Due to factors such as an aging population, the Hospital Authority(HA) of Hong Kong is facing a contradiction between limited health resource supply and continuously increasing demand. In order to effectively address challenges, the HA prompted three measures to bridging the demand-supply gap. The HA relied on its management system advantages to continuously increase its capital construction to enhance the service capacity of public health institutions; transformed service delivery mode so as to improve the experience, quality, and efficiency of service delivery; established cooperation with private service providers and communities to shunt population health demand. The practices of HA can provide reference for public hospitals and their sponsors in other regions of China.

Objective To explore the application value of telmisartan combined with calcium dobesilate in patients with non-dipper hypertension complicated with type 2 diabetes mellitus(T2DM).Methods A total of 260 patients with non-dipper hypertension complicated with T2DM in the endocrinology department of our hospital were selected in this study from January 2021 to December 2022.All the patients were randomly divided into telmisartan group(Tel,n=110)and telmisartan+calcium dobesilate group(Tel+Cal-dob,n=150).The blood pressure level,blood pressure rhythm changes,brachial flow mediated dilatation(FMD),carotid radial pulse wave velocity(crPWV),vasomotor factors[nitric oxide(NO),endothelin-1(ET-1),vascular endothelial growth factor(VEGF)]and the incidence of adverse reactions were compared between the two groups.Results There was no significant difference in general data and biochemical indexes between the two groups(P>0.05).After 3,6 and 12 months of treatment,the FMD and NO were higher,while the dSBP,dDBP,24 hSBP,24 hDBP,nSBP,nDBP,crPWV,ET-1 and VEGF were lower than before treatment in both groups(P<0.05).After 3,6 and 12 months of treatment,the FMD and NO were higher,while dSBP,dDBP,24 hSBP,24 hDBP,nSBP,nDBP,crPWV,ET-1 and VEGF were lower in Tel+Cal-dob group than in Tel group(P<0.05).After 3,6 and 12 months of treatment,the conversion rates of dipper blood pressure were higher in Tel+Cal-dob groupthan in Tel group(P<0.05).There was no significant difference in the incidence of adverse effects between the two groups(P>0.05).Conclusion Telmisartan combined with calcium dobesilate is effective in the treatment of patients with non-dipper hypertension complicated with T2DM.

This study was designed to investigate the effect of hypoxia on preeclampsia(PE)by modulating the Src/Siglec-6/SHP2 signaling pathway in the cytoplasm of trophoblast cells.Mouse model of PE was established in normal control and Siglec-6 knockdown mice by L-NAME administration,with aims of studying the changes in vascular diameter of spiral arteries in vivo and examining the expression levels of Siglec-6,p-Src,p-Shp2 and p-ERK1/2 proteins in mouse uterine vascular tissues.While,the effect of Src/Siglec-6/SHP2 on the invasive proliferation of trophoblast cells was explored by culturing human chorionic trophoblast cells HTR-8/SVneo with hypoxia in vitro.In vivo experimental assays showed that the diameter of spiral arteries was reduced in the Siglec-6 knockdown group of mice,and the expression levels of Siglec-6,p-Src,p-SHP2 and p-ERK1/2 proteins were significantly reduced.In vitro hypoxic HTR-8/SVneo cell model results revealed that Siglec-6 overexpression could promote trophoblast cell invasion and proliferation by regulating p-Src,p-SHP2,p-ERK1/2,MMP2,P53 and P21.While,suppression of Src and SHP2 eliminated Siglec-6 overexpression-mediated Siglec-6,p-Src,p-SHP2 and p-ERK1/2 expression,and inhibited the ability of Siglec-6 overexpression to mediate trophoblast invasion and proliferation.Taken together,Siglec-6 plays an important role in preeclampsia,and can alleviate preeclampsia by promoting trophoblast invasion and proliferation through the Src/SHP2 signalling pathway.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Mild traumatic brain injury (mTBI) is a traumatic disease that has transient impairment of consciousness and memory function after an external force to the head with basically normal neurological function and neuroimaging examination results. At present, research on mTBI is insufficient, resulting from early diagnosed difficulty of mTBI patients (due to mild clinical manifestations) and not suitable traditional diagnosis and treatment evaluation methods. This article reviews the research progress in the pathogenesis, auxiliary examinations, treatment principles and related diseases of mTBI, aiming to provide new theoretical basis for diagnosis and treatment of mTBI.

