BACKGROUND:With the development of the aging trend of society,the incidence of femoral neck fractures is increasing.Currently,the preferred surgical treatment is cannulated screw internal fixation.However,post-surgical femoral neck shortening occurs in some cases,resulting in impaired hip functionality.OBJECTIVE:To investigate the incidence of femoral neck shortening following the use of half-threaded cannulated screws for internal fixation in patients with femoral neck fractures,to analyze the effect on hip function,and to identify factors contributing to neck shortening.METHODS:A retrospective analysis was conducted on the medical records of 102 patients treated with half-threaded cannulated screws in an inverted triangle setup for femoral neck fractures at Affiliated Hai'an Hospital of Nantong University from January 2016 to January 2021.This group included 36 males and 66 females at the mean age of(57.2±7.7)years,with 34 cases of Garden type Ⅰ and Ⅱ fractures and 68 of Garden type Ⅲ and Ⅳ fractures.The mean bone mineral density value T was-2.8 SD.The Harris score was used to evaluate the hip function.During the follow-up period,the occurrence of femoral neck shortening was determined using X-ray imagery,and the factors influencing this shortening were examined using both univariate and multivariate regression analyses.RESULTS AND CONCLUSION:(1)Among the 102 patients with femoral neck fractures,30 patients developed femoral neck shortening,accounting for 29.4％.72 patients had no femoral neck shortening(70.6％).(2)The Harris score for patients experiencing neck shortening was significantly lower than that for patients without shortening(P＜0.05).(3)The study identified several factors associated with femoral neck shortening following the internal fixation of femoral neck fractures included age,gender,bone mineral density value T,preoperative Garden classification,and quality of reduction.These factors not only affect the shortening of the femoral neck after surgery,but are also directly related to the functional performance of the patient's hip joint.(4)Femoral neck shortening after surgery for femoral neck fracture is associated with various clinical parameters,especially the patient's age,gender,bone mineral density,preoperative classification,and accuracy of reduction during surgery.

Diabetic nephropathy （DN） is one of the most common and severe microvascular complications of diabetes， with a complex pathogenesis involving immune inflammatory responses， oxidative stress， apoptosis， glomerulosclerosis， renal interstitial fibrosis， and other pathological processes. In recent years， numerous animal or cell model experiments have revealed that the transforming growth factor-β （TGF-β）/mothers against decapentaplegic homolog （Smad）， phosphoinositide 3-kinase （PI3K）/ protein kinase B （Akt）/mammalian target of rapamycin （mTOR）， mitogen-activated protein kinase （MAPK）， AMP-activated protein kinase （AMPK）， nuclear factor-κB （NF-κB）， Janus kinase （JAK）/signal transducer and activator of transcription （STAT）， neurogenic locus notch homolog protein （Notch）， nuclear factor E₂-related factor 2 （Nrf2）， secretory glycoprotein （Wnt）/β-catenin， and other classical signaling pathways play important roles in the occurrence and development of DN. Traditional Chinese medicines， as natural drugs， possess characteristics such as multiple components， multiple targets， and few adverse reactions， demonstrating unique advantages in regulating the aforementioned signaling pathways and improving renal pathological changes. This review summarized recent research progress on the intervention of DN through the regulation of the aforementioned signaling pathways by single compounds and formulas of traditional Chinese medicine， focusing on their mechanisms of action in regulating immune inflammatory responses， inhibiting renal fibrosis， oxidative stress， improving metabolic disorders， and other aspects. The aim is to provide theoretical references for a deeper understanding of the modern pharmacological basis and clinical application of traditional Chinese medicine in the treatment of DN.

