ABSTRACT

Objective To observe the effects of a 1 470 nm semiconductor laser on vaporization cutting, coagulation, and thermal injury of ex vivo animal tissues, aiming to explore the feasibility of its application in the treatment of benign prostatic hyperplasia.Methods The experimental group and control group were treated with HANS-D1 and ML-DD01FI 1 470 nm semiconductor laser therapy equipment, respectively. Fresh ex vivo pig bladder tissue was exposed to lasers with the optical fiber placed at distances of 0.5 cm and 1 cm from the tissue for 5 s. The effects of layers at powers of 60, 90, 120, 150, and 160 W on tissue injury were observed. Ex vivo dog prostate and pig kidney tissues were used for vaporization ablation and cutting to observe the effects of lasers at the same power levels on tissue vaporization and cutting thermal injury. Additionally, in coagulation mode, the effects of 30, 40, and 50 W semiconductor lasers on tissue coagulation were observed after irradiating ex vivo pig kidney tissue for 5, 10, and 15 seconds. Results When the optical fiber was placed 1 cm away from the tissue, the 1 470 nm semiconductor lasers did not cause accidental damage to adjacent normal bladder tissue. However, at a distance of 0.5 cm, the 120 W, 150 W, or 160 W lasers caused slight damage to the bladder tissue. In addition, with the increase in output power, the vaporization ablation efficiency of 60-160 W lasers on dog prostate tissue gradually increased, showing a good linear correlation between vaporization volume and total energy consumption (P<0.001). Histopathological HE staining results indicated that the coagulation layer thickness in the experimental group was 292.20-309.98 µm, and the vaporization layer depth was 1.49-4.52 mm. In the control group, the coagulation layer thickness was 289.91-303.53 µm, and the vaporization layer depth was 1.88-4.43 mm. There was no significant difference between the two groups (P>0.05). Moreover, when performing vaporization cutting on ex vivo pig kidney tissue with a cross-sectional area of 1 cm2, the efficiency of vaporization cutting by the 60-160 W 1 470 nm semiconductor lasers increased with the increase in output power (P<0.05). The coagulated layer thickness in the experimental group was 496.04-514.47 µm, while that in the control group was 489.39-518.53 µm. Additionally, in coagulation mode, when ex vivo pig kidney tissue was irradiated for 5, 10, and 15 s with 30, 40, and 50 W semiconductor lasers, the coagulation diameter, groove depth, and coagulation efficiency gradually increased with the increase in laser output power (P<0.05). The coagulation layer thickness in the experimental group and control group was 399.10-449.98 µm and 392.97-447.65 µm, respectively, and the vaporization layer depth was 3.05-7.09 mm and 2.70-7.14 mm, respectively. There was no significant difference between the two groups (P>0.05).Conclusion The 1 470 nm semiconductor laser shows good vaporization ablation, cutting, and coagulation effect on ex vivo tissues, with a good linear correlation between the effect and the output energy.

