Objective Implanting surgical meshes to support breast in periareoler mammaplasty shows an excellent prospect.But shrinking of the mesh and the adhesion formation affected the postoperative shape and palpation of the breast.The aim of this study was to compare biocompatible properties of four different polypropylene meshes (Prolene(R) ; Vypro Ⅱ(R) ; Premilene Mesh (R) and Premilene Mesh LP(R)) and to discuss the inclusion criteria of meshes in this technique.Methods The study was carried out in pigs.Four different polypropylene meshes were implanted subcutaneously in belly.90 days after implantation the mesh samples were explanted,and complications,foreign-body reaction,collagen fiber and elastic fiber formation were observed,as well as ultrastructures for the biocompatible properties.Results The biocompatible properties of each mesh were different.The foreign-body reactions determined the biocompatible properties,and affected the postoperative shape greatly.Conclusions Premilene Mesh LP o as a newer low-weight polypropylene mesh,has superior properties to the others.

Objective To summarize our experiences in the diagnosis and prognosis of different subtypes of primary thyroid lymphoma (PTL). Methods The clinical data of 27 PTL patients who were treated in our hospital from January 1998 to December 2014 were retrospectively analyzed. The pathological types of these patients included B cell lymphoma unclassifiable (BCLU) (n=5),mucosa-associated lymphiod tissue lymphoma (MALT) (n=9),diffuse large B cell lymphoma (DLBCL) (n=12),and T cell lymphoma (n=1). Results Of all these 27 cases,the most common clinical symptom was painless swelling of the neck (n=21,77.8%). Of 7 patients who had received preoperative fine needle biopsy,lymphoma was suspected in 2 cases (28.6%). Among these 7 cases,the positive rate of suspicious lymphoma was 66.7% in 3 DLBCL patients,0 in 3 MALT patients,and 0 in 1 BCLU paitent. Also,25 patients underwent intraoperative frozen pathological examination,which revealed lymphoma or suspicious lymphoma in 16 cases (64.0%); in these patients,the positive rate was 66.7% for BCLU,77.8% for MALT,58.3% for DLBCL,and 0 for T-cell lymphomas. The overall survival was (89.3±12.4) months,and the overall 5-year survival rate was 61.6%. The estimated survival in symptomatic group was 31.6 months,which was significantly shorter than that in asymptomatic group (97.9 months) (P=0.032). Other factors including age,sex,tumor size,tumor stage,international prognostic index,tracheal compression,lactate dehydrogenase,residual tumor,and pathological type showed no significant effect on survival(all P>0.05). Conclusions DLBCL has the highest fine needle biopsy positive rate,MALT has the highest frozen pathological positive rate,and intraoperative frozen pathology has more malignant results than the preoperative fine needle biopsy in the diagnosis. The accompanying lymphoma symptoms may be an adverse prognostic factor.

Objective To investigate the effect of all-in-one nursing intervention on esophageal carcinoma patients with bad emotion and immune function. Methods From the October, 2012 to the October, 2013, 102 patients with radical operation of esophageal carcinoma were divided into all-in-one nursing intervention group (research group, 52cases) and routine nursing group (control group, 50 cases) according to the random number table method.Two groups of patients were evaluated before and after operation of anxiety and depression emotion scores, with the Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) .At the same time, two groups of patients were detected the stress and immune index before and after the operation. Results Before operation, two groups of patients with anxiety, depression, stress reaction and immune index were not significantly different (P>0.05).After operation, the study group patients with anxiety and depression scores were significantly lower than those in the control group [(34.6+6.7) points vs. (44.8+7.5) points, (33.7+6.9) points vs. (40.6+7.3) points], the difference was statistically significant (t values were 7.234, 4.902, P<0.05). Eighth days after operation, patients in the control group FBG, CRP and Cor levels were significantly higher in the study group [(6.98±1.12)mmol/L vs.(6.09±0.85)mmol/L,(18.11±5.93) mg/L vs.(9.24±3.22)mg/L,(293.98±69.09)nmol/L vs.(221.97±67.94)nmol/L],the difference was statistically significant (t values were 4.532, 9.336, 5.307, P<0.05). Eighth days after operation, two groups of patients with IgA, IgM were higher than first days after operation [(2.41±0.46)g/L vs.(1.89±0.56)g/L,(2.51±0.58) g/L vs.(1.35±0.67)g/L and (2.36±0.53)g/L vs.(1.82±0.46)g/L, (2.34±0.62)g/L vs. (1.37±0.64) g/L], the difference was statistically significant (t values were 5.174, 9.439, 5.549, 7.850, P<0.05).The total number of patients blood lymphocytes (LYM) and cytokines (CD3, CD4, CD8, CD4/CD8) were significantly higher than the control group [(2.87±0.65)×109/L vs.(1.98±0.58)×109/L, 0.62±0.10 vs. 0.57±0.07, 0.41±0.08 vs. 0.35 ±0.08, 0.24 ±0.04 vs. 0.26 ±0.05, 2.06 ±0.44 vs. 1.65 ±0.46], the difference was statistically significant (t values were 7.286, 2.915, 6.942, 2.225, 4.601, P<0.05). Conclusion All-in-one nursing intervention can significantly improve the anxiety and depression in patients with esophageal cancer in bad mood, enhance the immune function of patients, conducive to the rehabilitation of patients.

