ABSTRACT

Objective: To compare the effects and safety of dydrogesterone (DG) and medroxyprogesterone acetate (MPA) on the treatment in patients with endometrial hyperplasia without atypia (EH). Methods: This was a single-center, open-label, prospective non-inferior randomized controlled phase Ⅲ trial. From February 2019 to November 2021, patients with EH admitted to the Obstetrics and Gynecology Hospital of Fudan University were recruited. Enrolled patients were stratified according to the pathological types of simple hyperplasia (SH) or complex hyperplasia (CH), and were randomised to receive MPA or DG. Untill May 14, 2022, the median follow-up time after complete response (CR) was 9.3 months (1.1-17.2 months). The primary endpoint was the 6-month CR rate (6m-CR rate). The secondary endpoints included the 3-month CR rate (3m-CR rate), adverse events rate, recurrence rate, and pregnancy rate in one year after CR. Results: (1) A total of 292 patients with EH were enrolled in the study with the median age of 39 years (31-45 years). A total of 135 SH patients were randomly assigned to MPA group (n=67) and DG group (n=68), and 157 CH patients were randomly assigned to MPA group (n=79) and DG group (n=78). (2) Among 292 patients, 205 patients enrolled into the primary endpoint analysis, including 92 SH patients and 113 CH patients, with 100 patients in MPA group and 105 in DG group, respectively. The 6m-CR rate of MPA group and DG group were 90.0% (90/100) and 88.6% (93/105) respectively, and there were no statistical significance (χ2=0.11, P=0.741), with the rate difference (RD) was -1.4% (95%CI:-9.9%-7.0%). Stratified by the pathology types, the 6m-CR rate of SH patients was 93.5% (86/92), and MPA group and DG group were respectively 91.1% (41/45) and 95.7% (45/47); and the 6m-CR rate of CH patients was 85.8% (97/113), and MPA group and DG group were 89.1% (49/55) and 82.8% (48/58) respectively. The 6m-CR rates of the two treatments had no statistical significance either (all P>0.05). A total of 194 EH patients enrolled into the secondary endpoint analysis, including 88 SH patients and 106 CH patients, and 96 patients in MPA group and 98 in DG group, respectively. The 3m-CR rate of SH patients were 87.5% (77/88), while the 3m-CR rates of MPA group and DG group were 90.7% (39/43) and 84.4% (38/45), respectively; the 3m-CR rate of CH patients was 66.0% (70/106), and MPA group and DG group had the same 3m-CR rate of 66.0% (35/53). No statistical significance was found between the two treatments both in SH and CH patients (all P>0.05). (3) The incidence of adverse events between MPA group and DG group had no statistical significance (P>0.05). (4) A total of 93 SH patients achieved CR, and the cumulative recurrence rate in one year after CR were 5.9% and 0 in MPA group and DG group, respectively. While 112 CH patients achieved CR, and the cumulative recurrence rate in one year after CR were 8.8% and 6.5% in MPA group and DG group, respectively. There were no statistical significance between two treatment groups (all P>0.05). Among the 93 SH patients, 10 patients had family planning but no pregnancy happened during the follow-up period. Among the 112 CH patients, 21 were actively preparing for pregnancy, and the pregnancy rate and live-birth rate in one year after CR in MPA group were 7/9 and 2/7, while in DG group were respectively 4/12 and 2/4, and there were no statistical significance in pregnancy rate and live-birth rate between the two treatment groups (all P>0.05). Conclusions: Compared with MPA, DG is of good efficacy and safety in treating EH. DG is a favorable alternative treatment for EH patients.

