ObjectiveTo evaluate the efficiency and safety of № I Empirical Prescription for Chronic Prostatitis (№ I EPCP) in the treatment of type Ⅲ refractory chronic prostatitis.

METHODSWe randomly assigned 53 cases of type Ⅲ refractory chronic prostatitis with damp-heat and blood stasis to an experimental and a control group to receive № I EPCP at 1 dose per day and saw palmetto extract at 160 mg bid), respectively, all for 8 weeks. Before and after 4 and 8 weeks of treatment, we obtained The National Institute of Health Chronic Prostatitis Symptom Index (NIH-CPSI) scores, Traditional Chinese Medicine Syndrome Scores (TCMSS), maximum urinary flow rate (Qmax), average urinary flow rate (Qavg), Hamilton Depression Rating Scale (HAMD) scores and Hamilton Anxiety Rating Scale (HAMA) scores, and compared them between the two groups of patients.

RESULTSTotally 48 of the patients completed the medication and follow-up, 25 in the experimental and 23 in the control group. Compared with the baseline, the NIH-CPSI scores after 8 weeks of treatment were significantly decreased in the experimental (27.82 ± 7.25 vs 15.46 ± 4.77, P <0.05) and the control group (25.98 ± 6.47 vs 21.06 ± 5.74, P <0.05), and so were the TCMSSs (24.64 ± 9.82 vs 16.42 ± 6.33 and 9.15 ± 3.74, P <0.05, and 23.67 ± 8.73 vs 18.55 ± 5.92 and 13.48 ± 4.45, P <0.05); the Qmax at 8 weeks were dramatically increased in the experimental group (［18.45 ± 7.81］ vs ［23.44 ± 8.73］ ml/s, P <0.05) and the control (［17.58 ± 6.92］ vs ［21.26 ± 8.32］ ml/s, P <0.05), and so was the Qavg (［11.27 ± 5.33］ vs ［16.51 ± 7.36］ ml/s, P <0.05 and ［10.66 ± 5.82］ vs ［13.44 ± 6.16］ ml/s, P <0.05); the HAMD scores were remarkably reduced in the experimental group (22.74 ± 6.37 vs 17.62 ± 5.71 and 12.54 ± 5.22, P <0.05) and the control (23.55 ± 7.14 vs 22.34 ± 6.88 and 21.62 ± 5.63, P <0.05), and so were the HAMA scores (21.37 ± 7.15 vs 18.42 ± 6.35 and 14.63 ± 7.11, P <0.05 and 20.54 ± 6.77 vs 19.87 ± 6.24 and 19.42 ± 7.04, P <0.05). No obvious adverse reactions were observed in either of the two groups during the medication.

CONCLUSIONS№ I EPCP deserves promotion and clinical application for its definite effectiveness and safety in the treatment of type Ⅲ refractory chronic prostatitis with damp-heat and blood stasis.

Photoimmunotherapy (PIT) is an emerging tumor-targeted phototherapy that combines the tumor specificity of monoclonal antibodies with the phototoxicity of light absorbers to rapidly and selectively induce the immunogenic death of target tumor cells. PIT has minimal side effects due to its high specificity. The immunogenic cell death induced by PIT results in rapid maturation of immature dendritic cells proximal to dying tumor cells. Subsequently, the mature dendritic cells present the tumor antigens to CD8+ T cells and induce their activation and proliferation, thus enhancing the antitumor immune response of the host. PIT can also improve the anticancer efficacy by enhancing the penetration of nanomedicines into tumor tissues. In view of the excellent application prospects of PIT, this review summarizes the advances in the immune activation mechanism of PIT, the superenhanced permeability and retention effect, and the new strategies for combinatory therapy, providing references for future research and clinical translation.

BACKGROUND: Lung cancer is currently the leading malignant tumor in both domestic and foreign morbidity and mortality. Surgical treatment is the main treatment option for lung cancer. The aim of this study is to explore the effects of enhanced recovery after surgery (ERAS) combined with respiratory function exercise combined with single-hole thoracoscopic surgery on lung cancer patients with postoperative pulmonary complications, postoperative pain, time to get out of bed, time to extubation and length of hospital stay. METHODS: A total of 240 patients who underwent endoscopic lung cancer surgery at the Affiliated Hospital of Yangzhou University and the Yancheng First People's Hospital from October 2017 to October 2019 were randomly divided into 4 groups, with 60 patients in each group. Patients in group A underwent single-hole thoracoscopic surgery, and preoperatively performed ERAS concept education and respiratory function training; group B used conventional 3-hole thoracoscopic surgery, and performed ERAS concept education and respiratory function training before operation; group C used conventional 3-hole thoracoscopic operation surgery, routine hospitalization education and nursing guidance, routine respiratory function training, no preoperative ERAS concept education; group D used single-hole thoracoscopic surgery, routine hospitalization education and nursing guidance, routine respiratory function training, no preoperative ERAS concept mission. The number of postoperative pulmonary complications, postoperative pain, time to get out of bed, extubation time, and hospital stay were recorded in the four groups. RESULTS: Compared with the groups B, C, and D, the incidence of pulmonary complications was significantly reduced, and the time to get out of bed, extubation time, and hospital stay were significantly shortened in group A. Compared with groups B, C, the postoperative pain was significantly reduced in group A. Compared with group C, the pulmonary complications were significantly reduced, and the time to get out of bed, extubation time and hospital stay were significantly shortened in group B. The differences were statistically significant (P<0.05). There was no significant difference in postoperative pain between group A and group D, group B and group C (P>0.05). CONCLUSIONS For patients with single-hole thoracoscopic lung cancer surgery, the ERAS concept guidance can effectively reduce the incidence of pulmonary complications and postoperative pain, shorten the time to get out of bed, the time to extubate, and the length of hospital stay.

