Objective To analyze the changing trends of the incidence and onset age of cervical cancer in Jiangsu Province by using cancer registration data from 2009 to 2019. Methods The information of national cancer registries with continuous data from 2009 to 2019 was selected, and the quality control indices of cancer registration must be up to standards. A total of 16 registries were included in this study. Statistical analysis indicators include the crude incidence rate of cervical cancer, age-standardized incidence rate, actual average onset age, age-standardized average onset age, and average annual percentage change (AAPC). A birth cohort model was constructed to analyze the incidence of cervical cancer among women born from 2009 to 2019 and its incidence trend. Results From 2009 to 2019, the crude and age-standardized incidence rates of cervical cancer among women in Jiangsu Province showed upward trends, with AAPCs of 5.62% (95%CI: 3.47−7.82) and 4.14% (95%CI: 2.06−6.27), respectively. The incidence rate of cervical cancer in rural areas (AAPC=4.46, 95%CI: 1.13−7.91) increased more than that in urban areas (AAPC=3.83, 95%CI: 2.81−4.86). The actual average onset age of cervical cancer increased from 51.53 years in 2009 to 55.07 years in 2019 (β=0.36, P<0.05). The age-standardized average onset age increased from 48.89 years in 2009 to 50.43 years in 2019 (β=0.21, P<0.05). The age composition ratios of cervical cancer in the age group of 60 years and older were 31.90% in 2019 and 22.40% in 2009 (β=3.66, P<0.05). The incidence of cervical cancer in the same age group of people with different birth years showed an upward trend with the increase in birth year. Conclusion From 2009 to 2019, the incidence rate of cervical cancer in Jiangsu Province showed an upward trend, and this trend was more obvious in rural areas than in urban areas. In addition, the average onset age of cervical cancer showed an upward trend.

Objective:To investigate the value of CT imaging radiomics in predicting the therapeutic effect of extracorporeal shock wave lithotripsy (ESWL) for pancreatic duct stones.Methods:The clinical data of 167 patients with pancreatic duct stones treated with ESWL in the Department of Gastroenterology, the First People's Hospital of Hangzhou, Westlake University from July 2016 to January 2023 were retrospectively analyzed. Patients were divided into complete lithotripsy group (stone diameter ≤3 mm, n=94) and incomplete lithotripsy group (stone diameter>3 mm, n=73), according to the size of the largest residual stone after the first ESWL treatment. ITK SNAP software was used to delineate the images of pancreatic duct stones, and the artificial intelligence tool kit developed by United Shadow Company was used to extract the image radiomics characteristics. The pancreatic duct stone data set was randomly assigned into the training set ( n=118) and the test set ( n=29) in the ratio of 8∶2, and the absolute maximum normalization treatment was used, followed by peacekeeping selection through the minimum absolute contraction and selection operator (Lasso) to calculate the CT image radiomics score, and the logistic regression classifier was used to construct the ESWL treatment effect prediction model of pancreatic duct stones. Receiver operating characteristic curves (ROC) were plotted, and the area under the curve (AUC) and sensitivity, specificity, and accuracy were calculated to assess the performance of the prediction model. Decision curve analysis was used to evaluate the clinical value of CT radiomics score in the diagnosis of ESWL for pancreatic duct stones. Results:A total of 2 287 imaging radiomics characteristics were extracted, and 11 optimal imaging radiomics characteristics were finally screened by Lasso regression dimensionality reduction to establish a prediction model for ESWL treatment effect of pancreatic duct stones. The AUC values of the training set and the test set were 0.89 and 0.87, respectively, and the sensitivity, specificity, and accuracy were 82% and 79%, 82% and 82%, 82% and 80%, respectively. The AUC value in the independent validation set was 0.90, and the sensitivity, specificity, and accuracy were 78%, 90%, and 85%, respectively. The results of decision curve analysis showed that when the probability of ESWL efficacy in the diagnosis of pancreatic duct stones with CT image radiomics score was >0.05, the use of CT image radiomics score in the diagnosis of ESWL efficacy in pancreatic duct stones was more beneficial to patients in clinical practice than not.Conclusions:The treatment effect of ESWL for pancreatic duct stones can be predicted by CT imaging radiomics model.

