ABSTRACT
Pathogen detection is very important to improve the prognosis of patients with peritoneal dialysis-associated peritonitis. The paper reported a case of peritonitis caused by Ureaplasma parvum diagnosed by metagenomics next-generation sequencing(mNGS)technology. The patient was a middle-aged woman and hospitalized due to abdominal pain and muddy effluent. Anti-infective treatments such as ceftazidime and vancomycin were given but the effect was poor. The result of traditional culture was negative. Ureaplasma parvum was detected by mNGS. After using doxycycline,the patient's inflammation was controlled. It is suggested that mNGS plays an important role in the detection of the pathogens in peritoneal dialysis-associated peritonitis patients with negative culture. Through this case report and literature review,clinical experience is provided for the diagnosis and treatment in such patients.
ABSTRACT
This paper reports a case of peritonitis caused by Campylobacter fetus in a continuous ambulatory peritoneal dialysis (CAPD) patient. The patient was a middle-aged man, with chronic kidney disease stage 5 secondary to chronic glomerulonephritis, and had been on CAPD for 6 years. He was admitted to our department with a 7 day history of abdominal pain and cloudy effluent. Peritoneal effluent culture was negative and metagenomic next-generation sequencing suggested Campylobacter fetus. Intraperitoneal treatment with amikacin was failed. Peritoneal dialysis catheter was removed and hemodialysis treatment was performed. After treatment of erythromycin oral for 4 weeks, the patient's symptoms was improved and discharged.
ABSTRACT
Pituitary immune-related adverse events induced by programmed cell death protein 1 inhibitors in advanced lung cancer patients: A report of 3 cases SUMMARY Programmed cell death protein 1 (PD-1) and its ligand 1 (PD-L1) have been widely used in lung cancer treatment, but their immune-related adverse events (irAEs) require intensive attention. Pituitary irAEs, including hypophysitis and hypopituitarism, are commonly induced by cytotoxic T lymphocyte antigen 4 inhibitors, but rarely by PD-1/PD-L1 inhibitors. Isolated adrenocorticotropic hormone(ACTH) deficiency (IAD) is a special subtype of pituitary irAEs, without any other pituitary hormone dysfunction, and with no enlargement of pituitary gland, either. Here, we described three patients with advanced lung cancer who developed IAD and other irAEs, after PD-1 inhibitor treatment. Case 1 was a 68-year-old male diagnosed with metastatic lung adenocarcinoma with high expression of PD-L1. He was treated with pembrolizumab monotherapy, and developed immune-related hepatitis, which was cured by high-dose methylprednisolone [0.5-1.0 mg/(kg·d)]. Eleven months later, the patient was diagnosed with primary gastric adenocarcinoma, and was treated with apatinib, in addition to pembrolizumab. After 17 doses of pembrolizumab, he developed severe nausea and asthenia, when methylprednisolone had been stopped for 10 months. His blood tests showed severe hyponatremia (121 mmol/L, reference 137-147 mmol/L, the same below), low levels of 8:00 a.m. cortisol (< 1 μg/dL, reference 5-25 μg/dL, the same below) and ACTH (2.2 ng/L, reference 7.2-63.3 ng/L, the same below), and normal thyroid function, sex hormone and prolactin. Meanwhile, both his lung cancer and gastric cancer remained under good control. Case 2 was a 66-year-old male with metastatic lung adenocarcinoma, who was treated with a new PD-1 inhibitor, HX008, combined with chemotherapy (clinical trial number: CTR20202387). After 5 months of treatment (7 doses in total), his cancer exhibited partial response, but his nausea and vomiting suddenly exacerbated, with mild dyspnea and weakness in his lower limbs. His blood tests showed mild hyponatremia (135 mmol/L), low levels of 8:00 a.m. cortisol (4.3 μg/dL) and ACTH (1.5 ng/L), and normal thyroid function. His thoracic computed tomography revealed moderate immune-related pneumonitis simultaneously. Case 3 was a 63-year-old male with locally advanced squamous cell carcinoma. He was treated with first-line sintilimab combined with chemotherapy, which resulted in partial response, with mild immune-related rash. His cancer progressed after 5 cycles of treatment, and sintilimab was discontinued. Six months later, he developed asymptomatic hypoadrenocorticism, with low level of cortisol (1.5 μg/dL) at 8:00 a.m. and unresponsive ACTH (8.0 ng/L). After being rechallenged with another PD-1 inhibitor, teslelizumab, combined with chemotherapy, he had pulmonary infection, persistent low-grade fever, moderate asthenia, and severe hyponatremia (116 mmol/L). Meanwhile, his blood levels of 8:00 a.m. cortisol and ACTH were 3.1 μg/dL and 7.2 ng/L, respectively, with normal thyroid function, sex hormone and prolactin. All of the three patients had no headache or visual disturbance. Their pituitary magnetic resonance image showed no pituitary enlargement or stalk thickening, and no dynamic changes. They were all on hormone replacement therapy (HRT) with prednisone (2.5-5.0 mg/d), and resumed the PD-1 inhibitor treatment when symptoms relieved. In particular, Case 2 started with high-dose prednisone [1 mg/(kg·d)] because of simultaneous immune-related pneumonitis, and then tapered it to the HRT dose. His cortisol and ACTH levels returned to and stayed normal. However, the other two patients' hypopituitarism did not recover. In summary, these cases demonstrated that the pituitary irAEs induced by PD-1 inhibitors could present as IAD, with a large time span of onset, non-specific clinical presentation, and different recovery patterns. Clinicians should monitor patients' pituitary hormone regularly, during and at least 6 months after PD-1 inhibitor treatment, especially in patients with good oncological response to the treatment.

