RESUMEN
Objective To investigate the influencing factors of vancomycin in the area under curve for 24 h(AUC0-24h)in patients after orthopedic surgery,and to predictive and analyze a good pharmacokinetic model for AUC0-24h Methods Patients who underwent orthopedic surgery and used vancomycin in The Sixth Affiliated Hospital of Xinjiang Medical University from January 2018 to December 2022 were included,and the basic information,the medication,the blood and biochemical indexes of the patients were collected to analyze the factors affecting postoperative vancomycin AUC0-24h in orthopedic surgery.The AUC0-24h was calculated using the first-level pharmacokinetic formula,the JavaPK? for Desktop(JPKD)and the vancomycin daily dose elimination rate formula.Results 91 patients were finally included,and the cystatin C(OR=189.168,P=0.005)and the single dose(OR=19.160,P<0.001)were independent protective factors for vancomycin AUC0 24 h in postoperative orthopedic patients,and the retinol binding protein was an independent risk factor for vancomycin AUC0-24h(OR=0.910,P<0.05).By predicting and analyzing the model of vancomycin AUC0 24h in postoperative orthopedic patients,the absolute percentage error of both JPKD software and vancomycin daily dose elimination rate formula were lower than 30%.The intraclass correlation efficient between the AUC0 24h of the JPKD software and vancomycin daily dose elimination rate formula,and the AUC0 24h of the first-level pharmacokinetic formula were 0.781 and 0.524,respectively.Conclusion Cystatin C is an important factor influencing vancomycin AUC0-24h in postoperative orthopedic patients,and JPKD software is more suitable for predicting vancomycin AUC0-24h after orthopedic surgery than the vancomycin daily dose elimination rate formula method.
RESUMEN
Objective:To discuss the clinical results of treatment for congenital muscular torticollis with different injection points of botulinum toxin type A and traditional conservative method, and to expound the safety and effectiveness of this way.Methods:From January 2018 to December 2018, 60 cases aged from one month to six months with congenital muscular torticollis who visited the outpatient clinic of plastic surgery in Children's Hospital of Quanzhou, a teaching hospital of FuJian Medical University, and there were 38 males and 22 females. The treatment groups were divided into two groups according to random number method that were treated with botulinum toxin type A: the single point group was given one point injection, and the three-point group was injected with three points, while the control group was treated with traditional conservative treatment (mainly manual stretching exercises). The number of cases in each group was 20.Results:The differences of muscle thickness and muscle length were repeatedly measured at different time points in the same group and variance analysis conducted. The results showed that there were statistical significances among the two indicators at different time points in each group ( P<0.05). Least significant difference (LSD) was further adopted for pairwise comparison between indicators at different time points in each group and the differences were statistically significant ( P<0.05). In the comparison of treatment effect of different groups after twelve months follow-up, the cure rate was 85% (17 cases) in the single point group, 95 % (19 cases) in the three-point group, and 80 % (16 cases) in the control group, there was no significant difference among three groups ( P>0.05). Conclusions:Local injection of botulinum toxin type A is a safe and effective treatment option for congenital muscular torticollis, which can achieve the same clinical effect as traditional conservative treatment.
