ABSTRACT
OBJECTIVE To provide reference for the management of antithrombotic therapy in thrombocytopenia patients with atrial fibrillation and atherosclerosis. METHODS The clinical pharmacist participated in the treatment of a thrombocytopenia patient with atrial fibrillation and atherosclerosis， and analyzed the causes of thrombocytopenia according to the patient’s medical history and laboratory examination results. At the same time， the risk of thrombosis-bleeding was evaluated according to the relevant guidelines， and the clinicians were assisted in formulating individual antithrombotic therapy plan and pharmaceutical care plan for the patient. The literature on antithrombotic therapy related to thrombocytopenia was collected and analyzed by retrieving CNKI. RESULTS Thrombocytopenia was considered as primary thrombocytopenia in this patient， and the main risk of bleeding was age ≥65 years old， bleeding tendency， and combined use of antithrombotic drugs. After the clinical pharmacist assessed the risk of thrombosis and bleeding， the clinician was recommended to give full dose of Bemiheparin sodium injection + Dronedarone hydrochloride tablets + Metoprolol succinate sustained-release tablets. In view of thrombocytopenia， the clinician gave Compound zaofan pill， Caffeic acid tablet and Sheng xuexiaoban capsule， but the patient developed diarrhea after the medication. The clinical pharmacist suggested stopping Sheng xuexiaoban capsule， and the clinician adopted the clinical pharmacist’s suggestion. When the patient was discharged from hospital， the clinical pharmacist suggested that the antithrombotic therapy plan for discharge was anticoagulation alone or selective anticoagulation. The clinician chose selective anticoagulation treatment considering that the patient’s current thrombocytopenia， urinary occult blood （+） and fecal occult blood were weakly positive， and ordered the patient to take Metoprolol succinate sustained-release tablets + Atorvastatin calcium tablets at discharge. Literature analysis showed that the causes of thrombocytopenia of patients with thromboembolism mainly included heparin induced-thrombocytopenia， immune thrombocytopenia， etc. All patients were improved after symptomatic treatment. CONCLUSIONS By participating in the management of antithrombotic therapy for the thrombocytopenia patient with atrial fibrillation and atherosclerosis， clinical pharmacists can help effectively control the patient’s condition and ensure the safety and effectiveness of drug use.
ABSTRACT
Objective To analyze the influence of different backpack types and loads on kinematics and plantar pressure of college students during stair climbing, so as to provide references for choosing the appropriate backpack and carrying mode. Methods The Nokov infrared light point motion capture system and Podome plantar pressure system were used to analyze the differences in the range of motion ( ROM) of the trunk and lower limb joints, the kinematic parameters at the peak time, the peak pressure of each plantar partition, the contact time, the maximum pressure of the whole foot, the average pressure and the maximum contact area for 15 male college students during the support period of stair climbing. Results The 5% BW and 10% BW backpack loads reduced ROM of trunk rotation, increased ROM of ankle flexion/ extension and varus / valgus. The 10% BW backpack loads increased the peak pressure of the 1st and 3rd metatarsals bones and the maximum pressure of the whole foot ( P < 0. 05). Single-shoulder bag and handbag reduced ROM of trunk tilting and rotation, and increased ROM of ankle flexion and extension, hip flexion angle, peak pressure of foot arch and medial heel (P<0. 05). The double-shoulder bag loads increased peak pressure in the toe area (P<0. 05). Conclusions During walking on the stairs, the 5% BW and 10% BW backpack loads limited trunk rotation and increased ankle ROM. The 10% BW loads also increased the load in metatarsal area. The unilateral weight-bearing mode would make the trunk tilt to the unload side and rotate to the weight-bearing side. The pressure in toe area was higher when carrying double-shoulder bag, while single-shoulder bag and handbag mainly increased the pressure of arch foot and medial heel. It is suggested that college students choose symmetrical backpack scheme, and wisely allocate back weight to avoid the injury of foot area.
