Objective To investigate the effect of early rehabilitation on serum matrix metalloproteinases (MMP) in patients with traumatic brain injury. Methods Patients with traumatic brain injury were divided into control group (n=45), who accepted routine treatment, and observation group (n=45), who accepted early rehabilitation in addition. The incidences of improvement were compared, and the serum level of MMP-2 and MMP-9 were measured before and 4 weeks after treatment. Results The incidence of improvement was more in the observation group than in the control group (P<0.01). The serum level of MMP-2 and MMP-9 decreased more in the observation group than in the control gorup (P<0.05). Conclusion Early rehabilitation can reduce the level of MMP and promote the function recovery in patients with traumatic brain injury.

Objective To find out the classification of diseases contracted by patients of the emergency department.Methods A retrospective investigation and analysis was made of the medical records of 82 598 emergency cases in our hospital. Results Injury and poisoning, respiratory disease, and disease of digestive system were the first three kinds of disease treated by the emergency department; male emergency cases outnumbered female ones; the volume and visiting hours of emergency cases in a typical day take the shape of humps, with 19 to 21 hours being the climax; the ages of emergency cases averaged 41.5, with patients of the age group running from 19 to 35 being the largest in number in 16 kinds of disease. Conclusion ①It is imperative to determine the priorities of technology construction and the orientation of talent cultivation in the emergency department according to the disease spectrum of emergency cases. ②It is necessary to attach importance to the education of males in health, safely and precautions. ③It is essential to fully recognize the great significance that enhancement of the expertise of the emergency department carries with regard to the health of the population. ④It is important to rationally plan work in accordance with the rush hours of emergency cases's visits.

Result The curative compliance of the experiment group after follow-ups was significantly better than that of the control group (P<0.01).Conclusion The telephone follow-ups can significantly improve the curative compliance of syphilis patients,which can significantly prevent the spread of syphilis.

Objective To prepare the solid dispersion of ginsenoside Rg3 with different carriers and measure their solubility and dissolution characterisitics. Methods The solid dispersion of ginsenoside Rg3 was prepared by the melted and dissolved methods with Poloxamer 188(F68), PVP k29/32, and PEG 6000 as carriers, respectively. The equilibrium solubility and dissolution characteristics of the solid dispersion in vitro were measured by HPLC. The existing state of ginsenoside Rg3 in the solid dispersion was identified by the differential scanning calorimetery. Results The ginsenoside Rg3 was completely dispersed in carrier and formed a mixture with carriers. The solubility and dissolution rates of all solid dispersion were increased obviously. Conclusion The solid dispersion of ginsenoside Rg3 with Poloxamer 188 as carriers is better on improving dissolution and solubility than those with PVP and PEG 6000 as carriers.

Objective To study the influence of sole massage on children’s analepsia from general anesthesia.Methods One hundred children in analepsia period were divided into the test group(50 cases)and the control group(50 cases).The routine nursing and monitoring during recovery stage were done in the control group.Based on the routine monitoring and nursing care as in the control group,the test group received sole massage for 10 minutes.The two groups were compared in terms of declining percentage of SpO2, rate of nausea,blood pressure,heart-rate variability,and post-analepsia dysphoria scores.Result The test group was significantly lower than the control one in all the indexes of the declining percentage of SpO2,rate of nausea,blood pressure,heart-rate variability,and post-analepsia dysphoria scores(all P<0.05).Conclusions Sole massage during children’s analepsia from general anesthesia is effective not only in lessening their declining percentage of SpO2,rate of nausea,blood pressure,heart-rate variability, and recovery dysphoria mark,but also easing their dysphoria,anxiety and fear.It may create a good condition for children to live through analepsia period successfully and safely.

