Objective:To investigate the effect of erigeron breviscapus (EBHM) on ocular hypertension and the protective effect of retinal ganglion cells (RGCs) in rats by regulating mitogen activated protein kinase (MAPK) signaling pathway.Methods:Sixty male Sprague-Dawley rats were divided into control group, model group, low-dose EBHM group (group A), medium-dose EBHM group (group B), and high-dose EBHM group (group C) by random number table method. There were 12 rats in the group, the left eye was used as the experimental eye. The rats of model group, group A, group B, and group C were infused with normal saline through the anterior chamber to construct an acute ocular hypertension model; the control group was given general anesthesia only. Then, 2-30 days after modeling, rats in the control group and model group were given 3 ml of normal saline once a day; rats in group A, group B, and group C were given 0.30, 0.45, and 0.60 g/100 g EBHM by intragastric administration, respectively, 1 time/d. The rat intraocular pressure was measured before modeling and 1, 14, and 30 days after modeling, and the proportion of high intraocular pressure model was measured. Thirty days after modeling, hematoxylin-eosin (HE) staining was used to observe the pathological changes of retinal tissue; immunofluorescence staining was used to detect the changes in the number of RGCs; real-time fluorescent quantitative polymerase chain reaction (RT-qPCR) was used to detect p38 in the retinas of rats in each group. The relative expression of MAPK and Caspase-3 mRNA; western blot was used to detect p38MAPK and phosphorylation in the retina of rats in each group relative expression of phosphorylate-p38MAPK (p-p38MAPK) and Caspase-3 protein. One-way analysis of variance was used for multi-sample comparison, and SNK-q test was used for comparison between two samples. Results:One day after modeling, none of the rats in the control group developed acute ocular hypertension, and the other groups were successfully modeled. Compared with the model group, the rates of acute ocular hypertension at 14 days after modeling in groups B and C were lower ( χ2=98.701, P<0.05), and the rates of acute ocular hypertension at 30 days after modeling in groups A, B, and C were 0. There was no statistically significant difference in the rates of acute ocular hypertension between 14 and 30 days after modeling in the A, B, and C groups ( P>0.05). The results of HE staining showed that the structure of the retina in the control group was complete, and the layers were clearly visible; the RGCs count was not abnormal, and the morphology was plump and round. The retina of rats in the model group became thinner; the number of RGCs was greatly reduced, the morphology was vacuolated, and the arrangement was sparse. The retina of rats in groups A, B, and C became thicker, and the number of RGCs increased, and the retina structure in group C was better restored. The results of immunofluorescence staining showed that the RGCs counts of rats in groups A, B, and C were higher than those in the model group, and the difference was statistically significant ( F=297.514, P<0.05); pairwise comparison between groups, group A was lower than that of group B and C Group ( q=2.842, 5.263), group B was lower than group C ( q=2.457), the difference was statistically significant ( P<0.05). The results of RT-qPCR and Western blot showed that compared with the model group, the relative expression of Caspase-3 mRNA ( F=267.912) and protein ( F=692.279) and the relative expression of p-p38MAPK protein in the retina of rats in groups A, B and C. The expression level ( F=150.061) all decreased, and the difference was statistically significant ( P<0.05); pairwise comparisons between groups showed that Caspase-3 mRNA ( q=6.977, 15.642) and protein ( q=6.997, 15.642) relative expression levels and p-p38MAPK protein ( q=12.443, 24.358) relative expression levels are lower than groups A and B, group B was lower than group A ( q=11.678, 12.471, 10.204), the difference was statistical academic significance ( P<0.05). Conclusions:EBHM can significantly reduce intraocular pressure in rats with acute ocular hypertension, increase RGCs counts, and reduce retinal damage. Its regulatory mechanism may be related to the MAPK pathway.