Objective    To explore the feasibility of early chest tube removal following single-direction uniportal video-assisted thoracoscopic surgery (S-UVATS) anatomical lobectomy. Methods    The clinical data of consecutive VATS lobectomy by different surgeons in Xuzhou Central Hospital between May 2019 and February 2022 were retrospectively reviewed. Finally, the data of 1 084 patients were selected for analysis, including 538 males and 546 females, with a mean age of 61.0±10.1 years. These patients were divided into a S-UVATS group with 558 patients and a conventional group (C-UVATS) with 526 patients according to the surgical procedures. The perioperative parameters such as operation time, blood loss were recorded. In addition, we assessed the amount of residual pleural effusion and the probability of secondary thoracentesis when taking 300 mL/d and 450 mL/d as the threshold of chest tube removal. Results    Tumor-negative   surgical margin was achieved without mortality in this cohort. As compared with the C-UVATS group, patients in the S-UVATS group demonstrated significantly shorter operation time (P<0.001), less blood loss (P=0.002), lower rate of conversion to multiple-port VATS or thoracotomy (P=0.003), but more stations and numbers of dissected lymph nodes as well as less suture staplers (P<0.001). Moreover, patients in the S-UVATS demonstrated shorter chest tube duration, less total volume of thoracic drainage and shorter postoperative hospital stay, with statistical differences (P<0.001). After excluding patients of chylothorax and prolonged air leaks>7 d, subgroup analysis was performed. First, assuming that 300 mL/d was the threshold for chest tube removal, as compared with the C-UVATS group, patients in the S-UVATS group would report less residual pleural effusion and less necessitating second thoracentesis with residual pleural effusion>500 mL (P<0.05). Second, assuming that 450 mL/d was the threshold for chest tube removal, as compared with the C-UVATS group, the S-UVATS group would also report less residual pleural effusion and less necessitating second thoracentesis with residual pleural effusion>500 mL (P<0.05). Further multivariable logistic regression analysis indicated that S-UVATS was significantly negatively related to drainage volume>1 000 mL (P<0.05); whereas combined lobectomy, longer operation time, more blood loss and air leakage were independent risk factors correlated with drainage volume>1 000 mL following UVATS lobectomy (P<0.05). Conclusion    The short-term efficacy of S-UVATS lobectomy is significantly better than that of the conventional group, indicating shorter operation time and less chest drainage. However, early chest tube removal with a high threshold of thoracic drainage volume probably increases the risk of secondary thoracentesis due to residual pleural effusion.

Objective    To explore the safety and short-term efficacy of uniportal and three-port video-assisted thoracoscopic surgery (VATS) anatomical segmentectomy for pulmonary nodules. Methods    The clinical data of 225 patients with consecutive VATS anatomic segmentectomy by the same surgeon in Xuzhou Central Hospital between December 2019 and February 2022 was retrospectively reviewed. There were 85 males and 140 females with an average age of 57.3±11.6 years. These patients were divided into an uniportal VATS group (128 patients) and a three-port VATS group (97 patients) according to the surgical procedures. Single-direction anatomical procedure was utilized in the uniportal VATS group. The operation time, blood loss during the surgery, number of dissected lymph nodes, duration and volume of chest drainage, incidence of complications, and postoperative hospital stay of the two groups were compared. Results    There was no conversion to thoracotomy, addition of surgical ports, or mortality in this cohort, with tumor-negative surgical margins. The postoperative pathological staining confirmed 2 (0.9%) patients of lymph node metastasis (pN1) and 4 (1.8%) patients of adenocarcinoma with micropapillary component. As compared with the three-port VATS  group, patients in the uniportal VATS group had shorter operation time (115.6±54.7 min vs. 141.5±62.8 min, P=0.001), less intraoperative blood loss (77.2±49.6 mL vs. 96.9±98.1 mL, P=0.050), less total thoracic drainage [394.0 (258.8, 580.0) mL vs. 530.0 (335.0, 817.5) mL, P=0.010], and shorter postoperative hospital stay (7.7±3.7 d vs. 8.7±3.5 d, P=0.031). Both groups showed similar stations and numbers of dissected lymph nodes, incidence of operation-related complications, duration of chest tube drainage, and the drainage volume in the first and second postoperative days (P>0.05). No tumor recurrence or metastasis was recorded in this cohort during the follow-up of 11 (1-26) months. Conclusion    Single-direction uniportal VATS anatomical segmentectomy is safe and feasible for the treatment of pulmonary nodules, with better short-term efficacy as compared with the three-port VATS procedure, including shorter operation time, less intraoperative blood loss and thoracic drainage. However, further studies are needed to elucidate the precise indications of segmentectomy for lung cancer.

