Effect of incision and thread-drawing selective suture in the treatment of high complex anal fistula and its influence on anal function and complications / 国际外科学杂志

Objective:To investigate the therapeutic effect of open suture and selective suture in patients with high complexity anal fistula and its effect on anal function and complications.Methods:Prospectively selected 174 patients with high complex anal fistula who were hospitalized in the Anorectal Surgery Department of the Second People′s Hospital of Yibin City from December 2018 to December 2021 as the study subjects, including 138 males and 36 females, aged from 26 to 45 years, with an average of (35.20 ± 8.86) years. According to the admission order of patients, grouped them into single and double numbers, with single numbers being the control group ( n=87) and double numbers being the observation group ( n=87). The control group was treated with traditional incision and thread hanging therapy, while the observation group was treated with selective suture through incision and thread hanging therapy. Compared the surgical time, blood loss, surgical cost, wound healing time, and anal function at 6 months after surgery between the two groups of patients. Compared the treatment effects of two groups of patients at 6 months after surgery. Compared the postoperative complications within 6 months and recurrence within 1 year between the two groups. The measurement data subject to normal distribution were expressed by mean ± standard deviation( ± s). The two groups were compared by independent sample t test, and the count data were compared by Chi-square test. Rank sum test was used for comparison of hierarchical data. Results:The surgical time in the observation group was higher than that in the control group [(44.30 ± 8.11) min vs (42.18 ± 7.25) min, ( t=-2.44, P<0.05], and the surgical cost was higher than that in the control group [(1184.81 ± 372.68) yuan vs (835.28 ± 320.03) yuan, t=-8.75, P<0.001]. There was no statistically significant difference in blood loss data between the two groups [(19.57 ± 6.07) mL vs (18.35 ± 5.25) mL, t=-1.88, P>0.05]. The length of wound healing time in the observation group was lower than that in the control group [(24.18 ± 4.35) d vs (29.35 ± 5.08) d, t=11.09, P<0.001]. The anal function score of the observation group at 6 months after surgery was lower than that of the control group [(4.80 ± 1.21) score vs (6.71 ± 1.35) score, t=14.72, P<0.001]. All patients did not experience any loss of follow-up. In the comparison of treatment effects 6 months after surgery, the observation group had a better efficacy rating than control group ( Z=3.86, P<0.001). At 6 months after surgery, the incidence of complications in the observation group was lower than that in the control group [2.30% (2/87) vs 10.34% (9/87), χ2=4.76, P<0.05]. One year after surgery, the recurrence rate in the observation group was lower than that in the control group [2.30% (2/87) vs 10.34% (9/87), χ2=4.76, P<0.05]. Conclusion:The application of incision and thread-drawing selective suture in the treatment of patients with high complex anal fistula is beneficial to the treatment effect of patients, reduces postoperative complications, and protects the anal function of patients, with good use value.

Biomechanical characteristics of retinaculum in the treatment of femoral neck fractures / 中国骨伤

OBJECTIVE@#To investigate the biomechanical characteristics of retinaculum in the treatment of femoral neck fractures.@*METHODS@#The CT data of a 75-year-old female volunteer was processed by software to construct an intact femur model and femoral neck fracture model fixed with three cannulated screws, which were divided into models with retinaculum or not. The Von-Mises stress distribution and displacement were compared to analyze the stability differences between the different models to study the mechanical characteristics of the retinaculum in the treatment of femoral neck fractures.@*RESULTS@#In the intact femur, the most obvious displacement appeared in the weight-bearing area of the femoral head, with retinaculum 0.381 37 mm, and without retinaculum 0.381 68 mm. The most concentrated part of the Von-Mises stress distribution was located in the medial and inferior part of the femoral neck, with retinaculum 11.80 MPa, without retinaculum 11.91 MPa. In the femoral neck fracture fixed with three cannulated screws model, the most obvious position of displacement also appeared in the weight-bearing area of the femoral head, with retinaculum 0.457 27 mm, without retinaculum 0.458 63 mm. The most concentrated part of the Von-Mises located at the medical and inferior part of the femoral neck, with retinaculum 59.22 MPa, without retinaculum 59.14 MPa. For the cannulated screws, the Von-Mises force peaks all appeared in the posterior and superior screw, with retinaculum 107.48 MPa, without retinaculum 110.84 MPa. Among the three screws, the Von-Mises stress of the anterior-superior screw was the smallest, which was 67.88 MPa vs 68.76 MPa in the retinaculum and non-retinaculum groups, respectively.@*CONCLUSION@#The complete retinaculum has little effect on the stability of intact femur and femoral neck fractures with anatomical reduction after internal fixation, and cannot effectively improve the stability of the fracture end after the fracture.

