Objective To explore the effects of early rehabilitation on premature infant with brain damage. Methods101 premature infants with brain damage in were divided into experimental group （n=45） and control group （n=56）. The experimental group received medicine and early rehabilitation. The control group received medicine only. Developmental evaluation were performed in 3, 6, 9, and 12 months old. ResultsThere were no significant differences of the Neonatal Behavioral Neurological Assessment (NBNA) scores between these two groups （P＞0.05）. Except infants of 3 months old, the developmental quotient (DQ) and mental index (MI) of 9, 12 months old infants of the experimental group were higher than that of the control group （P＜0.01）. The sequelae of the experimental group were less than that of the control group （P＜0.05）. ConclusionEarly rehabilitation can promote development of premature infant with brain damage and reduce the sequelae.

OBJECTIVEFrictions of Lock-loose brackets with ligated main wings or all six wings were measured as they slid along archwires in dry and artificial saliva environments. The Lock-loose brackets were then compared with traditional brackets and self-ligating brackets.

METHODSThe surface states of the stainless steel archwires were observed with atomic force microscopy before and after mechanical traction. The Lock-loose brackets, traditional brackets, and self-ligating brackets used in this study were composed of 0.406 4 and 0.457 2 mm stainless steel round archwires and 0.457 2 mm x 0.634 9 mm and 0.482 6 mm x 0.634 9 mm stainless steel rectangular archwires. Two different ligating methods were applied to the Lock-loose brackets, i.e., main wings ligated and all six wings ligated. Frictions were measured by using an electronic universal testing machine.

RESULTSNo significant differences were found between the roughness of different archwires before and after mechanical traction in different brackets (P > 0.05). When the main wings of the Lock-loose brackets were ligated, the frictions of the four different stainless steel archwires were close to zero, and the difference with frictions of traditional brackets was significant (P < 0.05). When using 0.457 2 mm x 0.634 9 mm rectangular archwires, maximum friction (P < 0.05; significantly different from those of other brackets) was reached when all six wings of the Lock-loose brackets were ligated. Frictions in the dry state were higher than those in the wet state (P < 0.05).

CONCLUSIONThe Lock-loose brackets can adjust the friction efficiently with different ligating methods, thus solving the problem of low friction and strengthening anchorage.

Objective:Gastrointestinal heat retention syndrome (GHRS) is associated with lung-heat syndrome and is related to recurrent respiratory infection.Upper respiratory tract infection (URTI) lung heat syndrome is common in children.The study will explore the effect of GHRS on the structure and function of gut microbiota in children with URTI lung-heat syndrome.Methods:Participants were divided into both groups using the self-developed URTI scale and the "GHRS Diagnostic Scale · Pediatric Part":GHRS-positive children (LS group) and GHRS-negative children (L group).General information,clinical symptoms,and stool were collected.We used 16S rRNA amplicon sequencing technology to determine the gene sequence of the V3-V4 region in feces and measure the gut microbiota of the both groups at the genus level.Results:A total of 23 children were included in the both groups.There were 12 cases in the LS group and 11 cases in the L group.There was no statistical difference between the both groups in age,gender,height,weight,and body mass index.The effective sequences shared by the both groups accounted for 85.66％ of the total.In the gut microbiota,there was no difference in the α diversity and the β diversity between the both groups.Compared with the L group,the LS group had a significant increase in the relative abundance of the Rurninococcus gnavus group,Prevotella-9,Staphylococcus,and Actinomyces(P ＜.05).The functions of the both groups of microbiota primarily concentrate on metabolism,genetic information processing,and environmental information processing.The relative abundance of signaling molecules and interactions in the LS group were higher than that in the L group (P ＜.05).The redun-dancy analysis (RDA) showed that the URTI score had the greatest impact on the distribution of microbiota.Conclusion:GHRS may affect the development of URTI lung-heat syndrome by changing the relative abundances of gut microbiota.

OBJECTIVETo assess the efficacy of sacral neuromodulation (SNM) in patients with intractable constipation.

METHODSA total of 7 patients with intractable constipation were treated with pereutaneous test stimulation of the S3 nerve root and were assessed by sacral never stimulation system in our department from January 2013 to January 2014. Four of these 7 patients received operation for constipation before. The efficacy was assessed by bowel habit diary, clinic constipation scores, subjective questionnaire and clinical signs.

RESULTSThe constipation symptoms were improved significantly in all the 7 patients. The frequency and volume of defecation per week were increased obviously, and the average urine was increased. Six patients underwent permanent implantation of the SNS system. After a median 4 months follow-up, the defecation frequency increased from 0.6 ± 0.5 to 8.0 ± 2.5 per week (P<0.01), and the defecation time decreased from (22.9 ± 11.5) to (3.7 ± 0.8) min (P<0.01). The Cleveland clinic constipation score decreased from 24.6 ± 4.2 to 9.0 ± 0.9 (P<0.01), and the visual analogue scale(VAS) score increased from 8.1 ± 0.9 to 82.5 ± 5.2 (P<0.01).

