Objective To observe the effect of electroacupuncture(EA) on the hippocampal expression of GluA1,pGluA1,CaMK Ⅱ and pCaMK Ⅱ in rats with vascular dementia(VD),so as to find out the underlying mo lecular mechanisms of EA in treating VD.Methods Thirty-two Wistar rats were randomly divided into a shamoperation group,a model group,a sham-acupuncture group,and an EA group (8 in each group).Permanent bilateral common carotid artery occlusion was performed to model vascular dementia in the model group,the shamacupuncture group and the EA group,while exposure but no occlusion of the bilateral common carotid were performed in the sham-operating group.Novel object recognition test was adopted to prove the establishment of VD rat model.All the rats were kept in an immobilization apparatus while receiving treatments.EA was applied ontoBaihui (GV20) and Zusanli (ST36) in EA group for 30 min,once daily for 7 days.Sham-acupuncture group were treated with needles inserted 0.5 mm superficially.And the sham-operation group and the model group were only immobilized.The protein expression of GluA1,pGluA1,CaMK Ⅱ and pCaMK Ⅱ in hippocampal tissue was detected by western blotting.Results The expression of GluA1 in the model group (1.216 ± 0.102) was significantly less than in the sham-operating group (1.918 ± 0.137) (P ＜ 0.05).The expression of GluA1 in the EA group (1.653 ± 0.169) was significantly higher than in the model group (1.216 ± 0.102) and in sham-acupuncture group (1.231 ±0.188) (P＜0.05).The expression of CaMKⅡ in the model group (1.516±0.392) was less than in the sham-operating group (2.187 ± 0.231) (P ＜ 0.05).The expression of CaMK Ⅱ in the EA group (2.733 ±0.387) was significantly higher than in the model group (1.516 ±0.392) and sham-acupuncture group (1.493 ±0.205) (P＜0.05).The expression ofpGluA1 in the model group (1.502 ±0.419) was less than in the sham-operating group (2.253 ± 0.244) (P ＜ 0.05).The expression of pGluA1 in the EA group (2.382 ± 0.308) was significantly higher than in the model group (1.502 ± 0.419) and the sham-acupuncture group (1.498 ± 0.223) (P ＜ 0.05).The expression of pCaMK Ⅱ in the model group (0.394 ± 0.227) was less than in the sham-operating group (0.667 ±0.175) (P＜0.05).The expression ofpCaMKⅡ in the EA group (1.189± 0.346) was significantly higher than in the model group (0.394 ± 0.227) and the sham-acupuncture group (0.408 ± 0.231) (P ＜ 0.05).Conclusion EA can enhance the protein expression and phosporylation of GluA1 and CaMK Ⅱ,causing silent synapses transforming into functional synapses,and consequently,long term potentiation was facilitated and cognitive impairment was improved by EA.

AIM To explore the radioprotective function of Xihuang Capsules (Bovis Calculus artijactus,Moschus,Olibanum,Myrrha) in patients with acute radiation-induced oral mucositis and its mechanisms.METHODS Eighty patients with nasopharyngeal carcinoma undergone radiotherapy were randomized into two groups:treatment group (radiation plus Xihuang Capsules) and control group (radiation alone).The comparison of two groups in the onset and the tolerated dose of mucositis was made according to the acute radiation injury classification standard.The levels of TNF-α and IL-6 in saliva were detected by ELISA.RESULTS After the treatment with Xihuang Capsules,the onset of oral mucositis delayed significantly and the tolerated dose elevated markedly comparing with the control group (t =2.180,12.930,P ＜ 0.05).The morbidity rate of Ⅲ-N-degree of oral mucositis in the treatment group was lower than that of the control group at the dosage of 40 Gy and 70 Gy,respectively (Z =3.661,4.270,P ＜0.01).Furthermore,there was no difference in the levels of TNF-α and IL-6 in the pre-treatment in the two groups (t =1.010,1.469,P ＞ 0.05).With the increase in radiant dose,the levels of TNF-α and IL-6 in the two groups both elevated dramatically,and peaked at the dose of 40 Gy,but both levels in the treatment group were lower than those of the control group (t =8.305,6.069,P ＜ 0.05).When DT =70 Gy,the levels of TNF-α and IL-6 were lower than pre-radiation,and the levels of TNF-α and IL-6 in the treatment group were lower than those in the radiation alone group (t =3.835,2.488,P ＜ 0.05).CONCLUSION Xihuang Capsules can delay and reduce acute radiation-induced oral mucositis and improve radiation tolerated dose,so it may involve the release of TNF-oα and IL-6 in saliva.

Objective This research is proposed to improve the recognition of the clinical features, therapy and prognosis of palindromic rheumatism.Methods We analyzed the clinical data of 63 palindromic rheumatism patients.Their response to therapy was observed,and they were followed up for 1.5 to 3 years. Results The average onset age of the patients was(40?11)years and the average disease duration was(8?7) years.They were characterized by recurrent attacks of sudden-onset acute arthritis and(or)periarticular tis- sue inflammation,in which most joints were involved.In 46 percent of the patients,the attacks were incited by some events.In 67 percent of them,the attacks recurred more and more frequently.Nonsteroidal anti-in- flammatory drugs and disease modifying anti-rheumatic drugs(DMARDs)was effeeive in variant extents,to palindromic rheumatism patients.Five percent of patients achieved complete remission.Nine percent of them had relapses for a long time.And 5% of them evolved to RA.Conclusion Palindromic rheumatism is a syn- drome characterized by recurrent attacks of sudden-onset acute arthritis and(or)periarticular tissue inflam- mation.The therapy of DMARDs,especially penicillamine and chloroquine diphosphate,is effective on the syndrome.The outcomes of palindromic rheumatism is diverse.

