Osteoporosis(OP) is a senile bone disease characterized by an imbalance between bone remodeling and bone formation. Targeting pathogenesis of kidney deficiency, spleen deficiency, and blood stasis, Bushen Jianpi Huoxue Decoction has a significant effect on the treatment of OP by tonifying kidney, invigorating spleen, and activating blood circulation. MicroRNA(miRNA) and the anti-apoptotic protein B-cell lymphoma-2-like protein 1(BCL2L1) are closely related to bone cell metabolism. Therefore, in this study, the binding of miR-140-5p to BCL2L1 was detected by dual luciferase assay and polymerase chain reaction(PCR). After silencing or overexpressing miR-140-5p, the apoptosis, autophagy, and osteogenic function of human fetal osteoblast cell line 1.19(HFOB1.19) were observed by flow cytometry and Western blot. Bushen Jianpi Huoxue Decoction-containing serum was prepared by intragastric administration of Bushen Jianpi Huoxue Decoction in rats. Different concentrations of Bushen Jianpi Huoxue Decoction-containing serum were used to treat HFOB1.19 with or without miR-140-5p mimic. The expression of osteogenic proteins in each group was observed, and the role of miR-140-5p/BCL2L1 in apoptosis and autophagy of HFOB1.19 was studied, along with the effect of Bushen Jianpi Huoxue Decoction on these processes. As indicated by the dual luciferase assay, miR-140-5p bound to BCL2L1. Flow cytometry and Western blot showed that miR-140-5p promoted apoptosis and inhibited autophagy in HFOB1.19. After intervention with high, medium, and low doses of Bushen Jianpi Huoxue Decoction-medicated serum, compared with the miR-140-5p NC group, the expression of osteocalcin(OCN), osteopontin(OPN), Runt-related transcription factor 2(RUNX2), and transforming growth factor beta 1(TGF-β1) decreased in the miR-140-5p mimic group, while the expression of bone morphogenetic protein 2(BMP2) showed no significant difference under high-dose intervention. Therefore, miR-140-5p/BCL2L1 can promote apoptosis and inhibit autophagy in HFOB1.19. Bushen Jianpi Huoxue Decoction can affect the osteogenic effect of miR-140-5p through BMP2.

Premature ovarian insufficiency(POI) is a manifestation of ovarian aging, with a global incidence of 3.5%. If not addressed in time, POI can rapidly develop into premature ovarian failure(POF). The incidence of POI is mainly related to genetic factors, iatrogenic factors, autoimmunity, aging, infection, psychological factors, and other influences. POI not only causes menstrual disorders, amenorrhea, infertility, and dyspareunia but also tends to present with symptoms such as mood swings, insomnia, hot flashes, fatigue, as well as osteoporosis, coronary heart disease, diabetes, and other conditions, resulting in long-term psychological and physical health concerns for affected women. From traditional Chinese medicine(TCM)'s perspective, POI is primarily attributed to kidney Yin deficiency, with the main pathogenesis rooted in kidney deficiency, which affects the heart, liver, and spleen. It manifests in different syndrome types, including kidney deficiency with liver Qi stagnation, kidney deficiency with blood stasis, and spleen-kidney Yang deficiency. TCM employs a holistic view, utilizing multi-component TCM, multi-site acupuncture, and multi-target and multi-pathway interventions to treat POI. It offers unique advantages such as strong personalization, high safety, and good efficacy. In this paper, the animal and clinical research literature on the prevention and treatment of POI in the past 10 years was systematically summarized and reviewed. It is found that TCM mainly treats POI and alleviates POI-caused issues such as menstrual disorders, infertility, and emotional instability by regulating the neuroendocrine system(hypothalamic-pituitary-ovarian axis, HPOA) and related signaling pathways, improving ovarian function and antioxidant capacity, enhancing immune function, maintaining mitochondrial energy metabolism, inhibiting ferroptosis, and controlling endoplasmic reticulum stress.