Objective:To investigate the effect of the pedicled pericranial flap in the treatment of chronic cerebrospinal fluid leakage.Methods:A retrospective analysis was conducted based on the clinical data of patients with cerebrospinal fluid leakage after craniocerebral surgery who were admitted to the First People’s Hospital of Yichang from April 2016 to October 2020. The necrotic tissues were thoroughly removed. The dural defects were repaired with pedicled pericranial flaps, and soft tissue defects were repaired with local flaps. The incision was covered with negative pressure closed drainage dressing, and negative pressure was maintained at -50 to -80 mmHg (1 mmHg=0.133 kPa). Cerebrospinal fluid leakage, defect repair, and related complications were observed in postoperative follow-up.Results:A total of five patients (three males and two females, aged 49-65 years) were included. All patients had postoperative composite tissue defects with local infection after craniocerebral surgery, lasting two months to 12 years. The size of the postoperative dural defect ranged from 1.5 cm × 2.0 cm to 2.5 cm × 3.0 cm. The size of the scalp soft tissue defect ranged from 2.0 cm × 2.0 cm to 3.0 cm × 6.0 cm. The size of the pericranial flap ranged from 2.0 cm × 3.0 cm to 3.0 cm × 3.5 cm, and the local flap ranged from 8.0 cm × 13.0 cm to 12.0 cm × 16.0 cm. The cerebrospinal fluid leakage was still observed in one patient at 5 d after the surgery and was treated with continuous lumbar pool puncture for cerebrospinal fluid drainage, which healed one week later. One patient suffered from poor healing of the flap incision, which healed after two weeks of outpatient dressing changing. At the postoperative follow-up of 3 to 17 months, none had any further cerebrospinal fluid leakage, and no other complications such as intracranial infection, loss of frontal lines, scalp numbness, and necrosis occurred.Conclusions:Repair of dural defects by pedicled pericranial flaps can treat chronic cerebrospinal fluid leakage with less damage to the donor site and fewer complications.

BACKGROUND: Endoscopic biopsy can underestimate gastric malignancies as low-grade intraepithelial neoplasia (LGIN). Definitively diagnosed LGIN would progress. This study aimed to evaluate predictive factors to identify malignancies misdiagnosed as LGIN by biopsy and LGIN at high risk of progression. METHODS: The clinical records of patients diagnosed with gastric LGIN by endoscopic biopsy who underwent at least two endoscopies during the first year of follow-up between 2007 and 2017 were retrospectively collected. Three endoscopists reviewed photographs of the initial endoscopy, described lesion characteristics, and made endoscopic diagnoses. Logistic regression was used to analyze predictors to identify malignancies underestimated as LGIN. A receiver operating characteristic curve was used to evaluate the diagnostic accuracy of these predictors. Patient clinical outcomes of follow-up >1 year were collected. Kaplan-Meier estimates with log-rank tests and Cox proportional hazards regression were used to analyze predictors of progression. RESULTS: Overall, 48 of 182 (26.4%) patients were proven to have malignancies. A single lesion, a large lesion size, and marked intestinal metaplasia (IM) were independent predictors of initially misdiagnosed malignancies. The area under the curve of these predictors was 0.871, with a sensitivity of 68.7% and specificity of 92.5%. Twelve of 98 patients (12.2%) progressed during the 33-month median follow-up period. A whitish appearance, irregular margins, marked IM, and histological diagnosis of LGIN more than twice within the first year were predictors for progression. CONCLUSIONS Lesions diagnosed as LGIN by biopsy with marked IM and other predictors above should be prudently treated for high potential to be malignancies or progress. Endoscopic follow-up with repeated biopsies within the first year is recommended.