ABSTRACT
OBJECTIVES@#Da Vinci robot technology is widely used in clinic,with minimally invasive surgery development. This study aims to explore the possible influence of advanced surgical robotics on the surgery learning curve by comparing the initial clinical learning curves of 2 different surgical techniques: robotic-assisted gastrectomy (RAG) and laparoscopic-assisted gastrectomy (LAG).@*METHODS@#From September 2017 to December 2020, a chief surgeon completed a total of 108 cases of radical gastric cancer from the initial stage, including 27 cases of RAG of the Da Vinci Si robotic system (RAG group) and 81 cases of LAG (LAG group). The lymph node of gastric cancer implemented by the Japanese treatment guidelines of gastric cancer. The surgical results, postoperative complications, oncology results and learning curve were analyzed.@*RESULTS@#There was no significant difference in general data, tumor size, pathological grade and clinical stage between the 2 groups (P>0.05). The incidence of serious complications in the RAG group was lower than the LAG group (P=0.003). The intraoperative blood loss in the RAG group was lower than that in the LAG group (P=0.046). The number of lymph nodes cleaned in the RAG group was more (P=0.003), among which there was obvious advantage in lymph node cleaning in the No.9 group (P=0.038) and 11p group (P=0.015). The operation time of the RAG group was significantly longer than the LAG group (P=0.015). The analysis of learning curve found that the cumulative sum analysis (CUSUM) value of the RAG group decreased from the 10th case, while the CUSUM of the LAG group decreased from the 28th case. The learning curve of the RAG group had fewer closing cases than that of the LAG group. The unique design of the surgical robot might help to improve the surgical efficiency and shorten the surgical learning curve.@*CONCLUSIONS@#Advanced robotics helps experienced surgeons quickly learn to master RAG skills. With the help of robotics, RAG are superior to LAG in No.9 and 11p lymph node dissection and surgical trauma reduction. RAG can clear more lymph nodes than LAG, and has better perioperative effect.

ABSTRACT
Objective To investigate the correlation between sexual dysfunction( SD) and estrogen receptor (ER) gene polymorphism in Chinese Han women with epilepsy (WWE). Methods A total of 112 married Chinese Han women with epilepsy were collected from outpatients and inpatients of the Affiliated Hospital of Yangzhou University,and 120 matched healthy women were taken as the control group. WWE were treated with antiepileptic drugs ( AEDs) for one year or more. The Chinese version of female sexual function index ( FSFI) was used to investigate the sexual function of the subjects. The chemiluminescence method was used to detect the sex hormones levels such as prolactin ( PRL),follicle-stimulating hormone (FSH),luteinizing hormone(LH),estradiol(E2),progesterone(P) and testosterone(T). Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) was used to determine the ER gene poly-morphism. Chi-square test,t-test and binary logistic regression were used for statistical analysis. The differ-ences of the sexual function,sex hormone,ER genotype,and allele frequency were compared between the two groups. And the correlation between SD and ER gene polymorphism was analyzed. Results ( 1) The pro-portion of SD in Chinese Han WWE was 70. 5%(79/112),while that was 24. 2%(29/120) in the control group. The serum prolactin (PRL) level in the WWE group was significantly higher than that in the control group (t=2. 072,P=0. 039). (2) The allele frequencies of ER PvuII C and AluI A in the WWE group were significantly higher than those in the control group (P=0. 001;P=0. 001). (3) Binary logistic regression a-nalysis showed that PvuII CC genotype and serum testosterone level were independently correlated with SD (OR= 6. 074, 95% CI: 1. 257-29. 352, P= 0. 025; OR= 0. 412, 95% CI: 0. 201-0. 842, P= 0. 015 ). Conclusion ERα PvuII polymorphism may be related to the susceptibility of SD in Chinese Han WWE,and PvuII CC genotype may be the risk genotype of SD in WWE.
