ABSTRACT
Objective:To investigate the clinical effect of dapagliflozin combined with metformin on type 2 diabetes mellitus (T2DM).Methods:A total of 100 patients with T2DM who received treatment in The Second People's Hospital of Hefei from June 2019 to May 2021 were included in this study. They were randomly divided into a control group ( n = 50) and an experimental group ( n = 50). The control group was treated with metformin, and the experimental group was treated with dagglitazin combined with metformin. All patients were treated for 3 months. Blood glucose index, blood lipid level, and the incidence of adverse reactions were compared between the two groups. Results:After treatment, fasting blood glucose, 2-hour post-prandial blood glucose, and glycosylated hemoglobin in the experimental group were (5.56 ± 0.37) mmol/L, (8.32 ± 0.23) mmol/L, and (6.17 ± 0.26)% respectively, which were significantly lower than (6.96 ± 0.48) mmol/L, (9.58 ± 0.39) mmol/L, and (7.27 ± 0.26)% respectively in the control group ( t = 3.59, 6.92, 5.03, all P < 0.05). The total cholesterol and triglyceride in the experimental group were (3.58 ± 0.53) mmol/L and (1.25±0.26) mmol/L, respectively, which were significantly lower than (4.94 ± 0.58) mmol/L and (1.93 ± 0.18) mmol/L in the control group ( t = 3.16, 4.25, both P < 0.05). There was no significant difference in the incidence of adverse reactions between the two groups ( P > 0.05). Conclusion:Dapagliflozin combined with metformin can effectively control blood glucose and blood lipid in T2DM patients without increasing adverse reactions.
ABSTRACT
Objective:To study the main blood parameters of Leishmania-infected dogs with different clinical symptoms in the high incidence area of visceral leishmaniasis in Gansu Province, and to provide scientific basis for early diagnosis and monitoring of canine leishmaniasis. Methods:In May 2019, Wenxian County of Longnan City and Diebu County of Gannan Tibetan Autonomous Prefecture, the historical endemic areas of visceral leishmaniasis in Gansu Province, were selected as the investigation sites, and 40 dogs with positive Leishmania DNA were investigated. According to their clinical symptoms, they were divided into three groups: asymptomatic ( n = 17), minimally symptomatic ( n = 12) and symptomatic ( n = 11). At the same time, 10 healthy dogs were selected as controls. Major blood indexes were detected by an automatic animal blood five-classification cell analyzer. Results:Compared with the control group, the number of red blood cells, hemoglobin content, hematocrit, and the number of lymphocytes, monocytes and eosinophils in the asymptomatic, minimally symptomatic and symptomatic groups were decreased ( P < 0.05), while the number of white blood cells and neutrophils in minimally symptomatic and symptomatic groups were decreased ( P < 0.05). The above blood indexes were lower in the symptomatic group than those in the asymptomatic group. The number of red blood cells (control group vs symptomatic group) decreased from (6.82 ± 0.05) × 10 12/L to (4.19 ± 0.08) × 10 12/L, hemoglobin content decreased from (15.84 ± 0.74) g/L to (9.65 ± 0.18) g/L, hematocrit decreased from (46.41 ± 0.95)% to (27.86 ± 0.42)%, the number of white blood cells decreased from (14.90 ± 0.22) × 10 9/L to (10.23 ± 0.24) × 10 9/L, the number of neutrophils decreased from (7.25 ± 0.18) × 10 9/L to (6.18 ± 0.11) × 10 9/L, the number of lymphocytes decreased from (2.80 ± 0.07) × 10 9/L to (1.64 ± 0.06) × 10 9/L, the number of monocytes decreased from (1.13 ± 0.01) × 10 9/L to (0.53 ± 0.02) × 10 9/L, and the number of eosinophils decreased from (1.70 ± 0.06) × 10 9/L to (0.71 ± 0.03) × 10 9/L. Conclusion:Different clinical symptoms of Leishmania-infected dogs have different blood test results.
