AIM: To explore the efficacy of 0.05% cyclosporine A combined with olopatadine eye drops in treating allergic conjunctivitis-related dry eye disease.METHODS: A total of 63 patients(63 eyes)with allergic conjunctivitis-related dry eye disease in the People's Hospital of Guangxi Zhuang Autonomous Region from August 2022 to April 2023 were enrolled and randomly divided into control group(n=33)and observation group(n=30). The patients of the control group were administrated with 0.1% olopatadine eye drops and 0.3% sodium hyaluronate eye drops, while the observation group was administrated with 0.1% olopatadine eye drops and 0.05% cyclosporine A eye drops. The ocular surface disease index(OSDI), total ocular symptom score(TOSS), conjunctival congestion score, conjunctival papillae and follicle score, Schirmer I test(SⅠt), tear meniscus height(TMH), meibomian gland secretion ability and property score, meibomian gland loss area score, corneal fluorescein staining(CFS), tear film break-up time(BUT), noninvasive first tear film break-up time(NIBUTf), noninvasive average tear film break-up time(NIBUTav)before and after treatment and the drug safety during the treatment period of both groups of patients were evaluated.RESULTS: After treatment, OSDI, TOSS, conjunctival congestion score, conjunctival papillae and follicle score, SⅠt, TMH, meibomian gland secretion ability score and property score, CFS, BUT, NIBUTf, and NIBUTav of the observation group showed improvements compared with those before treatment(all P<0.017). Among these, OSDI, TOSS, conjunctival congestion score, conjunctival papillae and follicle score, BUT, NIBUTf, and NIBUTav demonstrated significant improvement compared with the control group(all P<0.05). There was no statistically significant difference in meibomian gland loss area score between the two groups before and after treatment(P>0.05). During the treatment period, there were no local or systemic adverse reactions.CONCLUSION: The combined use of 0.05% cyclosporine A and olopatadine eye drops can significantly improve ocular discomfort symptoms of patients with dry eye disease associated with allergic conjunctivitis, such as red eyes, itchy eyes and foreign body sensation, promote tear film stability and have high safety.

BACKGROUND:Increased homocysteine level induces apoptosis of human umbilical vein endothelial cells,but the mechanism remains unclear. OBJECTIVE:To investigate the role of hsa-circ-0001360 in human umbilical vein endothelial cell apoptosis induced by homocysteine. METHODS:In vitro cultured human umbilical vein endothelial cells were divided into control group,homocysteine group,interference control group,interference control + homocysteine group,hsa-circ-0001360 interference group,hsa-circ-0001360 + homocysteine interference group,overexpression control group,overexpression control + homocysteine group,hsa-circ-0001360 overexpression group and hsa-circ-0001360 + homocysteine overexpression group.All groups were treated with 100 μmol/L homocysteine.After 72 hours of intervention,the expressions of apoptosis-related proteins Bax,Bcl-2,and Caspase-3 were detected by western blot assay.The apoptotic rate was detected by flow cytometry.Quantitative real-time PCR was used to detect the expression of hsa-circ-0001360.

Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

Objective:To investigate clinicians' compliance with the 2018 Surviving Sepsis Campaign (SSC) update "1-hour sepsis Bundle therapy" (1-hour Bundle) when treating patients with Sepsis 3 in the intensive care unit (ICU), and to analyze its impact on patient outcomes.Methods:A multicenter, prospective observational cohort study was conducted. A total of 153 ICU patients in Ziyang First People's Hospital, Ziyang People's Hospital and Yanjiang District People's Hospital who were diagnosed of sepsis by the definition and diagnostic criteria of Sepsis 3 from January 2019 to December 2020 were selected. Among them, 95 patients who had completed 1-hour Bundle were divided into the Bundle compliance group. 58 patients who did not complete the Bundle within 1 hours were classified as the Bundle non-compliance group. The distribution of pathogenic bacteria and infected sites, 1-hour Bundle compliance and 28-day survival in the 3 hospitals were analyzed. Univariate analysis was used to analyze the risk factors affecting the prognostic between the two groups of sepsis patients. Cox regression model was used to draw a 28-day survival curve to evaluate the survival of the patients in the two groups.Results:Among 153 sepsis patients in 3 hospitals, the detection rate of pathogenic bacteria was 61.44% (94/153), and Gram-negative bacteria accounted for 79.79% (75/94). The top 3 infection sites were respiratory system, gastrointestinal tract and urinary system, accounted for 32.0%, 28.1% and 18.3%, respectively. In the 3 hospitals, 62.09% (95/153) of patients fully implemented the 1-hour Bundle. The poorly implemented indicators in the 1-hour Bundle were 1-hour blood microbial culture [77.78% (119/153)] and 1-hour antimicrobial application [79.74% (122/153)]. There was no significant difference in the baseline indicators between Bundle compliance and non-compliance groups. Univariate analysis showed that the main prognostic indicators: 28-day survival rate in the Bundle compliance group was significantly higher than that in the Bundle non-compliance group [80.00% (76/95) vs. 62.06% (36/58), χ2= 6.447, P = 0.014]. Secondary evaluation indicators: mean arterial pressure (MAP) at 6 hours and 24 hours in the Bundle compliance group were significantly higher than those in the Bundle non-compliance group [mmHg (1 mmHg = 0.133 kPa): 78.22±11.25 vs. 69.86±14.04, 79.78±11.45 vs. 75.35±12.90]. However, the median length of in hospital stay in the Bundle compliance group was significantly longer than that in the Bundle non-compliance group [days: 13 (17) vs. 6 (11)], with statistically significant differences (all P < 0.05). Bivariate Logistic regression analysis showed that 6 hours and 24 hours MAP were risk factors affecting the prognosis of patients with sepsis [odds ratio ( OR), 95% confidence interval (95% CI): 1.064 (0.994-1.102), 1.032 (1.003-1.063), both P < 0.05]. Conclusions:The 1-hour Bundle compliance rate of ICU patients with sepsis in 3 hospitals of Ziyang City was 62.09%, and the compliance is still to be improved, especially for the 2 aspects of empirical antimicrobial use and microbial culture retention before antimicrobial use. The 28-day survival rate in the Bundle compliance group was significantly higher than that in the Bundle non-compliance group, suggesting that the 1-hour Bundle regimen can improve the prognosis of patients with sepsis.

Objective To investigate the diagnosis and therapy by improving the further understanding of adrenal hemorrhage.Methods The clinical data of 12 cases of adrenal hemorrhage confirmed by pathology admitted to the First Hospital of China Medical University from October 2006 to October 2017 were retrospectively analyzed.Observe the patient's clinical manifestations,imaging features,treatment methods and prognosis.Results All 12 cases were unilateral adrenal hemorrhage,8 cases manifested lumbago in troubled side,2 cases manifested abdominal pain,and 2 cases were found during physical examination incidentally with no obvious symptoms.Ultrasound-B was performed in 10 cases,revealed low echo of masses in 5 cases,mixed echo of masses in 2 cases,cystic echo of masses in 2 cases,and no abnormality in 1 case.All 12 cases were scanned by CT,9 cases showed cystic masses with mixed density,and 3 cases showed solid masses.The value of plain CT ranged from 31 HU to 77 HU,no obvious enhancement was found in enhanced scan.One case was scanned by MRI,showed round mass in left adrenal gland,with uneven signal.The main signal was iso-signal in T1-weighted and T2-weighted.Six cases underwent adrenal and mass resection through the 11th rib,3 cases underwent retroperitoneoscopic adrenalectomy,2 cases underwent abdominal exploration and accepted adrenalectomy and hematoma removal,and 1 case was discharged after conservative treatment because of surgery contraindication.11 cases of the pathology of postoperation were adrenal hemorrhage.Conclusions Preoperative diagnosis of adrenal hemorrhage is relatively difficult,ultrasound-B,CT,and MRI examination can help diagnose.Surgical treatment should be performed for patients who can tolerate surgery and with larger hematoma (＞5 cm).

