OBJECTIVE To investigate the mechanism by which esketamine improves postoperative cognitive impairment in rats with hip fracture based on the AMP-activated protein kinase （AMPK）/silencing information regulatory factor 1 （SIRT1）/ peroxisome proliferator activated-receptor-γ coactivator-1α （PGC-1α） signaling pathway. METHODS Rats with hip fracture surgery were assigned into model group， esketamine group （10 mg/kg）， inhibitor group （250 μg/mL AMPK inhibitor Compound C）， and esketamine+inhibitor group （10 mg/kg esketamine + 250 μg/mL Compound C）， and rats undergoing sham surgery were used as the control group， with 12 rats in each group. New object recognition and Barnes maze experiments were used to E-mail：448231@163.com evaluate cognitive function in rats. The levels of serum tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β），superoxide dismutase （SOD）， malondialdehyde （MDA）， gamma-aminobutyric acid （GABA）， dopamine （DA） and glutamate （Glu）， and the apoptosis of hippocampal neurons were detected. The pathological morphology of the hippocampal tissue and the ultrastructure of mitochondria were observed. The mRNA expression of B-cell lymphoma-2 （Bcl-2） and Bcl-2-associated X protein （Bax），the mRNA and protein expression of AMPK， SIRT1 and PGC-1α， as well as the expression of phosphorylated （p）-AMPK in hippocampal tissue， were detected. RESULTS Compared with the control group， the hippocampal neurons in the model group of rats were disordered， with more neurons necrotic and swollen mitochondria；the new object recognition index， the SOD， GABA， DA levels， Bcl-2， AMPK， SIRT1 and PGC-1α mRNA expression levels， and p-AMPK， SIRT1， PGC-1α protein expression levels were significantly reduced， while the latency and number of errors for locating unknown holes， the TNF-α， IL-1β， MDA and Glu levels， neuronal cell apoptosis rate， and Bax mRNA expression levels were significantly increased/prolonged （P＜0.05）. Compared with the model group， the esketamine group showed reduced pathological damage to the hippocampal tissue of rats， and the new object recognition index， the SOD， GABA and DA levels， the Bcl-2， AMPK， SIRT1 and PGC-1α mRNA expression levels， and p-AMPK， SIRT1， PGC-1α protein expression levels were significantly increased，while the latency and error frequency for locating unknown holes， TNF-α， IL-1β， MDA and Glu levels， neuronal cell apoptosis rate， and Bax mRNA expression levels were significantly decreased （P＜0.05）；the inhibitor group showed the opposite trend of changes in these indicators compared to the esketamine group （P＜0.05）.AMPK inhibitor could reverse the improvement effect of esketamine on the above indicators after hip fracture surgery in rats （P＜0.05）. CONCLUSIONS Esketamine may improve postoperative inflammatory response and oxidative stress levels in rats with hip fracture by activating the AMPK/SIRT1/PGC-1α signaling pathway， inhibiting neuronal cell apoptosis， improving mitochondrial structure， and promoting postoperative cognitive function recovery.

The paper introduces Professor ZHUANG Lixing's academic thought on Daoqi Tongjing (directing qi to preserve essence) needling technique and the clinical experience. Based on Huangdi Neijing (the Yellow Emperor's Inner Classic), Dongyuan needling technique and Professor JIN Rui 's Daoqi Tongjing needling method, and by inheriting the valuable experience from the ancient masters and associating with his own clinical practices, Professor ZHUANG Lixing fully displayes the characteristics of principles, methods, formulas, acupoints and techniques of acupuncture in diagnosis and treatment of diseases. He integrates the thought of regulating the mind with Daoqi Tongjing needling. This needling method focuses on directing qi through mind regulation and needle manipulation, in which, the operation steps are refined. Besides, this needling method involves both the reinforcing and reducing techniques. The satisfactory effect of this needling has been obtained in clinical treatment for many disorders such as qi reversion and disharmony of yin and yang.

