Objective:To explore an applicative value of a 5-type precise diagnostic technique in integrated precise repair and reconstruction of digit-tip injuries.Methods:From March 2012 to June 2022, 45 digit-tip injuries (38 patients, with an average age of 33 years old) were classified under microscope on the basis of effectiveness of blood vessels remained in the severed tissue. Among the injured digits, there were 15 thumbs, 9 index fingers, 16 middle fingers, 4 ring fingers and 1 little finger. The diagnosis was categorised into 5 types according to involvement of blood vessels: Type I, injury of proper palmar digital artery (10 digits) ; Type II, injury of small artery (5 digits) ; Type Ⅲ, injury of whole vein (4 digits) ; Type IV, injury of superficial palmar arch (4 digits) ; and Type V, vessels missing (22 digits). The timing and therapeutic method of surgery were selected based on the precise classification of 5 types of diagnosis: (1) For type Ⅰ-Ⅳ injuries, 16 patients (23 digits) received in situ tissue replantation after emergency classification. Of which, type Ⅰ-Ⅱ injuries received conventional replantation, type Ⅲ injuries had replantation with arterialised vein, and type IV injuries received replantation with artery-vein shunt. (2) For the type V injuries, 22 patients (22 digits), staged and categorised flap reconstruction with toe flaps were performed. Of which, 7 were performed in emergency surgery, 12 in subemergency surgery and 3 in elective surgery. Based on the severity of defects, small tissue flaps of toe were used in reconstruction of type V injuries and following toe flaps were employed: 9 hallux nail flaps, 3 hallux nail flaps (for reconstruction of distal phalanx), 5 hallux fibular flaps, 3 hallux abdominal flaps and 2 compound tissue flaps with nail bed of the second toe. The sizes of the 45 replanted/transferred tissues flaps were 1.0 cm×0.6 cm×0.4 cm-2.2 cm×1.5 cm×0.8 cm. Donor sites directly sutured. Medical APP was applied in the rehabilitation exercises. Functions of digits were assessed by scheduled follow-ups at outpatient clinic and via remote medical APP to evaluate the clinical efficacy.Results:All small tissue blocks and (or) tissue flaps survived after replantation and (or) flap reconstruction of 45 injured digits. Postoperative follow-up lasted for 6 months to 7 years, with 36 months in average. The appearances of the reconstructed digit-tips were close to normal digits, with TPD at 3-7 mm. According to the Michigan Hand Outcomes Questionnaire (MHQ), 32 patients (37 digits) were in excellent, 5 patients (7 digits) in good, and 1 patient (1 digit) in poor, with 97.78% of excellent and good rate.Conclusion:Five-type precise diagnostic technique is the key to the integrated and precise reconstruction of digit-tip injuries. This method has been clinically validated and achieved realistic recovery from the injured digits.

Objective:To analyze the application effect of condition scale in nursing management of children bronchial asthma in acute attack stage.Methods:A total of 136 children with acute attack of bronchial asthma admitted to Shanxi Children's Hospital from January 2020 to December 2021 were selected by convenience sampling method, and randomly divided into observation group and control group according to random number table method, 68 cases in each group. Children in the observation group received graded nursing intervention based on disease scale, while children in the control group received routine nursing intervention. The first second forced expiratory volume (FEV 1), forced vital capacity (FVC), ratio of FEV l/FVC, peak expiratory flow rate (PEF), medical intervention frequency, the number of ICU transfer and length of stay were compared between the two groups. Results:The results of repeated measurement ANOVA showed that there were intergroup, time and interaction effects on the levels of FEV 1, FVC, FEV 1/FVC and PEF in the two groups, and the differences were statistically significant ( P<0.05). The frequency of medical intervention in observation group was less than that in control group, and the length of hospitalization was shorter, with statistical significance ( P<0.05). There was no significant difference in ICU patients transferred between the two groups ( P>0.05) . Conclusions:Application of Condition Scale in nursing management of children with acute attack of bronchial asthma can improve the lung function of children with acute attack bronchial asthma more effectively, reduce the frequency of medical intervention, shorten the length of hospital stay, and significantly improve the nursing effect.

