ABSTRACT
Objective: To investigate the effects of preoperative quetiapine on postoperative delirium (POD) and sleep quality in elderly orthopedic patients. Methods: Prospectively, 111 elderly patients, American Society of Anesthesiologists (ASA) grade â ¡-â ¢, scheduled to undergo knee or hip surgery in the Affiliated Huangyan Hospital of Wenzhou Medical University under continuous spinal anesthesia from August 2021 to March 2023, were selected and randomly divided into two groups by random number table: control group (group C, 1 h preoperative placebo) and quetiapine group (group Q, 1 h preoperative quetiapine 12.5 mg). In group C, 54 cases were enrolled, including 25 males and 29 females, with an average age of (73.5±4.9) years. In group Q, 57 cases were enrolled, including 26 males and 31 females, with an average age of (74.8±5.0) years. The primary outcome measures were the incidence of POD evaluated by using confusion assessment method (CAM) at 24, 48, and 72 hours after surgery, and the secondary outcome measures included Pittsburgh sleep quality index (PSQI) scores at 24 and 48 hours after surgery and satisfaction of pain management within 24 hours after surgery. Results: The incidence of POD at 24, 48, and 72 h after surgery in group Q was 5.4% (3/57), 12.5% (7/57), 14.3% (8/57), respectively, while that in group C was 18.2% (10/54), 21.8% (12/54), 21.8% (12/54), respectively. The incidence of POD at 24 h after surgery in group Q was lower than that in group C (P=0.036). There was no significant difference in the incidence of POD at 48 and 72 h after surgery between two groups (all P>0.05). The PSQI score of patients in group Q at 24 and 48 h after surgery were (3.8±1.2) and (6.9±1.1) scores, respectively, which in group C were (10.5±2.8) and (7.3±1.3) scores, respectively. Compared with group C, the PSQI score of patients in group Q at 24 h after surgery was significantly higher (P<0.001), but there was no significant difference at 48 h after surgery (P=0.068). The satisfaction scores of pain management at 24 h after surgery in group Q was (91±7) scores, which was higher than that in group C of (81±6) scores (P<0.001). Conclusion: Oral intake of low-dose quetiapine 1 h preoperatively can reduce the incidence of POD, improve postoperative sleep quality and enhance postoperative satisfaction of pain management at 24 hours after surgery in elderly orthopedic patients undergoing knee or hip surgery.

Fast radio bursts (FRBs) are highly dispersed, millisecond-duration radio bursts1-3. Recent observations of a Galactic FRB4-8 suggest that at least some FRBs originate from magnetars, but the origin of cosmological FRBs is still not settled. Here we report the detection of 1,863 bursts in 82 h over 54 days from the repeating source FRB 20201124A (ref. 9). These observations show irregular short-time variation of the Faraday rotation measure (RM), which scrutinizes the density-weighted line-of-sight magnetic field strength, of individual bursts during the first 36 days, followed by a constant RM. We detected circular polarization in more than half of the burst sample, including one burst reaching a high fractional circular polarization of 75%. Oscillations in fractional linear and circular polarizations, as well as polarization angle as a function of wavelength, were detected. All of these features provide evidence for a complicated, dynamically evolving, magnetized immediate environment within about an astronomical unit (AU; Earth-Sun distance) of the source. Our optical observations of its Milky-Way-sized, metal-rich host galaxy10-12 show a barred spiral, with the FRB source residing in a low-stellar-density interarm region at an intermediate galactocentric distance. This environment is inconsistent with a young magnetar engine formed during an extreme explosion of a massive star that resulted in a long gamma-ray burst or superluminous supernova.
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.

