Alzheimer's disease(AD)is a multi-cause neurodegenerative disease characterized by memory impairment.There have been serious obstacles to the effective treatment of AD.Acupuncture,as a component of traditional Chinese medicine,plays an important role in the treatment of AD.Acupuncture has been shown to protect neurons from degeneration and promotes axonal regeneration in neurodegenerative diseases such as AD.According to existing studies,the mechanisms of acupuncture on AD include the following aspects:modulation of Aβ metabolism,tau phosphorylation,cholinergic neurotransmitters,neuroinflammation,synaptic and neuronal function,autophagy,brain glucose metabolism,intestinal flora,and inhibition of nerve cell apoptosis,which in turn improves cognition.

Transcatheter tricuspid valve replacement(TTVR)is characterized by minimal invasiveness,rapid recovery,and a significantly lower perioperative mortality rate compared to surgical procedures.It is the preferred treatment for patients with bioprosthetic valve failure following surgical tricuspid valve replacement.However,when the delivery system is relatively bulky,challenges can arise due to the reduced orifice area post-surgery and the constraints imposed by the valve frame.These factors may result in difficulties advancing the delivery system.Additionally,the tortuous right heart pathway and limited support provided by the guide wire further increase the complexity of the procedure.In the present case,the patient experienced bioprosthetic valve failure following surgical tricuspid valve replacement.During TTVR,the advancement of the delivery system across the tricuspid valve encountered difficulties.Our team promptly employed the parallel anchoring-supporting sheath and snared wire(PASS)technique,pioneered at our center.Utilizing a large supporting sheath in conjunction with a snare to secure the tip of a extra-stiff guide wire,we straightened the tortuous pathway,providing additional support to the extra-stiff guide wire.This maneuver successfully facilitated the advancement of the delivery system across the tricuspid valve,offering a practical and effective solution for overcoming intraoperative challenges associated with TTVR.

Objective:To investigate the risk factors of depression in patients with lacunar cerebral infarction 3 months after discharge, and build a risk prediction model.Methods:The clinical data of 237 patients with lacunar cerebral infarction diagnosed and treated in the Second Affiliated Hospital of Wannan Medical College from January 1, 2021 to January 1, 2022 were retrospectively analyzed. Demographic data, laboratory indicators and risk factors of cardiovascular disease were collected when the patients were admitted to hospital. The patient health questionnaire-9 (PHQ-9) score was used to assess the risk of post-stroke depression (PSD) 3 months after discharge. Univariate and multivariate logistic regression analyses were used to identify independent risk factors of depression. A predictive model was constructed based on the above risk factors. The predictive efficacy was evaluated by receiver operating characteristic (ROC) curve, and the clinical applicability of the predictive model was measured by calibration curve and decision curve.Results:Fifty-four patients with lacunar infarction (22.80%) showed symptoms of depression at 3 months after discharge. Multivariate logistic regression showed that women ( OR=2.952, 95% CI: 1.403-6.213, P=0.004), cystatin C ( OR=2.964, 95% CI: 1.222-7.191, P=0.016), apolipoprotein B ( OR=4.836, 95% CI: 1.533-15.258, P=0.007) were the independent risk factors for PSD in patients with lacunar infarction. Activity of daily living (ADL) score ( OR=0.939, 95% CI: 0.915-0.964, P<0.001) was a protective factor for PSD in patients with lacunar infarction. The area under the curve (AUC) of the prediction model was 0.779 (95% CI: 0.703-0.855, P<0.001), which was better than other predictors. Hosmer-Lemeshow H test showed that the model was well calibrated ( P=0.588). In addition, the prediction model of decision curve analysis had a good clinical applicability. Conclusions:The predictive model based on gender, laboratory indicators and daily life ability score can evaluate the risk of PSD in patients with lacunar infarction 3 months after discharge. It is good predictive efficacy and clinical applicability which worth clinical promotion and application.

The purpose of this study was to investigate the epidemiological characteristics and risk factors of influenza in Hainan province,to provide evidence to support influenza prevention and control efforts.Pathogen monitoring data of influenza-like illness(ILI)in six national sentinel hospitals in Hainan province from 2013 to 2021 were analyzed in SPSS 20.0 software.A total of 50 415 ILI cases were detected during the 2013-2021 season,of which 5 581 were positive for influenza viruses,with a positivity rate of 11.07％.The dominant strains were type B,type A(H1N1)pdm09 and type A(H3N2).The positivi-ty rate of influenza virus was highest in people 5-14 years of age(17.56％)and lowest in people 0-4 years of age(7.32％).Influenza activity showed both a summer peak and a winter-spring peak in the 2014-2016,2017-2018 and 2019-2020 sea-sons,and was concentrated in April to September,with a maximum peak of 53.64％,and in November to March of the next year,with a peak of 47.30％.The 2013-2014,2016-2017 and 2018-2019 seasons showed only a winter-spring peak concen-trated between October and March of the next year,with a maximum peak of 54.17％,but no obvious summer peak.The pre-dominant influenza viruses during the eight surveillance seasons varied among H1N1,H3N2 and type B.The positive detection rate of influenza virus steeply declined during the 2020-2021 season:the positive detection rate was only 0.25％,and no obvi-ous epidemic period was observed.The intensity of influenza epidemic varied among monitoring years,and the dominant strains changed rapidly in Hainan Province.People 5-14 years of age were the key population affected.Summer,winter and spring were the key periods for influenza prevention and control.Etiological surveillance of influenza should continue to be strength-ened,the roles of health education and publicity should be emphasized,and the dual measures of influenza vaccination and non-drug intervention should be actively promoted to decrease the occurrence of influenza.