【Objective】 To explore the influence of common methods of reducing non-viral nucleic acid on the abundance of plasma virus group. 【Methods】 Three kinds of library construction, five kinds of centrifugation conditions, two kinds of filters, four kinds of enzymes and four concentrations of chloroform were used to treat plasma samples added quantitatively 2.16 mL of pseudorabies virus(PRV) and 2.16 mL of porcine parvovirus(PPV). A total of 21.6 mL of plasma samples were processed, including 54 samples. Subsequently, nucleic acid was extracted, mitochondrial DNA(mtDNA) and two viruses were quantitated, the library of the next generation sequencing was constructed, Illumina NovaSeq 6000 was used for the next generation sequencing. The sequencing data were compared with Kraken Py 2.0 software, and the species annotation analysis was conducted. The corresponding species classification information of each segment was obtained to analyze the impact of different reducing non-viral nucleic acid methods on the relative abundance of microorganisms and two indicator viruses. 【Results】 After sequencing by Illumina NovaSeq 6000, 306.27 GB raw data and 193.17 GB clean data were obtained, with Q20>90%, Q30>85%, Error Rate of 0.03%, and average GC Content of 45.02%. The DNA library construction process significantly increased the proportion of microbial sequences and the PRV abundance [(91.8±0.5)%](P<0.05); RNA library construction and combined library construction can increase the abundance of Pestivirus, an RNA virus, and the PRV abundance was(17.7±3.3)% and(8.1±1.5)% respectively. The Ct value of mtDNA was increased and the proportion of human sequence decreased to less than(89.5±1)%, while the proportion of microbial sequence increased to (2.4±0.03)% after treatment of five centrifugation conditions(P<0.05); After centrifugation at 4℃, 100 g, 30 min, the PRV abundance was increased to (40.6±6)%, and centrifugation at 4℃, 4 000 g, 45 min reduced the PRV abundance to (4.1±0.01)%(P<0.05). Both of 0.22-μm filter and 0.45-μm filter increased the Ct value of mtDNA to above 25.56±0.13, decreased the proportion of human sequence to less than (86.1±0.6)%, increased the proportion of microbial sequence to (3.1±0.1)% and (3.4±0.2)%, and decreased the PRV abundance to (1.6±0.3)% and (4.1±0.7)%(P<0.05), while there was no statistical difference in the effect on PPV concentration and abundance. DNase Ⅰ and Benzonase increased the Ct value of PPV to 25.65±0.06 and 25.36±0.45, decreased the proportion of human sequence to (81.7±5.6)% and (72.8±6.7)%, and increased the proportion of microbial sequence and PRV abundance to (11.0±4.1)% and (16.1±4.7)%, (55.8±2.3)% and (39.0±8.9)%, respectively(P<0 05); After treatment with RNase A, the Ct value of PRV increased to 25.20±0.11, and the human sequence proportion decreased to (85.4±5.6)%(P<0 05); Lysozyme had no effect on removing non-viral nucleic acid. The chloroform of 1%, 5%, 10% and 20% increased Ct value of PRV and mtDNA to no less than 27.17±0.21 and 25.68±0.04; Only 10% chloroform increased the proportion of microbial sequences to (3.1±1.2)%(P<0.05); The abundance of PRV with 1% and 5% chloroform treatment was increased to (48.7±13.3)% and (42.1±5.5)%(P<0.05), while 10% and 20% chloroform reduced PRV abundance to (1.0±0.5)% and (3.4±2.8)%(P<0.05). There was no statistical difference in the effect of chloroform with four contents on PPV abundance. 【Conclusion】 Centrifugation at 4℃, 5 000 g, 10 min is suitable for increasing the overall abundance of virus, and centrifugation at 4℃, 100 g, 30 min is suitable for increasing the content of virus similar to PRV. 0.45-μm filter, DNase Ⅰ, Benzonase and low concentration chloroform can effectively reduce the proportion of non-viral nucleic acid sequence in plasma to increase the abundance of the indicated virus group. Thus, the enrichment effect of plasma meta-virome is closely related to the nature of the virus, and the appropriate virus enrichment method should be selected according to the research purpose to establish the corresponding enrichment strategy.

