RESUMO
Objective:To observe any effect of repetitive transcranial magnetic stimulation (rTMS) on sleep disorders among children with cerebral palsy (CP).Methods:A total of 102 children with CP and disordered sleep were randomly divided into an experimental group and a control group, each of 51. All were given routine rehabilitation and sleep health education, but the experimental group additionally received rTMS for two weeks. The polysomnography (PSG) results of the two groups were recorded and analyzed.Results:The PSG parameters had improved greatly in both groups after the treatment. The percentage of N2 sleep (depth of sleep during light sleep) in the severe cerebral palsy group and of N3 sleep (depth of sleep during deep sleep) in the moderate cerebral palsy group had increased significantly more than in the mild cerebral palsy group, on average. After the intervention the percentages of N2 and N3 in those with mixed cerebral palsy and of N3 in those with involuntary motor cerebral palsy had increased significantly more than in those with spastic cerebral palsy, on average.Conclusion:rTMS treatment can improve the sleep disorders of children with cerebral palsy, especially N2 sleep among children with moderate to severe cerebral palsy, N3 sleep in cases of mixed or dyskinetic CP.
RESUMO
ObjectiveTo analyze the online public Q&A texts on HPV vaccine, focus on the important issues related to HPV vaccination and cervical cancer prevention in China, and propose strategies and suggestions. MethodsThe latent Dirichlet allocation (LDA) topic model was employed to extract key topics of 15 565 Q&A texts related to HPV vaccines from the social Q&A platform "Zhihu". The Baidu AI sentiment analysis tool was used to analyze the emotional tendencies of the texts corresponding to each topic, and the topics were classified based on the strategic coordinate method. ResultsOnline users focused on eight topics about HPV vaccine information. Among them, vaccination knowledge, HPV vaccination hesitation, and HPV vaccine development and marketing belonged to the low positivity-high negativity emotional topics, HPV infection and high-risk factors belonged to the low positivity-low negativity emotional topics, and HPV vaccine appointment channels, comparison between domestic and imported vaccines, HPV vaccines and cervical cancer prevention, and HPV vaccine types and selection were grouped under high positivity-low negativity emotional topics. ConclusionPublic concerns regarding HPV vaccines can be classified into three major dimensions: health knowledge, health beliefs, and health behaviors. Overall, the public's views and attitudes towards vaccine-related issues are not optimistic. Strengthening science publicity and education, enhancing vaccine supervision, and encouraging enterprises’ innovative research and development capability are effective strategies to improve public awareness of cervical cancer prevention and accelerate the full HPV vaccination coverage.
RESUMO
OBJECTIVE To mine the focus and emotional attitude of the public on rare diseases, and to provide decision- making reference for relevant departments to formulate and implement relevant policies, systems and strategies for medical security of rare diseases. METHODS Latent Dirichlet allocation (LDA) topic model and sentiment analysis method were used to analyze the comment text of short videos related to the “nosinasine” medical insurance admission event on the Bilibili video website, mine the theme and sentiment tendency of the text, and put forward relevant strategy suggestions. RESULTS A total of 8 videos with tens of thousands of playback and 7 109 text data were obtained. According to the LDA analysis, online public paid attention to 9 topics related to rare diseases (the price of rare disease drugs, the inclusion of rare disease drugs in medical insurance, the status quo of research and development of rare disease drugs, the scope of medical insurance and the medical security system, the plight of rare disease patients, the prevention and screening of rare diseases, the value of rare disease drugs in medical insurance, the Chinese and western medical methods of rare diseases, and the supply and demand status of rare disease drugs), which could be summarized into 4 categories according to the objects of concern (rare disease drugs, rare disease medical insurance, rare disease medical and health services and rare disease patient groups). On the whole, the emotional tendency of the Internet public towards each topic showed a low positive and high negative tendency. CONCLUSIONS The public paid more attention to the price, research and development, supply and demand of rare disease drugs, and was deeply worried about the current medical status of rare diseases in China. To strengthen and improve the medical security for patients with rare diseases, such as actively carrying out public health services for rare diseases, strengthening cooperation in the diagnosis and treatment of rare diseases, and researching rare disease drugs, etc. Chinese medical and health departments can make concerted efforts in medical and health services, drug supply security, medical security and other social security.
