Objective:To explore the effect of family empowerment model on the improvement of swallowing care ability and care preparedness of primary caregivers of first-episode stroke dysphagia patients, further to explore its impact on patients′s wallowing function and life quality.Methods:This study was a randomized controlled study. From January 2021 to December 2022, 80 main caregivers of patients with dysphagia caused by manual stroke admitted to the Department of Acupuncture and Moxibustion, Shenzhen Hospital of Traditional Chinese Medicine were selected as the research objects, and 40 cases in the control group and 40 cases in the observation group were selected by random number table method. The control group were treated with conventional nursing care of first-episode stroke dysphagia patients in the acupuncture and moxibustion Department. On the basis of the conventional care in the control group, the observation group were treated with family empowerment model intervention for 14 days and was followed up for 28 days. Primary caregivers′ swallowing care ability, Caregiver Preparedness Scale (CPS), patients′ swallowing function rate, Swallowing Related Quality of Life (SWALQOL) were used to evaluate the effects before intervention and at the end of intervention.Results:There were 18 males and 19 females primary caregivers in the control group, aged (55.61 ± 7.43) years old. There were 18 males and 21 females primary caregivers in the observation group, aged (58.23 ± 8.22) years old. The swallowing care ability score showed a statistically significant difference between the observation group (143.47 ± 3.96) and the control group (107.74 ± 1.43) ( t=-26.76, P<0.05). After intervention, the caregiver preparedness scale was (26.11 ± 3.81) in the observation group, and (18.35 ± 4.54) in the control group, and the difference was statistically significant ( t=-4.11, P<0.05).The patients′ swallowing function rate and SWALQOL score were respectively 97.44% (38/39) and (91.41 ± 8.08) points in the observation group, and 72.97% (27/37) and (80.33 ± 4.21) points in the control group, and the difference was both statistically significant ( χ2=10.76, t=-2.54, both P<0.05). Conclusions:The implementation of family empowerment model could enhance the swallowing care ability and care preparedness of primary caregivers of the first-episode stroke dysphagia patients, which could further improve patients′ swallowing function and life quality.

Objective:To investigate the consistency of domestic F-STROKE, NeuBrainCARE MRI automatic post-processing software and RAPID MRI automatic post-processing software in the output of infarction core area volume, time-to-maximum volume and ischemic penumbra volume in patients with acute ischemic stroke.Methods:The research was cross-sectional. The clinical and imaging data of patients with acute ischemic stroke from January 2016 to March 2021 were retrospectively collected, including 149 cases from Shanghai Fourth People′s Hospital Affiliated to Tongji University (Center 1), 120 cases from Langfang Changzheng Hospital of Hebei Province (Center 2), and 45 cases from Wuzhou Workers Hospital (Center 3). All patients underwent diffusion weighted imaging (DWI) and dynamic magnetic sensitivity contrast-perfusion weighted imaging (DSC-PWI). RAPID, F-STROKE and NeuBrainCARE automatic post-processing software were used to perform automatic post-processing analysis of MRI images of all patients with acute ischemic stroke. The infarct core (apparent diffusion coefficient<620×10 -6 mm 2/s) volume, time-to-maximum (T max>6 s) volume and the ischemic penumbra (PWI-DWI mismatch) volume were output. The Wilcoxon test was used to analyze the difference between F-STROKE, NeuBrainCARE, and RAPID software outputs of infarct core volume, time to maximum peak volume, and ischemic penumbra volume. Bland-Altman and intraclass correlation coefficient ( ICC) were used to analyze the consistency of the infarct core volume, time-to-maximum volume and ischemic penumbra volume output by F-STROKE, NeuBrainCARE and RAPID software. Results:There were statistically significant differences in the core infarct volume between F-STROKE and RAPID software, NeuBrainCARE and RAPID software ( Z=-10.17, -5.43, both P<0.001). There were significant differences in the time-to-maximum volume between F-STROKE and RAPID software, NeuBrainCARE and RAPID software ( Z=-3.17, -5.51, both P<0.05). There was no significant difference in the ischemic penumbra volume between F-STROKE software and RAPID software ( Z=-1.43, P=0.153), and there was significant difference in the ischemic penumbra volume between NeuBrainCARE software and RAPID software ( Z=-6.45, P<0.05). Bland-Altman analysis showed that the values within the limits of agreement accounted for more than 93.31% of all point values. ICC analysis showed high agreement between F-STROKE, NeuBrainCARE, and RAPID software outputs of infarct core volume, time to maximum peak volume, and ischemic penumbra volume ( ICC>0.6). Conclusion:Domestic F-STROKE software, NeuBrainCARE software and RAPID software have good consistency in evaluating the infarct core volume, time-to-maximum volume and ischemic penumbra volume in patients with acute ischemic stroke, which is worthy of clinical promotion.

