Parkinson's disease （PD） is a chronic progressive neurodegenerative disorder primarily characterized by motor dysfunction. The main pathological features include the loss of dopaminergic neurons in the substantia nigra， abnormal aggregation of alpha-Synuclein （α-Syn）， and the formation of Lewy bodies. However， the exact mechanisms remain unclear. In recent years， the PD incidence has gradually increased， while current treatment methods are limited to symptom alleviation， incapable of halting disease progression， and prone to adverse effects， thus making it urgent to search for medicines effective for PD. Modern research indicates that the Kelch-like ECH-associated protein 1 （Keap1）/nuclear factor E₂ related factor 2 （Nrf2）/antioxidant response element （ARE） signaling pathway is closely related to oxidative stress， neuroinflammation， apoptosis， ferroptosis， and mitochondrial dysfunction， playing a crucial role in the pathophysiological development of PD. A large number of studies have further confirmed that traditional Chinese medicine （TCM） can regulate diseases through a holistic view of Syndrome differentiation and microscopic molecular pathways. With unique advantages， such as multiple targets， multiple pathways， and fewer adverse reactions， TCM provides a new strategy for PD treatment. This article elucidates the mechanism of the Keap1/Nrf2/ARE signaling pathway in the occurrence and development of PD， while summarizing the latest research on PD intervention by TCM monomers， active ingredients， and compounds， as well as acupuncture via the precise targeted regulation of the Keap1/Nrf2/ARE pathway， aiming to provide a reference for clinical medicine development to prevent and treat PD.

Based on the theory of collateral disease， the treatment of late-stage sequela of cerebrovascular disease is considered to be primarily associated with deficiency and obstruction of cerebral collaterals and dysfunction of the spirit mechanism. Therefore， the fundamental therapeutic principle is to unblock and supplement the brain collaterals. Clinically， the late-stage sequelae of cerebrovascular disease are classified into four patterns， which are malnourishment， deficiency-heat， stasis obstruction， and phlegm clouding of brain collaterals. These are treated respectively with Tiansui Tongqiao Decoction （填髓通窍汤） to supplement essence and nourish the brain through moistening， unblocking and supplementing， Qingnao Touluo Decoction （清脑透络汤） to enrich yin， regulate spirit， and unblock collaterals through clearing and penetrating， Yiqi Tongluo Decoction （益气通络汤） to tonify qi and resolve stasis while softening tendons and unblocking collaterals， and Xinrun Touqiao Beverage （辛润透窍饮） to unblock and tonify yin and yang while unblocking the collaterals through acrid-moistening medicinals. Flexible modification of prescriptions according to individual symptoms was applied， resulting in favorable therapeutic outcomes.

This article summarizes the clinical experience in diagnosing and treating narcolepsy based on the wei qi theory. The key pathogenesis of narcolepsy is considered to be the disharmony of wei qi. In the initial stage， lung， spleen， and kidney deficiency leads to insufficient generation and propulsion of wei qi. In the progressive stage， phlegm-damp and qi stagnation obstruct sanjiao （三焦）， while the interstice of flesh is unrelaxed， and the skin pores are occluded， causing sluggish circulation of wei qi. In the attack stage， pathogens obstruct the upper jiao （焦）， whereas pectoral qi fails to diffuse， and wei qi becomes constrained and blocked in the yin aspect， which may transform into wind or heat and bind with phlegm and stasis， resulting in sudden excessive sleep， cataplexy， dream disturbance， hallucinations， and sleep paralysis. Accordingly， a three-stage differentiation and treatment strategy is proposed， including reinforcing the root and strengthening wei qi in the initial stage with Peiben Shiwei Decoction （培本实卫汤）， resolving phlegm and unblocking the pathways to smooth the flow of wei qi in the progressive stage with Tongjiao Dawei Decoction （通焦达卫汤）， and diffusing wei qi， awakening the spirit， and opening the upper jiao in the attack stage with Xuanwei Xingshen Decoction （宣卫醒神汤）. Clinically， treatment should distinguish deficiency from excess， the primary from the secondary， administer staged and dynamic treatments， and make good use of light， clear， ascending， dispersing， acrid， and aromatic medicinals to restore the movement of wei qi， thereby providing a reference for differentiation and treatment of narcolepsy in traditional Chinese medicine.

