Objective:To explore the efforts of applying mindfulness stress reduction therapy in alleviating stress reactions and burnout among head nurses in the context of the Coronavirus disease 2019 (COVID-19).Methods:This was a quasi experimental study. In June 2021, 109 head nurses with mild or above burnout measured by Maslach Burnout Inventory (MBI) from 12 hospitals in Zhangjiagang City were selected as the research objects to implement mindfulness-based stress reduction therapy for 8 weeks, and the scores of the Five Facet Mindfulness Question-naire (FFMQ), Stress Response Questionnaire (SRQ) and MBI of the head nurses were compared before and after the intervention.Results:The five dimensions of observation, description, perceived action, non-judgment, and non-response and the total scores of the FFMQ were (26.28 ± 1.32), (26.94 ± 1.29), (25.49 ± 0.99), (25.45 ± 1.05), (23.48 ± 1.01), and (127.63 ± 3.78) of the post-intervention, which were higher than the pre-intervention scores of (25.04 ± 1.37), (25.04 ± 1.37), (25.37 ± 1.18), (24.15 ± 1.00), (24.09 ± 0.98), (22.26 ± 1.04), and (120.90 ± 4.06), with statistically significant differences ( t values were -39.21- -15.36, all P<0.01). The three dimensions of emotional, somatic, and behavioral responses and total scores of the post-intervention SRQ were (27.70 ± 6.12), (20.75 ± 4.20), (15.19 ± 3.11), and (65.99 ± 12.43), respectively, lower than the pre-intervention scores of (29.19 ± 6.91), (21.86 ± 5.20), (16.48 ± 4.16), and (70.12 ± 15.97), with statistically significant differences ( t values were 5.70-9.33, all P<0.01); the scores of dimensions of emotional exhaustion and depersonalization in post-intervention MBI were (26.24 ± 4.60) and (5.96 ± 1.25), lower than the pre-intervention scores of (29.66 ± 6.02) and (6.90 ± 1.59). The post-intervention scores of personal fulfillment (32.37 ± 5.02), higher than the pre-intervention scores of (28.60 ± 6.04), all with statistically significant differences ( t=15.36, 13.50, -9.65, all P<0.01). Conclusions:The implementation of mindfulness stress reduction therapy for the head nurses can relieve their work pressure due to the prevention and control of the COVID-19 epidemic, reshape their healthy psychology, and reduce job burnout.

Clinicopathological features and prognosis of SMARCA4-deficient non-small cell lung carcinoma: an analysis of 127 cases / 中华病理学杂志

Objective: To investigate and elucidate the clinicopathological and prognostic characteristics of SMARCA4-deficient non-small cell lung cancer. Methods: The clinicopathological and prognostic data were collected in 127 patients with SMARCA4-deficient non-small cell lung cancer diagnosed in Shanghai Pulmonary Hospital, Shanghai, China from January 2020 to March 2022. The variation and expression of biomarkers related to treatment were retrospectively reviewed. Results: One hundred and twenty-seven patients were eligible for enrollment. Among them 120 patients (94.5%) were male and 7 cases (5.5%) were female, while the average age was 63 years (range 42-80 years). There were 41 cases (32.3%) of stage Ⅰ cancer, 23 cases (18.1%) of stage Ⅱ, 31 cases (24.4%) of stage Ⅲ and 32 cases (25.2%) of stage Ⅳ. SMARCA4 expression detected by immunohistochemistry was completely absent in 117 cases (92.1%) and partially absent in 10 cases (7.9%). PD-L1 immunohistochemical analyses were performed on 107 cases. PD-L1 was negative, weakly positive and strongly positive in 49.5% (53/107), 26.2% (28/107) and 24.3% (26/107) of the cases, respectively. Twenty-one cases showed gene alterations (21/104, 20.2%). The KRAS gene alternation (n=10) was most common. Mutant-type SMARCA4-deficient non-small cell lung cancer was more commonly detected in females, and was associated with positive lymph nodes and advanced clinical stage (P<0.01). Univariate survival analysis showed that advanced clinical stage was a poor prognosis factor, and vascular invasion was a poor predictor of progression-free survival in patients with surgical resection. Conclusions: SMARCA4-deficient non-small cell lung cancer is a rare tumor with poor prognosis, and often occurs in elderly male patients. However, SMARCA4-deficient non-small cell lung cancers with gene mutations are often seen in female patients. Vascular invasion is a prognostic factor for disease progression or recurrence in patients with resectable tumor. Early detection and access to treatment are important for improving patient survivals.