Amorphous solid dispersion (ASD) is one of the most effective formulation approaches to enhance the water solubility and oral bioavailability of poorly water-soluble drugs. However, maintenance of physical stability of amorphous drug is one of the main challenges in the development of ASD. Crystallization is a process of nucleation and crystal growth. The nucleation is the key factor that influences the physical stability of the ASD. However, a theoretical framework to describe the way to inhibit the nucleation of amorphous drug is not yet available. We reviewed the methods and theories of nucleation for amorphous drug. Meanwhile, we also summarized the research progress on the mechanism of additives influence on nucleation and environmental factors on nucleation. This review aims to enhance the better understanding mechanism of nucleation of amorphous drug and controlling over the crystal nucleation during the ASD formulation development.

Abstract Gurrently, healthy behaviors are the cornerstone of both physical and mental wellbeing,and more researches are focusing on improving behaviors to alleviate depression among children and adolescents. Based on the concept of 24 h movement behaviors proposed in recent years, the study examines the relationship among physical activity, sedentary behavior, sleep and depressive symptoms in children and adolescents. The research suggests that physical activity could effectively alleviate depression among children and adolescents, and its effectiveness is influenced by factors including type, intensity, duration and frequency of physical activity. Excessive sedentary behavior may increase depressive symptoms, and the impacts of different types, durations, and frequencies of sedentary behavior on depressive symptoms among children and adolescents vary. In addition to its direct impact on depression, sleep could also serve as a mediator among physical activity, sedentary behavior and depression, and there is also a crowdingout effect of time between physical activity and sedentary behavior. Future research should focus on the mechanisms and pathways underlying how 24 h movement behaviors affecting depression among children and adolescents, in order to provide more accurate solutions for the prevention and treatment of depression.

OBJECTIVE: Current clinical evidence on the effects of home blood pressure telemonitoring (HBPT) on improving blood pressure control comes entirely from developed countries. Thus, we performed this randomized controlled trial to evaluate whether HBPT plus support (patient education and clinician remote hypertension management) improves blood pressure control more than usual care (UC) in the Chinese population. METHODS: This single-center, randomized controlled study was conducted in Beijing, China. Patients aged 30-75 years were eligible for enrolment if they had blood pressure [systolic (SBP) ≥ 140 mmHg and/or diastolic (DBP) ≥ 90 mmHg; or SBP ≥ 130 mmHg and/or DBP ≥ 80 mmHg with diabetes]. We recruited 190 patients randomized to either the HBPT or the UC groups for 12 weeks. The primary endpoints were blood pressure reduction and the proportion of patients achieving the target blood pressure. RESULTS: Totally, 172 patients completed the study, the HBPT plus support group ( n = 84), and the UC group ( n = 88). Patients in the plus support group showed a greater reduction in mean ambulatory blood pressure than those in the UC group. The plus support group had a significantly higher proportion of patients who achieved the target blood pressure and maintained a dipper blood pressure pattern at the 12th week of follow-up. Additionally, the patients in the plus support group showed lower blood pressure variability and higher drug adherence than those in the UC group. CONCLUSION HBPT plus additional support results in greater blood pressure reduction, better blood pressure control, a higher proportion of dipper blood pressure patterns, lower blood pressure variability, and higher drug adherence than UC. The development of telemedicine may be the cornerstone of hypertension management in primary care.

Objective:To explore the effect of the care and nursing practice plan based on the timing theory in primary caregivers of infants with infantile spasms.Methods:From July 2019 to June 2020, 80 infants with infantile spasm and 80 primary caregivers in the Department of Neurology of Hunan Children's Hospital were selected as the research object. All infants with infantile spasms were numbered according to the time of admission. The odd-numbered infants were admitted to the First Department of Neurology as the observation group, and the even-numbered children were admitted to the Second Department of Neurology as the control group, with 40 infants and 40 primary caregivers in each group. The control group carried out conventional treatment and nursing, and the observation group implemented a care and nursing practice plan based on the timing theory on the basis of the control group. Before and after the intervention, the Caring Ability Inventory (CAI) , Family Caregiver Task Inventory (FCTI) , Caregiver Burden Inventory (CBI) , and Gesell Developmental Schedules (GDS) were used to evaluate the caring ability, caregiving ability, care load of the primary caregivers of the two groups of infants, and the cognition function of the two groups of infants.Results:After the intervention, the total CAI scores of the primary caregivers in the observation group were higher than those before intervention and those in the control group after the intervention, and the total scores of FCTI and CBI were lower than those before intervention and those in the control group after the intervention, and the differences were statistically significant ( P<0.05) . After the intervention, the developmental quotient (DQ) values of the five energy areas of GDS in the observation group were higher than those before the intervention, and the DQ values of the three energy areas of gross motor, fine motor, and language were higher than those of the control group after the intervention, and the differences were statistically significant ( P<0.05) . Conclusions:The care and nursing practice plan based on the timing theory can improve the caring ability and caregiving ability of the main caregivers of children with infantile spasms, reduce the care load, and improve the cognitive function of the children.