ABSTRACT

The quality of moxa is an important factor affecting moxibustion therapy, and traditionally, 3-year moxa is considered optimal, although scientific data are lacking. This study focused on 1-year and 3-year moxa from Artemisia stolonifera and A. argyi(leaf-to-moxa ratio of 10∶1) as research objects. Scanning electron microscopy(SEM), Van Soest method, and simultaneous thermal analysis were used to investigate the differences in the combustion heat quality of 1-year and 3-year moxa and their influencing factors. The results showed that the combustion of A. stolonifera moxa exhibited a balanced heat release pattern. The 3-year moxa released a concentrated heat of 9 998.84 mJ·mg~(-1)(accounting for 54% of the total heat release) in the temperature range of 140-302 ℃, with a heat production efficiency of 122 mW·mg~(-1). It further released 7 512.51 mJ·mg~(-1)(accounting for 41% of the total heat release) in the temperature range of 302-519 ℃. The combustion of A. argyi moxa showed a rapid heat release pattern. The 3-year moxa released a heat of 16 695.28 mJ·mg~(-1)(accounting for 70% of the total heat release) in the temperature range of 140-311 ℃, with an instantaneous power output of 218 mW·mg~(-1). It further released 5 996.95 mJ·mg~(-1)(accounting for 25% of the total heat release) in the temperature range of 311-483 ℃. Combustion parameters such as-R_p,-R_v, D_i, C, and D_b indicated that the combustion heat quality of 3-year moxa was superior to that of 1-year moxa. It exhibited greater combustion heat, heat production efficiency, flammability, mild and sustained burning, and higher instantaneous combustion efficiency. This study utilized scientific data to demonstrate that A. stolonifera could be used as excellent moxa, and the quality of 3-year moxa surpassed that of 1-year moxa. The research results provide a scientific basis for the in-depth development of A. stolonifera moxa and the improvement of moxa quality standards.

ABSTRACT

The quality of moxa is a key factor affecting the efficacy of moxibustion. Traditional moxa grades are evaluated by the leaf-to-moxa ratio, but there is a lack of support from scientific data. Scanning electron microscopy(SEM), Image Pro Plus, Van Soest method, and stimultaneous thermal analysis(TGA/DSC) were used to characterize the scientific implication of the combustion differences between moxa with different leaf-to-moxa ratios(processed by crusher). The results showed that the median lengths from non-secretory trichomes(NSTs) of natural NSTs and moxa with leaf-to-moxa ratios of 3∶1, 5∶1, 10∶1, and 15∶1 were 542.46, 303.24, 291.18, 220.69, and 170.61 μm, respectively. The cellulose content of moxa increased significantly(P<0.05) with the increase in leaf-to-moxa ratio and the combustion parameters(T_i, t_i, D_i, C,-R_p,-R_v, S, D_b, and J_(total)) all showed an increasing trend. The correlation results showed that the burning properties of moxa(T_i,-R_v, t_i, and J_2) were significantly and positively correlated with cellulose content. NSTs with a length of 1-200 μm were significantly and positively correlated with J_2. NSTs with a length of 200-600 μm were significantly and positively correlated with J_1, T_(peak2), T_(peak1), and-R_v, and negatively correlated with J_(total), T_b, and t_b. As the leaf-to-moxa ratio increases, the NSTs in the moxa become shorter and the cellulose content increases, which is more conducive to ignition performance, heat release, and a milder, longer-lasting burn. The "NSTs-cellulose-TGA/DSC" quantitative evaluation method scientifically reveals the scientific connotation of the combustion of moxa with different leaf-to-moxa ratios and provides a scientific basis for the establishment of quality evaluation methods for moxa with different leaf-to-moxa ratios.

ABSTRACT

In recent years, continuous manufacturing technology has attracted considerable attention in the pharmaceutical industry. This technology is highly sought after for its significant advantages in cost reduction, increased efficiency, and improved productivity, making it a growing trend in the future of the pharmaceutical industry. Compared to traditional batch production methods, continuous manufacturing technology features real-time control and environmentally friendly intelligence, enabling pharmaceutical companies to produce drugs more efficiently. However, the adoption of continuous manufacturing technology has been slow in the field of traditional Chinese medicine(TCM) pharmaceuticals. On the one hand, there is insufficient research on continuous manufacturing equipment and technology that align with the characteristics of TCM preparations. On the other hand, the scarcity of talent with diverse expertise hampers its development. Therefore, in order to promote the modernization and upgrading of the TCM pharmaceutical industry, this article combined the current development status of the TCM industry to outline the development status and regulatory requirements of continuous manufacturing technology. At the same time, it analyzed the problems with existing TCM manufacturing models and explored the prospects and challenges of applying continuous manufacturing technology in the field of TCM pharmaceuticals. The analysis focused on continuous manufacturing control strategies, technical tools, and pharmaceutical equipment, aiming to provide targeted recommendations to drive the development of the TCM pharmaceutical industry.

