OBJECTIVE:
To observe the clinical efficacy and safety of acupuncture combined with blade needle therapy for knee osteoarthritis (KOA).
METHODS:
A total of 60 patients with KOA were randomly divided into an observation group and a control group, 30 cases each group. The control group received acupuncture at Neixiyan (EX-LE4),Dubi (ST35), Yinlingquan (SP9), Liangqiu (ST34), Xuehai (SP10), Yanglingquan (GB34) and Zusanli (ST36) on the affected side, once every other day, 3 times a week. The observation group received blade needle therapy on the basis of the treatment in the control group, once every 3 days, 2 times a week. Both groups were treated for 4 weeks. Before treatment, after 2, 4 weeks of treatment, and after 1 month of treatment completion (in follow-up), the scores of pain visual analogue scale (VAS), Western Ontario and McMaster Universities osteoarthritis index (WOMAC) and Lequesne index were observed in the two groups, and the clinical efficacy and safety were evaluated.
RESULTS:
After 2, 4 weeks of treatment and in follow-up, the pain VAS scores, Lequesne index scores, and pain, stiffness, function scores of WOMAC in both groups were decreased compared with those before treatment (P<0.05), and the VAS scores, Lequesne index scores and pain, function scores of WOMAC in the observation group were lower than those in the control group (P<0.05). The effective response rate in the observation group was 76.7% (23/30), while that in the control group was 70.0% (21/30), there was no statistically significant difference in the effective response rates between the two groups (P>0.05). No adverse reactions were observed in either group.
CONCLUSION
Acupuncture combined with blade needle therapy could alleviate pain and promote functional recovery in KOA patients, and achieve long-lasting improvements.

BACKGROUND:Kidney deficiency is the main pathogenesis of osteoporosis.To study the relationship between the two major syndrome types of kidney deficiency,Kidney-Yang deficiency and Kidney-Yin deficiency,is beneficial for the development of clinical diagnosis and treatments based on the combination of disease and syndrome. OBJECTIVE:To evaluate the biomechanical differences of the rat femurs with Kidney-Yang deficiency and Kidney-Yin deficiency caused by Yougui pills,and to demonstrate the scientific efficacy of medication based on the combination of disease and syndrome in osteoporosis from a biomechanical perspective. METHODS:The bilateral ovaries of 60 female Sprague-Dawley rats were surgically removed to establish an ovariectomized osteoporosis model.At 10 weeks after modeling,all the rats were randomly divided into a Kidney-Yang deficiency group(n=30)and a Kidney-Yin deficiency group(n=30).Rats with Kidney-Yang deficiency were given gluteal intramuscular injection of hydrocortisone,while rats with Kidney-Yin deficiency were orally administered with thyroid tablet suspension,once a day,for 14 consecutive days.After successful modeling,20 rats in each group were given a suspension of Yougui pills by gavage once a day for 12 consecutive weeks and the remaining 10 rats were used as the control group without intervention.After gavage,the microstructural parameters of the bone were measured using Micro-CT scanning.Three-point bending,finite element simulation,femoral head compression,and surface indentation distribution experiments of the femurs were performed on a mechanical testing machine. RESULTS AND CONCLUSION:Micro-CT revealed that the femoral bone density,bone volume fraction,bone surface density,trabecular number,and trabecular separation were improved in the Kidney-Yin deficiency+Yougui pills group compared with the Kidney-Yin deficiency group(P<0.05);the femoral bone volume fraction,bone surface density,trabecular number,and trabecular thickness were improved in the Kidney-Yang deficiency+Yougui pills group compared with the Kidney-Yang deficiency group(P<0.05).The three-point bending experiment showed that the femur elastic modulus,maximum bending strength and bending fracture strength were decreased(P<0.05)and toughness was increased(P<0.05)in the Kidney-Yang deficiency+Yougui pills group compared with the Kidney-Yang deficiency group.Finite element simulation showed that Yougui pills could significantly improve the bending resistance of the femurs in the Kidney-Yang deficiency group,but had no significant effect on the Kidney-Yin deficiency group.The femoral head compression experiments showed that Yougui pills could enhance the ability of the femoral head to resist deformation in the Kidney-Yang deficiency group,but there was no significant difference in the effect of Yougui pills on the surface properties of the femoral head in the Kidney-Yin deficiency group and the Kidney-Yang deficiency group.To conclude,Yougui pills can significantly enhance the biomechanical properties of the osteoporotic bones with Kidney-Yang deficiency,but have no significant effect on the osteoporotic bone with Kidney-Yin deficiency.