Objective:To prepare mesothelin-loaded paclitaxel (PTX) phase change nanoparticles and evaluate their targeting effect and therapeutic effect on ovarian cancer.Methods:PTX-loaded phase-change nanoparticles PTX-NPs were prepared by the thin-film hydration method, and targeted mesothelin-loaded PTX phase-change nanoparticles Ab-PTX-NPs were prepared by attaching anti-mesothelin antibody to the nanoparticles using the biotin-affinity method. Zeta potential and particle size were determined by applying a zeta potential and a particle size analyzer, and the encapsulation rate and the amount of drug loading of PTX was measured by applying a UV spectrophotometer. Flow cytometry was used to detect the connectivity of anti-mesothelin antibody with PTX-NPs. The phase transition of Ab-PTX-NPs was induced by low-power focused ultrasound, and its ultrasonography imaging was observed; laser scanning confocal microscopy and flow cytometry were used to detect the targeting ability of Ab-PTX-NPs on ovarian cancer SKOV3 cells. The targeting and killing ability of Ab-PTX-NPs on ovarian cancer SKOV3 cells was observed by in vitro targeting assay and apoptosis detection assay. The ovarian cancer model of BALB/c nude mice was constructed to observe the distribution of Ab-PTX-NPs in vivo as well as the effects on blood biochemistry and important organs of nude mice. Results:Ab-PTX-NPs were successfully prepared with a zeta potential of -(8.37±2.71) mV, a diameter of (690.46±28.75) nm, an encapsulation rate of (88.2±4.4)% for PTX, a drug loading capacity of (27.3±0.9)%, and a linkage rate of (94.9±2.8)% between anti-mesothelin antibody and PTX-NPs. Low-intensity focused ultrasound could successfully induce phase transition of Ab-PTX-NPs to realize ultrasonography imaging, and 6 W was the optimal excitation power for low-intensity focused ultrasound. Ab-PTX-NPs showed excellent targeting and killing ability to SKOV3 cells, and the apoptosis and necrosis rate of SKOV3 cells in the Ab-PTX-NPs group reached 79.6%. In vivo imaging showed that the fluorescence intensity at the tumor site of nude mice in the Ab-PTX-NPs group was significantly higher than that in the PTX-NPs group. Biosafety assay showed that 15 d after Ab-PTX-NPs administration, the serum aspartate aminotransferase, alanine aminotransferase, creatine kinase, low-density lipoprotein, blood creatinine, and urea nitrogen concentrations of nude mice were (174.163±20.596)U/L, (33.297±2.573)U/L, (1 959.978±72.212)U/L, (22.033±5.030)μmol/L, (0.393±0.058)mmol/L, and (26.405±4.957)mmol/L, which were not significantly different from those of the phosphate buffer solution (PBS) group, the NPs group, and the PTX-NPs group. The organs such as the heart, the liver, the spleen, the lungs and the kidneys remained intact, and what was seen by the naked eye and microscope was similar with those of the PBS group, NPs group and PTX-NPs group. Conclusion:Ab-PTX-NPs were successfully prepared, which had good ovarian cancer targeting ability and killing effect and effectively reduced the toxicity of PTX.