Objective:To construct a color assessment tool for continuous bladder irrigation (CBI) drainage fluid and to explore its clinical value.Methods:The color assessment tool for CBI drainage fluid (tentative version) was constructed through literature review, expert meetings and practical development, and its consistency was tested and the tool was improved to form a color assessment tool for CBI drainage fluid. Convenience sampling was used to select patients with benign prostatic hyperplasia who underwent transurethral resection of the prostate (TURP) in the First Affiliated Hospital of Soochow University from April to May 2020. According to the assessment method of the tool, the patient's drainage fluid color was evaluated and recorded.Results:The color assessment tool for CBI drainage fluid included 6 color scales, and the corresponding Pantone color card codes were 503C, 3519C, 701C, 702C, 710C, 1807C respectively, and the blood concentration was 0.125%, 0.5%, 1.0%, 2.0%, 4.0% and 8.0% respectively. The tool was used to evaluate the drainage fluid color in 29 patients after TURP. Each evaluation took (5.12±2.41) s; when the color scale was greater than number two, complications such as the bladder spasm and blood clot blockage occurred.Conclusions:The construction method of color assessment tool for CBI drainage fluid is scientific and reliable, which can provide a basis for evaluating the CBI drainage fluid color, and can assist medical and nursing staff to quickly evaluate the drainage fluid color and find abnormal color scales.

Objective: To explore the features of imatinib mesylate (IM) plasma concentration during adjuvant therapy and clinical factors associated with IM plasma concentration in patients with high risk gastrointestinal stromal tumors (GIST), and to determine whether IM plasma concentration <1100 μg/L influences the efficacy of adjuvant therapy. Methods: A retrospective case control study method was used. Case inclusion criteria: (1) complete resection of lesion and GIST confirmed by pathology; (2) high risk classified according to modified National Institutes of Health classification system (2008); (3) administration of IM 400 mg/d for at least 1 month; (4) not taking the medication likely affecting IM pharmacokinetic, such as rifampicin, dilantin, and carbamazepine, within 1 month before blood collection. Data of GIST patients who visited GIST Disease - Oriented Outpatient, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology between January 2015 to December 2018 were retrospectively analyzed. After taking IM for 22-26 hours, 5 ml of peripheral venous blood was collected into EDTA anticoagulant tube. IM plasma concentration was detected by using high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). Patients were divided into <1100 μg/L group and ≥1100 μg/L group according to plasma concentration. Linear regression was used to analyze the relevance between clinical features and IM plasma concentration. Parameters with normal distribution were analyzed by Pearson correlation coefficient, and parameters with non-normal distribution were analyzed by Spearman correlation. Kaplan-Meier survival curves and COX regression model were used for survival analysis. Results: Among the 85 patients enrolled in the study, 49 patients (57.6%) were male and 36 (42.4%) were female, with mean age of (51.9±11.0) years. The body mass index was (22.5±2.9) kg/m² and body surface area was (1.6±0.2) m². Thirty patients received gene test, including 23 patients with c-Kit exon 11 mutation, 4 with c-Kit exon 9 mutation, 1 with c-Kit exon 11 and 17 mutation and 2 without c-Kit or PDGFRA gene mutation. The mean IM plasma concentration was (1391.4±631.3) μg/L, and there were 32 patients with plasma concentration <1100 μg/L and 53 patients with plasma concentration ≥1100 μg/L. There were no statistically significant differences between the two groups in gender, age, body mass index, body surface area, hematological examination (white blood cells, albumin, alanine aminotransferase, aspartate aminotransferase and serum creatinine), tumor location, tumor size, mitotic counts, duration of adjuvant therapy and methods of operation (all P>0.05). Positive correlation between IM plasma concentration and serum creatinine was observed in linear regression analysis (r=0.297, P=0.007), but there were no correlations between IM plasma concentration and age (r=0.044, P=0.686), body mass index (r=0.066, P=0.547), body surface area (r=-0.010, P=0.924), white blood cells (r=-0.080, P=0.478), albumin (r=-0.065, P=0.563), alanine aminotransferase (r=0.114, P=0.308), aspartate aminotransferase (r=0.170, P=0.127) and duration of adjuvant therapy (ρ=0.060, P=0.586). There was no statistically significant difference in IM plasma concentration between patients with different genders (t=0.336, P=0.738) and patients with different surgical methods (F=0.888, P=0.451). Up to March 1, 2019. the median follow-up time was 30 (range 4-49) months. Tumor recurrence was detected in two patients with plasma concentration <1100 μg/L and two with plasma concentration ≥1100 μg/L. One recurrent patient with plasma concentration <1100 μg/L was detected to harbor c-Kit exon 11 and exon 17 mutations, and the other did not receive gene detection. Two recurrent patients with plasma concentration ≥1100 μg/L were both detected to harbor c-Kit exon 9 mutation. The 3-year relapse-free survival rate was 96.4% in the cohort, 96.2% in patients with plasma concentration <1100 μg/L, and 96.6% in patients with plasma concentration ≥1100 μg/L. No significant difference in relapse-free survival was observed between the two groups (P=0.204). Univariate Cox analysis showed that IM plasma concentration <1100 μg/L was not a risk factor for patients with high risk GIST (HR=0.238, 95% CI: 0.022-2.637, P=0.242). Conclusions IM plasma concentration of adjuvant therapy in patients with high risk GIST varies with individual. Patients with higher level of serum creatinine are more likely to have a higher plasma concentration. A blood drug concentration standard of less than 1100 μg/L for advanced GIST patients may not influence the prognosis of patients with high risk GIST.

Objective: To investigate the expression of microRNA-380-5p (miR-380-5p) in cervical cancer tissues and cell lines, and to explore the mechanism of miR-380-5p inhibiting the proliferation and migration of cervical cancer cells. Methods: 16 pairs of cervical cancerous tissues and corresponding para-cancerous tissues were collected from the Department of Obstetrics and Gynecology, the Affiliated Wuhan Central Hospital of Tongji Medical College from December 2016 to July 2017; in addition, cervical cancer cell lines (HCC94, C33A, Hela, SiHa) and human cervical epithelial immortalized H8 cells were also collected for this study. The expression of miR-380-5p in above mentioned tissues and cell lines was detected by Real-time quantitative polymerase chain reaction (qPCR). miR380-5p mimic (experimental group) and miR-NC (negative control group) were transiently transfected into C33A cells by lipofection, and qPCR was used to detect the expression of miR-380-5p in the transfected cells. Cell proliferation and migration were evaluated by cell counting kit (CCK-8) and Transwell assay. Bioinformatics software TargetScan predicted the downstream genes of miR-380-5p, and dual luciferase reporter assay was used to verify the binding of miR-380-5p to the downstream gene RHOA (Ras homolog gene family member A). qPCR and Western blotting were used to detect the expression of miR-380-5p downstream gene-RHOA. Results: The expression level of miR-380-5p in cervical cancer tissues and cell lines was significantly lower than that in para-cancerous tissues and normal cervical epithelial H8 cells (P<0.01); and the expression in C33A cells was the lowest (P<0.01). Compared with the negative control group, the miR-380-5p mimic transfection singnificantly inhibited the proliferation (P<0.05) and migration ability of C33A cells (P<0.01), and down-regulated protein expressions of RHOA, ROCK1, ROCK2, CDK2 and N-cadherin (all P<0.01). Bioinformatics software predicted that RHOA may be a downstream gene of miR-380-5p, and dual luciferase reporter assay proved the specific binding of miR-380-5p to the 3'UTR of RHOA (P<0.01). miR-380-5p could significantly down-regulate RHOA gene expression (P< 0.01). Conclusion: miR-380-5p is low-expressed in cervical cancer cell lines. Over-expression of miR-380-5p may inhibit the proliferation and migration of cervical cancer C33Acells by down-regulating the expression of RHOAgene and its downstream proteins.
