Objective To investigate the effect and mechanism of long-term indwelling needle of Baihui acupoint during acupuncture on improving neurological function in ischemic stroke mice through brain-derived neurotrophic factor(BDNF)/tyrosine receptor kinase B(TrkB)pathway.Methods A total of 48 male C57BL/6J mice were randomly divided into sham group 1,model group 1,long-term indwelling needle group 1 and conventional indwelling needle group,with 12 mice in each group.A mouse model of ischemic stroke was established by thread occlusion in the latter 3 groups.From the first day after modeling,long-term and conventional indwelling needle at Baihui acupoint was given to the mice in the corresponding groups for 14 consecutive days.Anoth-er 40 male C57BL/6J mice were also subjected and randomly divided into sham group 2,model group 2,and long-term indwelling needle groups 2 and 3,with 10 mice in each group.After model-ing in the latter 3 groups,100 pl adeno-associated virus was injected by caudal vein before acu-puncture treatment.Modified neurological severity score(mNSS)and escape latency,residence time in the target quadrant,and times of crossing the original platform in water maze test were used to evaluate neural function.Results Decreased mNSS score,shorter residence time in the target quadrant,less times of crossing the original platform,and reduced expression levels of BDNF and TrkB in the ischemic brain tissue,and higher apoptotic rate and elevated level of cleaved Caspase-3 in the ischemic brain tissue were observed in the model group 1 when compared with the sham group 1(P＜0.05).While long-term and conventional indwelling needle could reverse above indicators,with long-term indwelling needle more significant than the conventional method(P＜0.05).The long-term indwelling needle group 3 obtained lower mNSS score,reduced residence time in the target quadrant,lower times of crossing the original platform and decreased levels of BDNF and TrkB in the ischemic brain tissue(P＜0.05),and higher apoptotic rate and elevated level of cleaved Caspase-3 in the ischemic brain tissue than the long-term indwelling nee-dle group 2[(16.41±2.25)％vs(7.59±1.09)％,1.46±0.16 vs 0.94±0.12,P＜0.05].Conclusion Long-term indwelling needle at Baihui acupoint more significantly improves the neurological func-tion in ischemic stroke mice than ordinary indwelling needle treatment.Its molecular mechanism is due to activating the BDNF/TrkB pathway.

Objective:To explore the feasibility and clinical effects of unilateral superior gluteal artery perforator propeller flap combined with contralateral centripetal advancement flap in repairing huge pressure ulcers in the sacrococcygeal region.Methods:The study was a retrospective observational study. From June 2020 to April 2023, 15 patients with stage Ⅳ pressure ulcers with sacrococcygeal defect area greater than 10.0 cm×10.0 cm who met the inclusion criteria were admitted to the First Affiliated Hospital of Air Force Medical University, including 8 males and 7 females, aged from 30 to 86 years. The pressure ulcers before debridement were all accompanied by different degree of infection and necrosis. Debridement and negative pressure sealing and irrigation treatment were performed in stage Ⅰ. After debridement, the skin and soft tissue defect area was 12.0 cm×10.5 cm to 20.0 cm×17.0 cm. After the wound bed infection was controlled, unilateral superior gluteal artery perforator propeller flap combined with contralateral centripetal advancement flap was used to repair the pressure ulcer wounds in stage Ⅱ. The perforator flap area was 12.0 cm×7.0 cm to 16.0 cm×10.5 cm. The donor area wound was sutured directly. After operation, the survival, complications, and wound healing of flap donor area were observed. During regular follow-up, the recurrence of pressure ulcers, the appearance and texture of the flap, and the scars in the donor site were observed.Results:After operation, 1 patient had fluid accumulation under the flap and survived after drainage and dressing change. The flaps of the other patients survived well without infection, local necrosis, and sinus formation under the flap. The wounds in the donor area healed well. All patients were followed up for more than 6 months, and there was no recurrence of pressure ulcers. The appearance of the flap was not bloated, the texture was soft, and the compression resistance and elasticity were good. The donor site wound healed well without obvious scar.Conclusions:The surgical method of repairing giant sacrococcygeal pressure ulcers with unilateral superior gluteal artery perforator propeller flap combined with contralateral centripetal advancement flap is simple and easy to operate. It can repair large defect area with the donor area being sutured directly, which is worthy of clinical promotion.

Mitochondrial myopathy is a group of multi-system diseases in which mitochondrial DNA(mtDNA)or nuclear DNA(nDNA)defects lead to structural and functional dysfunction of mitochondria.The clinical manifestations of mitochondrial myopathy are complex and varied,and the testing for mtDNA and nDNA is not widely available,so misdiagnosis or missed diagnosis is common.Chronic progressive external ophthalmoplegia(CPEO)is a common type of mitochondrial myopathy,which is characterized by blepharoptosis.Here we report a 38-year-old female with mitochondrial myopathy presented with chronic numbness and weakness of the limbs,accompanied by blepharoptosis that was recently noticed.Laboratory and head magnetic resonance imaging(MRI)examinations showed no obvious abnormalities.Muscle and nerve biopsies showed characteristic ragged red fibers(RRFs)and large aggregates of denatured mitochondria.Testing for mtDNA and nDNA showed a known mutation c.2857C＞T(p.R953C)and a novel variant c.2391G＞C(p.M797I)in the polymerase gamma(POLG)gene,so the patient was diagnosed as mitochondrial myopathy.Clinicians should pay more attention to long-term unexplained skeletal muscle diseases with recent onset blepharoptosis.Histopathologic examination and genetic testing are of great value in the early diagnosis and therapeutic intervention.