ABSTRACT

The present study explored the drying effect of new spiral vibration drying technology on Chinese medicinal pills with Liuwei Dihuang Pills, Zhuanggu Guanjie Pills, and Muxiang Shunqi Pills as model drugs. With the drying uniformity, drying time, energy consumption, pill split, dissolution time, and change of index components as evaluation indicators, the drying effect of spiral vibration drying technology on model drugs was evaluated and compared with traditional drying methods, such as hot air drying and vacuum drying in the oven. The dynamic changes of moisture in Liuwei Dihuang Pills with different drying time were investigated. Compared with the traditional drying methods in the oven(hot air drying and vacuum drying) at 80 ℃, the spiral vibration drying only took 80 min, shortened by 80%, with 10%-13% energy consumed. The results showed that the moisture of Liuwei Dihuang Pills was negatively related to the drying time. By virtue of multi-layer countercurrent drying and super resonant fluidization techniques, the new spiral vibration drying technology can significantly improve the drying quality of Chinese medicinal pills, improve the drying efficiency, and enhance the manufacturing capacity of Chinese medicinal pills. This study is expected to provide references for the innovation and development of new drying technology of Chinese medicinal pills.

ABSTRACT

At present,the production equipment and process of Chinese patent medicines still have many problems including high energy consumption,low efficiency,high pollution,and low intelligence,which seriously hinder the transformation,upgrading and modernized development of traditional Chinese medicine industry. With the emergence of various new pharmaceutical technologies and the application of technologies of other fields in traditional Chinese medicine industry,the development of Chinese patent medicine has ushered in new opportunities. The processes such as pulverization,mixing,extraction,separation,concentration,drying and sterilization are unique for the production of Chinese patent medicine. These main features can be distinguished from the manufacturing process of chemical drugs,determining the characteristics of the production process and equipment of Chinese patent medicine. In this paper,each operation unit was mentioned to summarize and analyze the new equipment and new technologies with advantages and characteristics in recent years from the perspectives of definition,principle,classification and application. Among them,the automatic spray device of the mixer,the extraction and separation equipment of volatile oil,and the crane basket-type circulation extraction technology,composite multi-layer spiral vibration countercurrent drying,and vibration sterilization equipment all have rapid development in recent years,with great prospects in the production of Chinese patent medicines. In this paper,we also analyzed some problems existing in the production equipment and technology of Chinese patent medicine and the key factors restricting the development of Chinese patent medicine,discussed the transformation of Chinese patent medicine production from traditional to modern and from semi-automatic to intelligent,and put forward three suggestions to help Chinese patent medicine achieve the goal of improving quality,efficiency and green manufacturing in production.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the role of allograft inflammatory factor-1 (AIF-1) in colorectal cancer (CRC) progression and explore the possible mechanism.</p><p><b>METHODS</b>The expression levels of AIF-1 in 70 CRC tissues and paired adjacent tissues were detected using immunohistochemistry and Western blotting, and the correlation of AIF-1 expression with the clinicopathological features of the patients was analyzed. In the CRC cell line SW480, the functional role of AIF-1 in regulating tumor progression was investigated by transfecting the cells with an AIF-1-overexpressing plasmid (AIF-1) and a negative control plasmid (NC). EdU proliferation assay and flow cytometry were used to assess the cell proliferation and cell cycle changes; Transwell migration assay and Annexin V-APC/7-AAD apoptosis assay kit were used to analyze the cell migration and apoptosis. The changes in the biological behaviors of the cells were observed after application of SB203580 to block the p38 MAPK pathway. The expression levels of CDK4, cyclin D1, P21, P27, MMP2, MMP9, Bax, Bcl2, Bcl-xl, p38 and p-p38 were detected using Western blotting.</p><p><b>RESULTS</b>AIF-1 was down-regulated in CRC tissues compared with the adjacent normal tissues, and its expression level was positively correlated with lymph node metastasis (P=0.008), TNM stage (P=0.003) and tumor size (P=0.023). Overexpression of AIF-1 in SW480 cells significantly reduced EdU-positive cells and caused obvious cell cycle arrest in G1 phase (P<0.05). AIF-1 overexpression resulted in significantly lowered protein expressions of CDK4 and cyclin D1, enhanced expressions of P21 and P27, attenuated cell migration ability (P<0.001), and decreased protein levels of MMP2 and MMP9. AIF-1 overexpression also induced obvious apoptosis of SW480 cells (P<0.01), significantly increased the protein levels of Bax and p-p38, and decreased the protein levels of Bcl-2 and Bcl-xl; SB203580 significantly attenuated the apoptosis-inducing effect of AIF-1 overexpression.</p><p><b>CONCLUSION</b>AIF-1 plays the role of a tumor suppressor in CRC by inhibiting cell proliferation, suppressing cell migration and inducing cell apoptosis. AIF-1 overexpression promotes the apoptosis of CRC cells by activating the p38 MAPK pathway.</p>