Objective:To investigate the effect of perineal single-port robot-assisted radical prostatectomy.Methods:A retrospective analysis was conducted on clinical data from 60 patients who underwent perineal single-port robot-assisted laparoscopic radical prostatectomy at our hospital between July 2019 and July 2022. The mean age of the patients was (65.9±7.6) years and the mean BMI was (24.1±2.9) kg/m 2. The median (IQR) prostate volume was 32.7 (23.8, 41.2) ml, and the median (IQR) preoperative PSA value was 8.8 (6.8, 12.6) ng/ml. Preoperative pathology revealed a Gleason score of 6 in 21 patients, Gleason score of 7 in 35 patients and Gleason score of 8 in 4 patients. There were 12 patients clinically staged as T 1 and 48 patients as T 2. A total of 18 patients underwent a total of 23 previous abdominopelvic surgeries. The patient is placed in an exaggerated lithotomy position with the head down and feet elevated approximately 15°. A 3-5 cm incision was made approximately 2 cm above on the mid-perineum between the bilateral ischial tuberosities. Next, the rectourethral muscle was divided, and the space anterior to the rectum was developed by blunt dissection. The levator ani muscles were separated to expose Denonvilliers’ fascia. Then, the disposable multi-channel laparoscopic surgical access system is inserted with a surgical wound protector. Denonvilliers’ fascia was incised transversely and the ampulla of the vas deferens, which were subsequently divided. Blunt separation is performed on both sides along the capsule of the prostate, and then, the vascular pedicles of the prostate are ligated. The membranous urethra was severed after complete urethral separation at the tip of the prostate at the urethral junction. The bladder neck was freed and dissected. The prostate and seminal vesicles were removed and a vesicourethral anastomosis is performed. A perineal drain were left in place. Preoperative and postoperative variables, complications, early urinary continence rate(Return of urinary continence status was defined as using no more than one safety pad per day) and oncological outcomes of patients were recorded. Results:All 60 surgeries were successfully completed without conversions or additional incisions. The median (IQR) total operative time was 200.0(153.8, 236.3) min, the median (IQR) console operating time was 107.5(90.0, 150.0) min and the median (IQR) estimated blood loss was 50.0(50.0, 100.0) ml. Positive surgical margins were detected in five patients (8.3%). The continence rate was 43.1%(22/51), 64.7%(33/51), 92.0%(46/50) and 98.0%(49/50), and the PSA undetectable rate was 94.6%(48/51), 98.2%(49/51), 96.6%(47/50) and 100%(50/50) at the 1, 3, 6, and 12 months after surgery. Only 1(1.7%) patient experienced biochemical recurrence 9 months after surgery. The overall complication rate was 20%, including two cases of acute respiratory distress syndrome, one case of rectal injury, one case of urinary tract injury, two cases of poor wound healing, three cases of incision infection, two cases of urinary tract infection and one case of bladder neck-urethral orifice anastomotic stricture.Conclusions:Perineal single-port robot-assisted radical prostatectomy might be safe and feasible surgical treatments for localized prostate cancer, especially for patients with a history of complex abdominal or pelvic surgery. It also showed advantages in early continence. The anatomical structure of the perineal region should be considered, and the correct incision position should be chosen. Specific incision protection measures should also be used for the incision in this particular area of the perineal region to reduce the risk of perioperative complications.

