OBJECTIVE: To compare the clinical efficacy of herbal cake-separated moxibustion at Baliao acupoints combined with western medication versus western medication alone in treating erectile dysfunction (ED) with kidney deficiency and blood stasis. METHODS: A total of 108 ED patients were randomly divided into a combination group (54 cases, 2 cases dropped out) and a western medication group (54 cases, 1 case was eliminated, 2 cases dropped out). The western medication group received oral tadalafil tablets 5 mg a time, once daily. The combination group received additional herbal cake-separated moxibustion at Baliao acupoints (Shangliao [BL31], Ciliao [BL32], Zhongliao [BL33], Xialiao [BL34]) twice weekly (administered on Tuesdays and Fridays). Both groups were treated for 4 weeks. The 5-question international index of erectile function (IIEF-5) score, erectile hardness assessment (EHS) score, TCM syndrome score, serum sex hormone levels (follicle-stimulating hormone [FSH], luteinizing hormone [LH], prolactin [PRL], testosterone [T]), penile hemodynamic parameters [peak systolic velocity (PSV) of penile cavernosal artery, end-diastolic velocity (EDV), resistance index (RI)] were compared before and after treatment between the two groups, and the safety and clinical efficacy were evaluated. RESULTS: After treatment, the IIEF-5 scores, EHS scores, serum T levels, PSV and RI of penile cavernosal artery were increased compared with those before treatment in the two groups (P<0.05). Except for RI, the combination group exhibited significantly higher improvements in the above indexes than those in the western medication group (P<0.05). After treatment, the TCM syndrome scores, the serum FSH, LH levels, and EDV in the two groups and the serum PRL level in the combination group were decreased compared with those before treatment (P<0.05), while the above indexes in the combination group were lower than those in the western medication group (P<0.05). The total effective rate of the combination group was 88.5% (46/52), which was superior to 72.5% (37/51) in the western medication group (P<0.05). No significant adverse reactions occurred in either group. CONCLUSION Herbal cake-separated moxibustion at Baliao acupoints combined with western medicine can regulate sex hormone levels, improve penile blood supply, enhance erectile function and hardness, and is superior to western medication alone, with no observed adverse reactions.

Objective:To evaluate the clinical outcomes after implant restoration in the posterior region of severe periodontitis patients and to investigate the factors of natural tooth affecting the implant from the perspective of improving natural periodontal health, which may provide a reference for clinical practice.Methods:Fifty-three patients with severe periodontitis who visited the Department of Periodontology at the Affiliated Stomatological Hospital of China Medical University from June 2014 to June 2023 and completed posterior implant treatment with single crown were included, among which were 16 males and 37 females, aged (52.2±8.0) years old, with a total of 136 implants, 135 adjacent natural teeth in the edentulous area. We retrospectively compared the changes of probing depth (PD), bleeding on probing (BOP) and tooth mobility (TM) before and after implant placement. Besides, we explored the effects of the natural periodontal status on PD, BOP and marginal bone loss (MBL) of the implant at the last follow-up examination by univariate analysis and multivariate analysis.Results:Fifty-three patients were followed up for (44.5±14.1) months in average, with longest interval of (8.3±2.7) months. The PD of adjacent natural teeth in the edentulous area improved from 4.3 (3.6, 4.6) mm before implantation to 3.6 (3.2, 4.0) mm in the last review ( P<0.01), while the proportion of BOP (+) improved from 69.6% (94/135) before implantation to 46.7% (63/135) in the last review ( P<0.01). The proportion of teeth with mobility≥Ⅱ decreased from 15.6% (21/135) to 5.9% (8/135) ( P<0.01). The percentage of natural teeth with PD≥4 mm in the same segment improved from 21.0% (13.3%, 26.0%) before implantation to 18.0% (12.0%, 25.0%) in the last review ( P<0.05). The BOP (+)% improved from 29.0% (24.0%, 35.0%) before implantation to 23.0% (18.0%, 31.0%) in the last review ( P<0.05), and the number of teeth with mobility≥Ⅱ decreased from 0.0 (0.0, 1.0) to 0.0 (0.0, 0.8) ( P<0.05). The functional tooth unit score of full natural teeth increased from 8.0 (6.0, 10.0) points before implantation to 12.0 (12.0, 12.0) points in the last review ( P<0.01). PD≥4 mm % increased from 11.0% (6.0%, 25.0%) before implantation to 13.0% (3.0%, 21.0%) in the last review ( P<0.05) and there was no significant differences in BOP (+)% [(17.0±9.7) % vs (14.6±7.2) %, P>0.05]. The number of teeth with mobility≥Ⅱ decreased from 1.0 (0.0, 1.8) to 0.0 (0.0, 0.8) ( P<0.05). Conclusions:Under the premise of regular supportive care, implant restorative treatment in the posterior region of severe periodontitis patients is helpful to improve the PD, BOP and TM of remaining natural teeth. Besides, the stages and grades of periodontitis at initial diagnosis can affect the PD and BOP of implants.

