Ancient Literatures of Classical Famous Prescription Dihuang Yinzi / 中国实验方剂学杂志

Classical famous prescription Dihuang Yinzi is widely used in modern clinical practice，and can treat many kinds of diseases，especially the diseases of nervous system in internal medicine. Its clinical effect is accurate，but it has not been converted into Chinese patent medicine preparations. Therefore，the authors have collected ancient traditional Chinese medicine（TCM） literatures of Dihuang Yinzi by the methods of bibliometrics，and selected and sorted out 254 pieces of effective data， involving 144 ancient books of TCM，and systematically summarized and analyzed the historical development origin，main treatment syndrome，formula making principle，dosage，preparation method，decoction method and medicine taking method of Dihuang Yinzi，in order to provide the ancient literary evidence support for the development and clinical application of classic famous prescriptions. It is found that Dihuang Yinzi was from Xuanming Lunfang written by LIU He-jian，a doctor of Jin dynasty. It was composed of 12 kinds of herbs，namely Rehmanniae Radix Praeparata，Morindae Officinalis Radix，Corni Fructus，Cistanches Herba，Dendrobii Caulis，Aconm Lateralis Radix Praeparaia，Schisandrae Chinensis Fructus，Cinnamomi Ramulus，Poria，maimendong，Acori Calami Rhizoma and Polygalae Radix, and mainly used for the treatment of Yinfei. The later records of Dihuang Yinzi mostly followed the prescription composition and main treatment set forth in Xuanming Lunfang，and its clinical application was expanded. In the 199 articles with the indications for disease treatment，Yinfei was the most commonest indication, and took up about half of the total，which was followed by stroke，taking up about two fifths of the total. It was also used for the treatment of sudden aphonia，flaccidity syndrome，vertigo，enuresis. Dihuang Yinzi has a wide range of treatment，but the pathogenes is always belongs to "the deficiency of water and fire in the kidney". The recipe of Dihuang Yinzi was unique，and can be used to treat both the upper and lower parts of the body，as well as both the outward symptoms and root causes of an illness at the same time， in particular，it mainly focuses on the treatment of the lower and the root. Among the 56 literatures with drug dosage records，about one third of them inherited the records of Xuanming Lunfang: "Equal division，the top is the end，3 qian for each dose." The dosage was generally light. The preparations are mostly decoction and boiled powder. In the decocting and taking methods，it was suggested that "turbid medicine shall be boiled for a short time，and taken after several boilings，with no limit to time."

Clinical effects of pulmonary valve replacement after tetralogy of Fallot repair: A systematic review and meta-analysis / 中国胸心血管外科临床杂志

@#Objective    To evaluate the clinical outcomes of  pulmonary valve replacement (PVR) in patients with tetralogy of Fallot (TOF) after re-PVR surgery. Methods    PubMed, EMbase, the Cochrane Controlled Trials Register databases, CNKI, CBM disc and VIP datebases were searched, and study eligibility and data abstraction were determined independently and in duplicate. Literature searches from database establishment to December 2018. The heterogeneity and data were analyzed by the software of Stata 11.0. Results    Of 4 831 studies identified, 26 studies met eligibility criteria, and invovled with a total of 3 613 patients. The combined 30-day mortality for PVR was 2.2% (95% CI 1.5%-3.1%) and follow-up mortality was 3.4% (95% CI 2.4%-4.9%), re-PVR rate was 6.8% (95% CI 5.1%-9.2%), and the rate of intervention was 11.4% (95% CI 8.0%-16.4%). Subgroup analysis showed that the patient's age range may be a heterogeneous source of mortality during the follow-up period, and there was no statistical heterogeneity for adult patients (P=0.63, I2=0%), with a lower incidence than those including adolescents patients. The type of valve was likely to be a source of retrospective PVR. There was no statistical heterogeneity in bioprosthetic valves and allograft lobes (P=0.24, I2=25%). And the incidence of re-PVR was lower than that of the mechanical valve patients. Heart function classification (NYHA) of patients with TOF after PVR was statistically improved (P<0.05). Electrocardiogram QRS change was not statistically differently (P>0.05). Postoperative MRI findings showed a decrease in RVEDV, an increase in RVEF, a decrease in RV/LV ratio, and a decrease in pulmonary valve (all P<0.05). Funnel map monitoring, Begg test and Egger's test both indicated that there was no publication bias. Conclusions    According to the results of the analysis, PVR after TOF surgery is a more mature surgery, the clinical effect was significant, with lower early and long-term mortality. The long-term mortality rate of adolescent patients undergoing PVR is higher than that of adult patients. Long-term outocme of re-PVR or re-intervention is still the main problem affecting the effect of the operation. Indications for surgery and choice of valve need further investigation.

