ABSTRACT

In recent years, the quantity of lung transplantation has been gradually increased in China along with the accumulation of surgical techniques and postoperative management experience of lung transplantation. Multiple lung allograft complications may occur after lung transplantation, mainly including primary graft dysfunction (PGD) caused by ischemia-reperfusion injury (IRI) of the lung allograft, acute and chronic rejection, opportunistic infection or lymphoproliferative disorder of lymphoid tissues induced by the decrease of host immunity due to postoperative use of immunosuppressants, etc. The diagnosis of complications after lung transplantation mainly relies on biopsy of the lung allograft. In this article, the brief history of lung allograft pathology, main approaches and pathological processing techniques of lung allograft biopsy, major complications after lung transplantation and pathological diagnostic criteria were elucidated, aiming to provide reference for targeted management of these complications in clinical practice.

ABSTRACT

Pancreas transplantation and pancreas-kidney transplantation are the optimal treatment for renal failure caused by type 1 diabetes mellitus, partial type 2 diabetes mellitus and their complications. Pancreas transplantation mainly includes simultaneous pancreas-kidney transplantation (SPK), pancreas transplantation after kidney transplantation (PAK) and pancreas transplantation alone (PTA). Among all types of pancreas transplantation, biopsy of pancreas allograft remains the best method for definitively diagnosing rejection and differentiate it from other complications. In this article, biopsy methods of pancreas allograft and related research progress, diagnostic criteria and research progress on rejection of pancreas allograft biopsy, and main complications and pathological manifestations of pancreas allograft were illustrated, aiming to provide reference for guiding the clinical diagnosis of the above mentioned complications and ensuring the long-term survival of pancreas allografts and recipients.

ABSTRACT

Objective@#To investigate the prevalence of anxiety and depression among inpatients with AIDS and its influencing factors, so as to provide the evidence for improving the psychological health among inpatients with AIDS.@*Methods@#The inpatients with AIDS that were hospitalized in an infectious disease hospital in Chengdu City were recruited using the convenient sampling method. The demographic features, depression and anxiety were collected using a self-designed questionnaire, Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale ( SDS ), respectively, and factors affecting the development of depression and anxiety were identified using a multivariable linear regression model among inpatients with AIDS.@*Results@#The 228 AIDS inpatients included 186 men (81.58%) and 42 women ( 18.42% ), and had a mean age of ( 48.04±16.03 ) years. There were 113 inpatients ( 49.56% ) with a CD4+T cell count of ≤200 cells/μL, and the mean SAS and SDS standardized scores were 35.87±8.01 and 42.07±11.08 among AIDS inpatients, which were both significantly greater than in normal populations ( P<0.05 ). The prevalence rates of anxiety, depression, and comorbid anxiety and depression were 5.26%, 16.23% and 4.82% among the participants, respectively. Multivariable linear regression analysis identified unemployment as a risk factor of anxiety ( β'=0.168, P<0.05 ), and CD4+T cell count as a risk factor of anxiety ( β'=-0.151, P<0.05 ) and depression ( β'=-0.238, P<0.05 ) among inpatients with AIDS.@*Conclusions@#Anxiety and depression are prevalent among inpatients with AIDS. Unemployment and a low CD4+T cell count may cause a rise in the risk of developing anxiety and depression among inpatients with AIDS.

ABSTRACT

Objective:To investigate the curative effect of decompression with reserved superficial temporal artery for treatment of severe traumatic brain injury (sTBI).Methods:A retrospective case-control study was conducted to analyze the clinical data of 265 patients with sTBI who underwent decompressive craniectomy in Shaanxi Provincial People's Hospital from July 2016 to December 2019. Among them, 152 were males and 113 were females, with the age of 33-72 years [(50.1±12.8)years]. On admission, the Glasgow Coma Score (GCS) was 3-8 points [(5.7±1.4)points]. A total of 135 patients were treated with reserved superficial temporal artery decompression after admission (observation group) and 130 patients were treated with conventional decompression without deliberately preserving the superficial temporal artery (control group). The amount of intraoperative scalp bleeding, scalp healing time, cerebrospinal fluid incision leakage, healing degree and postoperative craniocerebral CT angiography (CTA) were compared between the two groups.Results:All patients were followed up for 7-15 days [(12.4±2.5)days]. The amount of intraoperative scalp bleeding was (15.4±4.5)ml in observation group and (65.2±4.7)ml in control group ( P<0.01). The healing time was (7.1±1.1)days in observation group and (9.5±2.3)days in control group ( P<0.01). There were 5 patients (3.7%) with cerebrospinal fluid incision leakage in observation group compared to 21 patients (16.2%) in control group ( P<0.01). There were 114 patients with Grade A healing in observation group compared to 91 patients in control group ( P<0.05). Based on the postoperative craniocerebral CTA, the superficial temporal artery was intact and the blood supply was normal in observation group, while the main trunk of the superficial temporal artery was disconnected from the zygomatic arch segment and the blood supply was incomplete in control group. Conclusions:For patients with sTBI, decompressive craniectomy with reserved superficial temporal artery can promote the healing of the scalp. Moreover, keeping the superficial temporal artery can significantly reduce the amount of bleeding during operation, reduce postoperative scalp healing time and incidence of cerebrospinal fluid incision leakage and assist cerebral blood perfusion.

