Laparoscopic subtotal cholecystectomy (LSC) has been a safe and viable alternative to conversion to laparotomy in cases of severe cholecystitis. The objective of this study is to determine the utility of intraoperative choledochoscopy in LSC for the exploration of the gallbladder, cyst duct, and subsequent stone clearance of the cystic duct in cases of severe cholecystitis. A total of 72 patients diagnosed with severe cholecystitis received choledochoscopy-assisted laparoscopic subtotal cholecystectomy (CALSC). A choledochoscopy was performed to explore the gallbladder cavity and/or cystic duct, and to extract stones using a range of techniques. The clinical records, including the operative records and outcomes, were subjected to analysis. No LSC was converted to open surgery, and no bile duct or vascular injuries were sustained. All stones within the cystic duct were removed by a combination of techniques, including high-frequency needle knife electrotomy, basket, and electrohydraulic lithotripsy. A follow-up examination revealed the absence of residual bile duct stones, with the exception of one common bile duct stone, which was extracted via endoscopic retrograde cholangiopancreatography. In certain special cases, CALSC may prove to be an efficacious treatment for the management of severe cholecystitis. This technique allows for optimal comprehension of the situation within the gallbladder cavity and cystic duct, facilitating the removal of stones from the cystic duct and reducing the residue of the non-functional gallbladder remnant.

This paper summarizes the clinical experience in applying jiao （角） medicine to treat diabetes mellitus from the perspective of qi， blood， and fluids. It is believed that impaired spleen transportation and transformation is the key pathomechanism of diabetes， leading to metabolic disturbances in qi， blood， and fluids， and resulting in a sequential pathological progression of "qi → thick fluids → thin fluids → blood". At the qi level， the disease is mainly characterized by spleen qi deficiency and stagnation， and is commonly treated with Hongshen （Panax Ginseng）， Huangqi （Astragalus Mongholicus）， and Baizhu （Atractylodes Macrocephala） to tonify the spleen and regulate qi. At the thick fluids level， the condition manifests as abdominal distension， internal heat， and turbid pathogens， requiring Zexie （Alisma Orientale）， Huanglian （Coptis Chinensis）， and Dahuang （Rheum Palmatum） to clear the spleen and drain turbidity. At the thin fluids level， with qi and yin deficiency and predominant yin damage， Gegen （Pueraria Lobata）， Wuweizi （Schisandra Chinensis）， and Maidong （Ophiopogon Japonicus） are used to nourish yin and generate fluids. At the blood level， where vascular damage is predominant， Shuizhifen （Whitmania Pigra Powder）， Danshen （Salvia Miltiorrhiza）， and Sanqifen （Panax Notoginseng Powder） are applied to activate blood circulation， resolve stasis， and unblock the channels. Clinicians may flexibly select appropriate jiao medicine based on the specific pathological layer affected in each patient.

Kounis syndrome is an acute coronary syndrome triggered by an allergic reaction, which is clinically rare and frequently subject to misdiagnosis or missed diagnosis. This article presents a case report of a 70-year-old male patient who developed a rash, pruritus, and chest pain following colon polyp resection. Coronary angiography revealed occlusion of the left anterior descending artery, and blood flow was restored after stent implantation. However, the patient experienced recurrent symptoms accompanied by loss of consciousness. Drug skin tests confirmed positive reactions to chlorhexidine and fondaparinux sodium, leading to a diagnosis of type Ⅱ Kounis syndrome. By avoiding allergenic drugs and combining antihistamines with symptomatic treatment to correct myocardial ischemia, the patient′s clinical symptoms significantly improved, and he eventually recovered and was discharged from the hospital. This case underscores the importance of maintaining vigilance for this syndrome in patients with allergies accompanied by chest pain and promptly identifying and avoiding allergens.