Objective:To explore the threshold and diagnostic value of Chinese version of the Chelsea Physical Function Assessment Tool (CPAx-Chi) for ICU acquired weakness(ICU-AW).Methods:To learn the details and precautions of the CPAx-Chi scale, and then two researchers used the CPAx-Chi scale and MRC-Score scale to independently evaluate 200 patients who come from a comprehensive ICU in a top first-class hospital in Gansu Province simultaneously. The best cut-off point and value of the CPAx-Chi scale in the diagnosis of ICU-AW were determined by calculating the Receiver Operating Characteristic (ROC) curve, the Youden index(YI) and the consistency test that are all based on the MRC-Score≤48.Results:The ROC Area Under Curve(AUC) of the CPAx-Chi scale diagnosis ICU-AW which based on the MRC-Score≤48 were as follows: ROC AUC of group A was 0.899 (95% CI 0.862-1.025); ROC AUC of group B was 0.874 (95% CI 0.824-0.925). When the best cut-off point of CPAx-Chi scale for diagnosis ICU-AW was 31.5, the maximum YI=0.643, the sensitivity was 87%, and the specificity was 77% in group A; and the maximum YI= 0.62, the sensitivity was 75%, and the specificity was 87% in group B. Meanwhile, when the best cut-off point of CPAx-Chi scale for diagnosis ICU-AW was 30.5, the maximum YI=0.62, the sensitivity was 79%, and the specificity was 83% in group B. Taking the CPAx -Chi≤31 as the best cut-off point, the score differences in ICU-AW group and the non-ICU-AW group were not detected, A group ( F value was 4.53, P=0.035) or B group ( F value was 6.51, P=0.011). The consistency of CPAx -Chi≤31 and MRC-Score≤48 in the diagnosis of ICU-AW was high, and the Kappa=0.845 ( P=0.02) in the group A; the Kappa=0.839( P=0.04) in the group B, and the group differences were detected. Conclusions:CPAx-Chi≤31 is the best cut-off point for diagnosing ICU-AW, and has good sensitivity and specificity. CPAx-Chi scale can be popularized and applied in the critical care medicine in China.

Whole-room calorimeter is one of the gold standards for measuring energy expenditure, which is of great significance in studies on energy metabolism. It can be used to evaluate energy metabolism of different diets, physical activities and lifestyle in healthy or disease states as well as be applied into intervention plan development and efficacy evaluation of nutrition treatment in metabolic diseases, especially in obesity and anti-obesity treatment. It can also play a role in exploring the mechanism of metabolic disease when combined with metabolism related genes and molecular pathways. Here we aim to review the researches on whole-room calorimeter in energy expenditure measurement and obesity.

Objective:To explore the consistency of peripheral whole blood and venous serum procalcitonin (PCT) levels, and the value of peripheral whole blood PCT in evaluating pediatric bacterial infection.Methods:This multicenter cross-sectional parallel control study was conducted in 11 children′s hospital. All the 1 898 patients older than 28 days admitted to these hospitals from March 2018 to February 2019 had their peripheral whole blood and venous serum PCT detected simultaneously with unified equipment, reagent and method. According to the venous serum PCT level, the patients were stratified to subgroups. Analysis of variance and chi-square test were used to compare the demographic characteristics among groups. And the correlation between the peripheral blood and venous serum PCT level was investigated by quantitative Pearson correlation analysis.The PCT resultes were also converted into ranked data to further test the consistency between the two sampling methods by Spearman′s rank correlation test. Furthermore, the ranked data were converted into binary data to evaluate the consistency and investigate the best cut-off of peripheral blood PCT level in predicting bacterial infection.Results:A total of 1 898 valid samples were included (1 098 males, 800 females),age 27.4(12.2,56.7) months. There was a good correlation between PCT values of peripheral whole blood and venous serum ( r=0.97 , P<0.01). The linear regression equation was PCT?venous serum=0.135+0.929×PCT peripheral whole blood. However, when stratified to 5 levels, PCT results showed diverse and unsatisfied consistency between the two sampling methods ( r=0.51-0.92, all P<0.01). But after PCT was converted to ordinal categorical variables, the stratified analysis showed that the coincidence rate of the measured values by the two sampling methods in each boundary area was 84.9%-97.1%. The dichotomous variables also showed a good consistency (coincidence rate 96.8%-99.3%, Youden index 0.82-0.89). According to the severity of disease, the serum PCT value was classified into 4 intervals（<0.5、0.5-<2.0、2.0-<10.0、≥10.0 μg/L）, and the peripheral blood PCT value also showed a good predictive value (AUC value was 0.991 2-0.997 9). The optimal cut points of peripheral whole blood PCT value 0.5、1.0、2.0、10.0 μg/L corresponding to venous serum PCT values were 0.395, 0.595, 1.175 and 3.545 μg/L, respectively. Conclusions:There is a good correlation between peripheral whole blood PCT value and the venous serum PCT value, which means that the peripheral whole blood PCT could facilitate the identification of infection and clinical severity. Besides, the sampling of peripheral whole blood is simple and easy to repeat.
