OBJECTIVE: To investigate the accuracy and safety of pedicle screw placement using 3D-printed auxiliary guides in scoliosis correction surgery for adolescents. METHODS: A retrospective analysis was conducted on the clinical data of 51 patients who underwent posterior scoliosis correction surgery from January 2020 to March 2023. Among them, there were 35 cases of adolescent idiopathic scoliosis and 16 cases of congenital scoliosis. The patients were divided into two groups based on the auxiliary tool used:the 3D-printed auxiliary guide screw placement group (3D printing group) and the free-hand screw placement group (free-hand group, without auxiliary tools). The 3D printing group included 32 patients (12 males and 20 females) with an average age of (12.59±2.60) years;the free-hand group included 19 patients (7 males and 12 females) with an average age of (14.58±3.53) years. The two groups were compared in terms of screw placement accuracy and safety, spinal correction rate, intraoperative blood loss, number of intraoperative fluoroscopies, operation time, hospital stay, and preoperative and last follow-up scores of the Scoliosis Research Society-22 (SRS-22) questionnaire. RESULTS: A total of 707 pedicle screws were placed in the two groups, with 441 screws in the 3D printing group and 266 screws in the free-hand group. All patients in both groups successfully completed the surgery. There was a statistically significant difference in operation time between the two groups (P<0.05). The screw placement accuracy rate of the 3D printing group was 95.46% (421/441), among which the Grade A placement rate was 89.34% (394/441);the screw placement accuracy rate of the free-hand group was 86.47% (230/266), with a Grade A placement rate of 73.31% (195/266). There were statistically significant differences in the accuracy of Grade A, B, and C screw placements between the two groups (P<0.05), while no statistically significant differences were observed in intraoperative blood loss, number of fluoroscopies, correction rate, or hospital stay (P>0.05). In the SRS-22 questionnaire scores, the scores of functional status and activity ability, self-image, mental status, and pain of patients in each group at the last follow-up were significantly improved compared with those before surgery (P<0.05), but there were no statistically significant differences in all scores between the two groups (P>0.05). CONCLUSION In scoliosis correction surgery, compared with traditional free-hand screw placement, the use of 3D-printed auxiliary guides for screw placement significantly improves the accuracy and safety of screw placement and shortens the operation time.

OBJECTIVE To explore the efficacy of Sour Jujube Seed Decoction combined with Huanglian Wendan Decoction on adult chronic insomnia and its effect on hypnotic withdrawal.METHODS 187 patients with chronic insomnia were included for anal-ysis,including 102 in the traditional Chinese medicine(TCM)group and 85 in the western medicine group.The TCM group was trea-ted with Sour Jujube Seed Decoction combined with Huanglian Wendan Decoction,while the western medicine group was treated with benzodiazepine under the consideration of doctor.The intervention period was 1 month,with assessments using the Pittsburgh Sleep Quality Index(PSQI)conducted before and after the intervention.Follow-up evaluations were performed at 3 months and 6 months re-spectively after the intervention.RESULTS There was no significant difference between the two groups at baseline.After the inter-vention,the PSQI scores of patients in both groups were significantly improved(P<0.01).Among them,the TCM group was better than the western medicine group in the improvement of sleep quality and sleeping pills,total PSQI score reduction(P<0.01).The re-sults of linear regression analysis showed that after controlling for confounding factors,the regression coefficients of the TCM group in two different models were1.821 and 1.922 respectively,and the former was statistically significant(P<0.05).By screening patients who took hypnotics at baseline in the TCM group and comparing them with those in the western medicine group,the influencing factors of hypnotic withdrawal were analyzed.During the 3-month follow-up,25 out of 39 patients in the TCM group and 17 out of 80 patients in the western medicine group had hypnotic withdrawal(χ2= 19.25,P<0.001);during the 6-month follow-up,23 of the 39 patients in the TCM group and 18 of the 79 patients in the western medicine group had hypnotic withdrawal(χ2= 13.53,P<0.001),the with-drawal rate of patients in the TCM group was significantly higher than that in the western medicine group.Further regression analysis showed that after adjusting for confounding factors,the results showed that the western medicine group had a significantly higher rate of not withdrawal than the TCM group at 3 months(OR=5.50,95%CI:2.30～13.72)and 6 months(OR=6.43,95%CI:2.54～17.77),and the results were statistically different(P<0.05).CONCLUSION Sour Jujube Seed Decoction combined with Huangli-an Wendan Decoction is effective in treating adult chronic insomnia and assisting in hypnotic withdrawal.

