Abstract
Objective: To compare the differences of hip offset and rotation center reconstruction between robot-assisted and manual total hip arthroplasty (THA). Methods: Patients underwent robot-assisted and manual THA from May to September of 2020 in the First Affiliated Hospital of Chongqing Medical University were enrolled in this study. The patients included 27 patients (28 hips) in robot-assisted THA (rTHA) group and 29 patients (31 hips) in manual THA (mTHA) group. In rTHA group, there were 16 males and 11 females, with a mean age of (59±13) years. In mTHA group, there were 18 males and 11 females, with a mean age of (63±14) years. Basic information, including gender, age, body mass index (BMI), diagnosis and functional scoring etc, were recorded. In rTHA group, Mako robot system was used for preoperative planning, intraoperative real-time location and navigation. In mTHA group, traditional preoperative template design and surgical procedure were carried out. Operation time and functional scoring were compared postoperatively. Femoral offset, acetabular offset, global offset, rotation center changes in vertical and horizontal directions were measured on pelvis X-ray and analyzed. The correlation between intraoperative feedback of global offset change in robot system and postoperative measured global offset were analyzed. Results: Operation time in rTHA group was (80±10) min, which was statistically longer than that in mTHA group ((58±18) min, P<0.001). With 6 months' follow-up, the Harris scoring in rTHA group was 94.9±2.8, which was statistically higher than that in mTHA group (93.1±2.8, P=0.017), however there was no statistic difference in WOMAC scoring between rTHA and mTHA group (7.0±3.8 vs 7.1±2.4, P=0.840). Absolute global offset change within 5 mm, 5-10 mm and lager than 10 mm were 71.4%(20/28), 28.6%(8/28) and 0 in rTHA group, which were 45.2%(14/31), 29.0%(9/31) and 25.8%(8/31) in mTHA group (all P<0.05). A positive relation was found between intraoperative feedback of global offset change in robot system and postoperative measured global offset in rTHA group (r=0.77, P<0.001). It was found that rotation center changes concentrated in outer upper quadrant in both groups, and rotation center change in rTHA group concentrated mainly in the area less than 10 mm, however, rotation center change in mTHA group was more dispersive compared with rTHA group. Conclusion: rTHA may accurately reconstruct hip offset and rotation center, intraoperation feedback of global offset change may be an effective reference.

Abstract
Objective: To evaluate the efficacy and safety of oseltamivir in the treatment of suspected influenza in children. Method: A multicenter, randomized and open-label trial was conducted among 229 individuals with suspected influenza which were collected from the clinic of 5 hospitals in Guangdong province (Guangzhou Women and Children's Medical Center, Shenzhen Baoan District Maternity and Child Care Service Center, the Second Affiliated Hospital of Shantou University Medical College, Dongguan Maternity and Child Care Service Centre, Yuexiu District Children's Hospital of Guangzhou) from April to July 2015. They were randomized either to oseltamivir group (oseltamivir 30-75 mg, twice daily for 5 days) or control group who were given symptom relief medicines for 5 days. Result: No significant difference was found between two groups in influenza symptoms of the patients before the treatment(P>0.05). Altogether 229 individuals (114 in oseltamivir group, 115 in control group) were analyzed for efficacy, in which 73 individuals (42 oseltamivir, 31 control), 31.9%, were identified as influenza-infected through laboratory test. No significant difference was found between the two groups in the duration of fever although shortened. In the 229 individuals , the cumulative alleviation proportion between oseltamivir and control group was not significantly different (P>0.05): the median duration of illness was 69.9 hours (95% CI 65.3-91.5) in oseltamivir group and 75.4 hours (95%CI 63.9-91. 7) in control group; the median duration of fever was 40.4 hours (95%CI 31.5-53.4) in oseltamivir group and 44.0 hours (95%CI 33.2-50.0) in control group. In the 73 individuals, the cumulative alleviation proportion between oseltamivir and control group was significantly different (P<0.05). The median duration of illness was 61.2 hours (95%CI 48.0-121. 0) in oseltamivir group, being significantly shorter than that of 116.0 hours (95%CI 91.5-175.0) in control group. But it was not significantly different that the median duration of fever was 32.8 hours (95%CI 24.0-47.0 ) in oseltamivir group and 55.8 hours (95%CI 43.6-78.3 ) in control group (P>0.05). And the median duration of fever in 60 individuals (38 oseltamivir, 22 control) was significantly different between two groups(P<0.05), who had finished a course of taking oseltamivir in the 73 individuals, 34.8 hours (95%CI 24.0-48.5 ) in oseltamivir group being significantly shorter than that of 53.3 hours (95%CI 43.6-104.0 ) in control group. There was certain difference in side effects rate between the two groups (oseltamivir 10%, control 2%, P<0.05). The main side-effects were gastrointestinal symptoms (stomachache, diarrhea, poor appetite, vomiting). Conclusion: The duration of illness and fever in suspected influenza patients treated with oseltamivir was shorter than those in the patients treated with no oseltamivir, the difference was not statistically significant, when 31.9% was confirmed with positive result of virus test in suspected influenza in children. But in these patients with positive result of virus test, the duration of illness was significantly shortened with treatment with oseltamivir as compared with no treatment with oseltamivir, and it would be better if full oseltamivir course was completed for reducing the duration of fever. Oseltamivir treatment was safe with mild side effects.