Under the situation of the rapid expansion of hospital, the dilemma of acupuncture-moxibustion department, as well as the relevant solutions are explored. The main reasons for the shrinking situation of the service in acupuncture-moxibustion department include: the disease-based department division trends to divert many diseases suitably treated in acupuncture-moxibustion department; the environment pursuing economic benefits restricts the development of acupuncture-moxibustion therapy characterized by "simple and low-cost operation". There are three important approaches for breaking through the dilemma of acupuncture and moxibustion therapy. First, modifying the traditional service mode as waiting for patients in acupuncture-moxibustion department and promoting acupuncture and moxibustion technology to be adopted in other departments rather than limited only in acupuncture-moxibustion department. Second, increasing the charges of acupuncture and moxibustion technology rationally. Third, positioning accurately the role of acupuncture and moxibustion technology in health services based on its own characteristics and advantages and promoting it in community medical institutions. All of these solutions require the guidance of supporting policies.

OBJECTIVE: To observe the effect of wheat-grain moxibustion at "Dazhui" (GV 14) on the expressions of Beclin-1 and GRP78 in spinal dorsal horn in rats with cervical spondylotic radiculopathy (CSR), and to explore the possible analgesic mechanism of wheat-grain moxibustion for CSR. METHODS: A total of 48 SD rats were randomly divided into a sham operation group, a model group, a wheat-grain moxibustion group and a wheat-grain moxibustion+3-MA group, 12 rats in each group. The CSR model was prepared by spinal cord insertion method. Three days after modeling, the rats in the model group were intraperitoneally injected with 1 mL of 0.9% sodium chloride solution; the rats in the wheat-grain moxibustion group were treated with wheat-grain moxibustion at "Dazhui" (GV 14, 6 cones per time) on the basis of the model group; the rats in the wheat-grain moxibustion+3-MA group were intraperitoneally injected with 3-MA solution and wheat-grain moxibustion at "Dazhui" (GV 14, 6 cones per time). The three groups were intervened for 7 days, once a day. The gait score and mechanical pain threshold were observed before treatment and 7 days into treatment; after the treatment, the expressions of mRNA and protein of Beclin-1 in spinal dorsal horn were detected by real-time fluorescence quantitative PCR and immunohistochemistry; the expression of GRP78 protein in spinal dorsal horn was detected by Western blot method; the autophagosomes and ultrastructure in spinal dorsal horn neurons were observed by electron microscope. RESULTS: After the treatment, compared with the sham operation group, in the model group, the gait score was increased and the mechanical pain threshold was decreased (P<0.01), and the expression of GRP78 protein in spinal dorsal horn was increased (P<0.01). Compared with the model group and the wheat-grain moxibustion+3-MA group, in the wheat-grain moxibustion group, the gait score was decreased and mechanical pain threshold was increased (P<0.01), and the expression of GRP78 protein in spinal dorsal horn was decreased, and the expressions of mRNA and protein of Beclin-1 were increased (P<0.01). Under electron microscope, the ultrastructure of spinal dorsal horn neurons in the wheat-grain moxibustion group was not significantly damaged, and its structure was basically close to normal, and the number of autophagosomes was more than the other three groups. CONCLUSION Wheat-grain moxibustion at "Dazhui" (GV 14) has analgesic effect on CSR rats. The mechanism may be related to moderately up-regulate the expression of Beclin-1, enhance autophagy and reduce endoplasmic reticulum stress.

