This study was to investigate the relationship between spring pollen distribution concentration, species and the detection results of air-borne pollen allergens in Taiyuan City, Shanxi Province during March to May 2022 and March to May 2023.A retrospective study was conducted in the Otorhinolaryngology Head and Neck Surgery Clinic of the First Hospital of Shanxi Medical University.Pollen particles will be monitored by gravity sedimentation method on the roof of the outpatient department of the First Hospital of Shanxi Medical University in downtown Taiyuan from March to May 2022-2023, and pollen species and quantity will be observed and recorded under an optical microscope.The air-borne pollen allergen detection results of all allergic rhinitis patients in the otolaryngology Head and Neck surgery Department of the First Hospital of Shanxi Medical University were extracted from the relevant outpatient system. SPSS software and Pearson correlation analysis were used to compare the correlation between the allergens and the dominant air-borne pollen monitoring results. Results are as follows: (1)A total of 18 species of spring pollen in Taiyuan City were monitored in 2022-2023, with 101 177.5 grains, and the dominant airborne pollen was poplar (16.69%) and pine (29.06%) pollen. The pollen of poplar (11.96%), elm (7.89%) and cypress (8.68%) were dominant in early spring; Pine (25.16%) pollen predominated in late spring. The two peaks of pollen dispersal in Taiyuan were in late March (15 479 grains) and early and mid May (15 094/15 343 grains).(2) The positive rates of allergens in serum specific IgE detection were: wormwood (46%, 248/541 cases), tree combination (26%, 143/541 cases), ragweed (19%, 101/541 cases), humulus scandens (9%, 49/541 cases).(3)There was a linear positive correlation between the positive rate of air-borne pollen allergens in allergic rhinitis patients in the Department of Otolaryngology Head and Neck Surgery in the First Hospital of Shanxi Medical University and the dominant air-borne pollen concentration in the same period ( P<0.05, r=0.999). In conclusion, two spring pollen dispersal peaks were formed in late March and early to mid May in Taiyuan City, and the dominant air-borne pollens were poplar and pine pollens. The positive rate of air borne pollen allergen sIgE showed that wormwood allergy was the highest.There was a positive correlation between the concentration of air-borne pollen and the positive rate of air-borne pollen allergens in patients with allergic rhinitis in the Department of otorhinolaryngology and head and neck surgery in Taiyuan in 2022 and 2023.The monitoring of pollen distribution in spring can provide an important scientific basis for clinical workers to formulate prevention and treatment plans for patients with allergic rhinitis in the season, and provide data reference for the epidemiological investigation of allergic diseases in Taiyuan in the future.

Robot-assisted fracture reduction usually involves fixing the proximal end of the fracture and driving the distal end of the fracture to the proximal end in a planned reduction path. In order to improve the accuracy and safety of reduction surgery, it is necessary to know the changing rule of muscle force and reduction force during reduction. Fracture reduction force was analyzed based on the muscle force of femoral. In this paper, a femoral skeletal muscle model named as PA-MTM was presented based on the four elements of skeletal muscle model. With this, pinnate angle of the skeletal muscle was considered, which had an effect on muscle force properties. Here, the muscle force of skeletal muscles in different muscle models was compared and analyzed. The muscle force and the change of the reduction force under different reduction paths were compared and simulated. The results showed that the greater the pinnate angle was, the greater the influence of muscle strength was. The biceps femoris short head played a major role in the femoral fracture reduction; the force in the

