ABSTRACT

PURPOSE@#The rapid development of winter sports requires investigation on injuries in Chongli district, Zhangjiakou city, one of the ski sites of the 2022 Winter Olympics. Careful evaluation is required to observe which injuries are caused under what circumstances, and then we can make corresponding preventive measures and recommendations based on the results.@*METHODS@#In this retrospective study, the data of injury cases at ski resorts in China (Chongli district) and Japan were analyzed to provide a reference for the ongoing injury prevention at ski resorts. We collected data on injuries at Wanlong and Fulong ski resorts in Chongli district during the 2017-2018 and 2018-2019 ski seasons. We referred to the skiing injury report issued in February 2020 of a nationwide ski safety statistical service - Japan Ski Safety Association. The causes of injury and specific injured body parts were analyzed based on the data of Chinese and Japanese ski resorts. Statistical significance has been calculated using the Chi-square test.@*RESULTS@#During the 2019-2020 ski season in Japanese ski resorts, the number of reported injuries per 10,000 skiers was 0.93, of which 457 (17.3%) were over 50 years old, accounting for a large proportion of injuries, meanwhile in Chongli ski resort, the injury rate of skiers aged 50 and over was 7.1%. The knee joint (23.7% at Wanlong ski resort and 28.4% in Japanese ski resorts) was the most injured body part among Chongli and Japanese skiers. Among snowboarders, shoulder joint injury (17.7% in Japanese ski resorts) was the most common, and injury on hands and fingers (16.3% in Wanlong ski resorts) was the most common. Head injury rates are similar in Chongli, China and Japanese ski resorts (8.2% and 8.7%, respectively).@*CONCLUSION@#Our analysis demonstrated that injury data recorded among young skiers was higher in Chinese ski resorts (Chongli district) than that in Japanese ski resorts, and elderly skiers made up a larger proportion of skiing injuries in Japanese resorts. Thus, according to our research, the protection of knee joints, shoulder joints, and hands and fingers should be taken seriously. It should pay attention to the teaching of ski poles (for finger protection), and use protective devices such as knee pads, helmets, etc.

ABSTRACT

Objective: To analyze the characteristics of allergen spectrum in patients with allergic rhinitis (AR) in Xinjiang area in recent 13 years. Methods: The skin prick test (SPT) results of 5 019 AR patients from 2007 to 2019 were retrospectively summarized, and 14 allergens of different age, gender and race were analyzed. Results: The distribution of 14 allergens was significantly different in different years, the difference was significant (P<0.05). The top three positive rates of 14 allergens were quinoa 48.2% (2 398/4 970), plantain 33.3% (1 221/3 667), and Artemisia 33.1% (1 647/4 974). There was no significant difference in the positive rate of dog epithelium between different genders and ages (χ²=0.041, P>0.05; χ²=3.8, P>0.05), the difference of other allergen in positive rates was statistically significant (all P<0.05). The positive rates of Alternaria Alternata (χ²=7.3), Penicillium Sp. (χ²=0.3), Cat Epithelium (χ²=3.1), Dust Mite (χ²=1.4), Acaroid Mite (χ²=0.5) and Cockroach (χ²=2.9) had no significant difference among different races (all P>0.05). The positive rates of other eight allergens including Artemisia Vulgaris (χ²=64.9), Chenopodium (χ²=204.1), Artemisiifolia (χ²=72.4), Plantain (χ²=87.8), Phleum Pratense L(χ²=55.4), Robinia Pseudoacacia (χ²=67.8), Canis Familiari (χ²=70.8), Dog Epithelium (χ²=15.7) were significantly different among different races (all P<0.05). Conclusion: The distribution of allergens in Xinjiang area changes with time, the main allergens are mainly herbaceous, and the distribution of allergens in patients with AR is different in gender, age and race.

