Objective:To investigate the effects of montelukast sodium combined with compound methoxyphenamine on airway inflammation, intercellular adhesion molecule-1 (ICAM-1), toll-like receptor 4 (TLR4), and soluble programmed death ligand 1 (sPD-L1) levels in patients with post-infection cough.Methods:A total of 200 patients with post-infection cough who received treatment at The 903 Hospital of the PLA Joint Logistics Support Force from January to December 2023 were included in this randomized controlled study. The patients were divided into an observation group ( n = 100) and a control group ( n = 100) using the random number table method. The control group received oral administration of compound methoxyphenamine capsules, while the observation group received oral administration of montelukast sodium in addition to compound methoxyphenamine capsules. Both groups were treated for 7 days. The therapeutic effects as well as daytime and nighttime cough scores, airway inflammation change, serum ICAM-1, TLR4, and sPD-L1 levels, and Leicester Cough Questionnaire scores were compared between the two groups. Results:The total effective rate in the observation group was 95% (95/100), which was significantly higher than that in the control group [84% (84/100), Z = 2.49, P < 0.05]. After treatment, the daytime and nighttime cough scores in the observation group were (1.24 ± 0.31) points and (1.02 ± 0.31) points, respectively, which were significantly lower than those in the control group [(2.17 ± 0.65) points, (1.94 ± 0.47) points, t = 12.91, 16.34, both P < 0.001]. Serum levels of hypersensitive C-reactive protein, interleukin-8, tumor necrosis factor-alpha in the observation group were (8.84 ± 2.21) mg/L], (82.34 ± 13.24) mg/L, and (78.94 ± 13.24) ng/L, respectively, which were significantly lower than those in the control group [(12.76 ± 2.53) mg/L, (127.18 ± 35.17) mg/L, (102.31 ± 21.08) ng/L, t = 11.67, 11.93, 9.39, all P < 0.001]. The ICAM-1 and TLR4 levels in the observation group were (178.32 ± 21.23) μg/L and (7.45 ± 2.32) ng/L, respectively, which were significantly lower than those in the control group [(247.18 ± 25.64) μg/L, (19.98 ± 4.53) ng/L, t = 20.69, 24.62, both P < 0.001], while sPD-L1 level in the observation group [(2.34 ± 0.37) ng/L] was significantly higher than that in the control group [(1.72 ± 0.41) ng/L, t = -11.23, P < 0.001]. The quality-of-life scores in the observation group for social [(2.61 ± 0.25) points], psychological [(6.56 ± 0.45) points], physical [(7.65 ± 0.72) points], and total score [(16.81 ± 2.51) points] were significantly higher than those in the control group [(2.14 ± 0.30) points, (5.44 ± 0.52) points, (6.07 ± 0.65) points, (13.74 ± 2.68) points, t = 12.04, 16.29, 16.29, 8.36, all P < 0.001]. Conclusion:Montelukast sodium combined with compound methoxyphenamine is highly effective in treating post-infection cough in patients. The combined therapy can reduce airway inflammation, lower ICAM-1 and TLR4 levels, and increase sPD-L1 levels.

Objective To construct a non-drug intervention program for acute chemotherapy-related nausea and vomiting in children with cancer and to evaluate its efficacy.Methods Through literature review and Delphi expert correspondence,a non-drug intervention program for acute chemotherapy-related nausea and vomiting in children with cancer was constructed.By the convenience sampling method,200 consecutive children who received chemotherapy in the neurosurgery department of a tertiary children's hospital in Zhejiang province from February 1 to October 31,2023 were included as the application subjects,with 100 cases in an experimental group and 100 cases in a control group.The experimental group applied the non-drug intervention program of acute chemotherapy-related nausea and vomiting in children with cancer,and the routine measures were applied in the control group.The incidence of nausea and vomiting,severity of vomiting,compliance rate of normal sleep duration and incidence of negative emotions were compared between the 2 groups.Results The recovery rate of the valid questionnaire in 2 rounds of expert letter inquiry was 100％,and the expert authority coefficient was 0.836.The Kendall harmony coefficients were 0.471 and 0.820(P＜0.001),and the final non-drug intervention program for pediatric acute chemotherapy-related nausea and vomiting included 5 primary,14 secondary and 18 tertiary items.The results showed that the incidence of nausea,vomiting and negative emotions in the experimental group were lower than that in the control group,with statistically significant differences(P＜0.05).The severity of vomiting was less than it in the control group,with statistically significant difference(P＜0.05).The standard rate of normal sleep time was higher than that of the control group,and the difference was statistically significant(all P＜0.05).Conclusion The non-drug intervention program of chemotherapy-related nausea and vomiting in children is scientific and feasible,and the implementation of the program can reduce the incidence of nausea,vomiting and negative emotions,reduce the severity of vomiting,and improve the standard rate of normal bedtime in children.