OBJECTIVE:To observe the efficacy and safety of Sanjiao fuzheng mixture combined with concurrent chemoradiotherapy of paclitaxel and nedaplatin in the treatment of local advanced non-small cell lung cancer (NSCLC). METHODS:A total of 68 patients with local advanced NSCLC selected from our hospital during Jan. 2015 to Jan. 2017 were divided into control group and observation group according to random number table,with 34 cases in each group. Control group was given Paclitaxel injection 135 mg/m2 intravenously,d1+Nedaplatin for injection 75 mg/m2 intravenously,d3,21 d as a treatment course,for 2 courses;routine fractionated intensity modulated radiation therapy,2 Gy each time,5 times a week,60-70 Gy in total;given 2 cycles of primary chemotherapy continuously after radiotherapy. Observation group was additionally given Sanjiao fuzheng mixture 250 mL/d,divided into 3 times,till the end of treatment,on the basis of control group. Clinical efficacies were observed in 2 groups. The levels of nutritional indexes (BMI,PAB,ALB,Hb) and tumor markers (SCC-Ag,CEA,TK1, CYFRA21-10) before and after treatment were observed. The occurrence of ADR were recorded. RESULTS:There was no statistical significance in the total effective rate between 2 groups (observation group 82.35％ vs. control group 73.53％)(P>0.05). After treatment,the levels of BMI,PAB,ALB and Hb in 2 groups were significantly lower than before treatment,but the observation group was significantly higher than the control group. The levels of SCC-Ag,CEA,TK1 and CYFRA21-1 in 2 groups were significantly lower than before treatment,and the observation group was significantly lower than the control group,with statistical significance (P<0.05). The incidence of Ⅲ-Ⅳ degree aleucocytosis,Ⅰ-Ⅱ degree hemoglobin reduction and thrombocytopenia in observation group were significantly lower than control group, with statistical significance (P<0.05). CONCLUSIONS:The efficacy of Sanjiao fuzheng mixture combined with concurrent chemoradiotherapy of paclitaxel and nedaplatin is similar to that of concurrent chemoradiotherapy of paclitaxel and nedaplatin for localadvanced NSCLC,which can improve nutritional status significantly,and reduce the incidence of ADR.

Objective:To analyze the clinical feature of adult patients with infection-associated hemophagocytic syndrome (IAHS), and to improve the ability of clinicians to diagnose and treat IAHS.Methods:A retrospectively study was performed. The clinical data of 32 adult patients with IAHS admitted to the intensive care unit (ICU) of the First Affiliated Hospital of Kunming Medical University from July 2014 to November 2019 were analyzed. The general data, clinical manifestations, laboratory results, imaging findings, pathogen and clinical outcomes were collected, and the patients were divided into survival group and death group according to the 28-day prognosis. The clinical data between the two groups were compared, and multivariate Logistic regression analysis was used to analyze the variables with statistical significance in univariate analysis. The receiver operating characteristic (ROC) curve was drawn to analyze the predictive value of variables with statistical significance in univariate analysis for 28-day prognosis of adult patients with IAHS.Results:Among 32 adult patients with IAHS, there were 17 males (53.1%) and 15 females (46.9%). Eighteen patients were bacterial infection, most of which were Acinetobacter baumannii and Escherichia coli; 14 patients were viral infection, mainly EB virus; and the overall 28-day mortality was 62.5% (20/32). ① Compared with the survival group ( n = 12), the levels of white blood cell (WBC), neutrocyte (NEU), lymphocyte (LYM), platelet (PLT) and oxygenation index (OI) in the death group ( n = 20) were lower, while the levels of aspartate aminotransferase (AST), K +, serum ferritin (SF) and lactate dehydrogenase (LDH) were higher [WBC (×10 9/L): 3.90±3.36 vs. 9.57±6.48, NEU (×10 9/L): 2.69±2.09 vs. 7.01±6.34, LYM (×10 9/L): 0.36 (0.23, 0.84) vs. 1.24 (0.61, 2.36), PLT (×10 9/L): 51.15±27.60 vs. 108.42±80.26, OI (mmHg, 1 mmHg = 0.133 kPa): 134.0 (77.5, 192.0) vs. 292.0 (187.0, 329.0), AST (U/L): 254.00 (67.80, 452.50) vs. 85.50 (38.38, 111.25), K + (mmol/L): 4.06 (3.65, 4.51) vs. 3.52 (3.26, 3.76), SF (μg/L): 6 290.0 (1 851.0, 13 904.8) vs. 1 777.1 (1 228.5, 3 486.3), LDH (μmol·s -1·L -1): 19.3 (11.9, 27.0) vs. 9.8 (6.9, 11.1), all P < 0.05]. In death group, duration of having a fever after admission was prolonged [days: 13.5 (9.0, 17.2) vs. 6.0 (2.5, 8.0), P < 0.05] and the incidence of cyanosis was higher (40.0% vs. 0%, P < 0.05). There was no significant difference in other indicators between the two groups. ② Multivariate Logistic regression analysis showed that low OI combined with high LDH were risk factors for 28-day mortality of adult patients with IAHS [odds ratio ( OR) was 0.967 and 1.007, respectively, both P < 0.05].③ It was shown by ROC curve analysis that WBC, NEU, AST, SF, LDH and OI had predictive value for 28-day prognosis of adult patients with IAHS (both P < 0.05), and the area under ROC curve (AUC) of OI and LDH was higher, that was both 0.847. When the best cut-off of OI was 145.5 mmHg, the sensitivity was 63.2%, and the specificity was 100%. When the best cut-off of LDH was 13.4 μmol·s -1·L -1, the sensitivity was 72.2%, and the specificity was 91.7%. Conclusion:OI < 145.5 mmHg, and LDH > 13.4 μmol·s -1·L -1 were significant predictors for poor 28-day prognosis of adult patients with IAHS.