ABSTRACT

PURPOSE@#To retrospectively analyze the clinical outcomes of meniscus repair with simultaneous anterior cruciate ligament (ACL) reconstruction and explore the causes of failure of meniscus repair.@*METHODS@#From May 2013 to July 2018, the clinical data of 165 patients who were treated with meniscus surgery and simultaneous ACL reconstruction, including 69 cases of meniscus repair (repair group) and 96 cases of partial meniscectomy (partial meniscectomy group) were retrospectively analyzed. The exclusion criteria were as follows: (1) ACL rupture associated with fracture, collateral ligament injury, or complex ligament injury; (2) a history of knee surgery; or (3) a significant degree of osteoarthritis. The 69 patients in the repair group were divided into the non-failure group (62 cases) and the failure group (7 cases) depending on the repair effect. Postoperative outcomes of the repair group and the partial meniscectomy group were compared. General conditions and postoperative outcomes of the failure group and the non-failure group were compared. During the median follow-up period of 28 months (range, 4 - 65 months) after the second arthroscopy, postoperative outcomes of seven patients in the failure group were summarized. SPSS 25.0 statistical software was used for statistical analysis. A p value less than 0.05 was considered statistically significant.@*RESULTS@#Seven patients in the failure group who underwent the second arthroscopy were followed up for (30 ± 17.4) months and their postoperative outcomes were summarized. Compared with the partial meniscectomy group, the International Knee Documentation Committee scores of patients in the repair group improved significantly (p = 0.031). Compared with the non-failure group, more patients in the failure group were younger than 24 years (p = 0.030). The median follow-up period was 39.5 months. All patients recovered well after subsequent partial meniscectomy and relieved clinical symptoms. Visual analog scale scores decreased significantly (p = 0.026), and the International Knee Documentation Committee and Lysholm scores improved significantly (p = 0.046 for both).@*CONCLUSION@#The failure rate of meniscus repair in this study was 10.1% (7/69), all of which were medial meniscus tears. However, the surgical outcomes of ACL reconstruction were not affected, and there might be a role for graft protection. Therefore, meniscus retears can be successful treated by performing subsequent partial meniscectomy in patients with repair failure.

ABSTRACT

OBJECTIVE@#To compare and analyze the difference between the injuries of recreational skiers in public ski resorts and those of skiing athletes in official competitions, and to explore the suggestions of medical insurance for these two types of skiers.@*METHODS@#The injury data of recreational skiers in Chongli District, Zhangjiakou City, Hebei Province during 2018-2019 and 2019-2020 snow seasons, and the injury data of skiers in two official international skiing competitions during 2019-2020 snow season and domestic test events in Chongli District of 2021 Winter Olympic Games were analyzed retrospectively, and the similarities and differences were compared.@*RESULTS@#A total of 1 187 injuries occurred to recreational skiers in the two public ski resorts during the 2018-2019 snow season, with an injury rate of 0.3%.There were 1 277 injury sites in total, and the most frequent injury sites were head and neck (230 cases, 18.0%), followed by knee joint (204 cases, 16.0%) and lower extremity (131 cases, 10.3%). Thirty-one skiers were injured in the two official international skiing competitions in the 2019-2020 and 2020-2021 snow season, and in the domestic test competitions in the 2021 Winter Olympic Games, and the injury rates were 11.5%, 17.2% and 12.0%, respectively. There were 37 injury sites in total, among which 11 (29.7%) were in the head and neck, followed by 6 (16.2%) in the knee joint and 5 (13.6%) in the chest, rib and abdomen.@*CONCLUSION@#In order to better guarantee the safety of skiers and timely provide corresponding medical help, safety facilities and technical guidance should be added to the snow resort for leisure skiing, and medical stations should be set up in the snow resort. As the formal ski racing for skiing athletes during the game has 30 to 80 times higher injury ratesthan recreational skiers, and compared with the recreational skiing, head and neck injury rate is higher, and the damage is much heavier, more complete first aid facilities and experienced medical workers are, needed so the field should be equipped with the circuit inside the quantities, track fixed outside the clinic, surrounding referral hospitals set up trauma centers to provide athletes with more timely medical care.

ABSTRACT

OBJECTIVE@#To make a retrospective analysis of the situation and process of treating skiers' injuries in the medical station of the Wanlong ski resort in Chongli and the nearest treatment hospital, and to provide a basis for the establishment and optimization of the treatment process between the medical station of the Winter Olympics ski resort and the nearest treatment hospital, and to gain experience for medical security of mass skiing.@*METHODS@#The data of all ski injuries in Chongli District were collected from the medical station of the Wanlong ski resort during the 2018-2019 snow season (November 2018 to April 2019) and the nearest treatment hospital during two periods (March 2019, and November 2019 to January 2020). The differences of injury causes, injury types, injury sites, and treatment effects of the injured skiers were analyzed.@*RESULTS@#A total of 755 cases of ski injuries were recorded in the medical station of Wanlong ski resort, the estimated incidence of injury was 2.02‰ per day. The nearest treatment hospital treated a total of 838 injured skiers from different ski resorts in Chongli District in the two periods. In the records of the ski resort medical station, the main causes of injury were technical defects and turnovers (53.6%). Knee joint injury rate was the highest (18.7%), followed by head and neck (12.9%) and lower limb (11.9%). The number of injuries on intermediate roads was the highest (40.0%), the greatest number of injuries (81.2%) occurred when the age of skiing was less than 5 years. In the records of the nearest treatment hospital, the injury types were fracture or fissure fracture, contusion and trauma, and muscle and soft tissue injury, accounting for 30.5%, 27.4%, and 21.2% respectively. 9.6% of the injured took the snow field ambulance to the hospital, and 50% of them suffered from fractures or fissure fractures.@*CONCLUSION@#The injury rate of skiing in the 2018-2019 snow season of the Wanlong ski resort in Chongli was higher than that reported by foreign literature. Severe trauma (including severe fractures and concussions) could occur and patients needed to be transferred to the nearest hospital for treatment. The ski resort medical station and the nearest treatment hospital should be strengthened with adequate medical staff and equipment, and promote cooperation in the timely referral of seriously injured patients, the organization and construction of ski patrols and the medical security of large-scale competitions, thus playing an important role in forming a grassroots network of medical security and treatment system for skiing.