Objcetive: To explore the treatment of long segment defect of tibia by using tensor fascia lata combined with iliac flap or deep circumflex iliac pedicle iliac flap. Methods: From February 2012 to August 2017, The People′s Hospital of Zun Yi City Bo Zhou District treated 16 patients who had long segment defect of tibia.There were 11 males and 5 females, age from 22 to 58 years old, the average age was 42 years old. Iliac flap grafting with tensor fascia lata combined with iliac flap or deep circumflex iliac pedicle was used to treat the defect of long segment of tibia. There were 4 cases with simple tibial defect and 12 cases with skin defect. The longest tibial defect was 5-8 cm. Results: In this study, four patients used iliac flaps with deep circumflex iliac pedicle, the area of flaps ranged from 2.5 cm×5.0 cm to 5.0 cm×10.0 cm, while the area of iliac flaps ranged from 5.0 cm×2.5 cm to 8.0 cm×4.0 cm. Twelve patients used grafting with tensor fascia lata combined with iliac flap, the area of flaps ranged from 5.0 cm×12.0 cm to 12.0 cm×23.0 cm, while the area of iliac flaps ranged from 7.0 cm×2.0 cm to 8.0 cm×4.0 cm. All 16 cases of bone flap were survived, fracture healing, without surgical complications. The average follow-up period was 1.5 years, the flaps had good appearance in 10 cases and was slightly bloated in 6 cases; the ankle had normal motion in 14 cases and had poor dorsal extension in 2 cases. X-ray films showed that the bone flap repaired the bone defects and reached bone healing. Conclusions Vascularized tensor fascia lata combined with iliac flap or deep circumflex iliac pedicle iliac flap grafts increase local blood supply and accelerate the process of fracture healing.

Results On the basis of rehydration and anti -infective therapy , 9 patients underwent continuous bed peritoneal dialysis(CAPD) treatment.The average duration of peritoneal dialysis was 11 days.The average hospital stay was 33 days.The levels of blood urea nitrogen and creatinine were (17.69 ±6.01)mmol/L,(412.21 ±188.74)μmol/L at 5 days after peritoneal dialysis,and the levels of blood urea nitrogen and creatinine were (35.24 ±8.35)mmol/L, (801.23 ±298.15)μmol/L before the peritoneal dialysis,the differences were statistically significant (t =5.12, 3.31,all P<0.01).The levels of blood urea nitrogen and creatinine were (9.76 ±3.37) mmol/L,(168.48 ± 112.25)μmol/L at 10 days after peritoneal dialysis,there were significant improvements compared with 5 days after peritoneal dialysis(t=3.45,3.33,all P<0.01).The symptoms of uremia disappeared or improved obviously ,and the complications of peritoneal dialysis were not obvious .Conclusion Pediatric burns with acute renal failure with dialysis indications preferred peritoneal dialysis treatment ,in the course of treatment should take into account the ade-quacy of dialysis and children with the development of individualized programs .

