This article reviews the mechanism, clinical medication regimens, drug interactions and adverse reactions of five small molecule antiviral drugs currently approved for marketing in China, so as to provide advice for the clinical rational use of anti-SARS-CoV-2 in the elderly.
RESUMEN
Aim To explore the mechanism of the natural phenolic compound pterostilbene(PTE)in the protection of liver ischemic/reperfusion. Methods A total of 40 C57 mice were divided into control group,model group,drug delivery group and treatment group and a 70% liver ischemic/reperfusion(ischemic 60 min)model was established,then primary LSECs were isolated by perfusion and digestion. Hepatic structural disruption was observed by HE staining. The ultrastructure of hepatic sinus endothelial cells was observed by transmission electron microscopy(TEM). The structure of LSECs fenestrae was observed by scanning electron microscopy(SEM). The expression level of heme oxygenase 1(HO-1)in LSECs was detected by Western blot. Results HE staining showed that PTE protected against hepatic ischemic injury. TEM observed that PTE had a protective effect on hepatic sinus endothelial cells,and the number of LSECs fenestrae in the blank control group was larger and the number of fenestrae in the liver I/R model group was reduced. The number of LSECs fenestrae in the liver I/R model group treated with PTE increased compared with the untreated liver I/R model group. Western blot result showed that PTE was able to induce HO-1 expression in LSECs. Conclusions PTE alleviates oxidative damage of endothelial cells in mouse hepatic sinus by inducing HO-1expression,and protects the liver from ischemia/reperfusion injury.

All patients were divided into two groups according to different surgical methods. Among them, 200 patients used interspinous process fusion and distraction fixation (ISDFF group), the other 200 cases used posterior lumbar decompression and pedicle internal fixation (PLIF group). All patients completed the follow-up time of more than 1 year after operation. The basic information of patients′ age, gender, total number of days in hospital, intraoperative bleeding, operation time, surgical incision length and other basic information were observed. The Oswestry dysfunction index (ODI), the Japanese Orthopaedic Association Score (JOA) and the visual analog scale (VAS) were used to evaluate the relief of symptoms before and after the two groups of patients. Total medical expenses, anesthesia expenses, surgical expenses and other expenses were analysed. The software of SPSS 20.0 were conducted to analyze data.Results:The patients in the ISDFF group were (70.84±8.93) years old, and the PLIF group was (65.10±10.23) years old ( t=5.98, P=0.008). The operation time in the ISDFF group was (59.21±16.22) min, and the operation time in the PLIF group was (81.31±17.24) min( t=13.20, P<0.001). The bleeding volume of the ISDFF group was (33.24±11.31) mL, and the bleeding volume of the PLIF group was (67.30±17.61) mL ( t=23.02, P<0.001). The length of the surgical incision in the ISDFF group was (8.27±2.53) cm, and the length of the surgical incision in the PLIF group was (11.15±1.91) cm ( t=11.848, P<0.001). The total hospitalization time in the ISDFF group was (15.15±0.54) days, and the total hospitalization time in the PLIF group was (19.86±0.97) days( t=4.26, P<0.001). There was no significant difference in preoperative ODI, JOA and VAS between the two groups ( P>0.05). Symptoms of postoperative patients were significantly improved compared with preoperative. There were statistical differences in ODI, JOA and VAS between the two groups before and after operation ( P<0.05). However, ODI, JOA and VAS were no statistical difference between the two groups after operation. Complications occurred in 5 cases of the two groups of patients, including two cases of superficial infection in the PLIF group, two cases of dural tear in the PLIF group, one case of spinous process fracture in the ISDFF group. The total hospitalization fee for ISDFF was (57 450±8 670) (yuan), and the total hospitalization fee for PLIF was (75 770±1 640) (yuan), with statistical differences ( t=9.92, P<0.001). The cost of ISDFF operation was 1864±38.19 (yuan), and the cost of PLIF operation was 2352±41.39 (yuan) ( t=8.65, P<0.001). ISDFF antibacterial drug usage fee was 635.5±64.69 (yuan), PLIF antibacterial drug usage fee was 1449±307.1 (yuan) ( t=2.59, P<0.001). The one-time medical material cost during the ISDFF operation was (38 990±300) (yuan), and the one-time medical material cost during the PLIF operation was (52 110±150) (yuan) ( t=5.88, P<0.001). The excellent and good rate of ISDFF group was 92%, and that of PLIF group was 86%. In this study, the total cost of hospitalization was used as an indicator to measure the cost, and further cost-effectiveness evaluation was made. For every good patient, the cost of the ISDFF group was 62 450 yuan, and the cost of the PLIF group was 88, 100 yuan. Conclusions:ISDFF is beneficial to reduce the cost of medical insurance in China, which is in line with the direction of national reform to reduce medical expenditure. It is a surgical method worthy of wide promotion and has a good application prospect.