Objective:To compare the survival rate of secondary hyperparathyroidism (SHPT) patients with different dialysis modalities after parathyroidectomy (PTX), and analyze the influencing factors of survival prognosis.Methods:Clinical data of dialysis patients diagnosed with SHPT and treated with PTX in the First People′s Hospital of Foshan from April 2014 to May 2019 were retrospectively collected and analyzed. The patients were divided into hemodialysis (HD) group and peritoneal dialysis (PD) group according to preoperative dialysis modalities, and the differences in baseline clinical data and cardiac ultrasound results were compared between the two groups. Kaplan-Meier survival analysis was used to compare the difference in cumulative survival rate between the two groups. Multivariate Cox regression model was used to analyze the influencing factors of all-cause death. Receiver operating characteristic curve (ROC curve) was used to predict the risk of all-cause death.Results:A total of 99 patients were enrolled in this study, and 94 patients completed follow-up, including 23 patients who died. Compared with PD group ( n=45), HD group ( n=54) had higher dialysis age, blood pressure, intact parathyroid hormone, alkaline phosphatase, total heart valve calcification rate, mitral valve calcification proportion, interventricular septal thickness (IVST) and left ventricular mass index (all P<0.05). The median follow-up time was 46.00(32.75, 60.25) months. Kaplan-Meier survival analysis showed that there was no significant difference in cumulative survival rate between HD group and PD group (Log-rank test χ2=0.414, P=0.520). Multivariate Cox regression analysis showed that increasing age ( HR=1.066, 95% CI 1.017-1.118, P=0.008), systolic blood pressure>140 mmHg ( HR=2.601, 95% CI 1.002-6.752, P=0.049) and increasing IVST ( HR=1.269, 95% CI 1.036-1.554, P=0.021) were independent influencing factors for all-cause death in dialysis patients after PTX. ROC curve analysis results showed that the cut-off values of age, dialysis age and IVST for predicting all-cause death after PTX were 51.5 years old ( AUC=0.673, 95% CI 0.545-0.802, P=0.013) and 75.0 months ( AUC=0.654, 95% CI 0.528-0.780, P=0.027) and 13.5 mm ( AUC=0.680, 95% CI 0.557-0.803, P=0.010) respectively. The area under the ROC curve for age, dialysis age, IVST, left ventricular hypertrophy in combination with systolic blood pressure>140 mmHg in the prediction of all-cause death after PTX was 0.776(95% CI 0.677-0.875, P<0.001). Conclusions:There is no significant difference in cumulative survival rate between HD and PD patients with SHPT after PTX. Increasing age, systolic blood pressure>140 mmHg and increasing IVST are independent risk factors for all-cause death in dialysis patients with SHPT after PTX.
ABSTRACT
Ubiquitination is a unique protein post-translational modification in eukaryotic cells. It regulates a variety of physiological processes, such as protein homeostasis, cell cycle, immune response, DNA repair, and vesicle transport. In view of the importance of ubiquitin in live cells, pathogens have derived a series of effector proteins targeting the host ubiquitin process in the long-term evolutionary process, aiming to regulate the ubiquitin process in the host and render an internal environment suitable for the growth and reproduction of pathogens. Legionella pneumophila is a gram-negative bacterium that is responsible for Legionella pneumoniae pneumonia, causing fever and lung infection with a fatality rate of 15% ~ 30% in severe cases. The Dot / Icm type IV secretory system is the most important virulence system in the infection of Legionella pneumophila. In the process of infecting host cells, Legionella pneumophila uses this secretion system to secrete more than 330 effector proteins to assist bacterial survival, proliferation and escape in host cells. Several effector proteins of Legionella pneumophila regulate the host ubiquitination process directly or indirectly. Recent studies found that some effectors can mediate non-canonical ubiquitination of host proteins, which is different from the classical ubiquitination process. Here, we introduce the latest research progress of novel ubiquitination mediated by effecting proteins of Legionella pneumophila, providing a reference for understanding the important role of ubiquitination in the pathogenesis of Legionella pneumophila.