Objective To investigate the correlation between serum vitamin D level in human body and Chlamydia trachomatis (Ct) genitourinary tract infection. Methods This study enrolled 174 outpa-tients (male: 95, female: 79, 20-49 years) infected with Ct and 380 healthy subjects (male: 211, female:169, 20-49 years) in Tianjin from November 1, 2016 to March 15, 2017. Blood samples were collected from all subjects after fasting overnight and the time points for sample collection in the Ct infection group were before and after a course of antibiotic treatment. Serum 25-hydroxyvitamin D [25-(OH)D] levels were measured with enzyme-linked immunosorbent assay (ELISA). PCR assay was used to assess the recovery in those patients one month after a course of treatment. Two case-control studies were respectively conducted, in which 161 patients and 161 healthy subjects as well as 41 uncured patients and 41 cured patients were randomly selected and matched for gender and age. Statistical analysis was performed using SPSS19. 0. Re-sults The two case-control studies showed that vitamin D deficiency was a risk factor for both Ct genital tract infection and poor efficacy, of which the adjusted ORs were 2. 281 (95％ CI: 1. 438, 3. 619) and 7. 266 (95％ CI: 2. 551, 21. 036). Among all subjects aged 20-39, male patients had lower 25-(OH)D level in serum than healthy men [(40. 10±17. 93) nmol/ L vs (53. 72±18. 00) nmol/ L, P< 0. 01] and fe-male patients also had lower 25-(OH)D level in serum than healthy women [(35. 71±19. 99) nmol/ L vs (45. 42±16. 08) nmol/ L, P<0. 01]. The levels of 25-(OH)D in uncured male and female patients were re-spectively lower than those in cured male and female patients [(30. 50±14. 53) nmol/ L vs (41. 32±17. 24) nmol/ L; (29. 47±16. 66) nmol/ L vs (41. 37±21. 03) nmol/ L; both P<0. 05]. Conclusion Vitamin D deficiency related to Ct infection in human genitourinary tract and poor prognosis. Lower serum vitamin D levels might increase the risk of Ct genitourinary tract infection and reduce the efficacy of treatment.

Objective To investigate the sequence variations of mitochondrial D-loop region in chronic glomerular nephritis patients and family members and their possible associations with chronic glomerular nephritis.Methods 20 patients with chronic glomerular nephritis and 48 unaffected pedigree members,as well as 122 cases of normal control were recruited.mtDNA extracted from peripheral blood were examined by PCR-based assay for D-loop sequence variations,followed by sequencing analysis.Results Compared with the normal control and standard sequence,a total of 61 sequence variants were detected,among these,three high variations were found,and the base variation rate of patients with chronic glomerular nephritis(CGN)and unaffected pedigree members(UAPM)(0.88%,0.72%)significantly increased compared with the control group(0.61%).The distibutional difference of base variation rate in the experimental groups were significantly higher than those in the control group(x2=21.220,7.964,all P<0.05).Especially in microsatellite variation in D310 region,the mutation frequency and base variation rate in patients with CGN were 100.00% and 30.00%,respectively,which of UAPM were 81.30% and 17.95%,respectively,while those in the normal control group were 53.30% and 6.05%,respectively.Among them,the patients with CGN compared with the control group had statistically significant differences(x2=15.610,150.047,all P<0.05).Likewise,UAPM also had statistically significant difference compared with the control group(x2=11.347,66.188,all P<0.05).Conclusion D-Loop of mitochondrial genome mutations may be related to the development of chronic glomerular nephritis.

OBJECTIVETo investigate the relationship between fetal lateral ventriculomegaly and chromosomal microarray analysis (CMA) abnormalities.

METHODSFifty fetuses with lateral ventriculomegaly detected by ultrasound and a normal karyotype were included. Forty four fetuses were classified as mild ventriculomegaly (MVM), in which the lateral ventricular atrium was 10-15 mm. Six had severe ventriculomegaly (SVM), with the lateral ventricularatrium being ≥ 15 mm. The fetuses were also divided into isolated (n= 21) and non-isolated groups (n= 29) based on whether they are associated with other anomalies.

RESULTSThirteen (26%) of the fetuses were found to be abnormal by CMA. For the 44 cases with MVM, 9 (20.9% ) were found to be abnormal, while for the 6 cases with SMV, 4 (66.7%) were found to be abnormal (P>0.05). CMA abnormalities were found in 2 (9.5%) of the 21 fetuses with isolated ventriculomegaly group and 11 (37.9%) of the 29 fetuses with non-isolated ventriculomegaly group (P<0.05).

CONCLUSIONChromosome microdeletions and microduplications are the most common abnormalities found in fetal lateral ventriculomegaly. When ventriculomegaly is associated with other anomalies, the incidence of CMA abnormally is much higher. Prenatal diagnosis is necessary for fetuses with lateral ventriculomegaly.