ABSTRACT

Objective:To explore the value of matrix metalloproteinase (MMP) in differential diagnosis of brucellosis spondylitis (BS) and tuberculous spondylitis (TS).Methods:Retrospective analysis was used to collect the data of patients with BS and TS diagnosed in the First Affiliated Hospital of Xinjiang Medical University from January 2016 to December 2018. Magnetic resonance imaging (MRI), laboratory data, and the expression levels of MMP-2 and MMP-9 were analyzed.Results:There existed significant differences in imaging findings like the infection levels, the number of infected vertebrae and the paravertebral soft tissue lesions between BS and TS patients ( n=26, 27, P < 0.05). Basophils in BS patients were significantly higher than those in TS patients [(0.022±0.019) × 10 9 number/L vs (0.017±0.007) × 10 9 number/L, t=2.19, P < 0.05]; but the C-reactive protein of BS patients was significantly lower than that of TS patients [(16.12±14.16) mg/L vs (33.78±24.05) mg/L, t=2.45, P < 0.05]. The expression of MMP-9 in BS patients was significantly lower than that in TS patients [76.92% (20/26) vs 96.30% (26/27), χ 2=4.34, P < 0.05], but there was no significant difference in the expression of MMP-2 ( P > 0.05). Conclusion:MMP-9 may be a new biomarker in differential diagnosis of BS and TS, which can be helpful for the differential diagnosis of BS and TS by combining MRI findings with laboratory findings.

ABSTRACT

Objective:To observe the effects of modified Liuwei Dihuangtang on serum fibroblast growth factor 23 (FGF23), full-length intact parathyroid hormone (iPTH), and 1,25-dihydroxyvitamin D<sub>3 </sub>[1,25(OH)<sub>2</sub>D<sub>3</sub>] levels and Klotho and FGF23 protein expression in renal and bone tissues of rats exposed to high phosphorus combined with adenine, so as to explore the mechanism of modified Liuwei Dihuangtang against renal osteopathy. Method:One hundred and thirty healthy adult SD rats were randomly divided into five groups, namely normal group(<italic>n</italic>=10),high phosphorus group(<italic>n</italic>=30),model group(<italic>n</italic>=30),modified Liuwei Dihuangtang group(<italic>n</italic>=30) , and calcitriol group(<italic>n</italic>=30),and rats in each group were further classified based on three time points, namely 8,10, and 12 weeks. Rats in the normal group were fed with normal diet, the ones in the high phosphorus group with high phosphorus diet, and those in the other groups with adenine and high phosphorus diet for inducing renal osteopathy. Rats in the normal group,high phosphorus group, and model group were intragastrically administered with distilled water (10 mL·kg<sup>-1</sup>·d<sup>-1</sup>),the ones in the modified Liuwei Dihuangtang group with modified Liuwei Dihuangtang (2.556 g·kg<sup>-1</sup>·d<sup>-1</sup>) , and those in the calcitriol group with calcitriol (0.09 μg·kg<sup>-1</sup>·d<sup>-1</sup>). Result:Compared with the normal group and high phosphorus group at the weeks of 8,10 and 12,the model group displayed significantly elevated blood urea nitrogen(BUN),serum creatinine(SCr),serum phosphorus,iPTH,FGF23,renal interstitial fibrosis score, and FGF23 expression in renal and bone tissues, but lowered serum calcium and 1,25(OH)<sub>2</sub>D<sub>3</sub> and Klotho protein expression in renal and bone tissues(<italic>P</italic><0.05 ,<italic>P</italic><0.01). Compared with the model group at the weeks of 8,10 and 12, the modified Liuwei Dihuangtang and calcitriol both significantly decreased the serum BUN,SCr,serum phosphorus,iPTH, FGF23, tubulointerstitial semi-quantitative score, and FGF23 expression in renal and bone tissues, while increased the serum calcium,1,25(OH)<sub>2</sub>D<sub>3</sub>, and Klotho protein expression in renal and bone tissues (<italic>P</italic><0.05,<italic>P</italic><0.01). There was no significant difference in the above-mentioned indexes between the modified Liuwei Dihuangtang group and the calcitriol group at the same time point. Conclusion:Klotho-FGF23 axis is probably involved in renal osteopathy. The modified Liuwei Dihuangtang effectively improves renal function,alleviates pathological changes in renal and bone tissues,and regulates calcium and phosphorus metabolism to protect the bone, which is related to its regulation of Klotho-FGF23 axis.

