The medical humanistic spirit is an ethical concept which takes people-oriented,life-loving,and a sustainable development of human physical and mental health as its ideal value.However,since the modern society is filled with technological doctrines,utilitarianism and market-oriented behaviors,making the humanistic spirit in medical education weakened,resulting in unethical action of healthcare services,disordered healthcare services,and the imbalance between physicians and patients.This paper studies the question of modern medicine brought about by the loss of humanistic spirit,discusses the "humanistic" feature of new healthcare reform,and bring forward a medical personnel training mode which stresses humanistic spirit.

Objective To study the characteristic and management method of steroidogenic diabetes in patients with rheumatic disease. Methods The follow-up data of steroidogenic diabetes in 38 patients with rheumatic disease were analyzed retrospectively. Results The nosogenesis of steroidogenic diabetes and fast blood sugar level was related with steroid dosage, using time, age, obesity and hypertipoidemia. The blood-fasting sugar level was not so obviously increased. Blood sugar at bedtime was (24.40±5.92)mmol/L,before breakfast was (9.52±3.64)mmol/L, after breakfast was (20.38±7.19)mmol/L, before lunch was(10.69±3.23)mmol/L, after lunch was (21.81±6.92) mmol/L, before dinner was (12.17±3.63)mmol/L. There was significant difference between blood sugar at bedtime and that in others (P<0.01 or<0.05). Most patients needed insulin to control blood sugar. Decreasing the daily dosage of steroid might be beneficial to the reduction of corticosteroid induced diabetes. Most patients could stop insulin injection when the daily dosage of steroid decreased to a certain level. Conclusions The prescription of corticesteroid in rheumatic diseases can cause temporal increase of blood sugar. Intensive follow-up aad blood sugar monitor is important for the diagnosis of steroidogenic diabetes. Promptly administration of insulin is required for blood sugar control.

Diabetic neuropathic pain(DNP)is one of the most common complications in clinical, which influenced patients’ daily functions greatly, without clear mechanisms and effective methods.P2X3 receptors play a pivotal role in the formation, transmission and conduction of pain under neuropathic pain models, associated with peripheral sensory nerve excitability enhancement.This paper focuses on the establishment of DNP models, and the effects of P2X3 receptors in diabetes mellitus.

Objective To study the therapeutic effect of rheum(Chinese herbal medicine) preparation made by using ultrasonic technique on pro-inflammatory cytokines and sepsis in rats.In order to offer novel measure for the treatment of critically ill patients.Methods Firstly, rheum sterile solution was prepared through ultrasonic technique.Secondly, fifty healthy male SD rats were randomly(random number) divided to CLP group and rheum group.Moderate degree of sepsis model was established by using cecal ligation and puncture(CLP).Rats in group rheum received the liquid rheumpreparation via intragastric administration, while rats in group CLP received saline instead.The 7-day survival rate was recorded and was compared between two groups.In addition, another fifty-four rats were randomly(random number) divided to sham group, CLP group and rheum group(n=18 in each group).CLP was performed to induce sepsis in CLP group and rheum group.Then rats in rheum group received rheum sterile solution via intragastric administration, while rats in CLP group received saline instead.At 12 hours, 24 hours and 48 hours after modeling, six rats in each group were randomly sacrificed.Serum TNF-α and HMGB1 levels were detected by ELISA method.Levels of RAGE, HMGB1 and NF-κB P65 in small intestine were detected by Western Blot.Results Level of anthraquinones extracted from rheum by ultrasonic technique was higher than that by conwentional decoction method.The 7-day survival rate of rats in rheum group(76%) was higher than that in CLP group(48%)(P<0.05).Compared with sham group, serum TNF-αand HMGB1 levels in CLP group and rheum group were significantly increased(P<0.05).TNF-α was significantly lower in rheum group than that in CLP group at each interval(P<0.05).At 12 hours after modeling, there was no significant difference in serum HMGB1 level between CLP group and rheum group(P>0.05).At 24 hours and 48 hours after modeling, serum HMGB1 levels were significantly lower in rheum group than those in CLP group(P<0.05).Compared with sham group, protein levels of HMGB1, RAGE and NF-κB in small intestine were elevated in CLP group and rheum group at 48 hours after modeling(P<0.01), while protein levels of above biomarker were higher in CLP group than those in rheum group(P<0.05).Conclusions Rheum sterile solution could down-regulate the level of pro-inflammatory cytokines, modulate the inflammatory response, and improve the survival rate in rats with sepsis.