Pulmonary granular cell tumors: a clinicopathological analysis of five cases / 中华病理学杂志

Objective: To investigate the clinicopathological features of pulmonary granular cell tumors (pGCTs) and to improve the diagnostic accuracy of the tumor. Methods: A total of 5 pGCTs were diagnosed from February 2016 to January 2022 at Shanghai Pulmonary Hospital, Tongji University School of Medicine and Fudan University Shanghai Cancer Center, China. Immunohistochemical staining, and analysis of the clinicopathological characteristics were performed. Results: The average age of the pGCTs patients was 46 years (ranging from 24 to 54 years), with 3 females and 2 males. One case occurred in the bronchus with multiple nodules in the lung, 2 cases occurred in the bronchial opening, and 2 cases were solitary nodules in the lung. The maximum diameter of the tumors ranged from 12 to 15 mm (mean size 14 mm). Microscopically, the tumor showed infiltrative growth and consisted of round, oval or polygonal cells. Abundant eosinophilic cytoplasm was noted, and the nucleoli were prominent. None of the 5 cases showed any mitosis or necrosis. Immunohistochemical and histochemical study showed positive staining for S-100 (5/5), SOX10 (5/5), Vimentin (5/5), TFE3 (4/5), PAS (3/5), and amylase-digested-PAS (3/5), while 4 cases were negative for CD68. TFE3 FISH analyses on 2 cases showed that no signal abnormality was detected in these 2 cases. The average proliferation index of Ki-67 was 2.2% (range 0-5%). There was no recurrence in 4 cases of pGCTs with a follow-up time ranging from 2 months to 60 months. Conclusions: pGCTs are very rare tumors, most likely originating from Schwann cells. Immunohistochemical staining is the conventional diagnostic tool for pGCTs diagnosis. Recognition of this entity is essential for pathologists to avoid misdiagnosis and unnecessary treatments.

Application of the WHO Classification of Thoracic Tumors (2021) grading system in invasive pulmonary adenocarcinoma and its correlation with the targeted genes' variations / 中华病理学杂志

Objective: To investigate the applicability of the 2021 WHO classification of thoracic tumors' new grading system for invasive pulmonary adenocarcinoma (IPA) with different clinical stages and its correlation with the characteristics of targeted genes' variation. Methods: A total of 2 467 patients with surgically resected primary IPA in Shanghai Pulmonary Hospital, Shanghai, China from September to December 2020 were retrospectively analyzed. Eligible cases were graded using the new grading system of IPA of the 2021 WHO classification of thoracic tumors. The clinicopathological data and targeted-gene abnormality were collected. The utility of new grading system of IPA in different clinical stages was investigated. The correlation of clinicopathological features and targeted-gene abnormality in different grades of IPA were compared. Results: All 2 311 cases of IPA were included. There were 2 046 cases of stage Ⅰ IPA (88.5%), 169 cases of stage Ⅱ (7.3%), and 96 cases of stage Ⅲ (4.2%). According to the new classification system of IPA, 186 cases (9.1%), 1 413 cases (69.1%) and 447 cases (21.8%) of stage-Ⅰ adenocarcinoma were classified as Grade 1, Grade 2 and Grade 3, respectively. However, there were no Grade 1 adenocarcinomas in stages Ⅱ and Ⅲ cases. Among stage-Ⅱ and Ⅲ IPA cases, there were 38 Grade 2 cases (22.5%) and 131 Grade 3 cases (77.5%), and 3 Grade 2 cases (3.1%) and 93 Grade 3 cases (96.9%), respectively. In stage-Ⅰ cases, no tumor cells spreading through airspace (STAS), vascular invasion or pleural invasion was found in Grade 1 of IPA, while the positive rates of STAS in Grade 2 and 3 IPA cases were 11.3% (159/1 413) and 73.2% (327/447), respectively. There was a significant difference among the three grades (P<0.01). Similarly, the rates of vascular and pleural invasion in Grade 3 IPA cases were 21.3% (95/447) and 75.8% (339/447), respectively, which were significantly higher than those of 1.3% (19/1 413) and 3.0% (42/1 413) in Grade 2 (P<0.01). EGFR mutational rates in Grades 1, 2 and 3 IPA were 65.7% (94/143), 76.4% (984/1 288) and 51.3% (216/421), respectively. The differences among the three grades were statistically significant (P<0.01). No fusion genes were detected in Grade 1 IPA, while the positive rates of ROS1 and ALK fusion genes in Grade 3 were 2.4% (10/421) and 8.3% (35/421), respectively, which were significantly higher than that of 0.5% (7/1 288) and 1.6% (20/1 288) in Grade 2 (P<0.01). In stage-Ⅱ cases, only EGFR mutation rate in Grade 2 adenocarcinoma (31/37, 83.8%) was higher than that in Grade 3 adenocarcinoma (71/123, 57.7%; P<0.01). However, the correlation between the new grade system of IPA and the distribution characteristics of targeted-gene variation cannot be evaluated in stage Ⅲ cases. Conclusions: The new grading system for IPA is mainly applicable to clinical stage-Ⅰ patients. Tumor grades of IPA are strongly correlated with the high-risk factors of prognosis and the distribution features of therapeutic targets. It is of great significance and clinical value to manage postoperative patients with early-stage IPA.

