Objective: To investigate the relationship between hemoglobin and serum uric acid in adults with various glucose metabolism status. Methods: The demographic data and biochemical indicators of the adult population who had received physical examination in the Second Medical Center of the PLA General Hospital from January 2018 to December 2021 were collected. The subjects were divided into two groups according to the level of serum uric acid: the normal uric acid group and the hyperuricemia group. The relationship between hemoglobin (stratified into four levels of Q1 to Q4 by the quartile) and serum uric acid was quantified by using Pearson correlation and logistic regression analysis. The effects of age and glucose metabolism status on the relationship between hemoglobin and serum uric acid were analyzed. Results: A total of 33 183 adults were enrolled with age (50.6±10.0) years. The level of hemoglobin in the normal uric acid group (142.61±14.24) g/L was significantly lower than that in the hyperuricemia group [(151.79±11.24) g/L, P<0.001]. Univariate Pearson correlation analysis showed that hemoglobin was positively associated with serum uric acid (r=0.444, P<0.001). After adjusting for related confounding factors, multivariate logistic regression analysis showed that hemoglobin was associated with serum uric acid, and the OR values (95%CI) of hemoglobin Q2 to Q4 group were 1.29 (1.13-1.48), 1.42 (1.24-1.62) and 1.51 (1.32-1.72), respectively (Ptrend<0.001) when compared with hemoglobin Q1 group. Subgroup analysis and hierarchical interaction analysis suggested that with the increase of hemoglobin, the serum uric acid in the age<60 years subgroup, normal glucose subgroup and prediabetes subgroup increased gradually (Ptrend<0.05 and Pinteraction<0.001). Conclusion: The association between hemoglobin and serum uric acid in adults is affected by age and glucose metabolism status.

Objective:To establish and validate a nomogram model for early prediction of the risk of acute pancreatitis (AP) progressing to severe acute pancreatitis (SAP).Methods:CT signs and clinical laboratory parameters of 361 AP patients admitted to our Hospital from January 2016 to July 2022 were retrospectively collected. There were 221 males (61.2%) and 140 females (38.8%). According to the Atlantic score, all patients were divided into the SAP group (64 cases) and the non-SAP (NSAP) group (297 cases). Univariate analysis was used to screen out variables with statistically significant differences. Multivariate Logistic regression analysis was used to screen out the independent risk factors of SAP, and finally a nomogram prediction model was established. Receiver operating characteristic (ROC) curve, calibration curve and decision curve (DCA) were used to evaluate the predictive efficacy, accuracy and clinical practicability of the model, and Bootstrap method was used to verify the model internally.Results:Univariate analysis and multivariate Logistic regression analysis showed that pleural effusion ( OR=7.353, 95% CI: 3.344-16.170), posterior pararenal space (PPS) involvement ( OR=3.149, 95% CI: 1.314-7.527), serum creatinine concentration (Cr) ( OR=1.027, 95% CI: 1.017-1.038) and serum calcium concentration (Ca 2+) ( OR=0.038, 95% CI: 0.009-0.166) were independent risk factors for SAP ( P<0.05). A Nomogram model was established based on these four factors. The area under the ROC curve (AUC) of this model was 0.905 (95% CI: 0.869-0.933), indicating high predictive efficiency. Internal verification showed that the model had good accuracy in predicting SAP, and C-index was 0.90. DCA analysis showed that the model had high clinical practicability. Conclusions:The Nomogram model combining pleural effusion, PPS involvement, Cr and Ca 2+ had a good effect on early prediction of SAP, which could provide a new reference tool for clinical diagnosis and treatment.