Objective To observe the effect of recombinant human tumor necrosis factor receptor-Fc fusion protein (rhTNFR-Fc, etanercept) on the expression of transforming growth factor-β1 (TGF-β1) in bleomycin induced interstitial lung disease of rats. Methods Forty-five male Sprague-Dawley (SD) rats were randomly divided into three groups (control group, model group and rhTNFR-Fc treatment group, 15 rats in each), on the 7th, 14th and 28th days, five rats of each group were killed. The lungs were incised to make pathological sections which were stained with HE and Masson, and the expression of TGF-β1 was detected by immunohistochemical technique. Results There was no collagen deposition, alveolitis and fibrosis changes in the control group. The alveolitis and fibrosis of the treatment group was less severe than that in the model group (P<0.01). The expression of TGF-β1 in the model group was significantly higher than that in the control group (P<0.01). In the 7th and 14th days, the expression of TGF-β1 in the treatment group was signific-antly higher than that in the control group (P<0.01). Although that in the 28th day was a slightly higher but no statistical significance (P>0.05) could be detected. In the treatment group, the expression of TGF-β1 was lower in the 7th day (P>0.05) and was significantly lower in the 14th and 28th days than that in the model group (P<0.01). Conclusion Recombinant human tumor necrosis factor receptor-Fc fusion protein can alleviate the severity of alveolitis and pulmonary fibrosis induced by Bleomycin-A5 in rats, which may be due to the inhibition of TGF-β1 overexpression.

Objective To investigate the effects of low frequency electroacupuncture on the P2X3 receptor expres-sion in dorsal root ganglion ( DRG) of rats with type II diabetic neuropathic pain. Methods Part 1:Fifty normal SD rats were randomly divided into normal group (8 rats) and model group (42 rats). The rat model of type II diabetic neuropathic pain was generated by high fat and high sugar diet with a single intraperitoneal injection of streptozotocin ( STZ, 35 mg/kg) . 2 Hz electroacupuncture was administered at ipsilateral acupoints Zusanli and Kunlun for consecutive 7 days. Insulin sensitivity index ( ISI) was measured at 0 w and 5 w, and fasting plasma glucose ( FPG) was measured at 0 w, 5 w, and 7 w. Paw withdrawal threshold (PWT) was measured by mechanical pain threshold, and P2X3 receptor was determined by immunofluorescence. Part 2:Twelve rats with diabetic neuropathic pain (DNP) were divided into EA + vehicle group (6 rats) and EA + αβ?meATP group (6 rats). Rats in the two groups received the same EA treatment as Part 1. Rats in the EA + αβ?meATP group were injected with P2X3 receptor agonistαβ?meATP (0. 6μmol/L, 100μL) into the ventral sur?face of each hind paw every time before EA treatment. Rats in the EA + vehicle group received the same dose of vehicle ( PBS buffer) as a control. Pain threshold of the rats were measured. Results ① Compared with the normal group, the ISI levels of the rats in DNP group was significantly decreased after 5 weeks of the high?fat high?sugar diet (P < 0. 01). Two weeks after STZ injection, the fasting plasma glucose levels in the rats receiving STZ were significantly elevated ( P <0. 01 ) . The type 2 diabetes model was established with a successful rate of 69. 04%. ②PWTs:The PWTs of rats in DNP group were reduced compared with rats in the normal group (P < 0. 01), indicating that the type 2 DNP model was suc?cessfully established. Compared with the PWTs of DNP?controlled rats, the 2 Hz electroacupuncture significantly increased bilateral PWT of rats subjected to DNP from day 3 after treatment (P < 0. 01). P2X3 receptor agonistαβ?meATP greatly reduced bilateral PWT of EA?treated DNP rats compared with that of the EA + vehicle group (P < 0. 01). ③The immu?nofluorescence essay showed that P2X3 receptor expression in bilateral L5 DRGs in the DNP group was significantly in?creased as compared with that in the normal group ( P < 0. 01 ) . The increases were inhibited by 2 Hz EA in L5 DRGs compared with the DNP group (P < 0. 01). Conclusions 2Hz electroacupuncture can effectively treat the type II diabet?ic neuropathic pain by decreasing the expression of L5 DRG P2X3 receptors in rats.

