Objectives To observe the effect of Suanzaoren Decoction on the expression of NMDAR1, NMDAR2A and NMDAR2B RNA in cortex and hippocampus of depression model rats, and explore the mechanism of treating depression. Methods Ninty SD rats were randomly divided into blank group, model group, western medicine group, Suanzaoren Decoction high, medium and low dose group. Except the blank group, the other groups were replicated the rat model of depression in chronic stress. The treatment groups were given corresponding drugs by gavage. The expression of NMDAR1, NMDAR2A and NMDAR2B genes in cortex and hippocampus were detected by RT-PCR. Results Compared with the model group, the positive expression of NMDAR in cortex and hippocampus decreased in Suanzaoren Decoction high and medium dose group (P<0.01). The positive expression of NMDAR2A in cortex and hippocampus of Suanzaoren Decoction high, medium dose group and western medicine group decreased (P<0.05, P<0.01), the expression of NMDAR2A in hippocampus increased in Suanzaoren Decoction low dose group (P<0.05). The positive expression of NMDAR2B in cortex decreased in western medicine group, Suanzaoren Decoction high, medium and low dose group (P<0.01). The expression of NMDAR2B in hippocampus increased in Suanzaoren Decoction medium and low dose group (P<0.01). Conclusion Suanzaoren Decoction can play the role of treating depression by decreasing the expression of NMDAR1, NMDAR2A and NMDAR2B RNA in cortex and hippocampus.

Objective To investigate the effect of Suanzaoren Decoction on hippocampus, cortex BDNF and TrKB gene expression in depression model rats. Methods Depression rat models were established by social-isolated raise and chronic stress stimulation. Suanzaoren decoction was administrated to the models. RT-PCR was adopted to detect the expression of mRNA BDNF and TrKB genes. Results The mRNA expression of BDNF and TrKB in cortex of Suanzaoren decoction high dose group、medium dose group and clomipramine group(0.213±0.094, 0.639±0.023, 1.032±0.015, 1.089±0.014, 1.580±0.012, 1.860±0.019)were all higher than the model group(0.032±0.008, 0.001±0.000), showing a significant difference among four groups (P<0.01), and the mRNA expression of BDNF and TrKB in hippocampus of Suanzaoren decoction high dose group, medium dose group and clomipramine group(0.213±0.094, 0.639±0.023, 1.032±0.015, 1.089±0.014, 1.580± 0.012, 1.860±0.019)were higher than the model group (0.021±0.015, 0.125±0.013), there was a significant difference between four groups(P<0.01). Compared with the model group, the mRNA expression of low-dose group of Suanzaoren decoction in both cortex and hippocampus of BDNF and TrKB was not significantly different to the model group(P>0.05). Conclusion Suanzaoren decoction can increase the expression of BDNF and TrKB gene, promote neuronal proliferation, and resist depression.

Purpose To implement lower artery angiography in patients with peripheral arterial occlusive disease, and to investigate the feasibility of lower extremity gemstone spectral CT angiography in improving image quality.Materials and Methods Forty-eight patients suspected with lower extremity arterial occlusive diseases were randomly divided into research group and control group. Research group (24 cases) were carried out gemstone spectral CT angiography (CTA) scan and control group (24 cases) were scanned with multi-slice spiral CT (CTA). The CT value of the common iliac artery, popliteal artery and its branches was measured and contrast to noise ratio (CNR) were calculated in both groups. The images were evaluated independently by 2 senior physicians based on a 5-level evaluation standard.Results The CT value of common iliac artery, popliteal artery, anterior tibial artery and the CNR in research group were all higher than those in control group (t=8.7, 7.9, 12.6 and 17.2,P<0.01), but the background noise was lower than that in control group (t=1.5,P<0.01). The scores of two image quality accessed by physician 1 and 2 were 110:90 and 111:93 respectively with statistical difference (Z=-7.6 and-8.0, P<0.01).Conclusion The image obtained by gemstone spectral CT optimal single energy image technique is much better than that by conventional multi-slice spiral CT in lower extremity angiography.

Objective To probe the definition of cicateicial cryptotia and its plastic and reconstructive surgery.Methods Local skin flaps combined with full-thickness skin graft by zonation grafting technique were used to treat twenty-six patients with thirty-three cicateicial cryptotia.A cicateicial adhesion between auricle and cranial wall and mastoidea was removed,cranioaural angle was reformed,and helix and auricular lobule were reconstructed.Results All skin flaps survived,and the survival rate of skin grafts reached over 95 ％.The appearance of auricle was very good,its major constructions might be noted,and cranioaural angle nearly returned to normal.The follow-up results from three months to one year post-operation showed that the appearance of auricle kept well,and the patients felt satisfactory.Conclusions In view of deformity characteristics of cicateicial cryptotia,it might be an effective approach to treat cicateicial cryptotia to take a seris of appropriate surgical procedures.

