ABSTRACT
The role of 3-phosphoinositide-dependent kinase 1 (PDK1) has been welldocumented in the development of diabetes. This review offers a thorough examination of its composition and associated routes, specifically focusing on insulin signaling and glucose processing. By examining the precise connection between PDK1 and diabetes, various strategies specifically targeting PDK1 were also investigated. Additionally, recent discoveries from mouse models were compiled where PDK1 was knocked out in certain tissues, which demonstrated encouraging outcomes for focused treatments despite the absence of any currently approved clinical PDK1 activators. Moreover, the dual nature of PDK1 activation was discussed, encompassing both anti-diabetic and pro-oncogenic effects. Hence, the development of a PDK1 modifier is of utmost importance, as it can activate anti-diabetic pathways while inhibiting pro-oncogenic pathways, thus aiding in the treatment of diabetes. In general, PDK1 presents a noteworthy opportunity for future therapeutic strategies in the treatment of diabetes.
ABSTRACT
Objective To evaluate the clinical efficacy of Chevron minimally-invasive osteotomy and internal fixation with ISO intramedullary plate plus traditional Chinese medicine(TCM)bone-setting manipulations for the treatment of moderate hallux valgus.Methods A retrospective study was conducted.A total of 49 patients(62 feet)with moderate hallux valgus were treated with Chevron minimally-invasive osteotomy and internal fixation with ISO intramedullary plate,and were given TCM bone-setting manipulations before the operation,during the operation,and after the operation.The efficacy was evaluated by using the Visual Analogue Scale(VAS)score and the American Orthopedic Foot and Ankle Society(AOFAS)forefoot score after the operation.Before the operation and 12 months after the operation,the hallux valgus angle(HVA),intermetatarsal angle(IMA)between the first and second metatarsal bone,and the distal metatarsal articular angle(DMAA)showed by X-ray imaging in the weight-bearing position of the foot were recorded.Results(1)All of the 49 patients were followed up for 12 to 24 months,with a mean of(20.6±3.1)months.(2)The X-ray imaging assessment showed that 12 months after the operation,the mean HVA,IMA and DMAA values of the 49 patients(62 feet)were significantly lower than those before the operation,and the differences were all statistically significant(P<0.01).(3)Twelve months after the operation,the pain VAS score of 49 patients was(3.14±1.21)points,which was significantly lower than the preoperative score points(7.26±2.52),and the difference was statistically significant(P<0.01).(4)The assessment of joint function showed that 12 months after the operation,the scores of various AOFAS items of pain,function and hallux alignment as well as the overall AOFAS scores of 49 patients were significantly higher than those before the operation,and the differences were statistically significant(P<0.01).(5)For the 62 feet in 49 patients,the excellent efficacy was achieved in 53 feet,good efficacy was achieved in 7 feet,and fair efficacy was achieved in 2 feet,with the fine rate of 96.77%(60/62).Conclusion For the treatment of moderate hallux valgus,the application of Chevron minimally-invasive osteotomy and internal fixation with ISO intramedullary plate plus TCM bone-setting manipulations is effective on promoting the reset of hallux-metatarsophalangeal joint,restoring the balance of the joint,and maintaining the equilibrium state of the joint through postoperative rehabilitation guidance.The combined therapy exerts certain efficacy,reduces the recurrence rate,and eventually achieves the early rehabilitation after the operation.
ABSTRACT
Objective:To explore the application value of posture adaptation training combined with continuous pas-sive exercise rehabilitation for patients after coronary artery bypass grafting(CABG).Methods:A total of 100 pa-tients with coronary heart disease(CHD)undergoing CABG in our hospital were enrolled,divided into single group(n=50,received single continuous passive exercise rehabilitation intervention)and combined group(n=50,re-ceived posture adaptation training based on single group)according to color grouping method.Both groups were in-tervened for two months.Clinical indexes,cardiac function indexes,cognitive function,exercise endurance,serum levels of neuron specific enolase(NSE),S-100β protein and satisfaction were analyzed and compared between two groups.Results:Compared with single group after intervention,there were significant reductions in first out of bed time,first anal exhaust time and length of hospital stay,and significant rise in left ventricular ejection fraction(LVEF),cardiac index(CI),left ventricular fractional shortening(LVFS),score of Montreal cognitive assessment(MoCA)scale,6min walking distance,and significant reductions in serum levels of NSE[(19.93±1.90)μg/L vs.(16.59±2.25)μg/L]and S-100β protein[(6.72±0.34)μg/L vs.(3.96±0.19)μg/L]in combined group,P=0.001 all.Satisfaction in combined group was significantly higher than that of single group(94.00%vs.80.00%,P=0.037).Conclusion:Posture adaptation training combined with continuous passive exercise rehabilitation can sig-nificantly improve the clinical indexes,promote cardiopulmonary function and cognitive function recovery in pa-tients undergoing coronary artery bypass grafting after operation.
ABSTRACT
Objective:To explore the relationship between the polymorphisms of AHNAK2 gene rs12882641,rs28583515 and rs2582497 loci and coronary heart disease(CHD)in the population of Xinjiang.Materials:This study used a case-control method,a total of 602 patients who were hospitalized and underwent coronary angiogra-phy(CAG)at ourheart center from Jan 2019 to Dec 2021 were selected.According toCAG results,the patients were divided into CHD group(n=301)and non-CHD group(n=301).The AHNAK2 gene rs12882641,rs28583515 and rs2582497 loci were genotyped using the improved multiple ligase detection reaction(iMLDR)technique,and the relationship between AHNAK2 gene polymorphisms and CHD was analyzed.Results:Compared with non-CHD group,there was significant rise in the distribution frequencies of AC+CC genotypes(52.8%vs.61.1%,P= 0.040)at rs2582497 locus of the AHNAK2 gene under the dominant model;there was significant reduction in distri-bution frequency of the CC genotype(65.8%vs.53.8%)at the rs28583515 locus of the AHNAK2 gene,and signif-icant rise in distribution frequencies of CT+TT(34.2%vs.46.2%)under the dominant model,TT under the re-cessive model(0.7%vs.3.0%)and CT under the additive model(33.6%vs.43.2%)in CHD group,P<0.05 or<0.01.After adjusting for confounding factors,logistic regression analysis indicated that the dominant model of the rs28583515 locus remained an independent risk factor for CHD(OR=1.509,P=0.036).Conclusion:The AH-NAK2 gene rs28583515 locus is closely related to the occurrence and development of CHD in the Xinjiang popula-tion.The dominant model of the AHNAK2 gene rs28583515 locus is an independent risk factor for CHD.

