Objective To explore the drug selection, usage, dosage and effect of clinical pharmacists in the treatment of secondary Candida bloodstream infection in patients with digestive tract perforation, and provide reference for rational clinical use of such anti-infection therapy. Methods During the treatment of Candida infection, anti-infection specialist clinical pharmacists suggested replacing fluconazole for anti-infection treatment, and adjusted the usage and dosage of caspofungin to ensure the application of full treatment course. Results The patient’s Candida bloodstream infection was effectively controlled. Conclusion Echininocandins such as caspofungin are the first choice for Candida infection. The maintenance dose should be reduced to 35 mg qd in patient with moderate liver function injury, and the anti-infection treatment should be done at least 14 days after the blood culture being negative. Clinical pharmacists participate in clinical pharmaceutical care practices such as clinical ward rounds, and actively assist doctors to develop individualized anti-infection programs, which could improve the level of clinical drug use and the clinical outcome of diseases.

Objective To analyze the clinical characteristics of thyroid dysfunction induced by camrelizumab in the treatment of classical Hodgkin lymphoma(cHL)and explore the influencing factors.Methods The medical records of cHL patients treated with camrelizumab from January 1st,2017 to December 31st,2020,were collected.The clinical characteristics of thyroid dysfunction induced by camrelizumab were analyzed,and the influencing factors of adverse drug reactions(ADRs)were discussed.Results A total of 47 patients were included,12 patients(25.53%)experiencing thyroid dysfunction after receiv-ing camrelizumab.Among them,3 patients had hypothyroidism,7 had subclinical hypothyroidism,and 2 had subclinical hyperthy-roidism.The severity of ADRs was between grade 1 and 2(mild to moderate).None of the patients with thyroid dysfunction dis-continued camrelizumab.Thyroid dysfunction occurred between 1 and 22 months after camrelizumab treatment,with a median time of 6 months.2 patients with hypothyroidism treated with levothyroxine,the thyroid function returned to normal in 1 patient and was improved in the other.1 patient with subclinical hypothyroidism was treated with levothyroxine with the thyroid function continued to be abnormal.The rest of the 9 patients with thyroid dysfunction received no intervention,and 4 of them returned to normal,and others remained with no obvious change or loss in follow-up.Thyroid dysfunction was associated with baseline thyroid stimulating hormone level(P=0.03).The level of thyroglobulin antibodies and thyroid peroxidase antibodies was increased in 2 patients a-mong 3 patients with moderate thyroid dysfunction.Conclusion The incidence of thyroid dysfunction induced by camrelizum-ab in cHL was high.Camrelizumab-induced thyroid dysfunction was related to TSH baseline level(P=0.03).The severity was between grade 1 and 2,which was related to the level of TgAb and TPOAb.The subtype of thyroid dysfunction was mainly sub-clinical hypothyroidism with a long period.Patients could continue camrelizumab treatment,and the thyroid function of patients with grade 2 hypothyroidism was improved after the treatment with levothyroxine.

Objective:To study the influence of the severity of diabetic retinopathy (DR) on the visual function of patients with type 2 diabetes, to provide scientific basis for the early prevention and control of DR.Methods:This study was designed as a cross-sectional study, recruiting already-diagnosed type 2 diabetes patients in four community health service centers in Guizhou Province between February and September 2022. Employing the Chinese version of the Visual Function Index-14 (VF-14), assess the participants′ near vision, visual adaptation, subjective visual perception, and stereo vision, with higher scores indicating poorer visual function. Categorize the severity of each eye′s damage into no diabetic retinopathy (DR), mild non-proliferative diabetic retinopathy (NPDR), moderate NPDR, severe NPDR, and proliferative diabetic retinopathy (PDR), and use a 5-level DR grading system to evaluate the overall severity of diabetic retinopathy in both eyes. Employing linear regression analysis to investigate the linear relationship between DR and visual function index. Local weighted regression evaluates the nonlinear relationship between the DR composite score and the scores of visual function, with a steeper slope indicating poorer visual function for that level.Results:A total of 542 patients with type 2 diabetes were investigated, including 244 (45.02%) males, 298 (54.98%) females, and 162 (29.89%) patients with DR. After adjusting for confounders, compared with those without DR, patients with binocular DR Had overall scores ( β=0.136, P=0.003), near vision ( β=0.163, P<0.001), visual adaptation ( β=0.092, P=0.042), subjective vision ( β=0.120, P=0.009) and stereo vision ( β=0.094, P=0.044) were higher than those without DR. There were no differences in visual functions between DR And monocular DR. The local weighted regression curve showed that near vision (slope: 23.78) and overall score (slope: 58.37) increased sharply from mild to moderate NPDR in both eyes. Visual adaptation (slope: 5.37, 7.72), subjective vision (slope: 6.53, 7.93), stereovision (slope: 0.74, 0.91) increased slowly in mild to moderate NPDR in both eyes and in moderate to severe NPDR/PDR in both eyes. Conclusion:Binocular DR is associated with impaired visual function, but there is no difference between monocular DR And non-DR visual function. The early damage of DR To visual function is mainly manifested in near vision. In the prevention and control of DR, more attention should be paid to visual function, especially the change of near vision, and retinal damage should not be assessed solely by visual status.