ABSTRACT

Objectives: To examine the influence of adjuvant chemotherapy after radical resection on the survival of patients with intrahepatic cholangiocarcinoma(ICC) and to identify patients who may benefit from it. Methods: The clinical and pathological data of 654 patients with ICC diagnosed by postoperative pathology from December 2011 to December 2017 at 13 hospitals in China were collected retrospectively. According to the inclusion and exclusion criteria,455 patients were included in this study,including 69 patients (15.2%) who received adjuvant chemotherapy and 386 patients (84.8%) who did not receive adjuvant chemotherapy. There were 278 males and 177 females,with age of 59 (16) years (M(IQR))(range:23 to 88 years). Propensity score matching (PSM) method was used to balance the difference between adjuvant chemotherapy group and non-adjuvant chemotherapy group. Kaplan-Meier method was used to plot the survival curve,the Log-rank test was used to compare the difference of overall survival(OS) and recurrence free survival(RFS)between the two groups. Univariate analysis was used to determine prognostic factors for OS. Multivariate Cox proportional hazards models were then performed for prognostic factors with P<0.10 to identify potential independent risk factors. The study population were stratified by included study variables and the AJCC staging system,and a subgroup analysis was performed using the Kaplan-Meier method to explore the potential benefit subgroup population of adjuvant chemotherapy. Results: After 1∶1 PSM matching,69 patients were obtained in each group. There was no significant difference in baseline data between the two groups (all P>0.05). After PSM,Cox multivariate analysis showed that lymph node metastasis (HR=3.06,95%CI:1.52 to 6.16,P=0.039),width of resection margin (HR=0.56,95%CI:0.32 to 0.99,P=0.044) and adjuvant chemotherapy (HR=0.51,95%CI:0.29 to 0.91,P=0.022) were independent prognostic factors for OS. Kaplan-Meier analysis showed that the median OS time of adjuvant chemotherapy group was significantly longer than that of non-adjuvant chemotherapy group (P<0.05). There was no significant difference in RFS time between the adjuvant chemotherapy group and the non-adjuvant chemotherapy group (P>0.05). Subgroup analysis showed that,the OS of female patients,without HBV infection,carcinoembryonic antigen<9.6 μg/L,CA19-9≥200 U/ml,intraoperative bleeding<400 ml,tumor diameter>5 cm,microvascular invasion negative,without lymph node metastasis,and AJCC stage Ⅲ patients could benefit from adjuvant chemotherapy (all P<0.05). Conclusion: Adjuvant chemotherapy can prolong the OS of patients with ICC after radical resection,and patients with tumor diameter>5 cm,without lymph node metastasis,AJCC stage Ⅲ,and microvascular invasion negative are more likely to benefit from adjuvant chemotherapy.

ABSTRACT

Objective:To compare the medium-term clinical effects of arthroscopic double row repair between traumatic and degenerative medium supraspinatus tear.Methods:A retrospective study was conducted to analyze the clinical data of 23 patients who had been treated for traumatic or degenerative medium supraspinatus tear by the same arthroscopic double row repair and postoperative rehabilitation at Sports Medicine Center, The First Hospital Affiliated to Army Medical University between January 2015 and August 2020. They were assigned into 2 groups according to different tears. In the traumatic group of 8 cases of traumatic medium supraspinatus tear, there were 5 males and 3 females with an age of (46.1±4.3) years and a tear size of (1.3±1.0) cm 2. In the degenerative group of 15 cases of degenerative medium supraspinatus tear, there were 4 males and 11 females with an age of (59.9±8.1) years and a tear size of (4.1±1.1) cm 2. At preoperation and the last follow-up, the shoulder pain was evaluated by visual analogue scale (VAS), and the shoulder function by American Shoulder and Elbow Surgeons (ASES) score, Constant-Murley score and Simple Shoulder Test (SST); the improvements in active range of motion (ROM) of the shoulder were recorded at the last follow-up. Results:The 2 groups were comparable because there was no significant difference between them in the general clinical data ( P>0.05). The traumatic and degenerative groups were followed up for (40.3±11.2) and (36.4±12.4) months, respectively. At the last follow-up, the improvements in range of anterior flexion and internal rotation vertebral rank in the degenerative group [55.3°±33.6° and (4.1±1.3) ranks] were significantly greater than those in the traumatic group [27.5°±22.5° and (2.3±1.9) ranks] ( P<0.05). At the last follow-up, the VAS, ASES, Constant-Murley, and SST scores in the degenerative group were improved respectively by (3.7±0.8), (40.9±14.0), (38.4±9.4), and (6.5±1.4) points compared with their preoperative values, significantly greater than those in the traumatic group [(2.3±0.7), (19.6±14.6), (19.2±7.9), and (3.8±0.7) points] ( P<0.05). Conclusion:Arthroscopic double row repair can achieve significant medium-term improvements in shoulder function for both traumatic and degenerative medium supraspinatus tears, but the improvements may be grater for the degenerative ones.