Panax ginseng is the king of herbs and plays important roles in the traditional Chinese medicine industry. In this paper, we summarized the development of ginseng cultivation in China and other main countries, analyzed the effects of ecological factors of soil and climate on ginseng distribution, and investigated the characteristic of main cultivation patterns (conversion of forest to cultivate ginseng soils, cultivated ginseng in the farmland and wild nursery). Aimed at the serious issues in the cultivation, research strategies have been provided to guarantee the sustainable development of the ginseng industry. The patterns of cultivated ginseng in the farmland should be strive to develop; pollution-free cultivation and studies of continuous cropping obstacles should be carried out; ginseng varieties suited to ecological environment of farmland should be bred using modern biotechnology.

AIM: To observe effect of the iris location to femtosecond - combined wavefront guided LASIK for myopia and astigmatism.?METHODS:The patients with astigmatism >1. 0D during the same time and followed up for 1a were selected. A total of 129 eyes in 67 patients were treated under iris location with femtosecond-combined wavefront guided LASIK ( experimental group) and 161 eyes in 82 cases with femtosecond-combined wavefront guided LASIK ( control group) . Laser cutting went with the same laser machine. The uncorrected visual acuity ( UCVA ) , best corrected visual acuity ( BCVA) , and wavefront aberration between the two groups were compared at 1, 3, 6mo and 1a after surgery.?RESULTS:At 1 and 3mo after surgery, the number of patients with better postoperative UCVA than preoperative BCVA between the two group showed a statistically significant difference (χ2=6. 423, P=0. 011,χ2=14. 431, P=0. 01 ); at 1d and 1mo after surgery, the residual astigmatism showed a statistically significant difference between two groups (t=1. 98, P<0. 05; t=2. 23, P<0. 05). At 3, 6mo and 1a after surgery, the differences on the change of residual astigmatism between the two groups weren’t significant ( P > 0. 05 ). At 6mo and 1a after surgery, the differences on UCVA between the two groups weren’t significant ( P > 0. 05 ). Until 1a after surgery, the root mean square ( RMS ) of high order wavefront aberration of the two groups, spherical aberration and coma aberration ( COMA ) were all enhanced compared to before surgery(P<0. 05). At 1, 3mo after surgery, the RMS showed a statistically significant difference between two groups (P<0. 05). At 1, 3, 6mo, 1a after surgery, the increase of COMA in experimental group was significantly lower than that in control group (P<0. 05).? CONCLUSION: Iris location technology applied in femtosecond - combined wavefront guided LASIK for myopia and astigmatism, can make the vision recovery faster, the RMS of high order and COMA increase less, the residual astigmatism less, show better and more stable treatment effect.

AIM:To contrast analysis of postoperative variation of corneal posterior surface heights after Femtosecond LASlK ( FS - LASlK ) and small incision lenticule extraction ( SMlLE) for high myopia.
●METHODS: Sixty-seven cases of high myopic patients (132 eyes) operated with laser corneal refractive in our hospital from May to Dec. in 2015 (-6. 00D≤spherical equivalent degree≤-10. 00D) were selected and divided into FS-LASlK group and SMlLE group. The thickness of corneal flaps at FS-LASlK and the thickness of map at SMlLE were designed to be 110μm. Corneal posterior surface heights were examined by Pentacam at preoperation, postoperative 3 and 6mo after FS-LASlK and SMlLE operation. Surface height changes after preoperative, postoperative 3 and 6mo were compared by measuring Pentacam corneal analysis system.
●RESULTS: Six months after operation, the FS-LASlK posterior corneal surface height was 6. 47 ± 1. 65mm, significantly higher than 5. 20 ± 1. 32mm before operation. SMlLE posterior corneal surface height was 6. 40 ± 1. 33mm, significantly higher than 5. 18 ± 1. 25mm before operation, the differences were statistically significant( P<0. 05). Six month after surgery, two methods of corneal surface height variation obtained was 1. 29 ± 1. 28mm and 1. 22 ± 0. 89mm, there was no significant difference ( P>0. 05).
●CONCLUSION:After FS-LASlK and SMlLE, the corneal posterior surface is protrusive. FS - LASlK is slightly obvious than SMlLE in early period. The stability of the posterior surface is better after SMlLE.

Objective To explore the clinical value and typing characteristic of prenatal ultrasonography for fetal cystic adenomatoid malformation of the lung(CAML).Methods Ultrasonographic features and typing of fetal CAML in 41 cases detected by prenatal ultrasonography were analyzed retrospectively.All cases were followed up until to the induction of labor or birth.Results (1)Site of tumor: in the 41 cases,there were 22 cases on the left side,15 on the right side and 4 on bilateral.(2)Typing diagnosis of prenatal ultrasonography: three cases were CAML type Ⅰ,14 were type Ⅱ,and 24 cases were type Ⅲ.(3)Pathology diagnosis: thirty two cases were induced abortion.CAML was confirmed in 29 cases by autopsy and the classifications were consistent with the prenatal diagnosis of ultrasonography.Three pulmonary sequestration cases were prenatally misdiagnosed as CAML type Ⅲ by ultrasonography.(4)The other nine cases were followed up to birth.Three masses decreased gradually and then disappeared.Six newborns were confirmed as CAML by CT.Their typings were consistent with the postnatal diagnosis.(5)The diagnostic accuracy rate of prenatal ultrasonography for CAML was 92.7%(38/41).Its misdiagnostic rate was 7.3%(3/41).Conclusions Prenatal ultrasonography has a high accuracy rate for the diagnosis and classification of CAML and is the first choice to detect CAML early in pregnancy.It has an important clinical value.Pulmonary sequestration should be distinguished from CAML type Ⅲ because they tend to be confused.