Objective:To correlate blood lipids and body mass index (BMI) with Helicobacter pylori (Hp) infection. Methods:A total of 303 participants who underwent physical examinations at The 903 Hospital of PLA Joint Logistics Support Force from May 2022 to May 2023 were included in this case-control study. These patients were divided into an Hp-infected group ( n = 97) and a non-Hp-infected group ( n = 206) based on whether they had Hp infection or not. Participants' body height and weight were recorded, and BMI was calculated. The levels of four blood lipid indicators were determined using an automatic biochemical analyzer. The distribution of different BMIs and abnormal statuses of these four blood lipid indicators were compared between the two groups. Spearman correlation analysis was used to analyze the correlation between Hp infection and these four blood lipid indicators. A multivariate logistic regression model was applied to analyze the influential factors for Hp infection. Results:The number of participants who had 24 kg/m 2 ≤ BMI < 28 kg/m 2 [39.17% (38/97)] and the number of participants who had BMI ≥ 28 kg/m 2 [10.31% (10/97)] in the Hp-infected group was significantly higher than those in the non-Hp-infected group [19.90% (41/206) and 2.43% (5/206), χ2 = 12.71, 7.11, P < 0.001, 0.008]. The decrease rate of high-density lipoprotein cholesterol (HDL-C), increase rate of low-density lipoprotein cholesterol (LDL-C), increase rate of triglyceride (TG), and increase rate of total cholesterol (TC) in the Hp-infected group were 23.71% (23/97), 31.96% (31/97), 17.53% (17/97), and 22.68% (22/97), respectively, which were significantly higher than 9.22% (19/206), 11.17% (23/206), 7.28% (15/206), and 8.74% (18/206) in the non-Hp-infected group ( χ2 = 11.59, 19.47, 7.33, 11.19, P = 0.001, < 0.001, 0.007, 0.001). The Spearman analysis showed that Hp infection was linearly positively correlated with BMI, LDL-C, TG, and TC ( r = 0.571, 0.519, 0.473, 0.535, all P < 0.001), while it was linearly negatively correlated with HDL-C ( r = -0.628, P < 0.001). Multivariate logistic regression analysis showed that BMI ≥ 24 kg/m 2, decreased HDL-C, increased LDL-C, elevated TG, and elevated TC are independent risk factors for Hp infection. Conclusion:Blood lipids and BMI are closely associated with Hp infection, and abnormal blood lipids and elevated BMI are independent risk factors for Hp infection.

Objective To screen the distribution frequency of Mur blood group among voluntary blood donors in Hezhou,Guangxi,and further analyze the molecular basis of of Mur antigen positive samples.Methods The Mur pheno-type of voluntary blood donors in Hezhou was serologically screened using microplate method,and the distribution frequency of Mur antigens in different ethnic groups was analyzed.Genetic typing was performed on these positive samples with PCR-SSP method to verify the accuracy of the serological method,and the genetic background was sequenced and analyzed.Re-sults Among 3 298 samples from voluntary blood donors in Hezhou,432(13.10%,432/3 298)were screened positive for Mur antigen,and PCR-SSP genotyping validation showed that all 432 samples were electrophoretic positive.Among them,the proportion of Han blood donors with positive Mur antigen was12.79%(331/2 587),Yao ethnic group was13.25%(64/483),Zhuang ethnic group was 16.51%(36/218),and no statistically significant difference was found in the three groups(P＞0.05).Further sequencing results showed that 428 samples were GYP(B-A-B)Mur,also known as GYP.Mur type(12.98%,428/3 298),the other 4 samples were GYP(B-A-B)Bun,also known as GYP.Bun type(0.12%,4/3 298).Conclusion The Mur blood type frequency is high in the voluntary blood donors in Hezhou,Guangxi,and is predominant characterized by GYP.Mur genotype.Due to ethnic integration,no significant difference was noticed in the frequency of Mur blood type distribution between Han,Zhuang and Yao population.Therefore,conducting extensive Mur blood group antigen and antibody testing in Hezhou is of great significance for ensuring clinical blood transfusion safety.