ABSTRACT

Objective Discuss the clinical efficacy by using two kinds of mini perforator free flap for digital injuries reconstruction. Methods From August, 2014 to February, 2017, 45 patients were managed randomly with either radial artery superficial palmar branch(RASPB)perforator free flap or digital artery(DA)perforator free flap for digital skin defects reconstruction, and they were therefore divided into two groups according to the flap type. There were 24 patients in RASPB group, with an average wound dimensions ranged from 1.8 cm×1.5 cm to 4.0 cm×2.5 cm, and an average harvested flap size ranged from 2.0 cm×1.7 cm to 4.2 cm×2.6 cm. Another 21 patients were in DA group, with an average wound dimensions ranged from 2.0 cm×1.5 cm to 3.8 cm×3.0 cm, and an average harvested flap size ranged from 2.2 cm×1.6 cm to 3.9 cm×3.2 cm. The survival rate, sensory function, donor site complications, hand function recovery and aesthetic outcomes of two groups were compared by the SPSS22.0 statistical software after surgery. Results The mean follow up period was 15 months. All flaps were primary survived without vascular crisis. The flaps were soft in texture,trimness in appearance and none of them overtop the normal skin for more than 0.5 cm. Both groups had a favorable sensory recovery.All cases recovery to S3+or better.In Group RASPB,the mean two point discrimination(2 PD)was 7.85±1.15 mm(ranged from 7.0 mm to 9.0 mm). And it was 6.02±0.94 mm(ranged from 6.0 mm to 8.0 mm)in DA group. The difference between two groups was statistically significant(P <0.05). Then we synthetically analyzed flap texture and sensory function,and calculated the qualified ratio of each group.There was no significant difference between two groups(P > 0.05). The degree of scar contracture demonstrated donor site compli cations in RASPB group was lesser than that in DA group(P<0.05).The range of motion of interphalangeal joint was used to reflect the hand function. And we calculated the ratio of repaired and contralateral sites. The difference of the mean ratio between two groups was not statistically significant(P>0.05). Conclusion On account of the characteristics of invariant anatomy position, sufficient blood supply, favorable aesthetic outcome and minimal donor site mobility, both RASPB perforator flap and DA perforator flap were optimal for digital skin defects reconstruction.Besides,incorporated with nerve and tendon,the RASPB perforator flap can also be used for complex tissue transplantation,and the surgery field was only on the arm.While the DA perforator free flap had an advantage of better sensory recovery and appearance.

The mean LVEDD of group A at 3 months after PCI was significantly larger than group B(52.3±4.8)mm vs.(48.6±5.1)mm,P=0.019,the mean LVEF of group A 3 months post PCI was lower than that of group B(48.6±7.3)% vs.(56.1±4.7)%,P=0.003.The mean increase in LVEDD at 3 months after PCI in group A was higher than group B(4.1±6.3)mm vs.(0.8±4.4)mm, p=0.005 and the mean increase in LVEF in group A was significantly lower than in group B(–1.9±6.8)% vs. (4.3±5.4)%,P=0.007. 3. HbA1chad positive correlation with LVEDD(r=0.324,p=0.048)and its increase at 3 months postoperatively(r=–0.422,P=0.005).4. Risk estimation found type 2 diabetes was an independent risk factor for poor recovery of LVEF. The MACE rate was signifi cantly higher in Group A than in Group B(35.7% vs.9.4%,P=0.018).Conclusions Patients with type2 diabetes were more prone to suffer from coronary microcirculatory dysfunction and had poor recovery of cardiac function. Poorly controlled type 2 diabetes was an independent risk factor for poor recovery of cardiac function and short-term prognosis was worse in diabetic patients who had elective PCI.

