Objective To study the influence and the optimal dosages of Sijunzi Decoction (SJZD) on treating digestive and immune function of mice with Pi-deficiency syndrome (PDS). Methods The experimental model of mice with PDS was induced by rhubarb decoction. Then the mice were treated with three dosages of SJZD (12.5, 25, and 37.5 g/kg), respectively. The body weight, body temperature, mean retention time of chyme in digestive tract, gastric emptying velocity, gastrin and motilin levels, and visceral index of mice were measured. Results Being compared with the normal group, the PDS mice showed a slower growth of body weight and a lower body temperature, a shorter mean retention time of chyme in digestive tract and faster gastric emptying velocity, a lower gastrin content, and a higher motilin content. Also splenic and thymus indexes were found to follow a downtrend in the PDS mice. Three dosages of SJZD showed a restoration effect on the above all indexes, and the high dosage was the most effective one, especially. Conclusion The high dosage (37.5 g/kg) of SJZD possibly is the optimal dosage on treating the digestive and immune diseases of PDS mice.

Objective To observe the effects of different doses of Sijunzi decoction(SJZD) on soleus(SOL) atrophy in tail-suspended rats.Methods Weightlessness was simulated by tail suspension in female Sprague-Dawley rats.Six rats in each group were assigned to a 5-group design randomly: control(CON);hind limb unloading(HLU) plus intragastric water instillation(HLU-W),as well as plus intragastric high dose(HLU-H),middle dose(HLU-M) and low dose(HLU-L) SJZD instillation respectively.Immunohistochemical method was used to observe the effects of them on expression of myosin heavy chain(MHC) isoforms in soleus muscle.Results Compared with HLU-W,muscle wet weight(MWW) of SOL in high and middle dose group increased by 33.11%and 37.57%respectively,as well as no significant difference with CON;three doses of SJZD groups increased the percentage of type Ⅰ myosin by 34.04%~54.90% and its cross sectional area(CSA) by 8.50%~36.86%,moreover SJZD of middle dose group showed no significant difference with that of CON group.Conclusion Three doses of SJZD groups can significantly prevent soleus atrophy induced by simulated weightlessness,and middle dose is the more effective one than high and low dose.

Objective To study the effects of choline chloride on activities of myosin adenosine triphosphatase (mATPase) of muscle fibres and muscle atrophy in tail-suspended rats. Method Twenty-four adult female Sprague-dawley rats were averagely divided into 3 groups matched for body mass:control group(CON),tail suspension group(TS) and tail suspension group associated with choline chloride(TS+Cch).Weightlessness was simulated by 14 d tail suspension of rats;gastric lavage with choline chloride was given to 1/2 of the rats during tail suspension (15 mg/kg body weight.i.g.).Activities of myosin adenosine triphosphatase (mATpase) of intrafusal and extrafusal fibres in soleus (SOL) muscle were determined by Ca 2+-ATPase method.Paraffin sections of the soleus muscle were prepared by routine histochemistry method. Result After tail suspension for 14 d it was found: 1) percentage of type Ⅱ fibre in SOL of rats treated with choline chloride decreased distinctly as compared with that in the untreated rats (P

AIM To study the therapeutic effects of Deketoprofen trometamol (D KPT) on adjuvant arthritis (AA) and its side effects on gastroduodena. METHEDS The change of primary and secondary inflammatory and the injury effect of gastroduodena treated with D KPT were observed. The effect of D KPT on prostaglandin E 2 (PGE 2) produced by peritoneal macrophage (PM) on AA rats in vitro was also observed. RESULTS D KPT (2 5, 5, 10 mg?kg -1 ) significantly inhibited primary inflammatory, secondary inflammatory and multiple arthritis of AA rats. D KPT(10 -8 ,10 -7 ,10 -6 ,10 -5 ,10 -4 mol?L -1 )inhibited the elevated PGE 2 released from PM of AA rats in vitro . D KPT (10 mg?kg -1 ) significantly injured gastroduodena on AA rats, but the degree of injuries was less than that of ketoprofen (KP) (10 mg?kg -1 ). CONCLUSION D KPT has therapeutic effects on AA rats, and its injury effect on gastroduodena is less than that of KP.