ABSTRACT
The objective of present study was to develop a simple and reliable voiding spot assay (VSA) system to evaluate the lower urinary tract function of mice, and to establish it as a standardized protocol. Ultraviolet (UV) light was used to screen out the filter paper without autofluorescence and with optimal urine diffusion properties. Next, the appropriate wavelength of UV was determined based on the quality of the photographic image of urine spots on the filter paper. To confirm that the urine stain area on the filter paper was correlated with the amount of urine, a volume-area standard curve was constructed. The utility of this VSA system was validated using female wild-type C57BL/6J mice aged 12-13 weeks, and the data generated under identical procedural settings were compared among laboratories. Furthermore, this VSA system was employed to analyze the changes in voiding patterns in mice with urinary tract infections or transportation stress. No. 4 filter paper with a thickness of 0.7 mm was identified as the most suitable material for VSA, exhibiting no autofluorescence and facilitating optimal urine diffusion. The filter paper retained its integrity during the assay, and there was a linear correlation between urine volume and stained area under 365 nm UV light. Utilizing this VSA system, we determined that female wild-type C57BL/6J mice produced approximately 695.8 μL total urine and 5.5 primary voiding spots (PVS) with an average size of 126.4 μL/spot within 4-h period. Over 84% of PVS volumes ranged from 20 to 200 μL. Notably, PVS volumes of mice were similar across different laboratories. Mice with urinary tract infections or transportation stress exhibited significant changes in VSA parameters, including increased voiding frequency, PVS number, and decreased PVS volume. Therefore, this VSA system can be used to evaluate the urinary function of normal mice, as well as those with urinary tract infection or transportation stress.

Objective:To introduce a novel method of endoscopic forehead lift and its follow-up results.Methods:In the past 7 years, 119 patients underwent endoscopic forehead lift. The parallel incisions were made on the frontalis muscle to relieve the wrinkles of the forehead. Glabella muscles were partially bluntly bitten by minimally invasive forceps. No fixator or suture was applied during the operation. Postoperative FACE-Q scales were issued to patients, and the changes of eyebrow position before and after operation were measured.Results:One week postoperatively, glabella frown and forehead wrinkles were relieved or eliminated as the swell gone. The eyebrow measurement outcome showed that the eyebrows of the patients were definitely raised after the operation. The results of FACE-Q scales showed that patients were highly satisfied with the improvement of frontal wrinkles and glabella frown wrinkles, and with the surgical outcomes and decisions. The patients thought they were averagely 7 years younger after operation. The most common complication was temporary frontal skin numbness, followed by hairline regression.Conclusions:The endoscopic forehead lift can effectively improve the forehead wrinkles and the glabella frown wrinkles which meets the demands of Chinese patients.