Surgical treatment for ipsilateral femoral neck and shaft fracture / 中国骨伤

OBJECTIVE@#To retrospectively analyze efficacy of single structure internal fixation and double structure internal fixation in the treatment of ipsilateral femoral shaft and neck fracture, and analyze their indications.@*METHODS@#From June 2015 to December 2020, 21 patients with ipsilateral femoral shaft and femoral neck fracture were treated, including 14 males and 7 females, aged 23 to 69 years old with an average of(38.1±12.9) years old. According to different femoral shaft fracture sites, some patients were fixed with cephalomedullary implant for both femoral neck and the femoral shaft(single structure, InterTan or PFNA Ⅱ), some patients were fixed with cannulated screws for the femoral neck and a retrograde locking nail for the femoral shaft (dual structure), and postoperative function and complications were recorded during follow-up. In 10 cases of single-structure fixation, the femoral necks were all basicervical fractures, and the femoral shaft fractures were located in the proximal isthmus;11 cases were double-structure fixation, 9 cases in 11 were basal type of femoral neck, 2 cases in 11 were neck type, and the femoral shaft fractures were located in the isthmus and the distal isthmus.@*RESULTS@#All patients were followed up for 12 to 27 months. No femoral head necrosis, deformity, delay or nonunion occurred in the patients with single-structure fixation, and no delayed union or nonunion occurred in femoral shaft fractures;At the final follow-up, Harris score of patients with single-structure fixation was 91.8±4.1, with 8 cases were excellent and 2 cases were good. The fractures of patients with dual-structure fixation achieved good union without femoral head necrosis, except 1 case of femoral shaft fracture had delayed union;At the final follow-up, Harris score of patients with dual-structure fixation was 92.4±5.9, 7 cases were excellent, 3 cases were good, and 1 case was fair.@*CONCLUSION@#Good reduction and fixation is the key to the treatment of such fractures. Both the single-structure fixation and the dual-structure fixation are good methods, and it should be selected according to the locations of femoral shaft and femoral neck fractures. Single-structure fixation is a good choice for femoral shaft fractures located at the proximal isthmus and basal femoral neck fractures. For isthmus and distal femoral shaft fractures combined with ipsilateral femoral neck fractures, dual-structure fixation is recommended.

Therapeutic effect of human umbilical cord mesenchymal stem cells on imiquimod-induced psoriasis-like mouse models / 中华皮肤科杂志

