Objective To accurately measure the length of naso-gastric tube for infants by adopting ap-propriate body surface measurement. Methods We chose 60 infants and adopted two methods to measure the length of tube,one was the new method by which we measured the distance from the middle of hair border of forehead to umbilicus and the other was the traditional method by which we measured the distance to xiphoid process from the same beginning point as the new method.Then we compared the results from the two methods with the actural length of the tube. Results The result of the traditional method was statistically different from the actural length of the tube (P ＜ 0.01 )But the result of the new method was near to the actural length of the tube (P＞ 0.05). Conclusions The result of the new measuring method was near to the actural length of the naso-gastric tube and was suitable to the infants.It reduced the adverse effect caused by the traditional method and improved the effect of diagnosis and treatment greatly.So we advocated to measure the distance from the middle of hair border of forehead to umbilicus as the length of naso-gastric tube.

ObjectiveTo discuss the impact of conflict psychological stress on rats'sleep time and sleep phrase.Methods20 Wistar male rats were randomly divided into vehicle group and model group,10 in each group.The improved experiment of Vogel drinking water conflict was used to establish the model of conflict psychological stress in rats and monitoring the changes of rats'weight and concentration of corticosterone (CORT) in serum after a week.After one week,the 12 h EEG and EMG of rats were traced by the polygraph in order to clarify the effect of conflict psychological stress on rats′ sleep time and sleep phrase.ResultsAfter one week,compared with vehicle group the weight of model group decreased significantly ( t =2.87,P ＜ 0.05 ),the concentration of CORT in serum raised significantly( t=5.19,P ＜ 0.05 ).A week later,compared the vehicle group,total sleep time( TST),light sleep,slow wave sleep(SWS) and rapid eye movement sleep (REM) time in model group rats ( (337.8 ±84.2)min,( 169 ±49.2) min,( 136.9 ±40.8)min,(33.1 ± 10.1 ) min for vehicle group; ( 155.4 ±16.7 ) min,( 111.6 ± 16.4 ) min,( 30.6 ± 4.9 ) min,( 12.6 ± 3.3 ) min for model group) were significantly reduced ( t =6.75,2.43,5.51,5.78,P ＜ 0.05 ),and the proportion of lightsleep increased ( (49.6 ± 3.4 ) ％,( 71.7 ±5.4)％ ) ( t =6.90,P＜0.05),the proportion of SWS decreased( (40.3 ± 10.9)％,( 19.8 ±3.2)％ ) ( t=6.74,P ＜ 0.05 ) ;but no significant change in the proportion of REM ( t =1.57,P＞ 0.05 ).Rats,sleep-wake rhythm figure indicated that the rats'sleep duration reduced and the number of awakening increased ; sleep tended to be fragmentation.ConclusionsConflict psychological stress lead to hypothalamus-pituitary-adrenal axis hyperactivity,weight loss,and the rhythm of sleep and sleep phase change in rats.

Objective We aimed to assess the sedative effects by intravenous injection of fentanyl on neonates with mechanical ventilation. Methods We divided 142 neonates with mechanical ventilation into the observation group (92 cases) and the control group (50 cases). The observation group received intravenous injection of fentanyl, while the control group was given no sedative medication. The pain and sedation was assessed before ventilation, 1 and 2 hours after ventilation and later every 4 hours by adoption of NPASS evaluation inventory. Results The scores of pain at different time points 2 hours after medication in the observation group were lower than those in the control group, especially 24 hours after medication. The mean airway pressure and oxygen concentration required by the observation group was lower than those of the control group. But no difference was seen in blood oxygen saturation between the two groups. Conclusions Intravenous injection of fentanyl was proper in the application of sedative treatment for neonates with mechanical ventilation. N-PASS inventory could effectively assess the pain and sedation condition and ensure the safe medication.

Objective To study the clinical features and CT findings of pulmonary fungal infection(PFI) secondary to malignant tumor.Methods The clinical features and CT findings of PFI secondary to malignant tumor proved clinically and pathologically were analyzed retrospectively.Results In pulmonary fungal infection,pulmonary candidiasis was most common seen,which were found in 34 (68%) of 50 cases.CT findings of PFI usually consist of a mixture of patterns,ground-glass attenuation(n=31,62%)and air-space consolidation (n=29,58%) were most common CT findings. Other CT findings included nodule(n=20,40%), air cresceut sign (n=2,4%), thickening of bronchovascular bundles (n=7,14%), mass (n=1,2%),tree-in-bud appearance(n=5,10%),cavity(n=3,6%).Conclusion CT findings of PFI secondary to malignant tumor were nonspecific,which can’t distinguish from other pneumonia,to pay more attentions on it is necessary.