Objective To analyze the causal relationship between serum sex steroid hormone levels and myopia with the Mendelian randomization(MR)methods.Methods Sex hormone genetic tools classified by sex were publicly availa-ble summarized statistical data from the Genome-wide association study(GWAS)of the UK Biobank Consortium on sex hormone-binding globulin(SHBG),total testosterone(TT),bioavailable testosterone(BT),and estradiol(E2).The GWAS summarized statistical data for myopia were obtained from publicly available data published by the FinnGen Consorti-um R10.All data were downloaded from April 18 to April 31,2024 from the corresponding databases and analyzed.All re-sults from the MR study were mainly analyzed by inverse-variance weighting(IVW)method.Results The study showed that a higher serum SHBG level in European increased the risk of myopia development in women(IVW,OR=1.152,95％CI:1.014-1.308,P=0.029);low serum TT level(IVW,OR=0.821,95％CI:0.697-0.967,P=0.018)and serum BT lev-el(IVW,OR=0.820,95％CI:0.691-0.972,P=0.022)increased the risk of myopia development in women.There was no causal relationship between serum SHBG,TT,and BT levels and myopia in men.There was no causal effect between E2 level and myopia in women and men.The stability of our findings was supported by sensitivity analysis.Conclusion In-creased serum SHBG level and decreased serum TT and BT levels are associated with an increased risk of myopia in women,whereas no such association is found in men.There is no causal relationship between E2 and myopia.

Hepatic alveolar echinococcosis (HAE) is a parasitic disease caused by Echinococcus multilocularis infection and has wide distribution and great harm in China. At present, ultrasound, CT, and MRI are the main radiological examination methods for HAE, with certain limitations in preoperative diagnosis and evaluation. This article introduces the guiding effect of three-dimensional visualization technique and its derivative technologies in the accurate diagnosis and preoperative evaluation of HAE, so as to provide help for the clinical diagnosis and treatment of HAE in the future.

Objective:To evaluate the effect of muscle oxygen saturation (SmtO 2) guidance on the quality of early recovery after spinal surgery in the patients. Methods:One hundred and twenty patients of either sex, aged 18-64 yr, with body mass index of 18-35 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, with Hb concentration>100 g/L, undergoing elective spinal surgery, were selected.Routine anesthesia induction and maintenance were performed.SmtO 2 monitoring was carried out, and electrodes were applied to bilateral thenar in group S. When unilateral or bilateral SmtO 2 dropped to 70% of the baseline level for more than 60 s, the sensor position was checked, fluid infusion was accelerated, vasoconstrictors was used, and the inhaled oxygen concentration was improved and blood was transfused for treatment.In group C, only electrode sheets were applied, without monitoring.The Quality of Recovery-15 scale was used to evaluate the recovery quality of patients at 1 day before operation (T 0), 1 day after operation (T 1) and 3 days after operation (T 2). The tracheal extubation time, post-anesthesia care unit stay time and postoperative length of hospital stay were recorded.Immediately before anesthesia induction and at the end of operation, arterial blood was collected for blood gas analysis, and the lactic acid level was recorded.Postoperative hypotension, constipation, spinal nerve injury, postoperative nausea and vomiting and incisional infection were recorded. Results:Compared with group C, the level of postoperative lactic acid was significantly decreased, the incidence of postoperative constipation, postoperative nausea and vomiting and incisional infection was decreased, the extubation time and post-anesthesia care unit stay time were shortened, and the Quality of Recovery-15 scale score at T 1, 2 was increased in group S ( P<0.05). Conclusions:SmtO 2 guidance can improve the early recovery quality of patients after lumbar surgery.

