Abstract
Females with existing high-risk HPV (HR-HPV) infections remain at risk of subsequent multiple or recurrent infections, on which benefit from HPV vaccines was under-reported. We pooled individual-level data from four large-scale, RCTs of AS04-HPV-16/18 vaccine to evaluate efficacy and immunogenicity in females DNA-positive to any HR-HPV types at first vaccination. Females receiving the AS04-HPV-16/18 vaccine in the original RCTs constituted the vaccine group in the present study, while those unvaccinated served as the control group. Vaccine efficacy (VE) against new infections and associated cervical intraepithelial neoplasia (CIN) 2+ in females DNA-negative to the considered HR-HPV type but positive to any other HR-HPV types, VE against reinfections in females DNA-positive to the considered HR-HPV type but cleared naturally during later follow-up, and levels of anti-HPV-16/18 IgG were assessed. Our final analyses included 5137 females (vaccine group = 2532, control group = 2605). The median follow-up time was 47.88 months (IQR: 45.72-50.04). For the prevention of precancerous lesions related to the non-infected HR-HPV types at baseline, VE against HPV-16/18 related CIN 2+ was 82.70% (95% CI: 63.70-93.00%). For the prevention of reinfections related to the infected HR-HPV types following natural clearance, VE against HPV-16/18 12MPI was non-significant (p > .05), albeit robust immunity persisted for at least 48 months. Females with existing HR-HPV infections at first vaccination still benefit from vaccination in preventing precancers related to the non-infected types at baseline. VE against reinfections related to the infected types following natural clearance remains to be further investigated.

Abstract
PURPOSE The aim of this study was to compare the effectiveness of Buzzy® and DistrACTION® Cards in reducing children's pain and fear while taking venous blood samples. METHODS This research was designed as a randomized controlled experimental study. The study population consisted of children aged 6-12 years admitted to the Pediatric Rheumatology Diseases Polyclinic in a Faculty of Medicine in Germany. The sample of the study consisted of 96 children (Buzzy® = 32, DistrACTION® Cards = 32, control = 32) who met the patient selection criteria and agreed to participate in the study. The data were obtained using a Child and Family Information Form, the Children Fear Scale (CFS), and the Faces Pain Scale-Revised (FPS-R). The data were evaluated using the Pearson chi-square test, Kruskal-Wallis test, One-way ANOVA test with Bonferroni correction, and Fisher-Freeman-Halton. FINDINGS In the study, the average age of the children was 9.21 ± 2.15 years. The Buzzy® group had the lowest pain and procedural fear scores (self-report = 0.88 ± 1.13, 0.31 ± 0.47; parent report = 0.75 ± 0.98, 0.34 ± 0.48, and researcher report = 0.81 ± 1.00, 0.31 ± 0.54, respectively) than the DC, and control groups. CONCLUSIONS The Buzzy® method was effective in reducing venipuncture pain and fear in children. PRACTICE IMPLICATIONS Nurses can use the Buzzy® methods to help reduce venipuncture pain and fear in children. The clinical trial registration number is NCT05560074. (https://clinicaltrials.gov/ct2/show/study/NCT05560074).

Abstract
The human papillomavirus (HPV) vaccine is the first vaccine developed specifically targeting the prevention of cervical cancer. For more than 15 years, China has expedited a series of efforts on research and development of the domestically manufactured HPV vaccines, producing local population-based evidence, promoting free HPV vaccination from pilots, and launching action plans to tackle barriers in the scale-up of HPV vaccination. To further roll out the HPV vaccination program in China, several challenges should be addressed to support the steps forward. The availability of more locally manufactured HPV vaccines, pricing negotiation and local evidence supporting the efficacy of one-dose schedule would greatly alleviate the continued supply and financial constraints in China. Meanwhile, more attention should be paid to girls living in low-resource areas and males to ensure equal access to the HPV vaccination. Furthermore, linkage to secondary prevention and further real-world monitoring and evaluation are warranted to inform effective cervical cancer prevention strategies in the post-vaccine era.