ABSTRACT

Aging is a crucial factor influencing postural stability control and contributing to frequent falls, yet its underlying mechanisms remain incompletely understood. This study aims to explore the effects of aging on postural stability control by comparing differences in postural stability and node strength of electroencephalogram (EEG) brain network between elderly and young people under the conditions of congruent and incongruent visual-vestibular sensory inputs. Eighteen elderly volunteers without neuromuscular disorders and eighteen young individuals participated in the present study. Virtual reality (VR) technology was employed to manipulate visual rotation stimuli (clockwise and counterclockwise), and a horizontal rotating platform was used for vestibular rotation stimuli (clockwise). Based on the directional disparity of sensory input in the horizontal plane, visual-vestibular input consistency was categorized as congruent and incongruent. Postural stability was assessed by the center of pressure (COP) trajectory, and EEG signals were collected and analyzed using directed network analysis to observe EEG brain network node connectivity strength. The results revealed that, under conditions of incongruent visual-vestibular sensory inputs, the elderly exhibited significantly inferior postural stability performance in terms of COP anterior-posterior (Y-axial) sway speed, total path length, anterior-posterior and medial-lateral sample entropy, compared to the young adults. Moreover, the node connectivity strength of visual cortex in the elderly was notably higher, while node connectivity strength of superior temporal cortex was significantly lower than that in the young adults. These findings suggest that the elderly have a heightened reliance on visual information in postural control and an impaired ability to cope with sensory conflicts arising from incongruent visual-vestibular sensory inputs, leading to compromised postural stability. The outcomes of this study hold significant implications for future assessments of balance function in the elder and fall prevention trainings.

ABSTRACT

Objective:To evaluate the clinical efficacy of biplane osteotomy in the treatment of malunion of Stephens-Sanders type Ⅱ calcaneal fracture.Methods:A retrospective study was conducted to analyze the clinical data of 31 patients who had been treated by biplane osteotomy at Sports Medicine Center, The First Affiliated Hospital of Army Medical University for malunion of Stephens-Sanders type Ⅱ calcaneal fracture from January 2019 to January 2022. There were 21 males and 10 females, with an age of (41.4±13.9) years and a duration from injury to diagnosis of (12.8±8.9) months. Functional and image scores were compared before surgery, 6 months after surgery, and at the last follow-up. Functional scores included the visual analogue scale (VAS) score, the American Orthopedic Foot and Ankle Society (AOFAS) score, and the pain interference (PI) and physical function (PF) indices in the Patient-Reported Outcomes Measurement Information System (PROMIS). Image scores included the Gissane angle, B?hler's angle, calcaneal pitch angle, length of the calcaneus, absolute foot height, and axial calcaneal width as measured on X-rays.Results:The operation time was (106.6±29.9) minutes for this cohort. All the 31 patients were followed up for (18.4±5.8) months. At 6 months after surgery and the last follow-up, the VAS scores [3 (2, 3), 2 (1, 3)], AOFAS scores [83 (76, 87), 85 (83, 87)], PI scores [(57±9), (48±6)], PF scores [53 (39, 61), 56 (54, 66)], Gissane angles (109.6°±14.1°, 109.3°±14.9°), B?hler angles (26.5°±11.6°, 26.9°±11.8°), calcaneal pitch angles [19.1° (14.5°, 23.9°), 19.9° (14.5°, 23.9°)], absolute foot heights [(76.5±9.6) mm, (76.0±9.9) mm], and axial calcaneal widths [(38.5±4.1) mm, (38.3±4.1) mm] were all significantly improved compared to the preoperative values [5 (4, 6), 62 (56, 67), (62±6), 47 (38, 51), 126.8°±13.1°, 11.8°±10.9°, 13.8° (8.2°, 18.7°), (71.0±9.1) mm, (42.8±5.5) mm] (all P<0.05). However, there was no statistically significant difference in the length of the calcaneus among pre-surgery, 6 months after surgery, and the last follow-up ( P>0.05). Conclusion:Biplane osteotomy is a surgical technique that demonstrates good clinical efficacy in the treatment of malunion of Stephens-Sanders type Ⅱ calcaneal fracture so that it should be promoted in clinic.