RESUMEN
Objective:To explore the value of 99Tcm-MIBI SPECT/CT in diagnosis of color Doppler ultrasound (CDUS) uncertain cervical lymph node metastasis after surgical resection of papillary thyroid carcinoma (PTC). Methods: A total of 31 patients with CDUS uncertain cervical lymph node metastasis after surgical resection of PTC were collected. 99Tcm-MIBI SPECT/CT of the neck was performed one month within operation, then 99Tcm-MIBI SPECT/CT, 131I SPECT/CT of the neck were performed within 15 days. The diagnostic efficiency of 99Tcm-MIBI SPECT/CT was observed. Results: Among 31 PTC patients, cervical lymph node metastases were detected in 6 (6/31, 19.35%) patients. The sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) of 99Tcm-MIBI SPECT/CT was 66.67% (4/6), 96.00% (24/25), 90.32% (28/31), 80.00% (4/5) and 92.31% (24/26), respectively. Totally 14 cervical metastatic lesions were found, the sensitivity and PPV of 99Tcm-MIBI SPECT/CT in diagnosis of cervical metastatic lesions was 71.43% (10/14) and 83.33% (10/12), of 131I SPECT/CT was 28.57% (4/14) and 100% (4/4), respectively. 99Tcm-MIBI SPECT/CT showed higher sensitivity than 131I SPECT/CT (χ2=5.14, P0.05). Conclusion: 99Tcm-MIBI SPECT/CT could be used to correctly localize most cervical lymph node metastasis of PTC, providing further information for judging 131I SPECT/CT and CDUS uncertain cervical lymph node metastases in postoperative PTC patients.
RESUMEN
OBJECTIVE: To observe the improvement effects of ethanol extract of the root of Anacyclus pyrethrum (EEAP) on cough variant asthma (CVA) model rats. METHODS: Male SD rats were randomly divided into control group, model group, prednisone acetate group (positive control, 250 mg/kg), EEAP low-dose, medium-dose and high-dose groups (160, 320, 640 mg/kg, by the weight of EEAP), with 10 rats in each group. Except for control group, other group was given 1 mg/mL ovalbumin (OVA)-Freunds adjuvant complete solution subcutaneously, and aerosol inhalation of 1% OVA-normal saline (once a day, 20 min each time, 15 d) to induce CVA. After last inhalation, control group and model group were given constant volume of water intragastrically; administration groups were given relevant medicine intragastrically, once a day, for consecutive 30 d. General symptoms of rats were observed in each group during experiment. The airway sensitivity of rats in each group was investigated by capsaicin cough provocation test, and the cough times were recorded. The contents of SOD and TNF-α in serum were determined by ELISA. The morphological characteristics of lung tissue were observed by HE staining. The number of eosinophils and leucocytes in alveolar lavage fluid was recorded by Rayleigh staining. RESULTS: Rats in the control group breathed smoothly, responded quickly and had glossy coat. The rest of the groups showed restlessness, cough, shortness of breath and other symptoms after antigen stimulation. Compared with control group, the congestion and edema of bronchial wall and infiltration of inflammatory cells in the lung tissue were observed in model group; the cough times increased significantly; serum content of TNF-α, eosinophil and leukocyte counts in alveolar lavage fluid increased significantly, and serum content of SOD decreased significantly (P<0.05). After treatment, above symptoms of rats were alleviated to varying degrees in administration groups, and the cough times were significantly reduced; the serum contents of TNF-α as well as eosinophil and leukocyte counts in alveolar lavage fluid were significantly reduced; the serum contents of SOD was increased significantly, but the cough times of EEAP groups were significantly higher than that of prednisone acetate group (P<0.05). CONCLUSIONS: EEAP may show the anti-inflammatory and antiasthmatic effects by inhibiting the secretion of TNF-α, increasing the content of SOD and inhibiting inflammatory cell infiltration.

RESUMEN
Objective To investigate the possibility that procalcitonin (PCT) can predict the outcome of ventilator weaning in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD). Methods The AECOPD patients caused by bacteria who received mechanical ventilation in intensive care unit (ICU)of the General Hospital of China National Petroleum Corporation in Jilin from January 2010 to March 2014 were retrospectively selected,and their venous blood PCT levels were monitored daily. When they had passed the spontaneous breathing trial(SBT),their breathing machine and trachea cannula were removed. Afterwards they were closely observed for 48 hours and divided into two groups:success and failure groups according to the outcome of the first weaning,and then the analysis of the PCT difference between the two groups was made. Results In the 52 patients enrolled,there were 38 patients in the success group and 14 patients in the failure group. The baseline information as age,sex,acute physiology and chronic health evaluationⅡ(APACHEⅡ)score between the two groups showed no significant difference(all P>0.05). There was no statistical significant difference in PCT level(μg/L) between success and failure groups when they were admitted(5.33±1.35 and 5.37±1.34,respectively). When they were weaning,the PCT levels of both groups had reduced to some extent(1.37±0.39 and 1.74±0.42,respectively), and the success group was lower than that in the failure group(t=2.971,P=0.005). Conclusion PCT level can be used as a predictive index to guide the time for ventilator weaning in patients with AECOPD.