ABSTRACT

OBJECTIVE@#To make a retrospective analysis of the injuries of skiing population in a large ski resort in Chongli, China and provide a basis for predicting the rapidly increasing medical needs for ski injuries in the context of the 2022 Winter Olympic Games.@*METHODS@#The basic data of all injured skiers who were treated in a medical station of a large ski resort in Chongli during the snow season from November 2017 to March 2018 and from November 2018 to March 2019 were collected. The number of skiers, the number of injuries, the causes of injuries, the types of injuries and the locations of injuries were compared.@*RESULTS@#A total of 753 skiers were injured in two snow seasons, and the estimated average incidence of injury was 4.53 and 4.46 per 1 000 skier days at the resort respectively. The average daily injury rate per 1 000 skiers in November of the two snow seasons was relatively low, with 2.20 and 1.38 cases respectively. The difference of injury rate in different months might have little to do with snowfall and more to do with passenger flow. In both the snow seasons, men accounted for more injuries than women, and injured skiers aged between 21 and 30 accounted for the largest proportion, reaching 36.8%. The main causes of injuries were falls (76.6%). The highest rate of injury was in the head and neck (17.9%), followed by the knee (17.4%) and wrist and fingers (13.3%). The most common types of injuries were contusion and trauma (29.5%) and joint and/or ligament injuries (22.2%). Children (2-12 years old) accounted for 12.7% of all the injured skiers. The rate of moderate to severe injuries (including fractures, concussions, etc.) was 34.8% among the injured patients over 50 years of age.@*CONCLUSION@#The snow resort should focus on injuries to children and elderly skiers and carry out targeted guidance and rescue work. In order to better ensure the medical safety of skiers, the ski resort medical station and nearby treatment hospitals should be equipped with a corresponding number of medical personnel and equipment, and the ski resort should further improve its safety management and rescue system.

ABSTRACT

PURPOSE@#To evaluate the clinical outcome in patients who received anterior cruciate ligament (ACL) reconstruction via anteromedial portal with or without posterior wall blowout.@*METHODS@#Twenty patients with ruptured ACL, who have received ACL reconstruction via anteromedial portal between Apr 2012 and Oct 2013 were enrolled. According to the conditions of posterior wall, the patients were divided into 2 groups: posterior wall blowout group (10 patients) and posterior wall intact group (10 patients). The median follow up time were 63 (range 19-75) months and 60.5 (range 25-64) months in the 2 groups respectively. The clinical outcome was evaluated by knee joint physical examination, magnetic resonance imaging (MRI), the International Knee Documentation Committee (IKDC) 2000 subjective score, Lysholm score, Tenger score, difference of thigh circumference, KT-2000 and Biodex isokinetic dynamometer system.@*RESULTS@#No significant differences were found in terms of the IKDC score, Lysholm score, Tegner score, Lachman test positive rate or Pivot Shift test positive rate between the two groups. In KT-2000 and Biodex isokinetic dynamometer tests, the difference of muscle strength between affected knees and unaffected knees in posterior wall blowout group was not significant less than that of posterior wall intact group (p > 0.05). In addition, there is no statistical difference between the two groups in signal/noise quotient (SNQ) of the graft (p > 0.05) in post operative MRI.@*CONCLUSION@#Blowout of posterior wall in ACL reconstruction via anteromedial portal does not affect the clinical outcome as long as reliable fixation is taken intraoperatively.

ABSTRACT

Objective To observe the clinical efficacy of herb-partitioned moxibustion (HPM) at umbilicus in treating chronic prostatitis due to kidney-qi insufficiency. Method Sixty patients with chronic prostatitis due to kidney-qi insufficiency were randomized into a treatment group and a control group, 30 cases each. The treatment group was intervened by HPM, and the control group was treated with oral medication. The two groups were evaluated by using the National Health Institute-Chronic Prostatitis Symptom Index (NIH-CPSI) and the count of white blood cell of expressed prostatic secretion (EPS-WBC) before and after the intervention, and the clinical efficacies of the two groups were compared. Result The total effective rate was 90.0% in the treatment group versus 75.9% in the control group, and the between-group difference was statistically significant (P<0.05). The NIH-CPSI component scores were significantly changed in both groups after the treatment (P<0.01). There were no significant differences in the component scores of NIH-CPSI between the two groups after the treatment (P>0.05). The EPS-WBC count changed significantly in both groups after the treatment (P<0.01). After the intervention, the EPS-WBC count in the treatment group was significantly different from that in the control group (P<0.05). Conclusion HPM at umbilicus is an effective method in treating chronic prostatitis due to kidney-qi insufficiency.

