Objective To observe the short-term clinical efficacy of modified transanal Soave surgery on infants with hirschsprung′s disease (HD) in initial radial resection, and to analyze the influencing factors. Methods 132 HD infants were selected. After initial radial resection with modified transanal , Soave surgery was conducted under general or sacral anesthesia. Postoperative antibiotics were routinely given. Results 19-56 cm intestinal canal samples were excised, with average length of (35.07 ± 3.15) cm. The average surgical duration and intra-operative hemorrhagic volume were (120.48 ± 18.34) min and verage was (45.74 ± 8.14) mL. All infants′ gastrointestinal function was recovered in 24 h postoperatively. The total excellent and effective rate of anal function in 6 months was 90.90% postoperatively. Cox modal multivariate analysis suggested that anastomotic orifice stenosis and enteritis were the two factors that greatly influenced the excellent and effective rate of anal function 6 months after the surgery (P < 0.05). Conclusion The modified transanal Soave surgery has small trauma and low complication rate on HD infants in initial radial resection , and the postoperative enteritis and anastomotic orifice stenosis are independent influencing factors for the short-term efficacy.

OBJECTIVE: To strengthen the occupational protection of pharmacy intravenous admixture service (PIVAS) staff, and to ensure the safe and timely delivery of drugs. METHODS: The cytotoxic drug packing bag was made by oxford cloth, velvet cotton, pearl cotton, silica gel, activated carbon, rope, etc. Taking Paclitaxel liposomes for injection as an example, the application effect of packing bags was observed. A total of 156 medical orders of PIVAS formulated Paclitaxel liposomes for injection were selected and divided into test group and control group aoccording to random number table. The dispensing drugs were packed with cytotoxic drug packing bag in trial group, and packed with previous plastic packing bag in control group. The packing time of each drug, the delivery time, leaking and shattering, the breakage processing time and loss amount were compared between 2 groups. RESULTS: There was no statistical significance in the delivery time between 2 groups (P＞0. 05). The packing time of trial group was significantly longer than control group; there were 16 bottles of leaking in the control group, and 8 bottles of shattering; In trial group, 3 bottles were leaking but not spilled over (infiltrated in the silica gel layer), and there was no shattering bottle; the breakage processing time of trial group was significantly shorter than that of control group; the loss amount was significantly less than that of control group, with statistical significance (P＜0. 05). CONCLUSIONS: The cytotoxic drug packaging bag developed in this study can play a spill-proof, anti-seismic role, reduce the loss of valuable drugs, and also strengthen the occupational safety and health protection of medical staff.

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.

Objective To analyze the long-term follow-up result of mammaplasty by autologous granular adipose transplantation.Methods In combination with literature review,the late result was studied by means of a 18 years follow-up in a case of mammaplasty with autologous granular adipose transplantation.Results In this case,2 cm thickness of adipose tissue was formed in submammary space,it lacked lobule structure,adipose cells appearred in different size in some region,and nerve fiber was not observed.Under the same observing condition,capillary quantity in this adipose tissue was more than that in normal subcutanous fat,and the difference was significant (P ＜0.05).Conclusions If appropriate operation is carried out,the autologous granular adipose transplantation would be a safe and effective mammaplasty.The tranplanted fat might form new adipose tissue,which could survive for a long time.

OBJECTIVETo study the severe acute respiratory syndrome (SARS)-associated coronavirus genotype and its characteristics.

METHODSA SARS-associated coronavirus isolate named ZJ01 was obtained from throat swab samples taken from a patient in Hangzhou, Zhejing province. The complete genome sequence of ZJ01 consisted of 29,715 bp (GenBank accession: AY297028, version: gi: 30910859). Seventeen SARS-associated coronavirus genome sequences in GenBank were compared to analyze the common sequence variations and the probability of co-occurrence of multiple polymorphisms or mutations. Phylogenetic analysis of those sequences was done.