CONCLUSIONSNM is a clinically efficacious, minimally invasive and safe new technique, which offers an alternative treatment for the patients with intractable constipation resistant to conservative treatment, especially for the patients refractory to traditional operations.

Objective To evaluate the feasibility and safety of tracheal extubation in operating room for patients with end-stage chronic obstructive pulmonary disease (COPD) after single-lung transplantation. Methods Clinical data of 57 recipients who underwent single-lung transplantation due to end-stage COPD were retrospectively analyzed. According to the evaluation indexes of tracheal extubation in operating room established by our hospital, 17 recipients eligible for tracheal extubation in operating room were assigned into the operating room extubation group (OR extubation group) and 40 recipients receiving tracheal extubation in intensive care unit (ICU) were allocated in the ICU extubation group. The evaluation results of intraoperative tracheal extubation and postoperative recovery were compared between two groups. Results Compared with the ICU extubation group, recipients in the OR extubation group had higher oxygenation index, lower arterial partial pressure of carbon dioxide (PaCO₂), lower blood lactic acid level, less fluctuation range of blood pressure and fewer cases receiving extracorporeal membrane oxygenation (ECMO) during operation (all P < 0.05). Two recipients in the OR extubation group received repeated tracheal intubation at 6 and 8 h after returning to ICU, and tracheal extubation at postoperative 6 and 9 d. In the OR extubation group, time of postoperative mechanical ventilation, length of postoperative ICU and hospital stay of the recipients were shorter than those in the ICU extubation group (all P < 0.05). The incidence of grade 3 primary graft dysfunction (PGD), atrial tachyarrhythmia, continuous renal replacement therapy and 1-year survival rate did not significantly differ between two groups (all P > 0.05). Conclusions The tracheal extubation regimen in the operating room for COPD patients after single-lung transplantation established by our hospital is safe and feasible, which shortens the time of postoperative mechanical ventilation, the length of postoperative ICU and hospital stay, whereas does not increase the incidence of postoperative complications.

Objective:To clarify the application value of direct cortical electrical stimulation (DES) in locating vestibular functional cortices and the distribution of vestibular functional cortices.Methods:Implantation of stereo-electroencephalography (SEEG) electrodes was performed in 17 drug-resistant epilepsy patients in our hospital from January 2016 to December 2019. The clinical data of these patients were retrospectively analyzed. DES was performed on these patients and stimulation sites eliciting vestibular symptoms were selected to evaluate accurately anatomic locations of stimulation sites eliciting vestibular symptoms in standard Montreal Neurological Institute (MNI) space, and acquired accurate vestibular functional maps in groups.Results:There were 33 stimulation sites eliciting vestibular symptoms, including 9 sites (28%) located in the supramarginal gyrus, 6 sites (18%) located in the precuneus, 6 sites (18%) located in the posterior insular cortex, 1 site (3%) located in the anterior insular cortex, 4 sites (12%) located in the superior temporal gyrus, 2 sites (6%) located in the middle temporal gyrus, 4 sites (12%) located in the precentral gyrus, and 1 site located in cingulate cortex (3%). Stimulation sites eliciting vestibular symptoms induced by lowest intensity located in the insular cortex (average intensity was 2.43 mA), and the average intensity of 6 stimulation sites located in the posterior insular cortex was 2.17 mA.Conclusion:The functional cortex associated with vestibular symptoms defined by DES sites including the insular cortex, superior temporal gyrus, middle temporal gyrus, superior marginal gyrus, precuneus, precentral gyrus, and cingulate cortex.

Metabolic reprogramming is a common phenomenon in cancer, with aerobic glycolysis being one of its important characteristics. Hypoxia-inducible factor-1α (HIF1Α) is thought to play an important role in aerobic glycolysis. Meanwhile, naringin is a natural flavanone glycoside derived from grapefruits and many other citrus fruits. In this work, we identified glycolytic genes related to HIF1Α by analyzing the colon cancer database. The analysis of extracellular acidification rate and cell function verified the regulatory effects of HIF1Α overexpression on glycolysis, and the proliferation and migration of colon cancer cells. Moreover, naringin was used as an inhibitor of colon cancer cells to illustrate its effect on HIF1Α function. The results showed that the HIF1Α and enolase 2 (ENO2) levels in colon cancer tissues were highly correlated, and their high expression indicated a poor prognosis for colon cancer patients. Mechanistically, HIF1Α directly binds to the DNA promoter region and upregulates the transcription of ENO2; ectopic expression of ENO2 increased aerobic glycolysis in colon cancer cells. Most importantly, we found that the appropriate concentration of naringin inhibited the transcriptional activity of HIF1Α, which in turn decreased aerobic glycolysis in colon cancer cells. Generally, naringin reduces glycolysis in colon cancer cells by reducing the transcriptional activity of HIF1Α and the proliferation and invasion of colon cancer cells. This study helps to elucidate the relationship between colon cancer progression and glucose metabolism, and demonstrates the efficacy of naringin in the treatment of colon cancer.
