BACKGROUND:The quadriceps strength of patients with osteoporosis and sarcopenia is significantly reduced,which can further reduce the function of the knee joint,affect the function of the lower limbs and even lead to a decrease in whole-body coordination.It is speculated that a reasonable quadriceps training program and personalized guidance are beneficial to the recovery of knee joint function in patients with osteoporosis and sarcopenia.OBJECTIVE:To observe the effect of short-term moderate-intensity resistance rehabilitation training on the mass and function of the quadriceps and knee joint function in patients with osteoporosis and sarcopenia.METHODS:Using the integrated physical examination and rehabilitation model,375 patients with osteoporosis and sarcopenia were screened at the Health Management Center of Shanghai Public Health Clinical Center.They underwent 12 weeks of combined/comprehensive exercise rehabilitation based on resistance exercise,including quadriceps resistance isotonic and isometric contraction training twice a week(3-5 sets each time,10-15 minutes per set)and aerobic exercise/balance exercise two or three times a week(30 minutes each time).Assessments and data collection were performed before rehabilitation training,12 weeks after rehabilitation training,and at follow-up 12 weeks after stopping rehabilitation training,mainly including knee joint range of motion and proprioception,quadriceps muscle strength,and cross-sectional area(magnetic resonance imaging results),pain,knee joint function(Hospital for Special Surgery score)and walking function("up-and-go"time and 6 m pace test results)as well as the patient's psychological status assessment.RESULTS AND CONCLUSION:All 375 patients completed 12 weeks of rehabilitation training and 12 weeks of follow-up without any adverse events.(1)Compared with before training,the patients' gait speed and knee range of motion increased significantly after 12 weeks of rehabilitation training(P<0.01),the time of"stand-to-walk"decreased(P<0.01),and the proprioception of the knee joint and the strength of the quadriceps femoris were significantly improved(P<0.01);and at the follow-up visit 12 weeks after stopping training,the above indicators and functions of the patients were well maintained(P>0.05).(2)Magnetic resonance imaging results showed that the effective cross-sectional area of the quadriceps femoris did not improve significantly after 12 weeks of rehabilitation training(P>0.05);but the Hospital for Special Surgery score of knee joint function increased significantly(P<0.01),and the visual analog pain scale score decreased significantly(P<0.01),suggesting that this may be related to the improvement of quadriceps femoris quality by resistance rehabilitation training.(3)The results of the Hospital Anxiety and Depression Scale score showed that the anxiety and depression scores of the patients continued to decrease,both at 12 weeks of rehabilitation training and at 12 weeks after stopping training(P<0.01).It is suggested that resistance rehabilitation training of the quadriceps can help patients with osteoporosis and sarcopenia to restore quadriceps muscle strength,increase range of motion,improve proprioception and joint stability,thereby enhancing knee joint function,reducing pain,improving depression and anxiety,and to a certain extent promoting the coordinated recovery of the musculoskeletal system.

ObjectiveTo investigate the therapeutic effects and mechanisms of modified Huangqi Jianzhong decoction (HQJZ) on gastric precancerous conditions (GPC). MethodsIn the cell experiment, human gastric mucosal epithelial cells underwent malignant transformation induced by N-methyl-N′-nitro-N-nitrosoguanidine (MNNG) for the modeling of GPC (MC cells). The cells were allocated into four groups: control , model, low-dose HQJZ (HQJZ-L), and high-dose HQJZ (HQJZ-H). The control and model groups were cultured with the complete medium, while HQJZ-L and HQJZ-H groups received additional interventions with HQJZ at low (0.5 g·L-1) and high (1.0 g·L-1) doses, respectively. Cell counting kit-8 (CCK-8) assay was used to evaluate cytotoxicity, Transwell assay to assess cell invasion, Annexin V-FITC/PI staining to detect apoptosis, immunofluorescence assay to analyze reactive oxygen species (ROS) expression and mitochondrial autophagy, and Western blot to verify expression of proteins in key pathways. In the animal experiment, the GPC model was established in healthy BALB/c mice through MNNG induction. Twenty-four mice were allocated into four groups: control, model, HQJZ-L, and HQJZ-H. Control and model groups received normal saline (10 mL·kg-1·d-1) orally, while HQJZ-L and HQJZ-H