OBJECTIVE: To investigate the current status of antibiotic use for very and extremely low birth weight (VLBW/ELBW) infants in neonatal intensive care units (NICUs) of Hunan Province. METHODS: The use of antibiotics was investigated in multiple level 3 NICUs of Hunan Province for VLBW and ELBW infants born between January, 2017 and December, 2017. RESULTS: The clinical data of 1 442 VLBW/ELBW infants were collected from 24 NICUs in 2017. The median antibiotic use duration was 17 days (range: 0-86 days), accounting for 53.0% of the total length of hospital stay. The highest duration of antibiotic use was up to 91.4% of the total length of hospital stay, with the lowest at 14.6%. In 16 out of 24 NICUs, the antibiotic use duration was accounted for more than 50.0% of the hospitalization days. There were 113 cases with positive bacterial culture grown in blood or cerebrospinal fluid, making the positive rate of overall bacterial culture as 7.84%. The positive rate of bacterial culture in different NICUs was significantly different from 0% to 14.9%. The common isolated bacterial pathogens Klebsiella pneumoniae was 29 cases (25.7%); Escherichia coli 12 cases (10.6%); Staphylococcus aureus 3 cases (2.7%). The most commonly used antibiotics were third-generation of cephalosporins, accounting for 41.00% of the total antibiotics, followed by penicillins, accounting for 32.10%, and followed by carbapenems, accounting for 13.15%. The proportion of antibiotic use time was negatively correlated with birth weight Z-score and the change in weight Z-score between birth and hospital discharge (r=-0.095, -0.151 respectively, P<0.01), positively correlated with death/withdrawal of care (r=0.196, P<0.01). CONCLUSIONS Antibiotics used for VLBW/ELBW infants in NICUs of Hunan Province are obviously prolonged in many NICUs. The proportion of routine use of third-generation of cephalosporins and carbapenems antibiotics is high among the NICUs.