Objective:To investigate the therapeutic effect of human umbilical cord mesenchymal stem cells (MSCs) on psoriasis-like mouse models induced by imiquimod and the underlying mechanisms.Methods:Eighteen C57BL/6 mice were randomly and equally divided into vaseline group, model group and treatment group according to a random number table. The mice in the model group and treatment group received topical treatment with 5% imiquimod cream at a dose of 62.5 mg once a day for 6 consecutive days on the shaved back, and those in the vaseline group received the treatment with the same amount of vaseline ointment; the mice in the treatment group were injected with 1.5×10 6 human umbilical cord MSCs via the caudal vein on days 1 and 4. The severity of skin lesions on the back of the mice was assessed everyday according to the psoriasis area and severity index (PASI) . Twenty-four hours after the last treatment, that is, on day 7, blood samples were taken, and the mice were sacrificed. The dorsal skin tissues were resected and subjected to hematoxylin and eosin (HE) staining. A single cell suspension of the resected spleen was prepared, and flow cytometry was performed to detect the Th1 and Th17 cell subsets in the spleen cells. Enzyme-linked immunosorbent assay was conducted to detect serum levels of cytokines interleukin (IL) -17A and tumor necrosis factor (TNF) -α. One-way analysis of variance was used for comparisons among groups, Tukey test for multiple comparisons, and repeated measures analysis of variance for the analysis of changes in the PASI score over time. Results:On day 7, there was obvious scaly erythema on the back of the mice in the model group, and the skin thickness and number of infiltrating inflammatory cells were significantly higher in the model group (78.73 ± 23.11 μm, 36.16 ± 2.95 cells/mm 2) than in the vaseline group (13.28 ± 4.57 μm, 13.33 ± 1.15 cells/mm 2, q=19.25, 7.21, respectively, both P < 0.001) . The treatment group showed significantly decreased PASI score, epidermal thickness and number of infiltrating inflammatory cells compared with the model group (all P < 0.001) . The percentage of Th17 cell subsets in the spleen cells and serum level of TNF-α were significantly lower in the treatment group than in the model group (both P < 0.05) . There were no significant differences in the spleen weight, spleen index, spleen cell count, Th1 cell percentage or serum IL-17A level between the treatment group and the model group (all P>0.05) . Conclusion:Human umbilical cord MSCs can effectively alleviate skin inflammation induced by imiquimod in the psoriasis-like mouse models, likely by inhibiting Th17 cell formation and TNF-α expression.

Performance of reflectance confocal microscopy in localization diagnosis of and monitoring of therapeutic efficacy in early-stage mycosis fungoides / 中华皮肤科杂志

Objective:To analyze consistency between histopathological and reflectance confocal microscopy (RCM) characteristics of early-stage mycosis fungoides (MF) , and to evaluate the value of RCM in assisting the pathological diagnosis of early-stage MF and the feasibility of dynamic monitoring of treatment response with RCM.Methods:From January 2014 to January 2018, 40 cases of clinically suspected MF were collected from Department of Dermatology, Third People′s Hospital of Hangzhou, including 26 males and 14 females, and their age was 47.0 ± 17.6 years. According to the summarized RCM characteristics of early-stage MF, biopsy sites were preliminarily located, and then a histopathological examination was performed. The RCM and pathological features of MF were compared. In addition, a combination therapy with narrowband ultraviolet B and interferon was performed in patients with confirmed MF. Targeted lesions were followed up with RCM for 9 months, and then therapeutic efficacy was evaluated.Results:Among the 40 cases of clinically suspected MF, 8 were preliminarily diagnosed as typical MF, 18 as suspected MF, and 14 were excluded according to the RCM characteristics; according to the pathological features, 12 could be diagnosed as typical MF, 14 as suspected MF, and 14 were excluded. Consistency analysis showed that the kappa coefficient between RCM classification and pathological diagnosis was 0.848 ( P < 0.01) . The consistency of epidermal infiltration of mildly refractive cells was the highest between RCM and pathological findings (kappa coefficient = 1, P = 0.005) , followed by dermal fibrosis at the erythema stage (kappa coefficient = 0.714, P = 0.035) . The RCM characteristics of MF gradually returned to normal during treatment, but atypical lymphocytes still existed when clinical lesions completely regressed. Conclusion:RCM can be used for pathological localization of suspected MF lesions in the early stage, and for dynamic monitoring of therapeutic efficacy in MF.

The protective effect of spironolactone on myocardial injury in septic rats / 中华急诊医学杂志