Objective:To analyze the efficacy of the enhanced recovery after surgery(ERAS)approach in endometrial cancer patients treated with surgical staging and its beneficial effects on the oxidative stress response.Methods:Eight-two endometrial cancer patients treated with surgical staging at our hospital between March 2020 and March 2022 were recruited and divided into different groups using a computer-generated random number table, with 41 in the control group who were given routine intervention and 41 in the observation group receiving ERAS.Results:About perioperative performances, the oxidative stress response, inflammatory factor levels and complications were compared between the two groups.Results in the observation group, the intraoperative body surface temperature was higher than in the control group[(36.71±0.22)℃ vs.(36.20±0.21)℃, t=10.737, P=0.000], and the time from the end of surgery to first water intake[(4.41±1.30)h vs.(6.79±1.28)h, t=8.353, P=0.000], to first food intake[(7.86±1.35)h vs.(12.88±2.57)h, t=11.073, P=0.000], to first ambulation[(12.92±3.11)h vs.(24.24±5.06)h, t=12.204, P=0.000], to first flatus[(24.11±4.96)h vs.(35.13±6.20)h, t=8.887, P=0.000], to first bowel movement[(2.67±0.63)d vs.(4.03±1.15)d, t=6.641, P=0.000]and the length of hospitalization[(3.31±1.25)d vs.(5.77±1.59)d, t=7.788, P=0.000]were shorter than in the control group.On the third day after surgery, the levels of malondialdehyde[(77.96±7.62)μmol/L vs.(90.16±7.88)μmol/L, t=7.126, P=0.000], advanced oxidation protein products[(33.16±4.75)μmol/L vs.(43.55±5.37)μmol/L, t=9.280, P=0.000], CAT[(22.59±3.01)U/ml vs.(25.12±3.3)U/ml, t=3.609, P=0.000]and reactive oxygen species[(74.13±5.02)pmol/L vs.(90.33±5.89)pmol/L, t=13.404, P=0.000]in the two groups were higher than those on the day before surgery, but were lower in the observation group than in the control group at the same time points after surgery.On the 3rd day after surgery, the levels of Tumor Necrosis Factor-α, C-reactive protein and interleukin 6 in the two groups were higher than those on the day before surgery, but were lower in the observation group than in the control group at the same points after surgery(all P<0.05). In the observation group, the incidence of complications was 14.63%, lower than 39.02% in the control group( χ2=6.212, P=0.013). Conclusions:The ERAS approach can achieve significant results in endometrial cancer patients treated with surgical staging.It can not only improve perioperative performance, relieve oxidative stress and lower inflammatory factor levels, but also effectively prevent complications.