Lung cancer is the leading cause of cancer death and the most common malignant tumor, the long-term survival of which has stagnated in the past several decades. Pileostegia tomentella Hand. Mazz is a traditional Chinese medicine called "Zhongliuteng" (ZLT) in the pharmacopeia, which has been proved to possess a potent anti-tumor effect on various cancers. In this study, the effects of ZLT N-butanol extraction (ZLTN) and ZLT ethyl acetate extraction (ZLTE) on the viability of non-small cell lung cancer cell (NSCLC) lines H1299 and A549 were evaluated. Here, we firstly reported that ZLTE significantly inhibited H1299 cells growth without affecting the release of lactate dehydrogenase (LDH). In addition, ZLTE induced caspase-dependent apoptosis in a concentration-dependent manner and increased the expression cleaved-PARP and decreased pro-caspase-3, pro-caspase-7, pro-caspase-8, and pro-caspase-9. Moreover, ZLTE increased the level of cellular reactive oxygen species (ROS) in H1299 cells to lead to apoptosis, which was reversed by N-acetyl-cysteine (NAC). Taken together, our results revealed that ZLTE induced caspase-dependent apoptosis via ROS generation, suggesting that ZLTE is a promising herbal medicine for the treatment of NSCLC.

Background:Transcranial alternating current stimulation (tACS) offers a new approach for adult patients with major depressive disorder (MDD).The study is to evaluate the efficacy and safety of tACS treating MDD.Methods:This is an 8-week,double-blind,randomized,placebo-controlled study.Ninety-two drug-naive patients with MDD aged 18 to 65 years will receive 20 daily 40-min,77.5-Hz,15-mA sessions of active or sham tACS targeting the forehead and both mastoid areas on weekdays for 4 consecutive weeks (week 4),following a 4-week observation period (week 8).The primary outcome is the remission rate defined as the 17-item Hamilton depression rating scale (HDRS-17) score ≤7 at week 8.Secondary outcomes are the rates of response at weeks 4 and 8 and rate of remission at week 4 based on HDRS-17,the proportion of participants having improvement in the clinical global impression-improvement,the change in HDRS-17 score (range,0-52,with higher scores indicating more depression) over the study,and variations of brain imaging and neurocognition from baseline to week 4.Safety will be assessed by vital signs at weeks 4 and 8,and adverse events will be collected during the entire study.Discussion:The tACS applied in this trial may have treatment effects on MDD with minimal side effects.

Objective: To evaluate the role of the serum testosterone level as an independent predictor of bone metastasis of prostate cancer. METHODS: This study included 165 male patients with prostate cancer confirmed by biopsy. The patients were aged 58－78 (66.6±5.3) years and none had received androgen-deprivation therapy, chemotherapy or radiotherapy previously. We obtained the baseline clinical data from the patients, including prostate biopsy Gleason scores and the levels of serum prostate-specific antigen (PSA), total testosterone (TT), luteinizing hormone (LH), follicle-stimulating hormone (FSH), estradiol (E2), alkaline phosphatase (ALP) and prolactin. According to the results of bone scanning, we divided the patients into a bone metastasis and a non-bone metastasis group and screened out the differential factors by univariate analysis and the independent predictor of bone metastasis using the multivariate non-conditional logistic regression model. RESULTS: Univariate analysis showed no statistically significant differences between the bone metastasis and non-bone metastasis groups in age (P = 0.126) or the levels of serum LH (P = 0.930), FSH (P = 0.763) and E2 (P = 0.256), but that the former had remarkably higher Gleason scores (P < 0.01), total PSA (P <0.01) and ALP (P <0.01) but a lower TT level than the latter (P = 0.013). According to the results of multivariate logistic regression analysis, serum ALP (P <0.01, OR = 1.018 ［1.011－1.026］) and total PSA (P <0.01, OR = 1.029 ［1.015－1.044］) could be regarded as independent predictors of bone metastasis of prostate cancer but not low serum TT (P = 0.531, OR = 0.999 ［0.996－1.002］) or biopsy Gleason score (P = 0.898, OR = 0.787 ［0.412－1.9559］). CONCLUSIONS The low level of serum testosterone is closely associated with but not an independent predictor of bone metastasis of prostate cancer.

OBJECTIVETo evaluate and compare the clinical efficacy and safety of the highly selective alpha receptor antagonist tamsulosin and its combination with the M receptor antagonist tolterodine in the treatment of refractory lower urinary tract symptoms (LUTS) in patients with benign prostatic hyperplasia (BPH).