RESULTSBy bioinformatics processing and analysis, the 5 loci nucleotides at ZJ01 genome were found being T, T, G, T and T, respectively. Compared with other SARS-associated coronavirus genomes in the GenBank database, an A/G mutation was detected besides the other 4 mutation loci (C:G:C:C/T:T:T:T) involved in this genetic signature. Therefore a new definition was put forward according to the 5 mutation loci. SARS-associated coronavirus strains would be grouped into two genotypes (C:G:A:C:C/T:T:G:T:T), and abbreviated as SARS coronavirus C genotype and T genotype. On the basis of this new definition, the ZJ01 isolate belongs to SARS-associated coronavirus T genotype, first discovered and reported in mainland China. Phylogenetic analysis of the spike protein gene fragments of these SARS-associated coronavirus strains showed that the GZ01 isolate was phylogenetically distinct from other isolates, and compared with groups F1 and F2 of the T genotype, the isolates of BJ01 and CUHK-W1 were more closely related to the GZ01 isolate. It was interesting to find that two (A/G and C/T) of the five mutation loci occurred in the spike protein gene, which caused changes of Asp to Gly and Thr to Ile in the protein, respectively.

CONCLUSIONAttention should be paid to whether these genotype and mutation patterns are related to the virus's biological activities,epidemic characteristics and host clinical symptoms.

OBJECTIVE: To investigate the correlation between the stenosis degree of superior mesenteric artery (SMA) and each artery within the scope of aorto-iliac artery in patients with lower extremity atherosclerotic occlusive disease (LEAOD). METHODS: Images of 70 patients who had undergone the aorta-iliac-femoral arteries CT angiography (CTA) examination and had a definite diagnosis of LEAOD due to intermittent claudication or resting pain admitted to Tianjin Hospital from January to December in 2017 were enrolled. The arteries in the aorta as well as iliac were surface-reconstructed, which were analyzed by advanced vascular analysis (AVA) combined with the original images, including SMA trunk, abdominal aorta (AA), left and right common iliac artery (LCIA, RCIA), left and right internal iliac artery (LIIA, RIIA), left and right external iliac artery (LEIA, REIA). The normal reference plane and the maximal stenosis plane were selected, and the stenosis rate of each artery in the reconstruction range was automatically calculated with software. The patient's imaging data were divided into groups with two methods: (1) according to the degree of SMA stenosis, the patients were divided into group I (stenosis degree ≤70%) and group II (stenosis degree > 70%); (2) LEAOD patients with different gender were respectively divided into three groups: middle-aged group (45-59 years old), pre-elderly group (60-74 years old) and elderly group (75-89 years old). The comparison between the stenosis degree of SMA and each artery within the scope of aorto-iliac artery was analyzed with Pearson simple correlation analysis. RESULTS: The incidence of SMA stenosis in all LEAOD patients was 100%. Correlation analysis showed that there was no correlation between the stenosis degree of SMA and AA, LCIA, RCIA, LIIA, RIIA, LEIA, or REIA in group I (n = 64) and group II (n = 6), respectively (r value was -0.021, 0.023, 0.023, -0.137, 0.182, -0.113, 0.141, respectively, in group I, and it was 0.020, -0.560, 0.010, 0.306, -0.204, -0.381, 0.393, respectively, in group II, all P > 0.05). In 52 male patients, there was no correlation between the stenosis degree of SMA and AA, LCIA, RCIA, LIIA, RIIA, LEIA, or REIA in middle-aged group (n = 16), pre-elderly group (n = 27) and elderly group (n = 9), respectively (r value was -0.032, 0.024, 0.324, 0.146, 0.312, 0.008, 0.344, respectively, in middle-aged group, it was -0.108, -0.116, -0.040, -0.249, -0.082, -0.052, 0.096, respectively, in pre-elderly group, and it was 0.182, 0.311, 0.400, 0.360, 0.688, 0.498, 0.406, respectively, in elderly group, all P > 0.05). In 18 female patients, there was also no correlation between the stenosis degree of SMA and above each artery within the scope of aorto-iliac artery in pre-elderly group (n = 11) and elderly group (n = 6), respectively (the r value was -0.170, 0.040, -0.019, 0.152, 0.508, 0.042, 0.456, respectively, in pre-elderly group, and it was -0.660, 0.008, -0.055, -0.056, -0.213, 0.344, 0.011, respectively, in elderly group, all P > 0.05). The correlation in middle-aged group was not analyzed because there was only 1 patient. CONCLUSIONS Although the atherosclerotic changes in LEAOD patients can affect SMA and aorto-iliac artery at the same time, there was no correlation between the stenosis degree of SMA and each artery within the scope of aorto-iliac artery which may due to the differences in the histological structure and hemodynamics among different arteries. SMA atherosclerotic stenosis and occlusion is a relatively independent disease process for LEAOD.

