Rectal cancer is a common malignancy in the alimentary tract with an increasing incidence, the current treatments of which include surgery, radiotherapy, chemotherapy, and integrated comprehensive options. Sexual dysfunction, especially erectile dysfunction (ED), is one of the commonest complications in men after rectal cancer treatment and is generally attributed to the damage to the pelvic autonomic nerves. However, recent studies show that ED after rectal cancer treatment is a complex pathophysiological process associated with neurogenic, vasculogenic, and psychological factors. This article reviews the pathogeneses of ED after rectal cancer treatment in order to provide some theoretical evidence for its prevention and treatment.

To synthesize salbutamol immunogen and develop an enzyme immunoassay (ELISA), a new salbutamol immunogen was synthesized using 4-aminobenzoic acid as a linker to connect hapten with carrier protein. An enzyme immunoassay based on the antibody prepared was developed and applied to detect salbutamol residue spiked in swine liver. An unusual coating antigen, clenbuterol-ovalbumin (OVA) conjugate instead of salbutamol-OVA conjugate, was used in the immunoassay and the results were discussed based on the structures of related compounds. The antibodies showed high sensitivity in the heterologous assay when using clenbuterol-OVA as a coating antigen, with an IC50 value of 8.97 ng mL(-1) toward salbutamol. The antibodies prepared showed high cross-reactivity with clenbuterol (107%) and were promising for the simultaneous determination of salbutamol and clenbuterol residues in food and food products. Recovery rates from the salbutamol-spiked swine liver samples were in the range of 70%-99%, while the intra-assay and inter-assay coefficients of variation were <13.3% and <14.3%, respectively. In summary, the antibodies of salbutamol have been successfully prepared. Sensitive and stable analysis for the detection of salbutamol residues in swine liver was obtained based on the competitive ELISA methods developed in this study.

Sildenafil increases the cyclic guanosine monophosphate (cGMP) by inhibition of a phosphodiesterase 5, thereby leading to an antinociceptive effect. The increased cGMP may exert the effect on an L-type calcium channel through the activation of protein kinase G (PKG). The purpose of this study was to examine the possible involvement of a PKG-L-type calcium channel on the effect of sildenafil at the spinal level. Catheters were inserted into the intrathecal space of male SD rats. Pain was induced by applying 50 microliter of a 5% formalin solution to the hindpaw. The sildenafil-induced effect was examined after an intrathecal pretreatment of a PKG inhibitor (KT 5823), or a L-type calcium channel activator (FPL 64176). Intrathecal sildenafil produced an antinociceptive effect during phase 1 (0~10 min interval) and phase 2 (10~60 min interval) in the formalin test. Intrathecal KT 5823 and FPL 64176 attenuated the antinociceptive effect of sildenafil during both phases. Sildenafil is effective against both acute pain and the facilitated pain state at the spinal level. In addition, the inhibition of an L-type calcium channel by activation of the PKG may contribute to the antinocieptive mechanism of sildenafil in the spinal cord.

OBJECTIVETo evaluate the efficacy of abdominal acupuncture for adhesion-stage shoulder periarthritis.

METHODSOne hundred and fifty-seven cases of shoulder periarthritis were randomly divided into an abdominal acupuncture group (79 cases) and a body acupuncture group (78 cases). The abdominal acupuncture was applied at Zhongwan (CV 12), Shangqu (KI 17) and Huaroumen (ST 24) in the abdominal acupuncture group while conventional acupuncture was applied at Jianyu (LI 15), Jianliao (TE 14) and Jianzhen (SI 9) in the body acupuncture group. The treatment was given three times a week for both groups and ten times made an observation course. Before and after treatment, visual analogue scale (VAS) was adopted for pain assessment and functional activity score (Mallet score) was used for shoulder joint function assessment for all the patients. Also the efficacy of both groups was compared.

RESULTSThe total effective rate in the abdominal acupuncture group was 92.4% (73/79), which was superior to 71.8% (56/78) in the body acupuncture group. The score of VAS after the treatment was 2.58 +/- 1.64 in the abdominal acupuncture group while 3.12 +/- 1.93 in the body acupuncture group, which had no statistical significance between each other (P > 0.05). The functional activity score after the treatment was 8.34 +/- 3.02 in the abdominal acupuncture group while 7.49 +/- 3.36 in the body acupuncture group, which had no statistical significance between each other (P > 0.05).

CONCLUSIONThe abdominal acupuncture is an ideal treatment for adhesion-stage shoulder periarthritis, which has better total efficacy than conventional acupuncture. It achieves the same effect in relieving pain and improving functional activity as conventional acupuncture, but also has an advantage at fast selection of acupoint and less discomfort of needling sensation.

OBJECTIVETo observe the efficacy of thread-moxa in Zhuang folk medicine (TM) combined with acupuncture and external application drugs for AIDS patients with herpes zoster (AHZ).