Primary lung salivary gland-type duct carcinoma: a clinicopathological analysis of two cases and review of literature / 中华病理学杂志

Objective: To investigate the clinicopathological features, diagnostic criteria and differential diagnosis of primary salivary gland-type duct carcinoma of lung(LSDC). Methods: Two patients with LSDC after surgical resection in Shanghai Pulmonary Hospital from 2020 to 2021 were included; their clinical parameters as well as pathological, immunohistochemical and molecular characteristics of the tumors were analyzed. The relevant literature was also reviewed. Results: Both patients were male, aged 49(case 1) and 64(case 2) years, respectively, and with a history of smoking. The chest computed tomography scan showed both lesions to be centrally located. Gross examination showed the maximum diameters were 16 mm and 35 mm, respectively. The histomorphology of LSDC resembled ductal carcinoma of breast, with intraductal islands of neoplastic cells, which also formed solid nests, papillary, micropapillary and cribriform structures. There was frequent accompanying comedo-like necrosis. The neoplasm cells were markedly heteromorphic, possessing large irregular nuclei with prominent nucleoli, abundant eosinophilic or clear cytoplasm, and mitotic figures were common. Both cases of LSDC were immunoreactive for CKpan, CK7, AR, HER2 staining was (2+) and were negative for TTF1, Napsin A, p40, GATA3, mammaglobin, GCDFP15, SOX10, PSA, P504S, ER, PR, vimentin, S-100, SMA, CK5/6 and p63. The tumor showed double-layer cell structure of the duct, and some basal cells/myoepithelial cells expressed p40 and CK5/6. Case 1 had no gene mutation while case 2 harbored TP53 and KMT2A gene mutation detected by next generation sequencing. Conclusions: LSDC is a very rare and highly aggressive salivary-type malignant tumor. The postoperative diagnosis mainly depends on histopathology and immunohistochemistry, attention should be paid to differential diagnosis to prevent missed diagnosis.

Clinicopathological and genetic characteristics of bronchial sialadenoma papilliferum: report of four cases / 中华病理学杂志

Objective: To investigate the clinicopathological, immunophenotypic, and molecular genetic features of bronchial sialadenoma papilliferum (BSP). Methods: Four cases of BSP collected at the Shanghai Pulmonary Hospital from May 2018 to June 2021 were retrieved and analyzed. These cases were evaluated for their clinical, histological, immunohistochemical (IHC) and genomic features. The patients were followed up and relevant literature was reviewed. Results: All four patients were male, aged from 55 to 75 years (mean 62 years), with tumor diameter of 6 to 21 mm (mean 13.5 mm), and lesions were located in the left lower lobe (n=2), right lower lobe (n=1), and trachea (n=1). They were characterized by a combination of surface exophytic endobronchial papillary proliferation and an endophytic two-cell layered ductal structure. IHC staining showed that CK7 and EMA were strongly positive in ductal epithelium; p63, p40, CK5/6 were positive in ductal and papillary basal cells; SOX10 was positive in ductal epithelium and basal cells; S-100 was positive in basal cells and ductal epithelium in two cases. Next generation sequencing showed that two cases harbored BRAF V600E mutation. Conclusions: BSP is an extremely rare primary lung tumor arising from the salivary gland under bronchial mucosa. The primary treatment choice of this tumor is complete surgical resection. The diagnosis and differential diagnosis of this tumor depend on classic histomorphologic and IHC features, and BRAF V600E gene mutation can be detected.

OBJECTIVE@#To verify the clinical effect of acupuncture on knee osteoarthritis (KOA).@*METHODS@#Forty-two patients with KOA were randomly divided into an acupuncture group (21 cases, 1 case dropped off) and a sham acupuncture group (21 cases, 1 case dropped off). The patients in the acupuncture group were treated with routine acupuncture at 5-6 local acupoints [Dubi (ST 35), Neixiyan (EX-LE 4), Heding (EX-LE 2), Yinlingquan (SP 9), Xuehai (SP 10), Zusanli (ST 36), etc.] and 3-4 distal acupoints [Fengshi (GB 31), Waiqiu (GB 36), Xuanzhong (GB 39), Zulinqi (GB 41), etc.]. The patients in the sham acupuncture group were treated with shallow needling technique at non-acupoint. The needles were retained for 30 min in both groups. All the treatment was given three times a week for 8 weeks. Knee injury and osteoarthritis outcome score (KOOS) were recorded before and after treatment and 18-week follow-up.@*RESULTS@#Compared before treatment, the scores of 5 dimensions of KOOS [pain, symptoms (except pain), daily activities, sports and entertainment, and quality of life] were increased after treatment and during follow-up in the two groups (@*CONCLUSION@#Acupuncture can reduce the pain symptoms and improve daily activities in patients with KOA.