ABSTRACT

Objective:To analyze the effects of proprioceptive neuromuscular facilitation (PNF) on balance, motor and activities of daily living (ADL) for stroke patients. Methods:The randomized controlled trials about the effects of PNF on motor, balance and ADL in stroke patients were retrieved from PubMed, Embase, CNKI, Wanfang data, and VIP, since establishment to December, 2019. The primary outcome measures were Berg Balance Scale (BBS), Fugl-Meyer Assessment (FMA) and modified Bathel Index (MBI). The secondary outcome measures were Functional Reach Test (FRT), Trunk Impairment Scale (TIS), and Timed 'Up and Go' Test (TUGT). The literatures were independently screened by two investigators, and the quality of the articles was evaluated using the Cochrane Library systematic review criteria, and meta-analysis was performed using RevMan 5.3. Results:A total of 13 articles were included with 786 stroke patients. PNF increased the score of BBS for sequelae patients (MD = 3.31, 95%CI 2.58 to 4.04, P < 0.001), FMA for recovery patients (MD = 8.31, 95%CI 5.68 to 10.97, P < 0.001); as well as MBI score (MD = 6.84, 95%CI 5.20 to 8.48, P < 0.001), FRT distance (MD = 1.11, 95%CI 0.39 to 1.84, P = 0.003) and TIS score (MD = 1.75, 95%CI 1.19 to 2.31, P < 0.001) for all the patients, and decreased TUGT time for sequelae patients (MD = -1.86, 95%CI -2.62 to -1.10, P < 0.001). Conclusion:PNF can significantly improve balance, motor and ADL for stroke patients. The effectiveness is various with the course of disease. More high-quality researches are needed.

ABSTRACT

With the improvement of surgical technique of heart transplantation and clinical application of potent immunosuppressant, the quantity of heart transplantation and the survival time of heart allograft have been significantly improved. However, a series of complications, such as right ventricular failure, ischemia-reperfusion injury, acute rejection, "Quilty lesion", infection and chronic rejection characterized by transplant coronary artery disease (TCAD) may still occur at different stages after heart transplantation. The application of endomyocardial biopsy (EMB) makes it possible to observe and understand the pathological features of multiple complications of heart allograft including rejection, which has become the most accurate diagnostic tool for postoperative complications. In this article, the brief history of heart allograft pathology, main postoperative complications and pathological diagnostic criteria, and cutting edge research progress on diagnostic criteria of rejection were illustrated, aiming to bring clinical benefits to more recipients undergoing heart transplantation.

