Previous studies have shown that high blood glucose-induced chronic microinflammation can cause inflammatory podocyte injury in patients with diabetic kidney disease(DKD). Therein, necroptosis is a new form of podocyte death that is closely associated with renal fibrosis(RF). To explore the effects and mechanisms in vivo of total flavones of Abelmoschus manihot(TFA), an extract from traditional Chinese herbal medicine Abelmoschus manihot for treating kidney diseases, on podocyte necroptosis and RF in DKD, and to further reveal its scientific connotation with multi-pathway and multi-target, the authors randomly divided all rats into four groups: a namely normal group, a model group, a TFA group and a rapamycin(RAP) group. After the modified DKD rat models were successfully established, four group rats were given double-distilled water, TFA suspension and RAP suspension, respectively by gavage every day. At the end of the 4th week of drug treatment, all rats were sacrificed, and the samples of their urine, blood and kidneys were collected. And then, the various indicators related to podocyte necroptosis and RF in the DKD model rats were observed, detected and analyzed, respectively. The results indicated that, general condition, body weight(BW), serum creatinine(Scr), urinary albumin(UAlb), and kidney hypertrophy index(KHI) in these modified DKD model rats were both improved by TFA and RAP. Indicators of RF, including glomerular histomorphological characteristics, fibronectin(FN) and collagen type Ⅰ(collagen Ⅰ) staining extent in glomeruli, as well as the protein expression levels of FN, collagen Ⅰ, transforming growth factor-β1(TGF-β1) and Smad2/3 in the kidneys were improved respectively by TFA and RAP. Podocyte damage, including foot process form and the protein expression levels of podocin and CD2AP in the kidneys was improved by TFA and RAP. In addition, tumor necrosis factor-α(TNF-α)-mediated podocyte necroptosis in the kidneys, including the morphological characteristics of podocyte necroptosis, the extent and levels of the protein expression of TNF-α and phosphorylated mixed lineage kinase domain like pseudokinase(p-MLKL) was improved respectively by TFA and RAP. Among them, RAP had the better effect on p-MLKL. More importantly, the activation of the receptor interacting serine/threonine protein kinase 1(RIPK1)/RIPK3/MLKL signaling axis in the kidneys, including the expression levels of its key signaling molecules, such as phosphorylated receptor interacting serine/threonine protein kinase 1(p-RIPK1), p-RIPK3, p-MLKL and cysteinyl aspartate specific proteinase-8(caspase-8) was improved respectively by TFA and RAP. Among them, the effect of TFA on p-RIPK1 was superior. On the whole, in this study, the authors demonstrated that TFA alleviates podocyte necroptosis and RF in DKD through inhibiting the activation of the TNF-α-mediated RIPK1/RIPK3/MLKL signaling axis in diabetic kidneys. The authors' findings provide new pharmacological evidence to reveal the scientific connotation of TFA in treating RF in DKD in more depth.

A comprehensive analytical method based on ultra-fast liquid chromatography coupled with triple quadrupole/linear ion trap tandem mass spectrometry(UFLC-QTRAP-MS/MS) was established for simultaneous determination of the content of 38 active components in Abelmoschi Corolla, including flavonoids, organic acids, nucleosides and amino acids, so as to investigate the effects of different harvesting and processing methods on multi-active components in Abelmoschi Corolla. The chromatographic separation was performed on a XBridg®C_(18) column(4.6 mm×100 mm, 3.5 μm) with(0.1% formic acid water) methanol-acetonitrile(1∶1) as the mobile phase for gradient elution at 30 ℃. The flow rate was 0.5 mL·min~(-1). The components were detected in a multiple-reaction monitoring(MRM) mode. The gray relational analysis(GRA) was used to comprehensively evaluate the multiple active components of Abelmoschi Corolla at different harvesting times and drying temperatures. The results showed that 38 components had a good linearity with correlation coefficients all above 0.999 0. The method featured a good precision, repeatability and stability with the relative stan-dard deviations(RSDs) of less than 5.0%. Recoveries ranged from 98.06% to 104.4% with RSD between 0.22% and 4.9%. The results of GRA indicated that a better quality in the samples collected on September 9 th. Samples dried at 90 ℃ had a better quality. The established method is accurate and reliable, and can be used to assess the internal quality of Abelmoschi Corolla. This study can provide basic materials for determining appropriate harvesting time and processing method of Abelmoschi Corolla.

OBJECTIVETo compare the clinical effect of Chinese medicine (CM) and Western medicine (WM) for controlling the recurrence of pelvic endometriosis after a conservative operation.