Objective:To investigate the relationship between plasma Golgi protein 73 (GP73) levels and the occurrence and development of non-alcoholic fatty liver disease (NAFLD), and to establish a diagnostic model based on this combination with lipid metabolism indicators to clarify its diagnostic efficacy and clinical application value for NAFLD.Methods:225 cases with NAFLD [diagnosed by ultrasound, transient elastography (FibroScan502) and liver biopsy (some patients)] and 108 healthy controls were selected from the Department of Hepatology and Physical Examination Center of Integrated Traditional Chinese and Western Medicine, The Third Hospital of Hebei Medical University. Clinical data, routine peripheral blood and serum biochemical test results were collected. The plasma GP73 level was detected by enzyme-linked immunosorbent assay. SPSS 21.0 statistical software was used for statistical analysis. Binary logistic regression model was used to calculate the NAFLD diagnostic model. Receiver operating characteristic curve was used to evaluate the NAFLD constructed model diagnostic efficacy.Results:NAFLD incidence was significantly reduced in younger age group, mostly in young and middle-aged male. However, the NAFLD incidence was increased with increasing age in female. The analysis of age ratio composition showed that the average age for NAFLD onset was 20 ~ 50 years old, and the incidence rate was as high as 47% in among 30 ~ 39 years old, but the incidence rate was significantly decreased in over 60 years old (4.00%). GP73 was an independent risk factor for the occurrence and development of NAFLD. The diagnostic models of GBT, GB and GT were established by GP73 (G) combined with body mass index (BMI, B) and serum triglyceride (TG, T), and the results showed that the areas under the curves of GBT, GB and GT models were 0.969, 0.937 and 0.909, respectively. The sensitivity and the specificity were 84.90%, 77.80% and 84.00%, and 95.40%, 95.40% and 82.40%, respectively, P < 0.05. The GBT model had efficacy of best diagnostic performance. Conclusion:NAFLD is more common in young and middle-aged male, but with advanced age, the incidence of female patients gradually increases. Plasma GP73 levels are related to the occurrence and development of NAFLD. The GBT model can be used as a new model for non-invasive diagnosis and one of the indicators for clinical evaluation of diagnostic efficacy of NAFLD.

Objective: To explore the clinical value of plasma heme oxygenase 1(HO-1) in the development of non-alcoholic fatty liver disease(NAFLD). Methods: Patients with NAFLD were selected from the Physical examination center and the Department of Traditional and Western Medical Hepatology of Third Hospital of Hebei Medical University. A combination of ultrasound and liver elastography was used to screen NAFLD patients and healthy persons. General clinical characteristics, peripheral blood cell count and liver biochemical test results were collected synchronously, plasma samples were retained, and plasma HO-1 level was detected by enzyme-linked immunosorbent assay. SPSS21.0 statistical software was used for statistical analysis, multivariate logistic regression analyses was used to analyse the independent risk factors affecting the incidence and progression of NAFLD. The diagnostic efficacy of indicators related to development of NAFLD was assessed by the receiver operating characteristic curve(ROC). Results: A total of 328 patients with NAFLD and 113 healthy controls were included. According to the liver biochemical results, the NAFLD group was divided into 148 patients with normal liver enzymes and 180 patients with abnormal liver enzymes. The level of HO-1 in the three groups was 9.09 ± 2.19, 14.38 ± 2.63, 17.00 ± 3.30 ng/ml, and was increased respectively of healthy controls, patients with normal liver enzymes and patients with abnormal liver enzymes. Analyzing plasma HO-1 levels of components associated with metabolic disorders suggests that components without metabolic syndrome(9.83 ± 3.21) < components with 1 metabolic syndrome(13.59 ± 3.72) < components with 2 or more metabolic syndrome(16.09 ± 3.41), P < 0.001. The results of HO-1 level stratification analysis showed that WBC, ALT, AST, GGT, TG increased as HO-1 level increased, and the pairwise difference was statistically significant (P < 0.001). The WBC count of NAFLD is significantly higher than healthy group(6.79 ± 1.62 vs 5.68 ± 1.36, P < 0.001). The univariate and multivariate regression analyses of all the subjects showed that HO-1, TG and BMI were prognostic factors for the occurrence of NAFLD and HO-1, TC, GLU were prognostic factors for the progression of NAFLD, P < 0.05. The ROC analysis showed that HO-1 was reliable markers for predicting the occurrence and progression of NALFD, the sensitivity and specificity were respectively 85.10%, 92.90% and 38.33%, 95.27%. Conclusion Plasma HO-1 can predict the occurrence and progression of NAFLD and is expected to be a novel molecular diagnostic marker for NAFLD and NASH.