OBJECTIVE: To assess the clinical efficacy of minimally invasive technology with trajectory screw fixation for fragility fractures of pelvic(FFP). METHODS: A retrospective case control study was performed to analyze the clinical data of 35 patients with FFP who were treated and followed up between January 2016 and December 2019. There were 12 males and 23 females, aged from 65 to 99 years with an average of(75.4±7.8) years old. There were 13 cases of type Ⅱb, 7 cases of type Ⅱc, 8 cases of type Ⅲa, 2 cases of type Ⅲb, 2 cases of type Ⅲc, 1 case of type Ⅳb, and 2 cases of type Ⅳc according to Rommens FFP comprehensive classification. All patients received the treatment of minimally invasive technology with trajectory screws fixation. According to the different methods of anterior pelvic ring fixation, FFP patients were divided into two groups:12 cases were fixed with the pedicle screw rod system in the anterior pelvic subcutaneous internal fixator (INFIX) group;23 cases were fixed with hollow screws of the pubic symphysis, superior ramus of pubis or acetabular anterior column in the screw group. The operation time, intraoperative blood loss, intraoperative fluoroscopy times, length of hospital stay, cost of internal fixation, pre- and post-operative visual analogue scale(VAS) were compared between the two groups. The fracture reduction quality was evaluated according to the Matta criteria, and the clinical function was evaluated by the Majeed functional scoring system respectively. RESULTS: All patients were followed up for 12 to 39(16.5±5.4) months after surgery. There was no statistically significant difference in the operation time, intraoperative blood loss, intraoperative fluoroscopy time, and length of hospital stay between the two groups(P>0.05). As for the cost of internal fixation, the cost of internal fixation in the screw group [2 914 (2 914, 4 371) yuan] was significantly lower than that of the INFIX group [6 205 (6 205, 6 205) yuan] (P<0.05). No significant difference was observed in the incidence of postoperative complications between the two groups (P>0.05). There was no significant difference in VAS assessment at admission, 1 week, and 3 months after surgery between the two groups(P>0.05). However, the VAS assessment at 1 week and 3 months after surgery of the two groups were significantly better than those at admission(P<0.05). There was no significant difference in the quality of fracture reduction after the operation and the efficacy evaluation at the last follow-up between the two groups(P>0.05). CONCLUSION For the treatment of fragility fractures, minimally invasive technology with trajectory screw fixation can achieve good clinical efficacy. It has the advantages of being relatively minimally invasive, less bleeding, relieving the pain. It deserves clinical application.

Objective:To investigate the knowledge, attitudes, and practices (KAP) of pulse oximetry among pediatric healthcare providers in China and analyze the factor influencing the KAP.Methods:A self-developed questionnaire was used for an online research on the KAP of 11 849 pediatric healthcare providers from 31 provinces, autonomous regions, and municipalities of China from March 11 to 14, 2022.The factors influencing the KAP of pulse oximetry among pediatric healthcare providers were examined by Logistic regression. Results:The scores of KAP, of pulse oximetry were 5.57±0.96, 11.24±1.25 and 11.19±4.54, respectively.The corresponding scoring rates were 69.61%, 74.95%, and 55.99%, respectively. Logistic regression results showed that the gender and working years of pediatric healthcare providers, the region they were located, and whether their medical institution was equipped with pulse oximeters were the main factors affecting the knowledge score (all P<0.05). Main factors influencing the attitude score of pediatric healthcare providers included their knowledge score, gender, educational background, working years, region, medical institution level, and whether the medical institution was equipped with pulse oximeters (all P<0.05). For the practice score, the main influencing factors were the knowledge score, gender, age, and whether the medi-cal institution was equipped with pulse oximeters (all P<0.05). Conclusions:Chinese pediatric healthcare providers need to further improve their knowledge about and attitudes towards pulse oximetry.Pulse oximeters are evidently under-used.It is urgent to formulate policies or guidelines, strengthen education and training, improve knowledge and attitudes, equip more institutions with pulse oximeters, and popularize their application in medical institutions.

BACKGROUND: Normal tension glaucoma (NTG) is a less pressure-dependent type of glaucoma with characteristic optic neuropathy. Recently, the biomechanical mechanism has been thought to account for glaucomatous optic neuropathy to some degree. We intended to compare dynamic corneal response parameters (DCRs) among patients with primary open-angle glaucoma with normal tension or hypertension and controls. The correlations between DCRs and known risk factors for glaucoma were also analyzed. METHODS: In this cross-sectional study, 49 NTG subjects, 45 hypertension glaucoma (HTG) subjects, and 50 control subjects were enrolled. We compared the differences in DCRs using corneal visualization Scheimpflug technology among the NTG, HTG, and control groups. We also analyzed the correlations between DCRs and known risk factors for glaucoma (eg, central corneal thickness [CCT], intraocular pressure [IOP], etc). RESULTS: The maximum inverse concave radius (NTG: 0.18 [0.17, 0.20] mm-1; control: 0.17 [0.16, 0.18] mm-1; P = 0.033), deformation amplitude ratio of 2 mm (DAR 2 mm, NTG: 4.87 [4.33, 5.39]; control: 4.37 [4.07, 4.88]; P < 0.001), and DAR 1 mm (NTG: 1.62 [1.58, 1.65]; control: 1.58 [1.54, 1.61]; P < 0.001) were significantly higher in NTG than in the controls. The integrated radius (IR, NTG: 8.40 ± 1.07 mm-1; HTG: 7.64 ± 1.31 mm-1; P = 0.026) and DAR 2 mm (NTG: 4.87 [4.33, 5.39]; HTG: 4.44 [4.12, 5.02]; P < 0.007) were significantly higher, whereas the stiffness parameter at the first applanation (SP-A1, NTG: 91.23 [77.45, 107.45]; HTG: 102.36 [85.77, 125.12]; P = 0.007) was lower in NTG than in HTG. There were no significant differences in the DCRs between HTG and control groups (P > 0.05). In the univariate and multivariate analyses, some of the DCRs, such as IR, were negatively correlated with CCT and IOP, whereas SP-A1 was positively correlated with CCT and IOP. CONCLUSIONS The cornea was more deformable in NTG than in HTG or controls. There were no significant differences in corneal deformability between HTG and controls. The cornea was more deformable with the thinner cornea and lower IOP.