Minimally conscious state （MCS） is at the edge between closed and open consciousness， but it still belongs to the category of "wind-strike block" syndrome. The basic pathogenesis of MCS is the obstruction of pathogenic qi， orifices closed and spirit hidden， with pathological factors including phlegm， fire， and blood stasis. Wind movement and water retention may also be present， and often leading to deficiency syndrome due to the exhaustion of qi， blood， yin， and yang at later stages. Treatment chooses Shexiang （Moschus） as the chief medicinal， emphasizing combination of medicinals and urgency of medication administration； the key therapeutic method is to open the orifices， with focuses on expelling pathogens and reinforcing healthy qi. For patients with severe phlegm or fire， use Xiaochengqi Decoction （小承气汤） to open the lower orifices， discharge heat and unblock the bowels， combined with Shexiang （Moschus） and Niuhuang （Bovis Calculus） to open the upper orifices， awaken the spirit and guide qi. For patients with turbid phlegm as the predominant， temporarily replace Shexiang （Moschus） with Baizhi （Angelicae dahuricae radix）， using Ditan Decoction （涤痰汤） to eliminate phlegm to open the orifices， when turbid phlegm gradually subsided， Shexiang （Moschus） could be added. For patients with blood stasis as the predominant， Tongqiao Huoxue Decoction （通窍活血汤） will be used to activate blood and open orifice， if the blood circulates， the endogenous wind will be calmed， the water will be induced， the orifices will open and the consciousness will restore. For patients with closed orifices and body deficiency， the treatment should open the orifices and reinforce healthy qi， and consider the root and branch simultaneously； qi deficiency syndrome can be addressed with Buyang Huanwu Decoction （补阳还五汤） to boost qi and reinforce healthy qi； yin deficiency syndrome can be treated with Shaoyao Gancao Decoction （芍药甘草汤） combined with Fengsui Pill （封髓丹） to nourish yin， soften sinews， and secure kidney essence； yang deficiency can be managed by using Dihuang Yinzi Decoction （地黄饮子） to enrich yin， supplement yang， and open the orifices.

Objective:To compare the clinical efficacy of percutaneous endoscopic interlaminar discectomy (PEID) and posterior small incision microdiscectomy (MD) in the treatment of recurrent lumbar disc herniation.Methods:A retrospective analysis was conducted on the data of 132 patients who underwent revision surgery for recurrent lumbar disc herniation at the same segment at Qilu Hospital of Shandong University between July 2012 and August 2022. The patients were treated with either PEID or MD. The PEID group consisted of 90 patients, including 51 males and 39 females, with a mean age of 42.7±11.3 years and a mean body mass index (BMI) of 23.7±3.4 kg/m 2. The surgical segments were L 4-5 in 38 cases and L 5S 1 in 52 cases. The primary surgeries included open discectomy in 7 cases, laminectomy with bone graft in 3 cases, MD in 35 cases, and PEID in 45 cases. The MD group consisted of 42 patients, including 30 males and 12 females, with a mean age of 41.2±12.6 years and a mean BMI of 24.3±4.7 kg/m 2. The surgical segments were L 4-5 in 19 cases and L 5S 1 in 23 cases. The primary surgeries included open discectomy in 2 cases, laminectomy with bone graft in 1 case, MD in 17 cases, and PEID in 22 cases. The visual analogue scale (VAS) scores for low back pain and leg pain, Oswestry disability index (ODI), immediate postoperative VAS score for surgical wound pain, intraoperative blood loss, surgical wound length, operation duration, length of hospital stay, and various complications before and after surgery were compared between the PEID and MD groups. Results:The operation duration in the PEID group was 81.7±11.3 min, that in the MD group was 85.2±9.5 min, but the difference was not statistically significant ( t=1.740, P=0.081). The intraoperative blood loss in the PEID group was 4.4±2.9 ml, the surgical wound length was 0.9±0.2 cm, and the length of hospital stay was 3.1±1.3 d, all significantly less than those in the MD group (26.6±10.3 ml, 3.4±1.1 cm, and 8.7±1.6 d, respectively), with statistically significant differences ( P<0.05). Both groups were followed up, with a mean follow-up duration of 24.4±5.5 months in the PEID group and 24.5±4.9 months in the MD group, and there was no statistically significant difference between the two groups ( t=0.101, P=0.920). Both the PEID and MD groups showed significant improvements in postoperative VAS scores for leg pain, VAS scores for low back pain, and ODI compared with preoperative values ( P<0.05). Additionally, the VAS score for surgical wound pain on the first postoperative day in the PEID group was 1.2±0.4, which was lower than that in the MD group (2.9±0.6), with a statistically significant difference ( t=19.261, P<0.001). The incidence rates of muscle weakness, postoperative sensory abnormalities, and dural tears in the PEID group were 12%(11/90), 27%(24/90), and 6%(5/90), respectively, significantly lower than those in the MD group [31%(13/42), 40%(17/42), and 33%(14/42), respectively], with statistically significant differences ( P<0.05). However, there were no statistically significant differences between the two groups in the incidence rates of recurrence, residual nucleus pulposus, spinal cord-like hypertension syndrome, subcutaneous wound infection, or intervertebral space infection ( P>0.05). No patients in either group developed retroperitoneal hematoma postoperatively. Conclusion:For patients with recurrent lumbar disc herniation after primary posterior surgery, PEID demonstrates equally excellent clinical efficacy compared with MD, with smaller surgical trauma and a lower incidence of complications.