METHODSThe study was a multi-center, randomized, parallel controlled and prospective clinical trial. Patients were randomly divided into two groups: CM group (106 cases) and WM group (102 cases). Drugs were given to patients during 1-5 days of the first menstruation after a conservative operation in both groups. Patients with stages I and II (revised American Fertility Society) were treated for 3 months, while the patients with stages III and IV were treated for 6 months. The patients in the CM group were treated using three types of Chinese herbal medicine based on syndrome differentiation. Patients in the WM group were treated using gonadotropin releasing hormone agonist (GnRH-a) or gestrinone. Patients treated with GnRH-a received add-back therapy of Tibolone Tablets once a day after 4 months of treatment. Any cases of dysmenorrheal chronic pelvic pain, menstruation and any adverse reactions of patients were recorded once a month during the preoperative and postoperative periods and once every 3 months during the follow-up period. During the preoperative, postoperative and the follow-up periods, patients underwent type B ultrasonography of the pelvis and measurements of serum CA125 levels, gynecologic examination, routine evaluations of blood, urine, hepatic function (glutamate pyruvate transaminase), renal function (blood urea nitrogen) and electrocardiograms. During the follow-up period they underwent type B pelvic ultrasonography, measurement of serum CA125 levels and further gynecologic examinations. The two treatments were compared for clinical recurrence rates, pregnancy rates and the incidence of adverse reactions.

RESULTSThe incidence and timing of recurrence of endometriosis were not significantly different between the two groups. The first pregnancy achieved by the patient in the CM group was significantly earlier than that in the WM group (P <0.05). Moreover, the incidence of adverse reactions in the WM group was significantly higher than in the CM group (P <0.01).

CONCLUSIONSTreatment with Chinese herbal medicines prevented the recurrence of endometriosis after a conservative operation, improved the conception rate and showed fewer and lighter adverse reactions than did treatment with WM therapy. Treatment with Chinese herbal medicine meets the need of patients wishing to have a child following endometriosis and is an appropriate form of clinical treatment.

OBJECTIVETo elucidate the clinical features, response rate, prognosis and clonal evolution of aplastic anemia (AA) with macrocytic anemia (mAA).

METHODSThe clinical features at initial diagnosis and data in follow up of mAA hospitalized from January 2000 to October 2011 were analyzed retrospectively.

RESULTS(1) Of 153/568 (26.9%) cases of mAA at initial diagnosis, 114(74.5%)were non-severe AA (NSAA), 39(25.5%)severe AA (SAA) and 0 very severe AA (VSAA), while the proportion was 16.2%, 45.2%, and 38.6% in 376 normocytic anemia AA (nAA), and the difference is statistically significant(χ(2) = 181.390; P = 0.000). The median age of mAA was significantly higher than that of nAA \[30(4 - 70)years vs 19 (3 - 68) years, P = 0.001\]. (2) There were no statistical difference in hemoglobin, absolute neutrophil count (ANC), platelet count (PLT), response rate after 6 months treatment and overall survival (OS) between mAA and nAA grouped in SAA and NSAA respectively. In SAA, the reticulocyte count (Ret) of mAA was significantly higher than that of nAA \[23.90(2.99 - 61.00)×10(9)/L vs 13.1(0 - 70.60)×10(9)/L, P = 0.000\] and the proportion of erythroid cells in bone marrow of mAA was also higher \[23.5 (0 - 58) vs 14.5 (0 - 65), P = 0.043\], while they did not differ significantly in NSAA. (3) The proportion of AA with PNH clones or abnormal cytogenetics did not differ significantly in mAA and nAA groups before treatment. The incidences of AA evolved to PNH in mAA and nAA was not statistically significant (7/153 vs 9/376, χ(2) = 1.099, P = 0.294) and so was the incidence of evolution to MDS/AML(3/153 vs 13/376, χ(2) = 0.399, P = 0.528).

CONCLUSIONIn presented with macrocytic anemia at initial diagnosis of AA, higher proportion of NSAA, elderly age, higher Ret and proportion of erythroid cells are features, but being no statistical difference in the response rate, OS, and proportion of clonal evolution.

OBJECTIVETo explore the clinical effects of combined medial and lateral malleolus in treating severe fracture of ankle.

METHODSFrom May 2007 to January 2011,89 patients with ankle fracture who underment surgical treatment and had complete follow-up, the data were retrospectively analyzed. In this study, there were 66 males and 23 females with an average age of 30.9 years (ranged, 26 to 62 years). Cause of injury included road accidents in 52 cases,sprains from fall down in 17, construction injury in 16 and other injuries in 4. According to type of Denis-Weber, type A were in 13 cases, type B in 24, type C in 52. Operative technique was as follows. Chosen two-incision of combined medial and lateral malleolus, and reduced lateral malleolus fracture firstly, fixed it with 1/3 tubular armor plate or rebuilt-titanium plate. To chose one or two hollow screws according to the size of fracture block. If fracture of fibula was syntripsis,it can be multi-segmental fixed. If fracture line of posterior malleolus was no more than 1/3 articular surface of ankle or the bone displacement was not serious, it can be disregarded. And if the lesion level was over 1/3, or shift position more than 3 mm,it can be fixed with lag screw after reduction. Either front-to-back or back-to-front fixed direction was OK. At the third day after operation, the patients were instructed to exercise with affected limb, weight training after 6 weeks.

RESULTSEighty-nine patients were followed up from 6 to 24 months with an average of 16 months. Healing time of the fracture was 10 to 12 months. According to standard of the Baird-Jackson scoring system, 68 cases got excellent results, 18 good and 3 fair.

CONCLUSIONSurgical treatment is quite effective for severe fracture of ankle. It should be chosen correctly according to types of the fracture and degree of ligament injury. At the same time, damage degree of the ligament around the ankle should be considered and properly treated.