METHODSA randomized, controlled clinical trial was conducted in 60 patients with AHZ. They were randomly assigned to the treatment group (treated with TM combined with acupuncture and Jingwanhong Scald Ointment) and the control group (treated with Famciclovir Tablet, nimesulide dispersible tablet, vitamin B1, ribavirin ointment). The treatment course was 14 days for both groups.The clinical efficacy, significant efficiency visual analog scale score (VAS), sleep quality score (QS), the postherpetic neuralgia rate in 1 year after treatment were observed.

RESULTSThe markedly effective rate was significantly higher in the treatment group than in the control group (86.7% vs. 53.3%, P < 0.01). There was no statistical difference in the total effective rate between the two groups (96.7% vs. 80.0%, P > 0.05). The post-treatment VAS, QS, the time for pain disappearance, skin repair, crusting, and 1-year postherpetic neuralgia incidence rate were significantly lower in the treatment group than in the control group (P < 0. 05, P < 0.01).

CONCLUSIONSTM combined with acupuncture and Jingwanhong Scald Ointment was effective for treating AHZ patients. It relieved pain quickly, shortened their course of disease, and improved their quality of sleep.

AIM:To investigate the effect of histone deacetylase 1(HDAC1)silencing on apoptosis of squa-mous cell carcinoma of skin.METHODS:Skin squamous cell carcinoma A431 cells were transfected with HDAC1 small interfering RNA(HDAC1 siRNA)or small interfering RNA negative control(siRNA NC).The expression levels of HDAC1 in transfected cells were detected by RT-PCR and Western blot.The cell viability was measured by MTT assay, and the apoptosis was analyzed by flow cytometry.The protein levels of STAT3,p-STAT3 and cleaved caspase-3 were de-termined by Western blot.The inhibitor of STAT3 signaling pathway was used to treat the A 431 cells transfected with HDAC1 siRNA.The cell viability was detected by MTT assay,the apoptosis was analyzed by flow cytometry,and the pro-tein levels of STAT3,p-STAT3 and cleaved caspase-3 were determined by Western blot.RESULTS: HDAC1 siRNA in-hibited the expression of HDAC1 at mRNA and protein levels in the A431 cells.After interfering with the expression of HDAC1,the cell viability and the protein level of p-STAT3 in the cells decreased,while the apoptotic rate and the protein level of cleaved caspase-3 in the cells were increased.After treatment with the inhibitor of STAT3 pathway,the viability of A431 cells transfected with siRNA and the protein level of p-STAT3 decreased,while the apoptotic rate and the protein le-vel of cleaved caspase-3 in the cells were increased.CONCLUSION: Interference with HDAC1 expression may regulate the STAT3 signaling pathway to inhibit the viability of skin squamous cell carcinoma cells,thus promoting the apoptosis of squamous cell carcinoma of skin.

Objective To evaluate the diagnosis and treatment of 37 cases of popliteal vascular entrapment syndrome (PVES).Methods The clinical data of 37 PVESA cases (44 limbs) from July 2004 to July 2016 was retrospectively analyzed.There were 28 men and 9 women,age ranging from 7 to 74 years.They all underwent B-us,CTA,MRA or DSA examination before the operation.Surgical procedures performed on 38 limbs included musculo-tendinous division,popliteal-popliteal interposition,femoralpopliteal bypass.Result One patient died of PE one day after operation.The ankle brachial index (ABI)increased from 0.54 ±0.31 to 0.87 ±0.23 after operation (P ＜0.01).30 cases were followed-up with a mean followup time of 43.8 months and intermittent claudication were relieved in all cases.Conclusions PVES is an extremely important cause of non-arteriosclerotic lower extremity arterial chronic ischemia which need early,active and appropriate surgical intervention.

Objective To study the genetic variations between measles vaccinc strain S191 and strains that circulated in Zhejiang province causing the epidemics during 1999 to 20 1 1.Methods Complete sequence of the nine Zhejiang measles strains were amplified by RT-PCR assay.Products were sequenced and the obtained sequences were aligned and analyzed with vaccine strains S191 and the major epidemic strains isolated in foreign countries.Results The homology of amino acid among the nine Zhcjiang strains were 98.77％-99.89％.The strains were not affected by positive selection and the variations on each gene were still in random drift.Compared to vaccine strain S191,there were 135 to 159 amino acid changes in Zhejiang measles virus,in which 113 points were common variable positions,resulting in mutations on five glycosylation sites.At the nucleotide level,the biggest differences between the Zhejiang strains and the vaccine strain S191 were found on N gcne,with the average divergent ratio as 5.5％,while the biggest one was P protein,in the amino acid level,with the average mutation rate as 7.7％.In addition,with the complete genome sequences,the genetic distance between Zhcjiang epidemic strains and vaccine strains was greater than the distances between epidenic strains of genotype D4,B3 and vaccine strains (t=-9.76,P＜0.05；t=-12.39,P＜0.05).Conclusion There were significant differcnccs found in the each of the genes between Zhejiang epidemic strains and the vaccine strain S191.The differences between the current vaccine strains and H genotypc epidemic strains were much larger than the differences between the vaccine and the forcign epidemic strains (genotype D4,B3).Therefore,wc should pay close attcntion to this trend,and to develop candidates for the dcvclopnent of vaccines,as early as possible.
