ObjectiveTo investigate the therapeutic effect of Baihe Wuyaotang (BWT) on non-alcoholic fatty liver disease (NAFLD) and elucidate its underlying mechanism. MethodC57BL/6J mice were randomly assigned to six groups: normal control, model, positive drug (pioglitazone hydrochloride 1.95×10-3 g·kg-1), and low-, medium-, and high-dose BWT (1.3,2.5 and 5.1 g·kg-1). Following a 12-week high-fat diet (HFD) inducement, the mice underwent six weeks of therapeutic intervention with twice-daily drug administration. Body weight was monitored weekly throughout the treatment period. At the fifth week, glucose tolerance (GTT) and insulin tolerance (ITT) tests were conducted. Subsequently, the mice were euthanized for the collection of liver tissue and serum, and the subcutaneous adipose tissue (iWAT) and epididymal adipose tissue (eWAT) were weighed. Serum levels of total triglycerides (TG) and liver function indicators,such as alanine aminotransferase (ALT) and aspartate aminotransferase (AST), were determined. Histological examinations, including oil red O staining, hematoxylin-eosin (HE) staining, Masson staining, and transmission electron microscopy, were performed to evaluate hepatic lipid deposition, pathological morphology, and ultrastructural changes, respectively. Meanwhile, Western blot and real-time quantitative polymerase chain reaction (Real-time PCR) were employed to analyze alterations, at both gene and protein levels, the insulin signaling pathway molecules, including insulin receptor substrate 1/2/protein kinase B/forkhead box gene O1 (IRS1/2/Akt/FoxO1), glycogen synthesis enzymes phosphoenolpyruvate carboxy kinase (Pepck) and glucose-6-phosphatase (G6Pase), lipid metabolism-related genes stearoyl-coA desaturase-1 (SCD-1) and carnitine palmitoyltransferase-1 (CPT-1), fibrosis-associated molecules α-smooth muscle actin (α-SMA), type Ⅰ collagen (CollagenⅠ), and the fibrosis canonical signaling pathway transforming growth factor-β1/drosophila mothers against decapentaplegic protein2/3(TGF-β1/p-Smad/Smad2/3), inflammatory factors such as interleukin(IL)-6, IL-8, IL-11, and IL-1β, autophagy markers LC3B Ⅱ/Ⅰ and p62/SQSTM1, and the expression of mammalian target of rapamycin (mTOR). ResultCompared with the model group, BWT reduced the body weight and liver weight of NAFLD mice(P<0.05, P<0.01), inhibited liver lipid accumulation, and reduced the weight of white fat: it reduced the weight of eWAT and iWAT(P<0.05, P<0.01) as well as the serum TG content(P<0.05, P<0.01). BWT improved the liver function as reflected by the reduced ALT and AST content(P<0.05, P<0.01). It improved liver insulin resistance by upregulating IRS2, p-Akt/Akt, p-FoxO1/FoxO1 expressions(P<0.05). Besides, it improved glucose and lipid metabolism disorders: it reduced fasting blood glucose and postprandial blood glucose(P<0.05, P<0.01), improved GTT and ITT(P<0.05, P<0.01), reduced the expression of Pepck, G6Pase, and SCD-1(P<0.01), and increased the expression of CPT-1(P<0.01). The expressions of α-SMA, Collagen1, and TGF-β1 proteins were down-regulated(P<0.05, P<0.01), while the expression of p-Smad/Smad2/3 was downregulated(P<0.05), suggesting BWT reduced liver fibrosis. BWT inhibited inflammation-related factors as it reduced the gene expression of IL-6, IL-8, IL-11 and IL-1β(P<0.01) and it enhanced autophagy by upregulating LC3B Ⅱ/Ⅰ expression(P<0.05)while downregulating the expression of p62/SQSTM1 and mTOR(P<0.05). ConclusionBWT ameliorates NAFLD by multifaceted improvements, including improving IR and glucose and lipid metabolism, anti-inflammation, anti-fibrosis, and enhancing autophagy. In particular, BWT may enhance liver autophagy by inhibiting the mTOR-mediated signaling pathway.