ObjectiveTo explore the relationship between schizotypal personality traits and creativity in college students and the mediating role of cognitive flexibility. MethodsSchizotypal Personality Questionnaire （SPQ）， Cognitive Flexibility Inventory （CFI） and Williams Creative Aptitude Test （WCAT） were used to assess 471 college students. Thereafter， Spearman correlation analysis was used to explore the relationship among the variables and the Bootstrap methodology was used to estimate the mediating role of cognitive flexibility. ResultsThe total SPQ， positive and disorganized schizotypal traits scores， and CFI score were all positively correlated with WCAT score （r=0.241~0.313， P<0.01）. The total SPQ， positive and disorganized schizotypal traits scores were also positively correlated with CFI score （r=0.111~0.128， P<0.05）. Cognitive flexibility mediated the relationship between positive schizotypal traits and creativity ［indirect effect=0.052 （95% CI： 0.016~0.112， P<0.01）， accounting for 11.93% of the total effect］. Cognitive flexibility mediated the relationship between disorganized schizotypal traits and creativity ［indirect effect=0.075 （95% CI： 0.020~0.161， P<0.01）， accounting for 11.50% of the total effect］. ConclusionSchizotypal personality has a direct impact on the creativity of medical students and also cause an indirect impact on their creativity through the mediating role of cognitive flexibility.

Objective:To evaluate the accuracy of lung recruitment maneuver (LRM) combined with brachial artery peak velocity variation (ΔVp) in predicting fluid responsiveness.Methods:Sixty-four patients of both sexes, aged 18-64 yr, with body mass index 19-26 kg/m 2, of American Society of Anesthesiologists physical status Ⅰor Ⅱ, with New York Heart Association class Ⅰor Ⅱ, scheduled for elective open gastrointestinal surgery under general anesthesia, were enrolled in this study.LRM (positive airway pressure was maintained at 30 cmH 2O for 10 s) and volume loading test were performed in sequence after anesthesia induction.ΔVp was measured by ultrasonography at the beginning of LRM.Mean arterial pressure (MAP), heart rate (HR), central venous pressure (CVP) and stroke volume (SV) were recorded before LRM (T 1), during LRM (T 2), before volume expansion (T 3) and after volume expansion (T 4). The changing rate of each index before and after LRM (ΔMAP LRM, ΔHR LRM, ΔCVP LRM, ΔSV LRM) and before and after volume expansion (ΔMAP VE, ΔHR VE, ΔCVP VE, ΔSV VE) were calculated.ΔSV VE≥15% was considered to be a positive response after volume expansion, and patients were divided into response group (≥ 15%, R group) and non-response group (< 15%, NR group). Results:There were 34 cases in R group and 30 cases in NR group.Compared with NR group, MAP at T 2 and SV at T 1, 2 were significantly decreased, ΔMAP LRM, ΔMAP VE, ΔSV LRM and ΔSV VE were increased, and ΔVp was increased in group R ( P<0.05). There was a positive correlation between ΔVp and ΔSV VE ( r=0.829, P<0.05), a negative correlation between ΔSV LRM and ΔSV VE ( r=-0.876, P<0.05), and a negative correlation between ΔVp and ΔSV LRM ( r=-0.819, P<0.05). The area under the receiver operating characteristic curve of LRM combined with ΔVp was 0.808, and the cut-off value was 32.3%, the sensitivity 75.3%, and the specificity 88.2%. Conclusion:LRM combined with ΔVp (≥32.3%) can accurately predict the intraoperative fluid responsiveness in patients.

Objective: To explore the association between the efficacy of peg-IFN and the complexity of TP and RT regions of hepatitis B virus (HBV) in chronic hepatitis B. Methods: Patients with HBeAg positive, HBV DNA positive chronic hepatitis B were given peg-interferon 180 μg once a week for subcutaneous injection, and baseline information was collected from baseline and after 12 weeks’ treatment. The baseline HBV DNA TP and RT fragments were amplified, database, high-throughput sequencing, and the average genetic distance calculation. Results: Data of 108 patients were analyzed by logistic regression. RT area fragment Markov distance and TP area fragment Shannon quotient for HBV DNA response were calculated. ALT level is good for HBeAg response. HBsAg level is bad for HBsAg response. Conclusions The complexity of the baseline TP and RT regions may be associated with the efficacy of peg-interferon therapy for CHB.

