Objective Face-down positioning after vitrectomy and gas tamponade is still the standard position for patients with rhegmatogenous retinal detachment.The study was to compare the nursing effects of face-down position and flexible position after vitrecto-my for the repair of rhegmatogenous retinal detachment. Methods We investigated 120 cases of patients with rhegmatogenous retinal detachment in this study.All patients received vitrectomy with long-acting gas for tamponade, 60 patients in face-down position and 60 in the flexible position.Patients were followed up for 6 months.Observation was made on the rates of anatomical retinal reattachment and postoperative complications between the groups. Results The rates of anatomical retinal reattachment after surgery were 88.33%in the face-down position group and 100% in the flexible position group respectively.As to the satisfaction of position, the flexible position group was 100%, which was much higher than 41.67%in face-down position group(P<0.01). Conclusion Flexible position nurs-ing after vitrectomy and gas tamponade for rhegmatogenous retinal detachment repair is safe and effective.Flexible position can replace face-down position for the comfort of patients with rhegmatogenous retinal detachment after vitrectomy with gas tamponade.

This study was aimed to collect relevant provisions of bulging disease medical records in the Ming and Qing dynasties to excavate the syndrome differentiation, drug law and medication frequency analysis. A database was established to analyze relevant provisions. The results showed that the syndromes of liver stagnation and spleen deficiency, dampness-heat accumulation, spleen-yang deficiency are the most common type. The mainly used drugs are from the category to eliminate dampness and water, and to tonify the deficiency. The top three used drugs are poria, atractylodes, and dried citrus peel. It was concluded that medications used in the Ming and Qing dynasties were mainly targeted to the disordered zangfu-organ, which was mainly about the spleen and the stomach. The syn-drome differentiation is the mixture of deficiency and excess. And deficiency is the main part. The medication should combine tonification and reducing. And tonification should be paid attention to. The syndrome differentiation and treatment should be coordinated and the primary and secondary aspect should be identified. These rules provide ref-erence effect for the clinical practice and scientific research of bulging disease treatment.

Background: Studies showed that aberrant activation of JAK/STAT3 signaling pathway promoted the tumorigenesis and progression of hepatocellular carcinoma (HCC), and transforming growth factor-β1 (TGF-β1) has either tumor-suppressing or tumor-promoting effect in regulation of tumor progression.Aims: To investigate the effect of specific inhibition of JAK/STAT3 signaling pathway on HCC and whether TGF-β1 signaling pathway is involved in this process or not.Methods: Thirty Wistar rats were randomly divided into three groups: control group, HCC group, and HCC+AG490 group.In the latter two groups, diethylnitrosamine was administered in drinking water to induce HCC model, and in HCC+AG490 group, AG490, a specific inhibitor of JAK was injected intraperitoneally in the first week of model establishment.At the end of the 16th week, all rats were sacrificed.The maximum diameter of tumor nodules in the liver was recorded and the number of tumors with maximum diameter greater than 1 cm was counted.Expression and distribution of STAT3 and TGF-β1 in liver tissue were determined by real-time PCR, immunohistochemistry, and immunofluorescence.Results: Compared with the control group, expressions of STAT3 and TGF-β1 mRNA in liver tissue were significantly increased in HCC group (P<0.05).Phosphorylated STAT3 (p-STAT3) and TGF-β1 proteins were absent in liver tissue in control group, and both were up-regulated and co-expressed in HCC group.While in HCC+AG490 group, expressions of STAT3 and TGF-β1 mRNA were significantly lower than those in HCC group (P<0.05);the liver tissue was weakly positive for p-STAT3 and TGF-β1 proteins, and the number of tumor nodules greater than 1 cm and the maximum diameter were markedly reduced when compared with the HCC group [1.20±1.03 and (1.14±0.18) cm vs.4.30±1.06 and (1.78±0.27) cm, P all<0.05].Conclusions: Specific inhibition of JAK/STAT3 signaling pathway may restrain the tumorigenesis and progression of HCC partially by interfering TGF-β1 signaling pathway.

OBJECTIVETo explore the correlationship between platelet count and efficacy of traditional Chinese medicine (TCM) or Western medicine (WM) in treating rheumatoid arthritis (RA) patients.

METHODSA total of 356 patients with confirmed diagnosis of active RA from 9 clinical centers were randomly assigned to the TCM group (184 cases) and the WM group (172 cases). The TCM group was treated with basic therapy (administration of glucosidorum tripterygll totorum and Yishen Juanbi Pill) and TCM syndrome differentiation dependent treatment, while the WM group was treated with non-steroidal anti-inflammatory drugs and slow-acting anti-rheumatic drugs. The therapeutic efficacy was assessed with ACR20, the joint damage degree of both hands was evaluated by X-ray.

RESULTSThe platelet count was positively correlated to the X- ray grading of joint damage, namely, patients with a more severe joint damage often presented a higher platelet count. After treatment, in patients with joint damage of X-ray grade II or III and effectively treated with TCM, also in patients with joint damage of grade III and effectively treated with WM, the platelet count was lower than that in those treated ineffectively.

CONCLUSIONPlatelet count is closely correlated to the efficacy of drug therapy, therefore, it may be taken as an important index for judging the curative effect of therapeutic approach in treating RA patients.