ABSTRACT

BACKGROUND@#Breast cancer patients with ipsilateral supraclavicular lymph node metastasis (ISLNM) but without distant metastasis are considered to have a poor prognosis. This study aimed to develop a nomogram to predict the overall survival (OS) of breast cancer patients with ISLNM but without distant metastasis.@*METHODS@#Medical records of breast cancer patients who received surgical treatment at the Affiliated Cancer Hospital of Zhengzhou University, Jiyuan People's Hospital and Huaxian People's Hospital between December 21, 2012 and June 30, 2020 were reviewed retrospectively. Overall, 345 patients with pathologically confirmed ISLNM and without evidence of distant metastasis were identified. They were further randomized 2:1 and divided into training (n = 231) and validation (n = 114) cohorts. A nomogram to predict the probability of OS was constructed based on clinicopathologic variables identified by the univariable and multivariable analyses. The predictive accuracy and discriminative ability were measured by calibration plots, concordance index (C-index), and risk group stratification.@*RESULTS@#Univariable analysis showed that estrogen receptor-positive (ER+), progesterone receptor-positive (PR+), human epidermal growth factor receptor 2-positive (HER2+) with Herceptin treatment, and a low axillary lymph node ratio (ALNR) were prognostic factors for better OS. PR+, HER2+ with Herceptin treatment, and a low ALNR remained independent prognostic factors for better OS on multivariable analysis. These variables were incorporated into a nomogram to predict the 1-, 3-, and 5-year OS of breast cancer patients with ISLNM. The C-indexes of the nomogram were 0.737 (95% confidence interval [CI]: 0.660-0.813) and 0.759 (95% CI: 0.636-0.881) for the training and the validation cohorts, respectively. The calibration plots presented excellent agreement between the nomogram prediction and actual observation for 3 and 5 years, but not 1 year, OS in both the cohorts. The nomogram was also able to stratify patients into different risk groups.@*CONCLUSIONS@#In this study, we established and validated a novel nomogram for predicting survival of patients with ISLNM. This nomogram may, to some extent, allow clinicians to more accurately estimate prognosis and to make personalized therapeutic decisions for individual patients with ISLNM.

ABSTRACT

BACKGROUND@#The complement system plays an important role in the immune response to transplantation, and the diagnostic significance of peritubular capillary (PTC) C4d deposition (C4d+) in grafts is controversial. The study aimed to fully investigate the risk factors for PTC C4d+ and analyze its significance in biopsy pathology of kidney transplantation.@*METHODS@#This retrospective study included 124 cases of kidney transplant with graft biopsy and donor-specific antibody (DSA) testing from January 2017 to December 2019 in a single center. The effects of recipient pathological indicators, eplet mismatch (MM), and DSAs on PTC C4d+ were examined using univariate and multivariate logistic regression analyses.@*RESULTS@#In total, 35/124 (28%) were PTC C4d+, including 21 with antibody-mediated rejection (AMR), eight with renal tubular injury, three with T cell-mediated rejection, one with glomerular disease, and two others. Univariate analysis revealed that DSAs (P < 0.001), glomerulitis (P < 0.001), peritubular capillaritis (P < 0.001), and human leukocyte antigen (HLA) B eplet MM (P = 0.010) were the influencing factors of PTC C4d+. According to multivariate analysis, DSAs (odds ratio [OR]: 9.608, 95% confidence interval [CI]: 2.742-33.668, P < 0.001), glomerulitis (OR: 3.581, 95%CI: 1.246-10.289, P = 0.018), and HLA B eplet MM (OR: 1.166, 95%CI: 1.005-1.353, P = 0.042) were the independent risk factors for PTC C4d+. In receiver operating characteristic curve analysis, the area under the curve was increased to 0.831 for predicting PTC C4d+ when considering glomerulitis, DSAs, and HLA B eplet MM. The proportions of HLA I DSAs and PTC C4d+ in active antibody-mediated rejection were 12/17 and 15/17, respectively; the proportions of HLA class II DSAs and PTC C4d+ in chronic AMR were 8/12 and 7/12, respectively. Furthermore, the higher the PTC C4d+ score was, the more serious the urinary occult blood and proteinuria of recipients at the time of biopsy.@*CONCLUSIONS@#PTC C4d+ was mainly observed in AMR cases. DSAs, glomerulitis, and HLA B eplet MM are the independent risk factors for PTC C4d+.

ABSTRACT

Objective:Case mix index indicates the capacity of disease diagnosis and treatment, as well as the quality of health cares in related disciplines. Science and technology evaluation metrics represent the level of innovation and sustainable development of science and technology. Quality of health care and sustainable development are considered as two key evaluation indicators in the performance evaluation of national tertiary public hospitals. This study aimed to explore the effect of case mix index on the science and technology evaluation metrics.Methods:According to a cross-sectional design, the relationship between case mix index and science and technology evaluation metrics was analyzed in a tertiary public general hospital between 2017 and 2019.Results:In three years′ period time, the departments in top 100 disciplines of science and technology evaluation metrics had the case mix index 17% which was higher than other departments in non-top 100 disciplines ( P<0.05). In the multivariate analysis, higher case mix index increased a 2.29-fold higher probability to be in top 100 disciplines. They are under the receiver operative character curve between case mix index and top 100 disciplines in evaluation of departments was 0.716 ( P=0.001). Conclusions:Case mix index indicated the level of science and technology evaluation metrics and the clinical departments should improve the case mix index, service quality of health care and the motivation of sustainable development.