ObjectiveTo investigate the effect and underlying mechanism of the Wulao Qisun prescription on pathological new bone formation in ankylosing spondylitis （AS）. MethodsSynovial fibroblasts were isolated from the hip joints of AS patients and observed under a microscope to assess cell morphology. The cells were identified using immunofluorescence staining. The isolated AS fibroblasts were divided into blank group， low drug-containing serum group， medium drug-containing serum group， high drug-containing serum group， and positive drug group. After drug intervention， cell proliferation was measured using the cell counting kit-8 （CCK-8） assay to observe fibroblast growth and determine the optimal intervention time. Alkaline phosphatase （ALP） activity was measured using the alkaline phosphatase assay. Protein expression of osteocalcin （OCN）， osteopontin （OPN）， and runt-related transcription factor 2 （Runx2） was detected by Western blot. The mRNA expression levels of Wnt5a， β-catenin， and Dickkopf-1 （DKK-1） were measured by real-time quantitative polymerase chain reaction （Real-time PCR）. ResultsCompared with the blank group， each drug-containing serum group of Wulao Qisun prescription and the positive drug group inhibited the proliferation of AS fibroblasts and reduced ALP expression （P<0.01）. Compared with the blank group， the low drug-containing serum group of Wulao Qisun prescription downregulated β-catenin mRNA expression （P<0.05）. The medium and high drug-containing serum groups and the positive drug group significantly downregulated Wnt5a and β-catenin mRNA expression （P<0.05， P<0.01）， with the positive drug group showing the most pronounced effect （P<0.01）. The high drug-containing serum group and the positive drug group significantly upregulated DKK-1 mRNA expression （P<0.01）. Compared with the blank group， the low drug-containing serum group of Wulao Qisun prescription inhibited the expression of OPN and Runx2 proteins （P<0.05， P<0.01）， while the medium and high drug-containing serum groups and the positive drug group inhibited the expression of OCN， OPN， and Runx2 proteins （P<0.05， P<0.01）. ConclusionThe Wulao Qisun prescription can inhibit the proliferation and osteogenic differentiation of AS fibroblasts， thereby delaying the formation of pathological new bone in AS. The possible mechanism involves the regulation of Wnt/β-catenin-related gene expression， further inhibiting the transcription of downstream target genes.

Physical examination of the newborn revealed abnormal external genitalia, with well-developed scrotum and fully descended testicle in normal size, but without the penis. Postnatal ultrasound showed no obvious signals of uterus and ovaries in pelvis and had normal bilateral testicles and urinary system. The diagnosis was congenital absence of the penis.

Objective To investigate the effect and mechanism of lentivirus-mediated overexpression of suppressors of cytokine sig-naling 3(SOCS3)on the heart of rats with experimental autoimmune myocarditis(EAM).Methods Thirty Lewis rats were randomly di-vided into a control group,EAM group and EAM+SOCS3 group.The EAM rat model was established by subcutaneous injection of cardiac myosin.On day 0 of the experiment,the EAM+SOCS3 group was injected with lentivirus overexpressing SOCS3 via the tail vein,and the EAM group was injected with an equal amount of empty vector lentivirus.On day 21 of the experiment,all rats underwent echocardio-graphy to evaluate cardiac function and were then euthanized.Hematoxylin-eosin(HE)staining was used to observe the pathological changes of myocardial tissue.Enzyme-linked immunosorbent assay(ELISA)was used to detect the levels of serum cardiac troponin T,creatine kinase-myocardial band,B-type natriuretic peptide,and myocardial interleukin-6,interleukin-1 β and tumor necrosis fac-tor-α.Immunohistochemistry,real-time quantitative PCR(RT-qPCR)and Western blot(WB)were used to detect the expressions of SOCS3,Janus kinase 2(JAK2),signal transducer and activator of transcription 3(STAT3),monocyte chemoattractant protein-1(MCP-1),and transforming growth factor-β(TGF-β)in myocardial tissue.Results The myocardial pathological score,serum lev-els of cardiac troponin T,creatine kinase-myocardial band,B-type natriuretic peptide,and myocardial levels of interleukin-6,inter-leukin-1β,and tumor necrosis factor-α in the EAM group were significantly higher than those in the control group(P＜0.05).The cardiac function of the EAM group was significantly lower than that of the control group(P＜0.05).The mRNA and protein expressions of myocardial JAK2,STAT3,MCP-1 and TGF-β in the EAM group were significantly higher than those in the control group(P＜0.05).These indexes in the EAM+SOCS3 group were significantly restored compared with those in the EAM group(P＜0.05).The mRNA and protein expressions of SOCS3 in the myocardial tissue of the EAM+SOCS3 group were significantly higher than those in the EAM group(P＜0.05).Conclusion Overexpression of SOCS3 may ameliorates the inflammatory response of the myocardium in EAM rats and im-prove cardiac function by inhibiting the JAK2/STAT3 signaling pathway and downregulating the expressions of MCP-1 and TGF-β.