ABSTRACT
Objective To investigate the incidence and related factors of sexual dysfunction in Chinese Han women with epilepsy (WWE).Methods A total of 112 cases of Han married WWE were continuously recruited from January 2015 to December 2017 in the Affiliated Hospital of Yangzhou University,and 120 matched non-epileptic healthy Han married women served as controls.The 112 WWE were classified as focal or comprehensive onset epilepsy and were treated with antiepileptic drugs (AEDs) for one year or more.Data collection was performed with a form inquiring about the participants' demographic parameters,including age,duration of marriage,education level,employment,monthly family income per capita,history of infertility and irregular menses.Details of epilepsy in WWE were investigated,including age of onset,duration of illness,seizure frequency,medication adherence.All participants were submitted to relevant scales and questionnaires (Female Sexual Function Index,Zung Self-Rating Anxiety Scale and Zung Self-Rating Depression Scale).In addition,WWE were evaluated by the 8-Item Morisky Medication Adherence Scale and the National Hospital Seizure Severity Scale.Chi-square test,t test and binary Logistic regression were used for statistical analysis.Results A high rate (70.5％,79/112) of sexual dysfunction was detected in WWE,whereas 24.2％ (29/120) in controls (x2=50.061,P＜0.01).Sexual dysfunction affected all dimensions:desire (85.7％,96/112),arousal (56.3％,63/112),lubrication (47.3％,53/112),orgasm (66.1％,74/112),satisfaction (58.9％,66/112) and pain (41.1％,46/112).Elevated rates of anxiety (40.2％,45/112),depression (33.0％,37/112) and poor medication adherence (31.3％,35/112) were also found in WWE.Binary Logistic regression showed that family economic status (monthly family income per capita ＜1 500 Yuan (OR=8.852,95％CI:1.469-53.346,P=0.017),monthly family income per capita 1 500-2 500 Yuan (OR=6.438,95％CI:1.439-28.796,P=0.015)),anxiety (OR=1.202,95％CI:1.050-1.375,P=0.008) and medication adherence (OR=0.371,95％CI:0.155-0.890,P=0.026) were associated with sexual dysfunction.Conclusions The associated factors of sexual dysfunction in Chinese Han WWE are multifactorial.WWE have higher levels of anxiety,poor family economic status and poor medication adherence.Medical professionals should not only better control seizures,but also evaluate and improve patients' sexual function,so as to improve the quality of life of WWE.
ABSTRACT
Objective To investigate the correlation between blood pressure variability (BPV) and early neurological deterioration (END) in patients with acute anterior circulation large artery atherosclerotic (LAA)stroke. Methods From January 2015 to June 2018, consecutive patients with anterior circulation acute ischemic stroke admitted to the Department of Neurology, the Affiliated Hospital of Yangzhou University were enrolled prospectively. According to the etiological classification, they were divided into LAA group and non-LAA group. By monitoring the blood pressure within 72 h of hospitalization, the mean, maximum (max)and minimum (min) values, and the difference between max and min (max-min), standard deviation (SD),and coefficient of variation (CV; CV = SD × 100/mean) were calculated. END was defined as the highest score of the National Institutes of Health Stroke Scale (NIHSS) within 72 h of admission increased by ≥2than the baseline. Multivariate logistic regression analysis was used to determine the correlation between BPV parameters and END. Results A total of 271 patients with anterior circulation acute ischemic stroke were enrolled, including 101 females (37. 3％) and 170 males (62. 7％), with an average age of 64. 99 ± 11. 51 years. There were 95 patients (35. 1％) with LAA and 176 (64. 9％) with non-LAA. In the LAA group and non-LAA group, 36 patients (37.9％) and 50 patients (28.4％) developed END respectively. The comparison between END patients and non-END patients in the LAA group showed that there were significant differences in age, sex, diabetes mellitus, baseline NIHSS score and C-reactive protein, as well as SBPmax , SBPmax-min , SBPSD , SBPCV, DBPmax , DBPmax-min , DBPSD , and DBPCV in BPV indices (all P < 0. 05).Multivariate logistic regression analysis showed that many BPV indices were the independent risk factors for END, including SBPmax (odds ratio [OR] 1. 027, 95％ confidence interval [CI] 1. 003-1. 052; P = 0. 027),SBPmax-min (OR 1. 041, 95％CI 1. 015-1. 068; P = 0. 002), SBPSD (OR 1. 177, 95％ CI 1. 048-1. 322; P =0. 006), SBPCV (OR 1. 226, 95％ CI 1. 036-1.451; P = 0. 018), DBPmax (OR 1. 073, 95％ CI 1. 017-1. 133;P = 0. 010), DBPmax-min (OR 1. 107, 95％CI 1. 044-1. 174; P = 0. 001), DBPSD (OR 1. 693, 95％CI 1. 268- 2. 260; P < 0. 001), and DBPCV(OR 1. 726, 95％CI 1. 311-2. 271; P < 0. 001). In the non-LAA group, there were no significant association between all BPV parameters and the occurrence of END. Conclusion BPV was significantly correlated with END in patients with anterior circulation LAA.