Objective: To investigate the association between parenting style and sleep problems among school aged children with autism spectrum disorder (ASD). Methods: A total of 98 children with ASD aged 6-10 years old and 98 age and gender matched typically developing (TD) children from mainstream schools were recruited. Parenting style and sleep problems were measured via Parent Behavior Inventory (PBI) and Children s Sleep Habits Questionnaire(CSHQ), respectively. The symptom severity and intelligence level were also evaluated. Generalized linear model was used to analyze the relationship between parenting style and sleep problems. Results: There was no statistically significant difference in the parenting style of the two groups of children( P > 0.05 ); weekend sleep time of children with ASD was significantly shorter than that of the TD group [(9.1±0.7)(9.5±0.8)h, P < 0.01 ], and the score of sleep onset delay was significantly higher than that of the TD group[(1.8±0.7)(1.5±0.7), P <0.01]. However, there was no statistically significant difference in the incidence of total sleep problems and various problems between the two groups of children( P >0.05). The parental support/engagement of children with ASD was negatively associated with the total score of sleep problems( β=-2.68, 95%CI =-4.88--0.47), bedtime resistance ( β=-1.65, 95%CI =-2.54--0.77) and sleep anxiety( β=-1.01, 95%CI =-1.70--0.32). The parental hostility/coercion was positively correlated with score of daytime sleepiness( β=1.41, 95%CI =0.53-2.29)( P <0.05). Conclusion Parenting style of support/engagement is associated with lower sleep problems in children with ASD, while hostile/coercion is associated with higher sleep problems. It should be improve parental style to reduce the sleep problems in children with ASD.

Objective:To compare the efficacy of femoral neck system (FNS) and cannulated compression screw (CCS) in the treatment of femoral neck fracture in the young and middle-aged patients.Methods:A retrospective cohort study was conducted to analyze the clinical data of 91 patients with femoral neck fracture admitted to Fuzhou Second Hospital from July 2020 to December 2021, including 52 males and 39 females; aged 23-65 years [(48.9±10.3)years]. Garden classification of the fracture found that 31 patients were with type I, 9 with type II, 12 with type III and 39 with type IV. Pauwels classification of the fracture found that 7 patients were with type I, 33 with type II and 51 with type III. A total of 53 patients were treated with FNS fixation (FNS group) and 38 patients with CCS fixation (CCS group). The operation time, intraoperative blood loss, Haidukewych fracture reduction quality, hospitalization time, Barthel index, fracture healing time, and weight-bearing time were compared between the two groups. The hip function was assessed by Harris hip score in both groups at postoperative 3 months, 6 months and 1 year and at the final follow-up. The incidences of postoperative complication and secondary surgery were also compared between the two groups.Results:All the patients were followed up for 15-31 months [(22.2±5.5)months]. There were no significant differences in the operation time, Haidukewych fracture reduction quality, hospitalization time, or Barthel index (all P>0.05). The intraoperative blood loss in the FNS group was 50.0(20.0,85.0)ml, which was more than that in the CCS group [20.0(10.0,50.0)ml] ( P<0.01). The fracture healing time, partial weight-bearing time, and full weight-bearing time in the FNS group [4.0(3.0,5.0)months, 3.0(2.0,3.0)months, 5.0(4.5,6.0)months] were shorter than those in the CCS group [6.0(5.0,7.0)months, 3.0(2.8,4.0)months, 6.0(6.0,7.0)months] (all P<0.01). The Harris hip score at postoperative 3 months, 6 months and 1 year and at the final follow-up were 74.0(71.0,77.0)points, 87.0(84.0,88.5)points, 91.0(88.0,95.0)points, and 94.0(91.0,96.0)points in the FNS group, significantly higher than those in the CCS group [73.0(70.0,74.0)points, 82.5(79.8,87.0)points, 88.0(83.5,91.0)points, 89.0(84.0,93.0)points] (all P<0.05 or 0.01). There were no statistically significant differences in the incidences of postoperative complication or secondary surgery between the two groups (all P>0.05). Conclusion:Compared with CCS, FNS can shorten fracture healing time, allow patients to carry full weight as soon as possible, and significantly improve hip function in the treatment of middle-aged and young adults with femoral neck fracture, although there is more intraoperative blood loss.