ABSTRACT
Immune checkpoint inhibitors (ICIs) have been used in treating a wide variety of cancers, but they challenge clinicians with a series of special immune related adverse events (irAEs) resulting from activated immune system. Since June 2018, when the first programmed cell death 1 (PD-1) inhibitor, nivolumab, was approved by the National Medical Products Administration (NMPA), abundant experience has been accumulated in coping with irAEs from PD-1 and PD-1 ligand 1 (PD-L1) blockade therapies. In October 2021, the first CTLA-4 inhibitor, ipilimumab, which has a different spectrum of irAEs was also approved by NMPA. The discrepancy in clinical features of pituitary irAEs is obvious between these two types of ICIs. Pituitary irAEs include hypophysitis and hypopituitarism. In this review of latest literature, we have summarized the incidence, possible mechanisms, time of onset, clinical presentations, hormone test, pituitary imaging, treatment strategies and recovery patterns of pituitary irAEs. By referring to domestic and foreign clinical guidelines, we have proposed practical suggestions for screening, diagnosing and treating pituitary irAEs.

ABSTRACT
Objective@#To find out the prognostic influencing factors of patients undergoing continuous renal replacement therapy (CRRT) for refractory acute left heart failure.@*Methods@#Through the medical system and hemodialysis system in Foshan First People's Hospital, all patients who received CRRT for refractory acute left ventricular heart failure from January 1, 2012 to January 1, 2019 were searched. All patients were divided into two groups by the final outcome: survival group and death group. Age, sex, initial mean arterial pressure (MAP), primary heart disease, use of vasoactive drugs, urine output before treatment, hemoglobin, serum creatinine, serum albumin, C-reactive protein(CRP), brain natriuretic peptide (BNP), cardiac ejection fraction (EF) and CRRT treatment time were analyzed to find out the prognostic influencing factors.@*Results@#A total of 130 cases were collected, including 96 cases in the survival group and 34 cases in the death group, with a total mortality rate of 26.15%. Compared to that in the death group, there were higher proportion of males (71.88% vs 50.00%, χ2=5.366, P=0.021), significantly higher initial MAP (t=4.677, P<0.001), much more urine output before treatment (Z=3.904, P<0.001), significantly higher serum creatinine (Z=2.866, P=0.004) , significantly lower hemoglobin (Z=-2.587, P=0.011), significantly shorter time of CRRT (Z=-3.447, P=0.001) in the survival group. Multivariate logistic regression analysis showed that female (OR=2.950, 95%CI 1.102-7.898, P=0.031) and higher levels of hemoglobin (OR=1.024, 95%CI 1.004-1.045, P=0.019) were the risk factors of death in patients undergoing CRRT for refractory acute left heart failure, while higher levels of mean arterial pressure before treatment (OR=0.959, 95%CI 0.930-0.989, P=0.008) and urine volume before treatment (OR=0.998, 95%CI 0.997-0.999, P=0.004) were the protective factors for patients' prognosis.@*Conclusion@#The mortality of patients with refractory acute left heart failure undergoing CRRT therapy is still very high. Female and higher level of hemoglobin are the risk factors for death, while more urine volume before treatment and higher MAP before treatment are protective factors for survival.