ABSTRACT
Objective To investigate the correlation between early blood pressure variability and early neurological deterioration (END) in patients with acute ischemic stroke.Methods Inpatients with acute ischemic stroke were collected prospectively.The blood pressure values of the enrolled patients were recorded continuously for 72 h after admission.The mean value (mean),maximum value (max),differences betw een the maximum and minimum (max-min),standard deviation (SD),and coefficient of variation (CV) for the systolic blood pressure (SBP) and diastolic blood pressure (DBP) were calculated.END was as an increase of at least 2 in the highest score of the National Institute of Health Stroke Scale (NIHSS) compared to the baseline.Multivariate logistic regression analysis was used to identify the independent correlation between the different blood pressure variability parameters and END following acute ischemic stroke after adjusting the confounding factors.Results A total of 128 patients with acute ischemic stroke were enrolled,including 53 females and 75 males,and their mean age was 63.30 ± 11.82 years.After standard treatment,35 patients (27.34％) developed END within 72 h after admission.There were significant differences in age,sex,diabetes mellitus,baseline NIHSS,C-reactive protein and SBPmax,SBP in,SBPSD,SBPCv,DBPmax,DBP max-min,DBPsD,and DBPCv between END group and non-END group (all P ＜0.05).Multivariate logisticregression analysis showed that SBPmax-min(odds ratio [OR] 1.040,95％ confidence interval [CI] 1.014-1.067,SBPsD(OR 1.191,95％ CI 1.052-1.347),SBPCv(OR 1.317,95％ CI 1.100-1.578),DBP max-min(OR 1.076,95％ CI 1.018-1.138),DBPsD(OR 1.508,95％ CI 1.128-2.016),and DBPCv(OR 1.338,95％ CI 1.093-1.638) in blood pressure variability indices were the independent risk factors for END in patients with acute ischemic stroke.Conclusion Blood pressure variability is significantly associated with END within 72 h after admission in patients with acute ischemic stroke.
ABSTRACT
Objective To explore the clinical manifestations ,risk factors and treatment of antibiotic asso-ciated diarrhea(AAD)in senile patients with severe bacterial pneumonia. Methods Retrospective analysis was made on senile patients of bacterial pneumonia combined with antibiotic associated diarrhea. Results There were 114 patients out of 572 cases had AAD. The incidence of AAD in these senile patients was 19.93%. There were 62.28% patients more than 80 years old. The incidence AAD was 37.3% with third generation cephalosporin treat-ment,28.6% penicillin with enzyme inhibitor treatment and 19.2% with carbopenems treatment. Conclusions The high risk factors of AAD in senile patients with bacterial pneumonia include patient′s age,and time, APACHE Ⅱ,category,combination therapyof antibacterial,and invasive operations. We should pay more atten-tion to AAD and related high risk factors when using these antibiotics in clinics. Rational selection and use of anti-bacterial are important measures to stop senile patients from ADD. Pharmaceutical care could help to optimize the treatment plan and reduce its adverse reaction of antibacterial in senile patients.

ABSTRACT
OBJECTIVE:To investigate the clinical characteristics and gene polymorphism of oxcarbazepine (OXC)- induced Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN). METHODS:Retrieved from CNKI,Wanfang,VIP, PubMed,EMBase,SpringerLink and other databases,case reports about OXC-induced severe ADR were summarized and ana-lyzed. RESULTS:Twelve literatures were collected,and 13 case reports about OXC-induced SJS/TEN were obtained. Male had more OXC-induced severe skin ADR than female. ADR mostly occurred during 1-14 d after medication. All patients were cured with treatment of glucocorticoid and antiallergy,without death case. Genotyping for 8 patients were performed and 6 of them showed the presence of HLA-B*1502 allele. While HLA-B alleles of 2 patients were HLA-B*1518/B*4001,which was the variation of HLA-B*1502. CONCLUSIONS:OXC-induced ADR should be monitored closely. Great importance should be attached to patient education and follow-up program. HLA-B*1502 gene detection should be performed to guide rational use of OXC and optimize clini-cal drug use plan.