OBJECTIVE@#To study the clinical, imaging, and pathological features of pulmonary lymphoma.@*METHODS@#Patients with pulmonary lymphoma diagnosed by lung biopsy in Zhongda Hospital Affiliated to Southeast University from November 2013 to December 2020 were collected and divided into secondary pulmonary lymphoma (SPL) group and primary pulmonary lymphoma (PPL) group according to the primary site of lymphoma. The clinical characteristics, stages, imaging features, diagnostic methods and pathological types of the two groups were analyzed.@*RESULTS@#A total of 22 patients were included, 10 cases were PPL and 12 cases were SPL. The main symptoms of the two groups were cough, dyspnea and chest pain. The proportion of stage III/IV patients and international prognostic index (IPI) in SPL group were significantly higher than those in PPL group (P<0.05). Chest high-resolution computed tomography (HRCT) mainly showed masses, nodules and consolidation in both groups. The proportions of single mass and air bronchial sign in PPL group were significantly higher than those in SPL group, while the proportions of multiple nodules, mediastinal/hilar lymphadenopathy and pleural effusion were significantly lower (P<0.05). The max standardized uptake value (SUVmax), peak standardized uptake value (SUVpeak), total lesion glycolysis (TLG) and metabolic tumor volume (MTV) of 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography/computed tomography (PET/CT) in PPL group were lower than those in SPL group, but the differences were not statistically significant (P>0.05). In PPL group, 8 cases were diagnosed by transbronchial lung biopsy (TBLB) and 2 cases by percutaneous lung puncture. In SPL group, 4 cases were diagnosed by TBLB, 7 cases by percutaneous lung puncture, and 1 case by surgery. 95.5% patients were diagnosed by non-surgical methods. The main pathological type of PPL was mucosa-associated lymphoid tissue (MALT) lymphoma, while that of SPL was diffuse large B-cell lymphoma (P<0.05).@*CONCLUSION@#The clinical symptoms of pulmonary lymphoma are nonspecific, but the chest HRCT has characteristic manifestations, which can also help to distinguish between SPL and PPL. 18F-FDG PET/CT is also a potential method to distinguish between SPL and PPL. TBLB and percutaneous lung puncture biopsy are reliable methods for the diagnosis of lung lymphoma. The main pathological type of PPL is MALT lymphoma, while that of SPL is diffuse large B-cell lymphoma.

Based on the concept of quality by design(QbD), the Box-Behnken design-response surface methodology combined with standard relation(SR) and analytic hierarchy process(AHP)-entropy weight method(EWM) was applied to optimize the extraction process of the classic prescription Yihuang Decoction. The content of geniposidic acid, phellodendrine hydrochloride, and berberine hydrochloride in Yihuang Decoction, the extract yield, and fingerprint similarity were used as the critical quality attributes(CQAs) of the extraction process. The extraction time, water addition, and extraction times were used as the critical process parameters(CPPs). After determining the levels of each factor and level through single-factor experiments, response surface experiments were designed according to the Box-Behnken principle, and the experimental results were analyzed. The SR between each sample and the reference sample under various evaluation indicators of different extraction parameters was calculated. The weights of the five evaluation indicators were determined using AHP-EWM, followed by comprehensive evaluation. A function model between CPPs and CQAs characterized by comprehensive scores was established to predict the optimal extraction process parameters. In the final comprehensive weight coefficients, the yield rate accounted for 43.1%, and the content of berberine hydrochloride, phellodendrine hydrochloride, and geniposidic acid accounted for 35.1%, 6.3%, and 15.5%, respectively. After comprehensive score analysis with SR, the established second-order polynomial model was statistically significant(P<0.01, and the lack of fit was not significant). The predicted optimal extraction conditions for Yihuang Decoction were determined as follows: 8-fold volume of water, extraction time of 1.5 h, and extraction once. The mean comprehensive score of the validation experiment was 85.77, with an RSD of 0.99%, and it met the quality control stan-dards for the reference sample of Yihuang Decoction. The results indicate that the optimized extraction process for Yihuang Decoction is stable and reliable, and the water extract is close in quality attributes to the reference sample. This can serve as a foundation for the research and development of granules in the future. Box-Behnken design-response surface methodology combined with SR and AHP-EWM can provide references for the modern extraction process research of other classic prescriptions.

