Objective To explore the clinical characteristics and treatment scheme of periprosthetic joint infection(PJI)caused by Cutibacterium avidum(C.avidum).Methods The diagnosis and treatment process of a patient with PJI caused by C.avidum was summarized,and relevant literatures in the database were retrieved for review.Results A 65-year-old female patient with body mass index(BMI)of 31.1 kg/m2 underwent left humeral head prosthesis replacement surgery following a left proximal humerus fracture.Ten months after the surgery,the pa-tient exhibited poor wound healing and oozing,along with limited movement of the left shoulder joint,and was diag-nosed infection following shoulder arthroplasty.Patient underwent debridement of the infected lesion and removal of the prosthesis.The tissue,bone cement and prosthesis were cultured for C.avidum.Four literatures were re-trieved and screened,a total of 30 patients with PJI(28 cases hip joint infection and 2 cases shoulder joint infection)caused by C.avidum were reported through literature retrieval,and 78.6％(n=22)total hip arthroplasty(THA)surgeries were performed using direct anterior approach(DAA).The positive rate of preoperative joint fluid culture was 71.4％,29 cases underwent surgical combined with sensitive antimicrobials treatment.Except for one patient who had repeated infection and underwent three surgeries,other patients had a good prognosis.Conclusion PJI caused by C.avidum is mostly seen in THA patients who are obese and undergo DAA,with a few cases reported after shoulder arthroplasty.The high sensitivity of preoperative joint fluid culture provides an important basis for the development of surgical strategies and anti-infection protocols.

Objective To evaluate the effects of anterior cruciate ligament (ACL) reconstruction timing on the motor performance and proprioception by clinical evaluation as well as proprioception and motor performance tests on the patients more than 2 years after ACL reconstruction. Methods The patients who underwent ACL reconstruction in the National Institute of Sports Medicine,General Administration of Sport of China from January 2015 to January 2021 and met the inclusion criteria were followed up,and the postoperative data were collected retrospectively.Fifty-six patients who met the inclusion criteria were included in this study and categorized into two groups:early surgery (n=28,who underwent ACL reconstruction ≤3 weeks after injury) and delayed surgery (n=28,who underwent ACL reconstruction >3 weeks after injury).The basic information,clinical evaluation results,proprioception,and motor performance were compared between the two groups. Results The ACL return to sport after injury scale (ACL-RSI) score in the early surgery group was higher than that in the delayed surgery group [(68.68±22.04)scores vs. (55.82±24.87)scores,P=0.045].There was no difference in the range of motion of the knee joint,the positive rate of pivot shift test,or the scores of Tegner,Marx,Lysholm,knee injury and osteoarthritis outcome score (KOOS),and international knee documentation committee (IKDC) between the two groups (all P>0.05).Although there was no significant difference in range of motion of the knee joint between the two groups,the proportion of knee flexion and extension affected in the early surgery group was smaller than that in the delayed surgery group.Neither motor performance (isokinetic strength test,Y-balance test,and single-leg jump test) nor proprioception had difference between the two groups (all P>0.05). Conclusions Early ACL reconstruction outperformed delayed ACL reconstruction in improving the psychological health,emotions,and confidence in returning to sport,accelerating functional recovery of the patients.The timing of ACL reconstruction has no significant effect on the short-term postoperative knee stability,knee function,motor performance,or proprioceptive recovery of the patients.Early ACL reconstruction is recommended for improving the clinical outcomes.

Objective To evaluate the effects of knee flexor and extensor strength on the subjective function and motor performance of knees after anterior cruciate ligament reconstruction. Methods A total of 53 patients who underwent anterior cruciate ligament reconstruction in the National Institute of Sports Medicine,General Administration of Sport of China from June 2015 to June 2021 and met the inclusion criteria were enrolled in this study.The patients were followed up time for at least 2 years.An isometric muscle strength test system was used to measure the strength of bilateral quadriceps and hamstring muscles.The patients were grouped according to whether the limb symmetry index (LSI) of peak torque of quadriceps and hamstring muscle reached 85% at an angular velocity of 60°/s.Specifically,26 patients were classified into group A (LSI≥85%) and 27 patients were classified into group B (LSI<85%).The subjective function and motor performance of knees were compared between the two groups. Results In terms of subjective function of knees,the international knee documentation committee (IKDC) score (88.76±9.93 vs. 81.08±12.57,P=0.017) and knee injury and osteoarthritis outcome score (KOOS) (86.27±8.96 vs. 80.22±11.31,P=0.036) were different between groups A and B.There was no significant difference in Lysholm score [95.0 (79.8,100.00) vs. 86.00 (66.00,100.00),P=0.238],ACL return to sports after injury scale score (66.08±22.25 vs. 61.12±23.53,P=0.434),Marx score [6.00 (4.75,7.00) vs. 6.00 (4.00,7.00),P=0.805] or Tegner activity score [8.00 (4.00,12.00) vs. 4.00 (2.00,12.00),P=0.566] between the two groups.In terms of motor performance,the single-leg triple hop LSI (0.92±0.13 vs. 0.81±0.18,P=0.016) and single-leg crossover hop LSI (0.96±0.12 vs. 0.84±0.22,P=0.021) showed significant differences between groups A and B,while there was no significant difference in single-leg hop LSI (0.90±0.18 vs. 0.79±0.25,P=0.116) between the two groups.In addition,there was no statistical significance in proprioception [30°:8.83±4.66 vs. 10.73±4.63,P=0.143;45°:6.94±3.82 vs. 7.66±3.93,P=0.504;60°:4.10 (3.20,4.72) vs. 3.90 (2.30,5.20),P=0.493] or Y-balance test results [anterior LSI:0.98 (0.84,1.02) vs. 0.94 (0.86,0.98),P=0.328;posterolateral LSI:1.00±0.08 vs. 0.97±0.07,P=0.249;posteromedial LSI:1.00 (0.97,1.03) vs. 0.96 (0.93,1.03),P=0.179] between groups A and B. Conclusion The patients with good symmetry of quadriceps and hamstring muscle strength after anterior cruciate ligament reconstruction had better subjective function and movement performance of knees than the patients with poor symmetry,which was mainly reflected in the IKDC score,KOOS,single-leg triple hop,and single-leg crossover hop.