RESUMEN
Objective To explore the association of serum bilirubin level at the time of admission with the compos?ite outcome(disability or death)in discharged patients with acute ischemic stroke. Methods In a retrospective cohortstudy from June 1st 2009 to May 31st 2012, we continuously included 3151 patients with acute ischemic stroke and col?lected demography,lifestyle,clinical manifestations and laboratory test data. Functional outcome was measured with themodified Rankin scale (mRS) when subjects were discharged. Disability was defined as mRS≥3 and composite outcomewas defined as mRS≥3 or death. Serum bilirubin was divided into four groups according to the quartile. Multiple Coxregression analysis was used to assess the independent relation between serum bilirubin and disability death and the com?posite outcome. Results There were 407 disabled patients,the disability rate was 12.9%;and 104 patients were dead,the fatality rate was 3.3%.After adjusting for multiple factors, we found the risks of composite outcome with total bilirubin in the four quartile were higher than that in the first quartile, aHR and 95%CI were 1.335(1.047~1.702) respectively;The risks of composite outcome with indirect bilirubin in the four quartile were higher than that in the first quartile, aHR and 95%CI were 1.355(1.062~1.728) respectively; The risks of composite outcome with bilirubin direct in the third and the forth quartile were higher than that in the first quartile, aHR and 95% CI were11.403(1.089~1.807)and 1.431 (1.118~1.833) respectively.With the increase of total bilirubin,indirect bilirubin and direct bilirubin level,the compos?ite outcome of discharged patient was on the increase. Conclusions The study indicated that higher serum bilirubincould increase the risk of composite outcome in ischemic stroke patients, there was dose-response relationship ,and bili?rubin was a independent risk factor.

Objective To investigate the relationship between molecular biological markers and recombinant human endostatin targeted therapy in non-small-cell lung cancer(NSCLC).Methods 68 cases patients with non-small-cell lung cancer to meet the requirements were randomly divided into group A (n=34)and group B (n=34).Group A received docetaxel and cisplatin(DP)and gefitinib;group B received recombinant human endostatin on the base of group A.The biological markers species,such as,EGFR,KRAS,VEGF,BRCA1,EML4-ALK,ERCC1,β-tubulin and CD3 were detected by immunohistochemical.The types of population for different programs were summarized according to the expression of biological markers and progression free survival (PFS)of the two groups. Results Group B median PFS was significantly longer than that in group A;no matter low or high expression of VEGF and BRCA1,group B median PFS was significantly longer than that in group A(P<0.05);high expression of ERCC1,KRAS,EML4-ALK andβ-tubulin,group B median PFS was significantly longer than that in group A(P<0.05);low expression of EGFR and CD3,group B median PFS was significantly longer than that in group A (P<0.05 ).Conclusion No matter low or high expression of VEGF and BRCA1 ,low expression of KRAS, ERCC1,EML4-ALK and β-tubulin and high expression of EGFR and CD3 in patients with non-small cell lung cancer may be more sensitive to the treatment of DP and gefitinib combined with recombinant human endostatin.
