-6, and IL-1β in rectal tissues was significantly inhibited in both low-dose and high-dose groups ( t = 5.60, 2.95, 4.31, 9.16, 4.66, 13.35, P < 0.05), along with lower p-PI3K/PI3K and p-Akt/Akt ratios in rectal tissues compared to the model group ( t = 22.35, 13.56, 18.23, 13.85, P < 0.05). Compared to the radiation group, the drug administration groups (10% drug-containing serum) exhibited increased SOD and CAT expressions ( t = 6.85, 10.44, P < 0.05), as well as decreased MDA expression ( t = 10.44, P < 0.05), in the supernatant. Furthermore, compared to the radiation group, this group displayed significantly inhibited TNF-ɑ, IL-6, and IL-1β concentrations in the cell supernatant ( t = 12.07, 6.87, 14.80, P < 0.05), while lowering p-PI3K/PI3K and p-Akt/Akt ratios in cells ( t = 10.95, 5.59, P < 0.05). Conclusions:Qinghua Liangxue Huluo Decoction demonstrates the potential for mitigating oxidative stress-induced injury and suppressing the expressions of inflammatory factors in rats with acute radiation enteritis. The mechanism behind the potential is likely associated with the negative regulation of the PI3K/Akt signaling pathway.

We reported a case of microcephaly-capillary malformation(MIC-CAP)caused by STAMBP gene variant,in order to improve the clinical diagnosis and treatment.The patient is a 3-month-old male with recurrent convulsions and the main clinical manifestations are multiple forms of seizures,microcephaly,multiple small capillary malformations in the skin,and generalized hypotonia.The genetic test showed that a heterozygous variant in the STAMBP gene was present in the child.Both parents were heterozygous carriers.He was administrated various anti-seizure medications and ketogenic diet,but still had frequent seizures.He then underwent corpus callosotomy,and was followed up until he was 4 years and 10 months old.The post operational outcome was grade IV on Engel's classification.Based on the clinical data of 22 patients in literature,in addition to severe psychomotor retardation,microcephaly,and cutaneous capillary malformations,early-onset drug-refractory epilepsy is also a major feature of MIC-CAP syndrome,which is clinically rare and has a poor prognosis;Callosotomy may help to reduce seizures in the short term.However,the long-term outcome is poor.STAMBP gene is the main responsible gene for this syndrome.

Objective:Compared to imprecisely repetitive transcranial magnetic stimulation (rTMS) over the left dorsolateral prefrontal cortex (DLPFC), this study aimed to explore whether localizing the DLPFC precisely or targeting on the right orbital frontal cortex (rOFC) can improve the rTMS efficacy for the treatment of depressive disorder.Methods:From January 2018 to March 2021, this study recruited patients who met the DSM-Ⅳ diagnostic criteria for depressive disorder in Shanghai Mental Health Center. Nineteen patients were located in the imprecise DLPFC group, 19 patients in the precise DLPFC group, and 14 patients in the rOFC group. All patients were assessed by the 17-item Hamilton Depression Scale (HAMD 17) and Hamilton Anxiety Scale (HAMA) at baseline and after 10-session rTMS treatments. The primary outcome of this study was the HAMD 17 response rate, and the second outcome included the reduction score and reduction ratio of the HAMD 17/HAMA. Results:At baseline, there was no significant group difference in HAMD 17 or HAMA scores among the three groups. After the rTMS treatment, the HAMD 17 response rate was significantly different among the three groups (χ2=6.86, P=0.032). The HAMD 17 response rate in the precise DLPFC group (74%) was significantly higher than that in the imprecise DLPFC group (32%, χ2=6.76, P=0.011), but was comparable with that in the rOFC group (57%, χ2=2.16, P=0.133). HAMD 17 response rate did not significantly differ between the precise DLPFC group and the rOFC group (χ2=0.99, P=0.266). The HAMD 17 reduction score tended to be significantly different among the three groups ( F=2.95, P=0.062), with the precise DLPFC group presented the highest HAMD 17 reduction score. There were no significantly differences in the reduction score of HAMD and the reduction ratio of HAMA and HAMD 17 among the three groups. Conclusions:Precisely localizing the DLPFC target may be helpful to improve the rTMS efficacy for the treatment of depressive disorder, while rOFC may be a candidate target for rTMS treatment of the depressive disorder.