ABSTRACT
Objective:To analyze the epidemic status and spatial and temporal cluster distribution of visceral leishmaniasis (VL) in Gansu Province, and to provide evidence for making precise prevention and control measures and epidemic surveillance.Methods:The data of VL cases in Gansu Province reported in the China Disease Prevention and Control Information System Infectious Disease Reporting Information Management System from 2015 to 2021 were collected, descriptive epidemiology analysis was performed (three distribution of the disease). SaTScan v9.6 and ArcMap 10.7 were used for spatio-temporal cluster analysis.Results:A total of 368 VL cases were reported from 2015 to 2021, 89.13% (328/368) were concentrated in Longnan City and Gannan Tibetan Autonomous Prefecture. The number of VL cases increased year by year from 2015 to 2017, reaching a peak in 2017 (79 cases, accounting for 21.47%), and had decreased year by year since 2018. There were cases every month throughout the year, and the peak was in April in spring (38 cases). The ratio of male to female patients was 1.3 ∶ 1.0 (208/160). Scattered children aged less than 5 years old were more common (41.30%, 152/368). The spatio-temporal cluster analysis showed that both the spatial and temporal aggregation zones of VL in Tanchang County and Chengxian County were of statistical significance ( P < 0.05). Conclusion:The incidence of VL in Gansu Province is showing a low epidemic trend, having spatio-temporal aggregation, and precise monitoring and prevention and control should be strengthened in epidemic areas with different prevalence levels.

@#Abstract: Objective To analyze the influencing factors of mother-to-child transmission of hepatitis B virus after combined immunological blockade, and to evaluate the effect of mother-to-child blockade, and to provide a basis for health policies and health interventions for preventing mother-to-child blockade of hepatitis B virus. Methods A total of 11 363 pairs of HBsAg positive pregnant women and their infants aged 7-12 months in Hainan Province from 2015 to 2020 were included in the study. The general situation, the situation of health care and delivery in this pregnancy and perinatal period, the detection of hepatitis B markers, the situation of antiviral therapy, the general situation of mother and infant during delivery and the implementation of blockade measures for mother-to-child transmission of hepatitis B were collected and analyzed. Results Among the 11 363 pairs of HBsAg positive pregnant women and their infants delivered in hospitals in Hainan province from 2015 to 2020, the positive rate of HBsAg in children at 7-12 months after birth was 1.47 %, and the difference in HBsAg positive rate of infants born in different years was not statistically significant (P>0.05). There were no significant differences in the positive rate of HBsAg among children born to pregnant women with different nationalities, educational levels, occupations, delivery modes, delivery places, obstetric operations and perineal laceration, abnormal perinatal period, children with different genders and premature delivery and perinatal (all P<0.05). There was significant difference in HBsAg positive rate among infants born to pregnant women of different ages, the positive rate of HBsAg of infants born to young pregnant women was higher than that of older pregnant women (P<0.05). The rate of antiviral therapy was low in HBeAg positive pregnant women, and the positive rate of HBsAg in their infants was 2.54%, which was higher than 0.83% in HBeAg negative pregnant women (P<0.05). Conclusions Combined immunological blockade with hepatitis B vaccine and hepatitis B immunoglobulin can effectively prevent the mother-to-child transmission of HBV. HBsAg-positive women can give birth at the right age, and HBeAg-positive pregnant women can be treated with antiviral therapy to block mother-to-child transmission, providing the important basis for the formulation of hepatitis B prevention and control strategies and measures.
ABSTRACT
Chirality is one of the fundamental properties of nature, and most of the important molecules in living organisms contain chiral structures. The efficacy and safety of drugs are often closely related to the chiral structure of compounds, however, there are relatively more studies on synthetic characterization, pharmacology, and toxicology of chiral small molecule chemical drugs, but relatively less studies on chiral compounds contained in natural drugs such as traditional Chinese medicines. Chiral separation, as the basis of chiral research, has a pivotal position in the study of chiral compounds. In this paper, we systematically describe the separation methods of chiral compounds from the classification of chiral splitting methods based on chromatographic and non-chromatographic methods, as well as chromatographic packing materials, chiral additives and chiral derivatization, and review the chiral compounds in natural drugs such as traditional Chinese medicines reported in the past ten years, in order to provide references for the splitting and evaluating the activity of chiral compounds, and the improvement of quality standards of traditional Chinese medicines.