RESUMEN
Objective:To study the efficacy and safety of bone-filling mesh container plasty in the treatment of posterior wall fracture of vertebra caused by spinal metastases.Methods:This study is a retrospective analysis of 65 patients with pathological fractures of the vertebra caused by vertebral metastases treated with bone-filling mesh container plasty from January 2015 to December 2019. There were 21 males and 44 females, 70.3±10.8 (46-90) (years). According to primary tumor, there were 25 cases of lung cancer, 14 cases of breast cancer, 11 cases of digestive system cancer, 13 cases of urinary system cancer, 1 case of lymphoma and 1 case of ovarian cancer. In the segment of vertebral metastases, there were 2 cases of T 2 vertebra, 1 case of T 5 vertebra, 1 case of T 6 vertebra, 2 cases of T 8 vertebra, 1 case of T 9 vertebra, 5 cases of T 10 vertebra, 4 cases of T 11 vertebra, 15 cases of T 12 vertebra, 12 cases of L 1 vertebra, 8 cases of L 2 vertebra, 8 cases of L 3 vertebra, 4 cases of L 4 vertebra, and 2 cases of L 5 vertebra. According to the CT images of the patient's vertebra before operation, the area of the damaged posterior wall of the vertebra is measured as s, and the area of the posterior wall of the intact vertebra is measured as S. The ratio of posterior wall damage is calculated as R= s/ S, and the value of R represents the degree of damage to the posterior wall of the vertebra. According to the size of the R value, the patients were divided into four groups, typeⅠ( R≤25%, 21 cases), typeⅡ(25%< R≤50%, 22 cases), typeⅢ (50%< R≤75%, 14 cases), typeⅣ( R>75%, 8 cases). The visual analog scale (VAS), Oswestry disability index (ODI) and activity of daily living (ADL) before and 1 day after surgery, 1 month after surgery, and 3 months after surgery were analyzed and compared to evaluate the efficacy of bone-filling mesh container plasty. Pairwise comparisons were performed to verify whether there is a difference in efficacy, bone cement leakage and postoperative complications. Results:All 65 patients were followed up for 3-6 months, with an average of 3.8 months. The VAS scores before surgery, postoperative day 1, postoperative 1, 3 months were 7.32±0.99, 4.14±1.06, 4.11±0.97, and 4.34±1.11, respectively, with a statistically significant difference ( F=149.20, P<0.001). ODI of preoperative, postoperative day 1, postoperative 1, and 3 months were 69.45%±4.15%, 36.65%±3.72%, 36.84%± 3.38%, 37.78%±3.45%, respectively, with a statistically significant difference ( F=840.88, P<0.001). ADL score of preoperative, postoperative day 1, postoperative 1, and 3 months were 71.31±12.81, 79.85±9.14, 78.92±8.95, and 78.31±8.67, respectively, with a statistically significant difference ( F=149.20, P<0.001). There was no significant difference in VAS, ODI and ADL scores between types I and IV (all P>0.05), but with the increase of R value, the leakage rate of intraspinal bone cement would increase correspondingly. Eleven cases occurred bone cement leakage with the rate of 17%. The leakage rate of type I and II was 0, type III was 7.1% (1/14), and type IV was 37.5% (3/8). All patients did not have systemic complications such as allergies, shock, decreased oxygen saturation, etc., and there were no bleeding, infection, nerve root symptoms or cement insertion syndrome after surgery. Conclusion:Bone-filling mesh container plasty can significantly improve the pain symptoms of patients with spinal metastases and recovery functions. The degree of damage to the posterior vertebra has no effect on the efficacy of the surgery. As the degree of damage to the posterior wall of the vertebra increases, the risk of complications of bone cement leakage in the spinal canal will increase.