After each lecture in module 1 and module 2, the empathy ability of medical students was improved (both P<0.05), which was 34% higher than that before teaching [(132.7±12.5) vs. (99.0±17.4)]. After each lecture in module 2 and module 3, the emotional intelligence of medical students was improved by 34% [(138.5±13.0) vs. (103.0±16.6)] (both P<0.05). Conclusion:The situational doctor-patient communication skills training course based on chest pain center, as a practical course of doctor-patient communication for medical students at the undergraduate stage, can effectively improve students' doctor-patient communication ability, empathy ability and emotional intelligence.
ABSTRACT
Objective:Dorsocervical fat pad is common in middle-aged women. Current treatments include surgical excision and liposuction. We evaluated the therapeutic effect of tumescent liposuction on dorsocervical fat pad. Anatomical study was also carried out to explore the anatomical structure and significance of dorsocervical fat pad.Methods:From Jan. 2009 to Dec. 2018, twenty-seven patients with dorsocervical fat pad were treated with tumescent liposuction in Peking University Third Hospital. Small incisions were made in bilateral scapular region and 4 mm suction cannula was applied. A female cadaver fixed with formaldehyde was dissected to investigate the structure of posterior cervical and dorsal region. The specimens were stained with HE and Masson staining.Results:14 patients were followed up for no less than 6 months, with an average follow-up time of 27 months. Patients' dorsocervical area were flat and smooth after the surgery. Patient satisfaction rate was 100% and no severe complication was reported except bruise and pain. The symptoms of dorsocervical pain in two patients were significantly improved after operation. Anatomical study showed that the dorsocervical fat pad was composed of superficial and deep layer of adipose tissue, with clear boundary between the two layers and no obvious capsule. The collagen fibers in deep layer were more and denser than those in superficial layer.Conclusions:Tumescent liposuction can effectively treat dorsocervical fat pad. The surgery outcome is ideal with little complication.Through the study of the anatomical structure of the dorsocervical fat pad, the operation method and principle of liposuction can be improved and the operation efficiency can be enhanced.

ABSTRACT
Objective@#To investigate the application value of superb microvascular imaging (SMI) in the diagnosis of penile vascular ED.@*METHODS@#Seventy-two ED patients underwent SMI and color Doppler flow imaging (CDFI), all ultrasonographically diagnosed with penile vascular ED. We compared SMI and CDFI in detecting the grades of blood flow in the cavernous artery and the lengths of time needed to obtain satisfactory blood flow spectrum from the patients.@*RESULTS@#SMI mainly revealed grades Ⅲ and Ⅳ blood flow, in 43 and 20 of the 72 patients (87.5%), while CDFI chiefly manifested grades Ⅰ and Ⅱ blood flow, in 26 and 32 cases respectively (80.6%). The former showed significantly better manifestations of the penile cavernous artery than the latter. It took less time to obtain the spectrums of grades Ⅲ and Ⅳ blood flow ([1.52 ± 0.18] and [1.21 ± 0.11] min) than grades Ⅰ and Ⅱ ([5.23 ± 0.44] and [4.46 ± 0.65] min), and SIM took significantly less time than CDFI ([1.32 ± 0.42] vs [4.53 ± 0.67] min, P < 0.05).@*CONCLUSIONS@#SMI is superior to CDFI in better manifesting the blood flow of the penile cavernous artery and shortening the examination time, and therefore deserves a wide application in the diagnosis of vascular ED.
ABSTRACT
AIM:To assess the changes in higher order aberrations after wavefront guided femtosecond laser assisted laser in situ keratomileusis ( FS-LASIK ) for moderate to high astigmatism.?METHODS: Eighty-eight eyes of 50 myopia patients with moderate to high astigmatism were included in this prospective study. There were 51 eyes with moderate astigmatism (≥-1. 50D and <-3. 00D) and 37 eyes with high astigmatism (≥-3. 00D). All patients underwent wavefront guided FS-LASIK. Uncorrected distance visual acuity ( UDVA ) , corrected distance visual acuity (CDVA), keratometry, central corneal thickness ( CCT)and higher order aberrations ( HOAs ) were evaluated before operation and 3mo postoperatively.?RESULTS:At the 3mo after operation, the mean UDVA of all eyes was above 20/20, better than before operation (P<0. 05), but CDVA remained unchanged (P=0. 36) and no eyes lost ≥2 lines of CDVA. Mean astigmstism of 85 eyes ( 97%) was reduced below - 1. 00D, mean astigmatism of 70 eyes ( 80%) was reduced below-0.50D(P<0. 05). The average corneal curvature was flatter by 3. 81 ± 1. 97D and CCT was reduced by 78. 66 ± 37. 22μm, postoperatively (P<0. 05). Coma and trefoil aberrations remained unchanged(P=0. 078, 0. 065). The spherical aberration, secondary astigmatism and the HOA root mean square ( RMS ) increased from 0. 19 ± 0. 06, 0.05±0. 02 and 0. 42±0. 12, preoperatively to 0. 32± 0. 17, 0. 26 ± 0. 08 and 0. 78 ± 0. 28 ( P < 0. 05 ), postoperatively.?CONCLUSION: Wavefront-guided FS-LASIK is a safe and effective option for the patients with moderate to high astigmstism although parts of HOAs increased.

The total area of the perpendicular plate of ethmoid was (1 057.85±184.38) mm2, the lower section area was (474.09±109.60) mm2, and the ratio of middle and lower third to the total area was 0.45±0.07.@*Conclusions@#The thickness of the lower 1/3 segment of the vertical plate of the ethmoid bone is thinner than that of the upper segment, and it is far away from the skull base, which is easily to harvest and meet the application in surgery.