Objective:To analyze the factors that influence the height development of children and adolescents aged 3 to 16 years in Chengguan District of Lhasa of Xizang Autonomous Region, China.Methods:During the period from August 2021 to June 2022, a convenient sampling method was used to select 100 children and adolescents aged 3-16 years residing in Chengguan District of Lhasa of Xizang Autonomous Region, China. The subjects' physical measurement indicators, Tanner stage, height development questionnaire, wrist bone age, sex hormones, and nutritional biochemical indicators were carefully collected. The factors that influence height development were analyzed using univariate and multivariate logistic regression analyses. Furthermore, the receiver operating characteristic (ROC) curves were constructed to visualize the effects of these influential factors.Results:The study involved a total of 100 children and adolescents, with 51 (51.0%) participants in the tall stature group and 49 (49.0%) participants in the low stature group. Significant differences were observed between the two groups in terms of height difference relative to the national average, body weight, waist circumference, luteinizing hormone level, the percentage of individuals with an abnormal luteinizing hormone level, follicle stimulating hormone level, and bone age [ χ2 ( t) = 13.6, 2.65, 2.47, -2.58, 10.9, -2.95, 11.8, all P < 0.05]. A univariate logistic regression analysis revealed that body mass, waist circumference, the percentage of individuals with an abnormal luteinizing hormone level, follicle stimulating hormone level, and bone age are factors that possibly affect height development ( OR = 1.05, 1.05, 4.56, 1.18, 2.99, all P < 0.05). Furthermore, a multivariate logistic regression analysis revealed waist circumference, the percentage of individuals with an abnormal luteinizing hormone level, and bone age as independent factors influencing height development ( OR = 1.10, 7.01, 3.14, all P < 0.05). The receiver operating characteristic (ROC) curve analysis showed that the values of the area under the curve were 0.65, 0.65, 0.67, and 0.75 respectively for waist circumference, the percentage of individuals with an abnormal luteinizing hormone level, bone age, and their combination (all P < 0.05). Conclusion:Waist circumference, the percentage of individuals with an abnormal luteinizing hormone level, and bone age appear to be critical factors influencing the height development of children and adolescents In Chengguan District of Lhasa of Xizang Autonomous Region, China.

Methods:
(i) Animal experiments. This study conducted experiments using specific pathogen-free (SPF) grade male C57BL/6J wild-type (WT) mice and APP/PS1 double transgenic mice. The animals were divided into three groups: WT group (WT mice, n = 5, receiving distilled water daily), APP/PS1 group (APP/PS1 double transgenic mice, n = 5, receiving distilled water daily), and BSTSD group [APP/PS1 double transgenic mice, n = 5, treated with BSTSD suspension at a dosage of 27 g/(kg·d) for 90 d]. Cognitive function was assessed using the Morris water maze (MWM). Post-experiment, hippocampal tissues were collected for analysis of pyramidal cell and synaptic morphology through hematoxylin-eosin (HE) staining and transmission electron microscopy (TEM). (ii) Cell experiments. The HT-22 cells were divided into control group (untreated), Aβ25-35 group (treated with 20 μmol/L Aβ25-35 for 24 h), icariin group (pre-treated with 20 μmol/L icariin for 60 min, followed by 20 μmol/L Aβ25-35 for an additional 24 h), and icariin + LY294002 group [treated with 20 μmol/L icariin and 20 μmol/L LY294002 (an inhibitor of the phosphoinostitide 3-kinases (PI3K) signaling pathway) for 60 min, then exposed to 20 μmol/L Aβ25-35 for 24 h], and cell viability was measured. Western blot was used to detect the expression levels of synapse-associated proteins [synaptophysin (SYP) and postsynaptic density-95 (PSD-95)] and PI3K signaling pathway associated proteins [phosphorylated (p)-PI3K/PI3K, p-protein kinase B (Akt)/Akt, and p-mechanistic target of rapamycin (mTOR)/mTOR].
Results:
(i) Animal experiments. Compared with APP/PS1 group, BSTSD group showed that escape latency was significantly shortened (P < 0.01) and the frequency of crossing the original platform was significantly increased (P < 0.01). Morphological observation showed that pyramidal cells in the hippocampal CA1 region were arranged more regularly, nuclear staining was uniform, and vacuole-like changes were reduced after BSTSD treatment. TEM showed that the length of synaptic active zone in BSTSD treatment group was increased compared with APP/PS1 group (P < 0.01), and the width of synaptic gap was decreased (P < 0.01). (ii) Cell experiments. Icariin had no obvious toxicity to HT-22 cells when the concentration was not more than 20 μmol/L (P > 0.05), and alleviated the cell viability decline induced by Aβ25-35 (P < 0.01). Western blot results showed that compared with Aβ25-35 group, the ratios of p-PI3K/PI3K, p-Akt/Akt and p-mTOR/mTOR in icariin group were significantly increased (P < 0.01), while the protein expression levels of SYP and PSD-95 were increased (P < 0.01). These effects were blocked by LY294002 (P < 0.01).
Conclusion
BSTSD and icariin enhance cognitive function and synaptic integrity in AD models and provide potential therapeutic strategies through activation of the PI3K/Akt/mTOR pathway.