Identify Candidate Genes in the Interaction between Abdominal Aortic Aneurysm and Type 2 Diabetes Mellitus by Using Biomedical Discovery Support System / 中国医学科学杂志(英文版)

Objective To explore the candidate genes that play significant roles in the interconnection between abdominal aortic aneurysm (AAA) and type 2 diabetes mellitus (DM). Methods We used the Biomedical Discovery Support System (BITOLA) to screen out the candidate intermediate molecular (CIM) "Gene or Gene Product" that are related to AAA and DM. The dataset of GSE13760, GSE7084, GSE57691, GSE47472 were used to analyze the differentially expressed genes (DEGs) of AAA and DM compared to the healthy status. We used the online tool of Venny 2.1 assisted by manual checking to identify the overlapped DEGs with the CIMs. The Human eFP Browser was applied to examine the tissue specific expression levels of the detected genes in order to recognize strong expressed genes in both human artery and pancreatic tissue. Results There were 86 CIMs suggested by the closed BITOLA system. Among all the DEGs of AAA and DM, 8 genes in GSE7084 (ISG20, ITGAX, DSTN, CCL5, CCR5, AGTR1, CD19, CD44) and 2 genes in GSE13760 (PSMD12, FAS) were found to be overlapped with the 86 CIMs. By manual checking and comparing with tissue-specific gene data through Human eFP Browser, the gene PSMD12 (proteasome 26S subunit, non-ATPase 12) was recognized to be strongly expressed in both the aorta and pancreatic tissue. Conclusion We proposed a hypothesis through text mining that PSMD12 might be involved or potentially involved in the interconnection between AAA and DM, which may provide a new clue for studies on novel therapeutic strategies for the two diseases.

Objective To understand the species composition, density and seasonal variation of adult mosquitoes in Tongliao City of Inner Mongolia Autonmous Region from 2017 to 2019, and to provide scientific data for risk assessment and prediction of mosquito-borne diseases, mosquito-borne control planning, precise implementation and effect evaluation. Methods The density of adult mosquitoes was monitored in parks, hospitals, residential areas, farmers and cattle sheds in Tongliao by using the light trap method. Results A total of 3 358 adult mosquitoes were captured, including Anopheles sinensis, Culex tritaeniorhynchus and Culex quinquefasciatus with Culex quinquefasciatus as the dominant species.The change curve of adult mosquito density with season showed a single peak, and the peak period was from July to September.The density of adult mosquito in cattle shed was the highest (6.71 per night), and that in hospital was the lowest (0.99 per night).The difference between urban and rural areas in seasonal distribution of adult mosquitoes was statistically significant (χ2=4.65, P < 0.05). Conclusion Culex pipiensquinquefasciatus is the dominant mosquito species in the local area, and the villages are the places with high incidence of mosquito infestation.

Inspirations of Rome Ⅳ on clinical evaluation of traditional Chinese medicine for functional gastrointestinal disease / 中国中药杂志