BACKGROUNDThe dust mites, which are mostly represented by Dermatophagoides spp. (Acari: Pyroglyphidae), are the major sources of indoor allergens. Identification and characterization of these mite allergen molecules are an important step in the development of new effective diagnostic procedures and possible therapeutic strategies for allergic disorders associated with dust mites.

METHODSTotal RNA was extracted from Dermatophagoides farinae. The gene coding for Der f 3 was amplified by RT-PCR with the primers designed based on previous sequence published in GenBank. The target gene was cloned intermediately into pMD19-T plasmid and finally into plasmid pET28a (+), expressed in E. coli BL21 at the aid of the inducer isopropyl-D-thiogalactopyranoside (IPTG). The physicochemical properties, spatial structure of the allergen were analyzed with bioinformatics software.

RESULTSThe cDNA coding for group 3 allergen of Dermatophagoides farinae from China was cloned and expressed successfully. Sequencing analysis showed that there were nineteen mismatched nucleotides in five Der f 3 cDNA clones in comparison with the reference (GenBank Accession No. AY283291), which resulted in deduced amino acid sequence incompatibility in eleven residues. Bioinformatics analysis revealed that the Der f 3 pro-protein was an extracellular hydrophobic protein, consisting of 259 amino acids with a 16 amino acid signal peptide. The protein was deduced to have three chymotrypsin active sites (53-68 AA, 108-122 AA and 205-217 AA), one N-glycosylation site, one cAMP- and cGMP-dependent protein kinase phosphorylation site, four protein kinase C phosphorylation sites, two casein kinase II phosphorylation sites, and five N-myristoylation sites.

CONCLUSIONSDer f 3 is an extracellular hydrophobic protein which possesses multiple activation and phosphorylation sites. Polymorphism may exist in the Der f 3 gene but this needs to be further confirmed in the future.

Objective To analyze the genetic characteristics of the hemagglutinin （HA) and neuraminidase （NA) genes of influenza B viruses isolated in Yancheng City from 2015 to 2017. Methods The throat swab specimens of influenza-like illness( ILI) from sentinel surveillance hospital and outbreak sites were collected and sent to Yancheng CDC for virus nucleic acids and virus isolation testing. After validation with serological tests, eighteen strains of influenza B virus isolates were selected to amplify their HA1 and NA genes through RT-PCR assay. Their molecular characteristics of the obtained viral HA1 and NA gene sequences were analyzed using bioinformation software from three aspects, including nucleic acid level, amino acid level and molecular evolution level. Results Basically, the clustering relationships and the branche patterns between HA1 and NA genes from the 18 Yancheng influenza B virus strains were similar. The Yamagata lineage strains in 2015 were distributed in the Yamagata Clade 3 branch, belonging to Phuket/3073 strains. The Victoria lineage strains in 2016-2017 were distributed in the Victoria Clade 1A branch, belonging to Brisbane/60 strains. D196N substitution was detected on HA1 protein in all of Yamagata lineage strains at 190-helix epitope; Amino acid substitutions of victoria lineage strains involved two antigenic epitopes, 117 and 129 sites of 120-loop epitope and 197 and 199 sites of 190-helix epitope. No Intra-lineage or inter-lineage rearrangements occurred in Yancheng strains. Eighteen influenza B strains had no mutations in catalytic residues and drug resistant sites of NA genes. Conclusion The Yamagata strains well matched with vaccine strain B/Phuket/3073/2013. The HA1 and NA genes of victoria lineage strains circulated in Yancheng City during 2016 to 2017 are changing gradually. The accumulation of these mutations will result in antigenic drift of victoria lineage strains and increase the mismatch of the IFV field stains with the available vaccine strains, which may reduce the protective effect of flu vaccine.

