To summarize Professor GAO Shuzhong's clinical experience in treating idiopathic tinnitus with a combination of acupuncture and Chinese meteria medica. It is believed that idiopathic tinnitus is mostly caused by weak lungs and spleen， kidney essence deficiency， liver constraint transforming into fire， and binding constraint of heart qi. Treatment advocates the combination of acupuncture and Chinese meteria medica in clinical practice. Acupuncture treatment mainly focus on the method of opening the orifices by syndrome identification in combination with Ermen （TE 21）， Tinggong （SI 19）， Tinghui （GB 2）， Shenmai （BL 62） to regulate qi and blood， and supporting with Baihui （GV 20）， Yintang （EX-HN 3）， Taichong （LR 3）， and Yanglingquan （GB 34） to soothe the liver， resolve constraint， and calm the mind. Oral administration of Chinese medicinal prescription usually includes modified Yiqi Congming Decoction （益气聪明汤） and Tongqi Powder （通气散）， and the external administration of Chinese medicinal prescription can apply self-prescribed Wenqing Powder （温清散） to navel moxibustion.

ObjectiveTo explore the mechanism of Hei Xiaoyaosan in improving the cognitive function in Alzheimer's disease （AD） from cell apoptosis mediated by the phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/nuclear factor kappa B （NF-κB） signaling pathway. MethodsFour-month-old SD male rats were randomly assigned into a blank group， a sham group， a model group， a donepezil hydrochloride （0.45 mg·kg^-1） group， and high-， medium-， and low-dose （15.30， 7.65， and 3.82 g·kg^-1， respectively） Hei Xiaoyaosan groups， with 10 rats in each group. The sham group received bilateral hippocampal injection of 1 μL normal saline， while the other groups received bilateral hippocampal injection of 1 μL beta-amyloid 1-42 （Aβ_1-42） solution for the modeling of AD. Rats were administrated with corresponding agents once a day for 42 consecutive days. The Morris water maze test was carried out to assess the learning and memory abilities of rats. Hematoxylin-eosin staining was employed to observe pathological changes in the hippocampus of rats. Enzyme-linked immunosorbent assay was employed to measure the levels of cysteinyl aspartate-specific proteinase-3 （Caspase-3）， B-cell lymphoma-2 （Bcl-2）， and Bcl-2-associated X protein （Bax）. Western blot was employed to determine the protein levels of PI3K， Akt， and NF-κB. A cell model of AD was established by co-culturing Aβ_1-42 and PC12 cells in vitro. Cell viability and apoptosis were detected by the cell-counting kit 8 （CCK-8） assay and flow cytometry （FC）， respectively. ResultsAnimal experiments showed that compared with the blank group， the model group had a prolonged escape latency （P<0.01）， a reduced number of crossing platforms （P<0.01）， disarrangement and a reduced number of hippocampal neurons， up-regulated expression of Bax and Caspase-3， down-regulated expression of Bcl-2 （P<0.01）， decreased p-PI3K/PI3K and p-Akt/Akt levels， and an increased p-NF-κB/NF-κB level （P<0.01）. Compared with the model group， donepezil hydrochloride and high- and medium-dose Hei Xiaoyaosan shortened the escape latency and increased the number of crossing platforms （P<0.05， P<0.01）， improved the arrangement and increased the number of hippocampal neurons， down-regulated the expression levels of Bax and Caspase-3， up-reguated the expression level of Bcl-2 （P<0.05， P<0.01）， increased the p-PI3K/PI3K and p-Akt/Akt levels （P<0.05， P<0.01）， and reduced the p-NF-κB/NF-κB level （P<0.05， P<0.01）. Cell experiments showed that compared with the blank group， the model group exhibited an increased apoptosis rate （P<0.01）. Compared with the model group， the serum containing Hei Xiaoyaosan at various doses improved the cell viability （P<0.01）， and the serum containing Hei Xiaoyaosan at the high dose decreased the cell apoptosis （P<0.01）. ConclusionHei Xiaoyaosan may improve the learning and memory abilities of AD model rats by regulating cell apoptosis， while increasing the vitality and reducing the apoptosis rate of AD model cells via the PI3K/Akt/NF-κB signaling pathway.