Objective:To evaluate the efficacy of long-pulsed 1 064-nm Nd:YAG laser combined with a topical emulsion containing Camellia reticulata and Radix Notoginseng in the treatment of melasma. Methods:A total of 80 patients with melasma were enrolled from Department of Dermatology, People′s Hospital of Ningxia Hui Autonomous Region from June 2019 to June 2020, and randomly and equally divided into control group and observation group by using a random number table: 40 patients in the control group were treated with long-pulsed 1 064-nm Nd:YAG laser once every 2 weeks for 6 sessions as a course of treatment; another 40 in the observation group were treated with the same laser therapy as the control group and a topical emulsion containing Camellia reticulata and Radix Notoginseng twice a day for 3 months as a course of treatment. Melasma area and severity index (MASI), clinical efficacy, patient satisfaction rate and safety were compared between the 2 groups before and/or after treatment. Results:After 4- and 8-week treatment, there was no significant difference in the MASI score between the observation group (14.57 ± 3.22 points, 10.00 ± 2.94 points, respectively) and control group (14.74 ± 3.11 points, 11.31 ± 3.00 points, respectively; both P>0.05). After 12-week treatment, the MASI score was significantly lower in the observation group (4.80 ± 2.78 points) than in the control group (7.07 ± 3.22 points, t = -3.38, P<0.01). After 3-month treatment, the response rate was significantly higher in the observation group (36 cases, 90%) than in the control group (31 cases, 77.5%; χ2 = 4.58, P < 0.001) ; however, there was no significant difference in the patient satisfaction rate between the observation group (87.5%) and control group (72.5%, χ2 = 7.26, P = 0.06). In addition, no significant difference in the occurrence of adverse reactions was observed between the observation group (5 cases, 12.5%) and control group (7 cases, 17.5%; P > 0.05) . Conclusion:Compared with the long-pulsed 1 064-nm Nd:YAG laser alone, the topical emulsion containing Camellia reticulata and Radix Notoginseng in combination with the long-pulsed 1 064-nm Nd:YAG laser is more effective for the treatment of melasma, with higher patient satisfaction and less adverse reactions.

Objective:To investigate the effect of intraoperative blood transfusion on postoperative deep vein thrombosis in patients with orthopedic trauma.Methods:A retrospective analysis was conducted of the 502 patients who had been treated operatively at Department of Orthopaedics and Trauma, Xi＇an Honghui Hospital from January 2015 to September 2018. They were divided into 2 groups according to the use of intraoperative blood transfusion. In the observation group of 203 cases who had received intraoperative blood transfusion, there were 98 males and 105 females with an age of (61.0±20.7) years; in the control group of 299 cases who had not received intraoperative blood transfusion, there were 166 males and 133 females with an age of (57.7±19.0) years. Blood coagulation series such as D-dimer and fibrinogen were measured at admission, 1 day pre-operation, 1 day and 3 days postoperation. After operation, venous ultrasound examination of both lower limbs was performed to observe postoperative DVT in the patients. The 2 groups were compared in changes in coagulation series and occurrence of postoperative DVT.Results:There was no statistically significant difference in the preoperative general data between the 2 groups ( P>0.05), showing they were comparable. There was no significant difference between the observation group and the control group in the D-dimer level at admission or 1 day pre-operation ( P>0.05), but the D-dimer levels at 1 day and 3 days postoperation in the observation group [4.18 (2.35, 7.08) mg/L and (6.20±3.77) mg/L] were significantly higher than those in the control group [3.41 (1.91, 5.63) mg/L and (4.05±2.62) mg/L] ( P<0.05). There was no statistically significant difference in fibrinogen between the 2 groups at different time points ( P>0.05). The incidence of DVT in the observation group was 43.3% (88/203), significantly higher than that in the control group (32.8%, 98/299) ( P<0.05). Conclusion:As intraoperative blood transfusion can increase the level of D-dimer and thus the incidence of postoperative venous thrombosis in patients with orthopaedic trauma, we should pay more attention to the risk of postoperative DVT in patients receiving intraoperative blood transfusion.