groups were administrated with low-dose (6.24 g·kg-1·d-1) and high-dose (12.48 g·kg-1·d-1) HQJZ, respectively. After treatment, hematoxylin‑eosin (HE) staining and AB-PAS staining were performed to observe histopathological changes in the gastric tissue. Immunofluorescence assay was used to detect reactive oxygen species (ROS) and microtubule-associated protein 1 light chain 3 (LC3) levels in the gastric mucosa, TdT-mediated dUTP nick-end labeling (TUNEL) staining to assess apoptosis rates, and Western blotting and immunohistochemistry (IHC) to analyze the expression levels of Ki67, proliferating cell nuclear antigen (PCNA), and foxhead box O3 (FoxO3). ResultsCell viability assays showed that HQJZ dose-dependently reduced MC cell viability compared with the control group (P<0.05, P<0.01). Transwell assays revealed that the model group exhibited enhanced cell invasion compared with the control group (P<0.05). Compared with the model group, HQJZ treatment attenuated the cell invasion (P<0.05). Gastric mucosal pathology in mice demonstrated that compared with the control group, the model group showed elevated HE and AB-PAS pathological scores (P<0.05), while HQJZ treatment reduced these scores (P<0.05). Transmission electron microscopy revealed increased mitochondrial number and volume in the model group compared with the control group. HQJZ treatment resulted in abnormal mitochondrial structure and significant alterations in rough endoplasmic reticulum morphology and distribution, presenting as dilated and hollow forms. Mitochondrial and apoptosis assessments indicated that compared with the control group, the model group exhibited enhanced Mito Tracker Green fluorescence (P<0.05), no significant change in DCFH-DA fluorescence, Mito Tracker Red CMXRos fluorescence, ROS immunofluorescence, or malondialdehyde (MDA) level, increased GSH level (P<0.05), enhanced LC3 fluorescence (P<0.05), no significant change in apoptosis rate, and elevated ATP content in cells and mouse serum (P<0.05). Compared with the model group, HQJZ treatment reduced Mito Tracker Green fluorescence (P<0.05), increased DCFH-DA fluorescence, Mito Tracker Red fluorescence, MDA level, LC3 fluorescence, and apoptosis rate (P<0.05), and decreased cellular ATP content (P<0.05). The HQJZ-L group showed no significant change in ROS immunofluorescence or GSH level, whereas the HQJZ-H group demonstrated enhanced ROS immunofluorescence and glutathione (GSH) level (P<0.05). Immunohistochemistry and Western blotting revealed that compared with the control group, the model group exhibited increased numbers of PCNA- and Ki67-positive cells (P<0.05) and elevated protein levels of FoxO3, sirtuin 1 (SIRT1), and B-cell lymphoma 6 (Bcl-6) (P<0.05). HQJZ treatment reduced the numbers of PCNA- and Ki67-positive cells (P<0.05) and lowered the protein levels of FoxO3, SIRT1, and Bcl-6 (P<0.05). ConclusionHQJZ alleviates the progression of gastric precancerous lesions by regulating mitochondrial function via the FoxO3/ROS pathway and promoting apoptosis of GPC-malignant cells.

ObjectiveTo explore the pharmacological mechanism involved in the treatment of allergic cough (AC) by Xiaoer Huatan Zhike granules (XEHT) based on proteomics and network pharmacology. MethodsAfter sensitization by intraperitoneal injection of 1 mL suspension containing 2 mg ovalbumin (OVA) and 100 mg aluminum hydroxide, a guinea pig model of allergic cough was constructed by nebulization with 1% OVA. The modeled guinea pigs were randomized into the model, low-, medium- and high-dose (1, 5, 20 g·kg-1, respectively) XEHT, and sodium montelukast (1 mg·kg-1) groups (n=6), and another 6 guinea pigs were selected as the blank group. The guinea pigs in drug administration groups were administrated with the corresponding drugs by gavage, and those in the blank and model groups received the same volume of normal saline by gavage, 1 time·d-1. After 10 consecutive days of drug administration, the guinea pigs were stimulated by 1% OVA nebulization, and the coughs were observed. The pathological changes in the lung tissue were observed by hematoxylin-eosin staining. The enzyme-linked immunosorbent assay was performed to measure the levels of C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), superoxide dismutase (SOD), and malondialdehyde (MDA) in the bronchoalveolar lavage fluid (BALF) and immunoglobulin G (IgG) and immunoglobulin A (IgA) in the serum. Immunohistochemistry (IHC) was employed to observe the expression of IL-6 and TNF-α in the lung tissue. Transmission electron microscopy was employed observe the alveolar type Ⅱ epithelial cell ultrastructure. Real-time PCR was employed to determine the mRNA levels of