ABSTRACT

Da Jianzhongtang, which is from Synopsis of Golden Chamber(《金匮要略》), is one of the hundred ancient classical formulas. In this textual research, a total of 46 records on this prescription from 42 ancient books and 207 records from modern literature were screened out. Through systematic research on its name, dosage, processing, evolution of the meaning on prescription compatibility, indications, decocting methods, usage, and precautions, this paper aims to lay a literature basis for further research on Da Jianzhongtang. The results show that the converted dosages for the components are 3 g of Zanthoxyli Pericarpium, 12 g of Zingiberis Rhizoma, 6 g of Ginseng Radix et Rhizoma, and 30 g of Saccharum Granorum. The efficacy can be labeled on the prescription instruction as warming the middle and tonifying deficiency, descending adverse Qi and relieving pain. According to modern literature, the main indications include diseases in digestive system, circulatory system, orthopedic system, urinary system, and ophthalmic system, particularly the intestinal obstruction, gastric ulcer, chronic gastritis, and duodenal ulcer in the digestive system. The core pathogenesis of the above diseases is "deficiency-cold of middle energizer and internal exuberant cold". Precautions are as follows. ① For the processing of Zanthoxyli Pericarpium, stir-frying can alleviate its toxicity and increase the decoction rate of effective ingredients. ② For the dosage, overdosage will lead to dry cough, edema, etc. ③ As to the contraindications after the medication, raw, cold, or indigestible food should not be taken after medication. ④ For the syndrome taboos, this prescription should be used with caution for patents with Yin deficiency, congealing cold, and Qi stagnation, and be forbidden for patients with spleen and stomach dampness-heat. The above results lay a basis for the research and development of the compound preparation for Da Janzhongtang and provide a reference for its instructions.

ABSTRACT

ObjectiveTo observe the clinical efficacy of modified Tuoli Xiaodusan (TLXDS) in adjuvant treatment of Helicobacter pylori (Hp)-positive peptic ulcer (PU) with cold-heat complex syndrome and explore its regulating effect on invasive/protective factors. MethodA total of 136 patients were randomly assigned into the control group (68 cases, including 4 cases missing, 3 cases eliminated, and 61 cases completed) and the TLXDS group (68 cases, including 4 cases missing, 1 case eliminated, and 63 cases completed). Both groups adopted the quadruple therapy of acid suppression and Hp eradication. The patients in the control group received Weinai'an capsules orally at 4 capsules/time and 3 times/day, and those in the TLXDS group took modified TLXDS orally at 1 dose/day. The administration of both groups lasted for 8 consecutive weeks and the follow-up lasted for 12 months. Electronic gastroscopy was carried out before and after treatment for evaluating the healing of ulcer, the score of mucosal morphology, and the maturity of regenerated mucosa. The Hp infection and the score of cold-heat complex syndrome were evaluated before and after treatment. The serum levels of gastrin (GAS), prostaglandin E2 (PGE2), pepsinogen (PG)-Ⅰ, PG-Ⅱ, epidermal growth factor (EGF), and trefoil factor 2 (TFF-2) were determined before and after therapy. The recurrence of Hp and PU was recorded, and the drug safety was evaluated. ResultAfter treatment, the mucosal morphology score and the traditional Chinese medicine (TCM) syndrome score in the TLXDS group were lower than those in the control group (P<0.01). The levels of GAS, PG-Ⅰ, and PG-Ⅱ in the TLXDS group were lower than those in the control group (P<0.01), whereas those of PGE2, EGF, and TFF-2 showed an opposite trend (P<0.01). After treatment, the Hp eradication rate in the TLXDS group was 95.24% (60/63), higher than that (83.61%, 51/61) in the control group (χ2=4.467, P<0.05). The total effective rate of TCM syndromes in the TLXDS group was 98.41% (62/63), higher than that (81.97%, 50/61) in the control group (χ2=9.589, P<0.01). The total effective rate of the TLXDS group under gastroscopy was 98.41% (62/63), higher than that (86.89%, 53/61) in the control group (χ2=4.525, P<0.05). The excellent and good rate of regenerated mucosal maturity in the TLXDS group was 92.06% (58/63), also higher than that (73.77%, 45/61) in the control group (χ2=7.372, P<0.01). After 12 months of follow-up, the TLXDS group had lower PU recurrence rate [19.05% (12/63) vs 37.70% (23/61), χ2=5.325, P<0.05] and lower Hp recurrence rate [15.00% (9/60) vs 33.33% (17/51), χ2=5.165, P<0.05) than the control group. No adverse reactions related to TLXDS were detected. ConclusionModified TLXDS-assisted quadruple therapy demonstrates significant short-term clinical efficacy and high Hp eradication rate for Hp-positive PU (cold-heat complex syndrome) patients. Moreover, it can adjust the levels of invasive/protective factors to facilitate ulcer healing and reduce the recurrence rates of Hp and PU in a long term, with good clinical safety.