ABSTRACT
Objective:To determine whether the early stage platelet count can predict the outcome of peritoneal dialysis-associated peritonitis (PDAP).Methods:A retrospective cohort study was conducted by selecting PDAP patients who were hospitalized in the First People's Hospital of Foshan from January 2012 to January 2019. According to the final treatment outcome, the patients were divided into cured group and withdrawn group. The withdrawn group included patients who transferred to hemodialysis or died. Basic data on demography, blood routine examination, peritoneal fluid, biochemical indicators were compared between the two groups. Logistic regression analysis was used to analyze the withdrawn risk factors of PDAP.Results:There were 180 patients included in the study, including 112 cases in the cured group and 68 cases in the withdrawn group. Compared with the cured group, there were older age [(53.38±14.17) years old vs (48.41±13.04) years old, t=2.407, P=0.017], longer age of dialysis [(49.20±26.05) months vs (30.36±32.97) months, t=4.034, P<0.001], longer hospital stay [(23.88±11.50) d vs (17.80±3.95) d, t=5.133, P<0.001] and higher platelet count [(285.55±107.23)×10 9/L vs (234.90±74.03)×10 9/L, t=3.450, P=0.001], lower serum albumin [(31.72±7.47) g/L vs (35.40±4.93) g/L, t=-3.972, P<0.001] in the withdrawn group. Multivariate logistic regression analysis showed that longer dialysis age ( OR=1.012, 95% CI 1.007-1.024, P=0.015) and higher platelet count ( OR=1.013, 95% CI 1.004-1.026, P=0.008) were independent risk factors, and higher serum albumin ( OR=0.941, 95% CI 0.896-0.988, P=0.005) was an independent protective factor of withdrawal from peritoneal dialysis in PDAP patients. Conclusions:The long dialysis age, early high platelet count are independent risk factors and high serum albumin level is an independent protective factor for withdrawal from peritoneal dialysis in PDAP patients.
ABSTRACT
Objective:To investigate the hippocampal subfield volumes before and after taking hydrochloric donepezil in patients with mild Alzheimer's disease (AD). Methods:From January, 2017 to June, 2018, 25 mild AD patients accepted hydrochloric donepezil (treatment group), 25 patients accepted placebo (placebo group) and 25 age- and gender-matched healthy old people (control group) were scanned with magnetic resonance imaging (MRI) under 3D-T1 TFE sequence before and after a six-month treatment, and the automated segmentation of the hippocampus subfields was fulfilled with FreeSurfer and the hippocampus subfield volumes were compared, while the patients were assessed with Mini-Mental State Examination (MMSE). Results:Compared with the control group, the volumes of left CA1, CA2-3 and CA4-DG, and right CA1 and CA2-3 were reduced in patients before treatment (t > 2.294, P < 0.05). The volume of left CA4-DG increased in the treatment group compared with that of the placebo group after treatment (t = 2.196, P < 0.05), and the volume of bilateral CA1 and CA2-3 tended to increase but not significantly (t < 1.888, P > 0.065). The MMSE score was more in the treatment group than in the placebo group after treatment (t = 2.764, P < 0.05). Conclusion:The association with asymmetric atrophy in the hippocampal subfields has been found in mild AD patients, especially in left CA4-DG, which may be used as a valuable marker for diagnosis and evaluation for treatment at early stage.

ABSTRACT
Objective To focus on CT classification and clinical significance for minimal lung adenocarcinoma(MIA),to improve the knowledge of this kind of lung adenocarcinoma.Methods 51 cases of MIA confirmed by histopathology were retrospectively evaluated in our hospital,which were analyzed and classified by CT manifestation.Results Of the 51 patients,according to CT features ,lesions were divided into three types:pure ground-glass nodule (pGGN)(34 cases),mixed ground-glass nodule(mGGN)(8 cases),Part-solid GGN (9 cases).The maximum diameter of pGGN ranged from 0.62-2.41 cm (1.01 cm±0.36 cm),the overall density was uniform and the CT value-plus ranged from 150-512 HU (266 HU±81 HU).mGGN showed scattered punctate or rounded,oval shaped high density in GGN in lung window,which was not visible in mediastinal window.Part-solid GGN showed solid component in both lung window and mediastinal window and the longest average diameter of the solid component ranged from 0.02-0.49 cm(0.2 cm±0.16 cm).While no statistical differences were found between the three types in shape,margin,air bronchogram,pleural retraction,vessel dilatation, but lobular,burr and pleural retraction were observed more frequently in Part-solid GGN and mGGN than that in pGGN.In addition, 50% of lobulation were deep lobulation,which was showed statistical difference between pGGN and mGGN/Part-solid GGN groups. Conclusion MIA has multiple CT manifestations,the morphology and size of solid component plays an important role in the diagnosis of MIA. For pGGN,lesion size and CT value-plus should be considered when diagnosing MIA.