ObjectiveTo explore the mechanism of Huanglian Wendantang on damp-heat type diabetes enteropathy rats based on the G protein coupled bile acid receptor 5/glucagon like peptide-1 （TGR5/GLP-1） signaling pathway and intestinal flora. MethodsA total of 72 male Sprague Dawley （SD） rats were adaptively fed for one week. Twelve SD rats were randomly selected as a blank group and fed with an ordinary diet. The rest of the SD rats were fasted for 12 hours without water. A rat model with damp-heat type diabetes enteropathy was made by left intraperitoneal injection of streptozotocin （55 mg·kg^-1） and high sugar and high fat diet （20% sucrose solution + high fat diet） in a humid and hot environment （artificial climate box： temperature 30-34 ℃， relative humidity： 85%-95%）. After successful modeling， the rats were randomly divided into a model group， a metformin group （200 mg·kg^-1）， low-dose， medium-dose， and high-dose Huanglian Wendantang groups （7.10， 14.20， 28.39 g·kg^-1）， with 12 rats in each group. The normal group and the model group were orally administered with physiological saline once a day for 6 consecutive weeks. During the observation period， the weight and blood glucose levels of rats were measured and recorded weekly. After the administration， fresh feces were collected from rats， and 16S rRNA sequencing technology was used to study the differences and changes in intestinal flora among different groups. The levels of tumor necrosis factor-α （TNF-α） and interleukin-6 （IL-6） in the serum of rats were detected by enzyme-linked immunosorbent assay （ELISA）， and the pathological morphological changes of colon tissue were examined. The expression of TGR5 and GLP-1 in colon tissue was detected by immunohistochemistry， and the expression of TGR5 and GLP-1 proteins in colon tissue was measured by Western blot. ResultsCompared with the blank group， the model group showed a decrease in body weight， an increase in blood glucose， and significant damp-heat symptoms. The levels of IL-6 and TNF-α in serum were significantly increased （P<0.01）. The expression of TGR5 and GLP-1 was decreased （P<0.01）， and the pathogenic bacteria were increased. Compared with the model group， the treatment groups exhibited improvements in body weight， blood glucose levels， and damp-heat syndrome in rats. Among them， the high-dose group of Huanglian Wendantang displayed the most significant improvement effect， with significantly reduced inflammation levels （P<0.01） and elevated expression of TGR5 and GLP-1 （P<0.01）. Colonic pathological sections showed that Huanglian Wendantang could effectively ameliorate colonic pathological changes. The 16S rRNA sequencing result indicated a significant increase in beneficial bacteria in the treatment groups. ConclusionHuanglian Wendantang can effectively ameliorate the damp-heat symptoms and blood glucose levels in rats with damp-heat type diabetes enteropathy， and it may exert an effect by regulating the TGR5/GLP-1 signaling pathway and intestinal flora disorder.

Objective To investigate the feasibility and clinical experience of kidney transplantation from donors with Marfan syndrome (MFS). Methods Clinical data of 2 recipients undergoing kidney transplantation from the same MFS patient were retrospectively analyzed and literature review of 2 cases was conducted. Characteristics and clinical diagnosis and treatment of kidney transplantation from MFS patients were summarized. Results The Remuzzi scores of the left and right donor kidneys of the MFS patient during time-zero biopsy were 1 and 2. No significant difference was observed in the renal arteriole wall compared with other donors of brain death and cardiac death. Two recipients who received kidney transplantation from the MFS patient suffered from postoperative delayed graft function. After short-term hemodialysis, the graft function of the recipients received the left and right kidney began to gradually recover at postoperative 10 d and 20 d. After discharge, serum creatinine level of the recipient received the left kidney was ranged from 80 to 90 μmol/L, whereas that of the recipient received the right kidney kept declining, and the lowest serum creatinine level was 232 μmol/L before the submission date (at postoperative 43 d). Through literature review, two cases successfully undergoing kidney transplantation from the same MFS donor were reported. Both two recipients experienced delayed graft function, and then renal function was restored to normal. Until the publication date, 1 recipient has survived for 6 years, and the other recipient died of de novo cerebrovascular disease at postoperative 2 years. Conclusions MFS patients may serve as an acceptable source of kidney donors. However, the willingness and general conditions of the recipients should be carefully evaluated before kidney transplantation. Intraoperatively, potential risk of tear of renal arterial media should be properly treated. Extensive attention should be paid to the incidence of postoperative complications.