Objective Mesenteric panniculitis is an idiopathic , uncommon disease involving the adipose tissue of mesentery .The etiology , diagnosis and treatment are still unnoticed .We thus reported a case series to improve the understanding of this rare disorder .Methods We retrospectively analyzed the clinical data of 12 patients with mesenteric panniculitis including manifestation , diagnosis, treatment and prognosis.Results We found a male predominance (M∶F 3∶1) with the median age of 58 years old at diagnosis.The most common symptom was abdominal pain (9/12), followed by abdominal distension (3/12) and weight loss (3/12).Physical examination was unremarkable in the majority of patients (8/12).C reactive protein (9/12) and erythrocyte sedimentation rate (10/12) were normal in majority of patients.CT findings were of much diagnostic value .All patients had small intestinal mesentery involvement and multi-nodular appearance with increased fat density .Pseudo-capsule sign ( 8/12 ) and fat halo sign (6/12) were common.Pathological diagnosis was obtained in 4 cases showing fat tissue inflammation with local necrosis and fibrosis .Six cases all received prednisone , 2 with combined cyclophosphamide , 1 with azathioprine, 1 with tripterygium wilfordii .Short-term clinical response was achieved in all cases , but two patients relapsed .Conclusions Mesenteric panniculitis occurs predominantly in middle-aged and elderly . Abdominal pain is the leading symptom .Inflammatory markers are often normal while computed tomography is the most important diagnostic tool .Surgery combined with cortical steroid and immunosuppressant agents is effective.

Objective: Pulmonary metastatic angiosarcoma is a rare, fatal disease that often presents as diffuse alveolar hemorrhage(DAH). In this report, clinical characteristics of pulmonary metastatic angiosarcoma were retrospectively reviewed. Methods: A total of 9 patients with angiosarcoma who presented as DAH were enrolled. Clinical data included age, gender, symptoms, smoking status, physical exam findings, pulmonary function tests, and radiology. Results: All patients were male with median age 41 years(range, 22 to 57 years). The most common symptom was hemoptysis(9/9). Other symptoms included dyspnea (5/9), cough(3/9), chest pain(3/9), fever(2/9,) and edema of the lower extremity and oliguria(4/9).The common misdiagnoses were tuberculosis(4/9), vasculitis(3/9) and other infection(1/9). Chest computed tomography showed bilateral,random distributed different-sized nodules(9/9),as well as ground-glass areas (9/9).The hearts, mainly right atrium, were the most common primary locations(7/9).Cardiac mass was the first manifestation in five patients by echocardiography(5/8).Two atrial masses were identified by computer tomography pulmonary angiography and magnetic resonance imaging respectively. Transbronchial lung biopsy failed to find malignancy. Computer tomography guided transthoracic needle biopsy was difficult to perform in most patients. Eight patients were diagnosed by surgical biopsy, either by lung biopsy(4/8) or cardiac biopsy(4/8).The median survival period was only 3 months after surgery. Conclusion Metastatic pulmonary angiosarcoma should be considered in patients with DAH and multiple glass ground opacity and nodules on chest CT. Careful cardiologic monitoring is necessary. Surgical biopsy is reliable for diagnosis.