This study combined the herbal pair Platycodonis Radix-Curcumae Rhizoma(PR-CR) possessing an inhibitory effect on tumor cell proliferation and metastasis with the active component of traditional Chinese medicine(TCM) silibinin-loaded nanoparticles(NPs) with a regulatory effect on tumor microenvironment based on the joint effect on tumor cells and tumor microenvironment to inhi-bit cell metastasis. The effects of PR-CR on the cellular uptake of NPs and in vitro inhibition against breast cancer proliferation and metastasis were investigated to provide an experimental basis for improving nanoparticle absorption and enhancing therapeutic effects. Silibinin-loaded lipid-polymer nanoparticles(LPNs) were prepared by the nanoprecipitation method and characterized by transmission electron microscopy. The NPs were spherical or quasi-spherical in shape with obvious core-shell structure. The mean particle size was 107.4 nm, Zeta potential was-27.53 mV. The cellular uptake assay was performed by in vitro Caco-2/E12 coculture cell model and confocal laser scanning microscopy(CLSM), and the results indicated that PR-CR could promote the uptake of NPs. Further, in situ intestinal absorption assay by the CLSM vertical scanning approach showed that PR-CR could promote the absorption of NPs in the enterocytes of mice. The inhibitory effect of NPs on the proliferation and migration of 4T1 cells was analyzed using 4T1 breast cancer cells and co-cultured 4T1/WML2 cells, respectively. The results of the CCK8 assay showed that PR-CR-containing NPs could enhance the inhibition against the proliferation of 4T1 breast cancer cells. The wound healing assay indicated that PR-CR-containing NPs enhanced the inhibition against the migration of 4T1 breast cancer cells. This study enriches the research on oral absorption of TCM NPs and also provides a new idea for utilizing the advantages of TCM to inhibit breast cancer metastasis.

The plant growth, development, and secondary metabolism are regulated by R2 R3-MYB transcription factors. This study identified the R2 R3-MYB genes in the genome of Andrographis paniculata and analyzed the chromosomal localization, gene structure, and conserved domains, phylogenetic relationship, and promoter cis-acting elements of these R2 R3-MYB genes. Moreover, the gene expression profiles of R2 R3-MYB genes under abiotic stress and hormone treatments were generated by RNA-seq and validated by qRT-PCR. The results showed that A. paniculata contained 73 R2 R3-MYB genes on 21 chromosomes. These members belonged to 34 subfamilies, 19 of which could be classified into the known subfamilies in Arabidopsis thaliana. The 73 R2 R3-MYB members included 36 acidic proteins and 37 basic proteins, with the lengths of 148-887 aa. The domains, motifs, and gene structures of R2 R3-MYBs in A. paniculata were conserved. The promoter regions of these genes contains a variety of cis-acting elements related to the responses to environmental factors and plant hormones including light, ABA, MeJA, and drought. Based on the similarity of functions of R2 R3-MYBs in the same subfamily and the transcription profiles, ApMYB13/21/35/67/73(S22) may regulate drought stress through ABA pathway; ApMYB20(S11) and ApMYB55(S2) may play a role in the response of A. paniculata to high temperature and UV-C stress; ApMYB5(S7) and ApMYB33(S20) may affect the accumulation of andrographolide by regulating the expression of key enzymes in the MEP pathway. This study provides theoretical reference for further research on the functions of R2 R3-MYB genes in A. paniculata and breeding of A. paniculata varieties with high andrographolide content.

摘要
ObjectiveTo screen the appropriate reference genes for real-time fluorescence-based quantitative polymerase chain reaction（Real-time PCR）analysis of the Andrographis paniculata under methyl jasmonate（MeJA）and various abiotic stresses. MethodThe actin 1（ACT1），actin 2（ACT2），elongation factor（EF-1α），glyceraldehyde-3-phosphate dehydrogenase（GAPDH），tubulin（TUB），polyubiquitin（UBQ）， and 18S rRNA（18S）gene were selected as candidate reference genes based on the RNA-seq data of high temperature，drought， UV， and MeJA. The expression of seven candidate reference genes in the A. paniculata leaves was assessed by Real-time PCR，and the stability was analyzed by geNorm，NormFinder，BestKeeper， and Refinder. ResultThe results of stability evaluated by geNorm，NormFinder， and BestKeeper were not the same due to different indicators. As analyzed by Refinder， for the stability of the expression， the genes were ranked as UBQ>18S>EF-1α>ACT2>ACT1>GAPDH>TUB under high temperature stress， ACT1>UBQ>EF-1α>18S>ACT2>GAPDH>TUB under drought stress， EF-1α>TUB>ACT2>UBQ>18S>GAPDH>ACT1 under UV stress， and ACT1>EF-1α>UBQ>ACT2>18S>TUB>GAPDH under MeJA stress. Among them，18S gene was not suitable as an internal reference gene duo to its high expressive abundance. This study also verified the relative expression level of andrographolide synthesis-related gene hydroxy-methylglutaryl-CoA synthase （HMGS） in the four stresses on the basis of transcriptome data，and found that the Real-time PCR results of appropriate internal reference genes were accurate and reliable. ConclusionUBQ-ACT1-UBQ，EF-1α-TUB，and ACT1-EF-1α were the suitable combinations under stresses of high temperature，drought，UV， and MeJA. This study is expected to provide references for the research on function regulation and expression of genes in A. paniculata under high temperature，drought，UV， and MeJA stresses.

