Objective To investigate the effect of tongue tie corrective surgery on the development of language in children with short lingual frenulum.Methods 94 children with short lingual frenulum were selected,and under the permission of the patients'family they were randomly divided into two groups.The treatment group received ankylotomy and language training.The control group was only given language training.The clinical efficacy,improvement time of pronunciation and adverse reactions were compared between the two groups.Results The total effective rate of the treatment group was 91.49％,which was significantly higher than 72.34％ of the control group (x2 =5.816,P ＜0.05).The improvement time of pronunciation in the treatment group was significantly shorter than the control group(t =21.250,P ＜ 0.01).There were no serious adverse reactions observed in two groups.Conclusion Tongue tie correction surgery can significantly affect the language development in children with short lingual frenulum,the improvement time of pronunciation is short,which is worthy of clinical application.

Objective To investigate the significance of anti-mutated citrullinated vimentin(MCV)an- tibody in rheumatoid arthritis(RA)and study the correlation among anti-CCP,other antoantibodies and clinical manifestations of RA.Methods Anti-MCV antibody was detected by enzyme-linked immunosorbent assay (ELISA)in 166 serum samples including 74 from RA(18 cases with early RA and 56 cases with late RA),50 from non-RA rheumatic diseases and 42 cases of healthy blood donors.At the same time,other antuoantibod- ies were detected by different techniques,and their clinical meaning was investigated with the corresponding clinical data.Results Anti-MCV was found in 78%(58/74)of RA.The sensitivity and specificity of Anti- MCV in RA were 78% and 95%.The positive and negative predictive value was 97% and 71%.The average cut off concentration of Anti-MCV was(552?380)U/ml in RA,(162?63)U/ml in non-RA and(63?46)U/ml in healthy control.Anti-MCV was strongly correlated to anti-CCP(r=0.502,P=0.000),then AKA(r=0.408)anti APF(r=0.369).No differences was found between Anti-MCV and other clinical/laboratory parameters(P＞0.05). Conclusion Anti-MCV antibody may be a valuable diagnostic parameter for RA.Anti-MCV is more strongly correlated to anti-CCP than APE and AKA.It may not relate to disease activity and/or severity.

To assess the correlation between thyroid function and glucolipid metabolism in type 1 diabetic adults. A retrospective analysis was conducted in 230 type 1 diabetic adults who were hospitalized in the Department of Endocrinology of Shandong Provincial Hospital Affiliated to Shandong University from January 2008 to January 2020. It showed that thyroid stimulating hormone(TSH) was significantly positively correlated with total cholesterol (TC) ( r=0.239), triglycerides (TG) ( r=0.166) and low-density lipoprotein cholesterol (LDL-C) ( r=0.249), respectively (all P<0.05). Free triiodothyronine (FT 3) was significantly negatively correlated with fasting plasma glucose (FPG) ( r=-0.272), glycated hemoglobin (HbA1c) ( r=-0.240), TC ( r=-0.197) and LDL-C ( r=-0.220), respectively (all P<0.05). Free thyroxine (FT 4) was negatively correlated with TC ( r=-0.171) and LDL-C ( r=-0.170), respectively (all P<0.05). TC was an independent predictor of TSH, FT 3 and FT 4, FT 3 and FT 4 were independent predictors of HbA1c. TSH was an independent predictor of TC, TG and LDL-C. Thyroid function is closely related to glucolipid metabolism in type 1 diabetic adults.

OBJECTIVETo evaluate the effect and complications of transurethral plasmakinetic prostatectomy (TUPKP) in the treatment of benign prostatic hyperplasia (BPH).

METHODSAll 313 patients underwent TUPKP, and the operative indexes and perioperative blood indexes were recorded. After operation, 290, 288 and 142 cases of BPH were followed up at 1 month, 3 months and 1 year respectively. Qmax, IPSS and QOL were measured in all the catamneses.

RESULTSThe operative time was (51 +/- 22) min; the mount of blood loss was (66 +/- 60) ml; no TURS occurred in any cases. The mean catheterization time was (11 +/- 10) h and the mean postoperative stay was (3.6 +/- 1.3) d. Qmax increased from (9.0 +/- 4.4) ml/s to (20.5 +/- 7.1) ml/s at 1 month, (21.8 +/- 5.4) ml/s at 3 months and (21.4 +/- 6.6) ml/s at 1 year after operation (P < 0.01). Correspondingly, IPSS decreased from (26.2 +/- 5.1) score to (6.0 +/- 9.0) score, (5.6 +/- 0.8) score and (4.4 +/- 2.7) score (P < 0.01), and the QOL of all the catamneses significantly improved.

CONCLUSIONTUPKP, a safe and effective method with fewer complications, can be recommended for the treatment of BPH.