This study aims to investigate the inhibitory effect of Pien Tze Huang(PZH) on enterovirus 71(EV71). To be speci-fic, chemiluminescence method was adopted to evaluate the toxicity of PZH to African green monkey kidney(Vero) cells and human rhabdomyosarcoma(RD) cells, and cytopathic effect(CPE) method to assess the inhibition on EV71-GFP reporter virus and EV71 C4 wild-type virus. The results showed that PZH had low cytotoxicity to Vero cells and RD cells, with the half-maximal cytotoxic concentration(CC_(50)) of about 0.691 3-0.879 2 mg·mL~(-1) for the two. In addition, PZH can effectively inhibit the replication of EV71 within the non-cytotoxic concentration range, and dose-dependently alleviate the cytopathic changes caused by virus infection, with the half-maximal effective concentration(EC_(50)) of 0.009 2-0.106 3 mg·mL~(-1). On the basis of the above results, the green fluorescent protein(GFP), indirect immunofluorescence assay(IFA), and median tissue culture infective dose(TCID_(50)) were employed to assess and verify the anti-EV71-GFP and anti-EV71 C4 activity of PZH. The results demonstrated that PZH can dose-dependently lower the expression of GFP by EV71-GFP and structural protein VP-1 by EV71 C4 and decrease the production of progeny infectious viruses. The EC_(50) of PZH for EV71-GFP and EV71 C4 was about 0.006 0-0.006 2 mg·mL~(-1) and 0.006 6-0.025 6 mg·mL~(-1), respectively. This study suggested that PZH may exert antiviral activity by acting on EV71 and interfering with the expression of VP-1. At the moment, there is still a lack of specific anti-EV71 drugs. This study proposed a new idea for the symptomatic treatment of EV71 infections such as hand-foot-mouth disease and verified an effective drug for the treatment of EV71 infections.

Since 2015 when the transmission of schistosomiasis was controlled in China, the country has been moving towards elimination of schistosomiasis, with the surveillance-response as the main interventions for schistosomiasis control. During the period of the 13th Five-Year Plan, the transmission of schistosomiasis had been interrupted in four provinces of Sichuan, Jiangsu, Yunnan and Hubei and the prevalence of schistosomiasis has been at the historically lowest level in China. As a consequence, the goal set in The 13th Five-Year National Schistosomiasis Control Program in China is almost achieved. However, there are multiple challenges during the stage moving towards elimination of schistosomiasis in China, including the widespread distribution of intermediate host snails and complicated snail habitats, many types of sources of Schistosoma japonicum infections and difficulty in management of bovines and sheep, unmet requirements for the current schistosomiasis control program with the currently available tools, and vulnerable control achievements. During the 14th Five-Year period, it is crucial to consolidate the schistosomiasis control achievements and gradually solve the above difficulties, and critical to provide the basis for achieving the ultimate goal of elimination of schistosomiasis in China. Based on the past experiences from the national schistosomiasis control program and the challenges for schistosomiasis elimination in China, an expert consensus has been reached pertaining to the objectives, control strategy and measures for The 14th Five-Year National Schistosomiasis Control Program in China, so as to provide insights in to the development of The 14th Five-Year National Schistosomiasis Control Program in China.