ObjectiveBased on the experience of traditional quality evaluation， the quality of Atractylodis Macrocephalae Rhizoma（AMR） with different production methods such as direct seeding， transplanting after seedling raising， topping and non-topping， and difference in growth years was compared. MethodVernier caliper was used to measure the trait data of AMR in different production methods. Paraffin sections of AMR with different production methods were made by saffron solid green staining， and the microstructure was observed. The contents of water-soluble and alcohol-soluble extracts in AMR with different production methods were determined according to the 2020 edition of Chinese Pharmacopoeia. The content of water-soluble total polysaccharides in AMR with different production methods was detected by sulfuric acid-anthrone method. Fiber analyzer was used to detect the content of fiber components in AMR with different production methods. The contents of monosaccharides， oligosaccharides and some secondary metabolites in AMR with different production methods were detected by ultra performance liquid chromatography（UPLC）， and the differences of chemical components were compared by multivariate statistical analysis methods such as principal component analysis（PCA） and partial least squares-discriminant analysis（PLS-DA）. ResultIn terms of traits， the 3-year-old AMR with direct seeding and without topping was close to the high-quality AMR with "phoenix-head and crane-neck， strong sweetness and clear aroma" recorded in ancient materia medica， followed by the 3-year-old AMR with topping after transplanting， while the 2-year-old AMR with topping after transplanting with high market circulation rate was generally fat and strong with mild odor. In the microscopic aspect， the arrangement of xylem vessels and fiber bundles in the 3-year-old samples formed two obvious rings. Compared with the 2-year-old samples cultivated in Bozhou and Zhejiang， the 3-year-old samples without topping after transplanting had more wood fibers. In terms of chemical composition， the contents of 70% ethanol extract， fructose， glucose， sucrose， 1-kestose， atractylenolide Ⅰ， chlorogenic acid， neochlorogenic acid， cryptochlorogenic acid and other components in 3-year-old AMR with direct seeding and without topping were significantly higher than those in the other three samples（P<0.05）. The contents of cellulose， 70% ethanol extract， sucrose， atractylenolide Ⅰ， atractylone and other components in 3-year-old AMR with topping after transplanting were significantly higher than those in the 2-year-old AMR with high market circulation rate（P<0.05）， while the contents of water-soluble extract and water-soluble total polysaccharides in 2-year-old samples with topping after transplanting were significantly higher than those in the 3-year-old AMR with topping after transplanting， direct seeding and without topping（P<0.05）. ConclusionUnder the current mainstream production mode， too much manual intervention makes AMR heavily enriched in polysaccharides and increased the yield， but the accumulation of sweet substances， fragrant substances and fiber substances is insufficient， which affects its quality. The current quality standard of AMR has some shortcomings in guiding the high quality production of it， it is suggested to revise the quality standard of AMR， supplement the quantitative analysis of secondary metabolites， and strengthen the production of imitation wild AMR.

Objective To explore the risk factors for the occurrence of hypertension in middle-aged and elderly residents in China using the Cox regression analysis model and decision tree model, and compare the differences between the two methods. Methods The 2011-2015 China Health and Retirement Longitudinal Study data were used. The study investigated the risk factors for hypertension using both a multivariate Cox regression model and a decision tree model. Results The results showed that the incidence rate of hypertension between 2011-2015 was 22.79%. Both the Cox regression model and decision tree model identified age, education level, body mass index, and diabetes as risk factors for hypertension. The Cox regression model also identified drinking status as a risk factor, while the decision tree model identified gender and marital status as additional risk factors. The area under the curve (AUC) suggested that the Cox regression model and decision tree model had comparable ability to predict hypertension. Conclusions The risk factors for hypertension include gender, age, education level, marital status, alcohol consumption, body mass index, and history of diabetes. The effectiveness of the hypertension prediction model established based on Cox regression model and decision tree model results is not different.

Objective:To establish the rat cardiac arrest model in high-altitude hypobaric hypoxia environment, and to explore the effect of the treatment time in the hypobaric oxygen chamber on the reproduction of high-altitude rat cardiac arrest model.Methods:SPF grade healthy male Sprague-Dawley (SD) rats were used as observation subjects. The experiment was conducted in two different altitude areas. The rats from the Plateau Branch of Institute of Cardiopulmonary and Cerebral Resuscitation of Sun Yat-sen University (Xining, Qinghai) were weighed and numbered, and they were placed in a hypobaric oxygen chamber (simulated altitude of 3 000 meters, speed of ascent and descent of 15 m/min, temperature of 20 ℃, cabin pressure of 69.5 kPa, cabin oxygen pressure of 14.5 kPa). After 30 days of feeding, the rats were obtained according to random number table method, and the cardiac arrest model was established by asphyxia method as the 30-day hypobaric hypoxia group. After 60 days of feeding, rats were randomly selected again, and the cardiac arrest model was established as the 60-day hypobaric hypoxia group. Thirty rats were randomly selected from the Institute of Cardiopulmonary Cerebral Resuscitation at Sun Yat-sen University (Guangzhou, Guangdong) by the same method, and the cardiac arrest model was established as the plain control group. The differences in the body weight of rat modeling precursors and the induction time of asphyxia during the modeling process among different groups were compared.Results:Finally, cardiac arrest model was established in 16 rats in the 30-day hypobaric hypoxia group and in 22 rats in the 60-day hypobaric hypoxia group. There was no significant difference in the body weight of rats before modeling among the plain control group, 30-day hypobaric hypoxia group and 60-day hypobaric hypoxia group [g: 429.00 (389.25, 440.75), 440.00 (415.50, 486.25), 440.00 (400.00, 452.50), all P > 0.05]. The asphyxia induction time of rats in the 60-day hypobaric hypoxia group was significantly longer than that in the 30-day hypobaric hypoxia group (s: 294.59±75.39 vs. 234.31±93.86, P < 0.01), even about 1.4 times of the plain control group (s: 294.59±75.39 vs. 208.73±30.88, P < 0.01). There was no significant difference in the asphyxia induction time between the 30-day hypobaric hypoxia group and the plain control group ( P > 0.05). Conclusion:Rats treated in a hypobaric oxygen chamber for 60 days are more suitable for the preparation of high-altitude cardiac arrest model, and are also consistent with the oxygen reserve and hypoxia tolerance of high-altitude rats.