ABSTRACT

To investigate the effect and the mechanism of puerarin in attenuating PM2.5-induced human umbilical vein endothelial cells (EA.hy926) injury, the samples of fine particulate matter (PM2.5) were collected and made into suspension. Different concentrations of PM2.5 (0,20, 200, 400 mg•L⁻¹) were used to contaminate EA.hy926 cells for 24 h. The cells survival rate was detected by MTT assay; cells apoptosis of EA.hy926cells was detected by flow cytometry; the protein levels of p-ERK1/2, Bax and Bcl-2 were detected by Western blot; the contents of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), malonaldehyde (MDA), and the activities of superoxide dismutase (SOD) and lactic dehydrogenase (LDH) were measured by ELISA. Puerarin at different concentrations (10, 50, 100 μmol•L⁻¹) or a specific inhibitor of ERK1/2 pathway PD98059 (20 μmol•L-1) was added into the EA.hy926 cells to observe the intervention effect and mechanism of puerarin. Compared with the control group, PM2.5 reduced the cells survival rate, up-regulatedp-ERK1/2 protein level and Bax/Bcl-2 ratio in a dose dependent manner to promote apoptosis; increased the contents of TNF-α, IL-6 and MDA, the activity of LDH, but decreased SOD activity in the EA.hy926 cells (P<0.05). Compared with PM2.5 group, puerarin increased the cells survival rate, down-regulated p-ERK1/2 protein level and Bax/Bcl-2 ratio in a dose dependent manner to inhibit the apoptosis; decreased the contents of TNF-α, IL-6 and MDA, the activity of LDH, but increased SOD activity in the EA.hy926 cells (P<0.05). The results indicated that puerarin could attenuate PM2.5-induced EA.hy926 cells injury via the inhibition of ERK1/2 pathway.

ABSTRACT

<p><b>OBJECTIVE</b>To compare open and arthroscopic methods for treatment of recalcitrant lateral epicondylitis.</p><p><b>METHODS</b>A prospective trial of 26 patients (28 elbows) with recalcitrant lateral epicondylitis were treated between May 2006 and September 2008. The mean duration of conservative care was 23. 0 months (4 - 60 months). The mean follow-up was 17.4 months (4 - 32 months). The patients were randomized divided into two groups, 13 elbows with an open Nirschl procedure and 15 with an arthroscopic Nirschl procedure. All patients had pre- and post-operative assessment using VAS (visual analog scale) scores, Mayo 12 points elbow scores, time of return to work or sports, satisfaction, and so on.</p><p><b>RESULTS</b>There were no significant differences in VAS scores at rest and activities of daily living, time of return to work or sports and satisfaction between the two groups. But there was a statistically significant difference in VAS scores at work and sports and Mayo 12 points elbow scores between the two groups. 100% of the patients had excellent or good results in the open group and 93.3% in arthroscopic group. There were no severe complications in this series.</p><p><b>CONCLUSIONS</b>Both open and arthroscopic Nirschl procedures are valid and reliable treatments for patients with refractory lateral epicondylitis. The patients in the open group have a better function in the return-to work and sports postoperatively than the arthroscopic group.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the management principle of revision after anterior cruciate ligament (ACL) reconstruction and the factors contributing to its result.</p><p><b>METHODS</b>The data of 12 patients who received revision after ACL reconstructions from November 2001 to July 2006 were studied retrospectively. The indication of the operation, the management during the procedure and the clinical results were analyzed.</p><p><b>RESULTS</b>All the patients had pathological instability after primary ACL reconstructions. In this group, 2 cases received primary bone transplantation. The other 10 cases received primary ACL revision. Among them, 4 cases were reconstructed with STG obtained from the same lateral, 4 cases were obtained from the opposite lateral, 1 case was reconstructed with bone-patellar tendon-bone (B-PT-B) obtained from the same lateral, and 1 case was reconstructed with iliotibial tractus. One year later, the mean side-to-side difference of KT-2000 examination were 1.6 mm and 3.1 mm at 90 degrees and 30 degrees. The mean IKDC, Lysholm and Tegner scores were 72.8, 78.3 and 4.9.</p><p><b>CONCLUSIONS</b>The functional results and objective stability could be obtained through revision ACL reconstruction. However, outcomes are less favorable than those with primary reconstructions, which might be related to the factors including deficiency of previous surgery and impact of revision procedure.</p>