The Rome Foundation released the Rome Ⅳ for functional gastrointestinal diseases (FGIDs) in 2016, which fully presented the latest advances and views on the disease origin, definition, diagnosis, classification, pathology, mechanism, clinical features, influential factors, interventions, clinical evaluation, clinical research design and so on, showing high positive effects on global researches. Traditional Chinese medicines (TCM) have cognitive advantages and well-recognized and-demonstrated efficacy in the prevention and treatment for FGIDs. However, the monotonous presentation ways and weak interpretation on clinical evaluation have also hindered the inherent advantages explanation, characteristics quantization, evidence and communication accumulation. This study first analyzed the background and key points on clinical evaluation of Rome Ⅳ and corresponding inspirations, believed that its concept and viewpoints were assimilated with systematic medicine, and emphasized the important influence of subjective factors such as mental psychology and social culture on the disease and its importance in clinical evaluation. Its views on several aspects such as the theoretical model, internal and external causes, and transfer process were highly consistent with TCM. Therefore, TCM researchers should devote more dedication and courage on the innovation and collaboration with global researches to advance related studies. Then, based on 59 TCM clinical researches for FGIDs funded by national projects upon searching in CNKI with strict search strategy, the clinical evaluation methods and indexes and their correlations were summarized and analyzed, and it was found that more attention was paid to the disease symptoms and impact, symptom/syndrome score, patient report outcome, et al. However, many limitations were also founded, such as disordered relationships among different indexes, ambiguous explanation of research results, and extremely few domestic evaluation instruments in Chinese culture. Therefore, it is suggested that future research should regress and highlight the subjective features of patients and diseases, standardize the elemental structure and management mode of clinical evaluation, enhance the values and status of reported outcomes. It is highly recommended that the domestic disease-specific instruments developed in Chinese culture should be adopted as primary outcome for clinical evaluation, assisted with symptoms/signs assessment tools and doctors reporting outcome scale, et al. The common used TCM syndrome scores in current researches are not recommended as the primary outcome. However, there are some limitations in the above suggestions. We hope that more relevant researches will explore and establish a unified outcome assessment system for FGIDs and improve the quality of TCM clinical research.

Clinical experience and academic thoughts of Professor LIU Feng-bin on case series of gastroesophageal reflux disease based on data mining / 中国中药杂志

To analyze and summarize Professor LIU Feng-bin's clinical experience and academic thoughts on gastroesophageal reflux disease (GERD), the study group adopted the retrospective study for case series and expert interview, extracted the retrospective data, including the herbs, diseases, syndrome type, medical expense and quantity of herbs of GERD patients attended the First Affiliated Hospital of Guangzhou University of Chinese Medicine. Statistical description and binary Logistic regression were used for the identification and modification of syndrome type and initial core herbs. After expert interviews were performed for the syndrome type and herbs, the final scheme were formed. A total of 112 GERD patients ages（48.97±13.13）y; male: 35 (31.3%), female: 77(68.7%) were enrolled. The numbers of patients with liver and stomach incoordination syndrome, heat stagnation of liver and stomach syndrome, syndrome of dual deficiency of Qi and Yin, syndrome of spleen deficiency and dampness-heat, spleen-stomach disharmony syndrome were 40, 26, 19, 17 and 10, respectively. The patients used totally 80 herbs, and 26 of them had significant differences among different syndrome groups. According to the logistic regression analysis on the 23 herbs used by 112 patients, the herbs scheme was modified for the second time. After the expert interviews and modification, the final consensus was reached. The main causes for GERD were dietary irregularities, moodiness, and weak constitution. The basic mechanism of GERD was spleen deficiency with Qi adverseness. The spleen-stomach disharmony syndrome was deleted by expert interviews. The 10 core herbs for GERD treatment were Taizishen(Pseudostellariae Radix), Fuling(Poria), Baizhu(Atractylodismacrocephalae Rhizoma), Gancao(Glycyrrhizae Radix Et Rhizoma), Zhebeimu(Fritillariae Thunbergii Bulbus), Haipiaoxiao(Sepiae Endoconcha), Zhiqiao(Aurantii Fructus), Chenxiang(Alosewood), Pugongying(Taraxaci Herba), Zhizitan(Cape Jasmine Fruit). The modification and psychological and diet interventions were also identified. This study summarized Professor LIU Feng-bin's clinical experience and academic thoughts of chronic atrophic gastritis based on data mining of case series and expert interviews. The quality of methodologies and report were both well. The results provide a foundation and ideas for further study on the complex intervention for GERD, and can be directly applied in clinical practice.