OBJECTIVETo analyze the rules for acupoint selection of acupuncture and moxibustion in domestic clinical treatment of perimenopausal syndrome based on data mining technology in modern times.

METHODSThe relevant literature were retrieved from Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI) and Wanfang database on this disease treated with clinical acupuncture and moxibustion in China from 1978 to 2013. The database of acupuncture-moxibustion prescription was set up. The relevant regulations of data mining technology were used to analyze the rules for acupoint selection.

RESULTSTotally, 211 papers, 254 acupuncture-moxibustion prescriptions and 130 acupoints were included. The total frequency of acupoints application was 2193 times, with 14 meridians involved. The utilization of the acupoints in the lower limbs and on the back were 33.0% (723/2193) and 23.8% (521/2193) and those of yin and yang meridians were 51.8% (1136/2193) and 44.0% (965/2193), respectively. The utilization of the specific acupoints accounted for 88.7% (1946/2193).

CONCLUSIONIn clinical treatment of perimenopausal syndrome with acupuncture and moxibustion in modern times, the acupoint selection from involved meridians is the basis, associated with multiple methods of acupoint combination; yin and yang meridians are equally important and the specific acupoints are considered particularly critical in application.

A strain, Pseudomonas sp. X-2-45, with high and stable lipolytical activity was screened by continuously subculturing a lipase-producing bacterium P. sp. LP-1 in culture medium containing Jatropha oil as a sole carbon source. Its hydrolytic activity was 29.79 U/mL, which was increased by 288% as compared to that of parent strain. Furthermore, the growth and lipase synthesis of X-2-45, its catalytic ability to hydrolyze vegetable oils, as well as ester synthesis between fatty acids and organic alcohols were studied. Results showed that rates of bacterial growth and lipase synthesis were significantly raised. Bacterial biomass and lipase activity reached the highest level after 30 h of incubation. Moreover, growth stationary period was prolonged and lipase produced exhibited good stability in culture media during incubation period. Hydro- lytic activity of P. sp. X-2-45 lipase toward Jatropha oil was increased by 378% as compared to parent strain, suggesting that acclimation to Jatropha oil was an effective approach for improving substrate selectivity oflipase. Finally, results of ester synthesis catalyzed by P. sp. X-2-45 lipase indicated that this lipase could catalyze esterification reactions between lauric acid and n-butanol, n-octanol, 1-dodecanol or glycerol, palmitic acid or stearic acid and methanol, n-octanol, 1-dodecanol or glycerol, oleic acid and methanol, n-butanol, n-octanol, 1-dodecanol or glycerol.

Results The patients were followed up for 6~24 months,all of 31 ears were primary healing, 26 ears were cured, 4 ears were effective,only one ear was invalid,the effective cure rate was about 96. 8%. Conclusion Local injection with triamcinolone acetonide acetate combined with surgical resection can treat ear keloid.

Objective To retrospectively analyze the cardiac systolic synchrony and cardiac function in patients with chronic heart failure (CHF） by gated SPECT myocardial perfusion imaging (GSMPI). Methods (1) From January 2010 to February 2015, 123 cases including 82 CHF patients (57 males, 25 females, age (59.5±11.0) years) and 41 healthy people (control group; 27 males, 14 females, age (33.8±5.2) years) were enrolled in this retrospective study. According to the New York Heart Association (NYHA) classification, the CHF patients were classified into grade Ⅰ-Ⅳ groups. The systolic synchrony and cardiac functional parameters including PHB, PSD, LVEF, EDV, summed rest scores (SRS) were acquired by Emory Cardiac Toolbox software. Differences of PHB, PSD and LVEF were compared between the CHF group and the control group using two-sample t test. The difference among the four CHF groups was compared by one-way analysis of variance. The difference of some clinical factors was compared between the two groups with and without damage of systolic synchrony. The relationship between the cardiac synchrony and myocardial perfusion was analyzed by Pearson correlation analysis. Results There was no obvious difference of PHB and PSD between the grade Ⅰ CHF patients and the control group (t=-1.502 and -0.448, both P>0.05), while LVEF was significant different (t=10.419, P<0.05). Significant difference of PHB, PSD and LVEF existed between the grade Ⅱ-Ⅳ CHF patients and the control group (t values: from -27.250 to 32.723, all P<0.05). There were significant differences of PHB, PSD and LVEF among the 4 CHF groups (F=118.05, 4.13 and 154.37; all P<0.05). The differences of LVEF, EDV and SRS were significant between the patients with and without damage of systolic synchrony (t=9.57, 10.85, 18.87, all P<0.05). The ratios of damage in systolic synchrony in grade Ⅰ-Ⅳ CHF patients were 8.7% (2/23), 60.0%（12/20）, 15/18 and100% (21/21), respectively. PHB and PSD were both positively correlated with SRS (r=0.808 and 0.773, both P<0.05). Conclusions The damage of systolic synchrony are getting severer from patients with NYHA grade Ⅱ to patients with NYHA grade Ⅳ. The damage could be accompanied by the heart failure progression. Diabetes mellitus, LVEF, EDV, ESV, and SRS are related to the damage. The myocardial perfusion damage is positively correlated with the damage of cardiac systolic synchrony. GSMPI is useful to early diagnosis and treatment of heart failure.