Objective:To study the relationship between endoplasmic reticulum stress (ERS) and apoptotic protein and myocardial pathological changes in rats after endostar combined with low-dose X-ray irradiation.Methods:Forty SD rats were evenly divided into four groups: control group (intraperitoneal injection of equal volume physiological saline, once per day, 14 d), endostar group (intraperitoneal injection of endostar 6 mg/kg, once per day, 14 d), irradiation group (15 Gy divided into 3 times X-ray irradiation) and combination group (intraperitoneal injection of endostar after irradiation at the same dose and time as the endostar group). At 1 and 6 months after treatment, myocardial tissues of rats were prepared for HE staining and Masson staining to observe the myocardial histological changes. TUNEL assay was used to detect myocardial cell apoptosis, and ImageJ software was utilized to calculate myocardial collagen volume fraction (CVF). The expression levels of ERS and apoptotic protein glucose-regulated protein 78 (GRP78), protein kinase-like endoplasmic reticulum kinases (PERK), CCAAT/enhancer binding protein homologous protein (CHOP) and cysteine-containing aspartate-specific protease-12 (Caspase-12) were detected by Western blot. One-way ANOVA was conducted using GraphPad Prism 8.0.1 software, and comparison between two groups was conducted using t-test. Results:At 6 months after treatment, the myocardial interstitium in the irradiation and combination groups was widened, showing strip-like or reticular fibrosis changes, and the myocardial interstitium had diffuse collagen fiber deposition. Compared with the control group, CVF was increased significantly (both P<0.01). At 1 and 6 months after treatment, the apoptotic index of myocardial cells in the combination group was significantly higher than that in the control group ( P<0.05, <0.001). At 1 and 6 months after treatment, the expression levels of GRP78 protein in the irradiation and combination groups were increased (all P<0.01), and the expression levels of PERK and CHOP proteins in the combination group were increased compared to those in the control group (both P<0.05). At 6 months after treatment, the expression levels of PERK and CHOP proteins in the irradiation group were increased compared to those in the control group (both P<0.05). Compared with the control group, Caspase-12 expression levels at 1 and 6 months after treatment were increased in the endostar, irradiation and combination groups (all P<0.05). Conclusions:The expression levels of ERS and apoptotic proteins are related to cardiac injury caused by irradiation in rats. After low-dose X-ray combined with endostar treatment, ERS is aggravated and myocardial apoptosis is increased.

Essential tremor(ET)is one of the most common movement disorders, with a prevalence of 4.6% in people over 65 years old.Action tremor of both upper limbs at 4-12 Hz action tremor in both upper limbs is the main clinical feature of ET patients.ET was previously considered to be a benign isolated symptomatic disease, but in recent years, researches have found that ET is a family of diseases with high clinical and genetic heterogeneities.In addition to tremor, it can also be accompanied by soft neurological signs and various non-motor symptoms, leading to different degrees of function impairment in patients.Early comprehensive evaluation and long-term follow-up of patients with ET are essential.The standardized scale is the most important tool for ET assessment.This article reviews various tremor assessment scales.

Essential tremor (ET) is a common movement disorder. It is characterized by a distinctive 4-12 Hz action tremor typically affecting bilateral upper limbs. Existing drugs for ET mainly include β-blockers, anticonvulsants, benzodiazepines, etc. However, the efficacy of existing drugs is limited. With the development of the medical research, some progress has been made in the treatment of ET. The review will explore the recent advances in the treatment of ET,such as new drugs, surgical treatment, repetitive transcranial magnetic stimulation, rehabilitation treatment, etc., in order to provide clinical application prospects.

OBJECTIVES: Idiopathic intracranial hypertension (IIH) is a syndrome that excludes secondary causes such as intracranial space-occupying lesion, hydrocephalus, cerebrovascular disease, and hypoxic ischemic encephalopathy. If not be treated promptly and effectively, IIH can cause severe, permanent vision disability and intractable, disabling headache. This study aims to explore the clinical and image features for IIH, to help clinicians to understand this disease, increase the diagnose rate, and improve the outcomes of patients. METHODS: We retrospectively analyzed 15 cases of IIH that were admitted to Xiangya Hospital, Central South University, during January 2015 to September 2020. The diagnosis of IIH was based on the updated modified Dandy criteria. We analyzed clinical data of patients and did statistical analysis, including age, gender, height, weight, medical history, physical examination, auxiliary examination, treatment and outcome. RESULTS: There were 10 females and 5 males. Female patients were 22 to 42 years old with median age of 39.5. Male patients were 27 to 52 years old with the median age of 44.0. The BMI was 24.14-34.17 (28.71±2.97) kg/m CONCLUSIONS IIH primarily affects women of childbearing age who are overweight. The major hazard of IIH is the severe and permanent visual loss. Typical image signs have high specificity in IIH diagnosis. Prompt diagnosis and effective treatment are significantly important to improve the outcomes of patients.