ABSTRACT

OBJECTIVE@#To evaluate the efficacy of long reconstruction plate combined with minimally invasive percutaneous plate osteosynthesis(MIPPO) technique in the treatment of unstable pelvic anterior ring fractures.@*METHODS@#From January 2013 to February 2019, 16 patients with unstable pelvic fracture were treated, including 12 males and 4 females, aged from 20 to 60 years(mean 46.5 years). According to Tile classification, there were 4 cases of type B1, 6 cases of type B2, 4 cases of type C1 and 2 cases of type C2. The fracture of all patients was closed, and the time from injury to operation was 7 to 10 days with an average of 6.2 days. The operation time, intraoperative blood loss, fracture reduction quality, fracture healing time, complications and limb function during the final follow-up were evaluated in 16 patients.@*RESULTS@#All 16 patients were followed up for 12 to 23 months (mean 19.1 months). The operation time was 60 to 180 min (mean 107.8 min). The intraoperative blood loss was 120 to 600 ml (mean 368.1 ml). The fracture healing time was 12 to 20 weeks (mean 16.3 weeks). According to Matta criteria, the fracture reduction was excellent in 6 cases, good in 8 cases and fair in 2 cases. One patient suffered from lateral femoral cutaneous nerve injury during the operation, and the lateral thigh sensation decreased after operation, which recovered after 6 months. One patient had pain stimulated by internal fixation at the iliac fossa. The symptoms were improved after the internal fixation was removed. The fractures of 16 patients were healed satisfactorily and there was no internal fixation loosening. Majeed score at the final follow-up was 67 to 95, excellent in 10 cases, good in 4 cases and fair in 2 cases.@*CONCLUSION@#Closed reduction and fixation of pelvic anterior ring fracture with long reconstruction plate combined with MIPPO technique through anterior approach has the advantages of less injury, less bleeding time during operation, saving operation time, high intraoperative safety, high fracture healing rate, early functional exercise after operation, and effective treatment of pelvic anterior ring fracture.

ABSTRACT

ARIDI A encodes a non-catalytic subunit of SWI/SNF chromosome remodeling complex BAF. Cancer genome sequencing data based on next-generation sequencing techniques have shown that ARIDIA is frequently mutated in a variety of cancers, up to 20% in some cancer types. A growing body of evidence shows that ARIDIA, as a tumor suppressor gene, affects the occurrence and development of cancers. ARIDIA plays an important role in cell cycle, DNA replication, DNA repair and transcriptional regulation, which might contribute to tumor formation, proliferation and migration. This review article mainly describes the research progress on ARIDIA in pan-cancer, as well as potential therapeutics, hoping to provide new ideas for the diagnosis and treatment of tumors.

ABSTRACT

OBJECTIVE@#To explore the influencing factors of perioperative blood transfusion in the treatment of elderly femoral intertrochanteric fractures with proximal femoral nail antirotation(PFNA).@*METHODS@#The clinical data of 109 elderly patients with intertrochanteric fractures who received PFNA treatment from July 2018 to January 2020 were retrospectively analyzed. Both pelvic hip X-rays and CT plain scans were performed before surgery. All patients were diagnosed by X-ray and CT plain scan of pelvis and hip before operation. Through the statistical analysis of the basic data of patients before and during operation, the risk factors of perioperative blood transfusion were explored.@*RESULTS@#Logistic regression analysis showed that age (@*CONCLUSION@#Age, fracture type, diabetes history, and preoperative hemoglobin are independent risk factors for perioperative blood transfusion in the treatment of elderly intertrochanteric fractures with PFNA. The older the patient, the history of diabetes, the more unstable the fracture, and the lower preoperative hemoglobin, the more likely it is to require a blood transfusion, which may provide a reference for clinical perioperative blood transfusion decisions.