Clinical effect of circumcision stapler in the treatment of phimosis and redundant prepuce / 中华男科学杂志

<p><b>OBJECTIVE</b>To observe the clinical effect and safety of circumcision stapler in the treatment of phimosis and redundant prepuce.</p><p><b>METHODS</b>We treated 120 patients with redundant prepuce or phimosis using circumcision stapler and another 60 by conventional dorsal-incision circumcision. We observed intraoperative blood loss, operation time, postoperative pain, wound healing time, cosmetic appearance of the penis, and postoperative complications and compared them between the two groups of patients.</p><p><b>RESULTS</b>Stapler circumcision showed obvious advantages over the conventional method in intraoperative blood loss ([2. 3 ± 1. 3] vs [15.6 ± 2.9] ml), operation time ([7.1 ± 1.4] vs [22.6 ± 4.6] min), wound healing time ([12.0 ± 2.9] as [16.3 ± 3. 1] d), postoperative pain score (1. 9 ± 1. 3 vs 5. 2 ± 1. 7), incision edema, and cosmetic appearance of the penis (all P <0. 05). Besides, stapler circumcision exempted the patients from stitch-removal pain. However, the incidence rate of postoperative local ecchymosis was significantly higher in the circumcision stapler group than in the conventional circumcision group (20. 8% vs 8. 3% , P <0. 05).</p><p><b>CONCLUSION</b>Circumcision stapler, with its advantages of easier manipulation, shorter operation time, better cosmetic penile appearance, less pain, and fewer complications, is superior to conventional circumcision in the treatment of phimosis and redundant prepuce.</p>

Effects of antisense p38 α mitogen-activated protein kinase on myocardial cells exposed to hypoxia and burn serum / 中华烧伤杂志