ABSTRACT
NDFIP1 has been previously reported as a tumor suppressor in multiple solid tumors, but the function of NDFIP1 in NSCLC and the underlying mechanism are still unknown. Besides, the WW domain containing proteins can be recognized by NDFIP1, resulted in the loading of the target proteins into exosomes. However, whether WW domain-containing transcription regulator 1 (WWTR1, also known as TAZ) can be packaged into exosomes by NDFIP1 and if so, whether the release of this oncogenic protein via exosomes has an effect on tumor development has not been investigated to any extent. Here, we first found that NDFIP1 was low expressed in NSCLC samples and cell lines, which is associated with shorter OS. Then, we confirmed the interaction between TAZ and NDFIP1, and the existence of TAZ in exosomes, which requires NDFIP1. Critically, knockout of NDFIP1 led to TAZ accumulation with no change in its mRNA level and degradation rate. And the cellular TAZ level could be altered by exosome secretion. Furthermore, NDFIP1 inhibited proliferation in vitro and in vivo, and silencing TAZ eliminated the increase of proliferation caused by NDFIP1 knockout. Moreover, TAZ was negatively correlated with NDFIP1 in subcutaneous xenograft model and clinical samples, and the serum exosomal TAZ level was lower in NSCLC patients. In summary, our data uncover a new tumor suppressor, NDFIP1 in NSCLC, and a new exosome-related regulatory mechanism of TAZ.

Objective:To evaluate the effect of closed-loop therapy system in adult non-mechanical ventilation patients in order to provide evidence-based basis for promoting the safety of oxygen therapy.Methods:Randomized controlled trials of closed-oxygen therapy system on the percentage within SpO 2 target, the incidence of hypoxaemia or hyperoxia, oxygen consumption, the mean oxygen therapy days, as well as the length of hospital stay in adult non-mechanical ventilation patients were searched in PubMed, Web of Science, Embase, Cochrane, CNKI, Wanfang, VIP from inception to June 30, 2022. Data extraction, and literature quality evaluation were performed by two researchers independently, RevMan 5.3 was used for meta-analysis. Results:A total of 5 articles including 502 patients were included. The results showed that the closed oxygen therapy system could significantly improve the percentage of time within SpO 2 target of patients ( SMD=1.56, 95% CI 1.22-1.90, Z=9.04, P<0.001) and reduce the percentage of time with hypoxaemia ( SMD=-0.35, 95% CI-0.50--0.19, Z=4.37, P<0.001) or hyperoxia ( SMD=-0.91, 95% CI-1.07--0.75, Z=11.04, P<0.001) of patients. Moreover, the mean oxygen flow rate of closed oxygen therapy ( SMD=-0.64, 95% CI-1.25--0.03, Z=2.07, P<0.05), the mean oxygen therapy days ( SMD=-0.55, 95%, CI-1.06--0.03, Z=2.08, P<0.05), as well as the length of hospital stay ( SMD=-1.68, 95% CI-2.22--1.14, Z=6.11, P<0.001) were lower than those of patients with manual adjustment systems. Conclusion:The closed oxygen therapy system can promote the safety of oxygen use, but it needs clinical application to further explore.
ABSTRACT
Metastatic vascular calcification and calcinosis universalis, as severe complications of parathyroid hyperfunction and hyperparathyroidism, have attracted more attention in patients with renal secondary hyperparathyroidism and primary hyperparathyroidism. But, they are of little concern in patients with long-term negative calcium balance related parathyroid hyperfunction or hyperparathyroidism caused by calcium and/or vitamin D insufficiency (CVI). CVI is common in the population. Relatively low level of serum calcium and negative calcium balance caused by long-term CVI result in parathyroid hyperfunction or hyperparathyroidism, which may cause secretion of PTH beyond the physiological level, leading to bone absorption and release of a large amount of bone calcium into the blood. It may not only cause bone loss and osteoporosis, but also form metastatic vascular calcification or calcinosis universalis presented by cardiovascular diseases and other multi-organ lesions. Early calcium deposition can gradually fade after reasonable treatment, but middle arterial calcification is not easy to fade once it occurs. Therefore, vascular calcification and calcium deposition should be actively prevented and early screened and diagnosed. The early prevention, diagnosis and treatment of parathyroid hyperfunction or hyperparathyroidism can prevent, delay, or even reverse the occurrence and development of metastatic vascular calcification and calcinosis universalis, which is significant for disease prevention and protecting the patients' health influenced by these diseases.