Objective:To investigate the incidence of and risk factors for femoral neck shortening in young and middle-aged patients with displaced femoral neck fracture treated by a femoral neck system (FNS).Methods:A retrospective study was conducted to analyze the clinical data of 135 patients with displaced femoral neck fracture who had been treated by closed reduction and FNS internal fixation at Department of Orthopaedics, The Second Hospital of Fuzhou from December 2019 to December 2021. There were 85 males and 50 females, with an age of 51 (42, 57) years and a body mass index of 22.6 (20.9, 24.2) kg/m 2. According to the Garden classification, there were 29 cases of type Ⅲ and 106 cases of type Ⅳ. Femoral neck shortening was observed. The patients' gender, age, side of shortening, body mass index, fracture type, high-energy injury, time from injury to surgery, cortical comminution at the fracture end, reduction quality (Garden index), partial weight bearing time, complete weight bearing time, and functional evaluation (Harris score) were recorded for a univariate analysis. Multivariate logistic regression was used to analyze the influencing factors for moderate to severe shortening. Results:All the 135 patients were followed up for 17.2 (15.0, 20.2) months. Different degrees of femoral neck shortening happened in all patients, yielding an incidence of 100%(135/135). The femoral neck shortening was 4.2 (2.6, 7.7) mm in displaced femoral neck fractures fixated by FNS. The shortening continued to worsen within the first 3 months after operation, reaching a stable state in the first 6 months. Persistent shortening hardly occurred after 6 months. According to the shortening distance, the patients were divided into a mild shortening group (76 cases <5 mm) and a moderate to severe shortening group (59 cases ≥ 5 mm). The Harris score at the last follow-up in the mild shortening group (91.7 ± 2.3) was significantly higher than that in the moderate to severe shortening group (87.9 ± 3.8) ( P<0.001). The fracture healing rate was 98.7% (75/76) in the mild shortening group and 98.3% (58/59) in the moderate to severe shortening group, showing no significant difference ( P=1.000). Logistic regression analysis found that the risk factors for moderate to severe shortening were fracture type (type Ⅳ) ( OR = 10.227, 95% CI: 1.845 to 56.693, P = 0.008), cortical comminution at the fracture end (if present) ( OR=52.697, 95% CI: 9.870 to 281.352, P<0.001), and partial weight bearing time <4 weeks ( OR = 0.168, 95% CI: 0.032 to 0.893, P = 0.036). Conclusions:The incidence of femoral neck shortening may be high in young and middle-aged patients with displaced femoral neck fracture treated by FNS, leading to decreased hip function. The main risk factors for femoral neck shortening are fracture type (Garden type Ⅳ), cortical comminution at the fracture end and partial weight-bearing time less than 4 weeks.

Background Hand-arm vibration disease is harmful to human body, but there are no effective diagnosis and treatment so far, and current occupational exposure limits underestimate the health damage caused by high-frequency vibration exposure. Objective To evaluate and compare the damage to workers' peripheral circulation and peripheral nerve caused by different frequencies of vibration operation. Methods Drilling workers (n=187) from a mining company in Shandong Province and golf club head grinding workers (n=228) from a sports equipment factory in Guangdong Province were selected as study subjects. Hand symptoms were investigated. SV106 vibration meter was used to measure the target operation-associated vibration frequency spectrum. The 8 h energy-equivalent frequency weighted acceleration, cumulative vibration exposure level (CVEL), and the working age related to causing white finger in 10% of an exposed group were calculated. Result The study subjects were all male. More grinding workers reported hand symptoms than the drilling workers, e.g. peripheral circulation injury (52.6% vs 19.3%), peripheral nerve injury (71.5% vs 23.0%), hand stiffness (64.0% vs 7.0%), and deformed fingers (69.7% vs 4.3%) (all P<0.001). The main vibration frequencies of grinding operation (500-800 Hz) were much higher than those of drilling operation (125~160 Hz). CVEL and working age of vibration exposure showed a linear rising relationship with the cumulative prevalence rate of peripheral circulation and peripheral never injury, the fitting lines all showed good fitting effects (R²=0.812-0.988), and the slope of the fitting line of the grinding workers was larger than that of the drilling workers. The working age of vibration exposure associated with 10% cumulative prevalence of white finger was shorter in the grinding workers than in the drilling workers (6.81 years vs 10.27 years). According to the ISO prediction formula, the working age of vibration exposure was associated with 10% white finger prevalence shorter in the drilling workers than in the grinding workers (3.12 years vs 8.23 years). Conclusion Both the vibration exposure level and the prevalence of hand symptoms are high in two groups of workers with different vibration frequencies, and vibration exposure at a higher frequency tends to have severer damage to workers' hands.