Abstract
Objectives: To evaluate the effectiveness of cognitive behavior therapy for insomnia (CBT-i) in chronic insomnia patients in terms of the improvements of psychological and sleep diary parameters. Methods: Patients who met the diagnostic criteria of chronic insomnia, were divided into primary group or comorbid group. Both groups received standard CBT-i interventions. Psychological scales and sleep diaries were used to evaluate participants' severity of insomnia and psychological conditions related to insomnia at four time points: before intervention (baseline), immediate after intervention, 4 weeks and 16 weeks after intervention. Results: Both groups achieved significant improvements after intervention on psychological measurements and sleep diary parameters. Such improvements were maintained at 4-week and 16-week follow-ups. The sleep diary data indicated that by the end of the intervention, there were significant differences on sleep onset latency (51.72 min to 10.53 min in primary group, P<0.01; 59.26 min to 15.67min in comorbid group, P<0.01) and sleep efficiency (71% to 95% in primary group, P<0.01; 68% to 90% in comorbid group, P<0.01). There were differences on sleep onset latency (10.00 min vs. 13.93 min, P<0.05), total sleep time (355.71 min vs. 327.85 min, P<0.05) and sleep efficiency (95% vs. 91%, P<0.01) in primary group and comorbid group respectively. No differences were found on wake after sleep onset in the two groups. Conclusions: Chronic insomnia patients with or without comorbidities both have improvements after CBT-i. Sleep diary parameters rather than psychological measurements are different in two groups. Thus, CBT-i is an effective non-pharmaceutical therapy inpatients with chronic insomnia.

Abstract
Nitriles are potential soil pollutants from industrial wastewater. There has been increased demand for efficient process for nitrile degradation process. Nitrile hydratase (NHase) has been extensively used in the production of acrylamide and treatment of organocyanide contaminated industrial effluents. The NHase of Mesorhizobium sp., isolated from polyacrylonitrile activated sludge from fiber manufacturing wastewater treatment systems was studied in the whole bacterial cells. Different chemicals were added to observe the variation in the percentage of acrylonitrile converted into acrylamide. The result indicated that cobalt ions were the NHase cofactor and could increase the NHase activity. The addition of propionaldehyde, or butyraldehyde could enhance the acrylonitrile conversion rate. Therefore, acrylamide could be accumulated effectively and the percentage of acrylonitrile converted into acrylamide increased. Propionaldehyde was the most effective NHase activator. The percentage of acrylonitrile converted into acrylamide was nearly 100% at 3.8 h when propionaldehyde was added at about 207.4 mg/l. The addition of benzaldehyde was unable to increase the percentage of acrylonitrile converted into acrylamide. EDTA and acrylamide showed no effect on NHase activity. However, 0.1 mg/l of Ag2SO4 would slightly inhibit NHase activity, producing an acrylonitrile conversion rate of 492.9 mg/l with 54.9% converted at 29.1 h. The ability of the acrylonitrile biotransformation was completely inhibited if the Ag2SO4 concentration was above 0.5 mg/l.

Abstract
The Baylis-Hillman reaction of aldehydes with alpha,beta-unsaturated ketones can be drastically affected by the reaction temperature and Lewis bases. When the reaction was carried out at -78 degrees C using catalytic amounts of quaternary ammonium salts (R4N+X-, X = Cl, Br, I) as Lewis bases, in the presence of titanium(IV) chloride, the chlorinated aldol adduct 1 was obtained as the major product. Quaternary ammonium bromides and iodides (R4N+X-, X = Br, I) have higher catalytic activity than corresponding chlorides (R4N+Cl-). Quaternary ammonium fluorides (R4N+F-) do not have activity at all. The amounts of Lewis acid and quaternary ammonium salts used affect the reaction rate and product. A plausible reaction mechanism is proposed. If the reaction was carried out at room temperature (about 20 degrees C) in the presence of titanium(IV) chloride and quaternary ammonium salts (R4N+X-, X = Cl, Br, I), the elimination product 3, derived from 1, was formed as the major product.