ABSTRACT
Objective To investigate the correlation between hemorrhagic transformation (HT) and each parameter of blood pressure variability (BPV) in patients with massive cerebral infarction caused by cardioembolic middle cerebral artery occlusion. Methods The patients with massive cerebral infarction caused by unilateral cardioembolic middle cerebral artery occlusion admitted to hospital within 24 h after onset were selected. For patients without revealing HT with head MRI on admission were analyzed retrospectively. According to the results of MRI rescan within 7 days after onset, they were divided into either a HT group or a non-HT group. Al specific parameters of blood pressure were compared and analyzed between the 2 groups, specificaly including initial value (initial), mean value ( mean), maximum value (max), minimum value (min), maximum-minimum difference (max-min), standard deviation (sd), successive variation (sv), and maximum value of sv (svmax) of systolic blood pressure (SBP) and diastolic blood pressure (DBP). Results A total of 146 patients were enroled in the analysis, and 77 (52. 7% ) had HT within 7 d after onset. Al the blood pressure parameters were grouped by quartiles. Multivariate logistic regression analysis showed that after adjusting for age, admission time, baseline National Institutes of Health Stroke Scale score, congestive heart failure, antiplatelet therapy, initial blood glucose, prothrombin time, and international normalized ratio of the patients, SBPmin , SBPmax-min , SBPsv , SBPsvmax , DBPinitial, DBPsd , DBPmax , DBPmax-min , DBPsv , and DBPsvmax had significant independent association with and HT (likelihood ratio test of trend, al P < 0. 05). Conclusions Higher BP level and variability may increase the risk of HT in patients with massive cerebral infarction after cardioembolic middle cerebral artery occlusion. A smooth and slow antihypertensive treatment may need for these patients.
ABSTRACT
Objective To explore the effects of two lubricants on skin preparation from donor site in patients with skin flap transplantation. Methods According to digit number table, 83 patients undergoing wound repair using modified fascia flap were divided into observation group (n=41) and control group (n=42). The former group were treated with Johnson K-Y Lubricant, while the latter with talcum powder. The two groups were compared in terms of the skin flap quality from donor site, pain degree and number of bacteria before and after transplantation. Results There was no significant difference in bacteria number before and after transplantation in the two groups (P>0.05), but the difference between the groups was significant (P<0.01). The flap preparation quality in the observation group was significantly better than that of control group and the pain degree was significantly lower than that of observation group. Conclusion Johnson K-Y Lubricant can significantly improve flap preparation quality and reduce pain.
ABSTRACT
Objective To observe the variation of helper T cell (Th)9/regular T cell (Treg cell) balance in the inflammatory process of hepatitis B virus (HBV) infection.Methods Two hundred patients with chronic HBV infection in Zhejiang Hospital of Integrated Traditional and Western Medicine during August 2011 to June 2012 were divided into four groups according to alanine aminotransferase (ALT) levels.:chronic HBV carriers,chronic hepatitis B (CHB) with mildly [upper limit of normal (ULN)＜ALT＜3 × ULN],moderately (3 × ULN＜ALT＜5 × ULN),or significantly (ALT＞5 × ULN) elevated ALT,with 50 subjects in each group.In addition,30 healthy volunteers were enrolled as healthy controls (HC).ALT levels,HBV DNA,and Th9/Treg levels were measured by automatic biochemical analyzing equipment,real-time fluorescent quantitative polymerase chain reaction and flow cytometry,respectively.Th9/Treg levels of each group were observed.Means between groups were compared by t test,means of multiple groups were compared by one-way analysis of variance.Spearman rank correlation was used for correlation analysis.Results Age,sex distribution and HBV DNA levels of the four groups were comparable (P＞0.05).ALT levels of HC were significantly different from those of mildly,moderately,or significantly elevated ALT (t=8.48,18.41,28.93; all P＜0.05).Th9 cell levels,Treg cell levels and Th9/Treg ratio of HBV infected individuals were significantly different from those of HC (P＜0.05).With the increasing degree of inflammation,proportion of Th9 cells increased and Treg cells decreased gradually.The differences among the four groups were of statistical significance (P＜ 0.05).Th9 cell level was positively correlated with ALT (r=0.804,P=0.01),while Treg cell level was negatively correlated with ALT (r=-0.828,P=0.01).Conclusions Th9/Treg is imbalanced in patients with HBV infection,and closely correlated with ALT levels.