Objective:To evaluate the value of curative effect in neuromyelitis spectrum disease (NMOSD) based on circulatory function evaluation of intracerebral glymphatic system by using diffusion tensor imaging analysis along the perivascular space.Methods:The clinical and imaging data of 23 patients diagnosed with NMOSD at Tianjin Medical University General Hospital from March 2018 to December 2019 were retrospectively analyzed in this study. The clinical data included expanded disability status scale (EDSS), average relapse rate (ARR) and retinal nerve fiber layer (RNFL) thickness at baseline and 1 year follow-up after treatment. Among the 23 NMOSD patients, there were 22 females and 1 male, aged from 21 to 71 (45±13) years old. All the patients underwent MR scans at both baseline and 1 year after treatment, and the scanning sequences included cerebral 3D-T 1WI, T 2WI, diffusion tensor imaging and cervical spinal sagittal 3D-T 2WI, and the cervical spinal cord volume and bilateral diffusion tensor imaging analysis along the perivascular space index (ALPS index) were calculated. The partial correlation test was used to analyze the correlations between ALPS index and the clinical indicators such as EDSS, ARR, and bilateral RNFL, with the control variables as gender, age, years of education and course of disease. The multiple linear regression model was used to analyze the independent predictors for ALPS index and EDSS after treatment. Receiver operating characteristic curve (ROC) and area under the curve (AUC) were used to evaluate the diagnostic value of NMOSD treatment outcome by using ALPS index. Results:When controlling for gender, age, years of education and course of disease, there were significant negative correlations between right ALPS index and EDSS ( r=-0.50, P=0.048), bilateral average ALPS index and EDSS ( r=-0.53, P=0.034), left ALPS index and ARR ( r=-0.58, P=0.018), while there was significant positive correlations between right ALPS index and RNFL ( r=0.88, P=0.008) at 1 year follow-up after treatment. Multiple linear regression analysis showed that cervical spinal cord volume was an independent impact factor of bilateral average ALPS indexes (β=0.24, 95%CI 0.10-0.38, P=0.002), and bilateral average ALPS indexes (β=-3.22, 95%CI -5.97--0.48, P=0.024) and right RNFL (β=-0.05, 95%CI -0.08--0.02, P=0.002) at baseline were the independent impact factors of EDSS after treatment. ROC curve analysis showed that the bilateral average ALPS index at baseline had the best efficacy in predicting the curative effect of NMOSD patients with AUC=0.92. Conclusions:After treatment, NMOSD patients with severe clinical disability, high frequency of disease attack, poor visual performance, and severe cervical spinal cord atrophy have more serious impairment of intracerebral glymphatic system circulatory function. The ALPS index could help in predicting the clinical curative effect of NMOSD patients.

Traumatic cerebrospinal fluid leakage commonly presents in traumatic brain injury patients, and it may lead to complications such as meningitis, ventriculitis, brain abscess, subdural hematoma or tension pneumocephalus. When misdiagnosed or inappropriately treated, traumatic cerebrospinal fluid leakage may result in severe complications and may be life-threatening. Some traumatic cerebrospinal fluid leakage has concealed manifestations and is prone to misdiagnosis. Due to different sites and mechanisms of trauma and degree of cerebrospinal fluid leak, treatments for traumatic cerebrospinal fluid leakage varies greatly. Hence, the Craniocerebral Trauma Professional Group of Neurosurgery Branch of Chinese Medical Association and the Neurological Injury Professional Group of Trauma Branch of Chinese Medical Association organized relevant experts to formulate the " Chinese expert consensus on the diagnosis and treatment of traumatic cerebrospinal fluid leakage in adults ( version 2023)" based on existing clinical evidence and experience. The consensus consisted of 16 recommendations, covering the leakage diagnosis, localization, treatments, and intracranial infection prevention, so as to standardize the diagnosis and treatment of traumatic cerebrospinal fluid leakage and improve the overall prognosis of the patients.