Objective:To evaluate the hemostatic effects of our self-designed pelvic band with inflatable balloon in a swine model of hemodynamically unstable pelvic fracture.Methods:"Open-book like" fractures were created with the external iliac blood vessels exposed in 24 12-month-old female Bama miniature pigs which were randomly divided into 4 groups ( n=6). Group C (the control group) was subjected to no treatment other than exposure of the external iliac blood vessels, group D to no treatment following destruction of the external iliac blood vessels, group T1 to fixation with simple pelvic band after destruction of the external iliac blood vessels, and group T2 to fixation with our self-designed pelvic band with inflatable balloon after destruction of the external iliac blood vessels. The 4 groups were compared in terms of 40-min survival rate, bladder pressure, peak lactate value, total blood loss, bleeding rate, infusion rate, and angiographic images. Results:There was no significant difference in the baseline indexes among the 4 groups before experiment, showing comparability ( P>0.05). The 40-min survival rate in group T2 was 83.3% (5/6), significantly higher than that in groups D and T1 [0% (0/6) and 0% (0/6)] ( P<0.05). There were no significant differences among groups C, D, T1 and T2 in bladder pressure [(6.67±1.03) mmHg, (5.83±1.94) mmHg, (6.00±1.55) mmHg, and (6.00±1.10) mmHg] or in total blood loss among groups D, T1 and T2[(1,198.0±182.9) mL, (1,252.0±148.4) mL, and (1,150.0±125.7) mL] (all P>0.05). The peak lactate value in group T2 [(2.26±0.24) mmol/L] was significantly lower than that in group D [(5.00±0.60) mmol/L] and group T1 [(3.86±0.57) mmol/L], and the bleeding rate and infusion rate in group T2 [(25.83±5.49) mL/min and (26.00±4.69) mL/min] were also significantly lower than those in group D [(83.50±19.85) mL/min and (71.50±29.11) mL/min] and group T1 [(54.17±15.59) mL/min and (54.17±8.98) mL/min] (all P<0.05). Angiography showed contrast agent extravasation in group T2, especially from the artery, but the extravasation speed in group T2 was significantly slower than that in group D. Conclusion:In a swine model of hemodynamically unstable pelvic fracture, our self-designed pelvic band with inflatable balloon has a definite hemostatic effect on vascular injury which is better than that of a simple pelvic band.

Objective:To investigate whether etomidate affects inflammatory response and apoptosis of PC12 cells induced by hypoxia by regulating miR-142-3p.Methods:PC12 cells were pretreated with different doses(2,6,12 μmol/L)of etomidate to establish hypoxia model;PC12 cells that transfected with miR-142-3p mimics or inhibitors were pretreated with 0 or 12 μmol/L of etomidate to establish hypoxia model.Cell viability,apoptosis and protein(CyclinD1,Cleaved-caspase-3)expressions were detected by CCK-8 method,flow cytometry and Western blot,respectively.ELISA was used to detect levels of inflammatory factors TNF-α,IL-1β,IL-6.Expression of miR-142-3p was detected by RT-qPCR.Results:Etomidate increased hypoxia-induced PC12 cells activity and expres-sion of CyclinD1 protein and miR-142-3p,while decreased cell apoptosis rate,Cleaved-caspase-3 protein expression and levels of inflammatory factors TNF-α,IL-1β,IL-6(P<0.05).Up-regulation of miR-142-3p increased activity and expression of CyclinD1 pro-tein of hypoxia-induced PC12 cells,while decreased cell apoptosis rate,Cleaved-caspase-3 protein expression and levels of inflamma-tory factors TNF-α,IL-1β,IL-6(P<0.05).Down-regulation of miR-142-3p reversed effects of etomidate on hypoxia-induced PC12 cell activity,apoptosis and expressions of inflammatory factors(P<0.05).Conclusion:Etomidate can reduce inflammatory response and apoptosis of PC12 cells induced by hypoxia,and its mechanism may be related to the up-regulation of miR-142-3p expression in cells.

China is a country with high incidence of esophageal cancer. In recent years, with the deepening research, the value of neoadjuvant therapy in locally advanced resectable esophageal cancer has been widely approved by clinicians, compared with surgery alone or adjuvant therapy. However, the survival results of different neoadjuvant therapy options may be quite different, and many problems remain unresolved. In this article, a systemic literature review was carried out to summarize the radiotherapy target, radiotherapy dose, chemotherapy regimen of neoadjuvant chemoradiotherapy and time to surgery, as well as review the research status and progress on targeted therapy and immunotherapy as neoadjuvant therapy for esophageal cancer.

The phenylacetone monooxygenase, isolated from Thermobifida fusca, mainly catalyzes Baeyer-Villiger oxidation reaction towards aromatic compounds. Met446 plays a vital role in catalytic promiscuity, based on the structure and function of phenylacetone monooxygenase. Mutation in Met446 locus can offer enzyme new catalytic feature to activate C-H bond, oxidizing indole to finally generate indigo and indirubin, but the yield was only 1.89 mg/L. In order to further improve the biosynthesis efficiency of the whole-cell catalyst, metabolic engineering was applied to change glucose metabolism pathway of Escherichia coli. Blocking glucose isomerase gene pgi led to pentose phosphate pathway instead of the glycolytic pathway to become the major metabolic pathways of glucose, which provided more cofactor NADPH needed in enzymatic oxidation of indole. Engineering the host E. coli led to synthesis of indigo and indirubin efficiency further increased to 25 mg/L. Combination of protein and metabolic engineering to design efficient whole-cell catalysts not only improves the synthesis of indigo and indirubin, but also provides a novel strategy for whole-cell catalyst development.