Objective:To analyze the risk factors for hospital acquired pulmonary infections in elderly lung cancer patients during chemotherapy, and construct a prediction model to provide personalized guidance for clinical nursing work.Methods:Using convenience sampling, clinical case data of 405 elderly lung cancer patients who underwent chemotherapy at the First Affiliated Hospital of Zhengzhou University from January 2021 to December 2022 were collected. A total of 226 patients from January to December 2021 were selected as the modeling group, and 179 patients from January to December 2022 were selected as the validation group. In the modeling group, the patients were divided into two groups based on whether or not they had hospital acquired pulmonary infection, including the hospital acquired pulmonary infection group and the non-hospital acquired pulmonary infection group. Single factor analysis and multivariate Logistic regression analysis were used to determine the risk factors for hospital acquired pulmonary infection in elderly lung cancer patients during chemotherapy. A risk prediction model for hospital acquired pulmonary infection in elderly lung cancer patients during chemotherapy was constructed based on the results of multivariate analysis. The area under the receiver operating characteristic (ROC) curve was used to evaluate the predictive performance of the prediction model, and a calibration map was drawn for consistency testing. The prediction model was validated in the validation group to evaluate its predictive performance.Results:The incidence of hospital acquired pulmonary infection in the modeling group was 14.6% (33/226). The results of multivariate Logistic regression analysis showed that basic diseases, tumor-node-metastasis (TNM) staging, neutropenia, and invasive procedures were risk factors for hospital acquired pulmonary infections in elderly lung cancer patients undergoing chemotherapy ( P<0.05). Based on this result, a prediction model was constructed, with an area under the ROC curve of 0.832 [95% CI (0.764, 0.900) ] in the modeling group and 0.759 [95% CI (0.695, 0.824) ] in the validation group. The calibration curves of the modeling and validation groups showed a good coincidence between the predicted results and the actual results. Conclusions:Basic diseases, neutropenia, invasive procedures, and advanced stages of tumors are risk factors for hospital acquired pulmonary infections in elderly lung cancer patients undergoing chemotherapy. For high-risk patients, individualized intervention should be carried out as soon as possible to reduce the incidence of hospital acquired pulmonary infection.

OBJE CTIVE To establish the finger prints for Yinhuang solution for inhalation and determine the contents of neochlorogenic acid ，chlorogenic acid and cryptochlorogenic acid simultaneously. METHODS Using baicalin as reference ，the fingerprints of Yinhuang solution for inhalation were established by high performance liquid chromatography （HPLC）. Relative correction factors of neochlorogenic acid and cryptochlorogenic acid were calculated by slope correction method ，using chlorogenic acid as reference ；the contents of them were calculated according to relative correction factor. The results of quantitative analysis of multi-components by single marker （QAMS）were compared with those of external standard method （ESM）. RESULTS There were 18 common peaks in the fingerprints of 10 batches of Yinhuang solution for inhalation ，and their similarities with reference fingerprint were higher than 0.90. A total of 7 common peaks were identified as baicalin ，neochlorogenic acid ，chlorogenic acid ， cryptochlorogenic acid ，isochlorogenic acid B ，3，5-di-O-caffeoylquinic acid and 4，5-di-O-caffeoylquinic acid. The linear range of neochlorogenic acid ，chlorogenic acid and cryptochlorogenic acid were 0.025 0-1.247 4 μg（r＝0.999 7），0.039 3-1.178 7 μg（r＝ 0.999 9），0.031 6-1.184 1 μg（r＝0.999 9），respectively.