Objective:To investigate the clinical experiences and outcomes of protection of branches during clipping of low grade internal carotid communicating segment (C7) aneurysms via frontolateral keyhole approach. Methods:Fifty-two patients with internal carotid C7 aneurysms and Hunt-Hess grading I-III, admitted to our hospital from January 2017 to December 2020, were chosen; 45 patients were with posterior communicating artery (PCoA) aneurysms, 6 patients were with anterior choroidal artery (ACHA) aneurysms, and one patient was with PCoA aneurysm combined with ACHA aneurysm. The relation between origin of the branch arteries and tumor neck was determined during surgery. The relation between shape of the branch arteries and tumor body was investigated in the Spaces II, III and V of the internal carotid artery (indocyanine green fluorescence angiography was used when necessary); the aneurysms were clipped by appropriate aneurysm clip or clips combination; after clipping, microspic or endoscopic exploration and indocyanine green fluorescence angiography were performed, and re-clipping was performed in the misclipped or stenosed branch arteries.Results:During the surgery, the branch arteries of 6 patients (4 from posterior communicating artery, 1 from anterior choroidal artery, and 1 from perforator artery at the bifurcation of internal carotid artery) were misclipped, and therefore, the aneurysm clips were adjusted or replaced and then re-clipped. Aneurysms were successfully clipped in all 52 patients. Brain CT examination within 24 h of surgery showed that focal cerebral infarction in the branch artery feeding area was noted in 5 patients, of which 3 patients were accompanied by contralateral limb muscle strength decline (grading 4, grading 3 and grading 1, respectively) and medication and neurological rehabilitation were given. The other 47 patients had good general condition without special condition. During the follow-up of 9-12 months, the muscle strength of 3 patients with decreased contralateral limb strength recovered to grading 5, 4 and 2, respectively. There were no residual or recurrent aneurysms in all patients. At the last follow-up, 47 patients had Glasgow Outcome scale (GOS) scores of 5, 3 patients had GOS scores of 4, 1 patient had GOS scores of 3, and 1 patient had GOS scores of 2.Conclusion:In the treatment of low-grade internal carotid artery C7 segment aneurysms via frontolateral keyhole approach, multiple protective strategies can be adopted to actively prevent branch artery injury, which can effectively reduce the incidence of postoperative cerebral infarction and improve the prognosis.