Objective To compare the efficacy and safety of stellate ganglion block(SGB)with those of conventional western medication in the treatment of insomnia.Methods A computerized retrieval of academic papers concerning the clinical randomized controlled trials of SGB versus conventional western medication in the treatment of insomnia from the databases of PubMed,Embase,Cochrane Library,CNKI,Wanfang Data knowledge service platform,VIP database and CBM database was conducted.The retrieval time period was from the establishment of the database to June 13,2023.NoteExpress v3.5 software was used to make literature screening,Stata17.0 software was used to perform meta-analysis of the obtained data,TSA0.9.5.10 beta software was used to make sequential analysis,and GRADEpro was used to perform the grade classification.Results A total of 11 articles including 875 patients with insomnia were included in this analysis.Compared with the conventional western medication,SGB showed certain advantages in the following aspects:improving total clinical effectiveness(RR total=1.24,95％CI:1.16-1.32,P＜0.01),increasing the proportion of patients who could sleep for more than 3 hours after treatment(RR total=1.24,95％CI:1.09-1.41,P=0.001),increasing total sleep time(SMD=1.53,95％CI:0.89-2.16,P＜0.01),reducing sleep latency(MD=-14.08,95％CI:-18.72--9.43,P＜0.01),decreasing PSQI score(MD=-3.54,95％CI:-4.31--2.78,P＜0.01),and reducing the recurrence rate within 6 months(RR=0.19,95％CI:0.10-0.37,P＜0.01).However,the difference in the proportion of patients who could sleep for more than 6 hours after treatment between the two groups was not statistically significant(RR=1.31,95％CI:0.97-1.76,P=0.078).The traditional SGB therapy had a certain risk of adverse events,ultrasound-guided SGB therapy was much safer.Trial sequential analysis showed that the cumulative sample size of the effective rate crossed the conventional threshold and TSA threshold,the positive results had been obtained in advance although it did not reach RIS.The quality of evidence evaluated by GRADE for the sleep latency,PSQI and recurrence rate within 6 months was medium grade,and the quality for the remaining indexes was low grade.Conclusion Compared with conventional western medication for the treatment of insomnia,the effect of SGB in increasing the total response rate,the proportion of patients who get sleeping for more than 3 hours after treatment and the total sleep duration,in reducing sleep latency,PSQI score and recurrence rate within 6 months has gained some certain evidence supports.The SGB and conventional western medication have similar efficacy in improving the proportion of patients who get sleeping for more than 6 hours after treatment.The results of this study are stable and reliable,but the current level of evidence grade is lower,therefore,large-sample randomized controlled trials need to be conducted before its clinical efficacy can get further evidence-based support.