OBJECTIVE: To summarize the research progress on the mechanism related to traumatic brain injury (TBI) to promote fracture healing, and to provide theoretical basis for clinical treatment of fracture non-union. METHODS: The research literature on TBI to promote fracture healing at home and abroad was reviewed, the role of TBI in fracture healing was summarized from three aspects of nerves, body fluids, and immunity, to explore new ideas for the treatment of fracture non-union. RESULTS: Numerous studies have shown that fracture healing is faster in patients with fracture combined with TBI than in patients with simple fracture. It is found that the expression of various cytokines and hormones in the body fluids of patients with fracture and TBI is significantly higher than that of patients with simple fracture, and the neurofactors released by the nervous system reaches the fracture site through the damaged blood-brain barrier, and the chemotaxis and aggregation of inflammatory cells and inflammatory factors at the fracture end of patients with combined TBI also differs significantly from those of patients with simple fracture. A complex network of humoral, neural, and immunomodulatory networks together promote regeneration of blood vessels at the fracture site, osteoblasts differentiation, and inhibition of osteoclasts activity. CONCLUSION TBI promotes fracture healing through a complex network of neural, humoral, and immunomodulatory, and can treat fracture non-union by intervening in the perifracture microenvironment.

Objective:To study the effects of recombinant human erythropoietin (rhEPO) on cerebral blood flow (CBF) in preterm infants using arterial spin labeling (ASL) magnetic resonance imaging (MRI).Methods:From September 2021 to June 2022, preterm infants (gestational age ≤32 weeks, birth weight ≤1 500 g) admitted to NICU of our hospital within 24 h after birth were randomly assigned into rhEPO group and control group for this prospective study. The rhEPO group was given rhEPO (500 IU/kg iv, once every other day for 2 weeks) within 72 h after birth plus symptomatic supportive treatment. The control group received same amount of normal saline injection. Both groups received brain MRI, diffusion-weighted imaging and ASL at adjusted gestational age of 35~37 weeks and CBF values of interested areas were measured.Results:A total of 85 infants were enrolled, including 40 in the rhEPO group and 45 in the control group. No significant differences existed in the incidences of periventricular-intraventricular hemorrhage, periventricular leukomalacia, focal white matter injury and extensive white matter injury between the two groups ( P>0.05). The CBF values [ml/(100 g·min)] of frontal cortex [left 15.1±3.9 vs. 17.9±3.1, right 15.9 (12.5, 17.8) vs. 18.1(16.1,20.2)], temporal cortex [left 15.8±4.3 vs. 18.6±3.8, right 16.3(13.2,19.4) vs. 18.1(15.7,19.7)], occipital cortex (left 15.8±6.1 vs. 18.8±3.3, right 16.8±5.5 vs. 19.3±4.8), basal ganglia (left 24.7±7.2 vs. 28.7±6.2, right 26.0±7.9 vs. 29.3±6.4) and thalamus (left 32.7±11.8 vs. 37.9±8.6, right 32.1±11.6 vs. 37.6±10.2) in the rhEPO group were significantly lower than the control group ( P<0.05). No significant differences existed of CBF value at the parietal cortex between the two groups ( P>0.05). Conclusions:Early application of rhEPO can reduce CBF in premature infants, which may be related to the neuro-protective effects of EPO.