RESUMO
Objective:To compare the differences in sleep structure between healthy children and children with cerebral palsy (CP) using polysomnography (PSG).Methods:Fifty-six children aged 1-15 hospitalized for cerebral palsy formed the experimental group, while 30 healthy children served as controls. Both groups were given 24-hour PSG, and their sleep structures were compared and analyzed.Results:The incidence of sleep disorders in the children with cerebral palsy (55.4%) was significantly higher than among the healthy children (20.0%). The average sleep latency was significantly higher than among the healthy children, while the duration and the percentage of the rapid eye movement (REM) stage were significantly lower than among the healthy children. Total sleep time [(458.47±95.62)min], sleep efficiency [(74.26±13.63)%], duration of REM [(68.90±42.70)min] and REM percentage [(13.87±7.12)%] were all significantly lower for the children with severe cerebral palsy than for those with mild or moderate disorder. Their time to wake up after falling asleep was significantly longer. Moreover, the duration of REM and the REM percentage of children with dyskinetic cerebral palsy were significantly lower than for those with spastic cerebral palsy.Conclusions:The incidence of sleep disorders among children with cerebral palsy is higher than among healthy children. They have more difficulty in falling asleep and have a shorter REM stage. Children with severe cerebral palsy and involuntary cerebral palsy have more sleep problems.
RESUMO
Objective To design water-equivalent plastic scintillator detector for the measurement of absorbed dose in tumor radiotherapy.Methods The concentration of ZrO2to be doped in polystyrene was estimated according to the empirical formula,and then the Monte Carlo program Geant 4(GEometry And Tracking 4)was used to simulate the energy deposition and transport process of X-rays with different energies in water,solid water RW34(composed of 2.1 wt%TiO2doping polystyrene)and different concentrations of ZrO2particles doped in polystyrene.The dose and attenuation coefficients were compared among different materials at different depths of water.Results The doses at different depths and the attenuation coefficient of polystyrene(doped with about 0.4 wt%ZrO2nanoparticles)were much more consistent with those of water and even exhibit much better water-equivalence than RW34.Conclusions The simulation results provide the basis for the development of water-equivalent scintillator.
RESUMO
Hepatocellular carcinoma (HCC) is one of the most prevalent malignancies worldwide. Although surgery is known as the most promising radical treatment, a high recurrent or metastatic rate after surgery has limited its clinical efficacy. Sorafenib, a target agent, has seemed to be the only option for metastatic HCC patients to date, but none of clinical trials showed it could prolong the overall survival (OS) of advanced HCC to 1 year. How to prolong the OS and improve cure rate of HCC patients is still beset with difficulties. This report presents a rare case of recurrent HCC patient with complete regression of target lesion with 2 years of Chinese herbal treatment. A 64-year-old Chinese man with hepatitis B virus-associated chronic hepatitis presented HCC has been clinically diagnosed tumor relapse and omentum metastasis with computed tomography and α-fetoprotein blood test 4 months after surgery. It was decided the patient would receive traditional Chinese medicine treatment because of poor prognosis. After approximately 2 years of treatment, recurrent hepatic tumor and omentum metastasis have been found in complete regression. The patient remains alive over 31 months after relapse.

Objective To explore the diagnostic value of SPECT/CT on fracture healing.Methods A total of 28 patients (13 males,15 females; average age 45.3 years) with fracture were enrolled.All underwent metal fixation.SPECT/CT scans were performed at least 6 months after the metal fixation.X-ray examination before SPECT/CT showed equivocal fracture healing.The fracture delayed union or nonunion were judged by degree of uptake as well as uptake pattern around fracture site.Final diagnosis was confirmed by surgery or follow-up X-ray film.Results Among 28 patients,15 showed delayed union (confirmed by follow-up),and 13 showed nonunion (confirmed by surgery).There were 13 screws in 6 patients showed abnormal uptake,suggesting screw loose (confirmed by surgery).Conclusions SPECT/CT imaging could be of clinical significance in assessing fracture healing.
RESUMO
Objective To compare the effectiveness of CO2 laser treatment and routine scalpel procedure for facial sebaceous cyst (SC),and to compare cosmetic effect of laser welding and routine suture skin incision.Methods Two hundred patients with SC were randomly divided into two groups:CO2 laser operative treatment group (laser group),and routine scalpel operative treatment control group (control group),with 100 patients in each group.For the laser group,skins of SC were incised and cyst were extirpated using CO2 laser beam (power 20 W,diameter of light spot 0.2 cm and power density 637 W/cm2).If cyst wall was broken,then CO2 laser was used to gasify the residual.After cleaning skin incision,both border of incision with anastomat of laser welding skin was performed,next to welding skin incision with CO2 laser (power 1 W,diameter of light spot 0.2 cm and power density 32 W/cm2) scanning radiating 2 mm/s.For the control group,skins of SC were incised and cyst or residual wall were extirpated with single-use scalpel,and skin incisions were sutured with 1-0 silk thread by whole layer interrupted suture.Results For the laser group,97 cases (97 %) were cured,3 cases (3 %) improved.For the control group,87 cases (87 %) were cured,9 cases (9 %)improved and 2 cases (2 %) had no improvement.Cure rate of laser group was obviously higher than that of the control group (P<0.05).The cosmetic effect of the laser group was also better than that of the control group (P<0.01).For the laser group,successful rate of welding skin incision was 100 %.Conclusions Surgical removal of SC on face and welding skin incision with CO2 laser is very effective.The chances of recurrence and cicatrisation are greatly reduced.In particular,laser welding skin incision establishes a new non-suture reparable method of skin incision,which has important value for the cosmetic and plastic surgery.