RESUMEN
Objective:To evaluate the efficacy of percutaneous curved kyphoplasty (PCKP) for the treatment of osteoporotic vertebral compression fracture (OVCF).Methods:A retrospective cohort study was conducted to analyze the clinical data of 70 patients with OVCF admitted to Third People′s Hospital of Datong from May 2020 to December 2021, including 32 males and 38 females, aged 60-89 years [(73.0±8.7)years]. The patients were treated with PCKP (PCKP group, n=20) or percutaneous vertebroplasty (PVP) (PVP group, n=50). The operation time, intraoperative blood loss, length of hospital stay, excellent rate of bone cement distribution at postoperative 1 day, and leakage rate of bone cement were compared between the two groups. In addition, anterior height ratio of the injured vertebrae, upper and lower Cobb angle, visual analogue scale (VAS), and Oswestry dysfunction index (ODI) were measured preoperatively and at postoperative 24 hours and 3 months. Results:All patients were followed up for 3-4 months [(3.0±0.6)months]. There were no significant differences in the operation time, intraoperative blood loss, and length of hospital stay between the two groups (all P>0.05). At postoperative 1 day, the excellent rate of bone cement distribution was 100% in PCKP group (excellent in 13 patients, good in seven, poor in zero), significantly higher than 82% in PVP group (excellent 21 patients, good in 20, and poor in nine). The leakage rate of bone cement was 0%(0/20) in PCKP group, lower than 20% (10/50) in PVP group ( P<0.05). There were no significant differences in the anterior height ratio of injured vertebrae, upper Cobb angle, lower Cobb angle, VAS and ODI between the two groups before operation (all P>0.05). At postoperative 1 day, PCKP group showed significantly higher anterior height ratio of injured vertebrae and significantly lower upper Cobb angle, lower Cobb angle, VAS, and ODI than those in PVP group ( P<0.05 or 0.01). At postoperative 3 months, PCKP group still showed significantly higher anterior height ratio of injured vertebrae and significantly lower upper Cobb angle and lower Cobb angle than those in PVP group ( P<0.05 or 0.01), but there was no significant difference in VAS and ODI between the two groups (all P>0.05). In PCKP group, the anterior height ratio of the injured vertebrae was significantly increased and the upper Cobb angle, lower Cobb angle, VAS, and ODI index were significantly decreased at postoperative 1 day and 3 months when compared with those before operation (all P<0.05). In PVP group, there were no significant changes in the anterior height ratio of the injured vertebrae, upper Cobb angle, and lower Cobb angle at postoperative 1 day and 3 months when compared with those before operation (all P>0.05), but the VAS and ODI were significantly lowered at postoperative 1 day and 3 months when compared with those before operation (all P<0.05). Conclusion:Compared with PVP, PCKP has better diffusion effect of bone cement in the injured vertebrae and lower incidence of bone cement leakage in the treatment of OVCF, which can effectively promote height recovery of the injured vertebrae, relieve the pain early, and improve spinal function.
RESUMEN
The implantation of interspinous process device is a minimal invasive surgical procedure for degenerative lumbar spinal diseases. At present, a variety of interspinous process devices designed can be subdivided into three categories based on different application principles: interspinous distraction device, interspinous fixation device and interspinous fusion device. The interspinous distraction devices distract interspinous interspace, enlarge spinal canal area and alleviate neurological symptom, which are mainly applied for lumbar spinal stenosis with intermittent neurogenic claudication. Interspinous fixation device has been used as an alternative technique to the pedicle screw fixation in lumbar interbody fusion due to gripping and fixating to spinous process. Interspinous fusion device utilizes rigid fixation to support fusion, which can be used as not only simple distraction device but also additional instrumentation for direct decompression and interbody fusion. All types of interspinous process devices are different in biomechanical characteristics due to its application concept. In this review, the author mainly focus on biomechanical research progress of interspinous process device in lumbar degenerative disease.