Objective To analyze the clinical characteristics of respiratory involvement in relapsing polychondritis(RPC). Methods The clinical data of 38 patients with respiratory (larynx, trachea and bronchus) involvement in RPC were retrospectively analyzed. Results The incidence of respiratory involvement in patients with RPC was 51.35%(38/74), and the most common symptoms were cough, wheezing, chest tightness and dyspnea. The incidences of erythrocyte sedimentation rate (ESR) increasing, C- reactive protein (CRP) increasing, fibrinogen increasing, D- dimer increased and rheumatoid factor (RF) positive in patients with respiratory involvement were significantly higher than those in patients without respiratory involvement: 47.37% (18/38) vs. 30.56% (11/36), 52.63% (20/38) vs. 33.33% (12/36), 31.58% (12/38) vs. 25.00% (9/36), 21.05% (8/38) vs. 13.89% (5/36) and 36.84%(14/38) vs. 5.56% (2/36), and there were statistical differences (P<0.05). CT was the main method to discover the respiratory involvement, and MRI could detect early cartilage inflammation lesions. Laryngoscope and bronchoscope could early detect mucosa and cartilage damage. Pathology was given priority to lymphocytes and neutrophils infiltration. Some patients had epithelium metaplasia and even canceration. Primary treatment methods were glucocorticoids combined with immunosuppressant. Airway stenosis and infection was the main factors influencing the prognosis of patients. Conclusions The respiratory involvement is not uncommon in RPC, and early CT, MRI, laryngoscope and bronchoscope examination is an important means of early diagnosis.Early glucocorticoid combined immunosuppressive therapy is the key to achieve good prognosis.

Objective:To study the clinical features of infective endocarditis (IE) with positive anti-neutrophil cytoplasmic antibodies (ANCA) in order to improve the level of diagnosis and treatment.Methods:Eighteen IE cases with positive ANCA admitted to the First Affiliated Hospital of Zhengzhou University from June 2016 to July 2021 were collected. The demographic information, clinical symptom, laboratory tests, imaging examinations, treatment and clinical outcomes were analyzed retrospectively. Statistical program for social sciences (SPSS) 20.0 statistical software was used for analysis. Enumeration data were expressed as the number of cases and percentage (%), and measurement data were expressed as Mean± SD. Results:Twelve cases were male and 6 cases were female, with an average age of (50±16) years. Sixteen patients had positive PR3-ANCA, in which 2 cases had positive myeloperoxidase (MPO)-ANCA. The major clinical manifestations included fever (88.9%, 16/18), anemia (72.2%, 13/18), splenomegaly (44.4%, 8/18), cardiac murmur (33.3%, 6/18), arthralgia (22.2%, 4/18), liver damage (22.2%, 4/18), thromboembolic events (16.7%, 3/18), Osler's node (11.1%, 2/18) and renal dysfunction (11.1%, 2/18). Higher C-reactive protein (CRP), erythrocyte sedimentation (ESR) and procalcitionin (PCT) were detected in 83.3% (15/18) patients. The positive rate of blood culture was 50.0%(9/18) and streptococcus was the most common pathogen (77.8%, 7/9). Echocardiograms of all patients showed abnormal vegetation, most commonly involving the mitral valve (66.7%, 12/18) and aortic valve (33.3%, 6/18). Two patients were misdiagnosed as ANCA associated vasculitis (AAV), but the other one was diagnosed as AAV with IE as the first manifestation. Except for one case who died of multiple organ failure, all cases reached clinical recovery after surgery and antibiotic therapy.Conclusion:IE patients with positive ANCA may present with the clinical manifestations similar to AAV. We should highly alert to avoid misdiagnosis and treatment.

Objective:To study the clinical and immunological features of two case of rare antisynthetase syndrome (ASS), so as to improve the level of diagnosis and treatment.Methods:Two cases with rare antisynthetase syndrome admitted to the First Affiliated Hospital of Zhengzhou University from July 2020 to August 2022 were collected.Results:The two rare ASS were anti-Zo antibody and anti-Ha antibody positive patients, both of which had interstitial lung disease (ILD) as the main clinical manifestation and positive anti-Ro52 antibody. Two rare antisynthetase autoantibodies manifested cytoplasmic ANA indirect immunofluorescence (IIF) staining pattern, but it is different from the cytoplasmic dense speckled pattern of several common ASS antibodies. After treatment with glucocorticoids and immunosuppressants, case 1 died of respiratory failure due to a long course of disease and late diagnosis, the lung lesions of case 2 improved significantly.Conclusion:When encountering the cytoplasmic ANA fluorescent pattern in ILD patients, especially with anti-Ro52 antibody, it is necessary to screen more myositis specific antibodies to rule out the possibility of rare ASS.