ABSTRACT
Objective To analyze the epidemiological situation of human intestinal nematode infections in Nanjing City from 2006 to 2015,so as to provide the reference for formulating prevention and control measures. Methods The surveillance data of human intestinal nematode infections in Nanjing City from 2006 to 2015 were collected and analyzed statistically. Results From 2006 to 2015,98804 person-times of residents were surveyed in Nanjing City,and 465 person-times of residents were de-tected with intestinal nematode infections. The highest infection rate was in 2006(1.97%),and the lowest in 2013 and 2015 (both 0.05%). Moreover,the positive rate of human intestinal nematode infections showed a significantly declining trend in total (χ2=552.19,P<0.001). Meanwhile,the numbers of Ascaris lumbricoides,hookworm and Trichuris trichura cases were 329, 98 and 25 respectively,and the infection rates were 0.33%,0.10%and 0.03%respectively. Among them,443 cases had mild infection intensity (98.66%). There were 462 cases of single-infection (99.35%),and 3 of co-infection of two parasites (0.65%). From 2006 to 2015,92539 person-times of children under 12 years old were surveyed for Enterobius vermicularis in-fection and 352 cases were detected with E. vermicularis infection. Moreover,the positive rate showed a significantly decreasing trend in total(χ2=147.94,P<0.001). Conclusions The control effect of human intestinal nematode infections in Nanjing City is remarkable. However,the surveillance and health education in key groups still should be strengthened,and the preven-tion and control programs should be adjusted promptly to further consolidating the effectiveness of intestinal nematode disease prevention and control.

Objective To investigate the clinical therapeutic effects of bone cement-augmented pedicle screw fixation for cement vertebrae refractures with lower limb neurological symptoms after percutaneous kyphoplasty (PKP) in elderly patients with osteoporotic thoracolumbar compression fractures.Methods A total of 123 elderly patients with osteoporotic thoracolumbar compression fractures underwent PKP from December 2013 to December 2016 were retrospectively analyzed by case series study.Twelve patients had vertebral refracture with compression of the spinal cord or cauda equina which resulted in lumbosacral and leg pain,numbness and disability of ambulation and there were five males and seven females,with age of (69.2 ± 7.1) years.Injured vertebrae was located at T12 in five cases,at L1 in five and at L2 in two.Bone cement-augmented pedicle screw fixation through a standard posterior approach was utilized to treat all the 12 patients.Visual analogue scale (VAS),Oswestry disability index (ODI),anterior vertebral height compression ratio,and kyphotic angle at the preoperative time,one week postoperatively and last follow-up were recorded and compared.Intraoperative and postoperative complications were also recorded.Results The mean duration of follow-up in all the patients was 26.7 months (range,12-36 months).Intraoperative nerve injury,dural tear,leakage of bone cement,bone cement toxicity reaction,and pulmonary embolism were not observed during the surgery.The postoperative radiographs for all the 12 patients showed that the bone cement was distributed in cancellous bone and around the screw appropriately where there was no cement leakage out of the vertebral body or pedicle.Compared with preoperative scores,the average low back pain VAS,leg pain VAS and ODI at postoperative one week were improved by (2.2 ± 0.7) points,(2.2 ± 0.4) points and (33.2 ± 8.9) points,respectively (P < 0.01).Anterior vertebral height compression ratio was decreased from preoperative (71.5 ± 11.7) % to (18.7 ± 10.3) % at postoperative one week (P < 0.01).The mean kyphotic angle was corrected from preoperative (28.3 ± 7.6) ° to (7.1 ± 2.3) ° at postoperative one week (P < 0.01).The symptoms of lumbar pain,and numbness and weakness of lower limbs were improved significantly.There was no statistically significant difference of all the parameters between the last follow-up evaluation and one week post-operatively (P > 0.05).Conclusion For elderly patients with spinal cord or cauda equina nerve compression symptoms after PKP for osteoporotic thoracolumbar compression fractures,the usage of posterior approach bone cement-augmented pedicle screw fixation can effectively correct kyphosis,relieve neurological symptoms and restore spinal stability.
ABSTRACT
Objective: To investigate the synergistic antibacterial effect of Callicarpa nudiflora associated with Vancomycin Hydrochloride on the pneumonia model rats infected by methicillin-resistant staphylococcus aureus (MRSA), and to provide a safer and more effective treatment of clinical ideas for the treatment of infections caused by MRSA. Methods: Totally 80 NIH female rats were randomly divided into eight groups, ten rats as the control group, and 200 μL MRSA (1 × 108 CFU/ mL) bacteria was dropped in the left nasal cavity of the remaining rats to produce infected animal model. The administration with drug respectively by group was continued for 10 d. The common state including activity and intake of water and food were observed and noted. After administration for 10 d, the count of leucocyte, microbial load, and histopathological change of lung were observed. Results: Compared with the model group, the absolute value of leucocyte and microbial load of association of C. nudiflora and Vancomycin Hydrochloride were reduced signicantly (P < 0.05). The pathological damage alleviated significantly. Conclusion: Association of C. nudiflora and Vancomycin Hydrochloride has the synergistic antibacterial effect towards MRSA, which can improve the curative effect of antibiotics and shorten the period of treatment.