Ferroptosis is a form of iron-dependent regulated cell death. Evidence of its existence and the effects of its inhibitors on subarachnoid hemorrhage (SAH) is still lacking. In the present study, we found that liproxstatin-1 protected HT22 cells against hemin-induced injury by protecting mitochondrial functions and ameliorating lipid peroxidation. In in vivo experiments, we demonstrated the presence of characteristic shrunken mitochondria in ipsilateral cortical neurons after SAH. Moreover, liproxstatin-1 attenuated the neurological deficits and brain edema, reduced neuronal cell death, and restored the redox equilibrium after SAH. The inhibition of ferroptosis by liproxstatin-1 was associated with the preservation of glutathione peroxidase 4 and the downregulation of acyl-CoA synthetase long-chain family member 4 as well as cyclooxygenase 2. In addition, liproxstatin-1 decreased the activation of microglia and the release of IL-6, IL-1β, and TNF-α. These data enhance our understanding of cell death after SAH and shed light on future preclinical studies.

Objective:To understand the incidence trend and epidemiological characteristics of COVID-19 in Shaanxi province.Methods:The incidence data of COVID-19 reported in Shaanxi as of 22 February, 2020 were collected for an epidemiological descriptive analysis.Results:A total of 245 confirmed cases of COVID-19 were reported in Shaanxi. Most cases were mild (87.76%). As time passed, the areas where confirmed cases were reported continued to increase. The case number in Xi’an was highest, accounting for nearly half of the total reported cases in the province. The epidemic pattern in Shaanxi had gradually shifted from imported case pattern to local case pattern, and the transmission of local cases was mainly based on family cluster transmission. The confirmed cases from different sources had caused the secondary transmission in Shaanxi. After February 7, the number of reported cases began to fluctuate and decrease stably, indicating a decrease-to-zero period.Conclusions:At present, the overall epidemic of COVID-19 in Shaanxi has gradually been mitigated. However, considering the approaching of return to work and study and the increasing of imported cases from other countries, the prevention and control of COVIS-19 in Shaanxi will face new challenges.

Objective To understand Clonorchis sinensis infections in cats in Nanning City, so as to provide evidence for the control of the reservoir host of C. sinensis. Methods The cat livers were purchased from cat slaughterhouses in Nanning City. The cat gallbladder and liver were dissected, and liver flukes were collected and counted. Then, the worms were subjected to morphological observation, amplification of the ITS2 gene and sequencing. The species of the worms were identified using BLAST. Results A total of 105 cat livers were collected from two cat slaughterhouses, and 68 were detected with C. sinensis infections, with an infection rate of 64.76%. The highest burden was 980 worms in a single liver, and the mean burden was 72 worms in a liver. There were 3 types of liver flukes with various size and morphology, and all were identified as C. sinensis by means of morphological observation, ITS2 gene amplification, sequencing and sequence alignment. Conclusion There is a high infection rate of C. sinensi in marketed cats in Nanning City, and it is therefore suggested that targeted interventions should be intensified for the management of C. sinensis infections in cats.

Objective To analyze the epidemic situation of malaria and explore the targeted control strategy in Guangxi from 2011 to 2018. Methods The malaria surveillance data were collected in Guangxi Zhuang Autonomous Region from 2011 to 2018, and a descriptive method was employed to analyze the epidemiological features of the malaria cases. Results A total of 2 944 malaria cases were reported in Guangxi Zhuang Autonomous Region from 2011 to 2018, including a case with local infection (0.03%) and 2 943 imported cases (99.97%). There were 2 933 cases (99.63%) positive for Plasmodium confirmed by laboratory testing, including 2 166 cases (73.86%) with P. falciparum malaria, 388 cases (13.23%) with P. ovale malaria, 276 cases (9.41%) with P. vivax malaria, 40 cases (1.36%) with P. malariae malaria and 62 cases (2.11%) with mixed infections, and 11 clinically diagnosed cases (0.37%). The malaria cases were distributed in 91 counties (districts) of 14 cities in Guangxi, with the largest number of cases found in Nanning City (2 515 cases, 85.43%). The malaria cases were originated from 29 countries in Africa (94.67%), 7 countries in Southeast Asia (5.10%), one country in South America (0.07%), 2 countries in South Asia and China (0.10%). In African countries, most malaria cases were from Ghana (1 947 cases, 66.13%), and in Southeast Asian countries, most cases were from Myanmar (75 cases, 2.55%). Most malaria cases were young men, and 2 899 cases (98.13%) were male, while 2 583 cases (87.74%) were at ages of 20 to 49 years. Gold washing and mining was the predominant occupation (2 561 cases, 86.99%), and the malaria cases were reported in each month across the year, with the largest number of cases detected in June (665 cases, 22.59%), while no season-specific distribution was found. There were 1 431 cases (48.61%) reported by disease control and prevention institutions, 1 511 cases (51.30%) reported by medical institutions, and 2 cases (0.07%) reported by inspection and quarantine institutions. During the period from 2011 to 2018, there were 6 deaths of imported malaria cases in Guangxi, and no secondary cases were reported. Conclusions The epidemic situation of local malaria has been effectively controlled in Guangxi; however, there is a great challenge for the management of overseas imported malaria. Strengthening the monitoring and management of migrant labors is the key to consolidate the achievements of malaria elimination.