<p><b>OBJECTIVE</b>To study the effects of antisense p38α mitogen-activated protein kinase (hereinafter referred to as p38α) on myocardial cells exposed to hypoxia and burn serum.</p><p><b>METHODS</b>Thirty adult SD rats were inflicted with 40% TBSA full-thickness burn on the back to obtain burn serum. The myocardial cells were isolated from 80 neonatal SD rats and cultured, then they were divided into 4 groups according to the random number table: normal control group (N, ordinary culture without any treatment), hypoxia+burn serum group (HB, exposed to hypoxia after being treated with 10% burn rat serum), hypoxia+burn serum+infection group (HBI, exposed to hypoxia and 10% burn rat serum after being infected with antisense p38α gene-carrying adenovirus), hypoxia+burn serum+empty vector infection group (exposed to hypoxia and 10% burn rat serum after being infected with adenovirus empty vector). At post hypoxia hour (PHH) 1, 3, 6, and 12, mRNA and protein expression levels of p38α in the latter 3 groups were determined by RT-PCR and Western blotting, cell viability was determined by methylthianolyldiphenyl-tetrazolium bromide assay, and lactate dehydrogenase (LDH) activity was assayed at the same time point. At PHH 1, 6, and 12, apoptosis rate of myocardial cells was assessed by annexin V staining method. The indexes of group N were determined with the methods mentioned-above. Three wells were set at each time point in each group. Data were processed with one-way analysis of variance and LSD- t test.</p><p><b>RESULTS</b>(1) At PHH 1, 3, and 6, the p38α mRNA level was higher in group HB than in group N and group HBI (with t values from 2.725 to 4.375, P values all below 0.05). (2) At PHH 1, 3, and 6, the p38α protein level was higher in group HB than those in group N and group HBI (with t values from 5.351 to 7.981, P values all below 0.01). (3) At PHH 3, 6, and 12, the cell viability in group HB (0.115 ± 0.007, 0.104 ± 0.006, 0.094 ± 0.005) was lower than that in group N (0.141 ± 0.014) and group HBI (0.136 ± 0.009, 0.124 ± 0.010, 0.112 ± 0.007, with t values from 2.357 to 6.812, P values all below 0.05). (4) The LDH activity was up-regulated in group HB as compared with that in group N and group HBI at each time point (with t values from 22.753 to 201.273, P values all below 0.01). (5) At PHH 1, 6, and 12, the apoptosis rate of myocardial cells in group HB [(5.4 ± 0.7)%, (8.7 ± 1.1)%, (13.6 ± 1.7)%] was higher than that of group N [(3.1 ± 0.3)%] and group HBI [(4.3 ± 0.5)%, (5.1 ± 0.7)%, (7.2 ± 0.9)%, with t values from 2.345 to 9.700, P < 0.05 or P < 0.01].</p><p><b>CONCLUSIONS</b>Antisense p38α can protect the myocardial cells from the injury of hypoxia and burn serum.</p>

Anatomic basis of the accompanying pattern of the superficial temporal arterial branches and veins and its clinical application / 中华烧伤杂志

<p><b>OBJECTIVE</b>To study the course of branches of the superficial temporal artery (BSTA) and the accompanying pattern of their veins in order to provide anatomic basis for flap design.</p><p><b>METHODS</b>Head and facial part of ten adult corpses (19 sides) were dissected and photographed. The coordinate system was set up with external auditory foramen as the point of origin, aided by the graph analysis software Digimizer. The course of the frontal branch and parietal branch of the superficial temporal artery (STA), and the accompanying pattern between the BSTA and the veins were measured and analyzed. The STA and its branches were located by Ultrasonic Doppler, and the corresponding branches of the superficial temporal vein (BSTV) were disclosed by bowing patient's head with breath holding or cerclaging the basement of the patient's skull. And then 10 sides of transposition (fascia) flaps with axis at the angular bisector between BSTA and BSTV were devised to repair wounds of 9 patients that hospitalized from February 2008 to December 2009. Data were processed with test of variance homogeneity.</p><p><b>RESULTS</b>Frontal BSTV absence was found in 6 head sides, and the maximum distance between artery and vein was (2.1 ± 1.2) cm. Parietal BSTV absence was found in 3 head sides, and the maximum distance was (1.4 ± 0.7) cm. The distance between frontal BSTA and BSTV was larger than that between parietal BSTA and BSTV, and the dispersion degree of the former was higher than that of the latter (F = 0.0404, P = 0.0475). All the (fascia) flaps survived without congestion or necrosis.</p><p><b>CONCLUSIONS</b>When branch of the superficial temporal vessel was selected as the axial vessel of flap, the flap design shall depend on the accompanying pattern of BSTV to avoid the flap necrosis due to poor venous return after surgery. The superficial temporal vein and its branches can be well disclosed by bowing head or cerclaging skull. The approach is simple, useful, safe, and reliable.</p>

