Magnetically controlled growing rods have been used to treat early-onset scoliosis for the last 9 years; however, few studies have been published, with only short-term follow-up. The aim of the present study is to systematically review the outcomes of magnetically controlled growing rods in the treatment of early-onset scoliosis with a minimum of 2-year follow-up. Studies were included if patients with early-onset scoliosis (scoliosis diagnosed before 10 years of age) underwent implantation of magnetically controlled growing rods with a minimum of 2-year follow-up. The literature review and data extraction followed the established preferred reporting items for systematic review and meta-analysis guidelines. Data of distraction frequency, number of distractions, distracted length, Cobb angle, kyphosis, T1–T12 length, and T1–S1 length preoperatively, postoperatively, and at final follow-up were collected. Data regarding complications and unplanned reoperations were also extracted. The mean values of these parameters were calculated, or pooled meta-analysis was performed if available. Ten articles were included in this systematic review, with a total of 116 patients and a follow-up period between 23 and 61 months. The mean preoperative Cobb angle and kyphosis angle were 60.1° and 38.0°, respectively, and improved to 35.4° and 26.1° postoperatively. At final follow-up, the Cobb and kyphosis angles were maintained at 36.9° and 36.0°, respectively. The average preoperative T1–T12 and T1–S1 lengths were 180.6 mm and 293.6 mm, respectively, and increased to 198.3 mm and 320.3 mm postoperatively. T1–T12 and T1–S1 lengths were 212.3 mm and 339.3 mm at final follow-up, respectively. The overall rate of patients with complications was 48% (95% confidence interval [CI], 0.38–0.58) and unplanned reoperation 44% (95% CI, 0.33–0.55) after sensitivity analysis. The current evidence from different countries with a minimum of a 2-year follow-up suggests that magnetically controlled growing rods are an effective technique to treat pediatric scoliosis and promote spine growth. However, nearly half of patients still developed complications or required unplanned reoperations.

OBJECTIVE: To investigate the effect of a modified Wuzi Yanzong Pill (, WZYZP) on the male rats' testis after microwave radiation, as well as its potential mechanism. METHODS: Forty-five male rats were randomly assigned to three groups: the control group, the radiation group, and the WZYZP group. The rats in the radiation group and WZYZP group were exposed to microwave radiation for 15 min once, while the rats in the control group were not exposed to any radiation. The rats in the WZYZP group were given a modified of WZYZP by gavage daily for 7 days. Apoptosis in the testis was evaluated using terminal-deoxynucleoitidyl transferase mediated nick end labeling (TUNEL) assay. Histopathological alterations of the testis were observed by haematoxylin-eosin (HE) staining. Tat-interactive protein, 60kD (Tip60) and p53 expressions were determined by Western blotting. RESULTS: The apoptosis index (AI) in the radiation group was higher than that of the WZYZP group and control group on day 1 (D1), day 7 (D7) day 14 (D14) after radiation (P<0.05). The seminiferous tubules were of normal morphology in the control group. In the radiation group, the partial seminiferous tubules were collapsed, basement membranes of the seminiferous epithelia became detached. WZYZP could restore the morphological changes. There was no expression of Tip60 among the three groups on D7 and D14. The expression of p53 was higher in the radiation group than in the control group (P<0.05). WZYZP could down-regulate the rising p53 induced by radiation on D7 and D14 (P<0.05). CONCLUSION A modified WZYZP may affect germ cells, and its protective effects may partly result from its ability to intervene in Tip60 mediated apoptosis.

OBJECTIVE: To investigate the effect and application of warm fluid in patients with proximal femoral nail antirotation(PFNA) internal fixation. METHODS: From November 2012 to December 2016, 80 patients with femoral intertrochanteric fracture were treated with PFNA internal fixation, including 35 males and 45 females, aged from 62 to 90 years old. The patients were divided into two groups. In the control group 40 patients were infused and rinsed at the normal temperature liquid(22 to 24 °C) during the operation; in the experimental group 40 patients were infused and rinsed at warm liquid(36.5 to 37.5 °C). The amount of bleeding, the temperature, the occurrence of shiver and the C-reaction protein in the two groups were analyzed. RESULTS: The incidence of hypothermia and shiver in the experimental group was significantly lower than that in the control group(<0.05). The amount of intraoperative bleeding and C-reaction protein were significantly decreased(<0.05). CONCLUSIONS The application of warm liquid infusion and flushing in PFNA internal fixation can effectively reduce the incidence of hypothermia and shiver, reduce the amount of bleeding in the operation and the infection rate of the surgical site, improve the comfort of the patients, and ensure the safety of the patients.

