ObjectiveTo observe the effects of Hei Xiaoyaosan on the learning and memory abilities of Alzheimer's disease model mice (APP/PS1 mice), and to explore its mechanism through the inflammatory cascade mediated by nucleotide-binding oligomerization domain-like receptor family pyrin domain-containing 3 (NLRP3)/cysteine aspartate-specific protease (Caspase-1)/gasdermin D (GSDMD) signaling pathway. MethodsSPF-grade 4-month-old APP/PS1 mice were randomly divided into the model group, MCC950 group, and Hei Xiaoyaosan high-, medium-, and low-dose groups. C57BL/6J mice were used as the blank group. After 7 days of adaptive feeding, mice in each group were intervened. The Hei Xiaoyaosan high-, medium-, and low-dose groups were given corresponding doses by gavage (25.79, 12.90, 6.45 g·kg-1·d-1), the MCC950 group was intraperitoneally injected with 10 mg·kg-1·2 d-1, and the blank group received the same volume of physiological saline by gavage. After 90 days of intervention, the learning and memory abilities were assessed using the Y maze and Morris water maze tests. The structural changes of hippocampal neurons were observed by hematoxylin-eosin (HE) staining. The expression of amyloid precursor protein (APP) in the hippocampal CA3 region was detected by immunohistochemistry. Enzyme-linked immunosorbent assay (ELISA) was used to measure the levels of interleukin (IL)-10, IL-18, and IL-1β in the hippocampus. Western blot was applied to detect the protein expression of NLRP3, Caspase-1, GSDMD, and GSDMD-N in the hippocampus. Immunofluorescence was used to detect the co-localization of GSDMD-N and ionized calcium-binding adapter molecule-1 (Iba-1) in the hippocampus. Results① In the Y maze test, compared with the blank group, the spontaneous alternation rate of the model group was significantly reduced (P<0.01). Compared with the model group, the spontaneous alternation rate in the Hei Xiaoyaosan high- and low-dose groups was significantly increased (P<0.01). ② In the Morris water maze test, during the 1-4 days of the location navigation test, the escape latency time of mice decreased with the extension of training time. On day 4, compared with the blank group, the model group showed a significantly increased escape latency (P<0.05). Compared with the model group, the MCC950 group and the Hei Xiaoyaosan low-dose group showed significantly reduced escape latency (P<0.05). In the spatial exploration experiment, compared with the blank group, the number of platform crossings in the model group was significantly reduced (P<0.01). Compared with the model group, the Hei Xiaoyaosan low-dose group showed significantly increased platform crossings (P<0.05). ③ HE staining showed that, compared with the blank group, the hippocampal CA3 cells of the model group were damaged, arranged loosely and irregularly, swollen, with unclear boundaries, and the nuclei were pyknotic and deeply stained. MCC950 and all doses of Hei Xiaoyaosan improved the hippocampal CA3 cell damage in APP/PS1 mice to varying degrees. ④ Immunohistochemical results indicated that, compared with the blank group, the expression of APP in the hippocampal CA3 region was significantly increased in the model group (P<0.01). MCC950 and all doses of Hei Xiaoyaosan could reduce the expression of APP in the hippocampal CA3 region of APP/PS1 mice (P<0.01). ⑤ ELISA results showed that the levels of IL-18 and IL-1β in the hippocampus of mice in the model group were significantly increased, and IL-10 levels were significantly reduced (P<0.01). Compared with the model group, the IL-18 levels in the MCC950 group and the Hei Xiaoyaosan medium- and low-dose groups were significantly reduced (P<0.01). IL-1β levels in the hippocampus of the MCC950 group and Hei Xiaoyaosan high-, medium-, and low-dose groups were significantly decreased (P<0.01). The IL-10 levels in the hippocampus of the MCC950 group and the Hei Xiaoyaosan medium- and low-dose groups were increased (P<0.05, P<0.01). ⑥ Western blot results showed that compared with the blank group, the protein levels of NLRP3, Caspase-1, GSDMD, and GSDMD-N in the hippocampus of the model group were significantly elevated (P<0.01). Compared with the model group, the content of NLRP3 and Caspase-1 in the hippocampus of the treated groups was decreased (P<0.05, P<0.01). The content of GSDMD in the hippocampus of the Hei Xiaoyaosan high-, medium-, and low-dose groups was reduced (P<0.05, P<0.01), and the content of GSDMD-N in the hippocampus of the Hei Xiaoyaosan medium- and low-dose groups was decreased (P<0.05, P<0.01). ⑦ Immunofluorescence results showed that, compared with the blank group, the co-expression of GSDMD-N and Iba-1 in the hippocampus of the model group was significantly increased (P<0.01). Compared with the model group, the co-expression of GSDMD-N and Iba-1 in the treated groups was significantly reduced (P<0.01). ConclusionHei Xiaoyaosan may regulate the NLRP3/Caspase-1/GSDMD signaling pathway to affect the release of inflammatory factors, alleviate neuroinflammation,improve hippocampal histopathological changes,and improve learning and memory deficits,thus providing potential therapeutic benefits for Alzheimer's disease.

