Objective To summarize the diagnostic and therapeutic experience of a patient with chronic graft versus host disease (cGVHD) related polymyositis (PM) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).Methods A patient with acute lymphocytic leukemia in com- plete remission received sibling allo-HSCT,and cyclosporine and methotrexate were adopted to pre- vent GVHD.Results Eleven days after HSCT,WBC＞0.5?10~9/L,13 days after HSCT,PLT＞20?10~9/L;27 days after HSCT,chromosome analysis of bone marrow cells showed 99% donor type. Seventeen days after HSCT,Ⅰ~0 acute GVHD of skin occurred,and it was cured by intravenous injec- tion of dexamethasone and methotrexate.Eight months after HSCT,cGVHD of liver happened.Al- though treated by tacrolimus and azathioprine,enzymes of liver were still elevated.At last,tacrolimus combined with sirolimus were used,and enzymes of liver subsided gradually.However,the serum creatine phosphokinase (CK) began to rise from 9 U/L to 3010 U/L,and fatigue all over the patient occurred.Finally,the symptom relapsed,and disability involved with the origin of limbs appeared. The electromyogram and magnetic resonance imaging of concerned muscles confirmed the PM diagno- sis.Although treated with methylprednisolone and plasma exchange,the patient died due to asphyxia, while the CK as high as 21 010 U/L.Conclusion PM is a rare kind of manifestations of cGVHD. When the key muscle tissue was involved,the prognosis is poor.

Objective: To investigate the epidemiological characteristics of rabies-exposed populations in Anji County, Zhejiang Province from 2017 to 2021, so as to provide insights into rabies control in the county. Methods: All data pertaining to rabies were captured from Monthly Report of Rabies-exposed Populations in Huzhou City and Investigation Form of Multiple Dog Injuries reported by dog injury clinics in Anji County from 2017 to 2021, and the species of animals causing dog injuries, duration, degree and site of exposure, and post-exposure treatment of rabies-exposed populations were descriptively analyzed. Results: Totally 46 186 cases with rabies exposure were reported in dog injury clinics in Anji County from 2017 to 2021, and the rate of exposure appeared a tendency towards a decline year by year (Z=-23.249, P<0.001), with an annual mean exposure rate of 1 739.59/105. The number of cases with exposure to rabies peaked in July and August (10 066 cases, 21.79%). Dogs were predominant animals causing injuries (31 732 cases, 68.70%), and the rate of exposure to dog bites appeared a tendency towards a decline year by year (Z=-35.541, P<0.001). There were 11 350 cases with cat-causing injuries (24.57%), and the rate of exposure to cat bites appeared a tendency towards a rise (Z=14.834, P<0.001). Lower extremity was the main site of exposure (22 364 cases, 48.42%), and the proportions of grade Ⅱ and Ⅲ exposure to rabies were 72.85% and 25.23%, the rates of exposure both appeared a tendency towards a decline (Z=-14.522, P<0.001; Z=-21.820, P<0.001). The proportion of using human rabies immune globulin was 25.72% among populations with grade Ⅲ exposure, which appeared a tendency towards a rise (Z=6.636, P<0.001). Conclusions The rate of exposure to rabies appeared a tendency towards a decline in Anji County from 2017 to 2021. Dogs were predominant animals causing injuries, and the rate of cat bites appeared a tendency towards a rise from 2017 to 2021; however, the proportion of using human rabies immune globulin remains to be improved among populations with grade Ⅲ exposure.

BACKGROUND: Moxibustion can improve the symptoms of rheumatoid arthritis and reduce inflammation, but there are no uniform operation standards. The moxibustiondistance becomes one of factor influencing the therapeutic efficacy.OBJECTIVE: To compare the effects of different moxibustion distances on rheumatoid arthritis, and to explore the optimal distance.METHODS: The 8 of 40 male Sprague-Dawley rats were randomlyselected as controls. The other 32 were used to make animal modes of collagen type Ⅱ-induced ankle arthritis, and then given moxibustion at Shenshu (BL23) and Zusanli (ST36) at an interval of 1, 2 and 3 cm, respectively, once daily, 10 minutes at each point, 6 days per course for three courses, with a course interval of 1 day. Model rats with no treatment acted as model group.RESULTS AND CONCLUSION: Compared with the control group, the toe volume, arthritis index and serum levels ofinterleukin-1β and tumor necrosis factor-α except the body mass were significantly increased in the model group (P < 0.01).After moxibustion treatment, these indexes were significantly decreased in the three treatment groups (P < 0.01), especially in the 1 and 2 cm groups (P < 0.01). Narrowed articular cavity, intra-articular inflammation and pannus formation were observed in the model group, while only moderate inflammatorycell infiltration and few pannus formation were found in the 1,2, 3 cm groups. These results indicate that moxibustion improvesjoint functions and regulates immune reaction by downregulating the levels of interleukin-1β and tumor necrosisfactor-α, as well as reducing synovial hyperplasia. In addition,the optimal distance for moxibustion is 1 or 2 cm, which is amomentous proposition to improve therapeutic efficacy.