Few preoperative extrapontine myelinolysis (EPM) cases with pituitary adenoma have been reported. No such case had long follow-up to see the outcome of EPM. We reported a 38-year-old man complaining of nausea, malaise and transient loss of consciousness who was found to have severe hyponatremia. Neurologic deficits including altered mental status, behavioral disturbances, dysarthria and dysphagia developed despite slow correction of hyponatremia. Endocrine and imaging studies revealed hypopituitarism, nonfunctional pituitary macroadenoma and extrapontine myelinolysis. Transsphenoidal surgery was performed after three weeks of supportive therapy, when neurological symptoms improved significantly. The patient recovered function completely 3 months after surgery. Our case indicates that outcome of EPM can be good even with prolonged periods of severe neurologic impairment.

Objective: To investigate the clinical and pathological features, diagnosis and treatment of primary vulvar Paget disease (VPD) , and analyze the related factors that may affect the recurrence. Methods: A retrospective study was carried out on 36 patients diagnosed as VPD pathologically from January 1983 to December 2017 at Peking Union Medical College Hospital, Chinese Academy of Medical Sciences. The clinical and pathological features, diagnosis, treatment and prognosis and the factors influencing recurrence rate of VPD were analyzed. Results: (1) Totally 94% (34/36) of VPD occurred in postmenopausal women. Pruritus was counted 86% (31/36) of the main complaint. Lesions of vulvar were main symptom which had no specificity, acting as ulcer (67%, 24/36) , erythema (50%, 18/36) , depigmentation (42%, 15/36) , sclerosis (31%, 11/36) , and pigmentation (17%, 6/36) . The lesions invaded labium majus (97%, 35/36) , sometimes labium minus (53%, 19/36) , clitoris (28%, 10/36) , perianal (25%, 9/36) , orificium vaginae (3%, 1/36) , and meatus urinarius (3%, 1/36) . Approximately 19% (7/36) of VPD coexisted with intraepithelial neoplasia or adenocarcinoma of vulvar or other part of body. (2) Diagnosis and treatment: diagnosis was confirmed histologically by biopsy or pathologies after surgery, and immunohistochemical results were helpful for differential diagnosis. Surgery was the mean treatment method, 34 of all the 36 patients (94%, 34/36) underwent surgery for at least once, while 2 patients (6%, 2/36) were performed non-operative treatment. The surgical treatment included excision of focus, wide local excision, simple vulvectomy, and extensive vulvectomy. The non-operative treatment included radiotherapy, chemotherapy, laser, photodynamic therapy, and so on. (3) Prognosis: among 36 VPD patients, 4 were lost to follow-up with a 89% (32/36) follow-up rate. Median follow-up was 35.3 months (range,1 month to 31 years) . During the follow-up period, 2 patients were unable to judge whether they will relapse for the follow-up time did not reach half a year, 8 cases were unsuccessful operation, 20 cases succeeded, the achievement ratio was 71% (20/28) . Nine of twenty cases relapsed, the recurrence rate was 45% (9/20) . The median recurrence time was 14 months after operation. One patient of the 32 followed-up patients died, the mortality rate was 3% (1/32) . (4) The related factors affected the recurrence of VPD: t test was applied to the analysis of patients′ age, rank test was used in the statistics of the time of confirmed diagnosis, the length and thickness of the resection focus. Fisher test was used to calculate whether the focus were limited to the epidermis, type of surgical procedures, distance between the margin and the focus, whether tumor cells infiltrated the margin. The results showed that none of the above terms in the first operation had significant contribution to recurrence (all P>0.05) . Conclusions VPD may be a low potential malignancy, which could slowly progress into deep invasive disease. VPD is often associated with intraepithelial neoplasia or primary tumors of the vulva or somewhere else. Operations is the first choice for VPD, but consider for its high recurrence rate after operation, close follow-up should be strongly suggested.