Objective:To understand the current situation of male nurses in Dalian area and explore its future development direction.Methods:From August to September in 2020, 189 male nurses who had been engaged in clinical nursing for more than one year in 29 hospitals in Dalian were selected by convenient sampling method, and they were investigated by questionnaire. SPSS 25.0 software was used for statistical analysis. The counting data were described by rate or constituent ratio. Logistic regression analysis was used to analyze the important factors influencing male nurses′ willingness to change profession.Results:A total of 189 male nurses were investigated, 137 of them were under 30 years old, accounting for 72.5%. They had high education background and low professional title, mainly concentrated in ICU, operation room and emergency department of public owned 3A or 3B hospitals, with a monthly income of 3 000 to 8 000 yuan. 33 nurses(17.5%) chose nursing profession because they couldn′t change careers by profession adjustment. 135 nurses (71.4%) considered that work pressure was high. 70 nurses (37.0%) had the idea of changing careers. The main influencing factors included:nursing career was not in accordance with individual interest, dislike of female boss, low income. The prominent problem in nursing career was "inconvenience in gender""the confusion of self-positioning".Conclusions:The hospital should improve the income of male nurses, reduce the work pressure, establish magnetic hospital, establish career planning for them, and expand the team of male nurses. Male nurses should take the initiative to improve their professional ability and professional title, so as to provide necessary conditions for the realization of nursing managers, educators, researchers and other professional goals.

BACKGROUND:Achilles tendon adhesion after Achilles tendon injury can lead to decreased biomechanical properties,weakened healing ability,and ultrastructural changes of Achilles tendon,which further affects patients'daily life and work ability.Therefore,how to effectively deal with and prevent Achilles tendon adhesion has become a hot and difficult problem in clinical treatment. OBJECTIVE:To analyze the effects of biological amniotic membranes on postoperative Achilles tendon adhesion,biomechanics,and ultrastructural changes in rats with Achilles tendon rupture. METHODS:Sixty 6-week-old SD rats were selected to establish bilateral Achilles tendon rupture models and divided into two groups(n=30 per group)by the random number table method.In the model group,the severed end of the tendon was sutured directly.In the amniotic membrane group,the biological amniotic membrane was wrapped around the broken anastomosis and fixed by a suture.The adhesion,biomechanics,morphology,and structure of the Achilles tendon and the expression of p38 and ERK1/2 protein were evaluated 1,2,and 4 weeks after surgery. RESULTS AND CONCLUSION:(1)1 week after operation,the Achilles tendon and peritendinous tissues of the two groups were mildly edema,and the adhesion of the Achilles tendon tissues in the model group was more obvious.2 weeks after the intervention,the Achilles tendon and peritendinous tissues of the model group still had edema,and the adhesion degree between the Achilles tendon and the surrounding tissues was heavier than that of the amniotic membrane group.4 weeks after operation,there was no edema around the Achilles tendon in both groups,and the healing was well.The adhesion degree of the Achilles tendon in the amniotic membrane group was less than that in the model group.The maximum tension of Achilles tendons in the amniotic membrane group was higher than that in the model group at 2 and 4 weeks after operation(P<0.001).(2)Hematoxylin-eosin staining and transmission electron microscopy revealed that 1 week after operation,the tendon structure of rats of the two groups was disordered and the collagen fibers were sparsely arranged,in which the model group demonstrated obvious inflammatory reaction and adhesion to the Achilles tendon.Two weeks after operation,the model group still demonstrated obvious inflammatory response,adhesion of Achilles tendon,and irregular ordering of collagen fibers.The amniotic membrane group exhibited an orderly arrangement of collagen fibers and expansion of the endoplasmic reticulum of fibroblasts.At 4 weeks after operation,the collagen fibers of the Achilles tendon in the model group were thickened and disordered,and the rough endoplasmic reticulum was less in the fibroblasts,while the collagen fibers in the amniotic membrane group were ordered and thin,and the fibroblasts contained a large number of rough endoplasmic reticulum.(3)Four weeks after operation,western blot assay exhibited that the expressions of p38 and ERK1/2 protein in the Achilles tendon tissue of rats in the amniotic membrane group were lower than those in the model group(P<0.05).(4)The results confirm that the biologic amniotic membrane can promote the healing and inhibit the adhesion of Achilles tendon after the operation of the ruptured Achilles tendon,which may be associated with the regulation of the MAPK/ERK signaling pathway.

