ObjectiveMicrotube associated protein-2 （MAP-2）， alpha-tubulin （α-tubulin）， and synaptophysin （SYP） are important proteins in neuronal signal communication. This paper observed the effects of modified Zhigancao Tang on the expression of serum α-Synuclein （α-Syn） and its oligomers， MAP-2， α-tubulin， and SYP of patients with liver and kidney deficiency of Parkinson's disease （PD）， analyzed their correlation， and evaluated the therapeutic effect of modified Zhigancao Tang in patients with liver and kidney deficiency of PD based on α-Syn transmission pathway mediated by neuronal communication in vivo. MethodsA total of 60 patients with PD who met the inclusion criteria were randomly divided into a treatment group （30 cases） and a control group （30 cases）. Both groups were treated on the basis of PD medicine， and the treatment group was treated with modified Zhigancao Tang. Both groups were treated for 12 weeks. The changes in UPDRS score， TCM syndrome score， and expression of serum α-Syn and its oligomers， MAP-2， α-tubulin， and SYP were observed before and after 12 weeks of treatment in each group. The correlation between the above-mentioned serum biological indexes and the levels of serum α-Syn and its oligomers was analyzed. ResultsAfter treatment， the TCM syndrome score， UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ score of the treatment group were significantly decreased （P<0.05， P<0.01）. The UPDRS score， UPDRS-Ⅱ score， and UPDRS-Ⅲ scores in the treatment group were significantly decreased compared with those in the control group after treatment （P<0.05）. After treatment， the total effective rate of the control group was 63.3% （19/30）， and that of the treatment group was 86.7% （26/30）. The clinical effect of the observation group was better than the control group （Z=-2.03， P<0.05）. The total effective rate of the observation group was better than that of the control group， and the difference was statistically significant （χ²=5.136， P<0.05）. After treatment， the oligomer level of serum α-Syn and MAP-2 level in the treatment group were significantly decreased （P<0.05， P<0.01）. The levels of serum α-Syn and its oligomers， as well as α-tubulin in the treatment group， were significantly decreased compared with those in the control group after treatment （P<0.05， P<0.01）. Serum α-Syn was correlated with serum MAP-2 and α-Syn oligomer in patients with PD （P<0.05， P<0.01） but not correlated with serum SYP . Serum α-Syn oligomers of patients with PD were correlated with serum MAP-2 and α-tubulin （P<0.05， P<0.01） but not correlated with serum SYP level. Serum SYP of patients with PD was correlated with serum MAP-2 （P<0.05）. ConclusionModified Zhigancao Tang has a therapeutic effect on patients with liver and kidney deficiency of PD by inhibiting the production of α-Syn oligomers and intervening α-Syn microtubule transport pathway in vivo.

ObjectiveExisting artificial vision devices can be divided into two types: implanted devices and extracorporeal devices, both of which have some disadvantages. The former requires surgical implantation, which may lead to irreversible trauma, while the latter has some defects such as relatively simple instructions, limited application scenarios and relying too much on the judgment of artificial intelligence (AI) to provide enough security. Here we propose a system that has voice interaction and can convert surrounding environment information into tactile commands on head and neck. Compared with existing extracorporeal devices, our device can provide a larger capacity of information and has advantages such as lower cost, lower risk, suitable for a variety of life and work scenarios. MethodsWith the latest remote wireless communication and chip technologies, microelectronic devices, cameras and sensors worn by the user, as well as the huge database and computing power in the cloud, the backend staff can get a full insight into the scenario, environmental parameters and status of the user remotely (for example, across the city) in real time. In the meanwhile, by comparing the cloud database and in-memory database and with the help of AI-assisted recognition and manual analysis, they can quickly develop the most reasonable action plan and send instructions to the user. In addition, the backend staff can provide humanistic care and emotional sustenance through voice dialogs. ResultsThis study originally proposes the concept of “remote virtual companion” and demonstrates the related hardware and software as well as test results. The system can not only achieve basic guide functions, for example, helping a person with visual impairment to shop in supermarkets, find seats at cafes, walk on the streets, construct complex puzzles, and play cards, but also can meet the demand for fast-paced daily tasks such as cycling. ConclusionExperimental results show that this “remote virtual companion” is applicable for various scenarios and demands. It can help blind people with their travels, shopping and entertainment, or accompany the elderlies with their trips, wilderness explorations, and travels.

