OBJECTIVETo investigate the mothod and therapeutic efficacy of total hip anthroplasties (THA) for osteoarthritis secondary to Crowe type IV developmental dysplasia of hip in adults.

METHODSFrom May 2006 to December 2013, THA was performed on 15 adult patients (17 hips) with Growe type IV acetabular dysplasia, including 13 females and 2 males, with a mean age of 30.9 years old (22 to 58 years old) and an average preoperative Harris score of (34.0 ± 6.5) points. Traction of the affected limb was not performed before surgery. After extensive release and lengthening of soft tissues, sub-trochanteric osteotomy of the femur was performed, hip joint center was rebuilt and the abduction function was restored.

RESULTSThe patients were followed up with a mean period of 33 months (ranged from 6 months to 5 years). The postoperative Harris score was 85.0 ± 7.3,higher than the preoperative score. The extended length of limb ranged from 1.6 to 5.4 cm, with a mean of (3.42 ± 0.65) cm. The shortening and malformation of the affected limb were corrected in the most patients,with the difference in length of the two legs less than 1.5 cm. After surgery, 1 patient experienced partial sciatic nerve injury, which was largely recovered after 3 months of conservative treatment. One patient experienced complete sciatic nerve injury, which was partially recovered after 6 months of conservative treatment; a foot-drop varus deformity was formed in the distal end of the affected limb, which was improved after tendon transposition and transplantation. Joint pain was relieved, and the joint function was restored significantly. Over the follow-up period, no severe complications such as dislocation, infection, prosthesis loosening, or subsiding occurred.

CONCLUSIONSatisfactory efficacy can be achieved for adult Growe type IV acetabular dysplasia associated with osteoarthritis by THA, with proper soft tissue release and lengthening, sub-trochanteric osteotomy of femur, joint functional restoration, appropriate choice of prosthesis, and careful protection of nerves and vessels.

The IL-8 and MMP-7 genes participate in the carcinogenesis of many malignancies, but the role of both genes in cervical cancer is not fully elucidated. The aim of this study was to determine the frequency of IL-8 and MMP-7 gene mutations and to assess their effects on the risk of early stage cervical cancer and lymph node metastasis. The clinical stage and histological grade of cervical cancer were also studied. The peripheral blood from the patients with early stage cervical cancers and normal controls was collected and the DNA was extracted. The incidence of IL-8 and MMP-7 gene mutations was assessed by using tetra-primer amplification refractory mutation system polymerase chain reaction (ARMS PCR) and restriction fragment length polymorphism (RFLP). The data were statistically analyzed by x2 test. The results showed that: (1) The genotype frequency of IL-8 -251AT and TT was significantly higher in the cervical cancer group than in the normal control group (OR=2.290 and 2.619 respectively, P=0.001), and it was also higher in the lymphatic metastasis group than that without metastasis (OR=2.917, P=0.035); (2) The frequency of MMP-7 -181G/G genotype was significantly higher in the cervical cancer group and in the lymphatic metastasis group (P<0.05); (3) The incidence of IL-8 mutation was two times higher in IIa cervical cancer group than in Ib1 and Ib2 cervical cancer group (P=0.006). For the MMP-7 gene, there was statistically significant difference in the incidence of mutation between the Ib1, Ib2 and the IIa (P=0.000); (4) Different histological types and different grades of cervical cancer had different incidence of mutations, statistically. It was suggested that there was significant difference in the genotype of IL-8 -251TT and MMP-7 -181GG polymorphism between the cervical cancer group and the lymph node metastasis group. Moreover, individuals with IL-8 T allele or MMP-7 G allele carriers were at significantly higher risk of cervical cancer, particularly the early (IIa) and medium, poorly differentiated cervical cancer (G2+G3).

OBJECTIVETo identify the causes of respiratory complications following liver transplantation (LT) and to discuss the management of these complications.

METHODSOne hundred and twenty four cases with pulmonary complications in the first two weeks after LT were identified among 163 patients admitted to the First Affiliated Hospital, College of Medicine, Zhejiang University from February, 1999 to March, 2003.

RESULTSThe incidence rate of complications was 76%(124/163) with the total cure rate of 92%(114/124). The cure rates of the various complications were as follows: pleural effusion 100%(113/113), pneumonia 92%(76/83), respiratory insufficiency 91%(59/65), pulmonary hypertension 98%(101/103), pulmonary edema 98(58/59), atelectasis 100%(4/4) and pneumothorax 100%(2/2).

CONCLUSIONTo drainage the pleural effusion with an unicameral venous catheter is safety and effective. To cure or prevent pneumonia and atelectasis, aseptic manipulating, aspiration of sputum and keeping respiratory channel open were the key measurements of treatment. Restrictive ventilatory functional disturbance (RVFD) and dysfunction of ventilation are two major types of respiratory insufficiency in early stage of post-transplantation. The causes of pulmonary hypertension and edema are associated with pulmonary angiotasis and blood flow volume, and the vasodilator and diuretic often introduced in the therapy.

OBJECTIVETo investigate the effect of Compound Qingqin Liquid (CQL) on the expression level of angiotensin II (Ang II) and COX-2 mRNA transcription and protein expression in the renal tissue of rats with uric acid nephropathy.