Objective: To explore the prognostic factors of extracellular NK/T cell lymphoma (ENKTL) treated with pegaspargase/L-asparaginase. Methods: The clinical data of 656 ENKTL patients diagnosed at 11 medical centers in the Huaihai Lymphoma Working Group from March 2014 to April 2021 were retrospectively analyzed. The patients were randomly divided into two groups: a training set (460 cases) and a validation set (196 cases) at 7∶3, and the prognostic factors of the patients were analyzed. A prognostic scoring system was established, and the predictive performance of different models was compared. Results: Patients' median age was 46 (34, 57) years, with 456 males (69.5% ) and 561 nasal involvement (85.5% ). 203 patients (30.9% ) received a chemotherapy regimen based on L-asparaginase combined with anthracyclines, and the 5-year overall survival rate of patients treated with P-GEMOX regimen (pegaspargase+gemcitabine+oxaliplatin) was better than those treated with SMILE regimen (methotrexate+dexamethasone+cyclophosphamide+L-asparaginase+etoposide) (85.9% vs 63.8% ; P=0.004). The results of multivariate analysis showed that gender, CA stage, the Eastern Cooperative Oncology Group performance status (ECOG PS) score, HGB, and EB virus DNA were independent influencing factors for the prognosis of ENKTL patients (P<0.05). In this study, the predictive performance of the prognostic factors is superior to the international prognostic index, Korean prognostic index, and prognostic index of natural killer lymphoma. Conclusion: Gender, CA stage, ECOG PS score, HGB, and EB virus DNA are prognostic factors for ENKTL patients treated with pegaspargase/L-asparaginase.

Objective: To analyze and compare the distribution of the high-risk population of upper gastrointestinal (UGI) cancer and the factors influencing the compliance rate of endoscopic screening in urban China and rural China. Methods: From 2015 to 2017, an epidemiological survey was conducted on residents aged 40-69 in two rural areas (Luoshan county of Henan province, Sheyang county of Jiangsu province) and two urban areas (Changsha city of Hunan province, Harbin city of Heilongjiang province). As a result, high-risk individuals were recommended for endoscopic screening. Chi-square χ(2) test was used to compare the high-risk rate of UGI cancer between urban and rural residents. In addition, the multivariate logistic regression model was used to analyze the factors influencing the compliance rate of endoscopic screening. Results: A total of 48, 310 residents aged 40-69 were enrolled in this study, including 22 870 (47.34%) residents from rural areas and 25 440 (52.66%) residents from urban areas. A total of 23 532 individuals were assessed with a high risk of UGI cancer, with an overall risk rate of 48.71%. A higher proportion of participants with high risk was observed in rural China (56.17%, 12 845/22 870) than in urban China (42.01%, 10 687/25 440). A total of 10 971 high-risk individuals with UGI cancer participated in endoscopic screening, with an overall compliance rate of 46.62% (10 971/23 532), 45.15% (5 799/12 845) in rural China, and 48.40% (5 172/10 687) in urban China. In rural population, the compliance rate of endoscopic screening was higher in those of females, aged 50-69 years, primary school education or above, high income, a family history of UGI cancer, history of gastric and duodenal ulcer, history of reflux esophagitis, and history of superficial gastritis, but lower in smokers (P<0.05). Among the urban population, the compliance rate of endoscopic screening was higher in those aged 40-49 years, uneducated, low income, family history of UGI cancer, history of reflux esophagitis, history of superficial gastritis, but lower in smokers (P<0.05). Conclusions: The proportion of participants with high risk of UGI cancer in rural areas is higher than that of urban areas. The compliance rates of endoscopic screening in urban and rural areas are low, and influencing factors of endoscopic screening exhibit some differences in rural China and urban China.

Objective To evaluate the actual effect of the schistosomiasis control program in Jiangsu Province from 2010 to 2015. Methods A total of 67 schistosomiasis-endemic counties in 10 cities were selected, and a combination of retrospective investigation and on-site investigation was adopted to collect and record the epidemic data of the counties from 2010 to 2015, and a retrospective survey database of epidemic situation was established. The effects of integrated control strategies with both Oncomelania hupensis snail control and infection source control were evaluated. Results From 2010 to 2015, 2 465 911 persons who lived in endemic areas were detected for schistosomiasis, with 16 974 positive cases of blood examinations, and 8 positive cases of fecal examinations. Totally 5 145 people with advanced schistosomiasis were treated and 40 460 people with the history of schistosome cercarial-infested water contact received the expanded chemotherapy. A total of 127 636 cattle raised in the endemic areas were detected, and 51 619 cattle (head-times) with the history of cercarial-infested water contact also received the expanded chemotherapy. The area with snails control by molluscicides was 18 604.84 hm². By the end of 2015, schistosomeinfected snails had not been found and there was no zoological schistosome infection for 5 consecutive years, and in addition, there had been no acute schistosome-infected persons for 6 consecutive years in the whole province. The area with snails dropped to 1 977.18 hm², with a decreasing rate of 55.24% compared with that in 2010. Conclusion After the implementation of the plan for the prevention and control of schistosomiasis in Jiangsu Province (2010–2015), the prevention and control of schistosomiasis has achieved remarkable effects and realized the goal of the plan.