Objective : To analyze the trends in incidence of thyroid cancer in Huangpu District, Shanghai from 2002 to 2017, so as to provide insights into the management of thyroid cancer. Methods : The incidence of thyroid cancer in Shanghai from 2002 to 2017 was collected from the cancer registration system created by Shanghai Center for Disease Control and Prevention. The crude and standardized incidence of thyroid cancer were estimated by year, gender and age groups, and annual change percentage ( APC ) was calculated to analyze the trends in incidence of thyroid cancer. Results : A total of 2 854 new cases of thyroid cancer were reported in Huangpu District from 2002 to 2017, and the crude and standardized incidence rates of thyroid cancer were 19.57/105 and 13.47/105, with APC of 18.15% and 17.93% ( P<0.05 ), respectively. The crude and standardized incidence rates of thyroid cancer were 10.02/105 and 7.06/105 in men, with APC of 19.58% and 19.04% ( P<0.05 ), and were 28.90/105 and 19.95/105 in women, with APC of 17.33% and 16.99% ( P<0.05 ), respectively. The crude incidence of thyroid cancer was higher in women than in men ( P<0.05 ). In addition, there were two peaks in the crude incidence of thyroid cancer in patients at age of 35 to 39 and 60 to 64 years, with crude incidence rates of 28.98/105 and 33.36/105, respectively. Conclusions The incidence of thyroid cancer appeared a tendency towards a rise in Huangpu District from 2002 to 2017, and much attention should be paid to females and patients aged 60 to 64 years.

Objective:To compare the safety and efficacy of medial-lateral pinning (MLP) and lateral pinning (LP) in pediatric supracondylar humeral fractures.Methods:According to PRISMA procedure, the randomized controlled trial (RCT) of pediatric supracondylar humeral fractures in PubMed (Medline), EMBASE, the Cochrane Library databases (Cochrane Controlled Trials Register for RCTs) and Wanfang Data from 1 January, 1990 to 1 January, 2020 were retrieved. Two researchers independently extracted the data and evaluated the quality of the original studies; the random-effects model was used for analysis.Results:A total of 4 679 original literatures were retrieved and 11 literatures were finally included, involving 920 children. Meta analysis results showed that there were no statistical differences in excellent ratio of elbow joint function (Flynn criteria), incidence of iatrogenic nerve injury and incidence of pin tract/ superficial infection between MLP group and LP group: 74.3% (255/343) vs. 72.9% (250/343), 6.1% (16/262) vs. 1.6% (4/246) and 5.3% (14/264) vs. 7.6% (20/262); RR = 0.98, 0.43 and 1.31; 95% CI 0.90 to 1.07, 0.18 to 1.03 and 0.64 to 2.67, P>0.05; the incidence of reduction loss in MLP group was significantly lower than that in LP group: 16.6% (51/307) vs. 23.9% (72/301), and there was statistical difference ( RR = 1.39, 95% CI 1.02 to 1.89, P = 0.04). Conclusions:MLP fixation and LP fixation are equally efficacious for supracondylar humeral fractures in children. MLP fixation may reduce the risk of reduction loss without increasing the risk of iatrogenic nerve injury. Manual reduction and MLP percutaneous Kirschner wire fixation for the treatment of displaced supracondylar humeral fractures in children is recommended.