Objective To analyze the endemic situation of schistosomiasis after its interruption of transmission in Xiuzhou District,Jiaxing City,Zhejiang Province,so as to provide the references for future surveillance work. Methods The data of schistosomiasis and Oncomelania hupensis snails in Xiuzhou District were collected and analyzed statistically. Results From 1994 to 2015,totally 975 village?times were investigated for O. hupensis snails,and the accumulated area of 4 385.31 hm2 was surveyed. Twenty former snail sites were reoccurring,with an area of 32.61 hm2. An area of 57.71 hm2 was supplied with snail eradication measures. Totally 11 941 snails were dissected and no schistosome infected snails were found. The serum and stool tests were performed to 221 794 and 3 731 residents respectively,and no local infection cases but four imported cases were found. Conclusion The endemic situation of schistosomiasis in Xiuzhou District is stable after the transmission was interrupt?ed. However,there are imported schistosomiasis cases,and therefore,the prevention of imported infection source is the focus of surveillance work.

Objective To comparatively analyze the application of conventional echo planar imaging-diffusion weighted imaging (EPI-DWI) and readout-segmented echo-planar diffusion imaging (RESOLVE) in the diagnosis of nasopharyngeal carcinoma.Methods A total of 35 patients with nasopharyngeal carcinoma confirmed by pathology were included in this study.All patients underwent conventional EPI-DWI and RESLOVE (b=800 s/mm2) with a 3.0 T MRI scanner.ADC values of the tumors and normal nasopharyngeal tissues were calculated.Scoring (Five-point score) for imaging quality of conventional EPI-DWI and RESLOVE was independently performed by two radiologists with 5 years experiences and the agreement evaluation was performed using Kappa analysis.The numbers of cases with effectively ADC values,the ADC values of the same tissue in different sequences and the ADC values of the tumor and the normal muscle tissue in the same sequence were compared.The data was statistically analyzed by x2 test,paired sample t test and independent sample t test.Results The agreement between two radiologists was excellent.The Kappa value of the conventional EPI-DWI was 0.91 1(P＜0.01).The Kappa value of the RESOLVE was 0.827(P＜0.01).Four points or more accounted for 97.1％ (34/35) in the RESOLVE group,while only 2.9％ (7/35) images scored four points and most of them were less than four points in the conventional EPI-DWI group.The effectively ADC values can be measured in the conventional EPI-DWI,accounting for 54.3％ (19/35) cases.The ADC values could be measured in all cases of group (100.0％,35/35).The scores of imaging quality of RESOLVE were higher than those of conventional EPI-DWI,which were significantly different (x5=19.091,P＜0.001).The ADC values of the normal nasopharyngeal tissue were (1.65 ±0.13) × 10-3,(1.96±0.14) × 10-3 mm2/s and the ADC values of the tumor were (0.87±0.09) × 10-3,(0.83±0.10)× 10-3 mm2/s in the conventional EPI-DWI and the RESOLVE,respectively.The ADC values were significantly different between the tumors and the normal nasopharyngeal tissues (t=-23.284,-31.509,P＜0.05).The ADC values of the tumors were apparently lower than the normal nasopharyngeal tissues.There were no significant difference of the ADC values between the conventional EPI-DWI and the RESOLVE measuring the same tissue (t=-0.957,-0.921,P＞0.05).Conclusion Compared with conventional EPI-DWI,RESLOVE can provide a higher quality image and may be helpful to accurate diagnosis.