Objective To summarize the preliminary clinical outcomes of combination therapy with molecular targeted agents/immunological agents and to explore the potential value of multidisciplinary therapy in the treatment of postoperative refractory recurrent hepatobiliary tumor.Methods 52 cases of postoperative refractory recurrent hepatobiliary tumor during June 2016 to January 2019 from outpatient and inpatient departments at the First Medical Center of PLA General Hospital were prospectively collected,including 37 males and 15 females,with a mean age of (56.2 ± 8.5) years.Referring to the results of next-generation sequencing (NGS) and other-omics,we designed individualized therapy options for each patient.Follow-ups were done regularly and tumor responses were assessed by modified response evaluation criteria in solid tumors (mRECIST).Results Of 52 patients,median follow-up was 10 months (range 3-31 months).14 (26.9％) patients achieved a complete response (CR).8 (15.3％) patients achieved a partial response (PR).14 (26.9％) patients had stable disease (SD).16 (30.8％,including 4 deaths) had progressive disease (PD).Objective response rate and disease control rate were 42.3％ (22/52) and 69.2％ (36/52),respectively.The median progression-free survival (PFS) was 7 months.6-and 12-month overall survival rates were 100％ (48/48),87.5％ (21/24),respectively.Conclusions Precision medicine has good guidance on the treatment of refractory recurrence of hepatobiliary tumors.The combination therapy of multi-target tyrosine kinase inhibitors and immune checkpoint inhibitors may achieve better disease control and deserve further promotion in clinical application.

Objective To study the effect of extended hepatectomy for hilar cholangiocarcinoma (HCCA) of the Bismuth-Corlette type Ⅲ and Ⅳ.Methods The clinical data of 73 patients with HCCA of the Bismuth-Corlette type Ⅲ and Ⅳ treated in our department from January,2008 to June,2016 were analyzed retrospectively.The extended hepatectomy group of patients consisted of 29 patients who underwent hepatectomy with half or more than half of the liver removed or/and combined with hepatic caudate lobectomy.The limited hepatectomy group consisted of 44 patients who underwent non-anatomical hepatectomy around the hepatic hilar region.Results Compared with the limited hepatectomy group,patients in the extended hepatectomy group had significantly longer operations with significantly more intraoperative blood loss.However,the complication rate was significantly lower than that of the limited hepatectomy group.There was no perioperative death in the extended hepatectomy group,while 3 perioperative deaths occurred in the limited hepatectomy group.The R0 resection rate was 93.1％ (27 of 29) for the extended hepatectomy group,while it was 54.6％ (24 of 44) for the limited hepatectomy group (P＜0.05).The 1-,3-and 5-year survival rates or the extended hepatectomy group were 81.4％,51.4％ and 19.3％,respectively while the corresponding rates for the limited hepatectomy group were 70.5％,24.4％ and 8.7％,respectively (P＜0.05).Conclusions After adequate preoperative radiological assessments on tumor resectability,and the residual liver volumes,with preoperative biliary drainage to improve liver function,extended hepatectomy effectively increased R0 resection and survival rates with improved prognosis for patients with HCCA of Bismuth-Corlette type Ⅲ and Ⅳ.

Allergic rhinitis (AR) is a global health problem that causes major illnesses and disabilities worldwide. Epidemiologic studies have demonstrated that the prevalence of AR has increased progressively over the last few decades in more developed countries and currently affects up to 40% of the population worldwide. Likewise, a rising trend of AR has also been observed over the last 2–3 decades in developing countries including China, with the prevalence of AR varying widely in these countries. A survey of self-reported AR over a 6-year period in the general Chinese adult population reported that the standardized prevalence of adult AR increased from 11.1% in 2005 to 17.6% in 2011. An increasing number of original articles and imporclinical trials on the epidemiology, pathophysiologic mechanisms, diagnosis, management and comorbidities of AR in Chinese subjects have been published in international peer-reviewed journals over the past 2 decades, and substantially added to our understanding of this disease as a global problem. Although guidelines for the diagnosis and treatment of AR in Chinese subjects have also been published, they have not been translated into English and therefore not generally accessible for reference to non-Chinese speaking international medical communities. Moreover, methods for the diagnosis and treatment of AR in China have not been standardized entirely and some patients are still treated according to regional preferences. Thus, the present guidelines have been developed by the Chinese Society of Allergy to be accessible to both national and international medical communities involved in the management of AR patients. These guidelines have been prepared in line with existing international guidelines to provide evidence-based recommendations for the diagnosis and management of AR in China.