Objective:To evaluate the effect of transcutaneous electrical acupoint stimulation (TEAS) on perioperative anxiety and postoperative pain in living kidney donors (LKDs).Methods:Seventy-two American Society of Anesthesiologists physical status Ⅰ or Ⅱ LKDs, aged 18-64 yr, with body mass index of 18-28 kg/m 2, undergoing living kidney transplantation, were selected, and divided into 2 groups ( n=36 each) using a random number table method: TEAS group (group T) and sham stimulation group (group S). In group T, TEAS was performed on the forenoon at 1 day before surgery (T 0), at 30 min before anesthesia induction on the morning of the operation day (T 1) and on the forenoon at 1 day after surgery (T 2) at bilateral Neiguan, Taichong and Yintang with a frequency 2-100 Hz, disperse-dense waves and current intensity 6-15 mA, and each TEAS lasted for 30 min.Only electrode patches were applied at the same acupoint and at the same time point, but no stimulation was applied in group S. In T and S groups, brachial venous blood samples were collected before each stimulation for measurement of the plasma 5-hydroxytryptamine (5-HT) concentration.The Hospital Anxiety Depression Scale-Anxiety subscale (HADS-A) scores at T 0, T 1, T 2, on day 3 after surgery (T 3) and before discharge (T 4) in the 2 groups were recorded.The consumption of anesthetics during operation, laryngeal mask airway removal time, requirement for rescue analgesia within 72 h after surgery and the development of postoperative complications were recorded.The LKDs were followed up by telephone at 3 months after surgery (T 5) to record the scores of HADS-A and Leeds Assessment of Neuropathic Symptoms and Sign (LANSS) scale. Results:Compared to group S, the incidence of anxiety was significantly decreased T 1, T 2 and T 3, the incidence of rescue analgesia within 72 h after surgery was decreased, plasma concentration of 5-HT was increased at T 1 and T 2, the incidence of postoperative nausea and vomiting was decreased, and the time to first flatus was shortened in group T ( P<0.05). There was no significant difference in the consumption of anesthetics during operation, laryngeal mask airway removal time, and the incidence of anxiety and neuropathic pain within 3 months after surgery between the 2 groups ( P>0.05). Conclusion:TEAS can relieve early preoperative and postoperative anxiety and alleviate postoperative pain in LKDs.

OBJECTIVE: To explore the genetic basis for a pedigree affected with hereditary spastic paraplegia type 4 (HSP4). METHODS: Peripheral venous blood samples were taken from members of the four-generation pedigree and 50 healthy controls for the extraction of genomic DNA. Genes associated with peripheral neuropathy and hereditary spastic paraplegia were captured and subjected to targeted capture and next-generation sequencing. The results were confirmed by Sanger sequencing. RESULTS: DNA sequencing suggested that the proband has carried a heterozygous c.1196C>G variant in exon 9 of the SPAST gene, which can cause substitution of serine by threonine at position 399 (p.Ser399Trp) and lead to change in the protein function. The same variant was also detected in other patients from the pedigree but not among unaffected individuals or the 50 healthy controls. Based on the ACMG 2015 guidelines, the variant was predicted to be possibly pathogenic. CONCLUSION The c.1196C>G variant of the SPAST gene probably underlay the HSP4 in this pedigree.

Objective:To explore the clinical efficacy of proximal femoral anatomical locking plate and autogenous iliac graft for failed primary internal fixation in treatment of femoral intertrochanteric fracture.Methods:A retrospective analysis was conducted of the 29 patients with femoral intertrochanteric fracture who had been treated after failed primary internal fixation at Department of Orthopaedics and Trauma, Xi'an Honghui Hospital between January 2014 and March 2017. They were 17 men and 12 women, aged from 35 to 83 years (mean, 68.7 years). Their primary internal fixation involved dynamic hip screw in 12 cases, proximal femoral locking plate in 13 cases, and intramedullary nail in 4 cases. The causes for their internal fixation failure included head cutting in 8 cases, fracture nonunion in 10 cases, plate or screw breakage in 6 cases, intramedullary nail breakage in 3 cases, and hip varus in 2 cases. Their revision surgery was performed with anatomical proximal femoral locking plate and autogenous iliac bone graft. Their fracture union time, and visual analogue scale (VAS), hip Harris score, SF-36 health survey scale and complications at the final follow-ups were recorded.Results:All the 29 patients were followed up for 12 to 24 months (18 months on average). Bony union was eventually achieved in all the 29 patients after an average time of 4.5 months (from 3 to 7 months). There were no such complications as nonunion, re-fracture or internal fixation failure. The VAS pain score at the final follow-up(4.6±1.6) was significantly lower than that before surgery(7.1±2.1), and the Harris hip score(85.2±8.2) and SF-36 score(75.9±15.5) at the final follow-up were significantly higher than those before surgery (48.0±12.7 and 48.7±18.8) (all P<0.05). According to their hip Harris scores at the final follow-ups, the therapeutic efficacy was rated as excellent in 9 cases, as good in 15 cases and as poor in one, yielding an excellent and good rate of 82.8%. Conclusion:For patients with femoral intertrochanteric fracture whose primary internal fixation has failed, especially those with fine femoral head and neck and hip joint, proximal femoral anatomic locking plate and autogenous iliac bone graft can result in satisfactory clinical efficacy.