The mutation rate of anaplastic lymphoma kinase (ALK) in patients with non-small cell lung cancer is 3% to 7%. Due to its low mutation rate and better long-term survival compared with epidermal growth factor receptor-positive non-small cell lung cancer patients, therefore, it's called "diamond mutation". At present, there are three generations of ALK tyrosine kinase inhibitor (TKI) drugs in the world. The first-generation ALK-TKI drug approved in China is crizotinib, and the second-generation drugs are alectinib, ceritinib and ensartinib. Among them, ensartinib is an ALK-TKI domestically developed, and its efficacy is similar to that of alectinib. The main adverse event is transient rash, and compliance to ensartinib is better from the perspective of long-term survival of patients. The manifestation of rash caused by ensartinib is different from that of other ALK-TKI drugs. In order to facilitate clinical application and provide patients with more treatment options, under the guidance of the Committee of Cancer Rehabilitation and Palliative Care of China Anti-Cancer Association, this article collects and summarizes the common adverse reactions of ensartinib. Based on the clinical practice, a clear adverse classification and specific treatment plan are formulated, in order to provide a corresponding reference for clinicians to make more comprehensive clinical decisions.

Objective: To verify Baveno VI criteria, Expanded-Baveno VI criteria, liver stiffness×spleen diameter-to-platelet ratio risk score (LSPS), and platelet count/spleen diameter ratio (PSR) in evaluating the severity value of esophageal varices (EV) in patients with non-cirrhotic portal hypertension (NCPH). Methods: 111 cases of NCPH and 204 cases of hepatitis B cirrhosis who met the diagnostic criteria were included in the study. NCPH included 70 cases of idiopathic non-cirrhotic portal hypertension (INCPH) and 41 cases of nontumoral portal vein thrombosis (PVT). According to the severity of EV on endoscopy, they were divided into the low-bleeding-risk group (no/mild EV) and the high-bleeding-risk group (moderate/severe EV). The diagnostic value of Baveno VI and Expanded-Baveno VI criteria was verified to evaluate the value of LSPS and PSR for EV bleeding risk severity in NCPH patients. The t-test or Mann-Whitney U test was used to compare the measurement data between groups. Comparisons between counting data groups were performed using either the χ2 test or the Fisher exact probability method. Results: Considering endoscopy was the gold standard for diagnosis, the missed diagnosis rates of low/high bleeding risk EVs in INCPH/PVT patients with Baveno VI and Expanded-Baveno VI criteria were 50.0%/30.0% and 53.8%/50.0%, respectively. There were no statistically significant differences in platelet count (PLT), spleen diameter, liver stiffness (LSM), LSPS, and PSR between low-bleeding-risk and high-bleeding-risk groups in INCPH patients, and the area under the receiver operating characteristic curve (AUC) of LSPS and PSR was 0.564 and 0.592, respectively (P=0.372 and 0.202, respectively). There were statistically significant differences in PLT, spleen diameter, LSPS, and PSR between the low and high-bleeding risk groups in PVT patients, and the AUCs of LSPS and PSR were 0.796 and 0.833 (P=0.003 and 0.001, respectively). In patients with hepatitis B cirrhosis, the Baveno VI and Expanded-Baveno VI criteria were used to verify the low bleeding risk EV, and the missed diagnosis rates were 0 and 5.4%, respectively. There were statistically significant differences in PLT, spleen diameter, LSM, LSPS and PSR between the low-bleeding-risk and high-bleeding-risk groups (P<0.001). LSPS and PSR AUC were 0.867 and 0.789, respectively (P<0.05). Conclusion: Baveno VI and Expanded-Baveno VI criteria have a high missed diagnosis rate for EVs with low bleeding risk in patients with INPCH and PVT, while LSPS and PSR have certain value in evaluating EV bleeding risk in PVT patients, which requires further clinical research.