Objective:To compare the outcomes of ranibizumab and conbercept adjunct for pars plana vitrectomy (PPV) in the treatment of proliferative diabetic retinopathy (PDR).Methods:A prospective randomized case-control study. From June 2022 to December 2023, 90 cases (90 eyes) of PDR patients diagnosed through ophthalmic examination at Department of Ophthalmology of Gansu Provincial Hospital were included in the study. All patients underwent the best corrected visual acuity (BCVA), intraocular pressure, B-mode ultrasound, and optical coherence tomography (OCT) examinations. The central macular thickness (CMT) was measured using an OCT instrument. The patients were randomly divided into a intravitreal injection of ranibizumab group (monoclonal-antibody group) and a intravitreal injection of conbercept group (fusion-protein group) using a random number table method, with 45 cases (45 eyes) in each group. Two groups of patients were intravitreal injected with 10 mg/ml ranibizumab or conbercept 0.05 ml, respectively. A standard 23G PPV was performed through the flat part of the ciliary body 3-7 days after intravitreal injection. Relevant examinations were performed using the same equipments and methods as before surgery at postoperative 1 week, 1, 3, 6, and 12 months. The PPV time, intraoperative use of intraocular electrocoagulation, incidence of iatrogenic retinal breaks, and sterile air or silicone oil tamponade rate in the vitreous cavity, the postoperative changes of BCVA and CMT, and incidence of complications were compared between two groups. Independent sample t test was used for inter group comparison. Results:The intraoperative utilization rate of intraocular electrocoagulation in the monoclonal-antibody group was higher than that in the fusion-protein group, and the difference was statistically significant ( χ2=3.876, P<0.05). There were no statistically significant differences in the PPV time ( t=0.152), intraoperative bleeding rate ( χ2=0.800), incidence of iatrogenic retinal breaks ( χ2=1.975), and sterile air and silicone oil tamponade rate in the vitreous cavity ( χ2=1.607, 1.553) between the two groups ( P>0.05). There were no statistically significant differences in early and late postoperative vitreous hemorrhage ( χ2=1.235, 2.355), and re-PPV ( χ2=2.355) between two groups ( P>0.05). The BCVA of the fusion-protein group was significantly better than that of the monoclonal-antibody group at postoperative 3 months, and the difference was statistically significant ( t=2.428, P<0.05). The CMT of the fusion-protein group was lower than that in the monoclonal-antibody group at postoperative 1 week, and the difference was statistically significant ( t=2.739, P<0.05). None of the patients experienced endophthalmitis, retinal artery occlusion, or severe cardiovascular events after surgery. Conclusion:Compared with intravitreal injection of ranibizumab before PPV, intravitreal injection of conbercept before PPV in PDR patients can shorten the surgical time, reduce intraoperative bleeding rate, lower the rate of electrocoagulation and intraocular tamponade, and incidence of iatrogenic retinal breaks, and improve the visual acuity.

Objective To construct a quality evaluation index system for non-medical technical services in public hospitals,aiming to provide a more scientific and feasible basis for evaluating patient service quality.Methods Based on literature research,the SERVQUAL theory was used to preliminarily formulate a comprehensive and full-cycle evaluation index for patient service quality.The final evaluation index system was determined through expert consultation,and the Analytic Hierarchy Process was used to determine the weights of the evaluation indices.Results The questionnaire response rates for the two rounds of expert consultation were both 100％.The authority coefficients of the experts were 0.82 and 0.80,respectively,indicating a high level of expert authority.The Kendall's W coefficient increased from 0.088 to 0.107 between the two rounds,and the difference was statistically significant (P<0.001),indicating good consistency of expert opinions.The consistency results of each judgment matrix were less than 0.1,passing the consistency test.The final evaluation index system consisted of six primary indicators (tangibility,reliability,responsiveness,assurance,empathy,and continuity) and 33 secondary indicators.Conclusion The selection of evaluation indicators revolves around the core service processes of outpatient,inpatient,and other hospital services,focusing on key elements at various critical junctures that influence patient experience.The evaluation indicators aim to guide hospitals to improve not only essential needs but also desired improvements in service quality,thus promoting the continuous enhancement of hospital services.