This paper reports the maternal and fetal outcomes of three twin pregnancies with chronic hypertension and obstructive sleep apnea-hypopnea syndrome (OSAHS) who were treated with continuous positive airway pressure (CPAP). All three women with twin pregnancies were diagnosed with chronic hypertension. Furthermore, symptoms such as snoring and apnea assisted the diagnosis of OSAHS through polysomnography monitoring. Case 1 was treated with CPAP at 28 gestational weeks. The blood pressure increased gradually after the first month of CPAP treatment, with an elevated urine protein concentration. At 34 gestational weeks, the pregnant woman underwent a cesarean section due to the development of hemolysis, elevated liver enzymes, and low platelet syndrome. Case 2 was treated with CPAP at 11 gestational weeks, with stable blood pressure throughout the pregnancy, and was delivered through cesarean section at 37 weeks of pregnancy. Case 3 started CPAP at 13 gestational weeks for four months, and increased blood pressure and urine protein were observed. Medication brought the blood pressure down, and urine protein became negative. At 32 gestational weeks, a cesarean section was performed because of premature rupture of the membrane. Her CPAP treatment continued till delivery with good maternal and infant outcomes. The treatment outcomes of the three cases suggest that CPAP may prolong the time of blood pressure rise among twin pregnancies where chronic hypertension and OSAHS coexist, which potentially reduces the occurrence of adverse maternal and infant outcomes.

Objective:
The association between school bullying and attention deficit hyperactivity disorder (ADHD) symptoms among students in primary schools and the moderating role of gender was explored to provide scientific evidence for the prevention and control of school bullying.
Methods:
A total of 4 764 students from 2 primary schools in Wuhan were selected using the convenience sampling method in March 2023. The Olweus Bully/Victim Questionnaire and Strengths and Difficulties Questionnaire were used. A Pearson χ 2 test was used to compare differences in school bullying rates among children with and without ADHD symptoms. Pearson correlation analysis and Process 3.3 were used to analyse the association between ADHD symptoms, and school bullying behaviour and the moderating role of gender.
Results:
The reported rate of bullying victims in primary schools was 24.2% and the rate of bullying perpetration was 3.8%. The rate of ADHD symptom detection among primary school students was 5.9%. ADHD symptoms were positively associated with bullying and bullying victim behaviour ( r =0.16, 0.27, P <0.01). Specifically, the association between ADHD symptoms and bullying behavior tended to be stronger among boys than girls ( β boy =0.17, t =11.13; β girl =0.07, t =4.11, P <0.01).
Conclusions
ADHD symptoms are an important factor influencing school bullying behaviors in students, and gender moderates the association. In the process of preventing and controlling school bullying, ADHD symptoms and gender differences should be emphasized and comprehensive interventions should be implemented.

ObjectiveTo explore the influence of "Internet plus" postpartum health care service on postpartum depression, and to provide an evidence for reducing the incidence of postpartum depression and improving the quality of life for postnatal women. MethodsMothers who gave birth between August 1, 2021 and June 30, 2023 lived in the six streets of Xuhui District were selected as the research subjects. The puerperants were randomly divided into the intervention group and the control group according to the order of enrollment using a numerical numbering system, with 210 cases in each of the intervention group and control group. The intervention group adopted the "Internet plus" postpartum health care services, while the control group adopted the conventional postpartum health care services. The risk factors related to postpartum mental health and the incidence of postpartum depression were compared between the two groups. ResultsThere was no statistically significant difference in the scores of postpartum mental health-related risk factors between the two groups at the first 2 weeks and 1st month after delivery (t=0.736 and t=1.260, P>0.05). However, there was a statistically significant difference in the scores of postpartum mental health-related risk factors at the 3rd months after delivery and 6th months after delivery (t=2.089, P<0.05; t=2.655, P<0.05). There was no statistically significant difference in depression scores at the first 2 weeks after the birth (t=0.560, P>0.05). In the 1st month, the 3rd month and the 6th month after delivery, the intervention group adopted the "Internet plus" postpartum health care service, thus the differences in depression scores were statistically significant (t=2.616, t=2.793 and t=3.107, P<0.05). Conclusion"Internet plus" postpartum health care service is conducive to reducing postpartum depression, promoting maternal mental health, and significantly improving the well-being of postnatal women.