Pharmacological theory based on natural phenomena(abbreviated as natural-phenomena-based pharmacology)belongs to the traditional theory of Chinese herbal medicine,and is originated from Huang Di Nei Jing(The Yellow Emperor's Inner Classic).By analyzing the correlation of four properties and five flavors of medicines with the seasonal changes of nature,Zhang Yuansu,a famous physician of Yuan Dynasty,put forward the view that medicines'properties accord with the features of climatic factors of nature,showing that wind has the properties of ascending and generating,heat has the properties of going up and growing,dampness has the properties of transforming and developing,dryness has the properties of descending and reaping,and cold has the properties of sinking and storing,and then established the theory of natural-phenomena-based pharmacology.As a promotion of the theory,Li Dongyuan advocated that the medication should adapt to the seasonal changes and to the ascending,descending,floating and sinking of qi movement of human body.By reviewing the viewpoints of Zhang Yuansu and Li Dongyuan on natural-phenomena-based pharmacology,this paper discussed the application of natural-phenomena-based pharmacological theory,such as wind-medicine having the properties of ascending and generating,heat-medicine having the properties of going up and growing,damp-medicine having the properties of transforming and developing,dry-medicine having the properties of descending and reaping,and cold-medicine having the properties of sinking and storing,in the identification and treatment of gynecological diseases.The unique way of classification of Chinese herbal medicines according to the theory of natural-phenomena-based pharmacology reflects the view of correspondence between human being and nature.And medication following the theory of natural-phenomena-based pharmacology accords with the thinking of traditional Chinese medicine(TCM),and is in line with the seasonal changes,which reflects the biological rhythm of the human body.Identification of gynecological diseases from the disorders of qi movement,and medication following the theory of medicinal-feature-based pharmacology for gynecological diseases in TCM will provide a novel approach to homotherapy for heteropathy of gynecological diseases in TCM.

Perimenopausal generalized anxiety disorder belongs to the category of"depression syndrome"in traditional Chinese medicine.It is caused by disharmony of blood vessels,stagnation of qi,and disturbance of the mind and brain,leading to excessive or insufficient qi in the five zang organs.Based on different clinical manifestations,it can be divided into five types of depression.In clinical treatment,Professor Zhuang Lixing applies the mind-regulating acupuncture therapy,with the main acupoints being Sishenzhen,Shenting(GV24),Yintang(EX-HN3),Shenmen(HT7),and Sanyinjiao(SP6).Additional acupoints can be selected according to the patient's symptoms.During the manipulation,the"guiding qi and harmonizing essence"reinforcing and reducing technique is used to regulate emotions and guide qi to relieve depression.This method has shown excellent clinical efficacy and is suitable for clinical promotion.

Glycogen storage disease type Ⅱ,also known as Pompe disease,is an autosomal recessive metabolic myopathy with pulmonary hypertension as a rare complication.We reported a case of pulmonary hypertension in adult with late-onset glycogen storage disease type Ⅱ.Her arterial blood gas results indicated type Ⅱ respiratory failure,lung function indicated severe restricted ventilation dysfunction,sleep monitoring indicated severe sleep apnea hypopnea,severe nocturnal hypoxemia,echocardiography-derived systolic pulmonary pressure was 62 mmHg(1 mmHg=0.133 kPa),electromyography indicated myogenic lesion,and whole exon sequencing indicated GAA gene mutation.Supportive therapy and enzyme replacement therapy are applied in this patient.

Objectives:To observe the effectiveness and safety of recombinant human brain natriuretic peptide(rhBNP)for the treatment of patients with right heart failure caused by pulmonary arterial hypertension(PAH).Methods:A total of 421 patients with right heart failure caused by PAH who were hospitalized in Fuwai Hospital from January 2019 to June 2024 were retrospectively included in this study.All patients were treated with rhBNP on top of conventional therapy.24 h urine volume,body weight,liver and renal function index,electrolyte,uric acid,red blood cell distribution width(RBCDW),cardiac function,blood pressure and heart rate before and after the treatment of rhBNP were compared.Clinical symptoms,signs and the occurrence of adverse events during treatment were also observed.Results:Compared with baseline,after treatment with rhBNP,the 24 h urine volume increased.The levels of body weight,transaminase,total bilirubin,direct bilirubin,uric acid,RBCDW,systolic blood pressure,heart rate,and N-terminal pro-B-type natriuretic peptide significantly decreased(all P<0.05).There were no statistically significant differences in the levels of serum creatinine,and tricuspid annular plane systolic excursion to pulmonary artery systolic pressure ratio(both P>0.05).Dyspnea and lower limbs edema were improved in 75.2%cases(227/302)and 66.9%cases(281/420)respectively.The incidence of adverse events and severe adverse events during rhBNP treatment were 1.2%(5/421)and 0.5%(2/421)respectively.Conclusions:Adding rhBNP on top of standard medication can effectively increase 24 h urine volume,reduce body weight,improve some prognostic indicators,improve the clinical symptoms and signs of heart failure without negatively affecting the renal function in right heart failure patients caused by PAH.Blood pressure should be closely monitored during the treatment process.
