Objective To reform the teaching content of acupuncture and moxibustion for undergraduate of Nursing College and to evaluate the effectiveness of the teaching reform,so to provide constructive information for optimizing the curriculum.Methods To revise the teaching content of Traditional Chinese Medicine(TCM)acu-puncture course based on the results of previous questionnaires,including reducing boring theoretical knowledge,increasing commonly used acupuncture techniques and clinical case analysis,organizing all undergraduates atten-ding the TCM teaching in the Nursing College of Peking Union Medical College to fill out the"Acupuncture Course Content Questionnaire"in 2023.The content covers four aspects:students'basic cognition of acupuncture and moxibustion before the course,students' learning feedback,students'learning effectiveness after the course and students' suggestions for further optimization of acupuncture and moxibustion course.Results Totally 149 students participated in the questionnaire survey and 73.15%of them were interested in the acupuncture course.There were 62.42%of the students thought that the most difficult part of the course was the"Acupuncture Points",and 71.81%of them complained the most constraining factor to the learning effectiveness was the diffi-culty of memorizing the meridians and acupoints.The most interesting part of the course was"Overview of Acu-puncture Treatment and Acupuncture Treatment of Common Diseases",which accounted for 44.3%of the students.Through the study,88.59%of the students were willing to recommend acupuncture treatment to pa-tients with indications.Students' suggestions for improvement of the acupuncture course was increase of classroom practice or learning by observation of operation videos.Conclusions The reformed acupuncture course highlights the practicability,improves the learning interest and subjective initiative,but the training of practice skill still needs to be strengthened.

Objective:To investigate the clinical characteristics of psoriasis and status quo of medical care for patients in county areas of China.Methods:This study was a cross-sectional investigation. Based on the “Qianxian Wuyin” Project (a national project for upgrating ability for psoriasis care at county level), an online questionnaire survey was conducted in the dermatology departments of 459 county hospitals in 404 pilot administrative counties across China from February to June 2023. The questionnaire included demographic information of patients (gender, ethnicity, age, place of residence, education, marital status), and clinical characteristics of psoriasis (disease course, type, comorbidities, body surface area (BSA) and previous treatment. The Dermatology Life Quality Index (DLQI) and Psoriasis Area and Severity Index (PASI) were applied for assessing the quality of life and disease severity, and completed by patients or guardian and doctors, respectively.Results:A total of 16 935 patients completed the questionnaire. The age of patients was 1-102(44.17±11.58)years, and 71.0% (12 036/16 935) were 30-59 years old. The ratio of male to female was 2.21∶1; 24.3%(4 117/16 935) of patients had high school education; there were 9 940 patients(58.7%) with previous or current smoking and/or alcohol use; 42.8%(7 218/16 855) of patients had a disease course of 1-5 years. There were 15 630 patients(92.3%) with DLQI≥10, 8 346 patients(49.7%) with PASI≥10, 15 017 patients(89.2%) with BSA≥10%. The plaque type was the most common disease type ( n=14 965, 88.7%), and spotting type ranked the second ( n=1 141, 6.8%). The most common initial site was the trunk ( n=12 309, 72.9%). Among the comorbidities, hypertension was the most common one ( n=1 681, 10.0%). There were 7 650 reports of treatment response to conventional topical drug therapy and 3 112 reports of treatment response to systemic drug therapy, with 6 269 (81.9%) and 2 493 (80.1%) reporting poor or no response, respectively. Conclusions:The survey shows that in the county areas of China, the majority of psoriasis patients are severe patients with short course of disease, plaque type is the most common type, and hypertension is the most common comorbidity; and the conventional treatment is less effective for most patients.

Objective: To explore the effect of different midwifery methods on the pelvic floor function of parturients and nursing experience. Methods: From January 2018 to December 2018, 200 cases of vaginal delivery in Enze Obstetrics and Gynecology Hospital of Taizhou Hospital were selected as study objects.According to the random number table method, they were divided into non-invasive midwifery group and traditional midwifery group, with 100 cases in each group.The non-invasive midwifery group adopted non-invasive midwifery, while the traditional midwifery group adopted traditional midwifery.The pelvic floor muscle strength, pelvic floor muscle dysfunction and postpartum hemorrhage were observed in the two groups. Results: There was no statistically significant difference in pelvic floor muscle strength between the two groups in grade 0, grade Ⅰ, grade Ⅱ, grade Ⅲ and grade Ⅳ(all P>0.05). The pelvic floor muscle strength of the observation group in grade Ⅴ (45.00%) was higher than that of the control group (31.00%), the difference was statistically significant (χ²=4.160, P<0.05). The incidence of sexual dysfunction (15.00%) and stress urinary incontinence (28.00%) in the observation group were significantly lower than those in the control group (41.00%, 54.00%) (χ²=16.766, 13.973, all P<0.05). The amount of bleeding 2 hours after delivery in the observation group [(245.93±19.89)mL] was less than that in the control group [(297.42±24.21)mL] (t=16.433, P<0.05). Conclusion Non-invasive midwifery has little effect on the pelvic floor function of parturients, and the incidence rate of sexual dysfunction and stress urinary incontinence is low, and the amount of bleeding is small, which is worthy of clinical reference.