ABSTRACT
In clinical, manually scoring by technician is the major method for sleep arousal detection. This method is time-consuming and subjective. This study aimed to achieve an end-to-end sleep-arousal events detection by constructing a convolutional neural network based on multi-scale convolutional layers and self-attention mechanism, and using 1 min single-channel electroencephalogram (EEG) signals as its input. Compared with the performance of the baseline model, the results of the proposed method showed that the mean area under the precision-recall curve and area under the receiver operating characteristic were both improved by 7%. Furthermore, we also compared the effects of single modality and multi-modality on the performance of the proposed model. The results revealed the power of single-channel EEG signals in automatic sleep arousal detection. However, the simple combination of multi-modality signals may be counterproductive to the improvement of model performance. Finally, we also explored the scalability of the proposed model and transferred the model into the automated sleep staging task in the same dataset. The average accuracy of 73% also suggested the power of the proposed method in task transferring. This study provides a potential solution for the development of portable sleep monitoring and paves a way for the automatic sleep data analysis using the transfer learning method.

AIM: To investigate the changes in peripapillary choroidal thickness(pCT)within 1a of the first episode of acute primary angle closure glaucoma(APACG).METHODS: A prospective cohort study. A total of 31 patients with APACG who admitted to the ophthalmology department of Shijiazhuang People's Hospital from October 2015 to September 2019 were selected, with 31 eyes in attack group, 31 fellow eyes in preclinical group and 30 cases(30 eyes)in control group. pCT of the three groups was measured respectively at the attack period, 1wk, 1, 3, 6mo and 1a after surgery.RESULTS: The pCT of the attack group was thicker than that in the attack period when at 1wk after surgery, and continued to become thinner within the following 1a(P&#x003C;0.05). The pCT of the attack group was thicker than that of the other two groups during the attack period and at 1wk after surgery, while it became thinner at 1a(P&#x003C;0.05). In the attack group, the average pCT was positively correlated with the duration of intraocular hypertension and negatively correlated with the anterior chamber depth(P&#x003C;0.05).CONCLUSION: For patients with first episode of APACG, pCT was diffusely thickened during attack and at 1wk after surgery. The pCT returned to normal at 1mo, while it became thinner at 1a. Furthermore, the average pCT was positively correlated with the duration of intraocular hypertension, and the choroidal thickness may play an important role in the attack of APACG.
ABSTRACT
The thalamocortical (TC) circuit is closely associated with pain processing. The hyperpolarization-activated cyclic nucleotide-gated (HCN) 2 channel is predominantly expressed in the ventral posterolateral thalamus (VPL) that has been shown to mediate neuropathic pain. However, the role of VPL HCN2 in modulating TC circuit activity is largely unknown. Here, by using optogenetics, neuronal tracing, electrophysiological recordings, and virus knockdown strategies, we showed that the activation of VPL TC neurons potentiates excitatory synaptic transmission to the hindlimb region of the primary somatosensory cortex (S1HL) as well as mechanical hypersensitivity following spared nerve injury (SNI)-induced neuropathic pain in mice. Either pharmacological blockade or virus knockdown of HCN2 (shRNA-Hcn2) in the VPL was sufficient to alleviate SNI-induced hyperalgesia. Moreover, shRNA-Hcn2 decreased the excitability of TC neurons and synaptic transmission of the VPL-S1HL circuit. Together, our studies provide a novel mechanism by which HCN2 enhances the excitability of the TC circuit to facilitate neuropathic pain.