Objective:To evaluate the clinical effect of interspinous process fusion (BacFuse) in the treatment of lumbar disc herniation (LDH) with rheumatoid arthritis (RA).Methods:A retrospective analysis of the clinical data of 50 patients with RA and LDH from May 2013 to June 2018 in department of orthopedics, Beijing Friendship Hospital, Capital Medical University was conducted. Among them, there were 9 males and 41 females, aged (66.60±4.23) years, with an age ranging from 54 to 84 years. According to different surgical methods, the patients were divided into posterior lumbar interbody fusion (PLIF) group ( n=26) and BacFuse group ( n=24). Operative time, intraoperative blood loss and operative complications of the two groups were observed. Oswestry disability index (ODI) and Japanese Orthopaedic Association (JOA) scores were used to evaluate the clinical effect at preoperative, 3 days of postoperative and the last follow-up. The measurement data were expressed as mean±standard deviation( Mean± SD), comparison between groups used t test and the count data were expressed as percentage(%), the chi-square test was used for comparison between the two groups. The clinical effect of the two groups were compared by repeated analysis of variance. Results:In the PLIF group, the operation time and bleeding volume were (174.62±55.59) min, (309.62±30.26) mL, respectively. In the BacFuse group, the operation time and bleeding volume were (71.25±12.96) min, (57.92±9.32) mL, respectively. The differences between the two groups were statistically significant ( P<0.05). The operative complications in the PLIF group (8 cases) was significantly higher than that in the BacFuse group (2 cases) , the difference between the two groups was statistically significant ( χ2 = 3.926, P=0.048). There were significant differences between every two scores among the preoperative, 3 days of postoperative and last follow-up in ODI of the PLIF group( F=760.231, P<0.001). The preoperative, 3 days of postoperative and last follow-up ODI scores of the BacFuse group were significant differences between every two scores ( F= 952.525, P<0.001). There were no significant differences in ODI scores between the two groups [( t=-1.13, P=0.263), ( t=0.706, P=0.483), ( t=0.389, P=0.699)]. There were significant differences between every two scores among the preoperative, 3 days of postoperative and last follow-up in JOA of the PLIF group( F=406.012, P<0.001). The preoperative, 3 days of postoperative and last follow-up in JOA scores of the BacFuse group were significant difference between every two scores ( F=457.760, P<0.001). There were no significant differences in JOA scores between the two groups [( t=0.825, P=0.414), ( t=1.909, P=0.062), ( t=1.086, P=0.283). Conclusions:Compared with PLIF, BacFuse has a similar clinical effect in the treatment of LDH with RA, but BacFuse is less invasive and has fewer postoperative complications. BacFuse is an effective minimally surgical method for the treatment of LDH with RA.