Objective: To study the clinicopathologic characteristics and diagnostic criteria of primary mediastinal B-cell lymphoma (PMBL), and to distinguish PMBL from classic Hodgkin lymphoma(CHL) and systemic diffuse large B-cell lymphoma(DLBCL). Methods: The clinical features, histologic findings, results of immunohistochemical study and prgnosis in 27 PMBL cases were analyzed, with review of literature. Results: The age of patients ranged from 19 to 82 years (median age 34 years). All cases were located in the mediastinum and frequently accompanied by superior vein cava syndrome. Histologically, the tumor cells were pleomorphic and diffusely distributed. Clear cytoplasm and spindle tumor cells were seen in some cases. Varying amount of sclerosing stroma with collagen deposition was seen.Immunohistochemical study showed that the tumor cells were positive for CD20(100%, 27/27), CD30 (64.0%, 16/25), CD23 (77.3%, 17/22) and p63 (16/19). Clonal B cell gene rearrangement was seen. Conclusions PMBL is a subtype of diffuse large B-cell lymphoma with various histomorphology. Immunohistochemistry can help to confirm the diagnosis, and the prognosis is better than diffuse large B cell lymphoma, not otherwise specified.

Objective To determine the prevalence and treatment of chronic obstructive pulmonary diseases (COPD) among citizens in Ningbo. Methods A multi-stage stratified random sampling was applied to select 8 neighborhoods and 3 villages out of 7 districts in Ningbo, people who were older than or equal to 40 years were enrolled as subjects. Information on the prevalence rate and treatment conditions of COPD was collected through respiratory symptoms and treatment questionnaire and lung function screening. Results A total of 5865 people were screened, 5674 of them met inclusion criteria and completed questionnaire and lung function test. Among whom, 3044 people were men (53.6%, the average age is 55.7±11.4), 2630 women (46.4%, the average age was 55.3 ± 10.7);473 of them were diagnosed with COPD, the overall prevalence rate was 8.3%, including 354 cases who had never been diagnosed as COPD, accounted for 74.8% of the total cases diagnosed with COPD, mainly in stage ⅠandⅡof the disease. There were statistically significant differences between diagnosed and undiagnosed patients in the overall COPD group and among different gender groups ( stagesⅠandⅡ) and (stagesⅢandⅣ). Among the 473 COPD cases, 119 (diagnostic yield 25.2%) of whom had been diagnosed with bronchitis, only 48 (41.2%of the diagnosed) received drug treatment, only 13 patients were treated regularly with medication. Conclusion The overall prevalence rate of COPD among those over 40 years of age in Ningbo was quite high and mainly had stagesⅠandⅡof the disease. The number of the diagnostic yield and those who received regular treatment are quite low. The current situation of diagnosis and treatment are far from satisfaction, management of COPD should be strengthened to reduce the burden for family and society.

Aim To study the effects of Free Anthra-quinone from Rhubarb (FAR)on myocardial CTGF and collagen expression and interstitial fibrosis in dia-betic rats.Methods The male SD rats were randomly divided into normal group (CON),diabetic cardiomy-opathy group (DCM) and FAR treatment group (FAR).Streptozocin was intraperitoneally injected in-to the animals in the latter 2 groups to induce diabetic rat model.The model was expected to be stable for 2 weeks before the treatment.At the end of the 8th week in treatment,fasting plasma glucose and heart mass in-dex were measured.Masson staining was used to ob-serve the myocardial fibrosis.RT-PCR was used to de-tect the mRNA levels of CTGF,procollagen type Ⅰand collagen type Ⅲ.Immunohistochemical method was used to detect the content of CTGF.ELISA was used to detect the depositions of collagen type I and collagen type Ⅲ. Results Compared with CON group,fasting plasma glucose,heart mass index,the degree of myocardial fibrosis,and the expressions of CTGF,collagen type I and collagen type Ⅲ in left ven-tricular myocardial tissue of DCM group were signifi-cantly increased. However, compared with DCM group,fasting plasma glucose,heart mass index,the degree of myocardial fibrosis,and the expressions of CTGF,collagen type I and collagen type Ⅲ in left ven-tricular myocardial tissue of FAR-treated rats were sig-nificantly decreased.Conclusion FAR retards the process of myocardial fibrosis in diabetic rats by down-regulating the expression of CTGF,reducing the syn-thesis and depositions of collagen type I and collagen type Ⅲ.