Objective:To investigate the current status of endoscopic treatment for gastroesophageal varices in portal hypertension in China, and to provide supporting data and reference for the development of endoscopic treatment.Methods:In this study, initiated by the Liver Health Consortium in China (CHESS), a questionnaire was designed and distributed online to investigate the basic condition of endoscopic treatment for gastroesophageal varices in portal hypertension in 2022 in China. Questions included annual number and indication of endoscopic procedures, adherence to guideline for preventing esophagogastric variceal bleeding (EGVB), management and timing of emergent EGVB, management of gastric and isolated varices, and improvement of endoscopic treatment. Proportions of hospitals concerning therapeutic choices to all participant hospitals were calculated. Guideline adherence between secondary and tertiary hospitals were compared by using Chi-square test.Results:A total of 836 hospitals from 31 provinces (anotomous regions and municipalities) participated in the survey. According to the survey, the control of acute EGVB (49.3%, 412/836) and the prevention of recurrent bleeding (38.3%, 320/836) were major indications of endoscopic treatment. For primary [non-selective β-blocker (NSBB) or endoscopic therapies] and secondary prophylaxis (NSBB and endoscopic therapies) of EGVB, adherence to domestic guideline was 72.5% (606/836) and 39.2% (328/836), respectively. There were significant differences in the adherence between secondary and tertiary hospitals in primary prophylaxis of EGVB [71.0% (495/697) VS 79.9% (111/139), χ2=4.11, P=0.033] and secondary prophylaxis of EGVB [41.6% (290/697) VS 27.3% (38/139), χ2=9.31, P=0.002]. A total of 78.2% (654/836) hospitals preferred endoscopic therapies treating acute EGVB, and endoscopic therapy was more likely to be the first choice for treating acute EGVB in tertiary hospitals (82.6%, 576/697) than secondary hospitals [56.1% (78/139), χ2=46.33, P<0.001]. The optimal timing was usually within 12 hours (48.5%, 317/654) and 12-24 hours (36.9%, 241/654) after the bleeding. Regarding the management of gastroesophageal varices type 2 and isolated gastric varices type 1, most hospitals used cyanoacrylate injection in combination with sclerotherapy [48.2% (403/836) and 29.9% (250/836), respectively], but substantial proportions of hospitals preferred clip-assisted therapies [12.4% (104/836) and 26.4% (221/836), respectively]. Improving the skills of endoscopic doctors (84.2%, 704/836), and enhancing the precision of pre-procedure evaluation and quality of multidisciplinary team (78.9%, 660/836) were considered urgent needs in the development of endoscopic treatment. Conclusion:A variety of endoscopic treatments for gastroesophageal varices in portal hypertension are implemented nationwide. Participant hospitals are active to perform emergent endoscopy for acute EGVB, but are inadequate in following recommendations regarding primary and secondary prophylaxis of EGVB. Moreover, the selection of endoscopic procedures for gastric varices differs greatly among hospitals.