Objective To evaluate the effects of the method of blood-cooling and blood stasis-resolving on heart function and prognosis in patients with sepsis-induced myocardial dysfunction(SIMD).Methods Sixty patients with SIMD admitted to the department of critical care medicine of Affiliated Hospital of Nanjing University of Chinese Medicine from June 2022 to October 2024 were enrolled as study subjects.The patients were divided into treatment group and control group according to random number table,with 30 patients in each group.All patients received conventional treatments,the patients in the treatment group were given Taohe Chengqi decoction(Persicae Semen 12 g,Chinese rhubarb 12 g,Cinnamon twig 6 g,Licorice root 6 g and Sodium Sulfate 6 g),the decoction was concentrated to 200 mL and taken in 2 divided doses in the morning and evening,one dose daily;and the patients in the control group were given the same amount of warm water.The total course of treatment lasts for 7 days.The differences in indicators of cardiac function[brain natriuretic peptide(BNP),cardiac troponin I(cTnI),MB isoenzyme of creatine kinase(CK-MB),aspartate aminotransferase(AST)]and echocardiographic parameters[left ventricular ejection fraction(LVEF),left ventricular end-diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD),mitral orifice early/late diastolic blood flow velocity ratio(E/A ratio),E/mitral and tricuspid valve ostia and the peak early diastolic velocity(E/e')]at admission,at 1st and 7th day after treatment,and prognosis indexes[mechanical ventilation time,intensive care unit(ICU)length of stay,total hospital stay,28-day survival rate]were compared between two groups.Draw the Kaplan-Meier survival curve and compare the difference in the 28-day cumulative survival rate between the two groups of patients.Results After 7 days therapy,LVEF of the treatment group was significantly higher than that the control(0.524±0.132 vs.0.458±0.118,P<0.05)and E/e'ratio of the treatment group was significantly lower than the control group[11.17(9.57,12.04)vs.11.82(11.28,13.72),P<0.05].There were no significant differences in the 28-day mortality and total hospital stay time between the two groups,but mechanical ventilation time[days:7.00(0.00,11.00)vs.12.50(3.50,21.75),P<0.05]and stay time of ICU[days:14.50(7.75,25.00)vs.21.00(14.25,31.50),P<0.05]in the treatment group were shorter than those in the control group.The Kaplan-Meier survival showed that the cumulative 28-day survival rate was similar between two groups(Log-Rank:χ2=1.448,P=0.229).Conclusion The method of blood-cooling and blood stasis-resolving could decrease mechanical ventilation time and length of stay in ICU of SIMD patients and could increase LVEF in the treatment group.

Objective:To investigate the effect of repetitive transcranial magnetic stimulation(rTMS)on sleep structure and quality in children with autism spectrum disorder(ASD).Methods:Sixty children with ASD who met the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5)criteria were randomly assigned to rTMS treatment group and pseudo-treatment group.The rTMS group received bilateral low-frequency(0.5 Hz)stimulation,and the pseudo-treatment group received pseudo-stimulation at the same time and place.Sleep quality and autism symptoms were assessed at baseline,midpoint(15 sessions),and endpoint(30 sessions),using the Childhood Sleep Disorders Scale(SDSC)and the Behavior Rating Scale for Children with Autism Spectrum Disorders(ABC)before treatment,15 times and 30 times of intervention,and statistical analysis was performed.Results:There was no significant difference in SDSC factor and total score between the two groups before treatment(P＞0.05).After 15 and 30 treatments,the total scores of SDSC and all factors were lower in the rTMS group than in the pseudo-treatment group(P＜0.05).Repeated measurement ANOVA found that there was an interaction be-tween the groups and the number of interventions,that is,the scores of the two groups had different downward trends,and the decline of the treatment group was more obvious than that of the pseudo-treatment group.There was no significant difference in the interaction between ABC scale scores and intervention times(P＞0.05).Conclu-sion:Repetitive transcranial magnetic stimulation significantly improves the sleep structure and quality in children with autism spectrum disorder.