ABSTRACT

Ubiquitin is a widespread form of post-translational modification of proteins in cells, which plays an important role in regulating immune response, inflammatory response, cell connection, cell cycle, apoptosis, DNA damage repair and many other life processes. The ubiquitin modification of proteins is also reversible. Deubiquitinating enzymes regulate the life span or function of proteins through hydrolyzing polyubiquitin chains to deubiquitinate substrate proteins, thus playing a role in ubiquitin-mediated signal transduction pathways. Ovarian tumor-associated proteases (OTUs) belong to the cysteine family. It has been found that many members of the OTUs family are closely related to the regulation of viral infection. This paper reviewed the role and mechanism of OTUs in host antivirus response in recent years.

ABSTRACT

Objective:To explore the outcome of kidney transplantation from donation after cadaveric death(DCD)with high pathological Remuzzi score.Methods:From January, 2019 to December, 2019, 31 recipients of kidney allograft transplantation from marginal donors with Remuzzi score≥4 in preimplantation biopsy were retrospectively enrolled. They were divided into two groups of dual kidney transplantation(DKT, 14 cases)and single kidney transplantation(SKT, 17 cases). Median Remuzzi score of left kidney(5.05 in DKT group vs 4.92 in SKT group)or right kidney(5.26 vs. 4.58)was comparable. Dual donor kidneys were implanted into ipsilateral iliac fossa. Survival outcomes, kidney function, acute rejection episodes, incidence of delayed graft function(DGF)and proteinuria were recorded within Year 1 post-operation.Results:Proportion of male(92.9% vs. 52.9%, P<0.05)and recipient's body mass index(BMI, 23.93 vs. 21.09)were significant higher in DKT group than those in SKT group. One graft failure occurred in DKT group at Month 11 post-operation. The 1-year graft survival rate was 92.9% in DKT group and 1-year recipient survival rate both 100% in two groups. Mean 12-month serum creatinine[SCr, (164±37.7)μmol/L vs. (154.92±96.2)μmol/L]and estimated glomerular filtration rate[eGFR, (41.84±9.01) vs. (44.8±18.16)ml/(min·1.73m 2)]were comparable between two groups(both P>0.05). There was no occurrence of thrombosis resulting in graft loss. One-year incidence of acute rejection, rate of DGF(42.9% vs 41.2%)and proteinuria(57.1% vs. 41.2%)were comparable between two groups(both P>0.05). Conclusions:Through donor-recipient matching and dual kidney transplant allocation, short-term survival outcome of kidney allograft from marginal donors with high Remuzzi score≥4 is encouraging. However, long-term outcomes should be further examined.

ABSTRACT

Objective:To analyze a family clustering of coronavirus disease 2019 (COVID-19) associated with the exposure to an asymptomatic case, and to provide evidences of developing strategies for COVID-19 prevention. Methods:Epidemiological investigation was conducted on a COVID-19 family cluster (1 confirmed case and 2 asymptomatic cases). The specimens of the cases were tested for 2019 novel coronavirus nucleic acid with real-time fluorescence quantitative polymerase chain reaction. Results:The clustering epidemic occurred in a family. Two asymptomatic cases B and C (B’s son) had Wuhan residential history. After arrival in Beijing on January 24, 2020, B stayed in his mother's house. One family member A (B’s mother) developed the disease on February 7, 2020, while the other two family members D and E (B’s wife and brother) did not develop the disease, and they were managed as close contacts. Conclusion:Thisfamily COVID-19 clustering is induced by the exposure to an asymptomatic case. Identification of asymptomatic cases is very important for the control of COVID-19 epidemic.

ABSTRACT

The pathology of liver allograft biopsy is not only essential for the evaluation of liver donor, but also for the diagnosis and differential diagnosis of posttransplantation complications. With the development of liver transplantation in clinical practice, relevant studies of the pathological diagnosis of liver allograft complications have been deepened. Banff classification on liver allograft pathology have been gradually established within the international community. In China, pathological studies related to liver allograft pathology have been steadily carried out, and the pathological diagnostic basis of liver allograft pathology suitable for the clinical practice of liver transplantation in China has been gradually formed. This article reviews the history of Banff liver allograft pathology and major pathological lesions of liver allograft complications, aiming to provide reference for implementing pathological diagnosis of liver allograft pathology in China, assisting clinical diagnosis and targeted treatment of complications after liver transplantation, and further improving the survival of liver allograft and recipients.