Objective:To observe the changes of pelvic floor structure and function in female vaginal laxity after CO 2 fractional laser transvaginal treatment. Methods:This study reviewed the improvement of pelvic floor structure and function after CO 2 fractional laser transvaginal treatment in 28 female patients [aged 26-59 (37.5±8.3) years] with vaginal laxity syndrome seen at the Department of Dermatology, the First Affiliated Hospital of Air Force Medical University from March 2020 to November 2021. A total of 28 female patients with vaginal laxity syndrome underwent intravaginal treatment by CO 2 fractional laser instrument once/month for 3 times. The clinical efficacy and safety were evaluated according to the pre- and post-treatment transverse vaginal diameter, FSFI score of female sexual function, VHIS score of vaginal environment, vaginal tactile imaging system (VTI), pelvic ultrasound and MRI, tissue biopsy, patient satisfaction, pain score, and postoperative adverse effects. Results:Twenty-one of the twenty-eight female patients with vaginal laxity syndrome showed significant improvement in symptoms related to vaginal laxity syndrome after intravaginal treatment with CO 2 fractional laser therapy. All patients showed improvement in all indexes before and 1 month after treatments the mean vaginal transverse diameter decreased from (3.00±0.39) fingers to (2.71±0.40) fingers ( P<0.05), VHIS increased from (17.12±3.97) to (21.69±3.61) ( P<0.05), FSFI score improved from (23.11±3.70) to (27.43±5.33) ( P<0.05), and VTI examination showed that vaginal muscle strength and elasticity were improved to different degrees, and there was a statistical difference compared with that before treatment (total contractility of the anterior vaginal wall: t=26.23, P<0.001; total contractility of posterior vaginal wall: t=39.02, P<0.001; the mean contractility of the anterior vaginal wall: t=17.92, P<0.001; the mean contractility of the posterior vaginal wall: t=22.57, P<0.001). At the same time, questionnaire score of international consultation on incontinent questionnaire short form (ICI-Q-SF scale) of 13 patients with combined mild to moderate stress urinary incontinence showed a statistically significant decrease compared with those before treatment (8.97±2.99 before treatment and (7.18±1.79) one month after treatment; t=2.792, P<0.01). Pelvic ultrasound and magnetic resonance examination indicated a tightening of the vaginal wall structure, and pelvic ultrasound observed a significant decrease in bladder neck mobility and a significant decrease in vesicourethral rotation angle. Vaginal tissue biopsy indicated an increase in the thickness of the vaginal mucosa and an increase in the number and more regular arrangement of collagen fibers after treatment. All patients had high treatment satisfaction and there were no adverse effects such as infection and bleeding during the treatment. Conclusions:Transvaginal CO 2 fractional laser treatment can improve the pelvic floor structure and function around the vagina, treat female vaginal laxity syndrome, stress urinary incontinence and female sexual dysfunction, with significant clinical efficacy and good safety.

Background::A phase II trial on recombinant human tenecteplase tissue-type plasminogen activator (rhTNK-tPA) has previously shown its preliminary efficacy in ST elevation myocardial infarction (STEMI) patients. This study was designed as a pivotal postmarketing trial to compare its efficacy and safety with rrecombinant human tissue-type plasminogen activator alteplase (rt-PA) in Chinese patients with STEMI.Methods::In this multicenter, randomized, open-label, non-inferiority trial, patients with acute STEMI were randomly assigned (1:1) to receive an intravenous bolus of 16 mg rhTNK-tPA or an intravenous bolus of 8 mg rt-PA followed by an infusion of 42 mg in 90 min. The primary endpoint was recanalization defined by thrombolysis in myocardial infarction (TIMI) flow grade 2 or 3. The secondary endpoint was clinically justified recanalization. Other endpoints included 30-day major adverse cardiovascular and cerebrovascular events (MACCEs) and safety endpoints.Results::From July 2016 to September 2019, 767 eligible patients were randomly assigned to receive rhTNK-tPA ( n = 384) or rt-PA ( n = 383). Among them, 369 patients had coronary angiography data on TIMI flow, and 711 patients had data on clinically justified recanalization. Both used a –15% difference as the non-inferiority efficacy margin. In comparison to rt-PA, both the proportion of patients with TIMI grade 2 or 3 flow (78.3% [148/189] vs. 81.7% [147/180]; differences: –3.4%; 95% confidence interval [CI]: –11.5%, 4.8%) and clinically justified recanalization (85.4% [305/357] vs. 85.9% [304/354]; difference: –0.5%; 95% CI: –5.6%, 4.7%) in the rhTNK-tPA group were non-inferior. The occurrence of 30-day MACCEs (10.2% [39/384] vs. 11.0% [42/383]; hazard ratio: 0.96; 95% CI: 0.61, 1.50) did not differ significantly between groups. No safety outcomes significantly differed between groups. Conclusion::rhTNK-tPA was non-inferior to rt-PA in the effect of improving recanalization of the infarct-related artery, a validated surrogate of clinical outcomes, among Chinese patients with acute STEMI.Trial registration::www.ClinicalTrials.gov (No. NCT02835534).