Objective: This investigation aims to assess the impact of CSF3R mutations and the presence of measurable residual disease (MRD) on the prognosis of patients with CEBPA double mutations who have acute myeloid leukemia (AML) . Methods: The prognostic significance of these two factors was examined in the present study, which included 66 patients with complete genetic mutations and sequential MRD information. Results: Following the second course of chemotherapy, the MRD status and CSF3R mutations of these patients were linked to their long-term prognosis. CSF3R mutated patients showed inferior relapse-free survival (RFS) (5-year RFS: 15.2% vs 38.7% , P=0.006) and overall survival (OS) (5-year OS: 18.2% vs 60.6% , P=0.038) compared with those with wild-type CSF3R. After the second course of chemotherapy, patients with negative MRD had an RFS of 64 months and an OS of not reaching, which was significantly longer than that of patients with positive MRD (15 and 48 months, and the P value were 0.004 and 0.050, respectively) . CSF3R mutations (HR=0.317, 95% CI 0.129-0.779, P=0.012) , WT1 mutations (HR=0.304, 95% CI 0.115-0.804, P=0.016) , and NRAS mutations (HR=0.153, 95% CI 0.061-0.385, P<0.001) were all independently associated with a poor prognosis for RFS, and CSF3R mutations and positive MRD tended to be independently associated with a poor prognosis for OS, according to the results of a Cox proportional-hazards model analysis (P values were 0.071 and 0.088, respectively) . The patients were divided into three groups based on their CSF3R mutation status and MRD status following treatment: wide-type CSF3R and negative MRD, mutated CSF3R or positive MRD, and mutated CSF3R and positive MRD, which showed significantly different RFS (P<0.001) and OS (P=0.006) . Conclusion: Both CSF3R mutations and positive MRD were associated with poor outcome in AML patients with CEBPA double mutations. An integrity model based on these two factors may be beneficial for accurately evaluating the prognosis of these patients.

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.

Objective: To compare the clinical effects of arthroscopic lateral retinacular proximal release and "L" type release for lateral patellar compression syndrome. Methods: Sixty four lateral patellar compression syndrome (LPCS) patients were recruited who had arthroscopic surgery during September 2004 to January 2019 at Department of Sports Medicine,Peking University Third Hospital by the same group of doctors and a retrospective comparative study was conducted accordingly. Among them,24 cases underwent the traditional proximal release of lateral patellar retinaculum (traditional group),including 7 males and 17 females with an age of (42.9±14.6)years(range:23 to 72 years); 40 cases were treated with novel lateral retinacular release of "L" type release revised based on the previous experiences (novel group), consisting of 12 males and 28 females with an age of (54.9±13.1) years (range:28 to 76 years).All the patients participated surveys for the visual analogue scale (VAS),Lysholm score and International Knee Documentation Committee (IKDC) knee function subjective evaluation before and after the operation. The comparison of scores within groups was performed by Wilcoxon test,and comparison between groups was performed by Mann-Whitney U test and Chi-square test. Multivariate analysis was used to evaluate the related factors affecting each score. Results: The follow-up durations of traditional group and novel group were (12.6±1.0) years (range:11.7 to 15.3 years) and (2.2±1.0)years(range:1.0 to 4.4 years) respectively. At the last follow-up,VAS(0(1.0)to 6.0(2.0),Z=-5.471,P<0.01),Lysholm score(98.0(10.0)to 48.0(40.0),Z=-5.511,P<0.01),and IKDC score(82.8(11.2)to 37.4(18.5),Z=-5.444,P<0.01) in novel group were statistically significantly improved,and the postoperative excellent rate of Lysholm score was 97.5% in general. There was no significant difference in the changes of the three scores (P>0.05) between the traditional group and the novel group. However,20.8% (5/24)patients in the traditional group reported significant weakness of the knee extension after surgery,while no such complain was received in the novel group (P<0.01).The results of univariate analysis showed that surgical method was a related factor affecting the changes of VAS before and after surgery (P<0.05).The results of multivariate analysis showed that whether or not with osteoarthritis and operation type were independent factors affecting the changes of Lysholm and IKDC scores (P<0.05). Conclusions: The long-term effect of arthroscopic lateral retinacular release for the treatment of LPCS is satisfactory. Compared with the traditional proximal release surgery,the "L" type release can effectively avoid the complication of significant weakness of the knee extension significantly.
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.

