Objective To explore the clinical effects of laparoscopic surgery combined with marvelon,gestrinone and leuprolide in treatment of chronic endometriosis.Methods 50 cases of endometriosis were collected.They were randomly divided into observation group and control group,each group having 25 cases.The control group underwent laparoscopic surgery and the observation group underwent laparoscopic surgery combined marvelon,gestrinone and leuprolide for 3 months.The two groups were compared in clinical effects,recurrence and pregnancy rate,as well as the operation situation.Results The effective rate was 92.0％ (23/25) in the observation group and 64.0％ (16/25) in the control group.The effective rate of observation group was obviously higher than that of the control group(P ＜ 0.05).The recurrence rate was 8.0％ (2/25)in the observation group,and 32.0％ (8/25) in the control group.The recurrence rate of combination group was obviously lower than that of the simple surgical group(P ＜ 0.05).The pregnancy rate was 80.0％ in the observation group;and 48.0％ in the control group after treatment.The pregnancy rate of the observation group was obviously higher than that of the control group(P ＜ 0.05).Liver damage or other adverse reactions didn't occur to any group after the treatment.The mean time of leaving bed was (1.4 ± 0.4) d after operation in the observation group vs (3.6 ± 1.5) d after operation in the control group.Length of hospital stay was (7.6 ± 3.5) d in the observation group vs (11.5 ± 3.9) d in the control group.The difference had statistical significance(all P ＜ 0.05).Conclusions Laparoscopic surgery combined with marvelon,gestrinone and leuprolide is superior to pure surgery group in treatment of endometriosis.It can improve the effective and pregnancy rate,and reduce the recurrence rate.No obvious adverse reactions can be found,thus it is worth of clinical promotion.

Protein kinases are intimately involved in the pathogenesis of many diseases such as cancer, inflammation, and autoimmune and neurological diseases. Therefore, kinases have been widely studied as drug targets over the past three decades. As of April, 2020, the FDA had approved 59 small molecule kinase inhibitors (SMKIs) in the emerging field of targeted drug therapy. This paper focuses on the biochemistry and pharmacology of these 59 SMKIs and 121 SMKIs for which structures can be retrieved and that are now in phase Ⅱ and Ⅲ clinical trials. In addition, this paper also conducts a simple analysis of several popular targets and their inhibitors.

Stress cardiomyopathy is an atypical myocardial disease induced by emotional or physical stress, with the characteristic of left ventricular systolic dysfunction, transient imaging and electrocardiogram (ECG) changes. Sudden cardiac death can occur in severe cases. Clinical symptoms are likely to appear on acute myocardial infarction, but the exact pathological mechanism is unclear. In the present study, we perform a systematic review of the literature on the clinical manifestations, epidemiological characteristics, ECG, imaging and laboratory tests of stress cardiomyopathy, in order to provide the values for forensic pathology diagnosis.

OBJECTIVETo investigate the roles of microRNA-21 (miR-21) in the pathogenesis of non-alcoholic fatty liver disease (NAFLD) with high-fat diet-induced insulin resistance (IR) and diabetes mellitus (DM) mice model.

METHODSEight-week-old C57BL/6 mice were allocated into control group, IR group, and DM group. Body mass was recorded. Intraperitoneal glucose tolerance test was performed to determine any abnormal glucose metabolism. The liver pathological changes were detected by biopsy. Changes in free blood glucose, free serum insulin, blood fat and tumor necrosis factor Α level were measured. Differences in miR-21 expression and peroxidase proliferator-activated receptor subtypes (PPAR-Γ and PPAR-Α) and adipocyte fatty acid binding protein (aP2) in the liver were detected both at the mRNA and protein levels.

RESULTSAfter one 8-week high-fat diet, the body mass, free serum insulin, and homeostasis model IR index significantly increased in the IR group (P<0.01, P<0.05, compared with control group), while the free blood glucose increased and the free serum insulin decreased in DM group (P<0.05). Free serum insulin level were significantly increased in IR group (P<0.05). Serum tumor necrosis factor-Α levels exhibited an upward trend in control group, IR group, and DM group (P<0.05, P<0.01). With exacerbation in NAFLD, liver miR-21 expression level went further down in both IR and DM groups (P<0.05). The downregulated miR-21 expression level showed negative correlation with upregulated PPAR-Α, ΑP2, and PPAR-Γ genetic expression (r=-0.696, r=-0.664, and r=-0.766, respectively; P<0.05) in IR group and with upregulated PPAR-Α and PPAR-Γ genetic expression in DM group (r=-0.676 and r=-0.550, respectively; P<0.05). In terms of the changes in protein expression level,only on the protein expressions of aP2 and PPAR-Γ in IR group showed significant change (P<0.05, P<0.01, compared with control group).

