BACKGROUND:Stand-alone oblique lateral interbody fusion has a high rate of complications of fusion segment sink.Oblique lateral interbody fusion with posterior fixation can provide stable support,but intraoperative position changes and double incisions weaken the advantages of this technique.Oblique lateral interbody fusion combined with lateral plate fixation can achieve one-stage decompression in the same incision,while the lateral internal fixation provides stable support. OBJECTIVE:To analyze the short-term efficacy of oblique lateral interbody fusion combined with lateral plate fixation in the treatment of single-level lumbar degenerative disease. METHODS:The clinical data of 34 patients with single-level lumbar degenerative disease treated with oblique lateral interbody fusion combined with lateral plate fixation were collected from May 2020 to October 2022.Among them,14 were males and 20 were females aged from 41 to 72 years at the mean age of(58.6±9.9)years.There were 11 cases of lumbar spondylolisthesis(Ⅰ°),7 cases of lumbar disc herniation with segmental instability,and 16 cases of lumbar spinal stenosis.Operation time,blood loss,and complications were recorded.Visual analog scale scores of lumbago,radiative pain of both lower limbs,and Oswestry disability index scores were evaluated before surgery,3 months after surgery,and the last follow-up.Dural sac cross-sectional area,intervertebral height,and intervertebral fusion were measured and observed. RESULTS AND CONCLUSION:(1)The 34 patients were followed up for 14-36 months,with an average of(21.3±5.2)months.(2)The operation time ranged from 50 to 92 minutes,with an average of(68.5±11.1)minutes.Intraoperative blood loss was 50-170 mL,with an average of(71.6±25.3)mL.(3)Compared with the preoperative results,the visual analog scale scores and Oswestry disability index scores were significantly decreased at 3 months after surgery and at the last follow-up(P<0.001),and the maximum Oswestry disability index scores were improved by nearly 50%.(4)Bone fusion was achieved in all patients during half-year follow-up.The overall complication rate was 21%(7/34),including 1 case of plate displacement,3 cases of cage subsidence,1 case of psoas weakness,and 2 cases of anterior thigh pain.(5)It is concluded that oblique lateral interbody fusion combined with lateral plate fixation for the treatment of lumbar degenerative diseases has the characteristics of less blood loss,short operation time,rapid postoperative recovery,and significant short-term clinical efficacy with the stable support to a certain extent.The long-term curative effect needs further follow-up observation.

OBJECTIVE:
To compare the efficacy of percutaneous pedicle screw combined with unilateral nail placement combined with bone cement strengthening and bilateral nail placement in the treatment of osteoporotic thoracic and lumbar fractures.
METHODS:
A retrospective case-control study was used to analyze the clinical data of 78 patients with osteoporotic thoracic and lumbar fractures admitted from October 2017 to May 2019. According to the surgical method, it was divided into percutaneous pedicle screw combined with unilateral nail placement combined with unilateral bone cement strengthening group(bone cement group) and percutaneous pedicle screw combined with bilateral nail placement(screw group). In the bone cement group, 40 patients included 16 males and 24 females, with a mean age of (62.1±8.1) years old. In the screw group, 38 patients included 18 males and 20 females with a mean age of (65.1±9.3) years old. The operation time, intraoperative blood loss, length of hospital stay and postoperative complications were compared between two groups. The kyphosis Cobb angle, anterior edge height ratio, central height ratio and pain visual analogue score(VAS) were compared.
RESULTS:
All patients were followed up for 25 to 36 months. The operation time (70.1±17.3) min of the cement group was shorter than that of the screw group (78.6±18.2) min(P<0.05). There were no significant differences in intraoperative blood loss and length of hospital stay(P>0.05). The VAS in the cement group 1 year 1.5±0.5 and the latest follow-up 0.5±0.3 after operation were lower than 1 year 1.8±0.3 and the latest follow-up 0.8±0.4 in the screw group(P<0.05). The kyphosis Cobb angle, anterior edge height ratio, central height ratio in bone cement group, 1 year (6.2±1.2)°, (86.6±3.5)%, (91.1±2.5)%, the last follow-up (6.4±0.7)°, (85.5±3.3)%, (90.5±6.3)% were better than that of the screw group 1 year (6.8±1.4)°, (83.1±2.4)%, (89.9±3.4)% and the latest follow-up (7.1±1.1)°, (82.6±4.1)%, (87.6±5.9)%(P<0.05). There were 3 cases of bone cement leakage in the cement group, all of which had no clinical symptoms;and 2 cases of pedicle screws were extracted in the screw group, and the screws were removed at the last follow-up.
CONCLUSION
Percutaneous pedicle screw combined with unilateral nail placement combined with bone cement strengthening and bilateral nail placement in the treatment of osteoporotic thoracic and lumbar compression fractures in the elderly can achieve satisfactory efficacy and effectively relieve the pain of patients, but the former internal fixation system is more stable, and the long-term follow-up can effectively maintain the height of the anterior middle column and the correction of kyphosis deformity, and the incidence of chronic low back pain is lower.