ABSTRACT

BACKGROUND@#Single-nucleotide polymorphisms (SNPs)-associated genes and long non-coding RNAs (lncRNAs) can contribute to human disease. To comprehensively investigate the contribution of lncRNAs to breast cancer, we performed the first genome-wide lncRNA association study on Han Chinese women.@*METHODS@#We designed an lncRNA array containing >800,000 SNPs, which was incorporated into a 96-array plate by Affymetrix (CapitalBio Technology, China). Subsequently, we performed a two-stage genome-wide lncRNA association study on Han Chinese women covering 11,942 individuals (5634 breast cancer patients and 6308 healthy controls). Additionally, in vitro gain or loss of function strategies were performed to clarify the function of a novel SNP-associated gene.@*RESULTS@#We identified a novel breast cancer-associated susceptibility SNP, rs11066150 (Pmeta = 2.34 × 10-8), and a previously reported SNP, rs9397435 (Pmeta = 4.32 × 10-38), in Han Chinese women. rs11066150 is located in NONHSAT164009.1 (lncHSAT164), which is highly expressed in breast cancer tissues and cell lines. lncHSAT164 overexpression promoted colony formation, whereas lncHSAT164 knockdown promoted cell apoptosis and reduced colony formation by regulating the cell cycle.@*CONCLUSIONS@#Based on our lncRNA array, we identified a novel breast cancer-associated lncRNA and found that lncHSAT164 may contribute to breast cancer by regulating the cell cycle. These findings suggest a potential therapeutic target in breast cancer.

ABSTRACT

OBJECTIVE To observe the protective effect of sesamin (Ses) and vitamin E (Vit E) against aortic endothelial dysfunction in rats induced by D-galactose (D-gal) and aluminum trichloride (AlCl3), and explore its conceivable mechanisms. METHODS A model of aortic endothelial dysfunction rats was established by D-gal (180 mg · kg-1, ip) combined with AlCl3 (15 mg · kg-1, ig) for 84 d. Model rats were randomly divided into model, model+Vit E 10 mg·kg-1, model+Ses 160 mg·kg-1, and model+Ses 160 mg · kg-1+Vit E 10 mg · kg-1 groups. After 70 d of treatment with Ses and Vit E, systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean blood pressure (MBP) were measured by tail cuff. The rats were anesthetized by sodium pentobarbital (30 mg·kg-1, ip). Thoracic aortas from the rats were removed and divided into two parts (3 mm in length). The relaxation of the aortic ring induced by acetylcholine (ACh) and sodium nitroprusside was measured. The primary pathologic changes in the aorta were observed by HE staining. Total antioxidant capacity (T-AOC), hydrogen peroxide (H2O2) and nitric oxide (NO) in serum were measured by colorimetric analysis. The expression of endothelial nitric oxide synthase (eNOS) positive cells in the aorta were measured by immunohistochemistry. The expres?sions of eNOS and NAD(P)H oxidase 4 (NOX4) protein in the aortal were detected by Western blotting. RESULTS Compared with the model group, the relaxation response with increase in ACh concentra?tion (1×10-7-1×10-4 mol·L-1) was enhanced (P<0.01) in model+Ses+Vit E, SBP, DBP and MBP decreased (P<0.01), the serum T-AOC and NO level were increased (P<0.01), the serum H2O2 levels were reduced (P<0.01), the eNOS expression was increased (P<0.01) and NOX4 expression was reduced (P<0.01) in each treatment group. Compared with model+Ses, the SBP, DBP and MBP were lower (P<0.01 or P<0.05), the serum H2O2 level was lower (P<0.01), the serum NO level was increased (P<0.05), the eNOS expression level was higher (P<0.01) and the NOX4 expression level was reduced (P<0.05) in model+Ses+Vit E. Compared with the model+Vit E, the serum T-AOC and NO levels were increased (P<0.05), the serum H2O2 level was lower (P<0.01), eNOS expression was increased (P<0.01) and NOX4 expression was reduced (P<0.05) in model+Ses+Vit E group. CONCLUSION Ses and Vit E can ameliorate aortic endothelial dysfunction of rats induced by D-gal and AlCl3 via the regulation of eNOS and NOX4.