Objective: To investigate the differences in frequency and function of natural killer cells (NK) between chronic hepatitis B (CHB) and acute hepatitis B (AHB). Methods: Patients with AHB and those with CHB in immune active (IA) phase were enrolled. The frequencies of NK, CD56^dimNK, CD56^brightNK and the expression of functional molecules IFNAR2 and NKp46 on the surface of NK cells were detected respectively among patients with CHB in IA phase, patients with AHB, and those recovered from AHB. At the same time, their correlations with ALT, HBV DNA and HBV markers were analyzed. Results: Between IA and AHB, the frequencies of NK cells and NKp46^dim NK cells in AHB cases were significantly lower than those in IA cases, but the frequency of NKp46^high NK cells in AHB was higher than that in IA. For patients who recovered from AHB, the frequency of NK cells and NKp46^dim NK cells increased; the varied ranges of frequencies of CD56^dimNK, IFNAR2⁺ NK and NKp46⁺ NK cells were on the rise, while the frequency of NKp46^high NK cells decreased after the recovery from AHB, and the varied ranges of CD56^brightNK and IFNAR2MFI, NKp46MFI decreased. In AHB, HBVDNA loads were positively correlated with ALT levels. Before and after the recovery of AHB: ΔHBV DNA and ΔALT, Δ NK/LY (%) were positively correlated; ΔALT and ΔNKp46^highNK/NK(%), ΔNKp46MFI, ΔIFNAR2MFI were positively correlated. Conclusions In CHB immune active phase, the activity of peripheral blood NK cells was too weak to remove the virus, but NK cells play an important role in eliminating the viruses and mediating liver tissue inflammation in AHB.

Objective: To explore the persistent viral response rate (SVR) in patients with refractory chronic hepatitis C after interferon (IFN) (peginterferon 360 μg qw) and ribavirin (PR) therapy failure. The SVR of patients with refractory chronic hepatitis C was improved by PR combined with direct antiviral agents (DAA) and proper extension of the course of therapy was applied. Methods: Seventeen cases of refractory chronic hepatitis C after IFN(peginterferon 360 μg qw) and ribavirin therapy failure were given PR combined with DAA treatment. The side effects were observed and corresponding adjustments were made on drug dosage, and SVR was recorded. Results: The 17 cases completed the whole course of treatment with PR combined with DAA for 24 weeks. All the 17 patients obtained rapid viralogical response (RVR) and SVR. After treatment, the SVR rate was 100% in patients including those with virologic relapse, retreated or previously non-responsive patients with refractory chronic hepatitis C. The adverse reaction of PR combined with DAA 24 weeks was generally mild. Conclusions The use of PR combined with DAA re-treatment in patients with refractory chronic hepatitis C can achieve SVR and shorten the treatment time. PR combined with DAA re-therapy is one of effective treatments to improve the rate of sustained viral response in patients with refractory chronic hepatitis C.

Objective To investigate the effectiveness of predicting the incidence of supine hy-potension syndrome (SHS)after spinal anesthesia measured by ultrasonic measurement of the varia-tion of brachial artery peak velocity in different positions of parturient.Methods Parturient scheduled for elective cesarean section,ASA physical status Ⅰ or Ⅱ,were divided into SHS group and no-SHS group (SBP in the upper extremity decreased by > 30 mm Hg or decreased to < 80 mm Hg)after spinal anesthesia.HR,SBP,DBP of supine position and left lateral position before anesthesia were re-corded,and brachial artery peak velocity were measured by Ultrasonic.The differences of the above indexs before and after the transformation position were calculated.The receiver operating characteris-tic curve (ROC)was plotted by indexs of which P values were less than 0.05,to evaluate the predic-tive effect of each index on SHS after spinal anesthesia.Results Among the 196 patients,89 cases (45.4%)developed SHS after spinal anesthesia.SBP,DBP,peak velocity of brachial artery (Vpmin) and brachial artery peak velocity variation (ΔVp)were different before and after the transformation position (P<0.05).The difference in SHS group was significantly higher than no-SHS group.The areas under ROC curve (AUC)of ΔSBP,ΔDBP,ΔVpmin,ΔΔVp were 0.711 (95%CI 0.575-0.846), 0.573 (95%CI 0.419-0.727),0.948 (95% CI 0.895-0.987),0.864 (95% CI 0.770-0.958),and the cut-off values were 17.5 mm Hg,7.6 mm Hg,17.8 cm/s,and 13.1%.Conclusion The differ-ence of brachial artery peak velocity measured by ultrasonic in different positions of parturient can ef-fectively predict the occurrence of SHS,in which ΔVpmin≥ 17.8 cm/s has better predictive effect.