Objective Cervical lymph node enlargement may be attributed to inflammation or tumors .This study was to analyze the pitfalls in fine-needle aspiration cytology ( FNAC) of cervical lymph nodes and the measures for avoiding misdiagnosis of cervical lymph node lesions . Methods We retrospectively analyzed the data about 435 cases of FNAC in comparison with the results of corre-sponding tissue biopsies in cervical lymph nodes . Results Among the 435 cases, 7 showed disagreement between the results of cytolog-ic and histologic diagnoses, which included 5 males and 2 females, at the age of 41 to 71 (58.4 ±8.9) years.Six of the cases presented with local lymph node enlargement and 1 with generalized lymphadenopathy, all with enlarged lymph nodes palpable 1-4 cm in diameter . Based on the results of FNAC, 1 case of malignant lymphoma was misdiagnosed as lowly differentiated adenocarcinoma, 1 case of lympho-ma misdiagnosed as poorly differentiated metastatic carcinoma, 2 cases of lymphoma diagnosed as lymphoproliferation and recommended for biopsy, 1 case suggestive of malignant tumor without further classification, and 2 cases microscopically characterized and recommended for lymph node biopsy.Compared with the results of the biopsy, FNAC achieved a 99.3%coincidence rate of qualitative diagnosis (432/425), with a misdiagnosis rate of 1.6%(7/435). Conclusion FNAC plays a very important role in the initial identification of the nature of lymph node lesions and the type of tumors.Practiced puncture skills and intimate knowledge about the histopathological features, diagnostic criteria, and differential diagnosis of the lymphatic system disorders are essential for improving the diagnostic accuracy of FNAC .

Diabetic nephropathy (DN) is the leading cause of end-stage failure of the kidney, but the efficacy of currently available strategies for the prevention of DN remains unsatisfactory. In this study, we investigated the effects of free anthraquinones (FARs) extract, which was extracted from the rhubarb and purified by macroporous resin DM130 with gradient mixtures of ethanol/water as the lelution solvents, in high glucose-cultured glomerular mesangial cells (MCs). The cell proliferation was determined by CCK-8 assay, the levels of TGF-beta1, CTGF, ColIV and FN proteins in the supernatant of MCs were measured by ELISA assays, and the mRNA levels of these four genes were detected by RT-PCR. The results showed that the increased proliferation of MCs, the mRNA levels and protein expression of TGF-beta1, CTGF, ColIV and FN induced by high glucose were inhibited after the treatment with the FARs extract. This indicated that FARs extract could inhibit cell proliferation and the expression of main extracellular matrix induced by high glucose in MCs. The FARs extract exhibited potential values for prophylaxis and therapy of DN.

Objective To explore influences of bedside sitting nursing on mechanical ventilation duration of patients with chronic obstructive pulmonary disease (COPD). Methods Ninety six patients with COPD admitted in the hospital from January 2013 to January 2014 were selected as research subjects, who were divided into control group and obser-vation group with 48 patients in each group according to different nursing modes. The patients in the control group were subjected to conventional treatment and nursing, while the patients in the observation group were subjected to bedside sitting nursing on the basis of that applied in the control group, mechanical ventilation duration, length of hospital stay, changes in blood and vigor indexes before and after nursing of two groups of patients were compared and analyzed. Re-sults The differences in comparisons of PaO2, PaCO2 and SpO2 levels of patients in two groups had no statistically signif-icant before nursing (P>0.05); and PaO2, PaCO2 and SpO2 levels of patients in the observation group after nursing were better than those indexes of patients in the control group (P<0.05). Mechanical ventilation duration and length of hospital stay of patients in the observation group were lower than those of patients in the control group, the successful removal of respirators used in the observation hit was 85.4%, was higher than 64.6% in the control group, the incidence of ven-tilator associated pneumonia was 4.2%, was lower than 22.9% in the control group, and the difference was significant (P<0.05). Conclusion The bedside sitting position can effectively improve the ventilation function of patients with COPD, reduce the duration of mechanical ventilation, decrease the occurrence of ventilator associated pneumonia, shorten hospitalization time, and improve the quality of survival, delivering high clinical application value.

Objective To observe the effect of injectable tissue-engineered bone in treating periarticular bone fracture nonunion under arthroscopy. Methods Selected 6 patients with intra-articular bone fracture nonunion:3 cases of humerus intercondylar fracture;2 cases of femoral condylar fracture and 1 cases of tibial plateau fracture. All of the 6 patients have undergone arthroscopic debridment and tissue-engi-neered bone injection in the the fracture ends with puncture needle under direct vision. Percutaneous needle internal fixation were performed if necessary. All the patients have got regular follow-up after the operation process. Check their healing condition with X-ray examination, and the healing of the bone and its complications have also been monitored. Reexamination were made 3, 6, 9, and 12 months after surgery. Results All the patients have experienced successful operation and all the fracture have healed up. The X-ray review showed that the callus healing time was (8. 34 ± 2. 4) weeks and fracture healing time was (18. 2 ± 3. 3) weeks. Accordong to Johner-Wruhs functional category, there were 5 cases of excellent recovery and 1 case of medium recovery. Among these patients, inflammatory reaction occurred in 1 case, and the symptoms disappeared after 2 weeks of Vancomycin anti-inflammatory treatment; deep venous thrombosis occurred in 1 case, and the symptoms disappeared after systematic anticoagulant therapy. Conclusion It’ s safe and effective to treat periarticular bone fracture nonunion with injectable tissue-engineered bone under arthroscopy.