OBJECTIVE:
To explore clinical effect of autologous osteochondral transplantation (AOT) in the treatment of recurrent anterior dislocation of the shoulder joint with glenoid cartilage defect in rabbits by establishing a model of recurrent anterior dislocation of the shoulder joint with < 20% glenoid cartilage defect in rabbits.
METHODS:
Twenty-four male New Zealand white rabbits, aged 6-month-old, weighed (2.69±0.17) kg were selected. The labrum of shoulder joint of rabbits was artificially destroyed to establish a model of recurrent anterior dislocation of shoulder joint with cartilage defect. They were divided into AOT surgery group and simple suture group, with 12 rabbits in each group. AOT group were underwent AOT surgery, while simple suture group was treated with simple Bankart suture for recurrent shoulder joint dislocation. At 6 and 12 weeks after operation, 6 rabbits between two groups were sacrificed for sampling. The dietary conditions, activity conditions, mental states of rabbits and healing conditions of grafts in the specimens were observed and compared between two groups. HE staining was used to observe cell creep, cell morphology, inflammatory cell infiltration, fibrochondrocytes and their arrangement. Masson staining was used to observe the formation and arrangement of collagen fibers; Safrane-green staining was used to observe the regeneration of articular cartilage, subchondral bone and bone tissue. Bone mineral density (BMD), bone volume (BV) and trabecular thickness (Tb.Th) between two groups were measured by Micro-CT to evaluate the remodeling of shoulder glenoid bone defects by autologous osteochondral cartilage.
RESULTS:
After different surgical interventions were carried out in both groups of rabbits, at 6 weeks after the operation, the abduction, extension, internal rotation and external rotation of the shoulder joint on the operated side showed limited range of motion compared with the contralateral side, while adduction and forward flexion showed no obvious abnormalities compared with the contralateral side. At 12 weeks after operation, the range motion of tshoulder joints in both groups of rabbits had returned to the state before modeling. The effects of HE staining, Masson staining and safrane-green staining at 12 weeks after operation in both groups were stronger than the staining results at 6 weeks after operation. Moreover, the results of HE staining, Masson staining and safranin fixation green staining in AOT group at 6 and 12 weeks after operation were all higher than those in simple suture group. Micro-CT scan results at 6 and 12 weeks after operation showed that BMD (0.427±0.014), (0.466±0.032) g·cm-3, BV(116.171±3.527), (159.327±3.500) mm3, and Tb.Th (0.230±0.006), (0.285±0.009) mm in AOT group, which were higher than those of simple suture group in BMD(0.358±0.011), (0.384±0.096) g·cm-3, BV(72.657±3.903), (118.713±3.860) mm3, and Tb.Th(0.204±0.009), (0.243±0.007) mm;and the differences were statistically significant (P<0.05).
CONCLUSION
AOT procedure could effectively promote osteogenesis and fibrocartilage regeneration in the cartilage defect area of the shoulder glenoid <20%, which is conducive to reshaping the structure of the shoulder glenoid.

Extensive studies have identified potential adverse effects on semen quality of obesity, based on body mass index, but the association between body fat distribution, a more relevant indicator for obesity, and semen quality remains less clear. We conducted a longitudinal study of 4304 sperm donors from the Guangdong Provincial Human Sperm Bank (Guangzhou, China) during 2017-2021. A body composition analyzer was used to measure total and local body fat percentage for each participant. Generalized estimating equations were employed to assess the association between body fat percentage and sperm count, motility, and morphology. We estimated that each 10% increase in total body fat percentage (estimated change [95% confidence interval, 95% CI]) was significantly associated with a 0.18 × 10 6 (0.09 × 10 6 -0.27 × 10 6 ) ml and 12.21 × 10 6 (4.52 × 10 6 -19.91 × 10 6 ) reduction in semen volume and total sperm count, respectively. Categorical analyses and exposure-response curves showed that the association of body fat distribution with semen volume and total sperm count was stronger at higher body fat percentages. In addition, the association still held among normal weight and overweight participants. We observed similar associations for upper limb, trunk, and lower limb body fact distributions. In conclusion, we found that a higher body fat distribution was significantly associated with lower semen quality (especially semen volume) even in men with a normal weight. These findings provide useful clues in exploring body fat as a risk factor for semen quality decline and add to evidence for improving semen quality for those who are expected to conceive.

