Objective:To analyze the current development status and spatial distribution characteristics of traditional Chinese medicine (TCM) hospitals in China, predict the changing trends of the number of TCM hospitals, the number of beds, and the number of physicians, and provide references for the development of TCM hospitals and the formulation of related policies.Methods:From the official websites of the National Bureau of Statistics and the State Administration of Traditional Chinese Medicine, the total population and number of TCM hospitals of 31 provinces (excluding China′s Hong Kong, Macao, and Taiwan) in China from 2013 to 2022 were included, as well as the number of beds and practicing (assistant) physicians in TCM hospitals from 2013 to 2021. The grey prediction model was applied to predict the changing trends of the number of TCM hospitals, beds and physicians. Using the global Moran′s I index in spatial autocorrelation analysis, the distribution of TCM hospitals per 10 000 people in China was analyzed by spatial correlation analysis, and local G coefficient was analyzed by local hot spots.Results:From 2013 to 2027, the number of TCM hospitals, beds and practicing (assistant) TCM physicians in China all showed an increasing trend year by year. The number of TCM hospitals per 10 000 people in China showed a spatial correlation between 2013 and 2022 ( P<0.05). The hot spots of TCM hospitals were mainly concentrated in North China and Northeast China, while the cold spots were mainly concentrated in southeast coastal areas and Northwest China. Conclusions:The number of TCM hospitals in China is increasing year by year, but it is necessary to control the reasonable increase and avoid blind expansion. It is necessary to formulate regional policies of TCM hospitals according to local conditions and pay attention to the individuation of policies. Focus on hot and cold areas to promote balanced development of TCM hospitals.

Objective To explore the effect of exercise under cold exposure on hepatic protein ki-nase B(AKT)/forkhead box O1(FoxO1)expression in obese rats.Methods Among rats successfully induced nutritional obesity by high-fat diet,forty were selected and randomly divided into a normal-temperature control group(NC,n=10),a normal-temperature exercise group(NE,n=10),a sus-tained-cold control group(SC,n=10),and a sustained-cold exercise group(SE,n=10).The normal temperature was kept at 25°C±1°C,while the low temperature remained at 4°C±1°C,with 50%to 60%relative humidity.The exercise protocol was every other day at a speed of 25 m/min for 2 sets of 30 min each,with an interval of 10 minutes.After 5 weeks,glucose and insulin tolerance were tested by oral glucose tolerance test(OGTT)and insulin tolerance test insulin tolerance test(ITT).Then,all rats were weighed and sacrificed,then taken blood from the abdominal aorta to sepa-rate serum,followed by detection of serum alanine aminotransferase(ALT)and aspartate aminotransfer-ase(AST)levels using fully automatic biochemical analyzer.Moreover,livers were weighed to calcu-late the liver index.Meanwhile,the mRNA expressions of hepatic AKT,FoxO1 and PEPCK were de-tected using RT-qPCR,while the protein expressions of AKT,phosphorylated protein kinase B(p-AKT),and FoxO1 in the liver were measured using Western blotting.Results(1)The average body weights of the NE,SC and SE groups were significantly lower than the NC group(P<0.01),with that of the SC and SE groups significantly lower than the NE group(P<0.01).(2)Compared with the NC group,the area under the OGTT curve of the SC group decreased(P<0.01).Moreover,the area under the ITT curve of the SE group was significantly lower than the other 3 groups(P<0.01,P<0.01,P<0.05),with that of the NE and SC groups significantly lower than the NC group(P<0.05,P<0.01).(3)The liver indices of the NE,SC and SE groups were all significantly lower than the NC group(P<0.01),while the serum ALT level of the NE group was significantly lower than the NC and SE groups(P<0.05),with that of the SC group significantly lower than the NC group(P<0.01).(4)Compared with the NC group,hepatic AKT mRNA expression increased significantly in the SE group(P<0.05),while the hepatic FoxO1 and PEPCK mRNA expression decreased significantly in the other three groups(P<0.01).(5)Compared with the NC group,the liver AKT protein phosphorylation levels were significantly higher in the other three groups(P<0.05,P<0.05,P<0.01),while the FoxO1 protein expression decreased significantly(P<0.05,P<0.01,P<0.01).(6)Body mass,liver FoxO1,PEPCK mRNA expression,AKT protein phosphorylation level and FoxO1 protein expression level of obese rats were affected by cold exposure,exercise and cold exposure+exercise,and the liver index and serum ALT level were done by exercise and cold exposure+exercise.However,the area un-der the ITT curve and liver AKT mRNA content were impacted by cold exposure and exercise,while that under the OGTT curve was influenced by cold exposure and cold exposure+exercise.Conclu-sion Exercise under cold exposure can activate hepatic AKT/FoxO1 signaling pathway,protect liver function,increase insulin sensitivity,and effectively improve glucose metabolism in obese rats.