Relative correction factors of neochlorogenic acid and cryptochlorogenic acid were 1.068 and 1.233. The contents of neochlorogenic acid and cryptochlorogenic acid determined by QAMS method were 0.301 8-0.386 3 and 0.262 5-0.362 5 mg/mL， respectively. The contents of neochlorogenic acid ，chlorogenic acid and cryptochlorogenic acid by ESM were 0.302 6-0.387 2， 0.231 0- 0.334 0，0.261 6-0.361 3 mg/mL，respectively. The deviations of the content determination results of the two methods（except for chlorogenic acid ）were both not higher than 0.20％. CONCLUSIONS Established HPLC fingerprints are stable and feasible. Established QAMS method is accurate and rapid. HPLC fingerprint combined with QAMS can be used for the quality control for Yinhuang solution for inhalation ．

ObjectiveTo investigate the feasibility of apical sodium-dependent bile salt transporter (ASBT) and asialoglycoprotein receptor (ASGPR) in the design of oral liver-targeting preparations for the treatment of hepatic alveolar echinococcosis (HAE) by measuring the expression of ASBT and ASGPR. MethodsA total of 18 male Sprague-Dawley rats were selected, among which 10 were used to establish a model of HAE (HAE group) and 8 were used as controls (normal group). Immunofluorescence assay, Western blotting, and quantitative real-time PCR were used to measure the expression distribution, protein expression level, and mRNA expression level of ASBT in the ileal tissue of HAE model rats and normal rats; the same methods were used to measure the expression level of ASGPR in the non-diseased liver tissue and the marginal zone of liver tissue lesion of HAE model rats and the liver tissue of normal rats. The t-test was used for comparison of normally distributed continuous data between two groups; a one-way analysis of variance was used for comparison between three groups, and the least significant difference t-test was used for comparison between two groups. ResultsThe results of immunofluorescence assay, Western blotting, and quantitative real-time PCR showed that compared with the normal group, the HAE group had significantly upregulated expression of ASBT in the ileal tissue (t=5309, 4.110, and 28.060, all P＜0.05) and a significantly higher expression level of ASGPR (the closer to the lesion, the higher the expression) (F=110666, 128.201, and 143.879, all P＜0.001). ConclusionASBT and ASGPR can be used as potential mediated receptors for oral liver-targeting preparations for HAE, which provides a theoretical basis for the design of oral liver-targeting preparations for the treatment of HAE.

The development of information technology in the medical industry is accelerating the construction of 3-level rehabilitation networks centering on community-based rehabilitation, which is based on the Internet and in combination with the Internet of things(IOT). A municipal rehabilitation hospital cooperated with the health centers of sub-district communities in the city to build a remote rehabilitation network based on IOT technology, for rehabilitation training of community stroke patients. The two sides worked out a cooperation scheme on project management, designed and built a remote community rehabilitation management model. Under the remote monitoring and equipment data IOT, the medical team of the municipal rehabilitation hospital could formulate the therapeutic plan according to the immediately obtained relevant functional evaluation data, and the medical team of the community health service center was responsible for the implementation of the plan. Fifty-three patients in the experimental group received the training of remote lower limb intelligent feedback system based on IOT together with routine rehabilitation training. After 8 weeks of treatment, the functional evaluation data of the two groups were improved in varying degrees( P< 0.05), but the improvement of the experimental group was significantly better than that of the control group( P < 0.05). Remote rehabilitation under the construction path of remote rehabilitation network based on IOT technology could significantly promote the improvement of post-functional rehabilitation of community stroke patients. This study can provide reference for the construction of three-level remote rehabilitation networks based on IOT and the implementation of home-based remote rehabilitation therapy in the future.