Objective: To investigate the early clinical effects of home-based mobile health intervention on knee joint function after anterior cruciate ligament (ACL) reconstruction. Methods: This was a prospective randomized controlled trial. Patients undergoing arthroscopic ACL reconstruction alone at the Institute of Sports Medicine, Peking University Third Hospital from April 2019 to December 2019 were elected in the trial. Patients were divided into the intervention group and the control group according to random number method. The control group only received the guidance of the traditional paper rehabilitation schedule, while the intervention group also received personalized guidance of electronic rehabilitation prescription and follow-up notice delivered by a WeChat Mini Program Rehabilitation Cloud Platform in addition to the traditional guidance. Joint range of motion (ROM), visual analogue scale (VAS) and thigh circumference difference were assessed before and after the operation. Independent sample t test or Mann-Whitney U test was used for comparison of data between groups, and chi-square test was used for comparison of enumeration data. Results: One hundred and twenty five patients were enrolled in the trial, including 99 males and 26 females, with an average age of 29.0 years (range:18 to 45 years) and an average body mass index of 24.8 kg/m(2) (range:15.8 to 36.6 kg/m(2)). At 6 weeks, follow-up was available in 106 cases the target-reach rate of ROM in control group was 42.6%(23/54), which was 67.3%(35/52) in the intervention group, the difference was statistically significant (χ(2)=6.53, P=0.01); VAS of the intervention group was 2.5(2.0), lower than that of the control group 3.0(2.0)(M(Q(R))), the difference was statistically significant (Z=-2.06,P=0.04); And the thigh circumference difference of the intervention group was 2.0(2.0)cm lower than that of the control group 3.0(1.8)cm, the difference was statistically significant (Z=-3.00, P<0.01). Conclusion: Mobile health intervention can improve the early postoperative rehabilitation effect after ACL construction and the ROM of the knee joint, and reduce the bent-knee pain along with the thigh circumference difference.