Objective To investigate the clinical efficacy of three-dimensional conformal radiotherapy combined with XELOX program chemotherapy in the treatment of postoperative local recurrence of rectal cancer.Methods One hundred and twenty-nine patients with postoperative local recurrence of rectal cancer were divided by random digits table method into treatment group (65 cases) and control group (64 cases).The patients in treatment group were treated with three-dimensional confonmal radiotherapy combined with XELOX program chemotherapy.The patients in control group were treated with XELOX program chemotherapy.The short-term effect,symptom control rate,long-term efficacy and adverse reaction were observed.Results The efficiency rate in treatment group [ 90.8％ (59/65) ] was significantly higher than that in control group [ 73.4％(47/64) ] (P ＜ 0.05 ).The improvement rates of pain,hematochezia and incomplete obstruction between treatment group and control group had significantly statistical differences [95.2％(40/42) vs.75.0％(27/36),92.9％(26/28) vs.79.5％(31/39),94.7％(18/19) vs.75.0％(9/12)](P ＜0.05).The 1,2,3-year survival rates between treatment group and control group had significantly statistical differences [ 67.7％ ( 42/62 ) vs.43.5 ％ ( 27/62 ),53.2％ ( 33/62 ) vs.30.6％ ( 19/62 ),38.7％ ( 24/62 )vs.14.5％ (9/62)] (P ＜ 0.01 ).The adverse reaction in two groups were mainly bone marrow suppression,gastrointestinal reactions,hand-fcot syndrome and radiation cystitis.The incidence rate of adverse reaction in treatment group was slightly higher than that in control group,but there was no significant difference between two groups (P ＞ 0.05).Conclusion Three-dimensional conformal radiotherapy combined with XELOX program chemotherapy in patients with postoperative local recurrence of rectal cancer can improve the short-term effect,symptom control rate and long-term survival rate.

BACKGROUNDThere is no effective regimen for recurrent small cell lung cancer patients now. The aim of this study is to assess the activity and toxicity of topotecan combined with cisplatin in the treatment of recurrent small cell lung cancer patients.

METHODSTwenty-eight patients with progressive disease after one first-line regimen enrolled in the study from May 2002 to October 2004. Topotecan was given at the dose of 1.2mg/m² from 1st to 4th days and cisplatin was administered at the dose of 25mg/m² from 5th to 7th days in a cycle of 3 weeks. The patients could be evaluated at least after 2 cycles.

RESULTSOne patient got complete response and ten patients got partial response in this group. The overall response rate was 39.3% , and the response rate of refractory group and sensitive group was 37.5% (3/8) and 40.0% (8/20) respectively. The median time to progression was 4.2 months. The main toxicity was hematological toxicity. Grade III+IV neutropenia occurred in 42.9% (12/28) of the patients.

CONCLUSIONSThe regimen of topotecan and cisplatin shows better activity in retreated small cell lung cancer patients. The main toxicity is hematological toxicity and can be tolerated.