This article summarized Professor PENG Qinghua's experience in treatment of dry eyes with principles of "moistening with acrid medicinals". It is believed that the root cause of dry eyes with "yin fluids deficiency" phenomenon is that yang qi deficiency, deficient cold generating, and yin fluids stagnation; yang qi blocking inside, yin fluids fail to move; yin exhaustion and fluid consumption, deficient yang rising. In clinic, "moistening with acrid medicinals" could be the basic therapeutic methods. For patients with yang-deficiency and fluids-stagnation syndrome, acrid and warm medicinals could be used for warming yang and dispersing cold, moving fluids, and transforming yin stagnation, commonly choosing Fuizi (Aconiti Lateralis Radix Praeparata), Ganjiang (Zingiber officinale Rosc), Xixin (Asari Radix et Rhizoma) and so on. If there is spleen yang deficiency, modified Fuzi Lizhong Pill (附子理中丸) could be used, if lung yang deficiency, modified Xiaoqinglong Decoction (小青龙汤) could be used, and if kidney yang deficiency, modified Jinkui Shenqi Pill (金匮肾气丸) could be used. For patients with yang-stagnation and fluids-retention syndrome, acrid and warm and opening medicinals could be used for expelling yang and resolving constraint, unblocking stagnation and moving fluids, to spread yang qi and free yin fluids, commonly choosing Mahuang (Ephedra sinica Stapf), Guizhi (Ramulus Cinnamomi), Chaihu (Bupleuri Radix) and so on. If there is yang stagnation in exterior parts, modified Mahuang Guizhi-Like Formulas (麻桂类方) were commonly used, and for yang stagnation inside the body, modified Sini Powder (四逆散) were commonly used. For patients with yin-deficiency and fluids-exhaustion syndrome, on the basis of tonifying yin and generating fluids medicinals like Xiyangshen (Panax quinquefolius L.), Nanshashen (Adenophorae Radix), Beishashen (Glehniae Radix), Yuzhu (Polygonati Odorati Rhizoma) or Zengye Decoction (增液汤), combined with the method of moistening with acrid medicinals, so yin and yang transforming with each other without dryness, and the common medicinals include Renshen (Ginseng Radix et Rhizoma), Huangqi (Astragali Radix), Roucongrong (Cistanches Herba), Rougui (Cinnamomi Cortex) and so on.

BACKGROUND:Peripheral nerves play an important role in bone metabolism.In clinical practice,the specific impact of nerve injury on bone transport technology needs further study. OBJECTIVE:To investigate the effect of tibial nerve injury on the treatment of tibial slip by single-plane osteotomy. METHODS:Thirty-two patients with tibial bone defects admitted to Tangshan Second Hospital from May 2011 to June 2022 were selected.According to the presence or absence of tibial nerve injury,patients were divided into the tibial nerve injury group(n=16)and the non-tibial nerve injury group(n=16).Both groups were treated with single-plane osteotomy and bone slip.After treatment,the patients were followed up to collect the mineralization zone healing index,external fixation index,docking point healing and needle infection.After the removal of external fixation,the bone healing and functional evaluation were evaluated by a classification of the Association for the Study and Application of the Method of Ilizarov(ASAMI). RESULTS AND CONCLUSION:(1)All 32 patients were followed up for(25.28±4.79)months.There were no significant differences in bone healing time,external fixation time,healing index and external fixation index between the two groups(P>0.05).Needle infection occurred in two cases of the tibial nerve injury group and one case of the non-tibial nerve injury group,all of which were PALEY I,and there was no significant difference between the two groups(P>0.05).The non-union rate of the occlusal end of the tibial nerve injury group was 31%,and that of the non-tibial nerve injury group was 13%;there was no statistical difference between the two groups(P>0.05).The excellent and good rate of ASAMI bone healing score in the two groups was 100%;the excellent and good rate of limb score was 81%in the tibial nerve injury group and 94%in the non-tibial nerve injury group;there was no statistical difference between the two groups(P>0.05).(2)Our research shows that tibial nerve injury has no significant effect on the mineralization speed,external fixation time,union of the occlusal end,infection of the needle tract,and the quality of bone formation in the mineralized area of the single-plane osteotomy.