RESUMEN
Objective:To compare the clinical outcomes of percutaneous vertebroplasty (PVP) and the Vesselplasty for kümmell′s disease.Methods:A retrospective case-control study was used.The clinical data of 62 patients with kümmell′s disease were selected in Beijing Friendship Hospital, Capital Medical University, from January 2017 to January 2019. There were 19 males and 43 females, aged (70.94±7.69) years, with range from 60 to 85 years. The patients were divided into two groups according to different operation methods. The 36 patients treated by PVP and 26 patients treated by Vesselplasty were followed up at least one year after operation. The follow-up time was (17.55±4.22) months. The operation time, incidence of cement leakage, preoperative and postoperative Cobb′s angle, visual analogue score (VAS) 1 week and 1 year after operation were observed. The measurement data were expressed as mean±standard deviation ( Mean± SD), independent sample t-test was used for comparison between groups. The count data were expressed as percentage (%), chi-square test was used for comparison between groups. Results:All the operation was successfully completed. No serious complications such as paraplegia, bone cement allergy, pulmonary embolism were occurred. The operation time was no significant difference between the two groups ( P< 0.05). The incidence of cement leakag was 41.67% (15/36) in PVP group and 11.54% (3/26) in Vesselplasty group. The latter was significantly lower than the former, with statistically significant differences between the two groups ( P< 0.05). In PVP group, the Cobb′s angles of preoperation, postoperation 1 year and difference were (26.23 ± 5.62)°, (17.46 ± 3.01)° and (8.78 ± 4.62)°, respectively, in Vesselplasty group, they were (28.74 ± 6.68)°, (16.68 ± 2.79)° and (12.07 ± 5.72)°, respectively. Cobb′s angle of the two groups was significantly improved after operation. In the comparison between the groups, the improvement of the Cobb′s angle in the Vesseplasty group was better than that of the PVP group, and the difference was statistically significant ( P< 0.05). The VAS score in PVP group was (8.42±1.03) scores in preoperation, (3.06±1.01) scores in 1 week, (0.81±0.75) scores in 1 year. The VAS score in Vesselplasty group was (8.35±1.02) scores in preoperation, (2.88±1.11) scores in 1 week and (1.04±0.87) scores in 1 year. Compared with pre-operation, the VAS scores of the two groups decreased significantly at 1 week and 1 year after operation, and the difference was statistically significant ( P<0.05). There was no significant difference in VAS between groups 1 week after operation and 1 year after operation ( P>0.05). Conclusion:Vesselplasty can effectively control the flow and distribution of bone cement in the vertebral body, effectively reduce the leakage of bone cement, and better correct kyphosis.
RESUMEN
Abstract Pulmonary segmentectomy refers to the anatomic resection of lung parenchyma, which isolates bronchopulmonary from terminal bronchus to hilum after cutting the pulmonary artery, vein, and bronchus. It has been applied in the treatment of primary lung cancer, metastatic lung cancer, and other benign lesions because of the surgical techniques, such as lesion localization and recognition of the intersegmental plane. The pulmonary function of patients after pulmonary segmentectomy has been decreased to different degrees due to various factors, which may ultimately determine the overall prognosis and postoperative quality of life. This review will conclude the main techniques of pulmonary segmentectomy and its effect on lung function.

It has been applied in the treatment of primary lung cancer, metastatic lung cancer, and other benign lesions because of the surgical techniques, such as lesion localization and recognition of the intersegmental plane. The pulmonary function of patients after pulmonary segmentectomy has been decreased to different degrees due to various factors, which may ultimately determine the overall prognosis and postoperative quality of life. This review will conclude the main techniques of pulmonary segmentectomy and its effect on lung function.
RESUMEN
OBJECTIVE@#To investigate the related factors of adverse reactions of blood transfusion, and clinical precautions so as to reduce the adverse reactions.@*METHODS@#Data of 2108 patients with allogeneic transfusion in our hospital from January 2017 to June 2017 collected and analyzed.@*RESULTS@#These patients received 15 244 time of blood transfusion, and 213 time of adverse reactions occurred in 178 patients in totality, the incidence is 1.4%, and there was no significant difference between the male (1.31%) and female (1.53%). The main type of transfusion reaction were allergy (73.23%), FNHTR (11.74%) and TACO (10.80%). Among all kinds of blood components, the incidence of adverse reactions of apheresis platelet transfusion was the highest (4.31%), significantly higher than that of cryoprecipitate and other blood components. The incidence rate of adverse reactions of blood transfusion in the hematopathy patients was 2.56%, significantly higher than that of immune diseases (1.48%), cancer diseases (1.28%) and other diseases (1.08%), (P＜0.01). The rate of transfusion history of apheresis platelets was 42.67% (the incidence of adverse reactions was 4.31%), significantly higher than other groups (P＜0.01); the rate of transfusion history of cryoprecipitate was 4.11% (the incidence of adverse reaction was 0.45%), significantly lower than other groups (P＜0.05). Among the disease types, the rate of transfusion history in the hematopathy patients was 48.79% (the incidence of adverse reaction was 2.56%), significantly higher than that of other groups (P＜0.01). The incidence of drug allergy in patients with the adverse reactions to blood transfusion was 11.25%, significantly higher than that of patients without adverse reactions (4.71%) (P＜0.01).@*CONCLUSION@#The main risk factors of adverse reactions of blood transfusion are as follows: blood varieties, disease type, transfusion history and drug allergy history. For the patients with transfusion, multiple factors should be controlled, so as to reduce the adverse reactions.