Fast radio bursts (FRBs) are millisecond-duration radio transients of unknown physical origin observed at extragalactic distances1-3. It has long been speculated that magnetars are the engine powering repeating bursts from FRB sources4-13, but no convincing evidence has been collected so far14. Recently, the Galactic magnetar SRG 1935+2154 entered an active phase by emitting intense soft γ-ray bursts15. One FRB-like event with two peaks (FRB 200428) and a luminosity slightly lower than the faintest extragalactic FRBs was detected from the source, in association with a soft γ-ray/hard-X-ray flare18-21. Here we report an eight-hour targeted radio observational campaign comprising four sessions and assisted by multi-wavelength (optical and hard-X-ray) data. During the third session, 29 soft-γ-ray repeater (SGR) bursts were detected in γ-ray energies. Throughout the observing period, we detected no single dispersed pulsed emission coincident with the arrivals of SGR bursts, but unfortunately we were not observing when the FRB was detected. The non-detection places a fluence upper limit that is eight orders of magnitude lower than the fluence of FRB 200428. Our results suggest that FRB-SGR burst associations are rare. FRBs may be highly relativistic and geometrically beamed, or FRB-like events associated with SGR bursts may have narrow spectra and characteristic frequencies outside the observed band. It is also possible that the physical conditions required to achieve coherent radiation in SGR bursts are difficult to satisfy, and that only under extreme conditions could an FRB be associated with an SGR burst.
ABSTRACT
We study the generation and propagation of hyperbolic secant solitons, Peregrine solitons, and various breathers in a coherently prepared three-level atomic system, where two lower states are coherently prepared prior to the injection of a strong pump field and a weak probe field. We show that a flat dispersion without gain and loss along with a large Kerr nonlinearity can be achieved in a broad range of probe field frequency. Moreover, optical hyperbolic secant solitons can be easily achieved in such a broad range at a very low light intensity and propagate stably. Due to the enhanced Kerr nonlinearity, we also show that it is possible to generate optical rogue waves and breathers with very weak light stimulus, which is three orders of magnitude smaller than that used in nonlinear fibers. Because the gain/absorption is negligible and the quantum noise of the probe field can be significantly suppressed, our work may pave the way for realizing solitons, rogue waves, and breathers at the quantum level.
ABSTRACT
We theoretically investigate the quantum phase transition in the collective systems of qubits in a high quality cavity, where the cavity field is squeezed via the optical parametric amplification process. We show that the squeezed light induced symmetry breaking can result in quantum phase transition without the ultrastrong coupling requirement. Using the standard mean field theory, we derive the condition of the quantum phase transition. Surprisingly, we show that there exists a tricritical point where the first- and second-order phase transitions meet. With specific atom-cavity coupling strengths, both the first- and second-order phase transition can be controlled by the nonlinear gain coefficient, which is sensitive to the pump field. These features also lead to an optical switching from the normal phase to the superradiant phase by just increasing the pump field intensity. The signature of these phase transitions can be observed by detecting the phase space Wigner function distribution with different profiles controlled by the squeezed light intensity. Such superradiant phase transition can be implemented in various quantum systems, including atoms, quantum dots, and ions in optical cavities as well as the circuit quantum electrodynamics system.
ABSTRACT
Objective: To explore the clinical effect of nutritional and psychological intervention combined with pulmonary rehabilitation exercise on patients with chronic obstructive pulmonary disease (COPD). Methods: A total of 260 patients with COPD admitted to the Sixth Affiliated Hospital of Kunming Medical University from October 2014 to October 2017 were included. They were divided into mild, moderate, severe and extremely severe groups according to forced expiratory volume in one second predicted (FEV(1)%prep) of pulmonary function. The patients were divided into control group and comprehensive management group according to the random number table method. The control group was given routine treatment including smoking quitting persuasion, vaccination, oxygen therapy and standardized medication. The comprehensive management group was given additional nutritional support, psychological intervention and pulmonary rehabilitation exercise. The data of the lung function indexes (FEV(1)%prep, FEV(1)/FVC, PaO(2), PaCO(2)), nutritional indexes [body mass index (BMI), albumin (ALB), nutrition risk screening (NRS)2002], anxiety and depression scores, 6-minute walking distance (6MWD), modified medical research council (mMRC) dyspnea scale, COPD assessment test (CAT), St. George's score, and frequency of acute exacerbations were compared between two groups after 12 months of treatment. Results: After 12 months' treatment, PaO(2) in the comprehensive management group was significantly higher than that in the control group [(51.1±7.2) vs (47.0±9.1) mmHg] (1 mmHg=0.133 kPa); Nutritional risk (NRS2002) decreased obviously [(1.1±1.1) vs (2.2±1.0)]; anxiety score [(4.1±2.2) vs (5.6±2.7)]; depression score [(4.1±2.0) vs (5.5±2.6)] and St. George's score [(36.8±20.8) vs (48.6±19.5)] decreased significantly (P<0.05). And the 6MWD was significantly farther [(368.4±72.0) vs (343.4±75.0) m] in management group. The frequency of acute exacerbations was significantly reduced in the mild, moderate and severe groups (P<0.05). But there was no significant difference in FEV(1)%prep, FEV(1)/FVC, PaCO(2), BMI, ALB, mMRC score and CAT score. Conclusion: Nutritional and psychological intervention combined with pulmonary rehabilitation exercise can reduce the nutritional risk and the frequency of acute exacerbations in patients with COPD, relieve anxiety and depression state and improve the quality of life.

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.