Objective To evaluate the curative effect of the Duhuo-Jisheng decoction in treating knee osteoarthritis (KOA) with the deficiency of liver and kidney. Methods Using the random number table method, a total of 80 KOA patients were randomly divided into 2 group, 40 in each group. The treatment group were treated with Duhuo-Jisheng decoction, and the control group with glucosamine sulfate orally. The 2 groups were treated with 30 day. The blood sedimentation (ESR) of before and after treatment was detected. The level of C-reactive protein (CRP) was detected by latex enhanced immunization. The degree of knee joint pain was evaluated by VAS scale. The severity of the symptoms was evaluated by the visual scale of Osteoarthritis Index (Western Ontario Mac Master University Osteoarthritis index, WOMAC index). The changes of TCM symptoms were observed and the clinical effective rate was evaluated. Results The total effective rate of the treatment group was 95% (38/40), while the control group was 77.5% (31/40). The difference between the 2 groups was statistically significant (χ2=10.213, P=0.003). After treatment, the ESR (15.41 ± 4.23 mm/h vs. 17.6 ± 7.27 mm/h, t=-4.426), CRP (4.73 ± 1.28 mg/L vs. 6.12 ± 2.38 mg/L, t=-14.735) level in the treatemnt group were significantly lower than those in the control group (P<0.01). The VAS scores (2.5 ± 0.62 vs. 4.9 ± 0.8, t=-15.026), WOMAC index(12.1 ± 4.7 vs. 16.7 ± 6.7, t=-11.177) and TCM symptom score (6.5 ± 0.4 vs. 7.5 ± 0.4, t=-3.482) in the treatment group were significantly lower than those in the control group (P<0.01).

Clinical effect of platelet-rich plasma combined with bone graft on bone defect in humeral condylar / 局解手术学杂志

Objective To investigate the effect of platelet-rich plasma(PRP) combined with bone graft in the treatment of humeral condylar bone defect.Methods A total of 135 patients with humeral condylar bone defect in Ankang central hospital from January 2012 to December 2015 were divided into the PRP combined group(n =69) and the conventional group(n =66) according to the order of admission time.The patients of PRP combined group were treated with platelet-rich plasma combined with autologous bone graft,and patients of conventional group received autologous bone graft,respectively.The surgery time,hospitalization time,wound healing,fracture union and the motion of elbow joint at postoperative 1 year between two groups were compared.The Kaplan-Meier survival curve was used to reflect the bone healing in both groups,and the log-rank test was used to compare the result.Results There was no statistically significant difference in the surgery time,hospitalization time,wound healing and motion of elbow joint at postoperative 1 year between the two groups(P ＞ 0.05).But the average time of wound healing (3.8 ± 0.72) weeks and the time of bone union (18.8 ± 3.50) weeks in PRP combined group were significantly shorter than (6.4 ±0.58) weeks and (22.7 ± 1.55) weeks in the conventional group(P =0.000),the differences were significant.The KaplanMeier survival curve of the bone union in the PRP combined group was also significantly better than that in the conventional group.Conclusion PRP can promote the healing of fracture in patients with humeral condylar bone defect after autologous bone graft,which contributes to the recovery of elbow function.

Personalized conformal radiotherapy dose verification with 3D printing cerebral radiation equivalent phantom / 中华放射医学与防护杂志

Objective To establish a method based on 3D printing radiology equivalent phantom for individual radiotherapy dose verification,and to offer an assurance for the safety of 3D conformal radiotherapy.Methods Two patients' CT data was collected,reconstructing the first patient's skull and brain tissue to generate a skull-brain phantom for the purpose of testing the equivalent material.The second patient's data was used for whole head tissue reconstruction to produce a head phantom with equivalent material.By inserting ionization chamber dosimeters to target region for radiotherapy program,equivalent phantom dose distribution of lesions location was obtained in order to verify and calibrate the actual radiation treatment planning for patients.Results DR,CT images of the phantoms revealed that the difference of X-ray gray value between brain skull phantom and patient's skull was 13 721,CT value difference between equivalent tissue of brain skull phantom and that part of the patient was 35-40 HU,and CT difference between head phantom temporalis and that of the patient tissue was 18-28 HU.The imaging data indicated that the radiation equivalence of 3D printing phantom was similar to that of human body tissue,and the equivalent dose distribution accorded well with the normal range of treatment.The dose verification of phantom model can effectively improve the accuracy of the radiotherapy system.Conclusions The personalized radiotherapy phantom which based on the 3D printing and tissue equivalent technology is suitable for personalized radiation therapy validation.With advantages of easy accessibility,highly-personalized degree and high precision,this technology provides a reliable and safe way for radiation therapy.

