Objective To investigate the reconstructive method with better sensory and erectile function for partial penile defect. Methods The procedure was as follows: dissecting the suspensory ligaments and separating part of crus,the local fat flap was transferred to fill the front space of symphysis ossium pubica.Various pedicle skin flaps were designed as covering materials.Penis residual stump was advanced to anterior portion of the newly reconstructed penile body as “glans”.The post-operative follow-up included taking full layer skin of penis from the patients to observe neurofibril regeneration by light microscope, electron microscope and scanning electron microscope;determining sensation recovery by physical examination;and checking erectile function with NEVA system. Results 42 patients underwent the above mentioned procedures.In these cases,the length of the penis varied from 0.5～4.0 cm in flaccid,1.5～5.0 cm in erect state before operation to 5.0～8.0 cm in flaccid,7.0～12.5 cm in erect state after operation.28 patients were followed up for more than 1 year.Of them 23 men got married with acceptable sexual activity;in them 18 had their children.The microscopic examination showed that the tenuous wavy peripheral nerves were well differentiated and no denaturation and necrosis were observed in the dermis,near subcutaneous adipose and around eccrine glands.The positive granules could be seen in the cytoplasm of regenerative neurofibrils by immunohistochemistry technique.The regenerative neurofibrils and related tissues could be seen under scanning and transmission electron microscope.The penis presented normal pain,touch feeling and 2-point identification ability in more than 12 months after surgery.Over 12 months after surgery,the patient had gained 4～9 events during 8～12 hours of sleep, and the durations were 4 to 37 min;the volume changes were from 114% to 505% over baseline. Conclusions With this method,the reconstructed penis tends to have better appearance and functions.For penile partial defect it is superior to the conventional operation.

Objective: To observe the clinical efficacy of tuina at head and abdomen for headache due to phlegm turbidity. Methods:A total of 56 patients with headache due to phlegm turbidity were randomized into a tuina group and a Chinese medicine group by the random number table, with 28 cases in each group. The tuina group was treated mainly with tuina at the head and abdomen, while the Chinese medicine group was treated with oral administration of Ban Xia Bai Zhu Tian Ma Tang(Pinellia, Atractylodes Macrocephala and GastrodiaDecoction). The course of treatment was 30 d. The scores of headache index, traditional Chinese medicine syndrome scale, and the therapeutic efficacy were observed. Results:There were 2 dropouts in each group during treatment. The total effective rate was 92.3％ in the tuina group, significantly higher than 76.9％ in the Chinese medicine group (P<0.05). The scores of headache index and traditional Chinese medicine syndrome scale in both groups decreased after treatment (bothP<0.05), and scores in the tuina group were lower than those in the Chinese medicine group (bothP<0.05). Conclusion:Tuina mainly at head and abdomen is effective in treating headache due to phlegm turbidity, and has a better effect than Ban Xia Bai Zhu Tian Ma Tang (Pinellia, Atractylodes Macrocephala and GastrodiaDecoction).

OBJECTIVETo study the effect of Wenhua Juanbi Recipe (WJR) on proliferation and apoptosis of synoviocytes in rats with collagen-inducing arthritis (CIA).

METHODSA CIA model was induced by intradermal injection of bovine collagen type II emulsion at the base of rat tails. Thirty modeled healthy Wistar rats were randomly assigned to one of three groups (10 per group): the model group, the methotrexate (MTX)-treated group (0.78 mg/kg) and the WJR-treated group (22.9 g/kg). A group of 10 healthy rats was used as normal control. Treatments or normal saline for the control group were administered by oral gavage once daily. Rats were sacrificed after 30-day treatment and subjected to the following examinations: arthritis index (AI) was estimated, inflammatory cell infiltration and proliferation in synovial membrane were evaluated by microscopy, the synoviocyte apoptosis was determined by TUNEL assay, and the cell apoptosis index was calculated.

RESULTSAI was lowered significantly in the WJR group compared to the model group (P<0.01). The pathological findings observed in the model group were reversed in the WJR group, including increase in inflammatory cell infiltration and synoviocyte proliferation in synovial membrane and reduction in cell apoptosis index (all P<0.01).

CONCLUSIONSSynoviocyte proliferation and apoptosis reduction were present in CIA rats. WJR was effective in treating the rat model of CIA. The therapeutic effect might be exerted through inducing apoptosis and suppressing proliferation of synoviocytes.

AIMTo observe the expression of estrogen receptors alpha and beta in human tongue squamous cancer line Tca8113 cell, and to study the influence of beta-estradiol (beta-E2) on the proliferation and cell cycle of cultured Tca8113 cell.

METHODSImmunocytochemistry and RT-PCR methods were used to observe the expression of estrogen receptors (ER) in human tongue squamous carcinoma line Tca8113 cell. 3H-TdR incorporation and cell cycle analysis were used to examine the change of proliferation and DNA synthesis of Tca8113 cell.

RESULTSER-alpha and ER-beta mRNA were expressed in human tongue squamous cancer cell, and the expression of ER-beta was weaker than that of ER-alpha. beta-Estradiol at 10(-8) mol/L - 10(-6) mol/L could increase the proliferation of human tongue squamous carcinoma cell in a dose dependent manner (P < 0.01). beta-E2 (10(-6) mol/L) could increase the proportion of cells in S phase and G2 phase from 23.5% up to 37.7%. The effect of estradiol on the proliferation of cultured human tongue squamous cancer line Tca8113 cell could be inhibited by Tamoxifen.