Objective: To explore the feasibility of difference between hematocrit and albumin (HCT-ALB) to evaluate the severity in patients with severe scrub typhus (Tsutsugamushi disease). Methods: The clinical data of 408 patients with scrub typhus in 37 hospitals located in 15 prefectures of Yunnan Province from January 1st, 2017 to December 31st, 2018 were retrospectively collected. The patients were divided into the non-severe scrub typhus disease group (n = 265) and the severe scrub typhus disease group (n = 143) according to the diagnostic criteria. Volunteers attending Kunming City Medical Center in Yunnan Province for routine physical examination were enrolled as healthy control group (n = 230). HCT, ALB, lactate dehydrogenase (LDH), uric acid (UA), and acute physiology and chronic health evaluationsⅡ(APACHEⅡ) and sequential organ failure assessment (SOFA) within 24 hours after admission were collected. HCT-ALB difference was calculated. Pearson method was used to analyze the correlation between HCT-ALB difference and LDH, UA, APACHEⅡ and SOFA scores in patients with severe scrub typhus disease; the receiver operating characteristic (ROC) curve was used to analyze the value of HCT-ALB difference in the diagnosis of severe scrub typhus disease. Results: ① There was no significant difference in gender composition between patients with non-severe scrub typhus disease group and severe scrub typhus disease group, but the age of the severe scrub typhus disease group was significantly higher than that of the non-severe scrub typhus disease group (years old: 53.57±15.23 vs. 35.03±23.47, P < 0.01). ② Compared with the healthy control group, the HCT, ALB of the non-severe scrub typhus disease group and severe scrub typhus disease group were significantly decreased [HCT: (36.54±6.82)%, (38.13±7.60)% vs. (46.20±4.42)%; ALB (g/L): 35.53±5.87, 26.90±6.10 vs. 47.75±4.28, all P < 0.01], and the HCT-ALB difference was significantly increased (5.28±3.90, 11.26±6.62 vs. 1.55±5.32, both P < 0.01). Compared with the non-severe scrub typhus disease group, the HCT of the severe scrub typhus disease group was significantly increased [(38.13±7.60)% vs. (36.54±6.82)%, P < 0.01], the ALB was significantly decreased (g/L: 26.90±6.10 vs. 35.53±5.87, P < 0.01), and the HCT-ALB difference was significantly increased (11.26±6.62 vs. 5.28±3.90, P < 0.01). ③ Pearson correlation analysis showed that HCT-ALB difference was positively correlated with LDH and UA in patients with severe scrub typhus disease (r values were 0.316 and 0.284, respectively, both P < 0.01), and negatively correlated with APACHEⅡ score and SOFA score (r values were -0.229 and -0.198, respectively, both P < 0.05). ④ ROC curve analysis showed that the area under the curve (AUC) of HCT-ALB difference in the diagnosis of severe scrub typhus disease was 0.786, standard error was 0.024, P = 0.000, and 95% confidence interval (95%CI) was 0.739-0.832. When the best diagnostic value was 8.56, the sensitivity was 81.1%, the specificity was 60.8%, and the Youden index was 0.419. Conclusions HCT-ALB difference is an indicator to evaluate the severe scrub typhus disease. When HCT-ALB difference is above 8.56, it can be used as an indicator to identify severe scrub typhus disease.