ObjectiveTo retrospectively analyze the clinical efficacy of Xibining Ⅱ prescription in the treatment of knee osteoarthritis with cold-dampness blockage syndrome by oral medication and to explore the influencing factors of endpoint events. MethodA real-world retrospective cohort design was adopted， and medical records of knee osteoarthritis patients with cold-dampness blockage syndrome treated with oral medication from the orthopedics outpatient department of Jiangsu Province Hospital of Chinese Medicine were collected. All patients received conventional Western medicine treatment and were divided into non-exposure group （573 cases） and exposure group （427 cases） according to whether or not they received treatment with Xibining Ⅱ prescription. Descriptive analysis of the baseline data of the 1 000 screened cases was performed using IBM SPSS 27.0. According to the baseline data， 334 pairs were matched using the propensity score matching method， resulting in a total of 668 cases in both groups. The changes in visual analogous scale （VAS）， Western Ontario and McMaster Universities Osteoarthritis Index （WOMAC） total score， Japanese Knee Osteoarthritis Measure （JKOM） score， and traditional Chinese medicine （TCM） syndrome score before treatment and at 2， 6， 12 weeks after treatment， as well as the incidence of adverse reactions， were compared between the two groups. A multivariate logistic regression analysis was conducted to analyze the influencing factors of endpoint events， with clinical cure judged based on the improvement rate of WOMAC total score before and after treatment. ResultAfter 12 weeks of treatment， compared to the results before treatment， the VAS， WOMAC total score， JKOM score， and TCM syndrome score of patients in both groups significantly decreased （P<0.01）. Compared to the non-exposure group， the exposure group showed a more significant reduction in VAS， WOMAC total score， JKOM score， and TCM syndrome score （P<0.01）. After 12 weeks of treatment， the clinical cure rate and significant efficiency were higher in the exposure group than in the non-exposure group （P<0.05）. Compared to the results before treatment within each group， VAS， WOMAC pain， stiffness， function scores， JKOM score， and TCM syndrome score significantly decreased at 2， 6， 12 weeks after treatment in both groups （P<0.01）. Compared to the non-exposure group at the same time points， the exposure group showed a reduction in VAS at 2， 12 weeks， WOMAC pain at 6， 12 weeks， and function scores at 12 weeks （P<0.05， P<0.01）. The JKOM score decreased at 6， 12 weeks， and the TCM syndrome score significantly decreased at 2， 6， 12 weeks in the exposure group （P<0.05， P<0.01）. Multivariate logistic regression analysis at 12 weeks showed that factors affecting clinical cure included the course of disease， history of alcohol consumption， hypertension， coronary heart disease， and the use of Xibining Ⅱ prescription （P<0.05， P<0.01）. Compared to the non-exposure group at the same time points， the incidence of epigastric discomfort in the exposure group was lower at 2， 12 weeks （P<0.01）， the incidence of diarrhea and vomiting was slightly higher than that in the non-exposure group， but the difference was not statistically significant. ConclusionThe clinical application of Xibining Ⅱ prescription combined with conventional Western medicine treatment in the treatment of knee osteoarthritis with cold-dampness blockage syndrome is more effective than conventional Western medicine treatment alone. It can significantly reduce VAS， WOMAC total score， JKOM score， and TCM syndrome score， with more pronounced long-term effects and a low incidence of adverse reactions.