METHODSSD rats were randomly divided into the blank control group, the model group, the positive drug group, the high, moderate, and low dose CQL group according to number randomization principle. The model was established by gastrogavage of adenine, accompanied with yeast feeding. Distilled water was given by gastrogavage to rats in the blank control group and the model group. Allopurinol at the daily dose of 9.33 mg/kg was given by gastrogavage to rats of the positive control group. CQL at the daily dose of 3.77 g/kg, 1.89 g/kg, and 0.09 g/kg was respectively given by gastrogavage to rats in the high, moderate, and low dose CQL groups. All treatment lasted for 6 weeks. Rats were randomly divided at week 4 (3 in the blank control group, and 6 in the rest groups), and the rest rats were killed at week 6. The renal tissue was extracted. The expression level of Ang II and COX-2 mRNA transcription were detected by RT-PCR. The expression level of Ang II was detected by ELISA. The expression level of COX-2 protein was detected by Western blot and immunohistochemical assay.

RESULTSCompared with the blank control group, except the mRNA expression of Ang II at week 4, the mRNA and protein expression of Ang II and COX-2 obviously increased at week 4 and 6 in the model group (P < 0.01, P < 0.05). The COX-2 protein expression at week 4 was obviously lower in the high and moderate dose CQL groups than in the model group and the low dose CQL group (P < 0.05); the average integral of optical density value was obviously lower in the positive control group than in the model group. Except the mRNA expression of Ang II in the high dose CQL group at week 6, the mRNA and protein expression of Ang II obviously decreased in the positive control group and each dose CQL group (P < 0.01, P < 0.05). Of them, the effects were better in the high and moderate dose CQL groups than in the positive control group and the low dose CQL group (P < 0.05, P < 0.01). Besides, the mRNA expression of COX-2, the average integral of optical density value were obviously lower in the positive control group and each dose CQL group than in the model group (P < 0.05). The protein expression of COX-2 was obviously lower in the high and moderate dose CQL groups than in the model group (P < 0.05). Of them, the mRNA expression of COX-2 was better in the moderate dose CQL group than in the positive control group (P < 0.05); the protein expression of COX-2 was better in the high dose CQL group than in the low dose CQL group (P < 0.05).

CONCLUSIONCQL was capable of lowering the expression level of Ang II, COX-2 mRNA transcription and protein expression, thus suppressing the inflammatory pathological injury of the renal tissue.

OBJECTIVETo identify the electrophysiological properties of long-QT syndrome (LQTS) associated missense mutations in the outer mouth of the HERG potassium channel in vitro.

METHODSMutations V630A and N633S were constructed by Megaprimer PCR method and cRNA were produced by T7 RNA polymerase. The electrophysiological properties of the mutation were investigated in the Xenopus oocyte heterologous expression system.

RESULTSCoexpression of mutant and wild-type HERG subunits caused a dominant-negative effect, and the currents were significantly decreased. Compared with wild-type HERG channels, V630A and N633S mutations were related to decreased time constants for inactivation for V630A/WT and N633S/WT at all potentials, reduced slope conductance and the voltage dependence of steady-state inactivation was shifted to negative potentials for V630A/WT and N633S/WT.

CONCLUSIONPresent study shows that LQTS associated missense mutations located in the outer mouth of HERG cause a dominant-negative effect and alterations in steady-state voltage dependence of channel gating of heteromultimeric channels suggesting a reduction in expressional current might be one of the pathophysiologic mechanisms of LQTS.

Objective: This study aimed to determine the effect of radiotherapy (RT) on the risk of herpes zoster (HZ) in patients with gynecological cancers via a nationwide population-based study. Methods: Based on patient data obtained from the National Health Insurance Research Database, 1928 gynecological cancer patients were identified with 1:1 matching for RT and non-RT cohorts by age, index date, and cancer type. Another cohort consisting of 964 noncancer individuals matched was used as normal control. The incidence of HZ was compared between cancer patients with and without RT. Age, comorbidities, cancer-related surgery and chemotherapy (CT), and cancer type were adjusted as confounders. Results: The risk of HZ in cancer patients was higher than that of non-cancer individuals (14.23 versus 8.34 per 1,000 person-years [PY], the adjusted hazard ratio [aHR]=1.38, p=0.044). In the cancer population, the incidence of HZ for the RT and non-RT cohorts was 20.55 versus 10.23 per 1,000 PY, respectively (aHR=1.68, p=0.009). Age >50 years was an independent factor for developing HZ. The 5-year actuarial incidence for patients receiving neither RT nor CT, RT alone, CT alone, and combined modalities was 5.4%, 6.9%, 3.7%, and 9.9%, respectively (p<0.001). In the RT cohort, the risk rose rapidly in the first year, becoming steady thereafter. Conclusion This population-based study showed that gynecological cancer patients receiving RT combined with CT had the highest cumulative risk of HZ. Health care professionals should be aware of the potential toxicities.

Objective To compare the effects of butorphanol and fentanyl for postoperative patient controlled intravenous analgesia (PCIA), and explore the different nursing measures. Methods 100 patients were randomly divided into two groups with 50 cases each:group A(butorphanol),and group B (fentanyl). The PCA model for both groups was set with background infusion 2 ml/h, bolus of 2 ml with lock time 15 min. The Blood Pressure(BP), heart rate(HR), analgesic score (VAS), sedation score, patient satisfaction, nausea, vomiting, respiratory, sleep quality, gastrointestinal peristalsis, urinary retention were observed at 4,12,24,36 hours after operation. Results Adequate analgesia and patient satisfaction were achieved in both groups. The sedation score was higher in group A than group B(P>0.05). There were higher incidence of nausea, vomiting among B group. Conclusions With close clinical observation and reasonable nuring care, butorphanol and fentanyl could both provide satisfactory analgesia and sedation effects. However, the sedation score was higher in butorphanol and nurses should pay attention to patients' sleep quality. There were higher incidence of nausea, vomiting among patients with fentanyl, so nurses should pay attention to prevent patients from respiratory depression.