OBJECTIVE:
To explore the clinical characteristics and prognostic factors of patients with extranasal NK/T-cell lymphoma (NKTCL).
METHODS:
The clinical data of 138 patients with NKTCL diagnosed in 10 medical centers of Huaihai Lymphoma Working Group from June 2015 to April 2021 were collected and analyzed retrospectively. The differences in clinicopathological characteristics of patients with different involvement and efficacy of pegaspargase regimen were compared, as well as perform survival analysis.
RESULTS:
A total of 138 extranasal NKTCL patients were included, with a median age of 46 years, and the ratio of males to females was approximately 2∶1. There were 39 patients with gastrointestinal involvement, 32 patients with oropharyngeal involvement, 17 patients with skin involvement, 11 patients with lymph node involvement, 11 patients with orbital involvement, and 28 patients with other parts involvement. Patients with skin involvement had a higher proportion of advanced disease and a lower proportion of CD56 positive rate compared to those with oropharyngeal involvement. Among the patients with gastrointestinal involvement, the survival rate of patients who received pegaspargase regimen was significantly higher than those who were treated without pegaspargase (P < 0.01). Multivariate analysis showed that serum creatinine was an independent prognostic factor for patients with skin involvement ( HR =1.027, 95%CI : 1.001-1.054, P =0.040), ECOG PS and EBV DNA were independent prognostic factors for patients with gastrointestinal involvement ( HR =2.635, 95%CI : 1.096-6.338, P =0.030; HR =4.772, 95% CI : 1.092-20.854, P =0.038), and ECOG PS and CA stage were independent prognostic factors for patients with oropharyngeal involvement ( HR =13.875, 95%CI : 2.517-76.496, P =0.002; HR =20.261, 95%CI : 2.466-166.470, P =0.005).
CONCLUSION
The clinicopathological characteristics of extranasal NKTCL patients with different sites of involvement are vary, and effective individualized treatment need to be further explored.

OBJECTIVE To build a Tibetan-language medication service platform based on “internet+” and evaluate its effect on improving medication compliance and safety of Tibetan patients with chronic disease. METHODS Medication guidance contents of commonly used drugs in the outpatient department were summarized, translated and recorded in Tibetan-language or video to form a “text-audio-video” multi-dimensional “internet+ ” Tibetan-language medication service platform. A total of 387 Tibetan outpatients with chronic disease in our hospital after the implementation of “internet+” Tibetan-language medication service platform (from January 2024 to June 2024) in our hospital were selected as the intervention group, and 387 Tibetan outpatients before the implementation (from January 2023 to June 2023) were selected as the control group. Patients in the control group received conventional window-based Chinese-language medication services, while patients in the intervention group received both conventional window-based Chinese-language medication service and “internet+ ” Tibetan-language medication service. The medication compliance of patients was evaluated using the 12-item Medication Compliance Scale. A six-level causality assessment was conducted as the principles for analyzing adverse drug reactions (ADR) set by the National Center for ADR Monitoring. Additionally, statistics were compiled on the occurrence of ADR that were assessed as “definite”“probable” or “possible” in the causality assessment. RESULTS The proportion (31.0%) of patients with good medication compliance and compliance scores [39.0 (37.0,42.0)] of patients in the intervention group were significantly better than control group [7.0%, 21.0(19.0, 23.0)]( P<0.05). There were no statistically significant differences in the incidence of various types of ADR or the overall incidence between the two groups (P>0.05). CONCLUSIONS The “internet+” Tibetan-language medication service platform is constructed successfully; the service can effectively improve the medication compliance of Tibetan-language patients, but its effect on improving the medication safety of patients is limited.