Abstract
If adolescents do not receive appropriate assistance in quitting smoking, they are highly likely to become regular smokers when they enter adulthood. Thus, an effective smoking-cessation program is required. A program was designed based on both the smoking-cessation barriers reported by students and effective strategies derived from the literature. We assigned 143 student smokers from 6 vocational high schools to intervention (n=78) and comparison groups (n=65). Data were collected at the baseline, the end of the program, and 1- and 4-month follow-up time points. For the intervention group, the smoking-abstinence rates confirmed using the urine cotinine test were 22.73% at the end of the program and 20.75% at the 4-month follow-up point. Days smoked in the past month, number of cigarettes smoked per day, and the Fagerström Test for Nicotine Dependence score of the intervention group decreased at all of the time points. The group differences in these variables were statistically significant; the magnitude of effect sizes ranged from 0.44 to 0.95. Multicomponent programs addressing smoking-cessation barriers that students encounter can help adolescents quit smoking.

Abstract
Bell pepper (Capsicum annuum L.) plants exhibiting systemic mild mosaic, vein yellowing, and leaf malformation were collected from Puli City in 2006. Double-antibody sandwich (DAS)-ELISA was used to test these samples for Chilli veinal mottle virus (ChiVMV) infection using polyclonal antibodies. In addition, Chenopodium quinoa, C. amaranticolor, and Nicotiana benthamiana plants were mechanically inoculated with sap extracted from collected samples. Ten days postinoculation, chlorotic local lesions were observed on inoculated leaves of C. quinoa and C. amaranticolor plants, whereas, systemic mosaic and foliar distortion symptoms were developed on upper leaves of N. benthamiana plants. The DAS-ELISA test showed that field-collected pepper samples and inoculated leaves of C. quinoa and C. amaranticolor were infected with ChiVMV, while N. benthamiana with mosaic symptoms did not react with ChiVMV antibodies. To confirm ChiVMV, field-collected samples as well as mechanically inoculated plants were tested by reverse transcription (RT)-PCR using the potyvirus degenerate primers Hrp5/Pot1 (2). Amplified RT-PCR products were cloned and sequenced. Sequence analysis of amplified fragments (1.4 kb) revealed that field-collected pepper samples were infected with ChiVMV and Pepper mottle virus (PepMoV). The DNA fragment amplified from C. quinoa and C. amaranticolor showed high (99.2%) sequence identities with the CP gene of ChiVMV (3) (GenBank Accession No. AM909717). However, amplicons obtained from N. benthamiana plants (GenBank Accession No. HQ329082) that showed mosaic symptoms showed 83.6% to 98.7% nucleotide identities with PepMoV (GenBank Accession Nos. AB126033, AF227728, AF440801, AF501591, EU586133, and M96425). Next, a pure isolate of PepMoV was established on N. benthamiana by mechanical inoculation of diluted plant sap obtained from a PepMoV-infected N. benthamiana plant. Bell pepper plants inoculated with the Taiwan isolate of PepMoV developed mosaic and leaf distortion symptoms. Antiserum against the PepMoV Taiwan isolate was subsequently prepared by immunizing rabbits with purified virus particles. Using the prepared antiserum and specific primers (1) to detect PepMoV, ChiVMV, and Pepper veinal mottle virus (PVMV), three viruses could be readily detected and differentiated from diseased bell peppers in the field. In a survey done in 2007, 18 of 33 pepper samples from southern Taiwan were found with mixed infections of PepMoV and ChiVMV, seven samples were infected with PepMoV and PVMV, five samples were infected with PVMV, and another three samples were infected with ChiVMV. To our knowledge, this is the first report of the occurrence of PepMoV in bell peppers in Taiwan. References: (1) Y. H. Cheng et al. Plant Dis. 93:107, 2009. (2) S. S. Pappu et al.

Abstract
The full-length genome of a potyvirus, previously known as sunflower chlorotic spot virus isolate SF-1 (SCSV-SF-1) which causes novel symptoms on sunflowers (Helianthus annuus), was sequenced and analyzed. The genome of SCSV-SF-1 is 9,741 nucleotides long, encoding a polyprotein of 3,071 amino acids containing the consensus motifs of potyviruses. Sequence comparison revealed that the 3'-terminus of SCSV-SF-1 shared over 96% similarities with isolates of Bidens mottle virus (BiMoV). However, SCSV-SF-1 has a very narrow host range, excluding the diagnostic host species for BiMoV, Bidens pilosa and Zinnia elegans. Therefore, SCSV-SF-1 is a distinct isolate of BiMoV. This is the first report of the full-length nucleotide sequence of BiMoV infecting sunflower in Taiwan.

Abstract
Asbestosis is a fibrotic lung disease resulting from inhalation of asbestos fibres. Its pathogenesis is poorly understood but probably involves stimulation of fibroblast proliferation and collagen production by mediators released from inflammatory and resident lung cells. In vitro studies have implicate PDGF, TNF-alpha, IGF-1, TGF-beta, and IL-1 in asbestosis, but the role of these mediators in vivo is not known. This study aimed to characterize mediators in bronchoalveolar lavage (BAL) fluid from patients exposed to asbestos with (n = 24) or without (n = 34) asbestosis, compared with ten normal subjects. Human lung fibroblasts were exposed to serial dilutions of BAL fluids and the effects on fibroblast proliferation were assessed. The median mitogenic activity of BAL fluid from asbestos-exposed (17 per cent above medium control, range 3-44 per cent) and asbestosis (14 per cent, range 2-60 per cent) groups was higher than that of BAL fluid from controls (10 per cent, range 2-20 per cent; P < 0.01 and P < 0.05, respectively), but there was no significant difference between the patient groups. The mitogenic activity of BAL fluids was not reduced by incubation with neutralizing antibodies to PDGF-AA, PDGF-AB, PDGF-BB, TNF-alpha, IGF-1, and IL-1 beta. We conclude that BAL fluids from patients exposed to asbestos contain mitogens for human lung fibroblasts, but that PDGF, TNF-alpha, IGF-1, or IL-1 beta do not contribute to this activity.
