ABSTRACT
OBJECTIVE@#To evaluate the efficacy and safety of Jianpi Jieyu Decoction (JJD) for treating patients with mild-to-moderate depression of Xin (Heart)-Pi (Spleen) deficiency (XPD) syndrome.@*METHODS@#In this multi-center, randomized, controlled study, 140 patients with mild-to-moderate depression of XPD syndrome were included from Xiyuan Hospital of China Academy of Chinese Medical Sciences and Botou Hospital of Traditional Chinese Medicine from December 2017 to December 2019. They were randomly divided into JJD group and paroxetine group by using a random number table, with 70 cases in each group. The patients in the JJD group were given JJD one dose per day (twice daily at morning and evening, 100 mL each time), and the patients in the paroxetine group were given paroxetine (10 mg/d in week 1; 20 mg/d in weeks 2-6), both orally administration for a total of 6 weeks. The primary outcome was the change of 17-item Hamilton Depression Rating Scale (HAMD-17) score at week 6 from baseline. The secondary outcomes included the Hamilton Anxiety Scale (HAMA) score, Traditional Chinese Medicine Symptom Scale (TCMSS), and Clinlcal Global Impression (CGI) scores at the 2nd, 4th, and 6th weekends of treatment, HAMD-17 response (defined as a reduction in score of >50%) and HAMD-17 remission (defined as a score of ⩽7) at the end of the 6th week of treatment. Adverse events (AEs) were also recorded.@*RESULTS@#From baseline to week 6, the HAMD-17 scores decreased 10.2 ± 4.0 and 9.1 ± 4.9 points in the JJD and paroxetine groups, respectively (P=0.689). The HAMD-17 response occurred in 60% of patients in the JJD group and in 50% of those in the paroxetine group (P=0.292); HAMD-17 remission occurred in 45.7% and 30% of patients, respectively (P=0.128). The differences of CGI scores at the 6th week were not statistically significant (P>0.05). There were significant differences in HAMD-17 scores between the two groups at 2nd and 4th week (P=0.001 and P=0.014). The HAMA scores declined 8.1 ± 3.0 and 6.9 ± 4.3 points from baseline to week 6 in the JJD and paroxetine groups, respectively (P=0.905 between groups). At 4th week of treatment, there was a significant difference in HAMA between the two groups (P=0.037). TCMSS decreased 11.4 ± 5.1, and 10.1 ± 6.8 points in the JJD and paroxetine groups, respectively (P=0.080 between groups). At the 6th week, the incidence of AEs in the JJD group was significantly lower than that in the paroxetine group (7.14% vs. 22.86%, P<0.05).@*CONCLUSION@#Compared with paroxetine, JJD was associated with a significantly lower incidence of AEs in patients with mild-to-moderate depression of XPD syndrome, with no difference in efficacy at 6 weeks.

Objective:To explore the value of IL-6 in the diagnosis, treatment and improving prognosis of urosepsis at 2 hours after percutaneous nephrolithotomy.Methods:Twenty-five patients with urosepsis undergoing percutaneous nephrolithotomy in the Shandong Provincial Hospital Affiliated to Shandong First Medical University from January 2019 to June 2021 were analyzed retrospectively, including 6 males and 19 females, aged (55.4±11.6) years, and there were 10 cases with hypertension, 11 cases with diabetes and 14 cases with hydronephrosis. There were 10 cases with Stone volume>353mm 2, 22 cases with pyuria, 12 cases with positive nitrite and 18 cases with positive urine culture before operation. Among them, 13 patients were classified into experimental group with the test of IL-6 at 2 hours after operation and 12 patients were classified into control group without the test of IL-6 at 2 hours after operation. IL-6>1 000 pg/ml at 2 hours after operation as the standard for diagnosis of urosepsis was used to guide the anti-infective treatment after percutaneous nephrolithotomy. The operation time, severity of urinary sepsis (severe sepsis and septic shock), diagnostic time of urosepsis after operation, and hospital stay after operation were compared between the two groups. Results:There were 13 patients including 9 females with average age of (52.4±12.2) years in the experimental group, and there were 6 cases with hypertension, 5 cases with diabetes and 9 cases with hydronephrosis, 5 cases with stone volume>353mm 2, 12 cases with pyuria, 7 cases with positive nitrite and 10 cases with positive urine culture before operation. There were 12 patients including 10 females with average age of (58.7±10.5) years in the control group, and there were 4 cases with hypertension, 6 cases with diabetes, 5 cases with hydronephrosis, 3 cases with stone volume>353mm 2, 10 cases with pyuria, 5 cases with positive nitrite, and 8 cases with positive urine culture before operation. There was no significant difference