Objective: To evaluate the prognostic significance of combining ISS-â ¢ and high risk cytogenetic abnormalities [HRCAs, including 1q gain/amplification and del (17p) ] in patients with newly-diagnosed multiple myeloma (NDMM) . Methods: The clinical characteristics and relevant variables were retrospectively analyzed in a total of 270 NDMM patients diagnosed between November 2009 and May 2018. ISS-â ¢ stage and HRCAs [detected by FISH, including 1q gain/amplification and del (17p) ] were defined as risk factors (hit) . Based to the number of hit per case, these patients were divided into four groups carrying 0 to 3 risk factors, respectively. Progress-free survival (PFS) and overall survival (OS) were then analyzed using the Kaplan-Meier estimator. Results: Patients who carried single hit (n=120, 44.4%) had shorter median PFS (23.0 vs 28.9 months; P>0.05) and OS (42.3 vs 53.7 months; P>0.05) than those with no risk factors (n=66, 24.4%) . Of note, the outcome of patients who had two or more risk factors (double/triple, n=84, 31.1%) was much worse than those with either no or one risk factor, indicated by significantly reduced median PFS (14.5 months; HR=1.584, 95%CI 1.082-2.319; P=0.003 for double/triple vs single hit) and OS (18.4 months, HR=2.299, 95%CI 1.485-3.560; P<0.001 for double/triple vs single hit) . Strikingly, patients who had three risk factor (triple hit, n=5, 1.9%) displayed the poorest survival with extraordinarily shorter PFS (0.9-15.1 months) and OS (0.9-18.9 months) compared to those carrying two risk factors (double hit) . Analogous results were obtained when different combinations of ISS stages and HRCAs were analyzed. Conclusion: These results suggest a potential but rather important role of combining multiple (e.g. double or triple) adverse factors determined via the routine ISS staging and FISH detection of cytogenetic abnormalities in risk stratification and prognostic prediction, which might be helpful to identify high risk patients more precisely at diagnosis. It also raised a possibility that a small group of ISS-â ¢ patients carrying both 1q gain/amplification and del (17p) might represent an "extremely-high risk" subset of MM.

Objective: To investigate the mid-term efficacy of extracapsular arthroscopic surgery for refractory tennis elbow and explore prognostic factors. Methods: A retrospective study of 38 patients suffered from refractory tennis elbow and underwent extracapsular arthroscopic surgery performed by the same group of doctors during March 2012 to January 2016 at Institute of Sports Medicine, Peking University Third Hospital. There were 15 males and 23 females with age of 44.2 years(range: 32-59 years). Fifteen cases on the left and 23 cases on the right. Visual analogue scale(VAS), Mayo elbow performance score and Disability of Army, Shoulder and Hand (DASH) score were collected preoperatively and postoperatively, and compared by paired-t test. Independent sample t test, χ(2) test, multivariate logistic regression were used to analyze the relationship between scores and various potential influencing factors. Results: All 38 patients were followed up for 24 months. There was no complication such as infection or nerve injury recorded. VAS decreased from 7.0(1.2) (M(Q(R))) preoperative to 0(1) (Z=-5.40, P=0.00), Mayo increased from 55(26) to 100(0) (Z=-5.38, P=0.00),DASH decreased from 56.7(27.3) to 0.8(5.8)(Z=-5.37,P=0.00). The Mayo elbow performance score was excellent in 36 cases (94.7%) and good in 2 cases (5.3%). Women was significantly associated with poor prognosis. Conclusions: The mid-term effect of extracapsular arthroscopic treatment of refractory tennis elbow is satisfactory with few postoperative complications. Women was associated with poor prognosis.