IL-6, interleukin-1β (IL-1β), and TNF-α in the lung tissue. Label-free proteomics was used to detect the differential proteins among groups. Network pharmacology was used to predict the targets of XEHT in treating AC. The Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis was performed to search for the same pathways from the results of proteomics and network pharmacology. ResultsCompared with the blank group, the model group showed increased coughs (P<0.01), elevated levels of CRP, TNF-α, IL-6, and MDA and lowered level of SOD in the BALF (P<0.05, P<0.01), elevated levels of IgA and IgG in the serum (P<0.05, P<0.01), congestion of the lung tissue and infiltration of inflammatory cells, increased expression of IL-6 and TNF-α (P<0.01), large areas of low electron density edema in type Ⅱ epithelial cells, obvious swelling and vacuolization of the organelles, karyopyknosis or sparse and dissolved chromatin, and up-regulated mRNA levels of IL-6, IL-1β, and TNF-α (P<0.01). Compared with the model group, the drug administration groups showed reduced coughs (P<0.01), lowered levels of CRP, TNF-α, IL-6, and MDA and elevated level of SOD in the BALF (P<0.05, P<0.01), alleviated lung tissue congestion, inflammatory cell infiltration, and type Ⅱ epithelial cell injury, and decreased expression of IL-6 and TNF-α (P<0.01). In addition, the medium-dose XEHT group and the montelukast sodium group showcased lowered serum levels of IgA and IgG (P<0.05, P<0.01). The medium- and high-dose XEHT groups and the montelukast sodium showed down-regulated mRNA levels of IL-6, IL-1β, and TNF-α and the low-dose XEHT group showed down-regulated mRNA levels of IL-6 and TNF-α (P<0.05, P<0.01). Phospholipase D, mammalian target of rapamycin (mTOR), and epidermal growth factor receptor family of receptor tyrosine kinase (ErbB) signaling pathways were the common pathways predicted by both proteomics and network pharmacology. ConclusionProteomics combined with network pharmacology reveal that XEHT can ameliorate AC by regulating the phospholipase D, mTOR, and ErbB signaling pathways.

Lipid turbidity disease is a metabolic disease featuring lipid metabolism disorders caused by many factors such as social environment, diet, and lifestyle, which is closely related to many diseases in modern medicine, such as hyperlipidemia, obesity, fatty liver, atherosclerosis, metabolic syndrome, and cardiovascular and cerebrovascular diseases, with a wide range of influence and far-reaching harm. According to the Huangdi Neijing, lipid turbidity disease reflects the pathological change of the body's physiologic grease. Grease is the thick part of body fluids, which has the function of nourishing, and it is the initial state and source of important substances in the human body such as brain, marrow, essence, and blood. Once the grease of the human body is abnormal, it can lead to lipid turbidity disease. The Huangdi Neijing also points out the physiological relationship between the transportation and transformation of body fluids and the rise and fall of the spleen and stomach, which can deduce the pathological relationship between the occurrence of lipid turbidity disease and the abnormal rise and fall of the spleen and stomach functions. Lipid turbidity disease is caused by overconsumption of fatty and sweet foods or insufficient spleen and stomach endowments, leading to disorders of the function of promoting clear and reducing turbidity in the spleen and stomach. This leads to the transformation of thick grease in body fluids into lipid turbidity, which accumulates in the body's meridians, blood vessels, skin pores, and organs, forming various forms of metabolic diseases. The research team believed that the pathological basis of lipid turbidity disease was the abnormal rise and fall of the spleen and stomach and the obstruction of the transfer of grease. According to the different locations where lipid turbidity stays, it was divided into four common pathogenesis types: ''inability to distinguish between the clear and turbid, turbid stagnation in the Ying blood'', ''spleen not rising clear, turbid accumulation in the vessels'', ''spleen dysfunction, lipid retention in the pores'', ''spleen failure to transportation and transformation, and grease accumulation in the liver''. According to the pathogenesis, it could be divided into four common syndromes, namely, turbid stagnation in the Ying blood, turbid accumulation in the vessels, lipid retention in the pores, and grease accumulation in the liver, and the corresponding prescriptions were given for syndrome differentiation and treatment, so as to guide clinical differentiation and treatment of the lipid turbidity disease.