To analyze the clinical characteristics of severe tsutsugamushi disease, and to improve the ability of clinicians to recognize severe cases. Methods The clinical data of patients with tsutsugamushi disease from January 1st, 2017 to December 31st, 2018 in hospitals of Yunnan Province were retrospectively collected by the Case Report Form (CRF). The age, gender, clinical symptoms at admission; white blood cell (WBC), eosinophil count (EO), red blood cell (RBC), platelet count (PLT), hemoglobin (Hb), hematocrit (HCT), albumin (ALB), alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil), lactate dehydrogenase (LDH), blood urea nitrogen (BUN), serum creatinine (SCr), uric acid (UA) on the first day of admission; and clinical outcomes were recorded. The patients were divided into the non-critical group and the critical group according to the diagnostic criteria, the data of clinical manifestation, laboratory examination, imaging examination and prognosis were compared between the two groups. Multivariate Logistic regression analysis was performed on the variables with statistical significance. The receiver operating characteristic (ROC) curve of LDH and UA for differential diagnosis of severe tsutsugamushi disease were drawn. Results From January 1st, 2017 to December 31st, 2018, 408 patients with tsutsugamushi disease were enrolled in 37 hospitals in 15 prefectures and municipalities of Yunnan Province. 385 cases were clinically diagnosed and 23 cases were laboratory diagnosed. There were 265 cases in non-critical group and 143 cases in critical group. A total of 8 cases died and the remaining 400 cases were discharged from hospital. ① Compared with the non-critical group, age of the critical group was older, the incidence of dizziness, cough, expectoration, general soreness, dyspnea, palpitation, abdominal pain, diarrhea, bulbar conjunctival congestion, pleural effusion, peritoneal effusion, pericardial effusion, hepatomegaly, splenomegaly, and the levels of WBC, ALT, AST, LDH, TBil, BUN, SCr, UA were significantly increased, the incidence of lymph node enlargement and the levels of EO, PLT and ALB were significantly decreased, and there was no significant difference in other indicators between the two groups.② Multivariate Logistic regression analysis showed that age, dyspnea, palpitations, LDH, UA, ALB were risk factors for severe tsutsugamushi disease, βvalue was 0.040,-2.147,-1.414, 0.002, 0.005 and-0.132 respectively, and the odds ratio (OR) was 1.041, 0.117, 0.243, 1.002, 1.005 and 0.877 respectively (all P < 0.01). ③ROC curve analysis showed that UA and LDH had better accuracy in differential diagnosis of severe tsutsugamushi disease (both P < 0.01), and the area under ROC curve (AUC) was 0.693 [95% confidence interval (95%CI) = 0.633-0.754], 0.819 (95%CI = 0.776-0.862), respectively. When the cut-off of UA was 306.2 μmol/L, the sensitivity was 60.8%, and the specificity was 77.4%. When the cut-off of LDH was 485.5 U/L, the sensitivity was 74.8%, and the specificity was 74.7%. The diagnostic value of UA combined with LDH was higher, AUC was 0.832, the sensitivity was 69.9%, and the specificity was 85.3%. Conclusion Severe tsutsugamushi disease can be diagnosed at an early stage according to age, respiratory distress, palpitations, hypoalbuminemia, UA >306.2 μmol/L, and LDH > 485.5 U/L.