Objective To evaluate the reliability and validity of the Chinese version of the Newest Vital Sign(NVS). Methods The NVS was translated and back-translated. Cultural adaption of scale was performed by Delphi expert consultation and pilot study. The reliability and validity of the Chinese version of the NVS was tested in 451 Chinese residents. Results Chinese version of the NVS consisted of 6 items with Pearson correlation between item and total score of scale ranging from 0.50 to 0.71. Two factors were abstracted by exploratory factor analysis and explained 61.51% of total variance. Confirmatory factor analysis showed that the fitness of the model was acceptable:comparative fit index was 0.96, Tuker-Lewis index was 0.92, standardized root mean square residual was 0.04, root mean square error of approximation was 0.077. Cronbach α coefficient was 0.71, retest reliability was 0.92. Conclusions Chinese version of the NVS has good reliability and validity, which can be used to test the health literacy of residents in China.

Objective: To observe the effect of different moxibustion durations on rats with rheumatoid arthritis (RA) and to evaluate the relationship between moxibustion amount and moxibustion efficacy.Methods: Eight rats were randomly selected as a normal group from the 40 male Sprague-Dawley (SD) rats, and the other 32 rats were used to establish typeⅡ collagen-induced RA models. After successful modeling, the 32 rats were randomly divided into a model group, a moxibustion for 20 min group, a moxibustion for 40 min group and a moxibustion for 60 min group, with 8 rats in each group. Rats in the normal group did not receive modeling and moxibustion intervention; rats in the model group did not receive moxibustion after modeling; rats in the moxibustion for 20 min group, the moxibustion for 40 min group and the moxibustion for 60 min group were treated with moxibustion at Shenshu (BL 23) and Zusanli (ST 36) for 20 min, 40 min and 60 min, respectively. Six days were a course of treatment, with a total of 3-course treatments and a 1-day rest between the courses of treatment. After treatment, the serum levels of interleukin (IL)-1β and tumor necrosis factor (TNF)-α, arthritis index (AI) scores, toe volumes and pathological score of synovitis were evaluated in the rats.Results: Compared with the normal group, the serum IL-1β and TNF-α levels, and the toe volumes in the model group were increased, and the differences were statistically significant (P<0.01), before the treatment. Compared with the model group, the serum IL-1β and TNF-α levels, toe volumes and arthritis index (AI) scores were significantly decreased in the moxibustion for 20 min group, the moxibustion for 40 min group and the moxibustion for 60 min group (P<0.05 orP<0.01 ). Compared with the moxibustion for 20 min group and the moxibustion for 60 min group, serum IL-1β and TNF-α levels, toe volumes and AI scores were decreased more significantly in moxibustion for 40 min group, and the differences were statistically significant (P<0.05 orP<0.01). There were no significant differences in serum IL-1β and TNF-α levels, AI scores and toe volumes between the moxibustion for 20 min group and the moxibustion for 60 min group (allP>0.05). The synovial histopathological improvement was the most obvious in the moxibustion for 40 min group, when the synovial histopathological changes were compared among the moxibustion for 20 min group, moxibustion for 40 min group and moxibustion for 60 min group.Conclusion: The therapeutic efficacy of moxibustion for 40 min in RA rats was more significant than that of moxibustion for 20 min and moxibustion for 60 min, indicating that the duration of moxibustion is the main factor affecting its therapeutic efficacy.

In this paper, taking Shijiazhuang city, Hebei province as an example, a random sampling of 30 streets in three districts were investigated the use of tactile ground surface indicator. The survey showed that 69% of the existing tactile ground surface indicator were used normally, while 8%were laid unreasonable, 11%were occupied and 12%were damaged. Suggestions were set from three aspects:sci-entific and reasonable laying, strengthening supervision and maintenance, and strengthening publicity and education, so as to improve the current situation of tactile ground surface indicator, improve the utilization rate, promote the participation of visually impaired persons in so-cial life and improve their quality of life.