Objective:To explore the effect of evidence-based nursing best practice in postoperative pain management of neurosurgery patients.Methods:From January to June 2019, a cluster sampling method was used to select 146 neurosurgery patients from Huashan Hospital, Fudan University as the control group. We examined the patient's postoperative pain management status, and applied evidence-based nursing methods to obtain best practice evidence. From July to December 2019, the clinical evidence practice application model of the Australia Joanna Briggs Institute (JBI) Evidence-Based Health Care Center was used to apply evidence to postoperative pain management in neurosurgery patients. From January to June 2020, a cluster sampling method was used to select 146 neurosurgery patients as the observation group for re-examination after the application of evidence. The Modified American Pain Society Patient Outcome Questionnaire (APS-POQ-Modified) was used to investigate the postoperative pain perception beliefs and postoperative pain degree of the two groups of patients. The qualification rate of 146 pain nursing records before and after the application of the evidence was checked and the differences were compared.Results:The scores of 7 items regarding pain perception beliefs in control group were (3.45±1.42) , (3.21±1.21) , (3.58±1.53) , (3.37±1.26) , (3.63±1.34) , (3.55±1.06) , (3.45±1.35) , and those of observation group were (2.44±1.31) , (2.35±1.21) , (2.34±1.35) , (3.06±1.17) , (2.57±1.25) , (3.05±1.02) , (3.12±1.42) , the differences between the two groups were statistically significant ( t=6.346, 6.057, 7.350, 2.166, 6.994, 4.108, 2.027; P<0.05) . In control group, the current pain degree score was (2.34±0.89) , the most severe pain degree score within 24 hours after operation was (4.44±1.17) , and the average pain degree score within 24 hours after operation was (3.21±0.75) , and the scores in observation group were (1.98±0.96) , (3.54±1.10) , (2.46±0.70) , and the differences were statistically significant ( t=3.355, 6.731, 8.808; P<0.01) . The qualification rate of pain nursing record sheet before and after the application of the evidence was 67.12% (98/146) and 82.88% (121/146) respectively, the difference was statistically significant (χ 2=9.662, P=0.002) . Conclusions:The evidence-based nursing best practice can improve neurosurgery patients' pain perception beliefs, reduce the degree of postoperative pain of patients, and increase the qualification rate of nurses' pain nursing records.

In the clinical settings, disseminated intravascular coagulation (DIC) and complications such as hemorrhage are commonly seen in acute promyelocytic leukemia patients, whereas thrombosis is rarely reported. We reported a case here that the patient presented with cerebral infarction as the first manifestation. During the admission, the patient encountered differentiation syndrome, pulmonary embolism, pulmonary hemorrhage, and myocardial ischemia, as well as bleeding and thrombosis complications. Hence the patient was diagnosed as DIC. After the treatment of blood transfusion instead of anticoagulation, his condition was stable and the remission was completely achieved. The treatment experience provides guides for other patients with similar complications of simultaneous bleeding and thrombosis.

Objective:To investigate and analyze disease status and risk factors of venous thromboembolism (VTE) during pregnancy and puerperium in our country.Methods:Clinical datas were collected from 575 patients diagnosed with VTE during pregnancy and puerperium and hospitalized in nine medical institutions in our country from January 1, 2015 to November 30, 2019, and retrospectively analyzed it′s disease status and risk factors.Results:(1) The proportion of VTE in pregnancy and puerperium was 50.6% (291/575) and 49.4% (284/575), respectively. Four patients died, the mortality rate was 0.7% (4/575). The cause of death was pulmonary embolism. (2) The location of VTE during pregnancy and puerperium was mainly in the lower limb vascular (76.2%, 438/575), followed by pulmonary vessels (7.1%, 41/575). (3) In the risk factors of VTE, cesarean section accounted for 32.3% (186/575), maternal advance age accounted for 27.7% (159/575), braking or hospitalization during pregnancy accounted for 13.6% (78/575), other risk factors accounted for more than 5% were previous VTE, obesity, preterm birth, assistant reproductive technology conception and so on, pre-eclampsia and multiple pregnancy accounted for 4.9% (28/575) respectively. In addition, some patients with VTE did not have any of the above risk factors, and the incidence rate was as high as 23.1% (133/575).Conclusions:The occurrence of VTE during pregnancy and puerperium is related to multiple risk factors, and could lead to matemal death, It is very necessary to screen VTE risk factors for all pregnant women, to make corresponding prevention and control measures.