Abstract
The theory of polymer coils shrinking in semi-dilute solution has recently been developed on polymer solution. The polymer solution from coils shrinking concentration Cs to uniform entangled concentt concentration C+ has been defined as semi-dilute solution. We experimentally investigated the electrophoretic migration behavior of 100 bp deoxyribonucleic acid (DNA) Ladder in hydroxypropyl methyl cellulose (HPMC) concentration ranging from 1.25 g/L to 16.06 g/L. The friction force mobility mu f is used to express the friction force that DNA will encounter in capillary electrophoresis. Our results indicate the division of polymer solution into three regions depending on the relationship of mu f and HPMC concentration and Ferguson plot. Resolutions of 200 bp/300 bp and 700 bp/800 bp show semi-dilute polymer solution suits large fragments and small fragments DNA separation respectively. the results confirm that the current polymer theory is valid under actual CE condition.

Abstract
The management of acute myoglobinuric renal failure, the major complication of rhabdomyolysis, continues to be a treatment dilemma for the clinician as limited therapeutic options are available. Previously, we have demonstrated that continuous arteriovenous hemofiltration (CAVH) is an effective technique for removing myoglobin in an animal model. In the present study, swine were administered four grams of equine myoglobin intravenously and underwent the continuous veno-venous hemofiltration (CVVH) procedure for six hours each. Animals were studied in each of the following groups: CVVH at a pump rate 100 ml/minute, CVVH at a pump rate 200 ml/minute and CVVH at a pump rate 100 ml/minute plus dialysis at a dialysate flow rate of one Liter/h. Once the filtering process was initiated there was a rapid and sustained production of ultrafiltrate in all groups. The amount of myoglobin excreted in the ultrafiltrate over the six-hour filtering period was 688, 948 and 570 mg which corresponded to 17, 24 and 14 percent of the administered dose, respectively, for the three treatments. In comparison to previous CAVH experiments, CVVH removed more circulating myoglobin and the addition of the dialysis component did not appear to improve removal. Based on these findings, it appears that the CVVH hemofiltration system is a viable option for the removal of systemic myoglobin.

Abstract
The optimal result of colorectal surgery is best achieved by adequate preoperative colon preparation, which should be simple, safe, rapid, and thoroughly clean with little or no discomfort at all for patients. Conventional mechanical preparation, though effective, is time-consuming and unpleasant for patients, therefore new methods have been frequently presented in recent literature to meet the above ideal. A prospective and randomized study was conducted to evaluate preoperative colon preparation in elective, nonobstructive colorectal surgery. Group I included 32 patients who received three-day diet control and enema, while group II included 42 patients who received one-day diet control and oral dulcolax. Both groups were given systemic antibiotics. The result favored group II because of its significantly less abdominal fullness, but the electrolyte change and bacteriologic study revealed no significant difference between two groups. Neither did they exhibit variance in the adequacy of bowel cleansing (81.3% in group I vs 81% in group II). It is therefore suggested that, without enema and with less abdominal fullness, oral dulcolax should be encouraged for colon preparation in colorectal surgery.

Abstract
A consecutive series of 28 patients with acutely obstructing carcinomas of the left colon and rectum were encountered during the last three years. Two patients treated by loop colostomy only were excluded from the study. Fifteen patients received a one-stage operation of immediate resection and primary anastomosis without proximal colostomy. The remaining 11 patients were treated by a conventional staged operation. The operative mortality and complications were similar in both groups. The duration of hospital stay in the former was half of that in the latter. Of nine patients treated by subtotal or total colectomy with primary anastomosis, the average number of bowel movements three months after surgery was 1.8 per day. Intraoperative colonic irrigation was performed in five patients of the one-stage group and permitted a safe primary anastomosis. The immediate results of the one-stage operation were surprisingly good. The authors propose it as the treatment of choice for the majority of patients with obstructing carcinomas of the left colon and rectum.