RESUMEN
Based on the result of oral 75 g glucose tolerance test (OGTT),55 pregnant women during the second trimester (gestational age 24-28 weeks) were selected and divided into gestational diabetes mellitus (GDM)group (n =25) and normal glucose tolerance (NGT) group (n =30).Women with GDM were older than those in NGT group.Blood glucose and insulin levels during the OGTT,incremental area under the glucose curve (AUCGLU) and insulin curve (AUCINs) during the OGTT,and basic insulin secretion index (HOMA-β) in the GDM group were higher compared with those in NGT group (P<0.05).However,in GDM group,insulin sensitivity index (ISI-Matsuda),dynamic insulin secretion index(Stumvoll 1-and 2-phase insulin secretion indices),and insulin secretion-sensitivity index (ISSI)were lowered (all P< 0.05),so was AUCINS/AUCGLU (P < 0.01),as compared with those in NGT group.Blood glucagon levels during OGTF and incremental area under the glucagon curve (AUCGL) showed no significant differences between 2 groups (P > 0.05).Multiple linear regression analysis showed that ISI-Matsuda,ISSI,HOMA-β,Stumvoll 1-and 2-phase insulin secretion indices accounted partially for the change of plasma glucose and ISI-Matsuda was the most important one among them.The function of islet α-cell seems to be normal while the function of β-cell is impaired in the patients with GDM,and failure of insulin secretion to overcome insulin resistance is the main reason for GDM.
RESUMEN
Objective To evaluate the safety and efficacy of percutaneous transluminal angioplasty (PTA) in treating Budd-Chiari syndrome (BCS) and to analyze the long-term follow-up results. Methods From October 1998 to May 2008,98 BCS patients (inferior vena cava obstruction,n = 34 ; hepatic vein obstruction, n = 22; combined obstruction, n = 42) who accepted PTA treatment successfully were investigated. The changes of clinical manifestations and liver function post-operation were observed; the long term survival rate was evaluated. Results Only two patients were complicated with transhepatic puncture tract bleeding, the prognosis was good after emergency operation. Sixty patients presented with low extremities edema, which was fully subsided after PTA.Of eighty-eight ascites patients, ascites disappeared in eighty patients after operation, and in the other eight patients combined with oral diuretic treatment post-operation. The median Rotterdam prognostic score of one month post-operation and the last follow-up time point was 0. 11 and 0. 09, significantly lowered than pre-operation (1.12). The difference was statistical significance (P=0. 000). At 1, 3, 5 years postoperative, the cumulative vessel patency rates were 96%, 94% and 94% respectively, and the cumulative survival rates were 94%, 91% and 87%. Conclusions Treating BCS with PTA has a high success rate, a good safety and a long-term survival rate.
RESUMEN
Totally 11 subjects with diabetic foot have been treated by umbilical cord blood mesenchymal stem cell (UCB-MSC) transplantation from November 2006 to October 2008 at the Chengyang People’s Hospital of Qingdao City. The course of disease was 6-18 years. Following over 6-months drug treatment and/or scaffold implantation, vascular bypass outcomes were bad. Of these patients, there were foot and/or lower limb cooling, pain, intermittent claudication and rest pain in 7 cases, abnormal color in foot skin in 7 cases, foot ulcer in 6 cases, gangrene in 4 cases, and concurrent infection in 2 cases. UCB-MSCs were obtained from healthy pregnant women, and supplied by Beike, Shenzhen, China. Following epidural or lumbar anesthesia, UCB-MSC suspension [cell number (1-6)?1011/L, 0.3-0.5 mL per point] was injected into affected lower extremity through multipoint muscles, with a distance among each point was about 3 cm ? 3 cm. Demixing injection could be performed in regions with plenty of muscles. At 1-4 weeks following transplantation, foot pain in 9 cases got amelioration or easement and cold sensation in 10 cases improved markedly. At 4-16 weeks after transplantation, foot ulcers were better and ulceration area reduced in 4 cases, gangrene area in 2 patients reduced and avoided amputation. 1 limb was amputated but with lowered level of amputation. After 12-24 weeks, 6 patients with intermittent claudication improved obviously, ankle-brachial index (ABI) increased in 3 cases, angiography showed an increase in visible collateral vessels in 3 patients. Transplantation of UCB-MSCs might be a simple, safe and effective method for patients with lower limb ischemia. It can effectively increase blood flow of lower limbs, promote ulcer healing and decrease amputation rate and amputation level.