Objective:To study the current status of critical neonatal care centers (CNCC) construction and treatment of critically-ill neonates at city- and county-level in Henan Province.Methods:A questionnaire survey was conducted in January 2022 to city- and county-level CNCC in Henan Province. The basic information of CNCC, ward settings, neonatal management in the Department of Obstetrics and the treatment of critically-ill neonates in 2019-2021 were analyzed.Results:A total of 188 questionnaires were sent and 183 (97.3%) eligible questionnaires were analyzed, including 30 from city centers and 153 from county centers. The bed occupancy rate in county centers was significantly lower than city centers (67.3%±24.1% vs. 86.1%±23.2%), and the doctor/bed ratio, doctor/rescue bed ratio and nurse/rescue bed ratio were significantly higher than city centers ( P<0.05). All city centers had set up independent Department of Neonatology and the number is 92.8% (142/153) in county center. For 80.9% (148/183) centers, neonates were managed in the Department of Obstetrics with consultations and referrals to the Department of Pediatrics and 19.1% (35/183) were managed in the Department of Pediatrics/Neonatology. The average number of deliveries and admissions to the Department of Neonatology in both city and county centers decreased year on year during 2019-2021, but the proportion of premature and low/very low birth weight infants treated in these centers increased year on year. During 2019-2021, the top three diseases treated at the city centers were neonatal respiratory distress syndrome, neonatal asphyxia and acute respiratory distress syndrome, while the top three diseases treated at the county centers were neonatal asphyxia, neonatal respiratory distress syndrome and meconium aspiration syndrome. The incidence of sudden infant death syndrome in city and county centers was (10~30)/100,000. Conclusions:The construction of CNCC in Henan Province is facing challenges such as decreased hospital admissions, increased critically-ill neonates, insufficient cooperation between Obstetrics and Pediatrics and waste of resources. Rationally allocated and optimised use of resources to improve the ability to treat critically-ill neonates is warranted.

Objective:To explore the effect of Xingnao Kaiqiao acupuncture treatment on brain network reorganization for the patients with stroke recovery, and therefore understand the neural mechanism underlying Xingnao Kaiqiao acupuncture treatment.Methods:Prospective case series study. Thirteen acute ischemia stroke patients were recruited from the Department of Neurology, Shanghai Minhang Hospital of Integrated Traditional Chinese and Western Medicine from Aug 2018 to Oct 2019. They were treated with Xingnao Kaiqiao acupuncture once a day for 10 consecutive days in addition to routine treatments, and received clinical assessments before treatment and 14 days after treatment onset. EEG signals were recorded during the first acupuncture treatment, from before inserting the needles (the baseline), during needle retention, to after removal of the needles. The brain network was constructed using phase locking index, and its clustering coefficient (CC), characteristic path length (PL) and small-worldness (S) were analyzed using one-way repeated ANOVA.Results:Compared with the baseline, the CC of delta-band network (sparsity=0.10: t=3.306, P=0.006; 0.12: t=2.909, P=0.013; 0.14: t=2.331, P=0.038) and the PL of delta-band (sparsity=0.12: t=3.236, P=0.007; 0.14: t=2.754, P=0.017, 0.18: t=2.878, P=0.014) and alpha-band (sparsity=0.10: t=2.432, P=0.032) networks were significantly decreased during the needle retention stage. Clinical assessments demonstrated a significant treatment efficacy of Xingnao Kaiqiao acupuncture, and its efficacy which was indicated by improved NIHSS score, was significantly correlated with the CC changes in the delta band network from baseline to needle retention. The correlation was strongest when the network sparsity was 0.12 ( r=0.78, P=0.002). Conclusion:Xingnao Kaiqiao acupuncture can regulate the brain network of stroke patients in real time, and this immediate regulation maybe associated with its treatment effect.

