Fu biao who got an advanced liver cancer had undergone liver-transplantation twice and died at last,which raises great ethical concern.With respect to distribution,there are four substantial distributive principles,including the principle of equality,the principle of need,the principle of contribution,the principle of effort.When allocating scarce health-care resouses,medical criteirion should be considered firstly the equality of everyone's life.Furthermore,the principle of utility and equality should be embodied for ensuring distributive justice.

Objective To.investigate the accuracy and reliability of monocyte count of three methods.Methods The specimens classified by blood cell analyzer WBC monocytes ＜ 15％,15％-20％,＞ 20％ were taken randomly,draw 20 μ l after mixing,put in monocyte direct count dilution and count,and underwent routine smear,stained by Swiss-Gibbs and manual classified by microscope,and then compared the results of the three methods.Collected one copy each of the high,medium and low proportion of monocytes specimens,and counted 30 times by the three counting method.Results Blood cell analyzer in WBC monocytes 15％-20％,＞ 20％ had poor correlation with the results of the other two methods.Repeatability comparison of three methods,medium and low sample were better with method 1 and 2,high value sample was good with method 3.Conclusion The specimens of monocytes ≥ 15％,especially scatter plot is abnormal,must be confirmed by microscopic examination.

Objective To report the result of analysis of 72 cases of facial cutaneous sporotrichosis. Methods Seventy-two patients were included in this study. They were diagnosed as facial cutaneous sporotrichosis according to clinical mainfestations and fungal culture. Histopathological examinations were done in some atypical cases. The patients were treated with combined antifungal agents. Results The lesion forms were varied, in which lymphangitic cutaneous form accounted for 9.72% and fixed cutaneous form accounted for 90.28% respectively. Nineteen cases (26.4%) had a history of skin trauma before the cutaneous lesions. All of the patients were successfully treated with potassium iodide and/or itraconazole, terbinafine for 6-8 weeks. Conclusions The skin lesions and mycological examination are the important evidences for the diagnosis of sporotrichosis. The main form of the facial cutaneous sporotrichosis is the fixed cutaneous form. The misdiagnosis rate is 16% in primary level clinics. Potassium iodide is an effective and inexpensive medicine in the treatment of cutaneous sporotrichosis.

Objective To assess the differences in carotid artery stiffness properties and endothelium-independent dilation (EID)between elderly and young patients,and evaluate the echotracking (ET)system for vascular stiffness at different ages.Methods A total of 79 outpatients with multiple cardiovascular risks were recruited.Clinical data including medical history,height,weight,blood pressure,fasting blood glucose and blood lipid were collected.We evaluated the arterial stiffness parameters of carotid artery and EID using an ultrasonic ET system in 46 elderly subjects,compared with 33 sex-matched non-elderly subjects.The impaired EID function was defined as brachial artery nitroglycerin mediated dilation (NMD)below 4％.Results All stiffness parameters including pressure-strain elasticity modulus stiffness index β (Ep),pulse wave velocity β (PWVβ)and augmentation index (AI)were significantly increased in elderly group compared with the non-elderly group [(138.9±64.7)kPa vs.(100.6±30.8)kPa,(10.9±4.7)vs.(8.2±2.3),and (6.9±1.4)m/s vs.(6.1±0.9)m/s,P＜0.05 respectively],while the exception of arterial compliance (AC)was reduced (0.9±0.3)mm2/kPa vs.(1.0±0.5)mm2/kPa(P＜0.05).The incidence of impaired EID in elderly group was higher than in non-elderly group [56.5％ (26 cases) vs.33.3％ (11 cases),P＜0.05].ET parameters including Ep,stiffness index β,PWVβ,AC and AI were related to age (r=-0.44,-0.45,-0.40,-0.40,0.34,all P＜0.01)； Ep,stiffness index β,PWVβ and AC were also related to impaired EDI (r=-0.38,-0.40,-0.34,-0.29,all P＜0.01).Conclusions Arterial stiffness properties and EID measured by ET system was more serious in elderly with multiple cardiovascular risks than in non-elderly subjects.As a convenient and accurate assessment of stiffness parameters,ET system is optimal option for measuring arterial stiffness and EID in elderly people.

High-affinity α-glucosidase inhibitors were screened from Cichorium glundulosum Boiss.et Hout seed (CGS) extract by ultra-filtration affinity-liquid chromatography-mass spectrometry (UF-LC-MS) and molecular docking.By taking 4-nitrobenzene-α-D-glucopyranoside (PNPG) as substrate and acarbose as positive control to evaluate the inhibitory activity of CGS extract, IC50 of acarbose and CGS extract were 0.003 mg/mL and 0.447 mg/mL, respectively.Meanwhile, 4 compounds from CGS extract by UF-LC-MS were screened and identified.Then by using autodock software, the compounds that combined with α-glucosidase were well screened out, including chlorogenic acid and isochlorogenic acid A.The inhibitory activity of chlorogenic acid and chlorogenic acid A against α-glucosidase was verified in vitro.The results showed that the inhibitory activity of the compounds toward α-glucosidase presented the sequence of acarbose>isochlorogenic acid A>chlorogenic acid.The inhibition rate of isochlorogenic acid A was close to acarbose.The experimental results illustrated that UF-LC-MS and molecular docking could be used to screen high affinity enzyme inhibitors from CGS.