Objective@#To compare the clinical outcomes of unilateral extreme extrapedicular puncture versus bilateral transpedicular puncture in percutaneous vertebroplasty (PVP) for osteoporotic vertebral compression fracture.@*Methods@#A prospective cohort study was performed. Ninety-seven patients of osteoporotic vertebral compression fractures treated were selected from January 2016 to January 2018 in Beijing Friendship Hospital, Capital Medical University. There were 36 males and 61 females, aged (72.19±7.41) years, with an age range of 60-80 years. All the patients underwent PVP with different puncture methods were divided into unilateral puncture group(n=52) and bilateral puncture group(n=45). PVP was performed in the unilateral extreme extrapedicular puncture group by unilateral puncture of the pedicle, and PVP was performed by bilateral puncture of the pedicle in the bilateral transpedicular puncture group. All patients completed at least one year of follow-up after operation. The operation time, fluoroscopy times, cement volume, incidence of cement leakage, visual analogue score (VAS) of 1 week and 1 year after operation were observed. The measurement data were expressed as mean±standard deviation (Mean±SD), count data were expressed as percentage, the independent sample t test and the χ2 test were used for comparison between groups, and the paired t test was used for comparison within the group.@*Results@#The operation was successfully completed in both groups. No serious complications such as paraplegia, bone cement allergy, pulmonary embolism were occurred. In the unilateral puncture group, the operation time were (21.90±3.16) min, the fluoroscopy times were (15.46±2.86) times, the cement volume were (3.47±0.41) ml and the incidence of cement leakage was 44.23% (23/52), in the bilateral puncture group, the operation time were (31.64±6.90) min, the fluoroscopy times were (23.31±2.39) times, the cement volume were (4.66±0.61) ml and the incidence of cement leakage was 68.89% (31/45). The operation time, fluoroscopy times, cement volume and incidence of cement leakage of unilateral puncture group were significantly less than those of bilateral puncture group. The difference was statistically significant (P< 0.05). The VAS score in unilateral puncture group was (8.18±0.77) scores in preoperation, (3.39±0.69) scores in 1 week, (1.07±0.90) scores in 1 year. The VAS score in bilateral puncture group was (7.93±0.92) scores in preoperation, (3.14±0.83) scores in 1 week and (0.90±0.82) scores in 1 year. Compared with pre-operation, the VAS scores of the two groups decreased significantly at 1 week and 1 year after operation, and the difference was statistically significant (P<0.05). However, there was no significant difference in VAS between groups at 1 week after operation and 1 year after operation (P>0.05).@*Conclusions@#Compared with bilateral transpedicular puncture, PVP through unilateral extrapedicular puncture can achieve the same clinical effect. However, the latter can significantly reduce the operation time, the cement volume, fluoroscopy times and the incidence of cement leakage.
RESUMEN
Lung cancer is the leading cause of death in malignant tumors. Surgery is one of the main treatments for early stage lung cancer. Idiopathic pulmonary fibrosis (IPF), one of the most common interstitial lung disease, is a chronic, progressive lung disease, characterized by insidious onset and progressive deterioration. It is reported that there are common pathways in idiopathic pulmonary fibrosis and lung cancer, and patients with IPF have a higher risk of lung cancer than the general population, whose prevalence was 3.34 times than that of the general population. The incidence of acute exacerbations of IPF and postoperative mortality was significantly higher in lung cancer patients complicated with IPF than those without IPF. The long-term outcomes of patients with IPF are dramatically worse than those without IPF. It was concluded that lobectomy has been still the standard surgical procedure for such patients, but sublobectomy should be taken as potential alternative choice for patients with high risk after preoperative evaluation. Moreover, further studies should be conducted on the prevention and treatment of acute exacerbation of IPF after surgery.