RESUMO
Objective To observe the effect on Foxg1 gene expression in the subgranular zone (SGZ) of cerebral tissue from neonatal rats with hypoxic-ischemic brain damage (HIBD) after transplantation of neural stem cells (NSCs) derived from umbilical cord blood.Methods Mononuclear cells separated from umbilical cord blood by density gradient centrifugation were cultured with orientated induction to differentiate the NSCs.The neuronal phenotype was identified using immunocytochemical methods.A total of 150 Sprague-Dawley rats were randomly divided into a sham-operation group,an HIBD group and an HIBD-NSCs group.Rats in the HIBD group and the HIBD-NSCs group were subject to ligation of the left carotid artery and then kept in a box under 8% oxygen and 92% nitrogen for 2.5 hours to establish the HIBD animal model.The artery was separated but not ligated in the sham operation group,which was not subjected to hypoxia.Twenty-four hours after the operation,the cultivated NSCs were transplanted by caudal vein injection into the rats in the HIBD-NSCs group.Rats were then sacrificed on the 3rd,7th,14th,21st and 28th days after the operation.Foxg1 gene expression in the SGZ was examined using in-situ hybridization methods.Results The number of Nestin-positive cells peaked on the 6th day of cultivation and then decreased by the 9th day.The Foxg1 gene was expressed in the SGZs of each group.The expression increased by the 3rd day after surgery in the HIBD and HIBD-NSCs groups,and peaked on 7th day after the operation,then declined gradually.The average expression level of Foxg1 in the HIBD group was significantly lower than that in the HIBD-NSCs group on the 7th day and thereafter.Conclusions Human umbilical cord blood mesenchymal stem cells can be induced and differentiated into neural stem cells.Foxg1 genes can still be present in the SGZ after birth.HIBD can induce the expression of Foxg1 genes.Transplanting NSCs can promote the expression of Foxg1 genes and improve morphological and functional recovery after HIBD,at least in neonatal rats.

RESUMO
Objective To observe the effect of treatment and cosmetology in cbildren patients with strawberry hemangioma (SH) on face by three kind of infrared wavelength lasers.Methods In 300 children patients aged from 5 to 12 years with SH on face were randomly divided into a semi con ductor laser group (100 cases),a Nd ∶ YAG laser group (100 cases) and a CO2 laser group (100 cases).The parameters of laser were the same in the three groups,such as 10 W,light spot 0.2 cm in diameter and 318 W/cm2.According to size of area in the semiconductor laser and Nd ∶ YAG laser groups SH were coagulated by semiconductor laser and Nd ∶ YAG laser,and in the CO2 laser group it were gasified by CO2 laser,respectively.Children patients with SH were followed up for observation of cicatrzation and evaluation of the effect of therapeutics and cosmetology at six months after laser treatment.Results The cure rates were 89 % in the semiconductor laser group,83 % in the Nd ∶ YAG laser group and 69 % in the CO2 laser group (P<0.05).The excellent and faworahle rates of cosmetic effect were 87.0 % in the CO2 laser group,86.5 % in the semiconductor laser group and 57.8 % in the Nd ∶ YAG laser group (P<0.01).The analysis also showed that average therapeutic time,operative time and quantity of bleeding in the semiconductor laser group were less than that of in the Nd ∶ YAG laser and CO2 laser groups (P<0.01).Conclusions The semiconductor laser (wave length 830 nm and power 318 W/cm2) for the treatmet of children patients with SH on face has many advantages,such as higher cure rate,shorter operative time,less bleeding in operation and better cos metic effects.It might become a first selective therapy for children patients with SH on face.