Objective:To explore the effects of myosteatosis and blood glucose (BG) on postoperative complications in non-diabetic gastric cancer patients receiving supplemental parenteral nutrition (SPN) after gastrectomy.Methods:Patients who underwent radical gastrectomy between March 2017 and June 2021 in the Department of Surgical Oncology, the First Hospital of Lanzhou University were included in this study. Various preoperative inflammatory and nutritional indicators, including skeletal muscle metrics at the third lumbar level on CT, were collected retrospectively. Postoperative BG within 3 days and complications within 30 days were monitored. Patients were divided into two groups according to the presence or absence of myosteatosis (assessed via skeletal muscle density [SMD]) and the differences in postoperative BG and complication incidence were compared. Mediation model was used to analyze the mediating effect of BG in the association between SMD and postoperative complications.Results:A total of 357 patients were included in the study. Compared with the 299(83.8%) patients without myosteatosis , the incidence of hyperglycemia, mean BG, maximal BG, and BG fluctuation while on SPN in the 58(16.2%) patients with myosteatosis were higher, and the comprehensive complication index (CCI) and the incidence of complication were higher ( P<0.05). More importantly, BG showed the mediation effect of -0.0892 in the effect of SMD on CCI ( P<0.05), with the effect size of 19.3％. Conclusion:Myosteatosis and postoperative hyperglycemia are associated with higher incidence of complications, and BG plays an intermediary role in the association between myosteatosis and CCI.

OBJECTIVETo investigate the value of Diffusion-Weighted Imaging (DWI) in the diagnosis of early stage liver diffuse lesions.

METHODSDiethylnitrosamine (DEN) was used to induce liver lesions in rats. Sequential DWI studies were performed on the livers from 1 to 14 weeks after DEN was administered through drinking water. Comparing studies with a blank control group was set and pathohistological examinations of the livers were performed.

RESULTSNo obvious routine MRI morphological change was found in either group during this period, but DWI demonstrated heterogeneous changes in the test group at the cirrhosis stage. There was no significant alteration of the apparent diffusion coefficient (ADC) value in the control group during this period (P > 0.05). The ADC values of the test group began to decline from the fifth week. Until the tenth week, the ADC value of the test group decreased drastically and when b = 300 s/mm2 statistic, the results showed an obvious difference between the two groups. There were also differences between the ADC values at the 10th, the 9th and the 1st weeks of the test group (P < 0.05). When b = 600 s/mm2 and 1000 s/mm2, significant differences were found after the sixth week between the two groups (P < 0.01). The main pathohistological liver change in the test group during the 1 to 4 week period after DEN was administered was swelling of hepatocytes; during the 5 to 8 week period it was fibrous tissues hyperplasia, and in the 9 to 14 week period it was cirrhotic nodule formation.

CONCLUSIONMR functional DWI could detect liver diffuse lesions earlier than conventional MR imaging. Measurement of ADC value may be of use in early diagnosis of liver diffuse diseases and for monitoring the changes of the lesions.

OBJECTIVE: To study expression of inducible nitric oxide synthase (iNOS) in oral squamous cell carcinomas (OSCC) and its relations to microvessel density (MVD) and lymphatic metastasis. METHODS: With 9 cases of normal oral mucosa as control, the expression rate of iNOS in 41 cases of OSCC was evaluated by immunohistochemstry SP staining. With CD34 as label, MVDs of these cases were also detected. RESULTS: The iNOS expression rate of OSCC cases was 63.41%(26/41), while no positive expression was seen in 9 cases of normal oral mucosa. Anymore, the expression rate of N+ group was 85.00% while that of N group 42.90%, the rate between them was significantly different (P<0.01). There was correlation between MVD and lymphatic metastasis (rs=0.51, P<0.01). MVDs in groups of different iNOS expression( approximate, equals +++) were 29.667+/-6.945, 34.833+/-4.579, 46.357+/-6.687, 54.167+/-5.565, respectively, and were significantly different with each other (P<0.001). CONCLUSION: There is high expression rate of iNOS in OSCC, and it has close relation to lymphatic metastasis; angiogenesis may facilitate lymphatic metastasis of OSCC, and expression of iNOS has positive relation to MVD in OSCC.

OBJECTIVETo explore the clinical characteristics,diagnosis and treatment of abdominal cocoon.

METHODSClinical data of 203 cases with abdominal cocoon including 7 cases in our hospital and 196 cases reported in Chinese literature from January 1995 to June 2005 were analyzed retrospectively.

RESULTSThe male to female ratio was approximately 1.2:1. The mean age at diagnosis was 33 years. The main clinical manifestations included recurrent acute or chronic intestinal obstruction in 147 cases (72.4%), abdominal mass in 53 cases (26.1%). Of the 203 cases, abdominal plain X-ray were performed in 163, B-ultrasound in 85, CT in 68 and barium meal in 32 cases, however, only 6 cases (3.0%) were diagnosed as abdominal cocoon preoperatively. All the cases received operations included partial or total excision of the membrane and enterolysis in 172 cases (84.7%), together with bowel resection in 34 cases (16.7%) and appendectomy in 51 cases (25.1%). Postoperative complications included recurrent obstruction in 55, and death in 11 cases (5.4%).

CONCLUSIONSThe preoperative diagnosis of abdominal cocoon is difficult. Operations should be performed on the cases with intestine obstruction. Recurrent adhesive intestinal obstruction is the main postoperative complication.