Controversies on the values for health instruments of Chinese medicine / 中国结合医学杂志

Currently, there are increasing debates on the necessity of health instruments in Chinese medicine (CM) emerging in China. This study aims to reevaluate its status and values. Analyzing the causes, limits, advantages, and properties characters of health instruments in CM, it is found that weak fundamental research, incomplete self-awareness, and complicated social factors are the primary causes of debates. A comprehensive analysis showed health instruments in CM have health evaluation benefits to people from a dominant Chinese culture, meet the requirements of cultural background, and bring long-term value to Chinese instrument researches. However, its values and status should be treated differently depending on various subtypes. Although little theoretical and practical evidences proved that patients-reported health instruments in CM should be proposed independently, the doctors- and nurses-reported questionnaires are necessary. With this in mind, the study group proposes the 'Chinese cultural instruments (CCIs)' and 'health-related CCIs'. The latter one aims to evaluate the health status of people in a dominant Chinese culture. The CCIs theory represents Chinese instrument researches on a larger regional and higher level, and resolves the debates on instruments between CM and Western medicine in China. Health instruments in CM bring more scientific and social benefits for Chinese instrument researches. However, it does not include cultural demands, and lacks scientific significance. CCIs have all its virtues, and add solutions to the latter's theory bottleneck and scientific debates, thus bringing increased benefits to clinical assessment in complementary and alternative medicine researches.

Traditional Chinese medicine syndrome distribution and neuroendocrine mechanisms of irritable bowel syndrome: cross-sectional study / 中国中药杂志

In order to clarify the traditional Chinese medicine(TCM) syndrome distribution and pathogenesis of irritable bowel syndrome(IBS), the patients in the first affiliated hospital of Guangzhou university of Chinese medicine were enrolled for the cross-sectional study. The data of 12 sociological variables, 13 risk factors, 84 symptoms and signs variables(in 9 aspects), and 19 neuroendocrine indices were extracted for group-between analysis with one-way ANOVA, chi-square test and nonparametric test, and the relationship analysis between clinical symptoms and diseases sub-types was done with binary Logistic regression. In addition, the patterns of TCM syndromes were divided by several syndrome factors to analyze the difference in neuroendocrine indices between various patterns and syndrome factors. A total of 383 IBS patients were enrolled, including 353(92.2%) cases of diarrhea, 14(3.7%) cases of constipation and 16(4.1%) cases of mixed types. In IBS-diarrhea patients, there were 291(76.0%), 18(4.7%), 48(12.5%) and 26(6.8%)cases of syndrome of liver depression and spleen deficiency (sLDSD), syndrome of liver depression and qi stagnation (sLDQS), syndrome of dampness-heat in the spleen and stomach (sDHSS), and syndrome of spleen deficiency with dampness encumbrance (sSDDE) respectively. There was significant differences in blood groups between IBS-diarrhea patients, IBS-constipation patients and IBS-mixed types patients; their disease classification was significantly correlated with the allergies, drinking, irregular meals habits, no or less vacations, and other causes of morbidity (P<0.05, f<0.3). A total of 15 symptoms and signs variables (e.g., chills, facial abnormalities, epigastric fullness, etc.) had significant differences between different groups (P<0.05), and 5, 8, 5 variables were respective independent factors for IBS-diarrhea, constipation and mixed type. There was no significant difference in neuroendocrine indices between various groups. The sLDSD, sLDQS, sDHSS, sSDDE patients had significant differences in genders, living conditions and occupations, and the TCM syndrome type was significantly correlated with the drinking, smoking, no or less breakfast, less than 8 sleeping hours(P<0.05, f<0.3). Meanwhile, a total of 14 symptoms and signs variables (e.g., dysphoria heat, fatigue, stretching, etc.) had significant differences between various groups(P<0.05) and 3, 4, 6, 3 variables were respective independent factors for sLDSD, sLDQS, sDHSS, and sSDDE. There were significant differences in acetylcholine(Ach) and angiotensin Ⅱ(AT-Ⅱ) between the sLDSD group and sSDDE group. There were significant difference in Ach, AT-Ⅱ, adrenotrophin(ACTH) and estradiol (E2) in comparison between several pattern factors. This study preliminary identified the sociological characters, risk factors, syndromes distribution, diseases and subgroup mechanisms of this disease. More samples and multi-centers are required for future study to improve the scientificity and representativeness.