Purpose@#Ankle pump exercises (APE) have been widely used in clinical practice. However, best practices for APE have not been established. Recognize the most effective frequency of APE for improving lower extremity hemodynamics and establish recommendations in clinical practice. @*Methods@#Therefore, a systematic review and network meta-analysis (NMA) was performed according to PRISMA-NMA. Six English databases (Pubmed, Medline, CINAHL, Embase, the Cochrane library and ProQuest) and four Chinese databases (CNKI, Wanfang, VIP and Sinomed) were searched. Randomized controlled trials (RCTs) and quasi-experimental studies investigating the effects of different frequencies of APE on lower limb hemodynamics published before July 2022 were included. The reference list was also searched. Seven studies (one RCTs and six quasi-experimental studies) were included in the systematic review and five studies (one RCTs and four quasi-experimental studies) were included in the NMA. The risk of bias was assessed using the Cochrane and Joanna Briggs Institute tools. The NMA was performed using the R software (version 4.2.1) and OpenBUGS (version 3.2.3). @*Results@#The results of the NMA showed that a frequency of every 3–4 s the most effective in improving lower extremity hemodynamics (P =.85), followed by every 1–2 s (P = .81), every 5–6 s (P=.32) and less than every 10 s (P =.02). Subgroup analysis failed to find a difference between healthy participants and those with unilateral total hip arthroplasty or fracture (MD = −0.23, 95% CI-5.92 to 4.61). @*Conclusions@#Consequencely, for adult patients, with or without lower extremity disease, a frequency of every 3–4 s can be recommended as the optimal frequency of APE in clinical care practice.Registered number on PROSPEROCRD42022349365. https://www.crd.york.ac.uk/PROSPERO/display_record.php?RecordID=349365.
ABSTRACT
Sophorae Flavescentis Radix is the dried root of Sophora flavescens Ait. and Sophorae Tonkinensis Radix et Rhizoma is the dried root and rhizome of Sophora tonkinensis Gagnep. The two drugs are both from the same genus Sophora, having similar and different compositions and efficacies, however, their differences are not fully demonstrated in current standard. In this study, the high-performance thin-layer chromatography with multi-dimensional and multi-level features combined with electric spray mass spectrometry (HPTLC-ESI-MS) was used to discover and identify the characteristic zones in extracts of Sophorae Flavescentis Radix and Sophorae Tonkinensis Radix et Rhizoma, after optimizing the preparation method of the test solution and chromatographic parameters. As a result, 17 main characteristic zones were found on HPTLC chromatograms of Sophorae Flavescentis Radix and Sophorae Tonkinensis Radix et Rhizoma, among them, besides 3 known chemicals, another 12 unknown components were identified by HPTLC-ESI-MS, they are 1 alkaloid and 11 flavonoids. The identification results were verified by the reference standards partially and nuclear magnetic resonance spectra after guided-isolation. Finally, a unified HPTLC specific identification method with different markers was established to identify Sophorae Flavescentis Radix and Sophorae Tonkinensis Radix et Rhizoma simultaneously. Thanks to abundant chemical information provided when using diverse polarity mobile phases and derivatization reagents, the HPTLC technology offers a convenient strategy for discovery, quality evaluation, and identification of target chemicals when connecting with mass spectrometry.

Methods Four cities and counties were randomly selected as the intervention group, and four cities and counties matched with the intervention group in terms of population, economy, social culture, maternal and child health work foundation of township health centers, physical nutrition and health status were selected as the control group.With the combination of monitoring and prospective cohort study, infants in the intervention group and the control group were studied from June 1, 2020, and they were intervened for 12 months with supplementary food nutrition package. Before and after intervention, the nutrition and health status of infants aged 6-24 months in the intervention group and the control group were investigated to evaluate the nutritional and health effects of supplementary food nutrition package for infants aged 6-24 months in rural Hainan Province. Results A total of 999 infants were investigated, including 427 in the intervention group and 572 in the control group. After 12 months of nutritional intervention, there was no significant difference in weight-for-age Z-score (WAZ) and height-for-age Z-score (HAZ) and weight-for-height Z-score (WHZ) between the intervention group and the control group (P>0.05). The rate of emaciation of the intervention group was 1.64%, which was significantly lower than 3.67% of the control group (P<0.05). There were no significant differences in the rate of growth retardation (2.81% and 3.32%, respectively) and underweight (0.47% and 1.92%, respectively) between the intervention group and the control group (P>0.05). The rate of respiratory infection and diarrhea in the intervention group were 9.13% and 1.17%, which were significantly lower than corresponding 23.25% and 3.15% in the control group (P<0.05). The hemoglobin of the intervention group and the control group were 117.24 g/L and 114.51 g/L respectively, and the rates of anemia were 11.11% and 22.84% respectively, the differences were statistically significant (P<0.05). Conclusions The intervention of nutrition package in rural areas of Hainan Province has achieved the expected results, and supplementary food nutrition package has reduced the incidence of malnutrition and respiratory infection and diarrhea in recent two weeks in infants and anemia to a certain extent. We should attach great importance to the supplementary nutrition package for right-age children and promote the growth and health of children in rural areas through supplementary nutrition package, and continuously improve the nutrition and health level of children in Hainan Province.