CONCLUSIONSThe miR-21 expression is downregulated in both IR and DM-induced NAFLD mice. It may be involved in the pathogenesis of NAFLD by regulating the expressions of PPAR subtypes.

Objective To learn the effects of control measures,the screening situation and the epidemic situation of Schistosomiasis in Yongsheng county of Lijiang city of Yunnan province,and to provide a scientific basis for developing control strategies.Methods Annual surveillance data of Schistosomiasis of Yongsheng county from 2002 to 2010 were collected and analyzed by material retrospective method.Schistosomiasis screening situation,infection rate of people and cattle as well as snails area was statistically analyzed.Infection rate of people was from the screening results by indirect hemagglutination(IHA),and pathogenic examination of the positives(1 ∶ 10)was carried out through collection of eggs with nylon bag and hatching the stool.Infection rate of cattle was from etiology examination results by plastic cup pipe jacking method.Results From 2002 to 2010,257679 individuals were screened and 26540 cases (10.30％) were seropositive; with stool examination,451 (1.72％) were identified positive of 26233 persons; 603 (0.71％) were found positive of 85658 oxen.All of the positive detection rate of IHA method,the feces-positive detection rate in the population and the prevalence rate of oxen showed a declining trend(x2 =3615.53,785.68,434.50,all P＜ 0.05).The snails area was gradually reduced,the rate of snails environmental area was decline from 23.82％ in 2004 to 1.98％ in 2010.Conclusions The endemic situation of Schistosomiasis in Yongsheng county is controlled in the past eight years,but remains epidemic,and we will continue to strengthen monitoring,in order to achieve the goal of blocking the spread of Schistosomiasis.

Objective Neonatal lupus erythematosus (NLE) is an uncommon" passive autoimmune disease, which is associated with transplacental passage of maternal antibodies. It is often misdiagnosed as intrauterine infection or sepsis. The main purpose of this retrospective study was to summarize its clinical manifestations related with pathogenesis.Methods Data of all the NLE neonates, including clinical manifestations, immunochemical evidence of serum antinuclear antibodies (ANA), antibody to Ro/Sjogren's syndrome A ( anti-Ro/SSA), antibody to La/Sjogren' s syndrome B (anti-La/SSB) and anti-dsDNA antibodies in both infants and mothers, and images from head ultrasound and CT scans were analyzed. Follow-up was performed until one and half years of age or when all the clinical abnormalities had been resolved.Results Totally 8 cases (3 males and 5 females ) seen between September 2003 and February 2006 met the diagnostic criteria of NLE, in whom 4 were small for gestational age and one was born prematurely. Mean gestational age was (38.1 ± 1.9 ) weeks, mean birth weight (2605 ± 420) g, mean admission age (22.4 ± 27.7 ) days (2 hours-72 days) and mean age of onset (9.4 ± 12. 1)days (0-28 days). The common clinical manifestations included cutaneous lupus lesions (8 infants ), neural system abnormalities (2 infants ) and congenital heart block (2 infants). Annular, erythematous or desquamative lesions were seen in skin and all disappeared before 6 months of age. One patient presented with third degree atrio-ventricular block and was delivered by cesarean section because of " fetal distress" He did not recover by the end of one and half years follow-up. One infant was hypotonic with delayed neuro-motor development initially and during follow-up with both abnormal neonatal behavioral neurological assessment (NBNA) and imaging findings. Brain CT scan showed generalized low density involving periventricular and deep white matter at one week of age. At the age of one and a half years, he presented with normal mental development index determined by Child Development Center of China (CDCC) infant intelligence mensuration. Other abnormal clinical findings such as hepatosplenomegaly, anemia, thrombocytopenia, cholestasis and elevated liver enzyme activities were all resolved before 6 months of age. Only 3 mothers of the NLE infants were diagnosed as systemic lupus erythematosus (SLE) before parturition and only one received partial therapy. At least anti-Ro/SSA antibody or anti-La/SSB antibody or ANA was found in the affected patients. Seven cases had circulating anti-Ro and/or anti-La antibodies in the mothers and in the newborns, while ANA was positive in seven newborns and in all mothers. All the clinical symptoms disappeared before 18 months ot age except for congenital heart block. No special intervention was applied.Conclusions Serum auto-antibodies should be investigated to rule out NLE when a newborn infant has congenital heart block or rashes or thrombocytopenia, although there is no maternal history of SLE. Central nervous system abnormalities in NLE are likely to be a transient phenomenon and whether it will cause long-term sequelae is uncertain.