Objective To explore the application value of multimodal image fusion technology in the diagnosis and treatment of intrahepatic cholangiocarcinoma (ICC).Methods The retrospective descriptive study was conducted.The clinicopathological data of 11 patients with ICC who were admitted to Zhujiang Hospital of Southern Medical University between January and September 2018 were collected.There were 5 males and 6 females,aged (55 ± 12)years,with a range from 30 to 74 years.The data of contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI) with gadoxetate disodium (Gd-EOB-DTPA) of the upper abdomen were respectively collected,and three-dimensional(3D) model of liver was constructed based on CT-MRI fusion images.The preoperative evaluation and surgical planning were carried out based on the different modal imaging examination technologies.The indocyanine green (ICG) molecular fluorescence imaging system and augmented reality navigation system were used to guide hepatectomy.Observation indicators:(1) preoperative evaluation;(2) intraoperative situations;(3) comparison between surgical planning based on the different model imaging technologies and actual surgical method;(4) follow-up.Follow-up using outpatient examination and telephone interview was performed to detect postoperative complications up to November 2018.Measurement data with normal distribution were represented as Mean ± SD,measurement data with skewed distribution were represented as M (range).Count data were described as absolute number or percentage and comparisons were analyzed using the paired chi-square test.Results (1) Preoperative evaluation:the proportions of grade 3 and above branch vessels of the portal vein and hepatic vein system and tumor margin by enhanced CT examination and enhanced MRI examination were respectively 11/11,4/11 and 5/11,11/11,with statistically significant differences in above indicators (x2 =4.16,5.14,P＜0.05).The enhanced CT showed 11 liver cancer lesions and enhanced MRI showed 13 lesions (including 2 lesions not demonstrated by enhanced CT,with a maximum diameter ≤ 10 mm).The 3D model of liver based on CT-MRI fusion image:location,number,infiltrating range (tumor boundary),intrahepatic vascular distribution,variation and its spatial relationship with lesions could be stereoscopically,intuitively and comprehensively displayed.(2) Intraoperative situations:of 11 patients,11 lesions were explored with naked eyes;13 lesions were detected by ICG molecular fluorescence imaging system,including 2 lesions showing low uptake lesions in liver and gallbladder specific period by preoperative MRI examinations and intrahepatic metastasis cancer by pathologic examination.Of 11 patients,6 had naked-eye ischemia boundaries around related vessels of hepatic portal ligation;10 with anatomical hepatectomy had hepatic segments or hemihepatic boundary by ICG molecular fluorescence imaging system,including 2 using positive staining and 8 using anti-staining.Among 11 patients,3 (1 combined with local resection of hepatic segment Ⅷ metastases),2,2,1,1,1 and 1 underwent respectively left hepatectomy,left lateral lobectomy of liver,right hepatectomy,extended right hepatectomy,right lobectomy of liver,resection of partial hepatic segment Ⅷ and mesohepatectomy.Seven of 11 patients received regional lymph node dissection and 4 received simple lymph node biopsy.Of 11 patients,1 diagnosed as with bile leakage of liver section underwent suture and ligation treatment with 4-0 Prolene;10 didn't occurred bile leakage.The surgical margin of 11 patients was negative.The operation time,volume of intraoperative blood loss and duration of hospital stay were (240± 118)minutes,(275±249)mL and (13 ± 8) days,respectively.There was no blood transfusion in the perioperative period.(3) Comparison between surgical planning based on the different model imaging technologies and actual surgical method:surgical planning of 3D model based on CT,MRI and CT-MRI fusion image in 6,9 and 11 patients was respectively consistent with actual surgical method.(4) Follow-up:11 patients were followed up for 2-10 months,with a median time of 6 months.Three patients had postoperative complications,2 of which were found in Clavien-Dindo Ⅰ and Ⅱ,including 1 with pleural effusion + peritoneal effusion and 1 with pleural effusion,they were improved after conservative treatment;1 with complication of Clavien-Dindo Ⅲ (postoperative intra-abdominal bleeding) was improved by selective arterial embolization using percutaneous femoral artery puncture.There was no postoperative bile leakage,hepatic failure and death.Conclusion Multimodal image fusion technique is helpful to optimize the preoperative surgical planning,which can assist the recognition of important vessels and real-time navigation of hepatectomy during operation,and improve the safety of operation.

OBJECTIVE: To compare the clinical outcomes of microfracture and autogenous osteochondral mosaic transplantation in the treatment of knee joint cartilage injury. METHODS: A retrospective analysis of 71 patients with articular cartilage defects on the femoral condyles who were by autogenous osteochondral mosaic transplantation or microfracture from February 2011 to February 2016, and these patients were followed up for at least 2 years. According to the sugical procedures, the patients were divided into two groups. In the microfracture group, there were 33 patients, 20 males and 13 females, with a mean age of(28.1±4.2) years old; in the mosaicplasty group, there were 38 patients, 26 males and 12 females, with a mean age of(27.8±3.5) years old. The Lysholm knee score, Hospital for Special Surgery (HSS) knee score and the Ahlbäck classification grade were recorded to evaluate the clinical efficacy. Complications were also recorded. RESULTS: The mean Lysholm scores of the microfracture group and the mosaicplasty group improved from 62.9±6.8 and 60.3±7.5 preoperatively to 77.0±5.4 and 85.8±5.6 post-operatively, respectively(<0.05). Mean HSS scores of the microfracture group and the mosaicplasty group improved from 81.5±7.6 and 79.6±8.6 preoperatively to 88.0±4.7 and 91.9±4.7 post-operatively, respectively(<0.05). The mean Lysholm score and HSS score were significantly higher in the mosaicplasty group than those in the microfracture group at the latest follow-up. One patient in the mosaicplasty group suffered superficial wound infection. During the follow-up, no knee osteoarthritis was observed in two groups. CONCLUSIONS Autogenous osteochondral mosaicplasty and microfracture are proved to be safe and effective procedures for knee articular cartilage defects. However, the mosaicplasty has better clinical outcome than the microfracture.