Objective:To analyze the clinical features of adult patients with extremely elevated erythrocyte sedimentation rate (ESR, ESR≥100 mm/1 h), so as improve the ability of clinicians to use erythrocyte sedimentation rate to assist in the diagnosis and treatment of diseases.Methods:A retrospective cohort study was conducted to examine the clinical data of patients with ESR ≥ 100 mm/1 h admitted to the First Affiliated Hospital of Kunming Medical University from January 1st 2019 to December 31st 2019. The age, gender, clinical diagnosis, first ESR level after admission, blood routine, liver function, renal function, coagulation function and C-reactive protein (CRP) within 24 hours after admission were collected. Patient cohorts were divided into youth group (18-65 years old), middle-aged group (66-79 years old) and elderly group (≥80 years old) according to the new standards of human age classification of World Health Organization (WHO) 2019. Patient cohorts were also divided into infectious disease group, hematological disease group, autoimmune disease group, renal failure group and others according to their respective clinical diagnosis. The distribution of extremely elevated ESR in each group, and the correlation between ESR and various laboratory indicators were analyzed.Results:① Among 429 patients with ESR≥ 100 mm/1 h, there were 236 males and 193 females. There was no significant difference in ESR levels between males and females [mm/1 h: 108.00 (103.00, 119.75) vs. 117.00 (105.50, 140.00), P = 0.234]. ② The age of 429 patients ranged from 18 to 98 years old, the average age was (53.70±18.70) years old. There were 310 cases in the youth group, 87 cases in the middle-aged group and 32 cases in the elderly group. The ESR level of the young group was significantly lower than that of the middle-aged group and the elderly group [mm/1 h: 108.00 (103.00, 120.00) vs. 119.00 (107.00, 140.00), 120.00 (110.25, 140.00), both P < 0.01]. ③ The main diagnoses associated with extremely elevated ESR were infectious diseases [157 cases (36.6%)], hematological system diseases [127 cases (29.6%)], autoimmune diseases [74 cases (17.2%)]. Pulmonary infection accounted for 58.0% (91/157) of infectious diseases. Hematopoietic stem cell diseases accounted for 45.7% (58/127), lymphocyte and plasma cell diseases accounted for [37.0% (47/127)] and erythrocyte diseases accounted for [11.0% (14/127)] of the hematological system diseases. Diffuse connective tissue diseases accounted for 75.7% (56/74) of autoimmune diseases. ④ Spearman correlation analysis showed that the extremely elevated ESR in all patients was significantly negatively correlated with the levels of red blood cell count (RBC), hemoglobin (HB) and hematocrit (HCT) (ρvalue was -0.395, -0.381 and -0.383, respectively, all P < 0.01), the ESR was significantly positively correlated with the level of fibrinogen (FIB; ρ= 0.345, P < 0.01). A total of 266 patients were tested for both ESR and CRP, and there was no significantly correlation between ESR and CRP level (ρ= -0.019, P = 0.756). Conclusions:The extremely elevated ESR was more common in pulmonary infections diseases, hematopoietic stem cell diseases, lymphocyte and plasma cell diseases, erythrocyte diseases and diffuse connective tissue diseases. The extremely elevated ESR was significantly correlated with the levels of RBC, HB, HCT and FIB.

Objective:To explore the best treatment for local ablation of colon cancer liver metastases (CRLM) by meta-analysis.Methods:The electronic databases of PubMed, Web of Science, Embase, CNKI and the Cochrane Library were searched from the establishment to August 22, 2022, and studies that report outcomes with comparison between microwave ablation (WMA) and radiofrequency ablation (RFA) in CRLM treatment were selected by inclusion and exclusion criteria. Furthermore, the perioperative and survival data were statistically summarized and analyzed by Review Manager 5.3 software.Results:A total of 5 retrospective studies were included with a total sample size of 648 cases, including 316 cases (48.8%) in the WMA group and 332 cases (51.2%) in the RFA group. The results of meta-analysis showed that locoregional recurrence rate in WMA group was significantly lower than that in RFA group. The 1-year and 2-year disease-free survival (DFS) of the WMA group was significantly better than that of the RFA group with HR of 1.77 ( P=0.04, 95% CI: 1.04-3.02) and 1.60 ( P=0.02, 95% CI: 1.09-2.35), respectively. Conclusion:The local control rate and 1-year and 2-year DFS of WMA were superior to RFA.

The clinical data of 4 patients with atypical neurosyphilis (NS) mimicking viral encephalitis (VE) admitted to Beijing Ditan Hospital from July 2015 to January 2020 were retrospectively analyzed. All the 4 patients were males with an average age of (43±8) years. The patients manifested with mental and behavior disorders and cognitive impairment. Three patients had epilepsy and 1 patient had fever. The treponemal pallidum particle agglutination (TPPA) , fluorescent treponemal antibody-absorption test (FTA-ABS) -IgG and toluidine red unheated serum test (TRUST) were all positive in blood and the cerebral spinal fluid (CSF) , and white blood cell count and protein level in CSF were all evaluated. The head MRIs were all abnormal, 3 of which showed hyperintensity in fluid attenuated inversion recovery (FLAIR) and T2-weighted image located in limbic system and 1 showed hyperintensity in the bilateral cortex and the subcortical areas. All patients improved evidently and the lesions became smaller after penicillin treatment. Atypical NS mimicking VE is rare, and at early diagnosis and timely treatments can contribute to a good clinical prognosis.