between the two groups in terms of gender( P=0.645), average age ( P=0.182), hypertension( P=0.688), diabetes( P =0.695), hydronephrosis( P=0.238), stone volume>353 mm 2( P=0.673), pyuria( P=0.593), positive nitrite( P=0.695), and positive urine culture( P=0.673). There was not significant difference in the general clinical data of gender, age, hypertension, diabetes, stone burden, hydronephrosis, pyuria, positive nitrite and positive urine culture between the two groups ( P>0.05). The mean value of IL-6 in the test group was (6 824.4±1 473.3) pg/ml. The operative time of the experimental group with (100.8±27.8) minutes was longer than that of the control group with (88.3±39.3) minutes, but the difference between the two groups was not statistically significant ( P=0.645). The diagnostic time of urosepsis after operation in the test group with (3.6±2.0) hours was shorter than that in the control group with (6.0±3.0) hours, and the difference between the two groups was statistically significant ( P=0.023). The postoperative hospital stay in the test group with (6.1±1.6) days was shorter than that in the control group with (8.2±2.3) days, and the difference between the two groups was statistically significant ( P=0.014). Three patients with severe sepsis and septic shock in the test group, which were less than that of eight patients with severe sepsis and septic shock in the control group, and the difference between the two groups was statistically significant ( P=0.047). Conclusion:The detection of IL-6 at 2 hours after percutaneous nephrolithotomy can early diagnose urosepsis, reduce the severity of postoperative urosepsis, shorten the postoperative hospital stay, and improve the prognosis.
ABSTRACT
Sjögren syndrome （SS） is a chronic autoimmune disease characterized by immune cell infiltration and progressive destruction of salivary and lacrimal glands. It not only affects the lacrimal and salivary glands， manifested as dry eyes and dry mouth， but also involves heart， lung，kidney，and central nervous system， seriously affecting human physical and mental health. Although western medicine has made extensive and in-depth research on the diagnosis and treatment of this disease in recent years，there is no effective treatment targeting the potential causes. Chinese medicine emphasizes the concept of holism，treatment and prescription formulation based on syndrome differentiation， and effect exertion via multiple targets，multiple levels，and multiple pathways，exhibiting great advantages in the treatment of SS. This paper reviews the mechanisms of Chinese medicine in treating SS from the perspectives of immunity regulation，aquaporin up-regulation， and anti-oxidative stress reported in the related literature，so as to provide more theoretical basis for the research and clinical treatment of SS.
ABSTRACT
To investigate the inhibitory effect of Huangqi Danshen decoction (HDD) on isoproterenol (ISO)-induced myocardial remodeling and explore its effect on STIM1, TRPC1, CaN and NFATc3 expressions. ISO (2.5 mg•kg⁻¹•d⁻¹×14 d) was given by subcutaneous injection to establish myocardial remodeling models in rats, and then were randomly divided into control group, ISO model group, HDD5 group (HDD 5 g•kg⁻¹•d⁻¹+ISO), and HDD10 group (HDD 10 g•kg⁻¹•d⁻¹+ISO). After intervention for 4 weeks, the heart mass index (HW/BW) and the left ventricular mass index (LVW/BW) were calculated; the structure of myocardium was observed by echocardiography; the pathological changes of myocardium were observed by HE staining; levels of BNP, CaN and CaM kinases II in serum were detected by ELISA, and the protein expression levels of STIM1, TRPC1, p-CaN, p-NFATc3, and NFATc3 in left ventricular tissues were detected by Western blot. The results showed that the HW/BW and LVW/BW in ISO group were greater than those in HDD5 group and HDD10 group (P<0.05); Echocardiography showed that HDD inhibited ISO-induced increase in LVEDD and LVESD; ELISA results showed that HDD could significantly inhibit the increase of BNP, CaN and CaM kinases II levels in serum of rats with ISO-induced myocardial remodeling (P<0.01). Western blot results showed that STIM1, TRPC1, p-CaN, p-NFATc3 and NFATc3 expression levels were increased in the myocardial tissues of ISO group rats, and after HDD administration, the above expression levels were decreased in group ISO, HDD for myocardial tissue after administration of STIM1, TRPC1, p-CaN, p-NFATc3 and NFATc3 expression decreased (P<0.05). Our findings indicated that HDD can attenuate the myocardial remodeling induced by ISO, and its mechanism may be related to down-regulating the expression levels of STIM1, TRPC1, CaM kinases II, p-CaN/CaN and p-NFATc3/NFATc3.