Objective To study the application of suture and ligature and swelling technique in the removal of giant skin benign tumor in none-extremity position.Methods The swelling technique was merely used in those whose lesions were located on face and neck before operation.If the lesions were located on scalp or truck,suture and ligature and swelling technique would be combined in the treatment.Firstly,the lesion was sutured and ligated one or two circles all around.Then swelling fluid was injected under lesion,and incision was done inside or between sutures.Results The area of lesion once excised was 154.00-2394.75 cm2,and the quantity of swelling fluid was 150 1950 ml.The longest time to suture and to ligate the lesion was one hour,and operative bleeding was obviously decreased.Conclusions Suture,ligature and swelling technique might be helpful to decrease operative bleeding during excision of giant skin benign tumor in none-extremity position,and therefore increase operative safety.

Objective To summarize the experience of emergency treatment and cosmetic repair of facial trauma.Methods The clinical materials of 584 wounds from 291 cases of facial trauma,recruited in hospital from January 2010 to August 2012,were summed up retrospectively.The principles of medical aesthetics and plastic and cosmetic surgery were followed.A high pressure douching technique was employed to carry out thorough debridement,but occasion of the debridement did not emphasize with intensive attention.A wound without skin and soft tissue defect was sutured accurately according to tissue zonation with a new suture technique,and the needle distance or side distance was limited in 0.2 cm to 0.3 cm.Otherwise,the wound was repaired by full-thickness skin graft or various flaps according to the repair principle ofrather near than further,rather simple than complicated.Attention was paid to rehabilitation care.Results After debridement,328 wounds were sutured directly,147 wounds were repaired by full-thickness skin grafting and 109 wounds by various flaps.A total of 571 wounds healed on the first stage,and the healing rate reached 97.8％.The wounds were in satisfactory apposition and without obvious cicatrix.Five senses did not appear in malposition and deformity.The other 13 wounds did not heal because of bad taking of skin grafts and flaps or wound splitting.Among them,4 wounds were repaired by second operation,and 9 wounds healed by changing dressings.By means of rehabilitation care,scar hyperplasia and pigmentation appeared slightly in those 13 wounds.A total of 454 wounds from 217 cases were followed up.The results showed good appearance and slight cicatrix hyperplasia,a pigmentation in different degree appeared in 11 wounds covered by skin grafting.In addition,eyebrow excalation,auricle excalation or total lose appeared in 12 cases.Conclusion During treating emergency cases of facial injuries,if an idea cosmetic repair of traumais followed,the theory of aesthetics and the techniques of plastic and cosmetic surgery are fully used,a multiple-discipline cooperation is brought into full play,and a prompt and accurate treatment is put into practice,the aim of cosmetic repair would come true.

Objective: To investigate the effect of Ethephon on the testis pathological structure and apoptosis of spermatogenic cell in offspring male rats. Methods: Twenty-four healthy female SD rats of 45 days old were randomly divided into control group, low-dose Ethephon group, medium-dose Ethephon group and high-dose Ethephon group according to body weight.The male rats of the same age were selected to mate with female rats.The rats were fed with Ethephon solution of different concentrations or 9 g/L saline every day, and they were continued to be fed with Ethephon during pregnancy and lactation.At the age of 7 days and 14 days, 10 offspring male rats were randomly selec-ted from each group and were put to death.The testicular tissue was stained with HE, and the morphological changes in the testis were observed with light microscope; the apoptotic cells were labeled with terminal deoxynucleotidyl transfe-rase dUTP nick-end labeling (TUNEL method) and the apoptosis index(AI) of testis spermatogenic cells was detected with fluorescence microscope. Results: At the age of 7 days, the testis internal structure of the control group developed well, and the spermatic tubules were neatly and compactly arranged.In the low-dose Ethephon group, the seminiferous tubules of the testis were slightly smaller and the spermatogenic cells were loosely arranged compared with the control group.In the medium-dose Ethephon group, the testis seminiferous tubules were slightly disordered and the cell gap increased.In the high-dose Ethephon group, the testis development was poor, the diameter of seminiferous tubules decreased significantly, and the spermatogenic cells arrangement was in disorder.There was no statistically significant difference in spermatogenic cell AI between the low-dose group [(0.54±0.10)%] and the control group[(0.53±0.09)%] (P>0.05), while the spermatogenic cell AI in the medium-dose Ethephon group [(0.63±0.11)%] and the high-dose Ethephon group [(0.81±0.06)%] were higher than that in the control group, thus there exists a statistically significant difference (all P<0.01). The spermatogenic cell AI in the low-dose Ethephon group [(0.54±0.10)%] was lower than that in the medium-dose Ethephon group [(0.63±0.11)%], and the difference was statistically significant (P<0.05). The spermatogenic cell AI in the medium-dose Ethephon group was higher than that in the high-dose Ethephon group, and the difference was statistically significant (P<0.01). At the age of 14 days, the spermatogenic cells AI in control group, low-dose Ethephon group, medium-dose Ethephon group and high-dose Ethephon group were (0.54±0.08)%, (0.65±0.11)%, (0.77±0.11)%, and (0.88±0.10)% respectively, and the spermatogenic cells AI in all groups increased gradually, in which the differences were statistically significant (all P<0.01). Conclusions Excessive dose of Ethephon can induce pathological changes in testicular tissue and increase the apoptosis of spermatogenic cells, resulting in low fertility of offspring rats.