Objective:
To investigate the effects of fine particulate matter (PM2.5) exposure on acute myocardial infarction (AMI) mortality and years of life lost (YLL).
Methods:
Mortality data in Haizhu District, Guangzhou City from 2020 to 2024 were collected by the China Population Death Information Registration Management System and Guangdong Death Certificate Management System. Air pollution and meteorological data of the same period were obtained from the national environmental monitoring sites on the National Real-time Air Quality Release Platform and the Guangzhou Observatory, respectively. The single-pollutant model and multi-pollutant model were established by distributed lag non-linear model to analyze the effects of PM2.5 on AMI mortality and YLL.
Results:
From 2020 to 2024, there were 2 466 AMI death cases in Haizhu District, including 949 males and 1 517 females. Among them, 530 cases were aged <65 years, 494 cases were aged 65-74 years, and 1 442 cases were aged >74 years. The median daily average number of deaths was 1.3 (interquartile range, 2.0) cases, and the median daily average YLL was 16.4 (interquartile range, 24.8) person years. The median daily average mass concentration of PM2.5 was 24.3 (interquartile range, 18.0) μg/m3. In single-pollutant models, the maximum effects of PM2.5 on AMI mortality and YLL were observed at a cumulative lag of 7 days. For per 10 μg/m3 increment in the daily average concentration of PM2.5, the excess risk of AMI mortality increased by 8.793% (95%CI: 4.201% to 13.588%), and YLL increased by 2.059 (95%CI: 1.081 to 3.037) person-years. Gender-stratified analyses showed that PM2.5 significantly affected AMI mortality in males and YLL in males and females (all P<0.05). Age-stratified analyses revealed that PM2.5 significantly affected AMI mortality and YLL among residents aged <65 years and 65-74 years (all P<0.05). However, the difference between genders or the two age groups was not statistically significant (both P>0.05). In multi-pollutant models, when NO2, SO2, or O3 were introduced respectively at a cumulative lag of 7 days, the effects of PM2.5 on AMI mortality and YLL were enhanced compared to the single-pollutant model (all P<0.05). When PM10 was introduced alone or in combination with PM10, SO2, NO2, and O3, the effects of PM2.5 on AMI mortality and YLL were not statistically significant (all P>0.05).
Conclusion
Exposure to PM2.5 may increase the risk of AMI mortality and YLL, with varying effects across populations of different genders and ages.

The mechanism of L-perilla alcohol(L-POH) in intervening hypoxic pulmonary hypertension(HPAH) was discussed based on network pharmacology, and experimental verification. The active components and potential targets of the volatile oil of Rhodiola tangutica(VORA) in the intervention of HPAH were screened by network pharmacology. The biological process of Gene Ontology(GO) and the signaling pathway enrichment of Kyoto Encyclopedia of Genes and Genomes(KEGG) were analyzed for the core targets, and a "component-common target-disease" network was constructed. Four active components were screened from VORA: L-POH, linalool, geraniol, and(-)-myrtenol. The core targets for treating HPAH were HSP90AA1, AKT1, ESR1, PIK3CA, EP300, EGFR, and JAK2. GO enrichment analysis mainly involved biological processes such as reaction to hypoxia, heme binding, and steroid binding. KEGG enrichment analysis mainly involved hypoxia-inducing factor 1(HIF-1) signaling pathway, phosphatidylinositol 3-kinase/protein kinase B(PI3K/AKT) signaling pathway, and Janus kinase/activator of signal transduction and transcription(JAK/STAT) signaling pathway. The vasodilation effects of the four active components were screened by perfusion experiment of extracorporeal vascular rings, and the mechanism of the main active component L-POH was studied by channel blockers. The inhibitory effects of the four active components on the proliferation of pulmonary artery smooth muscle cells(PASMCs) induced by hypoxia were screened by cell proliferation experiment, and the mechanism of the main active component L-POH was studied by flow cytometry, cell cycle experiment, and Western blot. The results showed that L-POH could directly act on vascular smooth muscle to relax pulmonary arterioles, induce ATP-sensitive potassium channels to open, and inhibit extracellular Ca~(2+) influx through voltage-gated calcium channels to relax blood vessels. In addition, L-POH could inhibit the abnormal proliferation of PASMCs induced by hypoxia and promote its apoptosis, and its mechanism may be related to the increase in Bax protein expression and the decrease in p-JAK2, p-STAT3, Bcl-2, and cyclinA2 protein expression. In summary, L-POH can interfere with HPAH by relaxing pulmonary arterioles and inhibiting the proliferation of smooth muscle cells.