ABSTRACT
Objective To evaluated the safety and feasibility of excimer laser atherectomy (ELA) combined with drug-eluting balloon angioplasty in treating chronic ischemia of lower limbs.Methods ELA combined with paclitaxel-eluting balloon angioplasty was adopted to treat chronic ischemia of lower limbs caused by arteriosclerosis occlusive disease of lower extremity in three patients.All three patients had arteriosclerosis occlusive disease of superficial femoral artery;in two of them the disease was primary occlusive lesion and in another patient the disease was in-stent re-occlusion lesion after sten implantation.Results After the treatment,the blood flow in the diseased arteries was unobstructed,the blood supply of the lower limbs was obviously improved.No procedure-related complications occurred.Two weeks after the treatment,no recurrence of ischemic symptoms was observed,the blood flow in superficial femoral artery kept unobstructed.The patients recovered smoothly.Conclusion For the treatment of chronic ischemia of lower limbs,which are caused by the primary arteriosclerosis occlusive disease of lower extremity or by the in-stent re-occlusion lesion after sten implantation,ELA combined with paclitaxel-eluting balloon angioplasty is clinically safe and feasible,although its long-term effect needs to be clarified with more studies.

ABSTRACT
Objective To evaluate early changes of femoral artery elasticity in type 2 diabetes mellitus (T2DM) combined with microalbuminuria (MA) patients using ultrasound radio-frequency technology,and to study the clinical significance.Methods 51 T2DM without MA patients were enrolled in Group A,and 53 T2DM with MA patients were enrolled in Group B.In order to observe the early elastic changes in the subjects,two-dimensional ultrasound was used to eliminate patients whose intima-media thickness (IMT) was ＞1 mm.The femoral arteries were imaged by two-dimensional ultrasonography,and then the IMT,femoral artery inner diameter (D),distensibility coefficient (DC),compliance coefficient (CC),elasticity coefficient (α and β),and pulse wave velocity (PWV) were real-time tested using quality intima-media thickness (QIMT) and quality arterial stiffness (QAS) analyzing systems.Besides,the differences and correlation analyses of these parameters between the two groups were conducted.In addition,some other parameters of sujects in both group A and B were also determined and analysed,including total cholesterol (TC),triglyceride (TG),low-density lipoprotein cholesterol (LDL-C),high-density lipoprotein cholesterol (HDL-C),creatinine (CREA),glycosylated hemoglobin (HbA1c),fasting blood glucose (FPG),2h postprandial plasma glucose (2hPG) and body mass index (BMI).Results There were no significant differences in the elastic parameters of femoral arteries between the male and female subjects (P＞0.05),and between left and right sides (P＞0.05) within a same group.Compared with group A,group B had lower CC and DC (P＜0.05) and higher α,β and PWV (P＜0.05).Pearsons correlation analysis indicateal that,CC was negatively correlated with α,β and PWV (P＜0.05),and DC was also negatively correlated with α,β and PWV (P＜0.05).There was no significant difference in the inner diameters of femoral arteries between the two groups (P＞0.05).The levels of TG,HbA1c,FPG and 2hPG in group B were significantly higher than those in group A (P＜0.05).There were no significant differences in TC,HDL-C,LDL-C,CREA and BMI between the two groups (P＞0.05).Conclusions The decrease of arterial elastic function is earlier than morphological changes,that is,it may have occurred before MA in T2DM patients.The application of ultrasound radio-frequency analyzing technology has certain significance in the clinical early diagnosis and treatment.