Objective: To examine the surgical method and clinical outcome of primary repair of chronic Achilles tendon rupture. Methods: From March 2012 to August 2017, clinical data of 35 consecutive patients with chronic Achilles tendon rupture who were treated with primary repair by the same doctor at Department of Sports Medicine, Peking University Third Hospital were retrospectively analyzed.There were 29 males and 6 females with age of (41.0±9.3)years(range:29-65 years), the follow-up period was (45.6±17.2) months(range:17-82 months). All the patients had unilateral tendon rupture with 22 cases on the left and 13 cases on the right.The preoperative and postoperative Visual Analogue Scale(VAS), American Orthopaedic Foot and Ankle Society Ankle-Hindfoot Score(AOFAS), the Victorian Institute of Sport Assessment-Achilles(VISA-A), the Achilles tendon Total Rupture Score(ATRS)and the Tegner Activity Score of patients were collected and compared by paired-t test. Results: Among 47 patients with chronic Achilles tendon rupture, 35 patients were followed up for (45.6 ± 17.2)months(range: 17-28 months). No serious postoperative complications such as infection or nerve damage and rerupture outcomes were reported. At the last follow-up,the VAS decreased from 1.0(2.0) (M(Q(R))) preoperative to 0.0(0.8)(Z=-3.586, P=0.00), AOFAS increased from 64.3±12.5 to 97.0±5.0(t=-14.359,P<0.001), VISA-A increased from 51.3± 9.8 to 87.8±18.0(t=- 17.656, P=0.00), Tegner increased from 0.9±0.3 to 4.6±1.7(t=- 12.524, P=0.00)and ATRS increased from 40.0±3.5 to 97.9±3.9(t=-64.133,P=0.00). Twenty-eight patients (80.0%) had returned to their preinjury activity levels, and 7 patients (20.0%) no longer participate in recreational sports. According to Arner-Lindholm curative effect evaluation criteria, 32 cases(91.4%)gained the excellent results, 1 case(2.9%) of good and 2 cases(5.7%) bad, and the percentage of the cases with the excellent or good results was 94.3%. All except 2 patients with bad results could perform a single-limb heel rise painlessly. Conclusions: Primary repair is an efficient approach for chronic Achilles tendon rupture. The mid-and-long curative effect is satisfactory and stable.Compared with other surgical techniques, operation is relatively simple and economical. The primary repair is considerably safe, with few serious complications such as infection or nerve damage and reruptures.

Objectives: To evaluate the clinical characteristics and prognosis of high risk cytogenetic abnormalities (HRCA) and various combinations of cytogenetic abnormality in patients with newly-diagnosed multiple myeloma (NDMM) . Methods: This retrospective study collected 182 NDMM patients in the First Affiliated Hospital of Jilin University between Nov. 2009 and May 2018. HRCA included 1q+, del (17p) , t (4;14) , and t (14;16) detected by FISH, and non-HRCA included del (13q) , t (11;14) detected by FISH. The clinical characteristics among three groups, including cases who carrying a single HRCA, 1 HRCA in combination with non-HRCA and cases carrying two or more HRCAs (double/triple-hit) were observed. Kaplan-Meier curve was used to analyze both progression-free survival (PFS) and overall survival (OS) for the three groups. Results: The survivals of patients with 1 HRCA in combination with non-HRCA were similar to those with two or more HRCAs (double/triple-hit) , the median PFS (mPFS) was 19.1 m vs 12.1 m (P=0.248) and median OS (mOS) was 29.6 m vs 29.3 m (P=0.774) . Furthermore, the prognosis of these two groups were both inferior to patients with a single HRCA, respectively. (mPFS: 32.2 m, P=0.040, P=0.001; mOS: 42.3 m, P=0.021, P=0.041) . Strikingly, both the mPFS and the mOS of patients with 1 HRCA in combination with non-HRCA (regardless of high risk or not) were significantly shorter than that of cases with a single HRCA (mPFS: 15.1 m vs 32.2 m, HR=2.126, 95%CI 1.176-3.843, P=0.005; mOS: 29.3 m vs 42.3 m, HR=1.442, 95%CI 0.705-2.950, P=0.011) . Conclusion: It is of prognostic significance value for detecting double/triple-hit based on FISH cytogenetics in NDMM.