AIM:To investigate the effects of pioglitazone on the quantity and function-related factors of regu-latory and effector T cells ( Treg and Teff ) of uremic apolipoprotein E knockout mice in vitro with or without the stimulation of atherosclerotic plaque-specific antigen oxidized low-density lipoprotein ( oxLDL) .METHODS:Uremic apolipoprotein E knockout mouse model was established by 2-step surgical procedure.After intervention with different concentrations ( 2μmol/L and 20μmol/L) of pioglitazone and PPARγantagonist GW9662 (5μmol/L) on splenocytes of uremic mice for 12 h in the presence or absence of oxLDL (2 mg/L), the levels of CD4 +CD25 +Foxp3 +Treg and IFNγ+CD4 +Teff were de-termined by flow cytometry.The mRNA expressions of Foxp3 and IFNγwas detected by real-time fluorescent quantitative PCR.RESULTS:In vitro, oxLDL induced a Treg/Teff imbalance in splenocytes from the uremic mice.Pioglitazone up-regulated the level of Treg and mRNA expression of Foxp3 in the presence of oxLDL, which was not antagonized by GW9662.Meanwhile, pioglitazone downregulated the level of Teff and mRNA expression of IFNγin the presence or ab-sence of oxLDL, which was reversed by GW9662.CONCLUSION:oxLDL induces a Treg/Teff imbalance in uremic apo-lipoprotein E knockout mice.Pioglitazone modulates the Treg/Teff imbalance probably through PPARγ-independent and-dependent mechanisms.

Objective:To evaluate the vital signs changes,influence factors in different grades of hy-pertension patients during the treatment of acute pulpitis,in order to obtain the risk prevention measures. Methods:In this study,90 different grades of hypertension patients with acute pulpitis were recruited from February 201 4 to February 201 5 in the Department of Oral Emergency,Peking University School and Hospital of Stomatology.The information about the patients’general health,oral treatment,life signs of change information was collected.Patients were divided into high risk group,middle risk group, and low risk group (30 patients for each group).Results:(1 )Compared with the preoperative,systolic blood pressure (90%),diastolic blood pressure (80%),heart rate increase (1 00%)were increased in the high risk group.The increase rates of the middle risk group and the low risk group were significantly lower than those of the high risk group (P<0.01 ).At the same time,the systolic blood pressure of 1 /4 (26.7%)patients in high risk group increased more than 20 mmHg (1 mmHg=0.1 33 kPa),and the diastolic blood pressure of 2/5 patients in high risk group increased more than 1 0 mmHg,the difference was statistically significant compared with the other two groups (P<0.05).(2)Compared with the pre-operative,the average increase of the maximum peak were increased [systolic blood pressure (1 8.0 ± 1 .5)mmHg,diastolic blood pressure (8.0 ±1 .7)mmHg],the mean of heart rate changes [(7.0 ± 0.3)beats per minute]was also increased in the high risk group,while these two indicators were de-creased in the low risk group and the middle risk group.The electrocardiogram (ECG)was changed in 6 cases during the treatment in the high risk group.No significantly changed were observed in the low risk group and the middle risk group.(3 ) Compared the risk assessment in preoperative with that in postoperative,in the middle risk group,23 cases were evaluated as medium risk in final evaluation,6 as low risk,and 1 as high risk (risk assessment increased);in the high risk group,20 cases were evaluated as high risk,7 as very high risk,and 3 as medium risk (risk assessment decreased).Conclusion:Oral treatment is very safe for patients with hypertension,but the risk factor,target organ damage,and com-plications will also increase the risk of cardiovascular events in elderly patients during the acute pulpitis treatment.Dentist should take some measures to avoid the risks.

Objective: To observe the clinical efficacy of electroacupuncture (EA) on Alzheimer's disease (AD). Methods: A total of 50 AD patients were randomly allocated into a Western medication (WM) group (n=25) and an acupuncture plus medication (APM) group (n=25). Patients in the WM group took oral huperzine A capsules. In addition to huperzine A capsules, patients in the APM group also received EA at Shenting (GV 24), Baihui (GV 20), Dazhui (GV 14), Fengfu (GV 16), Mingmen (GV 4) and Yongquan (KI 1). The needles on the above points were connected to G6805-Ⅱelectric stimulator [3 pairs: Shenting (GV 24) and Baihui (GV 20); Dazhui (GV 14) and Fengfu (GV 16); and bilateral Yongquan (KI 1)]. The needles were retained 25 min. The treatment was done once a day, and 10 times made up a course of treatment. The patients received a total of 3 treatment courses. There was a 3-day interval between two courses. The mini-mental state examination (MMSE) and Hasegawa dementia scale revised (HDS-R) were conducted before and after treatment. The clinical efficacies were evaluated when the treatment was completed. Results: Before treatment, there were no between-group statistical differences in MMSE and HDS-R scores (both P>0.05). After treatment, the MMSE and HDS-R scores in the APM group were significantly higher than those in the WM group (both P<0.05). The total effective rate in the APM group was 88.0%, versus 76.0% in the WM group, showing a statistical difference (P<0.05). Conclusion: EA is effective for AD and can improve clinical symptoms in AD patients.