Background::The causal relationship between visceral adipose tissue (VAT) and gout is still unclear. We aimed to examine the potential association between them using observational and Mendelian randomization (MR) analyses.Methods::In the observational analyses, a total of 11,967 participants (aged 39.5 ± 11.5 years) were included from the National Health and Nutrition Examination Survey. Logistic regression models were used to investigate the association between VAT mass and the risk of gout. In two-sample MR analyses, 211 VAT mass-related independent genetic variants (derived from genome-wide association studies in 325,153 UK biobank participants) were used as instrumental variables. The random-effects inverse-variance weighted (IVW) method was used as the primary analysis. Additional sensitivity analyses were also performed to validate our results.Results::Observational analyses found that an increase in VAT mass (per standard deviation) was associated with a higher risk of gout after controlling for confounding factors (odds ratio [OR] = 1.27, 95% confidence intervals [CI] = 1.11–1.45). The two-sample MR analyses demonstrated a causal relationship between increased VAT mass and the risk of gout in primary analyses (OR = 1.78, 95% CI = 1.57–2.03). Sensitivity analyses also showed similar findings, including MR-Egger, weighted median, simple mode, weighted mode, and leave-one-out analyses.Conclusions::Observational analyses showed a robust association of VAT mass with the risk of gout. Meanwhile, MR analyses also provided evidence of a causal relationship between them. In summary, our findings suggested that targeted interventions for VAT mass may be beneficial to prevent gout.

The pathogenesis of diabetic nephropathy(DN)is very complex.Ferroptosis as a kind of new way of cell death has become a research hotspot in recent years.It is widely known that DN is closely related to ferroptosis.Deactivation of system Xc--GSH-GPX4 axis,iron overload,lipid peroxidation and mitochondrial dysfunction play important role in occurrence and development of ferroptosis of DN,antioxidant protein may be a potential target for the treatment of ferroptosis of DN.Different pathways and interactions may alleviate the occurrence and development of ferroptosis by activating antioxidant protein such as GPX4,Nrf2,Sirtuin family protein and ferritin.Traditional Chinese medicine(TCM)has the characteristics of multi-component,multi-target and multi-pathway overall regulation.The active components and compounds of TCM have potential application value in improving renal injury and ferroptosis of DN by enhancing the expression of antioxidant protein,which provides a new research direction for delaying the progress of DN.

Objective To investigate the effect of acupuncture point injection and rehabilitation on the functional recovery of upper limbs and daily living ability of shoulder-hard syndrom (SHS) after cerebral hemorrhage. Methods A total of 96 patients SHS after cerebral hemorrhage were divided into the observation group (n=56) and the control group (n=40). Both groups recieved the routine treatment for cerebral hemorrhage and rehabilitation technique training. Besides, the control group was treated with intermediate frequency physiotherapy, and the observation group was treated with electroacupuncture and acupoint injection of Salvia miltiorrhiza and ligustrazine. After 1 months of treatment, the the upper limb movement function, daily living ability (ADL), shoulder joint pain, joint activity degree, and the degree of joint swelling were evaluated and compared. Results After treatment, the FMA (60.1 ± 6.4 vs. 41.8 ± 18.7, t=6.799), MBI (65.2 ± 3.5 vs. 50.6 ± 2.1, t=23.512) scores of the observation group were significantly higher than those of the control group. The VAS (2.7 ± 1.4 vs. 4.9 ± 1.3, t=7.817), edema volume (2.1 ± 2.1 cm3 vs. 2.1 ± 2.1 cm3, t=7.316) of the observation group were significantly lower than those of the control group ( P＜0.01). The anterior flexion (163.1 ± 6.7°vs. 56 ± 10.9°, t=59.516), extension (39.6 ± 5.8°vs. 23.2 ± 6.7°, t=12.799), abduction (168.1 ± 9.6°vs. 52.1 ± 8.9°, t=60.148), adduction (52.1 ± 3.6°vs. 29.8 ± 4.3°, t=27.580), external rotation (49.8 ± 7.6°vs. 23.2 ± 5.2°, t=19.151), internal rotation (107.0 ± 8.5°vs. 60.2 ± 6.1°, t=29.758) of the observation group were significantly higher than those of the control group (P＜0.01). The total effective rate of the observation group was 91.1% (52/56) and the control group was 70% (28/40), and the difference between the 2 groups was statistically significant (χ2=7.209, P＜0.01). Conclusions Acupuncture combined with acupoint injection and rehabilitation technology can relieve pain, eliminate edema and improve motor function and daily living ability of SHS patients after intracerebral hemorrhage.