OBJECTIVE: To investigate clinical effects of minimally-invasive internal fixation for mid-lateral 1/3 clavicle fracture with distal clavicular anatomic locking plate. METHODS: From February 2016 to March 2017, 32 patients with mid-lateral 1/3 clavicle fractures treated by minimally-invasive internal fixation with distal clavicular anatomic locking plate, including 24 males and 8 females with an average of (42.3±12.7) years old (ranged from 22 to 68 years old). According to Robinson classification, 6 patients were type 2A2, 18 patients were type 2B1 and 8 patients were type 2B2. No vessel and nerve injury occurred before operation. The time from injury to operation ranged from 0 to 6 days with an average of (3.1±1.4) days. Length of bilateral clavicule were compared before and after operation to evaluate fracture reduction. Constant score at 6 months after operation was applied to assess recovery of shoulder function. RESULTS: Thirty patients were followed up from 11 to 18 months with an average of (13.3±2.2 ) months. No vessel and nerve injury, implant failure, nonunion or delayed union occurred after operation, and facture wound healed at stage I, the time ranged from 8 to 12 weeks with an average of(10.2±1.1) weeks. Shortened length of clavicle decreased from(11.2±3.6) % before operation to (0.4±0.3)% after operation at 2 days. Ten patients removed internal fixation at 8 months after operation without re-fracture occurred after remove plate. Constant score increased from 23.53±5.21 before operation to 94.30±5.60 after operation at 6 months, and 26 patients got excellent results, and 4 good. Patients were satisfied aesthetic degree of scar and shoulder joint function. CONCLUSIONS Minimally-invasive internal fixation for mid-lateral 1/3 clavicle fracture with distal clavicular anatomic locking plate, which has advantages of less trauma, rapid recover, less scar, could receive good clinical effects and not effect beauty.

OBJECTIVE: To investigate the effects and safety of catgut embedding on alleviating insomnia. METHODS: Totally 510 patients with insomnia were divided into 5 Chinese medicine (CM) syndrome types: Xin (Heart) and Pi (Spleen) deficiency, yin deficiency with excess fire, Xin and gut qi deficiency, Wei (Stomach) disorder, and qi and blood deficiency, respectively. These 5 types of patients were randomly assigned to a catgut embedding group, an acupuncture group or a medication group (30 cases in Xin and Pi deficiency type, Wei disorder type, Xin and gut qi deficiency type, respectively; 40 cases in yin deficiency with excess fire type and qi and blood deficiency type, respectively). In the catgut embedding group, patients were treated by implanting catgut into acupoints once every 10 days for a total of 30 days. In the acupuncture group, patients were treated with acupuncture once per day over 30 days (excluding weekends); and patients in the medication group took 1 mg Eurodin Tablet orally every night for 30 days. Pittsburgh Sleep Quality Index (PSQI) was evaluated before treatment, on 30 and 60 days after the first treatment, respectively. The International Unified Sleep Efficiency Value (IUSEV) was measured at 30 and 60 days. The safety was evaluated after treatment and adverse events were analyzed. RESULTS: The objective PSQI scores including subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbance, daytime dysfunction, and total scores at 30 days were significantly improved compared with pre-treatment in the catgut embedding and acupuncture groups (P<0.01 or P<0.05). At 30 days, the PSQI scores in catgut embedding group were superior to the medication group in the patients with each type of insomnia, with the exception of sleep duration (P<0.01 or P<0.05). At 60 days, significant differences were found between the catgut embedding group and the medication group (P<0.01 for all indices). The IUSEV scores in the catgut embedding group were significantly higher than the acupuncture group at 60 days, and the scores in acupuncture group were higher than the medication group at 30 days (P<0.05 for all types). No severe adverse events were found in this study. CONCLUSIONS Acupoint catgut embedding and acupuncture were more effective than medication in alleviating insomnia syndrome in different Chinese medicine syndrome type. However, the sustained effects of acupoint catgut embedding were superior to acupuncture.