RESUMO
Objective To investigate the effect of oleanolic acid (OA) on apoptosis, correlation between apoptosis and intracellular calcium, and its mechanism in human lung adenocarcinoma cell line A549. Methods Human lung adenocarcinoma A549 cells were incubated in vitro and assigned with OA concentrations of 0, 10, 20 and 40μg/mL. The apoptosis status of A549 cell line was detected with Annexin V-FITC/PI by flow cytometry (FCM); fluorescence intensity (FI) of A549 cells was assessed and the level of intracellular calcium was calculated at 24 hour of OA intervention. The relation between apoptosis and calcium FI was illustrated by curve fitting. Results FCM showed that 10, 20 and 40μg/mL of OA could induce A549 cell apoptosis, which followed a concentration-effect pattern; 24-hour intervention with 20μg/mL and 40μg/mL OA showed increased A549 cell apoptosis, and was significantly different from that with 0μg/mL OA (P<0.01). The FI of intracellular calcium concentration in 10, 20 and 40μg/mL OA groups was significantly higher than that in 0μg/mL group after 24 hours' intervention, and the FI showed a trend of increase with increased OA concentration (P<0.01). Curve fitting showed a significant correlation between apoptosis rate and intracellular calcium concentration in A549 cells (r=0.981, P<0.01). Regression equation was Y=0.508X-1.627. Conclusion OA plays a role in inducing apoptosis of human lung adenocarcinoma cells in a concentration-dependent manner. The OA-induced apoptosis is responsible for intracellular calcium overload of the tumor.
RESUMO
Objective To compare the effect of treating chronic colonitis diarrhea (CCD) using He-Ne laser irradiation of acupoints with routine drug treatment. Methods Two hundred patients with CCD were randomly divided into a laser irradiation group (laser group) and a routine drug treatment group (control group) with 100 patients in each group. The laser group patients were treated with a He-Ne laser ( power density 478 mW/cm2 )through coupling fiberoptic cable radiating onto the Shenque (REN8) , bilateral Tianshu (ST25) and Dachangshu (BL25) acupoints, each for 10 min daily for 10 days. Control group patients were treated with routine drugs such as antibiotics, astringents, antidiarrheals, antispasmodic analgesics, vitamins and Chinese herbal enemas. Three months after treatment the patients were examined by fibercoloscope to evaluate the therapeutic efficacy in the two groups. Results In the laser group 66 cases (66%) experienced a short-term cure, 27 cases (27%) improved and7 cases (7%) showed no effect. In the control group 33 cases (33%) were short-term cures, 43 cases (43%) improved and 24 cases (24%) had no effect. These differences were statistically significant. In both groups the effects for patients with short histories was better than for those with longer histories. In the laser group the pathological changes in the distal colon were significantly better than in the proximal colon, but this difference wasn't significant in the control group. The average days of total treatment to achieve short-term cure and improvement in the laser group were significantly less than in the control group. In the laser group the average days to the disappearance of abdominal pain and diarrhea in the short-term cure patients of was significantly fewer than in the control group. Conclusions Laser irradiation was more effective than routine drug treatment, especially for stopping diarrhea, spasmolysis and analgia.
RESUMO
Objective To investigate the changes in lung resistance-related protein (LRP) and vascular endothelial growth factor (VEGF) expressions and micro-vessel density (MVD) in non-small cell lung cancer (NSCLC), and to elucidate their possible relationship and mechanism. Methods Immunohistochemistry was used to detect changes in LRP and VEGF expressions, and MVD level in lung tissues of 56 NSCLC cases and 27 normal controls. Results ① LRP expression (66.1%) was concentrated in the cytoplasm of cancer cells, which was significantly higher than that in lung tissues of control group (P<0.01); the significance was not related to the pathological type. There was no significant difference in LRP expression among gender, TNM stage, lymph node metastasis, and two-year survival in NSCLC (P>0.05). ② In comparison to the control group, NSCLC group had significantly increased VEGF expression (P<0.01), which was not related to the pathological type. VEGF expression in NSCLC group had a significant association with TNM stage and lymph node metastasis (P<0.05). ③ The NSCLC group had a significantly higher MVD than the control group (P<0.01), which was not affected by the pathological type or degree. MVD value (18.5±5.8) of stage Ⅲ and Ⅳ in NSCLC group was significantly higher than that (13.8±5.1) of stage Ⅰ (P<0.05); MVD value for patients with lymph node metastasis was higher than that without lymph node metastasis (P<0.05); MVD value for patients with two-year survival was less than those who died within two years (P<0.01). ④ NSCLC group with high VEGF and LRP expressions had a consistently increased MVD value (P<0.05). Conclusion There is a certain relationship between tumor angiogenesis and LRP expression in NSCLC. VEGF is responsible for the high expression of LRP through up-regulating LRP gene and augmenting tumor MVD. Inhibition of angiogenesis in tumor is expected to reduce or inhibit drug resistance to NSCLC.