Objective:To explore the association between sleep duration, sleep quality and the prevalence of hypertension in the elderly aged 65 years and above.Methods:This study was conducted among the elderly in communities in Yiwu, China from April to July, 2019, and participants were recruited through physical examination in the hospital. Face-to-face interview was performed to obtain basic information. Sleep duration and sleep quality were evaluated by Pittsburgh Sleep Quality Index (PSQI). Associations between sleep duration, sleep quality and hypertension were evaluated by multivariate logistic regression analysis.Results:A total of 3 169 elderly persons, aged ≥65 years old, were included in the study. The overall prevalence of hypertension was 50.8%. The elderly with very poor sleep quality and short sleep duration accounted for 22.4% and 28.5%, respectively. After adjusting for demographic characteristics, socioeconomic status, lifestyle and health status, the OR of hypertension for the elderly with very poor sleep quality was 1.42 (95% CI: 1.12-1.80) compared with those with very good sleep quality. Compared with the elderly with sleep duration of 6-7 h a night, the OR of hypertension for those with sleep duration <6 h was 1.37 (95% CI: 1.15-1.65). As the sleep quality decreased, the risk for hypertension increased. An U-shaped association was found between sleep duration and risk of hypertension. Subgroup analyses showed that this association existed in both men and women, but only significant in the elderly aged <75 years. Conclusion:Poor sleep quality and short sleep duration were associated with risk for hypertension in the elderly.

Objective:To investigate the effects of microRNA-182-5p (miR-182-5p) on cell proliferation and invasion of esophageal squamous cell carcinoma (ESCC) and its related molecular mechanisms.Methods:Real-time quantitative polymerase chain reaction (RT-qPCR) was employed to detect the miR-182-5p expression in ESCC tissues and cells. MiR-182-5p inhibitor, miR-182-5p mimic and negative control (NC) were transfected into ESCC Eca109 and TE1 cells, and miR-182-5p expression after transfection was examined using RT-qPCR. Cell counting kit-8 (CCK-8) was utilized to investigate the cell proliferation and Transwell chamber was used to detect the cell invasion ability. Dual-luciferase reporter assay was used to detect the direct interaction of miR-182-5p and cell adhesion molecule 2 (CADM2), RT-qPCR was employed to detect CADM2 expression in ESCC tissues, the correlation between CADM2 and miR-182-5p was also examined. Finally, western blot was used to detect the protein expressions of CADM2, focal adhesion kinase (FAK), p-Akt and Akt after transfection.Results:The miR-182-5p level in ESCC tissues was (2.180±1.295), significantly higher than (0.890±0.284) in normal esophageal epithelial tissues ( P<0.001). The survival ratio of ESCC patients with high miR-182-5p level was evidently lower than that of ESCC patients with low miR-182-5p level ( P<0.05). MiR-182-5p expression was significantly associated with TNM staging and lymph node metastasis ( P<0.05). The expressions of miR-182-5p in ESCC cells including EC9706, Eca109, TE1, KYSE450 and KYSE70 were (2.449±0.082), (2.965±0.088), (4.873±0.258), (1.338±0.045) and (1.999±0.082), respectively, obviously higher than (0.989±0.087) in normal esophageal epithelial cell Het-1A (all P<0.01). Besides, miR-182-5p inhibitor significantly downregulated the miR-182-5p expression in Eca109 and TE1, and suppressed cell proliferation and invasion ability. Conversely, miR-182-5p mimic significantly upregulated the miR-182-5p expression in Eca109 and TE1, and promoted cell proliferation and invasion ability. Dual-luciferase reporter assay revealed that co-transfection of CADM2-3′UTR-WT and miR-182-5p mimic significantly reduced the luciferase activities in Eca109 and TE1 cells ( P<0.01), and CADM2 was the direct target of miR-182-5p. The expression of CADM2 in ESCC tissues was (0.190±0.143), markedly lower than (0.845±0.327) in normal esophageal epithelial tissues ( P<0.001). The miR-182-5p level exhibited negative correlation with CADM2 level in ESCC tissues ( r=-0.5004, P<0.001). In addition, CADM2 expression was closely correlated with TNM staging and lymph node metastasis ( P<0.05). The survival ratio of ESCC patients with high CADM2 level was evidently higher than that of ESCC patients with low CADM2 level ( P<0.05). MiR-182-5p inhibitor significantly upregulated the expression of CADM2 protein, but suppressed the protein expressions of FAK, p-Akt and Akt, whereas miR-182-5p mimic markedly downregulated the expression of CADM2 protein, but promoted the protein expressions of FAK, p-Akt and Akt. Conclusion:MiR-182-5p is implicated in the carcinogenesis and development of ESCC, and thus may be a potential molecular target for ESCC patients.