Among them, 40 patients were treated with six-step method VIT, and 42 patients were treated with photoselective vaporization of prostate (PVP). The two groups of patients were compared in age [(71.1±8.7)years vs.(72.1±7.0)years], prostate volume [75 (68.25, 89.00) ml vs. 73 (63.25, 85.00) ml], and peak urinary flow rate (Q max) [6.20 (5.20, 8.20) ) ml/s vs. 5.9 (4.75, 7.50) ml/s], post-void residual volume (PVR) [74.00 (42.50, 103.75) ml vs. 67.00 (58.00, 84.50) ml], international prostate symptom score (IPSS) [(21.2±5.2) vs. ( 21.0±3.9)], quality of life score (QOL) [5 (4, 6) vs. 5 (4, 6) ], prostate specific antigen (PSA) [6.20 (4.12, 8.43) ng/ml vs. 5.40 (3.88, 7.13) ng/ml ]. In general, there was no statistical difference ( P>0.05). The VIT group adopts the six-step method of marking, removing film, grooving, excision, trimming and crushing. In the PVP group, the prostate tissue was uniformly vaporized layer by layer from the inside to the outside. Perioperative indexes and complications were compared between the two groups. The Q max, IPSS, QOL, PVR and PSA between the two groups before and 3 months after surgery were compared. Results:All patients in the VIT group and PVP group successfully completed the surgery, and there was no case of transfer to TURP or open surgery. The average operation time was [60.00(50.00, 73.75)min vs. 70.00(50.00, 73.75)min] ( P<0.05). There was no significant difference in the amount of postoperative hemoglobin decline[15.00(10.00, 17.75)g/L vs. 16.00(14.00, 19.25)g/L], average bladder irrigation time[1(1, 1)d vs. 1(1, 1)d], indwelling catheterization time[3(3, 3)]d vs. 3(3, 3)d] and hospitalization time in patients after operation[4(3, 4)d vs. 4(4, 4)d] ( P>0.05). All patients had no blood transfusion, second bleeding, readmission, TURS, urethral stricture and urinary incontinence.There were 2 cases (5.0%) of postoperative urinary tract infection in the VIT group and 9 cases (21.4%) of postoperative urinary tract infection in the PVP group ( P<0.05), and they were cured after anti-inflammatory treatment. Three months after operation, Q max, IPSS, QOL, PVR and PSA in the two groups were significantly improved compared with preoperatively. Among them, the differences of IPSS [(5.7±2.5) points vs. (7.5±2.8) points] and PSA [2.65(2.10, 3.90)ng/ml vs. 4.00(2.45, 4.45)ng/ml] in the VIT group and PVP group after operation were statistically significant ( P<0.05). Conclusions:Applying the six-step method high power side-emitting greenlight laser transurethral anatomical VIT to treat BPH, there is less intraoperative and postoperative bleeding, short operation time, significant decrease in PSA, and fewer complications. It is a safe and effective minimally invasive technology for the treatment of BPH.

Objective: To observe the clinical efficacy of thunder-fire moxibustion for hypomenorrhea after induced abortion. Methods: A total of 74 patients with hypomenorrhea after induced abortion were randomized into two groups, with 37 cases in each group. The control group was treated with conventional hormone sequential therapy, and the observation group was treated with thunder-fire moxibustion. The course of treatment was 3 menstrual cycles. The traditional Chinese medicine (TCM) symptom scores, menstrual volume, endometrial thickness and the sex hormone levels were observed before and after treatment. The clinical efficacy was compared after treatment. Results: The total effective rate in the observation group and the control group was 91.4％ and 73.5％, respectively, and the difference between the two groups was statistically significant (P<0.05). After treatment, the TCM symptom scores in both groups decreased significantly (all P<0.05), and the scores in the observation group were lower than those in the control group (P<0.05). The menstrual volume, endometrial thickness and each sex hormone level of the patients in both groups were significantly improved after treatment (all P<0.05), and the improvements in the observation group were more significant than those in the control group (all P<0.05). Conclusion: Thunder-fire moxibustion can significantly improve the clinical symptoms of patients with hypomenorrhea after induced abortion; it can increase menstrual volume and endometrial thickness, and regulate the sex hormone levels, producing a better curative effect than the conventional hormone sequential therapy.
摘要
Hypoxia is a common phenomenon of solid tumor, which is closely related to the malignant proliferation, tumor progression, radiotherapy and chemotherapy resistance, treatment failure, and poor prognosis. At present, many researches focus on the application of medical imaging and nuclear medicine methods in detecting the hypoxic areas of tumors. This article focuses on the detection of hypoxia microenvironment and the application of PET tracers in tumor hypoxia imaging.
摘要
Objective@#The current study aims to explore precipitating and social risk factors for internet addiction (IA) in university undergraduate students, and to provide evidence for interventions and the early prevention of IA in different genders. @*Methods@#Four thousand eight hundred and fifty-eight college sophomores completed an online survey on their internet use-related behaviours and social risk factors. @*Results@#We found that more male (8.3%) than female students (5.4%) had moderate and severe IA. The main online activity in the moderate and severe IA groups was online gaming in males and online streaming in females. Roommates engaging in similar internetbased entertainment was a risk factor of IA only for males, while not being in a romantic relationship was a risk factor of IA for females only. Infatuation with the internet before college and adjustment problems for college life were shared risk factors for both genders in the mild and moderate IA groups. @*Conclusion@#IA was a common phenomenon in college students with shared and unique precipitating and social risk factors in males and females. The gender-sensitive risk factors for IA warranted earlier and individualized intervention and prevention strategies for IA in this population.