Objective:To investigate whether cavitation induced by ultrasound stimulated perfluorobutane microbubbles can enhance the therapeutic effect of colchicine and reduce its side effects on acute gouty arthritis (AGA) in rats.Methods:The AGA rat model was established by injection of monosodium urate (MSU) crystals. The rats were randomly divided into 6 groups (A: blank control group, B: model control group, C: cavitation group, D: standard concentration drug group, E: low concentration drug cavitation group, F: standard concentration drug cavitation group) according to whether they were given different doses of colchicine. The area under the curve (AUC) of contrast-enhanced ultrasound (CEUS) was calculated at 7 h and 8 h after MSU injection to compare the effect of cavitation on ankle blood perfusion. The symptoms of AGA were evaluated according to the degree of ankle swelling and gait score at 24 h. The infiltration of neutrophils was detected by HE staining, and the inflammatory response was analyzed by detecting the level of interleukin-1β (IL-1β) in plasma. Vascular dilatation was analyzed by detecting the concentration of endothelial nitric oxide synthase (eNOS). The degree of adverse reactions in each group was analyzed by gastrointestinal reaction score.Results:The CEUS blood perfusion and AUC values of the three groups with cavitation (groups C, E and F) were significantly higher than those of the non-cavitation groups (groups A, B and D) (all P<0.05). Compared with group D, there were no significant differences in the degree of ankle swelling, gait score, and plasma IL-1β level in group E (all P>0.05), but the plasma eNOS concentration was higher and the incidence of gastrointestinal reactions was significantly lower in group E (all P<0.05). Compared with group D, the degree of ankle swelling and gait score in group F were decreased, and HE staining showed that the degree of synovial infiltration of neutrophils in the ankle joints of AGA rats in group F was lighter (all P<0.05), but there was no significant difference in plasma IL-1β level and the incidence of gastrointestinal reactions between group D and group F (all P>0.05). Conclusions:The cavitation of perfluorobutane microspheres stimulated by ultrasound can enhance the blood perfusion of the ankle joint of AGA rats, enhance the therapeutic effect of local colchicine, and help to reduce the dosage of colchicine and its side effects.

As one of the main diseases leading to end-stage renal disease, steroid-resistant nephrotic syndrome(SRNS) can cause serious complications such as infection. Without effective control, this disease can further lead to the malignant development of the renal function, bringing serious social and economic burdens. As previously reported, the formation of SRNS is mostly related to the podocyte injury in the body, i.e., the injury of glomerular visceral epithelial cells. Phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt) signaling pathway, nuclear transcription factor-κB(NF-κB) signaling pathway, mammalian target of rapamycin(mTOR)/adenosine monophosphate(AMP)-activated protein kinase(AMPK), transforming growth factor(TGF)-β1/Smads, and other signaling pathways are classical signaling pathways related to podocyte injury. By regulating the expression of signaling pathways, podocyte injury can be intervened to improve the adhesion between podocyte foot processes and glomerular basement membrane and promote the function of podocytes, thereby alleviating the clinical symptoms of SRNS. Through the literature review, traditional Chinese medicine(TCM) has unique advantages and an important role in intervening in podocyte injury. In the intervention in podocyte injury, TCM, by virtue of multi-target and multi-pathway role, can regulate and intervene in podocyte injury in many ways, alleviate the clinical symptoms of SRNS, and interfere with the progress of SRNS, reflecting the unique advantages of TCM. On the other hand, TCM can directly or indirectly inhibit podocyte injury by regulating the above signaling pathways, which can not only promote the effect of hormones and immunosuppressants and shorten the course of treatment, but also reduce the toxic and side effects caused by various hormones and immunosuppressants to exert the advantages of small side effects and low price of TCM. This article reviewed TCM in the treatment of SRNS by interfering with podocyte injury-related signaling pathways and is expected to provide a reference for the in-depth study of TCM in the treatment of SRNS, as well as a theoretical basis and a new direction for the clinical application of TCM to shorten the course of treatment of SRNS and delay the progression to end-stage renal disease.