Objective To investigate the relationship between interleukin-1β (IL-1β) and miR-185-5p in the process of joint injury in acute gouty arthritis (AGA). Methods The serum miR-185-5p levels of 89 AGA patients and 91 healthy volunteers were detected by real-time quantitative PCR. The correlation between miR-185-5p expression level and VAS score or IL-1β expression level was evaluated by Pearson correlation coefficient method. Receiver operating characteristic (ROC) curve was used to evaluate the diagnostic value of miR-185-5p in AGA. THP-1 cells were induced by sodium urate (MSU) to construct an in vitro acute gouty inflammatory cell model. After the expression level of miR-185-5p in THP-1 cells was upregulated or downregulated by transfection of miR-185-5p mimics or inhibitors in vitro, inflammatory cytokines of THP-1 cells, such as IL-1β, IL-8 and tumor necrosis factor α (TNF-α), were detected by ELISA. The luciferase reporter gene assay was used to determine the interaction between miR-185-5p and the 3'-UTR of IL-1β. Results Compared with the healthy control group, the expression level of serum miR-185-5p in AGA patients was significantly reduced. The level of serum miR-185-5p was negatively correlated with VAS score and IL-1β expression level. The area under the curve (AUC) was 0.905, the sensitivity was 80.17% and the specificity was 83.52%. Down-regulation of miR-185-5p significantly promoted the expression of IL-1β, IL-8 and tumor necrosis factor (TNF-α), while overexpression of miR-185-5p showed the opposite results. Luciferase reporter gene assay showed that IL-1β was the target gene of miR-185-5p, and miR-185-5p negatively regulated the expression of IL-1β. Conclusion miR-185-5p alleviates the inflammatory response in AGA by inhibiting IL-1β.

Alzheimer’s disease (AD), characterized by cognitive decline and neurodegeneration, currently relies on pharmacological treatments that are limited in efficacy and often accompanied by side effects. As the number of AD patients increases, so does the economic burden on both the global healthcare system and families of patients, further worsening the quality of life for patients in their later years. Therefore, it is crucial to find new and more effective therapeutic approaches. This necessity has sparked a growing interest in non-invasive therapies, such as 40 Hz rhythmic stimulation, which aims to modulate brain activity to potentially reverse pathological changes and alleviate symptoms. This review provides an overview of the effects of 40 Hz stimulation on AD pathology and symptoms, its impact on cognitive functions in healthy individuals, the underlying mechanisms of action, and strategies to enhance the treatment’s compliance and effectiveness. Research has demonstrated that 40 Hz rhythmic stimulation, particularly through auditory and visual modalities, can influence core AD pathologies. In mouse models of AD, this stimulation has been shown to reduce amyloid-beta protein (Aβ) plaques and phosphorylated tau protein levels, hallmarks of AD pathology. These effects are thought to stem from enhanced waste clearance mechanisms, facilitated by the stimulation of the glymphatic system and the activation of microglia. Clinical applications in AD patients have shown promising results, with improvements noted in cognitive functions and behavioral symptoms. These findings suggest that 40 Hz rhythmic stimulation could offer a non-pharmacological option to mitigate the pathological progression and symptomatic expression of AD. In healthy individuals, the cognitive outcomes of 40 Hz stimulation appear more variable. Some studies indicate potential enhancements in memory and attention, proposing that 40 Hz stimulation may bolster cognitive resilience and processing efficiency in a non-diseased brain. However, these effects are not consistently replicated across studies, indicating that individual differences and specific stimulation parameters may significantly influence outcomes. The beneficial effects of 40 Hz rhythmic stimulation are believed to be primarily due to neural entrainment, where neural circuits synchronize their activity to the external frequency. This entrainment may restore the balance between excitatory and inhibitory neural activity, which is often disrupted in AD mice and AD patients. By reinforcing natural brain rhythms, 40 Hz stimulation may enhance neural connectivity and function, facilitating cognitive and memory processes that are deteriorated in AD. Neural entrainment at 40 Hz has been demonstrated to aid in restoring neural network function, enhancing the glymphatic system, improving cerebral blood flow, and providing neuroprotection. These mechanisms are thought to work synergistically to regulate brain activity, potentially leading to a reduction in lesions and an improvement in cognitive performance. To optimize the therapeutic benefits of 40 Hz stimulation, several factors need to be considered. Treatment protocols should be tailored to individual needs, accounting for variability in disease progression and personal health status. Enhancing patient compliance involves simplifying treatment regimens and using portable, user-friendly devices that can be easily incorporated into daily routines. Ongoing research should focus on refining stimulation parameters and delivery methods to maximize efficacy and minimize potential side effects. In conclusion, while 40 Hz rhythmic stimulation represents a promising avenue for treating AD and enhancing cognitive functions, further research is required to fully elucidate its mechanisms, refine its application, and ensure its practicality and efficacy in broad clinical and everyday settings.