Objective:To investigate the characteristics of multimodal ultrasound imaging in elderly hyperlipidemia patients with statin-related myopathy and to provide a reference of new method for non-invasive quantitative evaluation on statin myopathy.Methods:We collected 20 elderly hyperlipidemia patients with statin-related myopathy(the statin-related myopathy group), 20 elderly hyperlipidemia patients without statin-related myopathy after taking statins during the same period(the non-statin-related myopathy group), and 20 healthy volunteers who matched the age and sex of the above two groups during the same period(the healthy control group)in our hospital.Two-dimensional ultrasound, shear wave elastography and superb microvascular imaging were used to obtain thickness, echo, pinnation angle and shear wave velocity(SWV)values as well as vascular index(VI)values of the medial gastrocnemius during relaxation, dorsiflexion, and plantar flexion for each group, which were then analyzed.Results:There were no significant differences among the three groups in general conditions such as age, height, weight, and body mass index(all P>0.05). The mean thickness of the medial gastrocnemius in the statin-related myopathy group was about(1.04 ± 0.20)cm, which was less than(1.34 ± 0.16)cm in the non-statin-related myopathy group and(1.35 ± 0.15)cm in the healthy control group( F=22.03, P<0.001). The pinnation angle in the statin-related myopathy group was about(12.50 ± 1.10), which was less than(18.55 ± 1.28)in the non-statin-related myopathy group and(18.60 ± 1.35)in the healthy control group( F=158.03, P<0.001). Compared with the non-statin-related myopathy group and the healthy control group, SWV during resting, dorsiflexion and plantar flexion in the statin-related myopathy group decreased( F=61.71, 111.96 and 8.69, respectively, P<0.01). The average value of VI in the statin-related myopathy group was about(0.43 ± 0.12)%, which was less than that in the non-statin-related myopathy group(0.75 ± 0.20)% and in the healthy control group(0.93 ± 0.17)%( F=48.93, P<0.001). However, there was no significant difference in values from the parameters between the non-statin-related myopathy group and the healthy control group(all P>0.05). Conclusions:Multimodal ultrasound imaging of statin-related myopathy in elderly hyperlipidemia patients shows distinct characteristics and can be used to evaluate muscle damage of statin-related myopathy.

Objective:To analyze the risk factors of bronchopulmonary dysplasia(BPD)in very preterm infants(VPI), and to provide scientific basis for the prevention and treatment of BPD in VPI.Methods:A prospective multicenter study was designed to collect the clinical data of VPI in department of neonatology of 28 hospitals in 7 regions from September 2019 to December 2020.According to the continuous oxygen dependence at 28 days after birth, VPI were divided into non BPD group and BPD group, and the risk factors of BPD in VPI were analyzed.Results:A total of 2 514 cases of VPI including 1 364 cases without BPD and 1 150 cases with BPD were enrolled.The incidence of BPD was 45.7%.The smaller the gestational age and weight, the higher the incidence of BPD( P<0.001). Compared with non BPD group, the average birth age, weight and cesarean section rate in BPD group were lower, and the incidence of male infants, small for gestational age and 5-minute apgar score≤7 were higher( P<0.01). In BPD group, the incidences of neonatal respiratory distress syndrome(NRDS), hemodynamically significant patent ductus arteriosus, retinopathy of prematurity, feeding intolerance, extrauterine growth restriction, grade Ⅲ~Ⅳ intracranial hemorrhage, anemia, early-onset and late-onset sepsis, nosocomial infection, parenteral nutrition-associated cholestasis were higher( P<0.05), the use of pulmonary surfactant(PS), postnatal hormone exposure, anemia and blood transfusion were also higher, and the time of invasive and non-invasive mechanical ventilation, oxygen use and total hospital stay were longer( P<0.001). The time of starting enteral nutrition, cumulative fasting days, days of reaching total enteral nutrition, days of continuous parenteral nutrition, days of reaching 110 kcal/(kg·d) total calorie, days of reaching 110 kcal/(kg·d) oral calorie were longer and the breastfeeding rate was lower in BPD group than those in non BPD group( P<0.001). The cumulative doses of amino acid and fat emulsion during the first week of hospitalization were higher in BPD group( P<0.001). Multivariate Logistic regression analysis showed that NRDS, invasive mechanical ventilation, age of reaching total enteral nutrition, anemia and blood transfusion were the independent risk factors for BPD in VPI, and older gestational age was the protective factor for BPD. Conclusion:Strengthening perinatal management, avoiding premature delivery and severe NRDS, shortening the time of invasive mechanical ventilation, paying attention to enteral nutrition management, reaching whole intestinal feeding as soon as possible, and strictly mastering the indications of blood transfusion are very important to reduce the incidence of BPD in VPI.