Objective:To analyze the clinical value of delayed solidification of cement at freezing point combined with establishment of cement channels in the treatment of further leakage of cement in percutaneous kyphoplasty (PKP).Methods:A retrospective analysis was performed for the medical records of 261 patients with osteoporotic vertebral fracture in the thoracolumbar segment who underwent PKP treatment in Beijing Puren Hospital from April 2019 to April 2023. According to the method of dealing with PKP cement leakage, it was divided into freezing point group (using bone cement combined with cement channel reconstruction treatment at freezing point temperature) and temperature gradient group (using temperature gradient method). There were 128 cases in the freezing point group, including 37 males and 91 females, aged 75.57±4.60 years (range, 65-85 years), and fracture locations were 18 cases in T 10, 30 cases in T 11, 44 cases in T 12, 23 cases in L 1 and 13 cases in L 2. There were 133 cases in the temperature gradient group, including 36 males and 97 females, aged 75.66±4.51 years (range, 65-85 years), and fracture locations were 17 cases in T 10, 32 cases in T 11, 51 cases in T 12, 22 cases in L 1, and 11 cases in L 2. The intraoperative blood loss, operation time, intravertebral cement area, cement leakage area, cement leakage area increase, cement bolus time and incidence of injection difficulty, as well as the pain visual analogue scale (VAS), Oswestry disability index (ODI), kyphosis angle, the height of the anterior edge of the injured vertebral body and the difference between it before and after surgery were compared. Results:All patients were followed up for 3 consecutive months. The intraoperative blood loss and initial cement leakage area were 9.48±2.64 ml and 32.56±7.05 mm 2 in the freezing point group and 9.04±2.25 ml and 32.86±7.00 mm 2 in the temperature gradient group, respectively, and the difference was not statistically significant ( P>0.05) ; The operation time, the area of bone cement in the vertebral body, the final leakage area of bone cement, and the increase of bone cement leakage in the freezing point group were 55.08±4.13 min, 1 175.45±117.11 mm 2, 35.84±8.67 mm 2, and 0.00(0.00, 13.32) mm 2, respectively, and the temperature gradient group were 53.02±3.96 min, 823.70±144.79 mm 2, and 73.38±29.16 mm 2 and 44.39(20.13, 56.61) mm 2, the differences were statistically significant ( P<0.05). The height of the anterior edge of the vertebral body was 21.54±2.06 mm and 21.24±2.33 mm immediately after surgery and 3 months after surgery in the freezing point group, which were higher than those in the temperature gradient group 21.10±1.60 mm and 18.92±1.51 mm, respectively, and the difference was statistically significant ( P<0.05). The VAS scores of the freezing point group were 2.29±0.62 and 1.03±0.66 points, ODI were 23.20%±3.97%, 10.43%±4.33%, and the kyphosis angles were 9.09°±2.80° and 9.44°±2.93°, respectively, which were lower than those of the temperature gradient group (4.11±0.79 and 2.79±0.65 points), ODI (35.97%±6.42%, and 23.73%±5.72%), and the kyphosis angles (10.24°±2.33° and 13.22°±2.56°), the differences were statistically significant ( P<0.05). The operating time of bone cement in the freezing point group was 10.89±2.35 min, which was longer than that in the temperature gradient group 5.77±0.52 min, and the difference was statistically significant ( t=24.021, P<0.001). The incidence of cement injection difficulty was 0 in the freezing point group and 27.1% (36/133) in the temperature gradient group. Conclusion:The establishment of bone cement combined with bone cement channel at freezing point temperature can effectively prolong the bolus time of bone cement and reduce the re-leakage of bone cement, which is conducive to increasing the injection volume and distribution area of bone cement in the vertebral body, effectively reducing the amount of bone cement leakage and obtaining better clinical efficacy.