ABSTRACT
Objective:To summarize the characteristics of neuralgia in Fabry disease and explore the effects of genders and alpha-galactosidase A (GLA) gene mutation types on neuralgia.Methods:Questionnaires and Brief Pain Inventory evaluations were conducted on the recruited patients diagnosed as Fabry disease in Department of Neurology, Peking University First Hospital from January 2001 to April 2020. The characteristics of the neuralgia were summarized, and the portrait of neuralgia between male and female patients, and the patient groups carrying truncated mutations and non-truncated mutations of GLA gene was compared.Results:A total of 93 patients with Fabry disease were enrolled. The incidence of neuralgia was 91.4% (85/93),and the average onset age of pain was 9 years. The average remission age was 20 years with the remission incidence of 22.8% (18/79). Pain attack on extremities [96.5%(82/85)] was the most common form. The neuralgia relieving rate of male patients [17.5%(11/63)] was lower than that of females (7/16, χ2=5.01, P=0.025).Brief Pain Inventory scores showed that the degree of most severe pain attack within 24 hours of male patients (4.16±3.20) was higher than that of females (2.07±2.02, t=3.03, P=0.004),and the impact of pain on daily life [male 4 (7) vs female 0 (4), Z=-2.33, P=0.020], walking ability [male 5 (8) vs female 0 (2), Z=-2.87, P=0.004], daily work [male 5 (8) vs female 0 (2), Z=-3.10, P=0.002], relationship [male 2 (6) vs female 0 (3), Z=-2.67, P=0.008] and interests [male 4 (8) vs female 0 (3), Z=-2.81, P=0.005] of male patients was also higher than female patients. The truncated mutation group [1 (2)] only showed higher score on the current pain level than the non-truncated mutation group [0(0), Z=-2.89, P=0.003]. Conclusions:The neuralgia in Chinese patients with Fabry disease showed high incidence and early onset. Male patients presented more severe pain than female which led to a greater impact on life, while the type of GLA gene mutation had less impact on neuralgia.
ABSTRACT
Objective:To investigate the effect of enteral nutrition on hematological complications in children with malignant solid tumors during chemotherapy.Methods:A total of 103 children with malignant solid tumor admitted to our hospital from March 2020 to December 2020 were enrolled in the study. The children were randomly divided into enteral nutrition group ( n=51) and control group ( n=52). Children in enteral nutrition group were given enteral nutrition support on the basis of routine diet, while children in control group were only given routine diet. The levels of leukocytes, neutrophils, hemoglobin and platelets in peripheral blood of children during chemotherapy were analyzed. The incidence of infection and the transfusion of red blood cells and platelets after chemotherapy were documented and compared between two groups. Results:The levels of white blood cells, neutrophils, hemoglobin and platelets before chemotherapy were significantly higher than those after chemotherapy both in enteral nutrition group ( Z=-5.91, -5.59, -5.54, -5.66, all P<0.05) and in control group ( Z=-6.14, -5.84, -5.75, -4.75, all P<0.05). The overall hemoglobin levels in enteral nutrition group before and after chemotherapy was significantly higher than those in control group ( t=5.68, 5.62, P<0.05), and there were no significant differences in the levels of white blood cells, neutrophils and platelets between the two groups before chemotherapy ( Z=-0.71, -0.12, -1.29, all P>0.05) and after chemotherapy ( Z=-0.39, -0.86, -0.94, all P>0.05). Compared with the control group, the degree of anemia during chemotherapy was significantly improved in enteral nutrition group (χ2=10.45,6.12, all P<0.05), but there was no significant difference in the reduction degree of white blood cells, neutrophils and platelets between the two groups (before chemotherapy: χ2=1.17, 0.10, 0.49; after chemotherapy: χ2=0.18, 1.10, 0.97, all P>0.05). The number of children receiving red blood cell transfusion in enteral nutrition group was significantly lower than that in control group (χ2=14.06, P<0.05), and there was no significant difference in the number of children with infection and platelet transfusion between the two groups (χ2=1.20, 0.29, all P>0.05).There was no significant difference in the duration of neutrophil deficiency between enteral nutrition group and control group ( t=-1.75, P>0.05). Conclusion:Enteral nutrition support can significantly improve the hemoglobin level in children during chemotherapy, effectively alleviate the severity of anemia, and reduce the incidence of red blood cell transfusion after chemotherapy, which has high clinical application value.