CONCLUSIONThere are ER-alpha and ER-beta expression in human tongue squamous cancer line Tca8113 cell, and beta-estradiol promotes the proliferation and cell cycle of cultured human Tca8113 cell.

Atrial fibrillation (AF) is one of the most serious arrhythmias with high morbidity and mortality in clinic,which usually results in stroke,heart failure and peripheral vascular embolization,etc.Its prevalence is set to increase with widespread population ageing,causing enormous economic and social burden.Currently,medication is the common treatment method for atrial fibrillation.However,there is inefficient with a risk of arrhythmia.In recent years,noncoding ribonucleic acids (RNAs) play an important role in ontogenesis and the development of many diseases.More and more studies show that noncoding RNAs are closely related to the occurrence and maintenance of atrial fibrillation.Investigating the molecular mechanisms and interactive networks of noncoding RNAs have important significance on providing early prediction of AF susceptibility,evaluating the prognosis of patients and finding new therapeutic targets.The purpose of this report is to systematically review the molecular mechanisms of noncoding RNAs in the development and maintenance of AF.

Objective To investigate the combined effect of rosuvastatin (RSV) and ischemic postconditioning (PC) on myocardial ischemia-reperfusion (I/R) injury in a type 2 diabetic rat model. Methods Type 2 diabetic ( induced by streptozotocin plus nicotinamide) rats, undergoing 30 min ischemia and 120 min reperfusion, were divided into six groups (n = 10 each): Sham, I/R without other interventions, RSV before reperfusion, PC with 3 cycles of 10 s reperfusion and 10 s ischemia, RSV + PC and RSV + PC + PI3-K inhibitor LY294002. Myocardial infarct size (IS), ultrastructural change and myocardial expression of phosphorylated eNOS/total eNOS were determined. Results IS and ultrastructural damages were all significantly reduced and myocardial eNOS phosphorylation was significantly increased in RSV and PC groups compared with the L/R group (all P < 0. 05 ) these benefical effects were further enhanced by RSV + PC ( all P < 0. 05 vs. RSV and PC, respectively). The beneficial effects were significantly attenuated by PI3K inhibitor LY294002. Conclusions The results indicate that RSV + PC could alleviate myocardial ischemia-reperfusion injury in this type 2 diabetic model by activating PI3K/AKT/eNOS signaling pathway.

OBJECTIVETo investigate the anatomy of penis and its adjacent organ for phalloplasty.

METHODSAnatomic dissection of penis and perineum was performed on 30 adult male cadavers (60 sides). Observation and measurement were focused on the penile length of different parts, the morphological relationship of infundibular ligament and suspensory ligament with penile radix, and the feature of crus penis with relation to the deep penile artery.

RESULTSThe average length of the penile shaft was 8.13 cm, the penile radix was 7.67 cm and the crus penis was 5.96 - 5.98 cm. The deep penile artery penetrated into the crus penis at its middle 1/3. The infundibular ligament attached to superficial fascia of the penis and extended downward to the scrotal septum to constitute the suspensory structure for both of them. The suspensory ligament attached to the dorsal deep fascia of the penis. Becoming thicker, the rear part of the suspensory ligament connected firmly to the pubic arcuate ligament to constitute a part of suspensory mechanism for the urethra. There was a part of cavernous body, which was free from either ligament or bony attachment, between the penile radix and the crus penis, where the dorsal artery and nerve of penis turned around from the ventral to the dorsal aspect of the penis and the penile dorsal vain penetrated the urogenital septum, draining into intrapelvic venous plexus.

CONCLUSIONSThe divisional measurement of the penis length, the recognition of the suspensory ligaments and the anatomic feature of the crus penis with relation to the deep penile artery are all of significant importance to improve the operation of phalloplasty.

BACKGROUND: Although Becker's nevus (BN) is a relatively common disease, the systematic studies of clinicopathological and immunohistochemical results are poorly reported. OBJECTIVE: To investigate the clinicopathological features and immunohistochemical alterations of keratinocyte proliferation, melanocyte density, smooth muscle hyperplasia and nerve fiber distribution in BN. METHODS: Clinical and pathological data were collected in 60 newly-diagnosed BN cases. Immunohistochemical stain of Ki-67, Melan-A, keratin 15, smooth muscle actin and protein gene product 9.5 was performed in 21 cases. RESULTS: The median diagnostic and onset age was 17 and 12 years, respectively. Skin lesions usually appeared on the upper trunk and upper limbs. The pathological features included the rete ridge elongation and fusion and basal hyperpigmentation. Epidermal Ki-67, Melan-A and keratin 15 expression and dermal nerve fiber length were significantly higher in lesional and perilesional skin than in normal skin (p<0.05~0.01), while smooth muscle actin expression was upregulated only in skin lesion (p<0.05). CONCLUSION: Although the clinical diagnosis of BN is often straightforward, histopathology is helpful to differentiate from other pigmentary disorders. The hyperproliferation of keratinocytes, melanocytes, arrector pili muscle and dermal nerve fibers could be involved in the pathogenesis of BN.
