Curcumae Rhizoma, derived from the rhizome of Curcuma phaeocaulis, Curcuma kwangsiensis and Curcuma wenyujin, was called Ezhu in China. In the past, Curcumae Rhizoma extracts were obtained through water decoction or alternative methods, which showed significant anti-cancer effects. However, the mixed extracts contain various compound components of Curcumae Rhizoma, leading to an ambiguous mechanism of action for Curcumae Rhizoma extracts anti-cancer. Contemporary researchers have extracted the chemical components of Curcumae Rhizoma separately for experimental verification of its active ingredients in the anti-cancer field. Numerous studies demonstrated that curcumol, germacrone, β-elemene, and curcumin in Curcumae Rhizoma extracts have significant governing effects in anti-cancer activities. Pharmacological studies have shown that Curcumae Rhizoma suppresses cancer cell proliferation, invasion, and migration, triggering apoptosis and regulating cellular autophagy to achieve anticancer effects. Here, we summarized the research progress of Curcumae Rhizoma on anti-cancer effects from 2013 to 2022, aiming to explore the deeper molecular mechanisms of Curcumae Rhizoma's active components in cancer treatment.

Objective:To evaluate the imaging stability of a portable boom-type ophthalmic ultra-high-resolution optical coherence tomography (OCT) device in multiple application scenarios.Methods:The boom-type mode and handheld mode of the portable boom-type OCT and the desktop OCT were used to perform three-dimensional imaging tests on three healthy adults undergoing physical examinations at the Zhongshan Ophthalmic Center, Sun Yat-sen University as well as on OEMI-7 model eyes in a sitting position.The same two modes of the portable boom-type OCT were used to perform three-dimensional imaging on four awake non-sedated infants, two sedated infants and four healthy adults in the supine position.The obtained 3D imaging data were processed using a correlation analysis method between adjacent B-scans, and the offset of B-scan in the axial (z-axis) and the fast axis transverse (x-axis) were calculated.The procedures for in vivo human eye experiments followed the Declaration of Helsinki and were approved by the Ethics Committee of Zhongshan Ophthalmic Center, Sun Yat-sen University (No.2020 KYPJ154).All subjects and infant guardians signed the informed consent form. Results:Compared with the handheld imaging mode, the axial and fast axis lateral motion offsets of the model eye were significantly reduced in the boom-type imaging mode from (124.00±12.49)μm to (48.00±15.87)μm and from (24.00±1.00)μm to (2.67±0.57)μm, respectively ( t=2.932, 4.337; both P<0.001).In both human and model eyes, the axial and fast axis lateral motion offsets of the boom-type mode were significantly lower than in the traditional handheld operation mode (both P<0.001).The axial and lateral motion offsets between the boom-type mode and desk-top OCT imaging were comparable, without significant differences (both P>0.05).In both sedated and awake, non-sedated infants in the supine position, the axial offset of the portable boom-type OCT system was similar to that of the healthy adults, without significant difference in the overall comparison ( P=0.385), and the lateral offsets were higher than those of healthy adults, with statistically significant differences (both P=0.013).There was no significant difference in axial deviation between sedated and non-sedated infants ( P>0.05).The lateral deviation of non-sedated infants was higher than that of sedated infants, though the difference was not statistically significant ( P=0.247). Conclusions:The portable boom-type OCT system can maintain high-speed, high-resolution imaging performance while achieving imaging stability comparable to traditional desktop OCT systems.It is more suitable for bedside imaging of supine subjects, especially uncooperative infants, and has good clinical application prospects.

Objective:To observe the effect of contralateral controlled functional electrical stimulation (CCFES) on the recovery of upper limb motor function after a stroke.Methods:Stroke survivors 1 to 6 months after onset were randomly divided into a CCFES group (14 cases, group A), a CCFES intensive group (14 cases, group B) and a neuromuscular electrical stimulation group (15 cases , group C). In addition to routine rehabilitation training, groups A and B received contralateral controlled functional electrical stimulation, while Group C received routine neuromuscular electrical stimulation. Group B was treated twice daily, while the other two groups were given 1 session each day, 5 times a week for 3 weeks. Each session lasted 20 minutes. The Fugl-Meyer assessment (FMA), the Modified Barthel Index (MBI), surface electromyography and the active range of motion for wrist dorsiflexion were used to evaluate the subjects′ upper limb function before and after the treatment.Results:There was no significant difference in any of the measurements among the three groups before the treatment. After the treatment, all of them had improved significantly, with the improvements in groups A and B significantly greater than in group C, on average.Conclusions:Both normal and intensive contralateral controlled functional electrical stimulation have significant advantages over neuromuscular electrical stimulation in promoting functional recovery of the upper limbs. Intensive CCFES training is superior to routine training in improving muscle strength and range of motion.