There were 109 males and 64 females, with an average age of (53.29±13.58) years, median tumor diameter of 70 (23-150) mm, 68 patients with local symptoms, 24 patients with systemic symptoms, and 56 patients with ECOG score ≥1. There were 96 patients with tumor pseudocapsule, 23 patients with renal vein or inferior vena cava tumor thrombus, 114 patients in stage T 1-2, 59 patients in stage T 3-4, 22 patients with distant metastasis and 88 patients with lymph node metastasis by preoperative imaging examination. Univariate analysis was performed by Mann-Whitney U test or Chi-square test, and multivariate logistic regression analysis was used to determine preoperative predictors of pathologic lymph node positivity. The significant variables were then included in a novel Nomogram to predict the probability of lymph node invasion.C-index and Bootstrap self-sampling methods were used to evaluate the discrimination and consistency of the model. Results:Of the 173 patients, 49(28.32%)and 124(71.68%)had pN 1 and pN 0 disease, respectively. Among 88 patients with suspected lymph node involvement (cN 1) assessed by preoperative imaging, only 47.73%(42/88) were confirmed to be pathologically positive. However, 8.24% (7/85) of the 85 patients with negative lymph nodes (cN 0) assessed by preoperative imaging were pathologically positive. Age, ECOG score, symptoms at presentation, tumor pseudocapsule, metastasis at diagnosis, clinical tumor stage, clinical nodal status, clinical nodal size, D-dimer, lactate dehydrogenase, microscopic hematuria were significant in the univariate analysis ( P<0.05). On multivariable analyses, the most informative independent predictors were age, clinical tumor stage, clinical nodal status, clinical nodal size and microscopic hematuria ( P<0.05). A Nomogram with good performance was developed to predict the probability of lymph node metastasis. The C-index of the model was 0.954, the calibration curve of forecasting curve with the ideal curve fit was good, indicating that the model has a good consistency. Conclusions:Younger age, microscopic hematuria, suspected lymph node involvement in imaging, larger lymph node diameter and higher T stage were independent risk factors for renal cell carcinoma with lymph node metastasis. The Nomogram based on the above factors has good identification and calibration ability, which can help predict the probability of lymph node metastasis of renal cell carcinoma before surgery.
ABSTRACT
Objective:To systematically evaluate the relationship between growth and thyroid volume (Tvol).Methods:Chinese and English papers were searched in CNKI, Wanfang Data, VIP Database, PubMed, EMbase, Springerlink, Medline database, articles on the correlation between Tvol and growth in children published from the establishment of these databases to October 2021 were collected. Meta-analysis was conducted with R language 4.0. I2 and Q test were used for heterogeneity test. According to the heterogeneity test results, the fixed effect model or random effect model was selected, and sensitivity analysis was conducted. Egger's method was used to test publication bias. Results:A total of 17 papers were incorporated in this study, including 11 Chinese papers and 6 English papers. The correlation between body surface area (BSA) and Tvol was the strongest[estimated effect value ( COR) = 0.44, 95% confidence interval ( CI): 0.39 - 0.50], followed by weight ( COR = 0.39), height ( COR = 0.37) and age ( COR = 0.29). Sensitivity analysis showed that the estimated effects COR were all within 95% CI of the total effects after deleting any paper, which indicated that the results of Meta-analysis were reliable. Egger's method result showed P > 0.05, indicating that there was no obvious publication bias in this study. Conclusion:Age, height, weight and BSA all have effects on Tvol, among which BSA has the greatest effect.