METHODSWe included in this study 184 BPH patients with refractory LUTS with the disease course of 4 weeks to 2 years, whose LUTS were not alleviated after a week's treatment with tamsulosin. The patients were randomly divided into Groups A and B, the former (n=89) treated with tamsulosin at 0.2 mg qd and the latter (n=95) given tolterodine at 2 mg bid in addition to tamsulosin medication, both for 4 weeks. Scores on IPSS, QOL and Qmax were obtained before and after the treatment, and the improvement of LUTS evaluated after the medication.

RESULTSThe tamsulosin group showed no significant differences before and after the treatment in the scores on IPSS (13.23 +/- 4.39 vs. 12.21 +/- 4.07), QOL (4.23 +/- 1.27 vs 3.53 +/- 0.95) and Qmax ([12.3 +/- 8.39] ml/s vs. [14.1 +/- 8.62] mls) (P > 0.05), while the combination group exhibited significantly higher scores on IPSS and QOL and lower score on Qmax after the medication than before it (IPSS: 14.45 +/- 5.31 vs. 6.56 +/- 2.03, P < 0.05; QOL: 4.45 +/- 0.79 vs. 2.34 +/- 0.73, P < 0.05; Qmax: [11.4 +/- 9.21] ml/s vs. [15.5 +/- 8.35] ml/s, P < 0.01). No severe complications were found in any of the cases.

CONCLUSIONCombination of tamsulosin and tolterodine can significantly alleviate refractory LUTS and improve QOL without causing serious adverse events in BPH patients.

OBJECTIVETo compare the efficacy and safety of sildenafil plus sertraline with those of sertraline alone in the treatment of premature ejaculation (PE).

METHODSSeventy-two patients with PE but without any obvious organic cause were enrolled in this study. They were randomly divided into Groups A and B of equal number. Group A received 50 mg sertraline daily 4 to 6 hours before planned sexual activity for 12 weeks, and Group B were given 50 mg sertraline daily plus 50 mg sildenafil as needed, 1 hour before planned sexual activity, for 12 weeks. Before and after the treatment, the mean intravaginal ejaculation latency time, the intercourse satisfaction, the mean number of coituses per week and the drug-related side effects were evaluated.

RESULTSThe mean intravaginal ejaculatory latency time was (0.59 +/- 0.12), (3.9 +/- 0.15) minutes (P < 0.001) at baseline and post-treatment in Group A, and (0.56 +/- 0.11), (5.6 +/- 0.12) minutes (P < 0.001) in Group B, improved in both of the 2 groups, but more significantly in Group B (P < 0.05). Before and after the treatment, the mean intercourse satisfaction domain values of the IIEF were (8.9 +/- 1.2), (10.8 +/- 1.1) (P < 0.05) and (8.8 +/- 1.1), (13.8 +/- 1.3) (P < 0.001) in Groups A and B, respectively, significantly greater in Group B than in Group A (P < 0.05) after the treatment; the mean numbers of coituses per week in Groups A and B were (0.9 +/- 0.2), (1.9 +/- 0.3) (P < 0.05) and (1.0 +/- 0.2), (2.7 +/- 0.2) (P <0.001) respectively, significantly larger in Group B (P<0.05) after the treatment. As for the side effects, there was a higher rate of headaches (P < 0.01) and flushing episodes (P < 0.001) in Group B than in Group A.

CONCLUSIONSertraline combined with sildenafil can produce significantly better results than sertraline alone in patients with premature ejaculation. However, the combined treatment is associated with a slight increase in the drug-related side effects.

OBJECTIVETo explore the effects of growth hormone( GH) supplementation on erectile function and expression of nNOS in the intracavernosal nerves in aging rats.

METHODSTwenty male Sprague-Dawley rats aged 18 months were randomly divided into Groups A and B, and ten 2-month-old male Sprague-Dawley rats included in Group C. 1 U/(kg x d) GH was given to Group A, and the same volume of saline to Groups B and C. After 8 weeks of treatment, evaluation was made of the erections induced by apomorphine (APO), maximal intracavernous pressure (ICP) induced by intracavernous papaverine injection and expression of nNOS in the intracavernosal nerves by streptavidin-peroxidase immunohistochemical techniques.

RESULTSAfter 8 weeks of treatment, the erection frequency, maximal ICP and expression of nNOS in the intracavernosal nerves of the rats in Groups A and C were significantly higher than those in Group B (P < 0.05 or P < 0.01).

CONCLUSIONGrowth hormone supplementation can improve the erectile function of aging rats, which may be attributed to the increase in the expression of nNOS in the intracavernosal nerves.