Objective To explore the early laboratory indicators for risk of intravenous immunoglobin-resistant Kawasaki diseases. Methods The clinical data were retrospectively analyzed in 881 Kawasaki disease patients (group A: 26 cases of intravenous immunoglobin-resistant; group B: 855 cases of intravenous immunoglobin-sensitive) from July 1, 2015 to June 30, 2016. After 1:3 matching with age and sex, the regression model for each of variables including sex, age, fever days, temperature, red blood cell count (RBC), white blood cell count (WBC), neutrophil (N), lymphocyte (L), platelet count (PLT) and C reactive protein (CRP), was constructed by conditional logistic regression analysis. Results Compared with group B, group A had significantly lower RBC count and higher PLT (P<0.05). Logistic regression analysis showed that, with the age, the regression model was Y=-2.87+0.01×PLT (PLT OR=1.01, 95％ CI: 1.00～1.01, P<0.01); with the sex, Y=-32.98+0.44×WBC+0.28× N+0.01×PLT (WBC OR=1.55, 95％ CI: 1.17～2.05, P<0.01; N％ OR=1.32, 95％ CI: 1.04～1.68, P<0.05; PLT OR=1.01, 95％ CI 1.00～1.01, P<0.01). Conclusion In case that abnormally high levels of PLT exist in confirmed Kawasaki disease, it should be aware of possibility of the intravenous immunoglobin-resistant Kawasaki disease.

Objective To understand the incidence and risk factors of warfarin related hemorrhagic events during anticoagulation therapy with warfarin in patients with cirrhosis and portal vein thrombosis (PVT)after transjugular intrahepatic portosystemic shunt (TIPS). Methods The patients with liver cirrhosis who were treated with warfarin after TIPS due to portal hypertension were followed up from January 2012 in Xijing Hospital of Digestive Diseases,Air Force Military Medical University. The data of medical records and follow-up records up to the end of December 2015 in patients undergoing TIPS were collected and retrospectively analyzed. Cumulative incidence of hemorrhagic events related to warfarin treatment was calculated by Kaplan-Meier method. The patients were divided into warfarin-related bleeding group (bleeding group ) and non warfarin-related bleeding group (non-bleeding group ). The risk factors of hemorrhagic events related to warfarin treatment were analyzed using Cox regression model and the hazard ratio (HR)and the 95% confidence interval (CI)were calculated. Results A total of 179 patients were enrolled,including 117 males and 62 females with ages of 25-79 years and average age of (52 ± 12)years;the bleeding group comprised 47 patients (26.3%)and the non-bleeding group comprised 132 patients (73.7%). The follow-up time after discharge ranged 1-74 months and the average time was (28 ± 21) months. The average portal pressure gradient dropped from (25.4 ± 5.2)to (8.7 ± 3.7)mmHg before and after TIPS (P＜0.001). The median dose of oral warfarin in patients in the bleeding group was 2.5 (ranged from 2.5 to 3.75)mg and the median INR was 3.12 (ranged from 2.04 to 9.41);the median dose of oral warfarin in patients in the non-bleeding group was 1.8 (ranged from 0.63 to 2.5)mg and the median INR was 1.85 (ranged from 1.5 to 3.38). Fifty eight cases of hemorrhagic events occurred in 47 patients in the bleeding group,including 24 cases of gingival bleeding,16 cases of epistaxis,8 cases of cutaneous purpura, 4 cases of conjunctival hemorrhage,2 cases of hemorrhage of digestive tract,2 cases of intracranial hemorrhage,1 cases of hematuria,and 1 cases of menorrhagia. Nine of the 47 patients in the bleeding group had bleeding from multiple sites. The results of Kaplan-Meier analysis showed that the 1-,2-,3-,4-,5-and 6-year cumulative incidences of hemorrhagic events related to warfarin treatment after operation were 19%,23%,24%,30%,41%,and 45%,respectively. Warfarin was stopped in 11 patients and given at reduced doses in 36 patients among the 47 patients in the bleeding group. After that,43 patients'hemorrhagic symptoms disappeared and 3 patients' symptoms relieved,and then warfarin treatments were continued,except that 1 patient with a long history of hypertension died of intracranial hemorrhage. Multiple Cox regression analysis showed that the baseline serum creatinine level ＞115 μmol/L was an independent risk factor for hemorrhagic events related to warfarin treatment (HR＝1.82,95%CI:1.01-3.28,P＝0.045). Conclusions It is relatively safe for patients with liver cirrhosis and PVT receiving warfarin anticoagulation therapy after TIPS. Elevated serum creatinine is an independent risk factor for hemorrhagic events related to warfarin treatment.