Objective To investigate the protective effects of astragalosides Ⅳ (ASI) on high glucose-induced renal proximal tubular epithelial cells (NRK-52E).Methods NRK-52E were cultured and divided randomly into three groups:control group,high glucose group (HG in short),ASI groups (with various doses).Cells were treated with increasing concentrations of ASI (20,40,80 and 100 μg/ml) for 24 h in high glucose and we also stimulated cells in ASI 100 μg/ml with high glucose for various lengths of time.The apoptosis rate was detected by flow cytometric analysis.The mRNA and protein expression of transforming growth factor-β1 (TGF-β1),a-smooth muscle actin (α-SMA),Smad2,Smad3 and their phosphorylated forms were detected by real-time polymerase chain reaction (PCR) and Western blot,respectively.Results Compared with the control group,apoptosis was increased in the high glucose group (P ＜ 0.01).However,ASI inhibited high glucose-induced cell apoptosis in a dose-dependent manner,with a maximal inhibitory effect achieved at 100 μg/ml (P ＜ 0.05).The significant inhibition caused by ASI was observed at 8h after the start of pretreatment (P ＜ 0.05) and increased in a time-dependent manner.ASI can inhibit the expression of TGF-β1,α-SMA,Smad2,Smad3 both at mRNA and protein level.Conclusions ASI inhibited NRK-52E cells apoptosis induced by high glucose and reduced expression of TGF-β1,α-SMA,Smad2,Smad3 both at the mRNA and protein level in NRK-52E cells,thus delayed epithelial-to-mesenchymal transition progress.

Objective:To understand the quality of life of high risk population of stroke in community and analyze the influencing factors.Methods:Four community health service centers in Huangpu District were randomly selected, and the subjects were included by using convenient sampling method among the high risk groups of stroke found in the community stroke screening and prevention and control project in Shanghai.The World Health Organization quality of life scale-brief form questionnaire(WHOQOL-BREF), self-rating depression scale (SDS) and self-rating anxiety scale (SAS) were used as the survey tools to study 1200 high-risk stroke subjects.Single sample t-test was used to compare the differences between the scores and the data of 24 centers in the world, and multiple linear stepwise regression were used to analyze the influencing factors. Results:The scores of physical field, psychological field and social relationship field ((13.60±1.86), (14.58±1.97), (13.72±2.10)respectively) of high-risk population of stroke were lower than the scores of general population of 24 centers in the world ( P<0.01), and the scores of environmental field (14.08±1.95) were higher than it ( P<0.01), of which the differences were all statistically significant.The results of multiple linear stepwise regression analysis showed that old age, anxiety and depression were the risk factors influencing the scores of physical field( β=-0.027, -0.056, -0.051), psychological field( β=-0.019, -0.055, -0.050) and environmental field( β=-0.017, -0.040, -0.054); old age and depression were the risk factors influencing the scores of social relationship field( β=-0.026, -0.067); anxiety and depression were the risk factors influencing the self-assessment of quality of life and health ( β=-0.012, -0.014 for quality of life; -0.012, -0.014 for health, all P<0.01). Conclusion:The quality of life of high-risk population of stroke may be related to age, depression, anxiety and other psychological factors.The prevention and treatment of stroke should take both physical and mental measures, take timely intervention for poor psychological status, and gradually improve the quality of life.

There are millions of patients with taxane-induced peripheral neuropathy （TIPN）， and there is no effective treatment or prevention measure in clinical practice. The occurrence of TIPN may be related to the dosage form of paclitaxel drugs， genetic and molecular markers， drug dosage and chemotherapy cycle， patient factors， etc. At present， drugs for treating TIPN mainly include those that inhibit axonal degeneration （such as dosazosin， tamsulosin）， prevent mitochondrial dysfunction （such as glutathione trisulfides， antioxidants α -lipoic acid）， improve calcium imbalance in the internal environment （Shaoyao gancao decoction， N-type voltage-gated calcium channel inhibitor IPPQ）， and inhibit neuroinflammation （such as chemokine inhibitors and selective interleukin-8 receptor inhibitors DF2726A）. Further exploration of drug treatment strategies targeting different induction mechanisms is expected to become a new direction for precise clinical prevention and personalized treatment of TIPN.