OBJECTIVE: To study the regulatory effect of IL-35 on the balance of Treg/Th17 cells in AR patients. METHOD: In this study, 30 cases were randomly selected from outpatients of otolaryngological department in the second hospital of Hebei Medical university who were diagnosed as AR. Another 20 healthy cases enrolled from physical examination branch of our hospital were control group. The expression level of IL-35 and IL-17 in peripheral blood were detected by using ELISA and defeced CD4+CD25+Foxp3+ T cell and CD4+IL-17+T cell expression level were identified via flow cytometry. RESULT: The expression level of IL-35 in AR group was obviously lower than that in control group, and the difference was a statistically significance (t = -8.145, P < 0.01). The expression level of IL-17 in AR group was obviously higher than that in control group, and the difference was a statistically significance (t = 14.969, P < 0.01). There was a remarkable negative correlation between the IL-35 and IL-17 expression in the serum of AR group (r = -0.773, P < 0.01). The percentage of CD4+CD25+Foxp3+ T cell in CD4+ T cell was significant lower in AR group than that in control group (t = -13.678, P < 0.01). The percentage of CD4+IL-17+ T cell in CD4+ T cell was much higher in AR group than that in control group (t = 5.632, P < 0.01). There was a remarkable negative correlation between the Treg and Th17 expression in the peripheral blood of AR group (r = -0.613, P < 0.01). There was a positive correlation between the expression of CD4+ CD25+Foxp3+ T cell and IL-35. There was a negative correlation between the IL-35 and Th17 in AR group (r = 0. -594, P < 0.01). CONCLUSION The lower expression of IL-35 was related to the incidence of AR, and it was an important cytokines for that. The lower expression of IL-35 may inhibit the proliferation of Treg cells, lead to hyper function of Th17 cells, increase secretion of s IL-17 and result in unbalance of Treg/Th17 cells; these may be the important mechanism of the occurrence of AR, thus regulation of IL-35 may become a new target for the immunological therapy of AR.

Objective　To study the clinical and epidemiological characteristics of the monkeypox epidemic in Longgang District, Shenzhen, and conduct a comprehensive analysis and discussion to provide a reference for monkeypox epidemic prevention and control. Methods An epidemiological investigation was conducted on 16 monkeypox cases found in the medical institutions of Longgang District on June 2023. The distribution of cases, high-risk exposure characteristics (contact objects, methods, locations, etc.), incidence characteristics, and medical treatment situation were analyzed. Relevant discussions on epidemic prevention and control were further conducted in light of the actual situation and the problems encountered. Results The cases were all unmarried young men and men who have sex with men (MSM) population. The disease was transmitted from person to person through same-sex contact, with non-fixed sexual partners as the source of infection and exposure locations being relatively concealed, and the average incubation period was 8.42 days. Most cases were discovered through active seeking medical attention, accounting for 68.78% (11/16). Fever was the primary initial symptom accounting for 56.25% (9/16), with the main symptoms being a rash and fever, at 100% and 68.75% (11/16), respectively. Time from fever to rash onset was mainly 0-3 days, accounting for 90.91% (10/11). The eruption site involveed multiple different parts of the body, and there was no special order of eruption. The time interval from onset to seeking medical attention and from onset to discovery was similar, with 5.91 days and 5.94 days respectively. The majority of cases were HIV infected, accounting for 68.75% (11/16)。Conclusions The monkeypox epidemic is prevalent in MSM populations and is transmitted through male to male contact through human transmission. However, due to unstable sexual partners and concealed exposure locations, tracing the source is difficult, with an average incubation period of 8.42 days. The symptoms are mainly fever and rash, with a long time from onset to medical treatment. The initial manifestations are mild, leading to missed diagnoses on the first visit, resulting in difficulty in timely discovery and prevention of further cases. At the same time, investigating and handling the epidemic are challenging, making the prevention and control of the outbreak a difficult task.

Objective:To explore the effect of acupoint massage combined with upper limb rehabilitation training in the functional exercise of the affected limb of patients after modified radical mastectomy for breast cancer.Methods:From February 2018 to April 2020, convenience sampling was used to select170 patients after modified radical mastectomy for breast cancer admitted to Fuyang Cancer Hospital as the research object. The patients were divided into the observation group and the control group with 85 cases in each group by random number table method. The control group conducted pressure cuffs and upper limb rehabilitation training, and the observation group carried out acupoint massage on the basis of the control group. The upper limb function, the incidence of lymphedema and the quality of life were compared between the two groups.Results:One case fell off in the observation group, 4 cases fell off in the control group, and finally 84 patients were included in the observation group, and 81 patients were included in the control group. Three months after the operation, the angles of abduction, flexion and extension of the affected limb of the observation group were greater than those of the control group, and the difference was statistically significant ( P<0.05) . Three months after the operation, the incidence of upper limb lymphedema in the observation group was lower than that in the control group, and the difference was statistically significant ( P<0.05) . Three months after the operation, the total scores of the Chinese version of Function Assessment of Cancer Therapy-Breast and the scores of social/family well-being, functional well-being, and emotional well-being of the observation group were higher than those of the control group, and the difference was statistically significant ( P<0.05) . Conclusions:Acupoint massage combined with upper limb rehabilitation training can help promote the recovery of the function of the affected limb after the modified radical mastectomy for breast cancer, and reduce the incidence of lymphedema in the affected limb, and improve the quality of life of patients.