Objective:To investigate the protective effect of spironolactone on myocardial injury in septic rats and to provide a novel measure for the diagnosis and treatment of sepsis myocardial injury.Methods:Totally 120 male Sprague-Dawley rats were randomly divided into the sham group, cecal ligation and perforation group (CLP group), and spironolactone group. The sham group was only exposed to the cecum by laparotomy. CLP was performed to induce sepsis in the CLP group and spironolactone group. The cecal perforation was ligated and the contents of the intestine were squeezed out. The spironolactone group was administered spironolactone by gavage with a dose of 20 mg/(kg·d) per rat. The sham and CLP groups were given the same dose of saline. The experiment period was 7 days. After the rats were sacrificed, blood was collected and myocardial tissue was removed. The changes of serum TNF-α, IL-6, cTnI and CK-MB levels were detected by ELISA. Cardiac structure and function were detected by echocardiography. The relative apoptosis of left ventricular myocytes in rats was detected by TUNEL staining. The levels of TNF-α, IL-6, Bcl2-associated X protein (Bax), B cell lymphoma 2 (Bcl2) and Caspase 3 in the left ventricle tissue were detected by immunohistochemistry.Results:Compared with the CLP group, the levels of TNF-α and IL-6 in serum and left ventricular tissue were significantly decreased ( P<0.05) and serum levels of cTnI and CK-MB were significantly down-regulated ( P<0.05). Heart rate (HR) and left ventricular diastolic dimension (LVDd) were significantly reduced ( P<0.05), and ejection fraction (EF) and left ventricular fractional shortening (FS) increased significantly ( P<0.05). Ventricular muscle apoptosis was improved ( P<0.05),the level of apoptosis-related protein Bcl2 was increased and the Bax and Caspase3 expression were significantly down-regulated ( P<0.05).The expression of Bcl2 protein, EF and FS in the CLP group were significantly lower than those in the sham group( P<0.05), and the remaining indexes were significantly higher than those in the sham group( P<0.05). Conclusions:Spironolactone can treat sepsis-induced myocardial injury by reducing inflammatory response caused by sepsis, reducing myocardial damage, alleviating ventricular muscle apoptosis, and improving ventricular structure and function.

Persistence and clearance of viral RNA in 2019 novel coronavirus disease rehabilitation patients / 中华医学杂志(英文版)

Background@#A patient’s infectivity is determined by the presence of the virus in different body fluids, secretions, and excreta. The persistence and clearance of viral RNA from different specimens of patients with 2019 novel coronavirus disease (COVID-19) remain unclear. This study analyzed the clearance time and factors influencing 2019 novel coronavirus (2019-nCoV) RNA in different samples from patients with COVID-19, providing further evidence to improve the management of patients during convalescence.@*Methods@#The clinical data and laboratory test results of convalescent patients with COVID-19 who were admitted to from January 20, 2020 to February 10, 2020 were collected retrospectively. The reverse transcription polymerase chain reaction (RT-PCR) results for patients’ oropharyngeal swab, stool, urine, and serum samples were collected and analyzed. Convalescent patients refer to recovered non-febrile patients without respiratory symptoms who had two successive (minimum 24 h sampling interval) negative RT-PCR results for viral RNA from oropharyngeal swabs. The effects of cluster of differentiation 4 (CD4)+ T lymphocytes, inflammatory indicators, and glucocorticoid treatment on viral nucleic acid clearance were analyzed.@*Results@#In the 292 confirmed cases, 66 patients recovered after treatment and were included in our study. In total, 28 (42.4%) women and 38 men (57.6%) with a median age of 44.0 (34.0–62.0) years were analyzed. After in-hospital treatment, patients’ inflammatory indicators decreased with improved clinical condition. The median time from the onset of symptoms to first negative RT-PCR results for oropharyngeal swabs in convalescent patients was 9.5 (6.0–11.0) days. By February 10, 2020, 11 convalescent patients (16.7%) still tested positive for viral RNA from stool specimens and the other 55 patients’ stool specimens were negative for 2019-nCoV following a median duration of 11.0 (9.0–16.0) days after symptom onset. Among these 55 patients, 43 had a longer duration until stool specimens were negative for viral RNA than for throat swabs, with a median delay of 2.0 (1.0–4.0) days. Results for only four (6.9%) urine samples were positive for viral nucleic acid out of 58 cases; viral RNA was still present in three patients’ urine specimens after throat swabs were negative. Using a multiple linear regression model (F=2.669, P=0.044, and adjusted R2=0.122), the analysis showed that the CD4+ T lymphocyte count may help predict the duration of viral RNA detection in patients’ stools (t=-2.699, P=0.010). The duration of viral RNA detection from oropharyngeal swabs and fecal samples in the glucocorticoid treatment group was longer than that in the non-glucocorticoid treatment group (15 days vs 8.0 days, respectively; t=2.550, P=0.013) and the duration of viral RNA detection in fecal samples in the glucocorticoid treatment group was longer than that in the non-glucocorticoid treatment group (20 days vs 11 days, respectively; t=4.631, P <0.001). There was no statistically significant difference in inflammatory indicators between patients with positive fecal viral RNA test results and those with negative results (P >0.05).@*Conclusions@#In brief, as the clearance of viral RNA in patients’ stools was delayed compared to that in oropharyngeal swabs, it is important to identify viral RNA in feces during convalescence. Because of the delayed clearance of viral RNA in the glucocorticoid treatment group, glucocorticoids are not recommended in the treatment of COVID-19, especially for mild disease. The duration of RNA detection may relate to host cell immunity.