Objective To explore the clinical effect of negative pressure suction combined with washing by Chinese herbal bath to treat small penis in obese children at school age.Methods The data of 60 obese cases with small penis at the First Affiliated Hospital of Xinxiang Medical University from June 2016 to September 2017 were retrospectively analyzed,the age ranged from 7 to 15 years old,and the average age was (11.1 ± 2.0) years old,the body mass index(BMI) was 19.2-30.5,and the average BMI was 24.5 ± 2.6.Treatment group received the penis treatment with negative pressure instrument suction supplemented by traditional Chinese medicine bath treatment,once a day,20 minutes each times,10 days asa course,a totally of 2 treatment courses.Other 46 cases of male children who came to our hospital in the same period for physical exam were selected as healthy control group,aged 8-14 years old [(11.2 ± 2.1) years],BMI:14.6-21.0,mean 18.1 ± 1.6,and the relaxation length and elongation of 20 days before and after the normal growth state of the penis in the control group were measured.The length and elongation of the penis in the treatment group were compared with those of the healthy control group before and after treatment.Results The length of penile relaxation in the treatment group increased to (3.76 ±0.61) cm in comparison with that before treatment (2.94 ± 0.52) cm,and the difference was statistically significant (t =-7.82,P ＜ 0.05);the penis elongation increased compared with that before treatment (4.29 ± 0.67) cm to (5.37 ± 0.82) cm,and the difference was statistically significant (t =-7.91,P ＜ 0.05).The initial relaxation length of the control group was (3.96 ± 0.65) cm,(4.07 ± 0.65) cm 20 days after natural growth,the difference was not statistically significant (t =-0.82,P ＞ 0.05),the initial stretch length was (5.96 ± 0.92) cm,(6.03 ± 0.90) cm natural growth after 20 days,and the difference was not statistically significant (t =-0.37,P ＞ 0.05).Before and after treatment,the length of penis relaxation and elongation were significantly increased,but they didn't reach the normal level at the same age.Conclusions Negative pressure suction supplemented with Chinese herbal medicine bath has a significant effect on treating obese children with small penis.

OBJECTIVETo explore the timing and suitable method of reconstructing penile defects caused by devastating electrical burn.

METHODSThirteen patients with penile defects after devastating electrical burn, hospitalized from September 1998 to August 2013, were included in this study. After the necrotic tissues in the wounds were removed by dressing changes, a local or a hinge-like flap constructed from scrotum or abdominal wall, a prelaminated hinge-like flap from forearm, or a free forearm flap was selected, according to the injury degree of the penis, for the repair of the defect or reconstruction of penis respectively.

RESULTSThe flaps survived and the wounds healed well in 2 patients repaired with local flaps from scrotum or abdominal wall. Urethritis occurred in 2 patients 6 to 9 months after the transplantation of hinge-like flaps from scrotum, and they were cured by appropriate drugs. Functions of urination and erection of penis were recovered in these 4 patients. All flaps survived in the 5 patients repaired with hinge-like flaps from abdominal wall or prelaminated flaps from forearm. The wounds in 2 patients healed; wound dehiscence occurred in the other 3 patients in different degrees, and they healed after suturing for 2 or 3 times. The function of erection of penis recovered in these 5 patients, but with discontinuity of urinary stream during urination. Among them, 3 married patients enjoyed satisfactory sexual life. All free forearm flaps survived and the wounds healed well in 4 patients. Urinary fistula occurred in 1 patient, and it was repaired by a secondary operation. These 4 patients experienced normal urination function, but only 2 patients in whom corpus spongiosum partially remained retained the function of erection of penis to certain degree. All these 4 patients could not perform normal sexual intercourse. All patients were followed up for 6 to 13 months after surgery. Under ordinary state, the length of penis was 5.9-9.3 cm, and the circumference of penis was 8.4-10.0 cm. Wound scar was not obvious in all cases. Nine patients reported a restricted erection.

CONCLUSIONSPenile defect caused by devastating electrical burn should be repaired with a suitable flap after necrotic tissues are removed with dressing change. To repair affected penis with necrosis of a small part of cavernous body and/or corpus spongiosum, or combined with urethra defects, local flaps from scrotum or abdominal wall or hinge-like flap from scrotum should be employed. To repair those with necrosis of a large part or the whole of corpus spongiosum combined with urethra defects, hinge-like skin flaps from abdominal wall or prelaminated flaps from forearm should be employed. In patients with necrosis of a large part of cavernous body and corpus spongiosum combined with urethra defect, or total loss of penis, free forearm flaps should be employed to reconstruct penis.