Objective:To compare the efficacy and safety of Tonghua Dongbao′s insulin aspart injection (Rishulin) and NovoRapid (Novo Nordisk) in the treatment of diabetes.Methods:A 26-week, randomized, open-label, parallel-group, positive control drug and non-inferiority trial was conducted in 23 centers in China. A total of 563 diabetes with poor blood glucose control treated with insulin for at least 3 months before were included. The subjects were randomized(stratified block random method) into those receiving Rishulin or NovoRapid at a ratio of 3∶1. Both groups were combined with basal insulin (Lantus). The primary endpoint was the change in glycosylated hemoglobin (HbA1c) from baseline to the end of 24 weeks of treatment.Results:For full analysis set, after 24 weeks of treatment, HbA1c level of Ruishulin group decreased from (8.66±1.28)% to (7.77±1.09)% ( P<0.001), and that of NovoRapid group decreased from (8.47±1.28) % to (7.65±0.97) % ( P<0.001). Treatment difference in HbA1c (NovoRapid group-Ruishulin group) was -0.061% (95% CI -0.320-0.199). HbA1c<7.0% target reacing rates were 24.26% and 21.21% ( P=0.456), and HbA1c<6.5% target reacing rates were 9.65% and 6.82% ( P=0.310) in Ruishulin group and NovoRapid group, repectively. The standard 2 hours postprandial blood glucose (2hPG) in Ruishulin group decreased from (16.23±5.22) mmol/L to (12.65±4.57) mmol/L ( P<0.001), and 2hPG in NovoRapid group decreased from (16.13±5.37) mmol/L to (11.91)±4.21) mmol/L ( P<0.001). The fingertips blood glucose at 7-point of both groups exhibited varying degrees of reduction compared with those at baseline, repectively. Positive ratios of specific antibodies were 31.68% in Ruishulin group and 36.36% in NovoRapid group ( P=0.320). Ratios of negative to positive were 7.43% and 10.61% ( P=0.360), and ratios of positive to negative were 10.40% and 7.58% ( P=0.360) in Ruishulin group and NovoRapid group, respectively. The incidence of hypoglycemia was 60.05% and 55.40% ( P=0.371), and the incidence of adverse events was 76.60% and 77.70% ( P=0.818) in Ruishulin group and NovoRapid group, respectively. Conclusions:Rishulin is not inferior to NovoRapid, and has shown good efficacy and safety. It can be an ideal choice for clinicians in patients with poor blood glucose control with insulin.

Inflammation plays an important role in the development of acute lung injury (ALI). Severe pulmonary inflammation can cause acute respiratory distress syndrome (ARDS) or even death. Expression of proinflammatory interleukin-1β(IL-1β) and inducible nitric oxide synthase (iNOS) in the process of pulmonary inflammation will further exacerbate the severity of ALI. The purpose of this study was to explore the effect of Palrnatine (Pa) on lipopolysaccharide (LPS)-induced mouse ALI and its underlying mechanism. Pa, a natural product, has a wide range of pharmacological activities with the potential to protect against lung injury. Western blotting and quantitative real-time polymerase chain reaction (qRT-PCR) assays were performed to detect the expression and translation of inflammatory genes and proteins in vitro and in vivo. Immunoprecipitation was used to detect the degree of P65 translocation into the nucleus. We also used molecular modeling to further clarify the mechanism of action. The results showed that Pa pretreatment could significantly inhibit the expression and secretion of the inflammatory cytokine IL-1β, and significantly reduce the protein level of the proinflammatory protease iNOS, in both in vivo and in vitro models induced by LPS. Further mechanism studies showed that Pa could significantly inhibit the activation of the protein kinase B (Akt)/nuclear factor-κB (NF-κB) signaling pathway in the LPS-induced ALI mode and in LPS-induced RAW264.7 cells. Through molecular dynamics simulation, we observed that Pa was bound to the catalytic pocket of Akt and effectively inhibited the biological activity of Akt. These results indicated that Pa significantly relieves LPS-induced ALI by activating the Akt/NF-κB signaling pathway.