Heterotopic ossification after arthroscopy for hip impingement syndrome / 中华医学杂志(英文版)

BACKGROUND@#Heterotopic ossification (HO) is a known complication of hip arthroscopy. We investigated incidence of HO after hip arthroscopy and determined whether revision for HO improved outcome.@*METHODS@#A retrospective study was conducted on 242 patients (140 men and 102 women, mean age: 36.2 ± 9.5 years) who underwent hip arthroscopy for femoroacetabular impingement (FAI) between January 2016 and January 2018. The average follow-up period was 22.88 ± 11.74 months (range: 11-34 months). Thirteen (5.37%) cases of HO (six men and seven women, five left hips and eight right hips; mean age: 37.5 ± 4.7 years) were observed. Among them, four cases with HO with obvious pain symptoms and persistent non-remission underwent revision surgery to remove HO. Monthly follow-up was conducted. Visual analog scale (VAS), modified Harris Hip Score (mHHS), and non-Arthritis Hip Score (NAHS) were evaluated and compared between HO and non-HO patients. Independent sample t test, Mann-Whitney U test and the Chi-square test were used for inter-group comparisons. HO degree was evaluated using Brooker classification. Symptoms and function were evaluated before and after revision.@*RESULTS@#A total of 242 patients were involved in this study. Thirteen cases (5.4%) had imaging evidence of HO. Nine (9/13) were classified as Brooker stage I, three (3/13) Brooker stage II, and one (1/13) Brooker stage III. HO was detected by ultrasonography as early as 3 weeks after operation. After primary surgery, the mHHS of the HO group and non-HO group increased by 13.00 (8.50, 25.50) and 24.00 (14.00, 34.50) points (Z = -1.80, P = 0.08), NAHS increased by 18.00 (9.50, 31.50) and 26.00 (13.50, 36.00) points (Z = -1.34, P = 0.18), and VAS decreased by 3.00 (2.00, 4.00) and 4.00 (3.00, 4.50) points (Z = -1.55, P = 0.12). Average follow-up time after revision was 9.00 ± 2.94 months; mHHS increased by 34.75 points (t = -55.23, P < 0.01) and NAHS by 28.75 points (t = -6.03, P < 0.01), and VAS decreased by 4 points (t = 9.80, P < 0.01). HO and non-HO patients were similar for demographic and surgical data, and clinical and functional scores.@*CONCLUSION@#HO incidence after arthroscopic treatment of FAI is similar to that found in previous studies. Most HO have no effect on clinical symptoms. Patients who undergo revision HO resection show improvement in pain and joint function.

Bone marrow mesenchymal stem cells versus bone marrow mononuclear cells for treating cerebral palsy / 中国组织工程研究