ABSTRACT

<p><b>OBJECTIVE</b>To analyze the treatment outcome of a consecutive series of 100 leukemia patients received allogeneic hematopoietic stem cell transplantation (allo-HSCT).</p><p><b>METHODS</b>The clinical data of leukemia patients received allo-HSCT were analyzed retrospectively, the therapeutic efficacy was summarized. 100 evaluable cases of leukemia included 47 cases of AML, 33 cases of ALL, 2 cases of AL (biphenotypic), 16 CML and 2 CMML. Before transplantation, 76 cases were in first complete remission, 9 cases in second or greater complete remission and 15 cases in non-remission or relapse. All the patients received peripheral blood hematopoietic stem cell transplantation (PBHSCT). The conditioning regimen of human leukocyte antigen (HLA)-matched allo-HSCT group was modified BuCy, but in HLA-mismatched group Fludarabine and anti-human thymocyte globulin (ATG) was added. CsA+MTX regimen was used for prophylaxis of graft-versus-host disease (GVHD) in HLA-identical allo-HSCT, while additional MMF was added in HLA-mismatched group. The average time of follow-up was 13 months.</p><p><b>RESULTS</b>At the last follow-up, 66.0% (66/100) patients survived, 53.0% (53/100) patients survived without leukemia, 28.0% (28/100) patients relapsed and 34.0% (34/100) patients died, 44.1% patients of them died from infectious pulmonary complications. During transplantation, 65.0% of the patients were suffered from lung infection. The overall survival (OS) and disease-free survival (DFS) of all cases was 60.9% and 48.8%, respectively. The recurrence rate was significantly higher in non-remission (66.7%) than in CR (21.2%) patients (P < 0.05). The cumulative incidence of GVHD in HLA-mismatched transplantation was 60.8%, which was significantly higher than that of HLA-matched transplantation (38.8%) (P < 0.05).</p><p><b>CONCLUSION</b>Allo-HSCT can cure a significant proportion of leukemia patients, especially for those in CR status. Since the incidence of infectious pulmonary complications after allo-HSCT is still high, much more attention should be paid to it. The comprehensive prognosis of HLA-matched transplantation is better than the HLA-mis-matched transplantation.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the efficacy and safety of sorafenib combined with low dose cytarabine for treating patients with FLT3(+) relapsed and refractory acute myeloid leukemia (FLT3(+) RR-AML).</p><p><b>METHODS</b>Seven patients with FLT3(+) RR-AML were treated with sorafenib and low dose cytarabine. The curative rate and adverse effects were observed in these patients.</p><p><b>RESULTS</b>Out of 7 RR-AML patients after treatment, 5 patients achieved complete remission (CR), 2 patients achieved partial remission (PR), and the overall response rate (ORR) after one course of therapy was 100%. No severe bleeding, nausea, vomiting and other side effects were found in these patients.</p><p><b>CONCLUSION</b>Sorafenib combined with low dose cytarabine can effectively induce the remission of FLT3(+) RR-AML patients, and is worth for further clinical trails to verify its safty and efficiency.</p>

ABSTRACT

OBJECTIVE: To screen small molecule metabolites of dibutyl phthalate( DBP) in the rat plasma using ~1H nuclear magnetic resonance( NMR) technology; and to clarify the changes of metabolites and possible mechanism in metabolic regulation of DBP in rats from the molecular level and the aspects of material and energy metabolism. METHODS: According to random number table method,twenty-four specific pathogen free SD male rats were divided into four groups: control group,low dose group,middle dose group and high dose group with the given dose of 0,500,1 000 and1 500 mg / kg of body mass,respectively. After giving DBP of gavage once a day for two weeks,the plasma samples were obtained,and ~1H NMR spectra was recorded. The plasma metabonomic profiles were analyzed using pattern recognition.Difference metabolites were screened by principal components analysis,partial least squares-discriminate analysis and orthogonal partial least squares-discriminate analysis. Biomarkers was screened by variable importance in the projection norm. RESULTS: There were changes of twelve important metabolites in the plasma metabonomic profiles between DBP treatment groups and control group. The differences of metabolites had dose-effect relationship. Plasma levels of high density lipoprotein cholesterol, low density lipoprotein cholesterol, hydrobutyrate, glycoprotein, citric acid, glucose,creatine phosphate,unsaturated fatty acid,tyrosine and phenylalanine were reduced( P < 0. 05),while lactic acid and pyruvic acid were increased( P < 0. 05). CONCLUSION: DBP induces the metabolic disorders including amino acid metabolism,lipid metabolism and energy metabolism.