RESUMEN
Objective To summarize the experience of anterolateral percutaneous vertebroplasty (PVP) in the treatment of cervical metastases in advanced lung cancer,and to evaluate its therapeutic effect on patients with cervical metastases in advanced lung cancer.Methods A total of 27 patients with advanced cervical spine metastases were enrolled from July 2009 to September 2018 in Department of Orthopaedics,Beijing Friendship Hospital,Capital Medical University.A retrospective analysis was performed on 20 patients who underwent PVP and had complete follow-up data.There were 12 males and 8 females,aged (59.15±7.55) years.A total of 32 cervical metastases were performed.Bone cement leakage was observed by X-ray and CT after operation,and complications were recorded during and after operation.Follow-up visits were made by outpatient or telephone until the 3rd month after the operation.By comparing visual analogue scale (VAS),analgesic use score,cervical dysfunction index (NDI) and KPS before and after operation,the improvement of the quality of life of patients after operation was comprehensively evaluated.The measurement data were expressed as (Mean ± SD).The paired t test was used to test the normal distribution of the paired difference before and after the operation,and the paired rank sum test was used to test the difference before and after the operation which did not conform to the normal distribution.Results The preoperative Tokuhashi correction score was (7.15 ± 2.87) score in 20 patients and the Tomita score was (7.55 ± 2.21) score.The single-segment cervical vertebrae cement injection volume was (1.17 ± 0.25) ml.The postoperative cement leakage rate was 53.13％ (17/32),but no serious complications.VAS before surgery and 3 months after surgery [preoperative (8.30 ± 1.08) score,postoperative (3.60 ± 1.67) score,P =0.000)],analgesic use score [preoperative (3.35 ± 0.59) score,postoperative (1.70 ± 0.80) score,P =0.000],cervical dysfunction index [preoperative (63.10 ± 7.94) score,postoperative (42.55 ± 15.69) score,P =0.000)] and KPS [Preoperative (54.50 ± 6.86) score,postoperative (61.67 ± 12.95) score,P =0.011] were significantly improved,and the difference was statistically significant.Conclusion PVP via anterolateral approach is effective in the treatment of advanced cervical metastases of lung cancer,and can effectively improve the quality of life of patients with advanced cervical metastases,but the surgical leakage rate is high and needs attention.
RESUMEN
Objective To understand the prevalence of HIV infection and its influencing factors in the premarital physical examination population in Dehong Prefecture, Yunnan Province, 2017. Methods The data of people receiving premarital medical examination was collected, the demographic characteristics was described and the related factors was analyzed by Logistic regression. Results There were 21 875 participants receiving premarital medical examination in Dehong. 98(0.45%) participants were confirmed positive for HIV and male infection rate was 0.47% (52/10 955) and female was 0.42% (46/10 920). Among the 98 patients, 20 patients were infected in the first time, and main route was sexual transmission accounting for 81.63% (80/98). Logistic multivariate regression analysis showed that age, ethnicity and drug use were the influencing factors for premarital couples infecting HIV. The risk of HIV infection in 31-40 and 41-50 years old group was higher than the people under 25 years old group(OR=3.78, 95% CI：1.81-7.89, P<0.001；OR=3.95, 95% CI：1.72-9.08, P=0.001). The infection risk of Dai and Jingpo ethnic group was higher than that of the Han ethnic(OR=1.86, 95% CI：1.06-3.29, P=0.031；OR=3.25, 95% CI：1.81-5.84, P<0.001). The risk of infection among drug users was much higher than non-drug users (OR=926.76, 95% CI：271.65-3 161.71, P<0.001). Conclusion Age, ethnicity, and drug use are influencing factors of HIV infection among premarital couples. Targeted measures need to be taken against risk factors. HIV infection is mainly transmitted by sexual transmission. It can be effectively detected and controlled through premarital medical examination.