BACKGROUND: Bone marrow mesenchymal stem cells (BMSCs) and bone marrow mononuclear cells(BMMNCs) have been both used to treat spastic cerebral palsy. However, the differences in their therapeutic effects remain unknown. OBJECTIVE: To compare the therapeutic effects of BMMSCs and BMMNCs in cerebral palsy children as well as on fine motor function. METHODS: 105 children with spastic cerebral palsy were enrolled and randomly assigned to three groups: BMMSCs group, BMMNCs group and control group. Patients in the two transplantation groups received four intrathecal cell injections, and those in the control group received Bobath therapy, twice a day, for consecutive 3 weeks. The Gross Motor Function Measure (GMFM) and Fine Motor Function Measure (FMFM) were used to evaluate the therapeutic efficacy at 3, 6 and 12 months after transplantation. RESULTS AND CONCLUSION: At 3 months after cell transplantation, scores in A dimension of GMFM and in A, C dimensions of FMFM in BMMSC group were all superior to those of BMMNC group and control group (P < 0.05). At 6 months after cell transplantation, scores in A, B dimensions of GMFM and in A, B, C, D and E dimensions of FMFM in BMMSC group were better than those of BMMNC group and control group (P< 0.05), and total scores of GMFM and FMFM were also better in the BMMSC group (P < 0.05). At 12 months after cell transplantation, scores in A, B and C dimensions of GMFM and A, B, C, D and E dimensions of FMFM scores in BMMSC group were all superior to those of BMMNC group and control group (P < 0.05) as well as the total GMFM and FMFM scores. There were six cases of low intracranial pressure headache in BMMNC group and six cases of low-grade fever in BMMSC group. In summary, both BMMSCs transplantation and BMMNCs transplantation are safe, effective and feasible for the treatment of spastic cerebral palsy in children, and moreover, BMMSCs transplantation is a better method than BMMNCs transplantation to improve gross and fine motor functions of spastic cerebral palsy children.

Objective To evaluate imaging features of verruca plana by dermoscopy and reflectance confocal microscopy (RCM).Methods Totally,88 untreated patients with verruca plana were enrolled into this study.One typical skin lesion was chosen from each patient and subjected to dermoscopy and RCM separately,and imaging features were recorded and analyzed.Results Dermoscopy revealed a light red background in 48 cases (54.55％),a light yellow background in 40 cases (45.45％),and a various number of punctate hemorrhages in 84 cases (95.45％).RCM showed concentric onion-skin-like structures in 48 patients (54.55％).Among 57 patients with disease duration ＞ 1 year,44 (77.19％) had the concentric onion-skin-like pattern,while only 4 (12.90％) patients had similar structures among 31 patients with disease duration ＜ 1 year.A significant difference in the prevalence of concentric onion-skin-like structures was observed between patients with disease duration ＞ 1 year and those with disease duration ＜ 1 year (x2 =33.47,P ＜ 0.05).Of 88 patients,86 (97.73％) had hyperpigmentation in the basal layer at the dermo-epidermal junction,intact dermal papillary rings,vasodilatation,hyperemia and 1-2 dilated capillaries in the dermal papillae.Eight patients were treated for 2 weeks,and the above features disappeared after the treatment under dermoscopy and RCM.Conclusion Based on clinical manifestations,dermoscopy and RCM features may be helpful for the diagnosis of verruca plana.

Benign ovarian cystic lesions: CT and MRI findings / 实用放射学杂志

Objective To study the CT and MRI features of benign ovarian cystic lesions (BOCL) and to improve the understanding of imaging features.Methods CT and MRI findings were retrospectively reviewed and analyzed in 48 patients with BOCL proved by surgical pathology.CT scan was performed in 35 cases, among which 20 cases were performed with CT enhancement scan;MRI scan was performed in 8 cases, among which 3 cases were performed with MRI enhancement scan and diffusion weighted imaging(DWI).Five cases were performed with both CT and MRI.Results There were 11 cysts (3 simple cysts, 3 corpus luteum cyst, and 5 endometriotic cyst), 10 serous cystadenomas with 13 lesions, 8 mucinous cystadenomas, 9 teratomas with 10 lesions, and 10 struma ovarii.The CT and MRI characteristics of the lesions in size, shape,thickness of cyst wall,wall nodule,density or signal intensity,and enhancement features were helpful in differential diagnosis of BOCL.Conclusion CT and MRI findings of BOCL have certain characteristics, which is significant in the diagnosis, preoperative evaluation and prognosis.