Intermittent hypoxia (IH) has preventive and therapeutic effects on hypertension, myocardial infarction, cerebral ischemia and depression, but its effect on post-traumatic stress disorder (PTSD) has not been known. In this study, we used inescapable electric foot shock combined with context recapture to build PTSD mouse model. The levels of fear and anxiety were valued by the open field, the elevated plus maze (EPM) and the fear conditioning tests; the level of spatial memory was valued by Y maze test; the number of Fos positive neurons in hippocampus, amygdala and medial prefrontal cortex was valued by immunohistochemical staining; and the protein expressions of hypoxia inducible factor-1α (HIF-1α), vascular endothelial growth factor (VEGF) and brain derived neurotrophic factor (BDNF) in these brain area were valued by Western blot. The results showed that IH and model (foot shock) had an interaction on percentage of entering open arms (OE%) in EPM and freezing time and the number of fecal pellets in fear conditioning test. IH increased OE% in EPM and reduced the freezing time and the number of fecal pellets in fear conditioning test in PTSD model mice. At the same time, IH reduced the number of Fos positive neurons in the hippocampus, amygdala and medial prefrontal cortex of PTSD model mice, and increased the protein expression levels of HIF-1α, VEGF and BDNF in these brain tissues. In conclusion, IH pretreatment can relieve fear and anxiety behavior in post-traumatic stress model mice, suggesting that IH may be an effective means of preventing PTSD.

Objective To understand the epidemic situation and the source of infection of the reemerge human rabies in Qinghai. Methods We collected the data on human rabies and the data on the cases of multi- victims bitten by the identical dog, and also the laboratory data of the nucleoprotein ( N) gene of rabies virus from the samples which were detected by reverse transcription-polymerase chain reaction (RT-PCR) and direct immunofluorescence assay (DFA) from 2012 to 2017, to describe the epidemiological characteristics of human rabies and the prevalence of rabies virus in host animals, and to explore the source of infection of reemerge human rabies. Results A total of 7 human cases were reported in 2012-2017 in Qinghai province, among which 1 was bitted by wolf, 2 were bitted by stray dogs, 3 were bitted by domestic dogs which injured by stray dogs or wolfs. A total of 892 canine brain tissue samples were collected, from which 46 positive samples were detected with the positive rate of 5.16% (95% CI：3.70%-6.61%). The positive samples were collected from the nomadic region, which were consistent had the location of the human rabies. The samples collected from the cases of multi-victims bitten by the identical dog/animal had the positive rate of 73.08%, and 4 out of 7 human rabies were exposed to the cases of multi-victims bitten by the identical dog/animal. Genetic sequencing of the rabies virus detected from canine brain tissue samples were belong to China IV lineage, which was closely related to the Arctic clade. Conclusions The reemerging rabies happened in nomadic region of Qinghai province could be a consequence of spillover from wildlife especially from wolfs. The better surveillance system covering the human, livestock and wildlife should be set up to mitigate the rabies virus spread from the wildlife.

Background: As a large, prospective, multicenter study-based prognostic score for hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF), the Chinese group on the study of severe hepatitis B-acute-on-chronic liver failure score (COSSH-ACLFs), has been approved by some foreign scholars; however, its predictive value needs to be verified. This study investigated the predictive value of COSSH-ACLFs for short-term prognosis in Chinese patients with HBV-ACLF. Methods: This retrospective cohort study included 751 patients with HBV-ACLF admitted to the Fifth Medical Center of Chinese PLA General Hospital between January 2011 and December 2014. Spearman method was used to assess the correlation of COSSHACLFs with classical scores. Different COX multivariate regression models were used to confirm the relationship between COSSHACLFs and short-term prognosis in patients with HBV-ACLF, and stratified analysis was used to further verify the stability of this relationship. We compared the predictive powers of COSSH-ACLFs and other classical scores using area under the receiver operating characteristic curve (AUROC) and Z-test. Results: A total of 975 patients with HBV-ACLF were screened, and 751 were analyzed (623 male and 128 female). COSSH-ACLFs was the highest in patients with end-stage ACLF, followed by those with middle- and early-stage ACLF (H = 211.8, P < 0.001). In the fully adjusted model, COX multivariate regression analysis revealed that COSSH-ACLFs (as a continuous variable) was independently and positively correlated with mortality risk in patients with HBV-ACLF at 28 days (hazard ratio [HR]: 1.37 [1.22, 1.53], P < 0.001) and 90 days (HR: 1.43 [1.29, 1.58], P < 0.001). The same trend could be observed in the crude model and minimally adjusted model. The AUROCs of COSSH-ACLFs for 28-day and 90-day prognoses in patients with HBV-ACLF were 0.807 and 0.792, respectively, indicating a stronger predictive accuracy than those of classic models. Conclusions COSSH-ACLFs, with a superior predictive accuracy compared with other classical scores, can strongly predict shortterm prognosis in Chinese patients with HBV-ACLF.