By sorting out and analyzing the contents about pulse diagnosis in Tanksuqnameh, it was found that in terms of pulse theory, the book contains academic viewpoints of different periods and doctors about three portions and nine readings pulse method and nutritive qi operation law in Huang Di Nei Jing, the Cunkou pulse-taking method and the Cunguanchi theory in Nan Jing, the Renying and Qikou pulse-taking method and the three-region pulse-taking method in Mai Jing, and the seven superficies-indicating, eight interior-indicating and nine channels pulse of Mai Jue, etc.; in terms of pulse theory interpretation, multiple annotations from famous doctors are cited, and TCM basic theories and knowledge of astronomy and mathematics are applied, combined with the background of ancient Iranian medicine and local medical experience for explanation; in terms of pulse diagnosis techniques, pulse diagnosis techniques such as "three fingers determining three guan", "adjusting finger density", "floating and sinking pulse", "foot back pulse breaking life and death" were recorded in books of Nan Jing, Mai Jue, Lei Zheng Huo Ren Shu, etc.; in terms of influencing pulse factors, the male and female pulse, physical pulse, and four time pulse were recorded. Tanksuqnameh is a universal work of Persian Traditional Chinese Medicine, compiled by the author Rashid-ul-Din based on his research on Chinese culture and medical knowledge, combined with the unique customs, language and culture, and way of thinking in the Middle East region, to reorganize various pulse theories from before the Han Dynasty to the Tang and Song Dynasties in China. The publication of this book indicates that TCM pulse diagnosis had been promoted to the Middle East in the 14th century and provided valuable experience for local medical development. The author's sense of identification and research spirit towards different cultures provide a historical example for achieving cross-cultural communication between TCM and medicine in different regions. The preserved literature from the Tang and Song Dynasties in the book can provide clues for a deeper understanding of ancient pulse theory in TCM, but some details do not explain thoroughly or does not match the current clinical practice. Therefore, attention should be paid to distinguishing in research and application.

Objective:To explore the sequential chemotherapy efficacy of different chemotherapeutic regimens in ovarian epithelial carcinoma, fallopian tube carcinoma, and primary peritoneal carcinoma.Methods:A retrospective analysis was conducted on clinical and pathological data of 100 patients with platinum-sensitive ovarian epithelial carcinoma, fallopian tube carcinoma, and primary peritoneal carcinoma treated at Peking University Peopel′s Hospital from January 1992 to January 2019. All patients underwent staging surgery or cytoreductive surgery followed by adjuvant chemotherapy. Based on different postoperative adjuvant chemotherapy regimens, patients were divided into the sequential chemotherapy group (70 cases) and the conventional chemotherapy group (30 cases). Clinical and pathological characteristics, chemotherapy efficacy, adverse reactions, and prognosis were compared between the two groups.Results:(1) Clinical and pathological characteristics: the age, tumor types (including ovarian epithelial carcinoma, fallopian tube carcinoma, and primary peritoneal carcinoma), pathological types, International Federation of Gynecology and Obstetrics (FIGO) stage, postoperative residual disease size, presence of neoadjuvant chemotherapy, and total number of chemotherapy cycles were compared between the sequential chemotherapy group and the conventional chemotherapy group. There were no statistically significant differences observed in these characteristics between the two groups (all P>0.05). (2) Chemotherapy efficacy: the median sum of complete response (CR)+partial response (PR) duration in the sequential chemotherapy group was 80.0 months (range: 39 to 369 months), whereas in the conventional chemotherapy group, it was 28.0 months (range: 13 to 52 months). A statistically significant difference was observed between the two groups ( Z=-7.82, P<0.001). (3) Chemotherapy adverse reactions: in the sequential chemotherapy group, 55 cases (79%, 55/70) experienced bone marrow suppression and 20 cases (29%, 20/70) had neurological symptoms. In the conventional chemotherapy group, these adverse reactions occurred in 11 cases (37%, 11/30) and 2 cases (7%, 2/30), respectively. Statistically significant differences were observed between the two groups for both bone marrow suppression and neurological symptoms (all P<0.05). For the other chemotherapy adverse reactions compared between the two groups, no statistically significant differences were observed (all P>0.05). (4) Prognosis: during the follow-up period, the recurrence rate in the sequential chemotherapy group was 73% (51/70) and in the conventional chemotherapy group was 100% (30/30). The median sum of recurrence-free interval was 70.5 months (range: 19 to 330 months) in the sequential chemotherapy group and 15.0 months (range: 6 to 40 months) in the conventional chemotherapy group. Statistically significant differences were observed between the two groups for both recurrence rate and median recurrence-free interval (all P<0.01).In the sequential chemotherapy group, the median progression-free survival (PFS) time was 84.0 months (range: 34 to 373 months), and the median overall survival (OS) time was 87.0 months (range: 45 to 377 months). In contrast, in the conventional chemotherapy group, the median PFS time was 30.5 months (range: 14 to 60 months), and the median OS time was 37.5 months (range: 18 to 67 months). Statistically significant differences were observed between the two groups for both PFS and OS (all P<0.001). In the sequential chemotherapy group, the 3-year, 5-year, and 10-year OS rates were 100% (70/70), 93% (65/70), and 21% (15/70), respectively. In contrast, in the conventional chemotherapy group, the OS rates were 50% (15/30) at 3 years, 3% (1/30) at 5 years, and 0 at 10 years, respectively. The two groups were compared respectively, and the differences were statistically significant (all P<0.05). Conclusions:Sequential chemotherapy significantly prolongs PFS and OS in patients with ovarian epithelial carcinoma, fallopian tube carcinoma, and primary peritoneal carcinoma. The efficacy is superior to that of the conventional chemotherapy, with manageable adverse reactions. The use of sequential chemotherapy as first-line treatment for patients with ovarian epithelial carcinoma, fallopian tube carcinoma, and primary peritoneal carcinoma is recommended.