Clinical significance of combined detection of RF,anti-CCP antibody,GPI and anti-RA3 3 antibody in rheumatoid arthritis / 国际检验医学杂志

Objective To investigate the diagnostic significance of combined detection of rheumatoid factor (RF),anti-cyclic cit-rullinated antibody (anti-CCP antibody),glucose-6-phosphatase (GPI)and anti-RA33 antibody in rheumatoid arthritis (RA).Meth-ods One hundred and twenty-six patients with RA,60 patients with other autoimmune diseases and 60 healthy subjects undergoing physical examination were selected as the research subjects.The singled detection of RF,anti-CCP antibody,GPI and anti-RA33 an-tibody,and their combined detection were used to analyze their roles in RA diagnosis.Results Compared with the healthy control group,the four indexes in the RA group were increased,the difference was statistically significant (P<0.05),the RF level in the autoimmune diseases group was increased compared with the control group,the difference was statistically significant(P<0.05). Compared with the the autoimmune diseases group,the four indexes in the RA group were increased,the difference was statistically significant (P<0.05).The sensitivity and specificity of RF to RA were 77.77% and 63.33%;the sensitivity and specificity of anti-CCP antibody to RA were 69.04% and 95.00%;the sensitivity and specificity of GPI antibody to RA were 25.40% and 100.00%;the sensitivity and specificity of anti-RA33 antibody were 27.77% and 99.16%,respectively.The specificity of combined 2 indica-tors was increased from 63.33% to 85.00%,which of combined 3 indicators was increased to 93.33% and which of combined 4 in-dicators even reached to 100.00%.Conclusion The combination of RF,anti-CCP antibody,GPI and anti-RA33 antibody indicators greatly increases with the sensitivity and specificity for diagnosing RA and has clinical significance.

Effect of motivational interviewing combined with peer participation on obesity management in adolescents / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To investigate the effect of motivational interviewing combined with peer participation on obesity management in adolescents.</p><p><b>METHODS</b>A total of 100 adolescents with simple obesity were randomly divided into traditional management and peer participation groups (n=50 each). The traditional management group received traditional health management. The peer participation group received motivational interviewing performed by psychological consultants combined with peer participation through the entire process in addition to traditional health management. The physical exercise, dietary behavior, differences in body composition parameters, and effect of comprehensive intervention were compared between the two groups after intervention for half a year.</p><p><b>RESULTS</b>After the health management for six months, the peer participation group showed better improvements in the control of energy intake, adjustment of dietary structure, adherence to moderate/high intensity exercise, and increase in lean body mass compared with the traditional management group (P<0.05). The peer participation group had a significantly higher attendance rate for guidance and counseling performed by a multidisciplinary team once a week than the traditional management group (89% vs 57%; P<0.05), as well as a significantly higher response rate to health management than the traditional management group (83% vs 43%; P<0.05).</p><p><b>CONCLUSIONS</b>Motivational interviewing combined with peer participation for obesity management can improve the compliance and the effect of comprehensive intervention in losing weight in adolescents.</p>

Do Cigarette Smoking and Obesity Affect Semen Abnormality in Idiopathic Infertile Males?

PURPOSE: This study was conducted to find the relative risk of semen abnormality with respect to smoking history and obesity. MATERIALS AND METHODS: Subfertile or infertile men were enrolled in this study from July 2010 to June 2011. All participants provided their cigarette use information, self-reported weight, height, semen analysis, physical examination, and sexually transmitted disease status. None of the enrolled patients had any specific pathological reason for infertility. Semen abnormality was defined as a condition in which one or more parameters did not satisfy the World Health Organization's criteria. RESULTS: A total of 1,073 male patients were considered for this study. After the application of the inclusion criteria, 193 patients were finally analyzed. These patients were divided into two groups according to semen abnormality: the normal semen group (n=72) and the abnormal semen group (n=121). Baseline characteristics, except age and smoking history, were not significantly different between the two groups. Smoking history and age were risk factors for the semen abnormality of idiopathic infertile male patients. CONCLUSIONS: Smoking and old age were risk factors for semen abnormality. However, obesity did not affect the semen abnormality. Smoking affected semen quality and is therefore expected to play a negative role in conception.