Repair of nose and adjacent tissue defect deformities after burn / 中华烧伤杂志

<p><b>OBJECTIVE</b>To look for the best method of repairing nose and adjacent tissue defect after burn and observe the effect.</p><p><b>METHODS</b>Twelve patients with post-burn nose and adjacent tissue defect deformities hospitalized from January 1999 to December 2008 were repaired with expanded forehead flap, pedicled upper-arm flap, axial post-auricular reversed flow island flap, and nasolabial groove flap. Among them, 4 cases with total nasal defect, 8 cases with partial nasal defect; and 3 cases were accompanied with scars on cheek, 5 cases accompanied with scars on forehead, 5 cases accompanied with upper lip ectropion and subtotal upper lip defect. The skin flap size ranged from 3.0 cm x 1.5 cm to 10.0 cm x 8.0 cm.</p><p><b>RESULTS</b>Five cases were repaired with expanded forehead flap, 3 cases with pedicled upper-arm flap, 1 case with axial post-auricular reversed flow island flap, and 3 cases with nasolabial groove flap respectively. All the 12 flaps survived. Patients were followed up for 1 to 7 years, and nasal function and appearance were obviously improved.</p><p><b>CONCLUSIONS</b>Optimal repairing method shall be chosen to repair nasal defect after burn according to its extent, and forehead flap is preferred. Pedicled upper-arm flap and reversed flow axial post-auricular island flap can be employed if local flap and ortho-position skin flap are unavailable when obvious scar is present on face as a result of severe burn.</p>

Pathological experimental study of autologous skin transplant on retained denatured dermis / 中南大学学报(医学版)

OBJECTIVE@#To identify the pathological character of denatured dermis,and its turnover after autologous skin transplant.@*METHODS@#Deep partial thickness burn wounds whose diameter was 2.5 cm were produced on the back of Sprague-Dawley (SD) rats. After simple debriding,xenogenic skin was transplanted. Superficial tangential excision was performed on the burn wounds on 48 hours postburn with the preservation of denatured dermis. Split thickness autologous skin was grafted on the wounds immediately. Tissue samples of whole layer of the skin were harvested from the grafted sites at different time points after the skin grafting. Pathological observation on the denatured skin and the transplanted skin was carried out with HE and Massonos trichrome blue.@*RESULTS@#The superficial cells of the denatured dermis necrotized largely with few cells alive,collagen denatured,and many inflammatory cells infiltrating. Necrosis tissue and inflammatory cells could be found in the denatured skin in the early period after the skin transplant. There were infiltrated inflammatory cells in the transplanted skin 3 days after the skin transplant. On the 10th day,the necrotized tissue diminished markedly,and red cells were found in its upper stratum. On the 21st day, the morphology and structure of the transplanted skin were similar to those of the normal skin.@*CONCLUSION@#The retained denatured dermis has little effect on the survival of the transplanted skin. The necrosis components can be absorbed and replaced by the tissue alive after the autologous skin is transplanted.

Effects of sodium aescinate on bcl-2 and caspase-3 expression and apoptosis after focal cerebral ischemia reperfusion injury in rats / 中南大学学报(医学版)

OBJECTIVE@#To determine the effects of sodiun aescinate on Bcl-2 and Caspase-3 protein expression and neuronal apoptosis after focal cerebral ischemia reperfusion injury in rats.@*METHODS@#One hundred male Wistar rats were subjected to middle cerebral artery occlusion (MCAO) and reperfusion. The rats were divided randomly into 4 groups: sham-operated group and MCAO and reperfusion model groups which were randomly divided into control group, saline group, and sodium aescinate group. The immunohistochemistry staining and microscope image were used to observe the dynamic Bcl-2 and Caspase-3 protein expression in the ischemic penumbra after the reperfusion. Terminal deoxynucleotidyl transferase biotin-dUTP nick end labeling (TUNEL) staining was performed for the detection of apoptosis.@*RESULTS@#Bcl-2 protein expression in the sodium aescinate group was significantly higher than that of the saline group and control group (P < 0.05). While Caspase-3 protein expression in the sodium aescinate group was then compared with those of the saline group and control group, and showed the difference was significant (P < 0.05). Compared with the saline group and control group, the number of apoptotic cells in the sodium aescinate group was significantly reduced (P < 0.01).@*CONCLUSION@#Sodium aescinate increases Bcl-2 protein expression and decreases Caspase-3 protein expression,through which it can protect the ischemia brain on reperfusion injury.