Objective:To assess the impact of induction chemotherapy sensitivity on the prognosis and larynx preservation rates in patients with locally advanced hypopharyngeal cancer and to identify risk factors influencing induction chemotherapy sensitivity.Methods:This study included patients with locally advanced (stage III-IV) hypopharyngeal cancer who received induction chemotherapy as initial treatment at the Eye & ENT Hospital of Fudan University between August 2017 and September 2022. Based on the Response Evaluation Criteria in Solid Tumors (RECIST) 1.1, enrolled patients were classified into the sensitive group and the resistant group according to their response to induction chemotherapy. Chi-square tests and Log-rank tests were used to compare the objective response rate (ORR), overall survival (OS), progression-free survival (PFS), and laryngeal preservation rate (LPR) between groups. Propensity score matching (PSM) was employed to accurately evaluate the impact of induction chemotherapy sensitivity on prognosis in real-world settings. Univariate and multivariate logistic regression analyses were performed to identify risk factors for induction chemotherapy resistance in locally advanced hypopharyngeal cancer.Results:A total of 197 patients with locally advanced hypopharyngeal cancer who received induction chemotherapy as initial treatment were included in, comprising 195 males and 2 females, with ages ranging from 36 to 74 years. Among them, 155 patients (78.68%) were classified into the sensitive group and 42 patients (21.32%) into the resistant group. The overall response rate (ORR) of induction chemotherapy in this cohort was 78.68%, with a five-year OS rate of 63.7%. The sensitive group had significantly better OS (mOS 6.32 vs. 5.05 year), PFS (mPFS 5.71 vs. 3.09 year) and a significantly higher LPR (91.6% vs. 69.0%) ( P<0.05). After propensity score matching, all covariates were balanced between the two groups, and the sensitive group showed significant improvement in OS ( P<0.05), while, no significant difference was observed in PFS and LPR between the two groups. Logistic regression analysis revealed that risk factors for induction chemotherapy failure in locally advanced hypopharyngeal cancer included: smoking status ( OR [95% CI]=4.751 [1.887-11.961]), tumor location in the posterior pharyngeal wall ( OR [95% CI]=2.988 [1.264-7.063]), and cN2-3 stage ( OR [95% CI]=3.641 [1.109-11.954]) ( P<0.05). Conclusions:Induction chemotherapy sensitivity significantly affects the prognosis of locally advanced hypopharyngeal cancer, which is influenced by various risk factors, including smoking status, tumor sublocation, and clinical N stage.

Objective:To investigate the feasibility and effect of endoscopic assisted surgery combined with sclerosing agent injection and negative pressure drainage for the treatment of microcystic lymphatic malformation in children.Methods:A retrospective analysis was conducted on clinical data of pediatric patients with microcystic lymphatic malformations between December 2021 and December 2023 in the Department of Burns and Plastic Surgery at Children’s Hospital of Nanjing Medical University. The treatment protocol consisted of endoscope-assisted surgery combined with sclerotherapy and negative pressure drainage. Preoperatively, two-dimensional ultrasound was utilized to demarcate the surface extent of the malformation. Intraoperatively, subcutaneous lymphatic malformation tissues were resected as thoroughly as possible under endoscopic guidance, and cystic cavities were interconnected. Postoperatively, a drainage tube was placed and connected to a negative pressure system. Starting on the third postoperative day, the cystic cavity was irrigated with absolute ethanol every other day. Irrigation was continued until the drainage fluid became light yellow and clear, and the daily drainage volume fell below 5 ml, at which point the drainage tube was removed. Complications were monitored, and treatment efficacy was assessed at the last follow-up using a four-tiered outcome scale: cured, markedly effective, effective, and ineffective. The overall effectiveness rate was calculated as (cured + markedly effective + effective) cases/total number of cases × 100%. Data analysis was performed using descriptive statistics.Results:A total of 20 pediatric patients were enrolled, including 8 males and 12 females. The age range was from 1 month to 13 years, with a mean age of 7 years and 7 months. All lesions were located superficially, distributed as follows: head, face, and neck (8 cases), chest (2 cases), abdomen (3 cases), back (2 cases), and limbs (5 cases). The lesion volumes ranged from 5.8 cm × 4.2 cm × 3.8 cm to 14.5 cm × 10.4 cm × 8.4 cm. No complications such as absolute ethanol intoxication, severe allergic reactions, surgical site infection, neurovascular injury, thrombosis, or pulmonary embolism occurred during the treatment period. All patients had their negative pressure drainage tubes removed on postoperative day 10. After tube removal, one case developed serous drainage from the incision, which resolved after 4 days of wound care and compressive dressing. The remaining 19 cases demonstrated satisfactory incision healing. During a follow-up period of 6 to 12 months, no significant postoperative scarring and recurrence were observed. Treatment outcomes were as follows: 4 cases of cured, 10 cases of markedly effective, 5 cases of effective, and 1 case of ineffective. The overall effective rate was 95%(19/20).Conclusion:The integrated approach of endoscope-assisted surgery combined with sclerotherapy and negative pressure drainage for the treatment of microcystic lymphatic malformations in children yields definite and favorable outcomes. This comprehensive technique is characterized by its minimal invasiveness, stable long-term result as confirmed by follow-up, absence of severe complications, and a low recurrence rate.