OBJECTIVEConditioned taste preference (CTP) is a taste learning reflex by which an animal learns to prefer a substance which tastes not well and has been studied with much interest in recent years. However, the neural substrates of CTP are less known. This study aimed to determine the possible neural path- ways of CTP and whether serum leptin level and the leptin receptor (OB-Rb) in the hind brain are involved following CTP formation.

METHODSWe established CTP of quinine in rats with a 2-bottle preference test. The serum leptin concentrations were detected, the expression of c-fos in the rat brain was tested to determine the nuclei in relation with establishment of CTR Finally, the OB-Rb mRNA expression was examined by RT-qPCR assay in parabrachial nucleus (PBN) and the nucleus of the solitary tract (NST) of the hind brain.

RESULTSCompared with control group, the level of serum leptin was higher in the CTP group (4.58 ± 0.52 vs 1.67 ± 0.25 µg/L, P < 0.01); increased c-fos positive cells were found in the anterior hypothalamus (AH, 221.75 ± 4.96 vs. 178.50 ± 6.63 cells/mm², P < 0.05), the basal lateral amygdala (BLA, 70.75 ± 6.17 vs 56.50 ± 3.62 cells/ mm², P < 0.05) and the nucleus of the solitary tract (NST, 41.25 ± 1.32 vs 32.50 ± 1.02 cells/mm², P < 0.05). But in ventromedial nucleus of the hypothalamus (VMH, 20.75 ± 2.73 vs 38.5 ± 1.54 per 1 mm², P < 005), PBN (21.50 ± 2.24 vs 36.25 ± 1.49 cells/mm², P < 0.05) and the central nucleus of the amygdala (CeA, 22.25 ± 1.53 vs 35.50 ± 2.11 cells/mm², P < 0.05), the number of c-fos positive cells was decreased in the CTP group. In addition, we found OB-Rb mRNA expression in PBN of CTP group rats was higher than that of control group (0.95 ± 0.055 vs 0.57 ± 0.034, P < 0.05), while there was no significant difference of OB-Rb mRNA expression in NST between the two groups.

CONCLUSIONNuclei AH, BLA, NST, VMH, PBN and CeA participate in the formation of CTP. Leptin and its receptor in PBN may be involved in the formation and maintenance of CTP.

Objective To observe the therapeutic effect of Taoshi Jiangu Decoction for osteoporosis(OP). Methods A total of 120 cases of OP patients were randomly divided into treatment group and control group ,60 cases in each group. Patients in the treatment group were treated with Taoshi Jiangu Decoction orally,and those in the control group were treated with Caltrate D and Alendronate Sodium Tablets orally. Four weeks constituted one treatment course, and the treatment for the two groups covered 3 courses. The therapeutic effect of the two groups was evaluated by the changes of traditional Chinese medicine(TCM)syndrome scores,urine hydroxyproline (U-HYP),serum bone Gla-protein (BGP or osteocalcin),serum alkaline phosphatase (ALP),urine calcium (U-Ca),tartrate resistant acid phosphatase (TRAP), bone mass density(BMD) and quantitative CT(QCT) before and after treatment. Results (1)After treatment, the TCM syndrome scores of the two groups were decreased(P<0.05 compared with those before treatment),and the decrease in the treatment group was superior to that of the control group (P < 0.05). (2)After treatment,the levels of bone formation indexes of ALP and BGP were increased,and the levels of bone resorption indexes of U-HYP,U-Ca and TRAP were decreased in the two groups (P<0.05 compared with those before treatment). The effects of the treatment group were superior to those of the control group,the difference being statistically significant(P < 0.05).(3)After treatment,BMD of lumbar vertebrae 2-4 (L2-L4),neck of femur,Wards triangle and trochanter of femur,and QCT values of left neck of femur were obviously increased in the two groups (P < 0.05 compared with those before treatment). The treatment group showed stronger effect on increasing BMD and QCT values than the control group, the difference being statistically significant (P < 0.05). Conclusion Taoshi Jiangu Decoction can restrain bone absorption , promote bone formation and increase BMD, showing certain therapeutic effect for OP.