ABSTRACT

OBJECTIVE@#To investigate the oral cancer awareness, its related knowledge among residents in Beijing.@*METHODS@#A questionnaire survey was conducted among Beijing residents (non-medical related personnel) on the knowledge of oral cancer and its prevention and treatment.@*RESULTS@#A total of 1 483 questionnaires were completed, including 663 males (44.6%) and 820 females (55.3%), ranging from 15 to 91 years. Lung cancer was the most mentioned as heard of (94.3%), followed by liver cancer (92.5%) and gastric cancer (92.4%), while oral cancer was the least heard of (47.7%). Family account (P=0.015), residence (P=0.028), income (P=0.024), frequency of brushing teeth (P<0.001), frequency of mouth self-examination (P<0.001) and chew betel nut chewing (P=0.015) were significantly associated with oral cancer awareness. Most respondents learned about oral cancer from TV programs (24.3%), phone news (22.0%), WeChat (11.3%) and chatting with friends or people around (14.6%). Only 34.9% knew that smoking was a risk factor of oral cancer, and this knowledge was associated with age (P=0.011), education level (P=0.007), frequency of brushing teeth (P<0.001), and frequency of mouth self-examination (P=0.002). Only 23.5% knew that drinking was a risk factor of oral cancer, and this knowledge was associated with education level (P=0.002), residence (P=0.022), frequency of brushing teeth (P=0.009), and frequency of mouth self-examination (P=0.005). Only 35.1% knew that betel nut chewing was a risk factor for oral cancer, and this knowledge was associated with age (P=0.040), education level (P=0.002), family account (P=0.002), income (P=0.005), frequency of brushing teeth (P=0.001), frequency of mouth self-examination (P<0.001), and betel nut chewing (P=0.002). Only 35.7%, 21.6% and 16.9%, respectively, knew that long-term unhealed ulcers, white plaques and red plaques in the mouth were the early signs of oral cancer.@*CONCLUSION@#This survey demonstrates a general lack of public awareness and knowledge about signs and symptoms of oral cancer, and its risk factors and treatment. Some residents have not formed good oral hygiene habits. Specific measures should be taken to improve the public awareness of oral cancer and related knowledge about prevention and treatment, such as the use of various new media for the public to promote their oral health knowledge, in order to reduce the incidence of oral cancer, improve early attendance rates and the patients' survival rates.

ABSTRACT

OBJECTIVE@#To systematically evaluate the clinical efficacy of high-quality direct anterior approach (DAA) and other approaches for the treatment of elderly patients with femoral neck fracture.@*METHODS@#Literatures published in English or Chinese about the direct anterior approach and other approaches for hemiarthroplasty in femoral neck fracture were searched on Cochrane Library, PubMed, EMBASE, Web of science, Wanfang, CNKI databases from their establishment to May 2019. According to the inclusion and exclusion criteria, two researchers independently screened the literatures, and extracted the data. The quality of RCT were evaluated by Cochrane Risk of Bias Assessment Tool, and non-RCT were evaluated by the NOS scale. Meta-analysis was performed using the RevMan 5.3 software.@*RESULTS@#A total of 9 articles were included with 901 cases, in which 429 cases used DAA, and 472 used other approaches. DAA had a significantly lower dislocation rate compared to subgroup of posterior and posterolateral approach [=0.19, 95%CI (0.06, 0.61), =0.005]. No significant differences were found between DAA group and subgroup of direct lateral and anterolateral approach[=1.08, 95%CI(0.20, 5.76), =0.93]. Also there were no relevant differences between the DAA group and control in infection rate[=1.07, 95%CI(0.47, 2.43), =0.88], perioperative fracture rate[=0.95, 95%CI(0.36, 2.50), =0.92], re operation rate[=0.76, 95%CI(0.30, 1.89), =0.55], overall complication rate [=0.88, 95%CI (0.63, 1.22), =0.44], mortality [=1.33, 95%CI (0.84, 2.11), =0.23], operative time[MD=1.43, 95%CI(-5.85, 8.71), =0.70].@*CONCLUSION@#The current evidenceindicates that the DAA was associated with a significantly lower dislocation rate compared to posterior capsular approaches for hemiarthroplasty. There was no significant difference in dislocation rate with the lateral and anterolateral approach.