Objective:To explore the application of real-time transrectal ultrasound (TRUS) during seminal vesiculoscopy in infertile men with azoospermia or oligoasthenospermia.Methods:We retrospectively analyzed the clinical data of 25 cases of azoospermia or oligoasthenospermia due to ejaculate ducts obstruction who were treated with real-time transrectal ultrasound-guided seminal vesiculoscopy between September 2011 and December 2015. Patients’ age was(29.4±4.5) years. All patients accepted semen analysis, serum sex hormone, MRI, TRUS and then diagnosed as obstructive azoospermia, and 13 cases had intractable obstructive azoospermia or oligoasthenospermia after the failure of simple seminal vesiculoscopy(the path to the ejaculatory duct and seminal vesicle couldn’t be found). All patients were treated with seminal vesiculoscopy under real-time guidance with TRUS. We assessed the success rate of surgery, surgical time and complications.Results:The scope was successfully inserted into the seminal vesicle in 21 of the 25 cases (success rate, 84%). The median operative time was 75(31, 148) min. None of the patients developed severe complications. Among 4 failure cases (4/25, 16%), 1 was due to abnormal congenital development. In 2 cases, a clear outlet of the dual ejaculatory duct could not be found after it was inserted into the prostatic utricle. One case was considered as a Müllerian tubular cyst, and the seminal vesicle scope was used to assess the cystic side wall. The 21 patients were followed up for 3 to 6 months, semen volume 2.0(0-5.2)ml, total sperm 28(0-832) ×10 6/ejaculate, sperm density 5.6(0-110.3)×10 6/ml, mobility rate of sperm 5.4%(0-63.6%), and the differences were significant as compared to that before the surgery [semen volume 0.4(0-2.8)ml, total sperm 0(0-342)×10 6/ejaculate, sperm density 0(0-90.7)×10 6/ml, mobility rate of sperm 0(0-24.1%), all P<0.05]. Among the 17 patients who underwent follow-up of 5 to 9 years, 3 patients was conceived naturally and 9 patients’ postoperative sperm quality has improved and pregnancy in vitro fertilization by extracting sperm from semen. Conclusions:Intraoperative real-time transrectal ultrasound guidance can improved the success rate of seminal vesiculoscopy and promoted operative safety.

Objective:To compare the surgical outcomes of robotic natural orifice specimen extraction surgery (NOSES) and robotic-assisted radical resection for rectal cancer.Methods:A retrospective analysis using propensity score matching (PSM) was conducted on 547 patients who had undergone radical resection of rectal cancer at the First Affiliated Hospital of Nanchang University from June 2018 to March 2024. The study cohort comprised 157 patients in the robotic NOSES group and 390 in the robotic-assisted group. PSM was used in a 1:1 manner to match relevant general clinical preoperative data of the study patients (age, sex, body mass index, preoperative comorbidities, abnormal preoperative carcinoembryonic antigen (>6.5 μg/L) and carbohydrate antigen 19-9 levels (>27 kU/L), preoperative American Society of Anesthesiologists score, tumor diameter, tumor distance from the anal margin, and TNM stage), with a clamp value of 0.05. After performing PSM to match the general clinical data of the two groups of patients, 77 patients in each of the robotic NOSES and robotic-assisted groups were included in the analysis. We found no statistically significant difference in preoperative general clinical data between the robot NOSES and robot-assisted groups ( P>0.05). We compared the surgical outcomes, postoperative recovery, postoperative pathological data, and incidence of complications between the robotic NOSES and robot-assisted groups. Results:Compared with the robot-assisted groups. the robot NOSES group had a significantly shorter time to first postoperative passage of flatus (48 [38, 50] hours vs. 56 [50, 60] hours, Z=-7.513, P<0.001), time to taking a liquid diet (60 [54,63] hours vs. 66 [62, 72] hours, Z=-6.303, P<0.001), lower pain scores (3 [3, 4] vs. 4 [4, 5], Z=-5.237, P<0.001), and lower incision infection rates (0 vs. 5 [6.5%], χ 2=5.237, P=0.028) within 24 hours after surgery ( P<0.05). However, there were no significant differences in surgical time, intraoperative blood loss, postoperative hospital stay, postoperative anastomotic complications, or incidence of other complications between the two groups (all P>0.05). Conclusion:Robotic NOSES surgery is a safe and feasible procedure for resecting rectal cancer and postoperative recovery is faster after robotic NOSES than after standard robot-assisted surgery.

OBJECTIVE To study the efficacy evaluation of triptolide(TP) in rats with cerebral ischemia-reperfusion(I/R) injury and its mechanism. METHODS Rat brain I/R injury model was copied by middle cerebral artery wire embolism surgery, and TP (0.1, 0.2 mg·kg−1) was given to the treatment group, and set the sham surgery group. The Longa score method was used to measure the neural function of rats, and Niselferi staining was used to show the morphology of neurons in the ischemic side brain tissue of rats, immunofluorescence was used to detect the expression levels of MAP2 and Syn in ischemic lateral brain tissue. The expression levels of cAMP, PKA, BDNF, Syn and PSD-95 were detected by Western blotting. RESULTS Compared with the model group, the neurological scores of TP treatment group decreased significantly(P<0.01 or P<0.001), it had a protective effect on damaged neurons. Compared with the model group, cAMP, PKA, BDNF, Syn and PSD-95 in TP treatment group were significantly up-regulated. CONCLUSION TP treatment can significantly improve I/R injury, and the mechanism may be related to the activation of the cAMP/PKA/BDNF signaling pathway.
